Referring to FIG. 6, the first state (601) may be a state in which the flexible circuit board (400) begins to be inserted into the connector (300). For example, the first state (601) may be a state in which the flexible circuit board (400) is inserted into the connector (300), and the plating layers (415, 475) of the flexible circuit board (400) and the first terminal (310) and the second terminal (320) are not in contact.

In the first state (601), the flexible circuit board (400) can be inserted into the connector (300) through the housing opening (333). In the first state (601), the flexible circuit board (400) can be inserted into the connector (300) without being caught by the catch (331) of the connector housing (330). For example, in the first state (601), the flexible circuit board (400) can be inserted into the connector (300) through the housing opening (333) with the ending portion (FP1, see FIG. 4) positioned in the positive Z-axis direction with respect to the catch (331).

Referring to FIG. 6, the second state (602) may be a state in which the flexible circuit board (400) moves between the first terminal (310) and the second terminal (320).

Referring to FIG. 6, the third state (603) may be a state in which the flexible circuit board (400) is fully inserted into the connector (300). For example, the third state (603) may be a state in which the flexible circuit board (400) is inserted into the connector (300) by a predetermined length and the flexible circuit board (400) is connected to the connector (300).

In the third state (603), the first plating layer (415) of the flexible circuit board (400) can be in at least partial contact with the first terminal (310) on the first side (400A).

In one embodiment, the first terminal (310) may include a first contact point (311). In the third state (603), the first terminal (310) may be in at least partial contact with the first plating layer (415) of the flexible circuit board (400) at the first contact point (311).

In one embodiment, the second terminal (320) may include a second contact point (321). In the third state (603), the second terminal (320) may be in at least partial contact with the second plating layer (475) of the flexible circuit board (400) at the second contact point (321).

Referring to FIG. 6, in the third state (603), a first pressure (F1) directed toward the flexible circuit board (400) at the first contact point (311) may be applied to the flexible circuit board (400). A second pressure (F2) directed toward the flexible circuit board (400) at the second contact point (321) may be applied to the flexible circuit board (400).

In one embodiment, the first pressure (F1) may be greater than the second pressure (F2). Since the first pressure (F1) is formed to be greater than the second pressure (F2), the flexible circuit board (400) may be subjected to a force in a direction toward the circuit board (500) (e.g., in the negative Z-axis direction). Since the first pressure (F1) is formed to be greater than the second pressure (F2), the flexible circuit board (400) may be prevented or reduced from being separated from the circuit board (500) in a state where the flexible circuit board (400) is connected to the connector (300).

In one embodiment, the first terminal (310) and the second terminal (320) may be electrically connected to the plating layer (415, 475) of the circuit board (500).

In one embodiment, the ending portion (FP1, see FIG. 5) of the flexible circuit board (400) can be inserted into the hollow portion (337) through the housing opening (333).

Referring to FIG. 7, when the ending portion (FP1, see FIG. 5) of the flexible circuit board (400) is connected to the connector (300), the first contact point (311) and the second contact point (321) can be set to contact the first surface (400A) and the second surface (400B) of the ending portion (FP1) of the flexible circuit board (400), respectively.

In one embodiment, the first plating layer (415) of the flexible circuit board (400) can be in at least partial contact with the first terminal (310) on the first side (400A). The second plating layer (475) of the flexible circuit board (400) can be in at least partial contact with the second terminal (320) on the second side (400B) opposite the first side (400A).

In one embodiment, the plating layer (415, 475) of the flexible circuit board (400) can be electrically connected to at least a portion of the first terminal (310) and the second terminal (320).

In one embodiment, the first terminal (310) may include a first contact point (311). The first terminal (310) may be in at least partial contact with a first plating layer (415) of a flexible circuit board (400) at the first contact point (311).

In one embodiment, the first terminal (310) may include a first bending region (313) that is convexly bent in a direction toward the flexible circuit board (400). Referring to FIG. 7, the first bending region (313) may be convexly bent in a first direction (e.g., in the negative Z-axis direction) and may include a first contact point (311).

In one embodiment, the first contact point (311) may be formed in the first bending region (313).

In one embodiment, the second terminal (320) may include a second contact point (321). The second terminal (320) may be in at least partial contact with the second plating layer (475) of the flexible circuit board (400) at the second contact point (321).

