Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a plug electrical connector, a socket electrical connector and an electrical connector combination. Background Art

[0002] New energy vehicles are a new trend in the development of automobiles. So-called new energy vehicles use electric energy to drive vehicles, using batteries to provide electricity to drive motors, and using the torque output by motors as the power source to drive the vehicle. When the battery power is consumed to a certain extent, users use cables to connect the battery to a charger to charge the battery.

[0003] In order to improve the user experience, one of the current development trends of new energy vehicles is to shorten the charging time. In this way, the charging power needs to be increased, and therefore the current value during charging needs to be increased. The existing electrical connectors for connecting charging cables use parallel copper wires to achieve current transmission. However, with the trend of increasing charging current values, it is necessary to increase the diameter of the copper wire of the charging cable. On the one hand, this will increase the width of the charging cable, and on the other hand, the increase in the volume of the copper wire will also increase the weight of the copper wire. Although this shortens the charging time, users must use cables that are wide and relatively heavy, which will also have a negative impact on the user experience.

[0004] For the above problems, the solution currently proposed is to replace the traditional copper wire with an aluminum flat conductor. The specific gravity of aluminum material is lower than that of copper material. Under the same weight limit, the wire width can be increased to transmit a larger current. In addition, in order not to increase the overall width of the cable and the electrical connector too much, in the plug electrical connector, the aluminum conductors are arranged in a staggered manner, such as the content disclosed in Chinese patent CN116435819A, or the aluminum conductors are arranged in an overlapping manner, such as the content disclosed in Chinese patent CN116404463A. However, according to the content disclosed in Chinese patent CN116435819A or Chinese patent CN116404463A, although a plug back cover is provided behind the two aluminum conductors, there is no other supporting structure between the two aluminum conductors except for the sealing ring. The sealing ring has a good sealing effect and is usually made of flexible material. Therefore, the sealing ring cannot support the two aluminum conductors.

[0005] In addition, the columnar terminals of the socket electrical connectors of Chinese Patent CN116435819A and Chinese Patent CN116404463A are usually exposed to the outside, and the user may accidentally touch the columnar terminals with his fingers or tools during use, causing electric shock. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of the present application is to provide a plug electrical connector, a socket electrical connector and an electrical connector combination, which are used to solve the problem of the lack of support between the conductors of the plug electrical connector in the prior art, and also solve the problem of the columnar conductors of the socket electrical connector being exposed to the outside and easily causing electric shock to the user.

[0007] To achieve the above-mentioned purpose and other related purposes, the present application provides a plug electrical connector, which includes a first conductor, a second conductor and a conductor support. The first conductor has a first connecting portion and a first extension portion connected to the first connecting portion, and the first extension portion extends along a first direction. The second conductor has a second connecting portion and a second extension portion connected to the second connecting portion, and the second extension portion extends along a first direction. The second extension portion and the first extension portion are offset in the second direction, and the projections of the second extension portion and the first extension portion in the third direction are at least partially overlapped, and the first direction, the second direction and the third direction are orthogonal to each other. The conductor support includes a surrounding portion and a positioning portion, the surrounding portion surrounds the first extension portion and the second extension portion, the surrounding portion has a first side edge and a second side edge that are arranged oppositely, the positioning portion is connected to the first side edge at a first position, the positioning portion is connected to the two side edges at a second position, and the positioning portion is located between the first extension portion and the second extension portion. The first position and the second position are offset, so that the positioning portion forms a bending shape.

[0008] The present application provides a socket electrical connector, which includes an insulating base, two conductor posts and two protective sleeves. Each conductor post has a fixed end and a butt end, the fixed end is arranged on the insulating base, and the butt end is used to butt with a plug electrical connector. The two protective sleeves are respectively movably arranged on the partial structures of the two conductor posts close to the butt ends, and move between a shielding position for shielding the butt ends and an exposed position for exposing the butt ends.

[0009] The present application provides an electrical connector combination, which includes a plug electrical connector and a socket electrical connector. The plug electrical connector includes a first conductor, a second conductor, two electrical connection sleeves, an insulating structure and an outer cover, the two electrical connection sleeves are respectively combined with the first conductor and the second conductor, one end of the insulating structure is combined with the two electrical connection sleeves, the outer cover and the insulating structure are arranged on opposite sides of the first conductor and the second conductor, the outer cover has two through holes, and the two electrical connection sleeves extend into the two through holes respectively. When the plug electrical connector and the socket electrical connector are docked, the two conductor posts are respectively inserted into the two through holes of the outer cover, the two electrical connection sleeves respectively push the two protective kits to move the two protective kits and the docking ends of the two conductor posts are respectively inserted into the electrical connection sleeves to form an electrical connection.

[0010] As described above, the plug electrical connector of the present application has the following beneficial effects: by arranging a conductor support between the first conductor and the second conductor, the conductor support includes a surrounding portion and a positioning portion, the surrounding portion surrounds the first extension portion of the first conductor and the second extension portion of the second conductor to support the first conductor and the second conductor, and the positioning portion of the conductor support is arranged between the first extension portion and the second extension portion to maintain the relative positions of the first conductor and the second conductor to each other, thereby supporting the first conductor and the second conductor from the outside while also maintaining the positioning between the first conductor and the second conductor.

