Description

Connector {CONNECTOR}

The present invention relates to a connector having a bayonet-type structure for switching a locked state and an unlocked state between a pair of connectors with a weak operation force.

A connector having a bayonet-type structure for switching between a locked state and an unlocked state between a pair of connectors with a weak operation force is conventionally known (see Patent Document 1).

As an example of such a conventional connector, the male connector 100 shown in Figs. 1 to 4 includes a male connector housing 110 and a male connector 110 in a rotatable manner between a lock start position and a lock end position of the connector. And a bayonet-shaped ring (rotating member) 120 attached to the housing 110.

The male connector housing 110 is provided with a plurality of terminal chambers 111 for accommodating male terminals (not shown) therein. The male connector housing 110 is provided at its rear edge with a first position adjusting wall 112 and a second position adjusting wall 113 protruding outwardly. The first locking wall surface 112a and the second locking wall surface 112b are formed on both sides of the first position adjusting wall 112 vertically, respectively.

The bayonet ring 120 has a plurality of cam protrusions 121 formed on the inner wall adjacent to the front edge of the bayonet ring 120. The cam protrusion 121 can be engaged with the cam groove 202 provided in the female connector housing 201 of the mated female connector 200. [ The bayonet shaped ring 120 is provided with a locking arm 123 which is bent by a cantilever structure and can be provided with a locking claw 122 and an excessive rotation adjusting projection 124 at the rear edge. The lock claw 122 sequentially contacts the second position adjusting wall 113 and the first position adjusting wall 112 of the male connector housing 110 when the bayonet ring 120 is rotated in the unlocking direction And has a locking surface 122a. The locking surface 122a is curved toward the outside.

When the bayonet-shaped ring 120 is positioned at the lock end position, the second position restricting wall 113 locks the lock claw 122 as shown in Fig. 4 (a). When the bayonet ring 120 is rotated in the unlocking direction, the second position adjusting wall 113 comes into contact with the locking surface 122a of the locking claw 122, So that the arm 123 is bent. The second position adjusting wall 113 is then allowed to pass over the locking claw 122.

In the above-described configuration, the male terminal is housed in the terminal chamber 111 of the male connector 100, and the female terminal is housed in the terminal chamber (not shown) of the female connector 200 in a mated form. The male connector housing 110 positions the cam protrusion 121 at the entrance of the cam groove 202 and subsequently rotates the bayonet ring 120 from the lock start position to the lock end position And is fixed to the lock-start position with respect to the female connector housing 201 in a manner as described above. Due to the bending of the lock arm 123, the lock claw 122 sequentially moves the first position adjusting wall 112 and the second position adjusting wall 122 in order, so that the lock pin 122 is moved to the lock end position. (113). As a result, as shown in FIGS. 5 and 6, the second position restoring wall 113 regulates the rotation of the lock claw 122 to maintain the lock claw 122. The male connector housing 110 and the female connector housing 201 move to the lock end position and the cam protrusion 121 of the male connector housing 110 moves to the female connector housing 201 As shown in FIG. Thus, the male connector 100 is locked with the female connector 200 so that the male terminal electrically connects to the female terminal.

When the bayonet ring 120 is rotated from the lock end position to the lock start position (i.e., in the unlocking direction), the lock claw 122 is moved to the second position restricting wall 113 And the first position adjusting wall 112, and moves to the lock start position. As a result, the male connector housing 110 and the female connector housing 201 move to the lock start position. At this point, the first position adjusting wall 112 regulates the rotation of the lock claw 122 to maintain the lock claw 122.

Since the connector is used in a strong vibration state or the like, the connector according to the conventional example is required to more stably maintain the bail-type ring 120 at the lock end position shown in Figs.

US 6811423 B2

The male connector 100 of the conventional example is provided with a locking surface 122a curved outward to come into contact with the second position adjusting wall 113. [ Since the locking claw 122 is biased by the repulsive force applied to the locking surface 122a from the second position adjusting wall 113, the locking claw 122 easily moves in the unlocking direction. Further, as shown in Figs. 4 (a) and 4 (b), when the lock arm 123 is in the unbent state, the locking surface 122a of the second position adjusting wall 113 The inclination angle I is almost equal to the inclination angle J of the lock surface 122a in which the lock arm 123 is bent. This also allows the locking claw 122 to easily move in the unlocking direction. This easy movement limits the ability to maintain the bayonet ring 120 in the lock termination position.