In one embodiment, the second terminal (320) may include a second bending region (323) that is convexly bent in a direction toward the flexible circuit board (400). For example, referring to FIG. 7, the second bending region (323) may be convexly bent in a second direction (e.g., the positive Z-axis direction) and include a second contact point (321).

In one embodiment, the second contact point (321) may be formed in the second bending region (323).

In one embodiment, the length of the first bending region (313) may mean the length by which the first bending region (313) extends in the Y-axis direction. The length of the first bending region (313) may be the first length (BL1).

In one embodiment, the length of the second bending region (323) may mean the length by which the second bending region (323) extends in the Y-axis direction. The length of the second bending region (323) may be the second length (BL2).

In one embodiment, the length of the first bending region (313) may be greater than the length of the second bending region (323). For example, the first length (BL1) may be greater than the second length (BL2).

In one embodiment, the first bending radius (BR1) of the first bending region (313) may mean the radius of curvature of the first bending region (313).

In one embodiment, the second bending radius (BR2) of the second bending region (323) may mean the radius of curvature of the second bending region (323).

In one embodiment, the first bending region (313) may have a greater degree of bending than the second bending region (323). For example, in one embodiment, the first bending radius (BR1) may be smaller than the second bending radius (BR2). Since the first bending radius (BR1) of the first bending region (313) is smaller than the second bending radius (BR2) of the second bending region (323), the degree of bending of the first bending region (313) may be greater than that of the second bending region (323).

In one embodiment, the first movable distance (L1) may be the distance from the portion (X1) where the first terminal (310) is fixed to the first contact point (311). The second movable distance (L2) may be the distance from the portion (X2) where the second terminal (320) is fixed to the second contact point (321).

In one embodiment, the first operating distance (L1) and the second operating distance (L2) may be formed differently. In one embodiment, the first operating distance (L1) and the second operating distance (L2) may be formed differently, so that the first pressure (F1) and the second pressure (F2) may be formed differently.

Although the first movable distance (L1) is illustrated as being longer than the second movable distance (L2) in FIG. 7, the relationship between the first movable distance (L1) and the second movable distance (L2) is not limited thereto, and the connector (300) according to one embodiment may be formed such that the first movable distance (L1) is shorter than or equal to the second movable distance (L2).

In one embodiment, the first terminal (310) may have a first thickness (t1). The second terminal (320) may have a second thickness (t2). In one embodiment, the thicknesses (t1, t2) of the terminals (310, 320) may be the lengths by which the terminals (310, 320) extend in the height direction (e.g., the Z-axis direction) of the connector (300).

In one embodiment, the first thickness (t1) may be formed differently from the second thickness (t2). For example, the first thickness (t1) may be thicker than the second thickness (t2).

In FIG. 7, the first thickness (t1) is illustrated as being thicker than the second thickness (t2), but the relationship between the first thickness (t1) and the second thickness (t2) is not limited thereto, and the connector (300) according to one embodiment may be formed such that the first thickness (t1) is thinner than or equal to the second thickness (t2).

Referring to FIG. 7, when a flexible circuit board (400) is connected to a connector (300), a first pressure (F1) and a second pressure (F2) can be applied to the flexible circuit board (400). The first pressure (F1) can be applied to the flexible circuit board (400) in a first direction (e.g., in the negative Z-axis direction) at a first contact point (311). The second pressure (F2) can be applied to the flexible circuit board (400) in a second direction (e.g., in the positive Z-axis direction) at a second contact point (321).

In one embodiment, the magnitudes of the first pressure (F1) and the second pressure (F2) may vary based on the thickness (t1, t2) of the terminal (310, 320), the deformation amount (D1, D2, see FIG. 10) of the terminal (310, 320), and/or the operating distance (L1, L2). For example, in one embodiment, the first pressure (F1) may be formed to be greater than the second pressure (F2) because the first thickness (t1) is thicker than the second thickness (t2). In one embodiment, the first deformation amount (D1, see FIG. 10) may be greater than the second deformation amount (D2, see FIG. 10), so the first pressure (F1) may be formed to be greater than the second pressure (F2).

In one embodiment, the first pressure (F1) may be greater than the second pressure (F2). For example, the first pressure (F1) may be approximately 18 gf, and the second pressure (F2) may be approximately 17 gf.

