The first copper bar 2 has a first end and a second end opposite to each other, and the second copper bar 4 has a third end and a fourth end opposite to each other. The second end of the first copper bar 2 extends to the outside of the first installation channel, and the fourth end of the second copper bar 4 extends to the outside of the second installation channel;

[0036] The second end of the first copper bar 2 has a first connecting member 14, and the first connecting member 14 is used to connect the copper bar of the distribution box; the fourth end of the second copper bar 4 has a second connecting member 16, and the second connecting member 16 is used to connect the copper bar of the battery pack;

[0037] The first end of the first copper bar 2 has a connection groove 21. When the plug housing 1 is inserted into the socket housing 3, the first installation channel communicates with the second installation channel. The third end of the second copper bar 4 is inserted into the connection groove and electrically connected to the first end of the first copper bar 2. In this embodiment, the first copper bar 2 and the second copper bar 4 are used for the transmission of large current (high voltage). Compared with the traditional connection through thick copper wires, by electrically connecting the first copper bar 2 to the distribution box and the second copper bar 4 to the battery pack, the use of copper materials can be reduced to a certain extent, thereby reducing the cost of electrical connection. In addition, both the plug housing 1 and the socket housing 3 are composed of a detachable rubber core and a bottom shell.

When the plug housing 1 is connected to the socket housing 3, the first protrusion 5 is inserted into the fourth installation channel 61, so that the second copper bar 4 located in the fourth installation channel 61 extends into the third installation channel 51 and is electrically connected to the first copper bar 2 located in the third installation channel 51. The settings of the first protrusion 5 and the second protrusion 6 can play a limiting role, so that when the plug housing 1 is connected to the socket housing 3, the first copper bar 2 and the second copper bar 4 can be accurately connected together.

[0041] In one embodiment, the socket housing 3 has an opening groove 7 surrounding the first protrusion 5.

In this embodiment, the structure of the signal terminal 9 is the same as that of the power terminal 8. The signal terminal 9 is mainly used for transmitting signals, and the current transmitted between the signal terminals 9 is less than the current transmitted between the power terminals 8. In this embodiment, the power terminal 8 is used for transmitting small current, that is, the current transmitted in the power terminal 8 is less than the current transmitted between the first copper bar 2 and the second copper bar 4. At the same time, circular channels are provided at both ends of the power jack terminal 81. One end of the circular channel is used for electrically connecting with a cable, and the circular channel at the other end is used for accommodating a part of the power pin terminal 82 and electrically connecting with the power pin terminal 82; a circular channel is provided at one end of the power pin terminal 82 facing away from the power jack terminal 81 for electrically connecting with a cable. At the same time, channels for installing the power terminal 8 and the signal terminal 9 are provided on the plug assembly 100 and the socket assembly 200, and the power terminal 8 and the signal terminal 9 are installed in the corresponding channels. The electrical connector of this embodiment integrates the transmission of large current, small current and signals, which can save the number of electrical connectors, thereby reducing the space occupied by the electrical connectors, reducing costs, facilitating installation, facilitating vehicle body layout and improving assembly efficiency. In this embodiment, there is also a claw ring for limiting the power terminal 8 and the signal terminal 9.

[0045] In one embodiment, the first end of the first copper bar 2 has a first connection section and a second connection section, and the second connection section is disposed on the first connection section and the two enclose a connection groove 21.

One end of the first connection section facing away from the second copper bar 4 extends out of the plug housing 1. The connection groove 21 is preferably a square groove with three sides open, which can facilitate the connection between the first copper bar 2 and the second copper bar 4. At the same time, elastic locking members are provided on two opposite side walls inside the square groove. When the second copper bar 4 is inserted into the square groove, the second copper bar 4 is inserted between two opposite elastic locking members to further lock the second copper bar 4, so that the first copper bar 2 and the second copper bar 4 are stably electrically connected together.

[0046] In one embodiment, the electrical connector further includes a bushing 10 facilitating the installation of the plug housing 1. The plug housing 1 is provided with a mounting hole, and the bushing 10 is disposed in the mounting hole. The bushing 10 is provided with an inner hole for connection, and the outer peripheral surface of the bushing 10 is arranged with threads. The threads are elastic, and the outer ends of the threads abut against the hole wall of the mounting hole.

In addition, this embodiment further has a nut seat. The nut seat is installed in the mounting hole, and the bushing 10 is sleeved on the nut seat. The connection between the distribution box and the electrical connector is realized by installing the fixing screw in the inner hole of the nut sleeve. In this embodiment, during connection, the elastic bushing 10 can be deformed to eliminate dimensional deviation. Compared with the floating mechanism with a spring installed, the installation of the bushing 10 in this embodiment is of low difficulty and low cost.

The first copper bar 2 and the second copper bar 4 are connected to an external copper bar by screws. In addition, directly providing connection holes on the first copper bar 2 and the second copper bar 4 to connect with an external copper bar is also within the protection scope of this embodiment. During large-current transmission, the first copper bar 2 and the second copper bar 4 are electrically connected to the copper bars of the distribution box and the battery pack (copper bars are provided on the battery pack and the distribution box to replace the cables). The contact resistance is small, the resistance is stable after aging, the current-carrying capacity is strong, and the temperature rise is low, solving the problems of unstable crimp connection, increased resistance after aging, and high temperature rise.

[0048] For the electrical connector according to this embodiment, the first copper bar 2 is connected to the copper bar provided on the distribution box through the first connecting member 14, and the second copper bar 4 is connected to the copper bar provided on the battery pack through the second connecting member 16, so that the circuit between the battery pack and the distribution box is conducted.