An increase in the inclination angle of the lock surface 122a allows the bayonet ring 120 to be held more stably at the lock end position. However, when the inclination angle of the lock surface 122a excessively increases, for example, when the inclination angle increases at a right angle, the possibility that the lock arm 123 is damaged increases.

The present invention has been made in view of the above problems. An object of the present invention is to provide a connector capable of preventing damage to a lock arm provided on a rotating member and keeping the rotating member more stably at a lock end position.

A connector according to a first aspect of the present invention includes: a connector housing accommodating one or more terminals; A rotary member attached to the connector housing in a rotatable manner between a lock start position and a lock end position of the connector; A locking arm mounted to the rotatable member and including a locking claw having a locking surface, the locking arm side of the locking surface having a surface that is linearly inclined relative to a base of the locking arm, said locking arm comprising a curved surface located at the top of said claw and formed in a curved shape; A first position adjusting wall installed on the connector housing to lock the lock claw when the rotating member is located at the lock start position; And a second position adjusting wall installed on the connector housing to lock the lock claw when the rotating member is positioned at the lock end position. When the rotary member is rotated from the lock start position to the lock end position, with the connector housing fixed to the lock start position with respect to the mated connector housing, the lock claw is caused by the bending of the lock arm Wherein the connector housing and the mating connector housing move to the locking end position in association with the movement of the locking claw as it moves past the first position adjusting wall and the second position adjusting wall to the locking end position, Move. The lock claw crosses the second position adjusting wall and the first position adjusting wall due to the bending of the lock arm when the rotating member is rotated from the lock end position to the lock start position, The connector housing and the mating connector housing move to the lock start position in association with the movement of the locking claw.

Preferably, the lock wall surface of the first position restricting wall, which is in contact with the lock arm when the rotatable member is rotated from the lock end position to the lock start position, is formed in a tapered shape.

In the connector according to the first aspect of the present invention, the locking surface of the locking claw has an inclined surface in contact with the second position adjusting wall when the rotating member is rotated in the unlocking direction from the locking end position. Since the second position adjusting wall presses the edge thereof with the locking surface, it is possible to maintain the rotating member at the locking end position more stably without increasing the inclination angle of the locking surface. Further, due to the inclined surface provided on the lock surface, the inclination angle of the inclined surface is changed so as to increase as the level of the warp of the lock claw increases. This also contributes to keeping the rotating member more stable at the lock end position without increasing the tilt angle, with the lock claw not bent. In addition, the curved surface at the top of the locking surface of the locking claw allows the second positioning wall to smoothly pass over the locking claw, which provides a sense that engagement is complete. When the second position adjusting wall passes over the locking claw, the locking of the locking claw is released so that the second position adjusting wall certainly makes a sound when the locking claw returns to the initial position, which gives the operator a stable unlocking operation ability .

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

7 to 19 illustrate an embodiment of the present embodiment.

As shown in Fig. 7, the connector device 1 includes a male connector 2 functioning as a connector according to the embodiment, and a female connector 3 functioning as a paired connector. The male connector (2) includes a male connector housing (4) and a bayonet ring (5) as a rotating member. The bayonet shaped ring 5 is attached to the male connector housing 4 in such a manner that it rotates between the lock start position and the lock end position of the connector. Here, the lock start position of the connector is the position where the male connector 2 is unlocked with the female connector 3 through the bayonet ring 5. The lock end position of the connector is a position where the male connector 2 is locked with the female connector 3 through the bayonet ring 5.

The male connector housing (4) receives a sealant (6). The front end of the female connector 3 comes into contact with the sealing material 6 when the female connector 3 is locked with the male connector 2. [ The sealing material 6 seals the gap between the male connector 2 and the female connector 3. [

The front holder 41 is attached to the front end of the male connector housing 4. In the interior of the male connector housing 4, a plurality of terminal chambers 44 for accommodating male terminals 43 crimped to the wires 42 are provided, respectively. The rear end of the male connector housing 4 is provided with a first position adjusting wall 45 projecting laterally to lock the locking claw 52 of the locking arm 53 provided on the bayonet- A two-position cladding wall 46 is provided. The rear end of the male connector housing 4 is provided with two excess rotary walls 47 protruding laterally in order to contact the excessive rotation regulating projection 54 of the bayonet ring 5.