In one embodiment, since the first pressure (F1) is formed to be greater than the second pressure (F2), the flexible circuit board (400) can be forced in the negative Z-axis direction (e.g., toward the circuit board (500, see FIG. 6)). Since the first pressure (F1) is formed to be greater than the second pressure (F2), the flexible circuit board (400) can be prevented or reduced from being separated from the circuit board (500, see FIG. 6) when the flexible circuit board (400) is connected to the connector (300).

In one embodiment, the first contact point (311) and the second contact point (321) may be spaced apart in the width direction (e.g., Y-axis direction) of the connector (300). For example, the first contact point (311) and the second contact point may be arranged at a first separation distance (E) in the width direction (e.g., Y-axis direction) of the connector (300).

In one embodiment, the first contact point (311) may be located closer to the housing opening (333) of the connector housing (330) than the second contact point (321).

In one embodiment, the first contact point (311) and the second contact point are spaced apart from each other by a first separation distance (E) in the width direction (e.g., Y-axis direction) of the connector (300), and the first contact point (311) is located closer to the housing opening (333) than the second contact point (321), so that a rotational force (Q) formed by the first pressure (F1) of the first contact point (311) and the second pressure (F2) of the second contact point (321) can be transmitted to the flexible circuit board (400). The rotational force (Q) can prevent or reduce the flexible circuit board (400) from being separated from the circuit board (500).

Fig. 8 is a drawing showing a state in which a flexible circuit board (400) is connected to a connector (300) (e.g., state 603 of Fig. 6). Fig. 8 may be a drawing showing a cross-section of a connector (300) cut in a direction perpendicular to the height direction (e.g., Z-axis direction) of the connector (300) in a state in which a flexible circuit board (400) is connected to the connector (300).

Referring to FIG. 8, the flexible circuit board (400) may include an ending portion (FP1) and/or a flexible portion (FP2). In one embodiment, the ending portion (FP1) of the flexible circuit board (400) may be inserted into a connector (300).

Referring to FIG. 8, when the flexible circuit board (400) is connected to the connector (300), the protrusion (405) of the flexible circuit board (400) may overlap with the catch (331) of the connector housing (330). For example, the protrusion (405) of the flexible circuit board (400) and the catch (331) of the connector housing (330) may be positioned at substantially the same position based on the longitudinal direction (e.g., X-axis direction) of the connector (300).

Referring to FIG. 8, when a flexible circuit board (400) is connected to a connector (300), the flexible circuit board (400) can be positioned so that the contact surface (405A) of the protrusion (405) faces the catch (331) of the connector housing (330).

In one embodiment, when the flexible circuit board (400) is fastened to the connector (300), the engaging portion (331) of the connector housing (330) faces at least a portion of the flexible circuit board (400) and can prevent or reduce the flexible circuit board (400) from being detached from the connector (300).

FIG. 9a and FIG. 9b are drawings showing an operation of separating a connector (300) and a flexible circuit board (400) according to one embodiment of the present disclosure.

Fig. 9a is a diagram illustrating a first separation operation (700) according to one embodiment. Fig. 9b is a diagram illustrating a second separation operation (800) according to one embodiment.

In one embodiment, for example, the first separation operation (700) may be an operation to normally separate the flexible circuit board (400) from the connector (300). For example, the first separation operation (700) may be an operation to separate the flexible circuit board (400) without making contact with the engaging portion (331) of the connector (300).

In one embodiment, the first separation operation (700) may include a first operation (701) and/or a second operation (702).

In a first operation (701) according to one embodiment, a first separation force (B1) may be applied to a flexible circuit board (400). The flexible circuit board (400) may be moved away from the circuit board (500) by the first separation force (B1).

In one embodiment, the first operation (701) allows the flexible circuit board (400) to be moved such that the protrusion (405) does not come into contact with the catch (331).

In one embodiment, the flexible circuit board (400) is moved through the first operation (701) such that the flexible circuit board (400) does not overlap with the catch (331) of the connector housing (330).

In a second operation (702) according to one embodiment, a second separation force (B2) may be applied to the flexible circuit board (400). For example, the flexible circuit board (400) may be moved away from the connector (300) (e.g., in the negative Y direction) by the second separation force (B2).

In one embodiment, through the first operation (701), the flexible circuit board (400) is moved to a position where the protrusion (405) does not overlap with the catch (331) of the connector housing (330), so that when the flexible circuit board (400) is moved in the second operation (702), the flexible circuit board (400) may not come into contact with the catch (331) of the connector housing (330).