[0011] The socket electrical connector of the present application has the following beneficial effects: by providing a protection kit outside the butt end of the conductor post, the conductor post can be prevented from being exposed to the outside, and the user will not have the problem of electric shock during operation.

[0012] The electrical connector combination of the present application has the following beneficial effects: when the plug electrical connector is docked with the socket electrical connector, the electrical connection sleeve of the plug electrical connector pushes the protective kit of the socket electrical connector, so that the protective kit moves to an exposed position, and the docking end of the conductor column is exposed and contacts the electrical connection sleeve to form an electrical connection. When the plug electrical connector is separated from the socket electrical connector, the outer cover of the plug electrical connector drives the protective kit to reset, so that the protective kit covers the docking end of the conductor column again. In this way, when the socket electrical connector is not in use, the protective kit covers the conductor column to prevent the user from accidentally causing electric shock during operation. When the socket electrical connector is docked with the plug electrical connector, the protective kit moves to make the conductor column contact the electrical connection sleeve to form an electrical connection.

Each electrical connection sleeve 17 has a sleeve portion 171 and a flange portion 172 arranged on the outer circumference of the sleeve portion 171. The flange portion 172 is annular. The sleeve portions 171 of the two electrical connection sleeves 17 are respectively inserted into the first through hole 111a and the second through hole 121a, so that the flange portions 172 of the two electrical connection sleeves 17 are respectively abutted against the first connection portion 111 and the second connection portion 112. A spring sheet 173 is arranged in the sleeve portion 171, which is used to abut against the conductor column of the socket electrical connector 20 to form an electrical connection.

[0036] See also Figure 3 Also see Fig.12 and Fig.13 ,in Fig.13This is a stereoscopic view of the plug electrical connector of an embodiment of the present application from another perspective.

The other end of the insulating structure 18 has two snap-fitting protrusions 182, and the snap-fitting protrusions 182 abut against the outer circumference of the flange portion 172 of the electrical connection sleeve 17, so that the insulating structure 18 forms a limit in the first direction L1. In this way, the insulating structure 18 forms a limit in the first direction L1, the second direction L2 and the third direction L3 by combining with the conductor support 13 and the electrical connection sleeve 17.

When the plug electrical connector 10 is mated with the socket electrical connector 20, the front opening 10a1 of the shell 10a is aligned with the socket electrical connector 20 for mating. Since the bracket seal 16 is located between the conductor support 13 and the shell 10a, the bracket seal 16 can play a waterproof sealing effect between the conductor support 13 and the shell 10a.

[0039] See also Figure 2 , Figure 4 and Fig.14 ,in Fig.14 Display as Figure 2 The cross-sectional view of the socket electrical connector along the CC line shows that the socket electrical connector 20 of the present embodiment comprises an insulating base 21, two conductor posts 22, two protection sleeves 23 and two protection end pieces 24.

The two sleeve parts 212 are arranged on the base body 211, and the two outer sleeve parts 213 are arranged on the base body 211 and respectively surround the two sleeve parts 212. There is a gap between the inner circumferential wall of each outer sleeve part 213 and the outer circumferential wall of the corresponding sleeve part 212. The two conductor posts 22 are positioned in the two sleeve parts 212. The partial structure of each conductor post 22 close to the butt end 222 protrudes from the opening of the corresponding sleeve part 212. The two protection covers 23 are respectively movably arranged in the gap between the sleeve part 212 and the outer sleeve part 213, and move between a shielding position for shielding the butt end 222 of the conductor post 22 and an exposed position for exposing the butt end 222 of the conductor post 22. The protection end piece 24 covers the butt end 222 of the conductor post 22 . When the protection sleeve 23 is located at the shielding position, the protection sleeve 23 and the protection end piece 24 completely shield the butt end 222 of the conductor post 22 .

[0041] The outer peripheral wall of each sleeve portion 212 has an expanded diameter portion 2121 , and the inner peripheral wall of the protection kit 23 abuts against the expanded diameter portion 2121 .

[0045] The socket electrical connector of the present application can prevent the conductor post from being exposed to the outside by providing a protection kit on the outside of the butt end of the conductor post, so that the user will not have the problem of electric shock during operation.

[0046] In the electrical connector combination of the present application, when the plug electrical connector is docked with the socket electrical connector, the electrical connection sleeve of the plug electrical connector pushes the protective kit of the socket electrical connector, so that the protective kit moves to an exposed position, and the docking end of the conductor column is exposed and contacts the electrical connection sleeve to form an electrical connection. When the plug electrical connector is separated from the socket electrical connector, the protective kit is reset by the outer cover of the plug electrical connector, so that the protective kit covers the docking end of the conductor column again. In this way, when the socket electrical connector is not in use, the protective kit covers the conductor column to prevent the user from accidentally causing electric shock during operation. When the socket electrical connector is docked with the plug electrical connector, the protective kit moves to make the conductor column contact the electrical connection sleeve to form an electrical connection.
