Description

Electric connector plug

The present invention relates to an electrical connector plug, in particular to an electrical connector plug configured to be docked with a portable electric energy storage device.

It is known that batteries (such as lithium ion batteries) are used to store more energy in smaller, lighter cells. Lithium-ion batteries have been widely used to power portable electronic devices (for example, mobile phones, tablet computers, laptop computers, power tools, and other high-current devices). The characteristics of low weight and high energy density also make lithium-ion batteries attractive for use in hybrid electric vehicles and fully electric vehicles.

For example, the car-end connector on an electric vehicle adopts a male connector, and the battery-end connector of the battery mated with it adopts a female connector. Since the current passing through is larger than that of ordinary electronic products, a crown spring is usually provided on the inner side of the female connector of the battery terminal connector to strengthen its electrical connection. After a considerable number of insertions and removals of the crown spring, it may cause wear or displacement (for example, longitudinal wear). In order to maintain the electrical connectivity of the battery terminal connector, the aforementioned wear or displacement needs to be effectively controlled. However, after long-term use of the electric vehicle, the crown spring may cause wear or displacement (for example, lateral wear) on the connector at the contact point due to the compression of the vibration. Since there are different suppliers of connectors and crown springs, the tolerances allowed on the dimensions are different, and the materials used in the crown springs are also different (for example, the alloy ratio is different), which may cause unexpected serious wear. Eventually, it will cause the problem of power or signal transmission interruption due to the momentary non-contact of the connector during use.

Therefore, how to propose a connector that can solve the above problems is one of the problems that the industry urgently wants to invest in research and development resources to solve.

In view of this, one object of the present invention is to provide an electrical connector plug that can effectively solve the aforementioned problems.

In order to achieve the above objective, according to one embodiment of the present invention, an electrical connector plug includes a conductive terminal and an elastic conductive member. The conductive terminal protrudes from one end of the main body and has a groove. The groove extends substantially along an axial direction. The elastic conductive member is arranged in the groove and is configured to produce a length change in the axial direction when a force is applied.

In one or more embodiments of the present invention, the elastic conductive member is a compression spring.

In one or more embodiments of the present invention, the electrical connector plug further includes a conductive fixing member. The conductive fixing part is located in the groove and has a threaded part. A part of the compression spring is screwed with the threaded part.

In one or more embodiments of the present invention, the conductive fixing member is locked with the conductive terminal in the groove.

In one or more embodiments of the present invention, the pitch of the compression spring gradually increases from one end of the compression spring toward the center of the compression spring.

In one or more embodiments of the present invention, the electrical connector plug further includes an elastic connector. The elastic connector is arranged around the inner wall of the groove.

In one or more embodiments of the present invention, the elastic connector is closer to the entrance of the groove than the elastic conductive member.

In one or more embodiments of the present invention, the elastic connector has two contact points. The two contact points are respectively located on two virtual planes perpendicular to the axial direction.

In one or more embodiments of the present invention, the two contact points are arranged in the axial direction.

In one or more embodiments of the present invention, the elastic connector includes two bars. The two contact points are respectively located on the two grid bars.

In one or more embodiments of the present invention, the two bars are aligned in the axial direction.

In one or more embodiments of the present invention, at least one of the two bars is a cantilever structure.

In one or more embodiments of the present invention, the lengths of the two bars in the axial direction are different.

In one or more embodiments of the present invention, the elastic conductive member is located at the bottom of the groove.

In summary, in the electrical connector plug of the present invention, the elastic conductive member arranged in the groove of the conductive terminal can be contacted and squeezed by one end of the test terminal when the test terminal is inserted into the groove, and can be squeezed During the pressing period, the contact with the test terminal is continuously maintained, so it can be used as a stable transmission path for transmitting electrical signals between the conductive terminal and the test terminal. In addition, in the electrical connector plug of the present invention, the elastic connector arranged in the groove of the conductive terminal has a plurality of contact points configured to contact the periphery of the test terminal, so it can also be used as a transmission between the conductive terminal and the test terminal The transmission path of the electrical signal. In particular, these contact points are respectively located on a plurality of virtual planes perpendicular to the extending axis of the groove, so the wear area on the test terminal can be effectively dispersed after the test terminal has been inserted and removed a considerable number of times with respect to the groove. Thereby extending the life of the test terminal.