In one embodiment, the flexible circuit board (400) can be separated from the connector (300) through the first separation operation (700). In the first separation operation (700), the flexible circuit board (400) does not interfere with the engaging portion (331) of the connector (300), so that the separation of the flexible circuit board (400) and the connector (300) can be facilitated.

In one embodiment, the second separation operation (800) may be an operation forcibly separating the flexible circuit board (400) from the connector (300). For example, the second separation operation (800) may be an operation for separating the flexible circuit board (400) from the connector (300) while at least a portion of the flexible circuit board (400) (e.g., the protrusion (405)) is in contact with the engaging portion (331) of the connector (300).

In one embodiment, a third separation force (B3) may be applied to the flexible circuit board (400) in the second separation operation (800).

In one embodiment, the force applied in the first separation operation (700) may be smaller than the force applied in the second separation operation (800). For example, the first separation force (B1) applied in the first operation (701) of the first separation operation (700) may be approximately 8 N to 10 N. The third separation force (B3) applied in the second separation operation (800) may be approximately 13 N to 15 N.

Referring to FIG. 9b, at least a portion of the engaging portion (331) of the connector (300) may be formed in an asymmetrical shape. In one embodiment, the engaging portion (331) may include a first engaging surface (3311) facing the outside of the connector (300) and/or a second engaging surface (3312) facing the inside of the connector (300).

In one embodiment, the connector housing (330) may include a support surface (334) that contacts the circuit board (500).

Referring to FIG. 9B, the first engaging surface (3311) and the supporting surface (334) of the connector housing (330) may form a first angle (AG1). The second engaging surface (3312) and the supporting surface (334) of the connector housing (330) may form a second angle (AG2). The first angle (AG1) may be smaller than the second angle (AG2). In one embodiment, since the first angle (AG1) is formed smaller than the second angle (AG2), insertion of the flexible circuit board (400) into the connector (300) may be easier than separation of the flexible circuit board (400) from the connector (300).

FIG. 10 is an operation showing the movement of the first terminal (310) and the second terminal (320) according to one embodiment of the present disclosure.

FIG. 10 may be a drawing showing a state in which an ending portion (FP1, see FIG. 8) of a flexible circuit board (400) is separated from a connector (300) or connected to a connector (300).

The pre-connection state (1001) of FIG. 10 may represent the connector (300) before the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is connected to the connector (300). The post-connection state (1002) of FIG. 10 may represent the connector (300) after the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is connected to the connector (300).

In one embodiment, the first terminal (310) may be positioned so that the first contact point (311) is spaced apart from the circuit board (500) by a first height (H1) when the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is connected to the connector (300) (e.g., after connection state (1002)).

In one embodiment, the first terminal (310) may be positioned so that the first contact point (311) is spaced apart from the circuit board (500) by a second height (H2) different from the first height (H1) when the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is separated from the connector (300) (e.g., the pre-mating state (1001)).

In one embodiment, the second terminal (320) may be positioned so that the second contact point (321) is spaced apart from the circuit board (500) by a third height (H3) when the ending portion (FP1) of the flexible circuit board (400) is connected to the connector (300) (e.g., after connection state (1002)).

In one embodiment, the second terminal (320) may be positioned so that the second contact point (321) is spaced apart from the circuit board (500) by a fourth height (H4) that is different from the third height (H3) when the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is separated from the connector (300) (e.g., the pre-mating state (1001)).

In one embodiment, the first difference between the first height (H1) and the second height (H2) may be greater than the second difference between the third height (H3) and the fourth height (H4).

In one embodiment, a flexible circuit board (400) is coupled to a connector (300), and at least a portion of a first terminal (310) and at least a portion of a second terminal (320) can be moved. For example, the flexible circuit board (400) can be inserted into the connector (300), and the first terminal (310) can be pushed in the positive Z-axis direction, and the second terminal (320) can be pushed in the negative Z-axis direction.

Referring to FIG. 10, when the flexible circuit board (400) is connected to the connector (300), at least a portion of the first terminal (310) can be moved by a first deformation amount (D1). For example, the first contact point (311) of the first terminal (310) can be moved in the positive Z-axis direction by a first deformation amount (D1).