14, the first position restricting wall 45 locks the lock claw 52 when the male connector housing 4 and the bayonet-type ring 5 are positioned at the lock start position. Then, the bayonet-shaped ring 5 is located at the lock start position by the first position adjusting wall 45. [ At this point the bayonet shaped ring 5 is positioned in such a way that the cam projection 51 of the bayonet shaped ring 5 is located at the entrance of the cam groove 32 of the female connector 3. As shown in Figs. 15 and 16, the second position adjusting wall 46 locks the lock claw 52 when the male connector housing 4 and the bayonet-like ring 5 are located at the lock end position. Then, the bayonet-shaped ring 5 is located at the lock end position by the second position adjusting wall 46. [

8 (a) and 8 (b), the first position adjusting wall 45 has a first locking wall surface 45a formed in a tapered shape and a second locking wall surface 45b formed vertically, . The lock arm 53 contacts the first lock wall surface 45a when the bayonet-like ring 5 is rotated from the lock end position to the lock start position (i.e., in the unlocking direction). The locking arm 53 is gradually bent along the tapered shape of the first locking wall surface 45a in relation to the relative movement between the locking arm 53 and the first position adjusting wall 45. [

Adjacent to the front end of the outer wall, the bayonet-shaped ring 5 is provided with a rotation support projection 50 projecting inward and positioned at a specific distance in the circumferential direction. The rotary support protrusion 50 enters the circumferential groove 40 provided on the peripheral portion of the male connector housing 4. [ The bayonet shaped ring 5 is rotatably supported by the male connector housing 4 in such a manner that the rotary support projection 50 slides along the circumferential groove 40.

The cam protrusion 51 is provided on the front surface of the inner wall of the bayonet-shaped ring 5. The cam protrusion 51 is engaged with the cam groove 32 provided on the female connector housing 31 of the female connector 3. The rear end of the bayonet-type ring 5 is provided with a lock arm 53, which can be bent by the cantilever structure and includes a lock claw 52, and an excessive rotation adjusting projection 54. [

9 (a) and 9 (b), the locking claw 52 has a first locking surface 55 which is in contact with the first position adjusting wall 45 and the second position adjusting wall 46, And a second locking surface (56). The first locking surface 55 is brought into contact with the first position adjusting wall 45 and the second position adjusting wall 46 when the bayonet ring 5 rotates in the unlocking direction from the locking end position. The first locking surface 55 includes an inclined surface 55a formed linearly on the base side and a curved surface 55b integrated with the inclined surface 55a and positioned adjacent to the top of the first locking surface 55 . The second locking surface 56 is located between the first position adjusting wall 45 and the second position adjusting wall 46 when the bayonet ring 5 rotates from the lock start position to the lock end position / RTI > The second locking surface 56 is elongated vertically.

The female connector housing 31 of the female connector 3 is also provided with a plurality of terminal chambers (not shown) for respectively housing female terminals (not shown).

The terminal chamber 44 of the male connector 2 receives the male terminal 43 and the terminal chamber of the female connector 3 receives the female terminal. The male connector housing 4 is fixed at the lock start position with respect to the female connector housing 31 in such a manner that the cam protrusion 51 is located at the entrance of the cam groove 32. [

The bayonet ring 5 rotates from the lock start position to the lock end position (clockwise direction indicated by the arrow in Fig. 14, i.e., in the lock direction). The locking claw 52 sequentially passes across the first position adjusting wall 45 and the second position adjusting wall 46 due to the warping of the locking arm 53, Position. As shown in FIG. 15, the second position adjusting wall 46 prevents the rotation of the lock claw 52 to hold the lock claw 52. In addition, the male connector housing 4 and the female connector housing 31 move to the lock end position in association with the movement of the lock claw 52. The cam protrusion 51 of the male connector housing 4 moves along the cam groove 32 of the female connector housing 31. As a result, the male connector 2 is locked with the female connector 3, and the male terminal 43 is thus electrically connected to the female terminal.