This multi-directional electrical connection system can form electrical connections in a plurality of rotational orientations.

Please refer to Figure 2 and Figure 3. FIG. 2 is a perspective view showing the electrical connector 120 included in the portable electric energy storage device according to an embodiment of the present invention. FIG. 3 is a perspective cross-sectional view of the electrical connector 120 in FIG. 2 along the line 3-3. As shown in Figures 2 and 3, in this embodiment, the electrical connector 120 includes a non-conductive connector base 121, a first conductive terminal 122, a second conductive terminal 123, an electrical connection test terminal 125, and an elastic connector 127.

The non-conductive connector base 121 includes a conductive base outer wall 121a. When viewed along the axial direction A, the non-conductive connector base 121 has a circular shape. The non-conductive connector base 121 including the outer wall 121a of the conductive base may be formed of a non-conductive material (such as plastic).

The electrical contact housing 126 may be formed of a non-conductive material (for example, non-conductive plastic). In the illustrated embodiment, the electrical contact housing 126 and the non-conductive connector base 121 are two parts of a single structure. However, in practical applications, the conductor base outer wall 121a and the electrical contact housing 126 can also be formed separately and attached to each other.

In the exemplary embodiment shown in FIG. 3, when viewed along the axial direction A, the cross section of the annular electrical contact housing 126 is circular, but the present invention is not limited to this. The cross section of the annular electrical contact housing 126 may also be a non-circular polygonal shape. The inner surface 126 a of the electrical contact housing 126 is positioned closer to the axial direction A than the outer surface 126 b of the electrical contact housing 126. The outer surface 126b of the electrical contact housing 126 and the inner wall 121b of the conductive base can be separated by a non-conductive medium (such as air or other non-conductive medium such as non-conductive plastic).

The first conductive terminal 122 is disposed on the inner surface 126 a of the electrical contact housing 126. In the illustrated exemplary embodiment, the first conductive terminal 122 is a ring-shaped component that conforms to the shape of the inner surface 126 a of the electrical contact housing 126. The first conductive terminal 122 is in electrical contact with the elastic connector 127. The elastic connector 127 is a spring-like member that can be compressed in a transverse direction perpendicular to the axial direction A. The compression characteristic of the elastic connector 127 allows the electrical connector plug 200 to be inserted into the electrical connector 120 and achieve a low resistance electrical connection between the first conductive terminal 122 and the first conductive terminal 213 of the electrical connector plug 200. The elastic connector 127 is conductive and has low resistance. In addition, the elastic connector 127 has the ability to resist corrosion or other degradation that can negatively affect its conductivity and/or electrical resistance. In the illustrated embodiment, the elastic connector 127 uses a crown spring as a specific embodiment, but the invention is not limited to this.

In the illustrated embodiment, the first conductive terminal 122 is electrically connected to the first terminal connector 128 at its base. The first terminal connector 128 is electrically connected to the portable electrical energy storage device, and is configured to provide electrical connection between the portable electrical energy storage device and the first conductive terminal 122.

The second conductive terminal 123 is disposed on the outer surface 126 b of the electrical contact housing 126. In the illustrated exemplary embodiment, the second conductive terminal 123 is a ring-shaped component that conforms to the shape of the outer surface 126 b of the electrical contact housing 126. In the exemplary embodiment shown in FIG. 3, when viewed along the axial direction A, the cross section of the second conductive terminal 123 has a ring shape. The second conductive terminal 123 is electrically connected to the second terminal connector 129 at its base. The second terminal connector 129 is electrically connected to the portable electrical energy storage device, and is configured to provide an electrical connection between the portable electrical energy storage device and the second conductive terminal 123. To avoid obscuring the subject matter described herein, the details of how the first terminal connector 128 and the second terminal connector 129 are electrically connected to the portable electric energy storage device are omitted. In the illustrated embodiment, the tops of the first conductive terminal 122 and the second conductive terminal 123 are bridged by a non-conductive cap 124.

In the exemplary embodiment depicted in FIG. 3, the electrical connection test terminal 125 of the electrical connector 120 is a cylindrical conductive member centered on the axial direction A and extending along the axial direction A. The electrical connection test terminal 125 is positioned radially inside the first conductive terminal 122. The upper surface of the electrical connection test terminal 125 is recessed to the bottom of the outer wall 121a of the conductor base, the electrical contact housing 126, the first conductive terminal 122 and the second conductive terminal 123. The electrical connection test terminal 125 is electrically connected to the connection test terminal connector 130. In the illustrated embodiment, the electrical connection test terminal 125 is electrically connected to the connection test terminal connector 130 at its bottom.