Referring to FIG. 10, when the flexible circuit board (400) is connected to the connector (300), at least a portion of the second terminal (320) can be moved by a second deformation amount (D2). For example, the second contact point (321) of the first terminal (320) can be moved in the negative Z-axis direction by a second deformation amount (D2).

In one embodiment, the first deformation amount (D1) may be formed to be greater than the second deformation amount (D2). For example, the first deformation amount (D1) may be approximately 0.07 mm, and the second deformation amount (D2) may be approximately 0.06 mm. When the first deformation amount (D1) is greater than the second deformation amount (D2), the first pressure (F1, see FIG. 7) may be formed to be greater than the second pressure (F2, see FIG. 7).

In one embodiment, after the flexible circuit board (400) is connected to the connector (300), the degree to which the first terminal (310) and/or the second terminal (320) is deformed may be within a predetermined range. For example, after the flexible circuit board (400) is connected to the connector (300), the degree to which the first terminal (310) and/or the second terminal (320) is deformed in the height direction (e.g., Z-axis direction) of the connector (300) may be formed to be approximately 20% or less of the first deformation amount (D1) or the second deformation amount (D2).

FIG. 11a and FIG. 11b are drawings showing a stopper (335) of a connector (300) according to one embodiment of the present disclosure.

FIG. 11a is a drawing showing a state in which a flexible circuit board (400) according to one embodiment is at least partially in contact with a stopper (335). FIG. 11b is a drawing showing a state in which a flexible circuit board (400) according to one embodiment is spaced apart from a stopper (335).

Referring to FIG. 11A, the connector housing (330) may include a catch (331) including a protruding area (3315) protruding from the lower surface (337A) of the hollow (337) toward the upper surface (337B) adjacent to the housing opening (333).

In one embodiment, the lower surface (337A) of the hollow (337) may be a surface that surrounds the hollow (337) and is positioned in the negative Z-axis direction with respect to the hollow (337). The upper surface (337B) of the hollow (337) may be a surface that surrounds the hollow (337) and is positioned in the positive Z-axis direction with respect to the hollow (337).

In one embodiment, the side wall (337C) of the hollow (337) may be a wall positioned in the positive Y-axis direction with respect to the hollow (337). The side wall (337C) of the hollow (337) may face the first side wall (330A) of the connector housing (330).

Referring to FIGS. 11a and 11b, the connector housing (330) may include a stopper (335) at least in a portion thereof.

In one embodiment, the stopper (335) may be composed of a different material than the first side wall (330A) of the connector housing (330).

In one embodiment, the stopper (335) may be configured to support the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) in a direction toward the housing opening (333) when the ending portion (FP1, see FIG. 8) of the flexible circuit board (400) is engaged with the connector (300).

In one embodiment, the stopper (335) may serve to prevent or reduce the insertion of the flexible circuit board (400) beyond a predetermined standard into the connector (300).

In one embodiment, the stopper (335) may include a surface formed substantially perpendicular to the width direction (e.g., Y-axis direction) of the connector (300). In one embodiment, the stopper (335) may include a surface formed substantially perpendicular to the direction in which the flexible circuit board is inserted (e.g., Y-axis direction).

Referring to FIG. 11A, when the flexible circuit board (400) is fully inserted into the connector (300), the flexible circuit board (400) can at least partially contact the stopper (335). When the flexible circuit board (400) is fully inserted into the connector (300), the protrusion (405) of the flexible circuit board (400) can be spaced apart from the catch (331) of the connector housing (330) by a first distance (G1). In one embodiment, the first distance (G1) can be approximately 0.5 mm to 0.15 mm.

In one embodiment, an assembler who attaches a flexible circuit board (400) to a connector (300) can detect contact between the flexible circuit board (400) and the stopper (335) to ensure that the flexible circuit board (400) is maximally inserted into the connector (300). That is, an assembler who attaches a flexible circuit board (400) to a connector (300) can prevent or reduce the flexible circuit board (400) from being inserted into the connector (300) below a predetermined standard by inserting the flexible circuit board (400) into the connector (300) until the flexible circuit board (400) and the stopper (335) make at least partial contact.

In one embodiment, the stopper (335) may serve to prevent the flexible circuit board (400) from being inserted into the connector (300) beyond a predetermined standard. For example, when the flexible circuit board (400) is fully inserted into the connector (300), the flexible circuit board (400) comes into at least partial contact with the stopper (335) and can no longer be inserted into the connector (300), thereby preventing or reducing the flexible circuit board (400) from being inserted into the connector (300) beyond a predetermined standard.