When the bayonet-type ring 5 is rotated from the lock end position to the lock start position (in the counterclockwise direction indicated by the arrow in Fig. 15, i.e., in the unlocking direction) The locking claw 52 is then engaged with the second position adjusting wall 46 as shown in Fig. 19 (b) Passes through the cliff 46, and passes through the second locating wall 46 as shown in Figure 19 (c). The locking claw 52 further crosses the first position adjusting wall 45 and thereby moves to the lock starting position. As a result, the male connector housing 4 and the female connector housing 31 move to the lock start position. 14, the first position restricting wall 45 prevents rotation of the lock claw 52 of the lock arm 53 in order to hold the lock claw 52. As shown in Fig.

According to the embodiment, for example, when the bead-shaped ring 5 positioned at the lock end position due to vibration during driving the vehicle rotates in the unlocking direction, the inclined surface 55a located at the base side of the lock collector 52 Contacts the second position regulating wall 46 as shown in Fig. 18 (b). The edge 46a of the second position adjusting wall 46 is engaged with the inclined surface 55 of the lock claw 52 as shown in Fig. 18 (c) because the inclined surface 55a is linearly formed (bite). Therefore, the bayonet-type ring 5 can be stably maintained at the lock end position without increasing the inclination angle of the inclined surface 55a. In addition, since the inclined surface 55a of the locking surface 55 is linear, the inclination angle of the inclined surface 55a varies with increasing level of the warp of the locking claw 52. [ 18 (b) and 18 (d), when the inclination angle F of the inclined surface 55a in the moving direction of the second position regulating wall 46 in the state where the lock arm 53 is bent is F , The inclination angle D of the inclined surface 55a when the lock arm 53 is not bent is larger. This configuration allows the bayonet ring 5 to stably maintain the bayonet-shaped ring 5 at the lock end position without increasing the inclination angle in a state where the lock claw 52 is not bent.

According to an embodiment, the curved surface 55b is located at the top of the locking surface 55 of the locking claw 52. [ The second position adjusting wall 46 can therefore smoothly pass over the locking claw 52 as shown in Figure 19 (b), which provides a sense that the engagement is complete. Further, when the second position adjusting wall 46 passes over the locking claw 52, the second position adjusting wall 46 is released from the warping of the locking claw 52, c sound certainly when returning to the initial position, as shown in c), which provides the operator with a stable unlocking capability of the connector.

According to the embodiment, since the first locking wall surface 45a of the first position restricting wall 45 is formed in a tapered shape, the bayonet-type ring 5 is locked by the lock arm 53 in the locking claw 52 A lock located at a position between the first position adjusting wall 45 and the second position changing wall 46 in such a manner that the inclined surface 55a gradually bends while moving along the tapered first locking wall surface 45a When the arm 53 moves to return to the lock start position, it can easily rotate. Therefore, the bayonet-type ring 5 can be smoothly rotated as compared with the case where the lock wall surface of the first position adjusting wall is vertically formed as in the case of the conventional example (Patent Document 1: US 6811423 B2).

According to the embodiment, the locking surface of the locking claw 52 is configured such that the curved surface (the locking surface of the conventional locking claw) indicated by the two-dot chain line shown in Figure 18 (a) To the inclined surface 55a indicated by the solid line shown in Fig. Therefore, the embodiment can be implemented by finely changing the conventional die. Here, the spring constant of the lock arm 53 can be increased to maintain the bayonet-type ring 5 more stably. However, in such a case, many modifications of the conventional die may be required. Therefore, changing the shape of the lock surface of the lock claw 52 as in the case of this embodiment can be a low-cost method as compared with increasing the spring constant of the lock arm of the conventional example.

According to the embodiment, the lock surface of the lock claw 52 is also formed by the two-dot chain line shown in Fig. 18 (a) so that the lock surface of the lock claw of the conventional example is inclined at the inclination indicated by the solid line in Fig. And cut along the surface 55a. Since only a simple process may be required for the conventional example, the conventional example can be effectively utilized.

The present invention provides a connector capable of preventing damage to a lock arm provided on a rotating member and holding the rotating member in a locking end position of the connector more stably.