Please refer to Figure 4, Figure 5A and Figure 6. FIG. 4 is a perspective view showing the electrical connector plug 200 included in the electric device according to an embodiment of the present invention. FIG. 5A is a perspective cross-sectional view of the electrical connector plug 200 in FIG. 4 along the line 5A-5A. FIG. 6 is a schematic cross-sectional view of the electrical connector 120 in FIG. 2 and the electrical connector plug 200 in FIG. 4 being inserted. As shown in FIGS. 4, 5A, and 6, in this embodiment, the electrical connector plug 200 includes a non-conductive plug housing 210, a first conductive terminal 213, and a second conductive terminal 214. The first conductive terminal 213 and the second conductive terminal 214 are sized and shaped to fit with the electrical connector 120 and its components. When mated, an electrical connection is formed between the electrical connector 120 and the electrical connector plug 200. In the illustrated embodiment, the second conductive terminal 214 is provided with an elastic connector 220.

The non-conductive plug housing 210 includes a plug body 211. The plug body 211 may include a non-conductive material (such as non-conductive plastic). The plug body 211 has a cylindrical shape and is centered on the axial direction A (for example, the longitudinal axis of the non-conductive plug housing 210). The first conductive terminal 213 and the second conductive terminal 214 protrude from one end of the plug body 211 (the top end in FIG. 4). The first conductive terminal 213 and the second conductive terminal 214 may be formed of a conductive material (for example, a conductive metal). The plug body 211 is at the end where the first conductive terminal 213 and the second conductive terminal 214 protrude, and the ring terminal housing 212 protrudes from the plug body 211 beyond the first conductive terminal 213 and the second conductive terminal 214. In the embodiment shown in FIG. 4, when viewed along the axial direction A, the ring terminal housing 212 has a circular shape, but the present invention is not limited to this. For example, when the shape of the gap between the outer surface 126b of the electrical contact housing 126 and the inner wall 121b of the conductor base of the electrical connector 120 in Figure 3 is other than circular, the ring terminal housing 212 will have a complementary shape. Non-circular shape.

At the other end (the bottom end in FIG. 4) of the ring terminal housing 212 adjacent to the non-conductive plug body 211, the first terminal connector 215 and the second terminal connector 216 protrude from the ring terminal housing 212. In some alternative embodiments, the first terminal connector 215 and the second terminal connector 216 do not protrude from the ring terminal housing 212 but can enter the terminal housing 212. In Figure 5A, the inside of the non-conductive plug body 211 is shown as hollow. According to other embodiments described herein, the non-conductive plug body 211 can be filled with a non-conductive material (for example, non-conductive plastic), and the first terminal connector 215 and the second terminal connector 216 are opposite to the ring shape on the non-conductive plug body 211. One end of the electrical terminal housing 212 extends through the non-conductive material and protrudes from the non-conductive material. The first terminal connector 215 and the second terminal connector 216 provide electrical connectors for forming electrical connections with the first conductive terminal 213 and the second conductive terminal 214, respectively. The first terminal connector 215 and the second terminal connector 216 can be electrically connected to the electric device via two cables (not shown), respectively.

In the embodiments shown in FIGS. 4 and 5A, the first conductive terminal 213 is formed of a conductive material (for example, a conductive metal). When viewed along the axial direction A, the first conductive terminal 213 has a ring shape. The first conductive terminal 213 has a groove 213a. The groove 213a extends substantially along the axial direction A and is configured to be inserted into the electrical connection test terminal 125 of the power supply connector 120. The electrical connector plug 200 further includes an elastic conductive member 217. The elastic conductive member 217 is disposed in the groove 213a, and is configured to contact one end of the power supply connection test terminal 125 to produce a length change in the axial direction A. Thereby, the elastic conductive member 217 can continuously maintain contact with the electrical connection test terminal 125 during the squeezing period, and thus can be used as a stable transmission path for transmitting electrical signals between the first conductive terminal 213 and the electrical connection test terminal 125. In addition, since the elastic conductive member 217 is electrically connected to the axial end of the electrical connection test terminal 125, the peripheral surface of the electrical connection test terminal 125 caused by the continuous insertion and removal of the electrical connector plug 200 is avoided. Possibility to achieve stable electrical connection. In the embodiment shown in FIG. 5A, the elastic conductive member 217 is a compression spring, but the invention is not limited to this. In other embodiments, the elastic conductive member 217 may also be an elastic sheet.