FIG. 11b may be a drawing showing a state in which the flexible circuit board (400) is moved after the flexible circuit board (400) is connected to the connector (300) so that the flexible circuit board (400) is spaced as much as possible from the stopper (335).

Referring to FIG. 11b, when the flexible circuit board (400) is connected to the connector (300), the flexible circuit board (400) may be moved so that the flexible circuit board (400) may be spaced apart from the stopper (335) by a second distance (G2). In one embodiment, the second distance (G2) may be a distance when the flexible circuit board (400) is spaced apart from the stopper (335) to the maximum extent while the flexible circuit board (400) is inserted into the connector (300).

In one embodiment, the third distance (G3) may be the distance between the second contact point (321) of the second terminal (320) and the stopper (335). The fourth distance (G4) may be the distance from the end of the flexible circuit board (400) to a portion where a pad of the flexible circuit board (400) (e.g., a portion electrically connected to the plating layer (415, 475, see FIG. 5)) is formed.

In one embodiment, the fifth distance (G5) may be the length of a portion where the flexible circuit board (400) and a terminal (e.g., the second terminal (320)) can be in effective contact. The longer the fifth distance (G5) is, the more advantageous it is for the second terminal (320) and the flexible circuit board (400) to be electrically connected.

In one embodiment, the fifth distance (G5) can be calculated based on [Mathematical Formula 1].

[Mathematical Formula 1]

G5=G3-G4-G2

In one embodiment, even if the flexible circuit board (400) is spaced apart from the stopper (335) by a maximum of the second distance (G2), the fifth distance (G5) is maintained above a predetermined standard so that contact and electrical connection between the flexible circuit board (400) and the second terminal (320) can be maintained. For example, in one embodiment, the second distance (G2) may be approximately 0.1 mm. The third distance (G3) may be approximately 0.45 mm. The fourth distance (G4) may be approximately 0.15 mm. In this case, the fifth distance (G5) calculated based on [Mathematical Formula 1] may be approximately 0.20 mm.

In one embodiment, the second contact point (321) of the second terminal (320) may be spaced apart from the side wall (337C) of the hollow (337) by a third distance (G3). In one embodiment, the third distance (G3) may be approximately 0.40 to 0.50 mm.

Referring to FIG. 11b, the first terminal (310) can be placed in the connector housing (330) such that the second contact point (321) of the second terminal (320) is located between the first contact point (311) of the first terminal (310) and the side wall (337C) of the hollow (337).

FIG. 12a and FIG. 12b are exploded perspective views of a connector (300) according to one embodiment of the present disclosure.

In one embodiment, the width of the first fitting region (315) may be a length that the first fitting region (315) extends in the longitudinal direction (e.g., X-axis direction) of the connector housing (330). Referring to FIG. 13b, the width of the first fitting region (315) may be a first width (WD1).

Figures 15a and 15b are drawings showing the pitches (P0, P1, P2) between the first terminals (1510, 1610).

FIG. 15A is a diagram showing a comparative pitch (P0) between first terminals (1510) of a connector (1500) according to a comparative embodiment. FIG. 15B is a diagram showing a first pitch (P1) between first terminals (1610) and a second pitch (P2) between second terminals (1620) of a connector (1600) according to an embodiment of the present disclosure.

In describing a connector (1500, 1600) according to one embodiment of the present disclosure, the longitudinal direction of the connector (1500, 1600) may mean the X-axis direction, and the width direction of the connector (1500, 1600) may mean the Y-axis direction. The height direction of the connector (1500, 1600) may mean the Z-axis direction perpendicular to the longitudinal direction and the width direction.

Referring to FIG. 15A, a connector (1500) according to a comparative embodiment may include a first terminal (1510), a second terminal (1520), and/or a connector housing (1530).

In a comparative embodiment, a plurality of first terminals (1510) may be spaced apart in the longitudinal direction (e.g., X-axis direction) of the connector (1500). A plurality of second terminals (1520) may be spaced apart in the longitudinal direction (e.g., X-axis direction) of the connector (1500).

In a comparative embodiment, the first terminal (1510) and the second terminal (1520) may be arranged with a spacing distance (k) in the longitudinal direction (e.g., X-axis direction) of the connector (1500). The spacing distance (k) may be approximately 0.175 mm.

In a comparative embodiment, the pitch between the plurality of first terminals (1510) may be formed as a comparative pitch (P0). The comparative pitch (P0) may be formed as twice the separation distance (k). The comparative pitch (P0) may be approximately 0.35 mm.

In the comparative embodiment, the first terminal (1510) and the second terminal (1520) may not be aligned with each other. The first terminal (1510) and the second terminal (1520) may be arranged at different positions with respect to the longitudinal direction (e.g., X-axis direction) of the connector (1500). For example, in the connector (1500) according to the comparative embodiment, the first terminal (1510) and the second terminal (1520) need to be arranged at different positions with respect to the longitudinal direction (e.g., X-axis direction) of the connector (1500) since they must be in contact with the same surface of the flexible circuit board (e.g., 400, see FIG. 4). That is, in the connector (1500) according to the comparative embodiment, the first terminal (1510) and the second terminal (1520) cannot be arranged at overlapping positions, so there may be a limit to reducing the pitch between the terminals (1510, 1520).

Referring to FIG. 15b, a connector (1600) according to one embodiment of the present disclosure may include a first terminal (1610), a second terminal (1620), and/or a connector housing (1630).

Referring to FIG. 15b, a connector (1600) according to one embodiment may include a first terminal (1610), a second terminal (1620), and/or a connector housing (1630).

In one embodiment, a plurality of first terminals (1610) may be spaced apart in the longitudinal direction (e.g., X-axis direction) of the connector (1600). A plurality of second terminals (1620) may be spaced apart in the longitudinal direction (e.g., X-axis direction) of the connector (1600).

In one embodiment, the pitch between the plurality of first terminals (1610) may be formed as a first pitch (P1). The first pitch (P1) may be approximately 0.30 mm or less. The first pitch (P1) may be smaller than the comparative pitch (P0).

In one embodiment, the pitch between the plurality of second terminals (1620) may be formed as a second pitch (P2). The second pitch (P2) may be approximately 0.30 mm or less. The second pitch (P2) may be smaller than the comparative pitch (P0).

In one embodiment, the first terminal (1610) and the second terminal (1620) may be arranged to be aligned. The first terminal (1610) and the second terminal (1620) may be arranged at substantially the same position relative to the longitudinal direction (e.g., X-axis direction) of the connector (1600). For example, in the connector (1600) according to one embodiment of the present disclosure, the first terminal (1610) and the second terminal (1620) may be arranged at positions that are aligned with each other relative to the longitudinal direction (e.g., X-axis direction) of the connector (1500) since they may contact different surfaces of a flexible circuit board (e.g., 400, see FIG. 4).

According to one embodiment of the present disclosure, a connector (1600) may have a first terminal (1610) and a second terminal (1620) that may be brought into contact with different surfaces of a flexible circuit board (400, see FIG. 6). That is, in the connector (1600) according to one embodiment, the first terminal (1610) may be brought into contact with a first surface (400A, see FIG. 6) of the flexible circuit board (400, see FIG. 6), and the second terminal (1620) may be brought into contact with a second surface (400B, see FIG. 6) of the flexible circuit board (400, see FIG. 6). According to one embodiment of the present disclosure, the connector (1600) has terminals (1610, 1620) that contact both sides (400A, 400B, see FIG. 6) of a flexible circuit board (400, see FIG. 6), so that the pitch (P2) between the terminals (1610, 1620) can be reduced compared to the connector (1500) according to the comparative embodiment.

FIG. 16 is a drawing showing a connector (1600) according to one embodiment of the present disclosure.

A connector (1600) according to one embodiment of the present disclosure may include a first terminal (1610), a second terminal (1620), and/or a connector housing (1630).

A connector (1600) according to one embodiment of the present disclosure may have a first width (W) in the width direction (e.g., Y-axis direction) of the connector (1600). For example, a distance from an end of a first terminal (1610) to a second terminal (1620) in the width direction (e.g., Y-axis direction) of the connector (1600) may be the first width (W).

Since the connector (1600) according to one embodiment of the present disclosure does not require a separate device (not shown) for coupling the flexible circuit board (400, see FIG. 6) and the connector (1600), the width direction (e.g., Y-axis direction) length of the connector (1600) can be reduced. For example, if a separate device (not shown) is required for coupling the flexible circuit board (400, see FIG. 6) and the connector (1600), the width direction (e.g., Y-axis direction) length of the connector (1600) corresponding to the first width (W) can be approximately 3.2 mm, but since the connector (1600) according to one embodiment of the present disclosure does not require a separate device (not shown), the first width (W) can be formed to be approximately 2.3 mm.