Please refer to FIG. 7, which is a schematic cross-sectional view of the elastic conductive member 217 and the conductive fixing member 218 in FIG. 5A. As shown in FIGS. 6 and 7, in this embodiment, the electrical connector plug 200 further includes a conductive fixing member 218. The conductive fixing member 218 is located in the groove 213a and has a threaded portion 218a. A part of the elastic conductive member 217 is threadedly engaged with the threaded portion 218a. In addition, the conductive fixing member 218 is locked to the first conductive terminal 213 in the groove 213a. With the aforementioned structural configuration, in addition to avoiding the occurrence of the elastic conductive member 217 falling off the groove 213a when the electrical connector plug 200 is plugged in and unplugged, it can also effectively increase the gap between the elastic conductive member 217 and the conductive fixing member 218. The contact area and the contact area between the conductive fixing member 218 and the first conductive terminal 213 further ensure the stability of the electrical signal transmission path formed by the elastic conductive member 217, the conductive fixing member 218 and the first conductive terminal 213.

Please refer to FIG. 8, which is a perspective view of the elastic conductive member 217 in FIG. 7. In the embodiment shown in FIG. 8, the pitch of the elastic conductive member 217 gradually increases from the two ends of the elastic conductive member 217 toward the center of the elastic conductive member 217, thereby increasing the structural stability of the two ends of the elastic conductive member 217. In other embodiments, the elastic conductive member 217 may also be fixed to the first conductive terminal 213 without passing through the conductive fixing member 218 (that is, the conductive fixing member 218 is omitted), and the elastic conductive member 217 is simply placed in the groove 213a. in.

Please refer to FIG. 5B, which is a perspective cross-sectional view of the electrical connector plug 200' in FIG. 4 according to another embodiment of the present invention. As shown in FIG. 5B, in this embodiment, an elastic connector 219 is provided in the groove 213a of the first conductive terminal 213'. Specifically, the elastic connector 219 is arranged around the inner wall of the groove 213a of the first conductive terminal 213', thereby making electrical contact with the first conductive terminal 213'. The elastic connector 219 is a spring-like member that can be compressed in a transverse direction perpendicular to the axial direction A. The elastic connector 219 is configured to contact the periphery of the electrical connection test terminal 125. The diameter and length of the elastic connector 219 are smaller than the elastic connector 127. The compression characteristic of the elastic connector 219 allows the electrical connection test terminal 125 of the electrical connector 120 to be inserted into the groove 213a of the first conductive terminal 213' and a low resistance electrical connection is achieved between the electrical connection test terminal 125 and the first conductive terminal 213'. connection. The other details of the electrical connector plug 200' are the same or similar to those of the electrical connector plug 200. Therefore, reference may be made to the aforementioned related descriptions, which will not be repeated here.

Please refer to FIG. 5C, which is a perspective cross-sectional view of the electrical connector plug 200" in FIG. 4 according to another embodiment of the present invention. As shown in FIG. 5C, in this embodiment, the first conductive terminal 213 The groove 213a is simultaneously provided with the elastic conductive member 217 shown in Figure 5A and the elastic connector 219 shown in Figure 5B. In the embodiment depicted in Figure 5C, the elastic conductive member 217 and the elastic connector 219 are respectively adjacent to the bottom and entrance of the groove 213a, and the elastic connector 219 is closer to the entrance of the groove 213a than the elastic conductive member 217. The other details of the electrical connector plug 200" are the same or similar to the electrical connector plug 200, so you can refer to The aforementioned related descriptions will not be repeated here.