Since a connector (1600) according to one embodiment of the present disclosure does not require a separate device (not shown) for joining a flexible circuit board (400, see FIG. 6) and the connector (1600), the cost and time required for manufacturing a separate device (not shown) can be reduced.

FIG. 17 is a drawing showing a connector (1700) and a flexible circuit board (1800) according to one embodiment of the present disclosure.

The connector (1700) of FIG. 17 may refer to the connector (300) of FIG. 3a or may include at least a portion of the connector (300).

The flexible circuit board (1800) of FIG. 17 may refer to the flexible circuit board (400) of FIG. 4 or may include at least a portion of the flexible circuit board (400).

In one embodiment, the connector (1700) may include a first terminal (1710), a second terminal (1720), and/or a connector housing (1730).

In one embodiment, the flexible circuit board (1800) may include a first layer (1810), a second layer (1820), and/or a third layer (1830).

In one embodiment, the first layer (1810) and the second layer (1820) may be layers comprising a conductive material. The third layer (1830) may be a layer comprising an insulating material.

In one embodiment, the first layer (1810) may be disposed on one side of the third layer (1830) (e.g., the side facing the positive Z-axis direction in the third layer (1830)). The second layer (1820) may be disposed on the other side of the third layer (1830) (e.g., the side facing the negative Z-axis direction in the third layer (1830)).

In one embodiment, a first terminal (1710) of a connector (1700) can make at least partial contact with a first layer (1810) of a flexible circuit board (1800). A second terminal (1720) of a connector (1700) can make at least partial contact with a second layer (1820) of a flexible circuit board (1800).

In a flexible circuit board (1800) according to one embodiment of the present disclosure, a first terminal (1710) of a connector (1700) is electrically connected by at least a portion of contacting a pad formed on a first layer (1810), and a second terminal (1720) of the connector (1700) is electrically connected by at least a portion of contacting a pad formed on a second layer (1820), so that a via for electrically connecting the first layer (1810) and the second layer (1820) may not be required. That is, in a circuit board (1800) according to one embodiment of the present disclosure, a via may not be required because the circuit board (1800) is in contact with the first terminal (1710) or the second terminal (1720) of the connector (1700) on both sides of the circuit board (1800), respectively. According to one embodiment of the present disclosure, a flexible circuit board (1800) can reduce the cost and time required for manufacturing vias by reducing the number of vias for electrically connecting the first layer (1810) and the second layer (1820).

According to one embodiment of the present disclosure, the flexible circuit board (1800) is in contact with the terminals (1710, 1720) of the connector (1700) in the first layer (1810) and the second layer (1820), so that the pitch between pads (not shown) formed on the flexible circuit board (1800) can be relatively increased. That is, the flexible circuit board (1800) can be advantageous in increasing the pitch between pads (not shown) formed on the flexible circuit board (1800) compared to a case where the flexible circuit board (1800) is in contact with the connector on one side.

If the terminals of the connector are only in contact with one side of the flexible circuit board, the flexible circuit board may need to include vias to electrically connect at least some of the terminals of the connector to the other side of the flexible circuit board, which is the opposite side of the one side. If the flexible circuit board needs to include vias, additional manufacturing costs and time may be required to form the vias.

If the flexible circuit board does not include vias, the connector's terminals are in contact only on one side of the flexible circuit board, and it is difficult to reduce the pitch between the terminals, so the overall size of the connector may increase.

An electronic device (101, 200) according to one embodiment of the present disclosure comprises a flexible circuit board (240, 400), a circuit board (220, 500), and a connector (250, 300) disposed on the circuit board (220, 500) and configured to be connected or disconnected from an ending portion (FP1) of the flexible circuit board (240, 400), wherein the connector (250, 300) comprises a connector housing (330) including a hollow (337) formed therein, a first terminal (310) extending from the circuit board (500) into the hollow (337) and configured to apply a first pressure (F1) in a first direction through its first contact point (311), and a second terminal (310) extending from the circuit board (500) into the hollow (337) and configured to apply a second pressure (F2) in a second direction opposite to the first direction through its second contact point (321).