Please refer to Figure 9 and Figure 10. Fig. 9 is a perspective view showing the elastic connector 219 in Fig. 5B and Fig. 5C. Fig. 10 is a schematic partial cross-sectional view showing the structure in Fig. 6; Hereinafter, the structure of the elastic connector 219 will be described in further detail with reference to FIGS. 9 and 10. As shown in FIGS. 9 and 10, in this embodiment, the elastic connector 219 uses a crown spring as a specific example, but the invention is not limited to this. As shown in FIG. 10, the elastic connector 219 has a plurality of contact points, which are configured to contact the periphery of the electrical connection test terminal 125. Taking two contact points 219a1 and 219a2 as an example, the two contact points 219a1 and 219a2 are arranged in the axial direction A and are respectively located on two virtual planes P1 and P2 perpendicular to the axial direction A. Furthermore, in some embodiments, all contact points of the elastic connector 219 are located on a plurality of different virtual planes perpendicular to the axial direction A, respectively. Through the elastic connector 219 of the above structure, the present invention can effectively disperse the wear area on the electrical connection test terminal 125 when the electrical connection test terminal 125 is plugged and unplugged with respect to the groove 213a for a considerable number of times, thereby extending the electrical connection test terminal 125 Life.

Furthermore, please refer to Fig. 9 in conjunction. The elastic connector 219 includes a plurality of bars 219a. In the embodiment shown in FIG. 9, the grid bars 219 a extend substantially along the axial direction A, and each is a cantilever structure. In addition, these grid bars 219a are paired in pairs so that each pair of grid bars 219a are aligned in the axial direction A. Each bar 219a has a contact point. For example, the two contact points 219a1 and 219a2 marked in Figure 10 are respectively located on a pair of grid bars 219a. Specifically, the contact points are respectively located at the ends of the grid bars 219a, so by making the lengths of the grid bars 219a different in the axial direction A, the aforementioned purpose of making each contact point on a different virtual plane can be achieved. In addition, each pair of grid bars 219a can be regarded as having a disconnection gap. Compared with connected grid bars without a disconnection gap, this structure can effectively reduce the stress of the grid bars 219a at the bending position, so it has Less prone to deformation.

In some embodiments, the elastic connector 127 may also have the same or similar structure to the elastic connector 219, which will not be repeated here. As a result, the elastic connector 127 having the structural feature as shown in FIG. 9 can effectively disperse the outer peripheral surface of the first conductive terminal 213 after the electrical connector plug 200 has been plugged and unplugged a considerable number of times with respect to the electrical connector 120 Of the wear area, thereby extending the life of the first conductive terminal 213.

In some embodiments, the first conductive terminal 213 may have a shape other than the circular shape shown. For example, when viewed along the axial direction A, the first conductive terminal 213 may have a square shape or other than a square shape. The polygonal shape (for example, triangle, rectangle, pentagon, hexagon, heptagon, octagon or polygon with more than eight sides).

In the exemplary embodiment shown in FIG. 4 and FIG. 5A, the second conductive terminal 214 is disposed on the inner surface of the ring-shaped electrical terminal housing 212. The second conductive terminal 214 may be formed of a conductive material (for example, a conductive metal). When viewed along the central axis A, the cross section of the second conductive terminal 214 is circular. The second conductive terminal 214 is in electrical contact with the elastic connector 220. The elastic connector 220 is a spring-like member that can be compressed in a transverse direction perpendicular to the axial direction A. The diameter and length of the elastic connector 220 are greater than the elastic connectors 127 and 219. The compression characteristic of the elastic connector 220 allows the electrical connector plug 200 to be inserted into the electrical connector 120 and achieve a low resistance electrical connection between the second conductive terminal 123 and the second conductive terminal 214.

In some embodiments, the elastic connector 220 may also have the same or similar structure as the elastic connector 219, which will not be repeated here. Thereby, the elastic connector 220 having the structural features as shown in Fig. 9 can effectively disperse the outer peripheral surface of the second conductive terminal 123 after the electrical connector plug 200 has been inserted and removed a considerable number of times with respect to the electrical connector 120 Of the wear area, thereby extending the life of the second conductive terminal 123.

The second conductive terminal 214 may have a shape other than the circular shape shown. For example, when viewed along the axial direction A, the second conductive terminal 214 may have a square shape or a polygonal shape other than a square (for example, triangle, rectangle, pentagon, hexagon, heptagon, octagon, or Polygons with more than eight sides).

From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the electrical connector plug of the present invention, the elastic conductive member arranged in the groove of the conductive terminal can be provided when the test terminal is inserted into the groove. One end of the test terminal is in contact and squeezed, and can continuously maintain contact with the test terminal during the squeezing period, so it can be used as a stable transmission path for transmitting electrical signals between the conductive terminal and the test terminal.
