[0055] refer to Figure 6A clamping block 216 is provided on one of the plug housing 210 and the elastic sleeve 230, and a clamping slot 231 is provided on the other of the plug housing 210 and the elastic sleeve 230. The clamping block 216 is clamped in the clamping slot 231. That is, the elastic sleeve 230 is clamped on the plug housing 210, which facilitates the installation of the elastic sleeve 230 and the plug housing 210.

[0056] In a possible embodiment, a buckle including a slot 231 is provided on the elastic wire sleeve 230, and a block 216 is provided on the outer wall of the plug housing 210. When the elastic wire sleeve 230 and the plug housing 210 are assembled, a portion of the elastic wire sleeve 230 located on one side of the buckle is accommodated in the plug housing 210, and a portion of the elastic wire sleeve 230 located on the other side of the buckle is outside the plug housing 210, so as to abut against one end of the plug housing 210 for limiting the position, so as to fix the elastic wire sleeve 230 on the plug housing 210.

[0057] When the second sub-conductive member 420 is connected to the first sub-conductive member 410, one end of the second sub-conductive member 420 is inserted into the elastic sleeve 230, and the part of the elastic sleeve 230 contained in the plug housing 210 squeezes the second sub-conductive member 420 to prevent foreign matter, gas and liquid from entering the inside of the plug housing 210 from the elastic sleeve 230, thereby forming a seal between the elastic sleeve 230 and the second sub-conductive member 420. Specifically, the elastic sleeve 230 and the sealing member 600 are made of elastic materials such as plastic and rubber, and the elastic sleeve 230 and the sealing member 600 are respectively arranged at both ends of the plug housing 210 to seal the two ends of the plug housing 210, so that the connector as a whole can meet the IP68 waterproof requirement when used.

[0058] The plug housing 210 is a metal part, and the material of the plug housing 210 can be copper, aluminum, etc. The metal plug housing 210 can absorb and reflect electromagnetic waves to form an electromagnetic shield. The material of the plug insulator 220 can be PE (polyethylene), PP (polypropylene), ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), PET (polyethylene terephthalate), etc.

[0059] refer to Figure 7 , Figure 8 and Fig. 9The socket 300 includes a first part 310 and a second part 320 connected to each other. The outer diameter of the first part 310 is larger than the outer diameter of the second part 320, and the first part 310 is received in the first receiving groove 213 of the plug 200. The second part 320 is used to receive the second conductive member 500. Specifically, the first part 310 is located outside the battery case 100, and the second part 320 is embedded in the through hole 110 of the battery case 100, and is supported on the outer wall of the case through the first part 310. A mounting hole 311 is provided on the first part 310, and the first part 310 includes a first side wall 312 and a second side wall 313 arranged opposite to each other. The second side wall 313 is arranged on a side of the first part 310 close to the second part 320, and the mounting hole 311 passes through the first side wall 312 and the second side wall 313. The mounting hole 311 is used to install bolts, screws, etc. to fix the socket 300 as a whole on the battery case 100. When the socket 300 is installed, the socket 300 is inserted into the through hole 110 from outside the battery case 100, which facilitates the installation of the socket 300. And only the first part 310 of the socket 300 is exposed outside the battery case 100, and the size of the socket 300 exposed outside the battery case 100 is small, which can save space outside the battery case 100 and increase the space reserved for other devices. After the plug 200 is connected to the socket 300, the plug housing 210 is fixed to the outer wall of the battery case 100 by fasteners such as bolts and screws. At this time, the first part 310 of the socket 300 is accommodated in the socket 300 housing, so that the socket 300 can be protected and sealed, and the plug housing 210 provides the main support for the connector as a whole, simplifying the connector structure.

[0060] Since the plug housing 210 is a metal part, the first part 310 of the socket 300 is accommodated in the plug housing 210. The plug housing 210 can reduce the impact of electromagnetic interference on the first conductive part 400 and the second conductive part 500, reduce the number of parts, and protect the first conductive part 400 and the second conductive part 500 from damage by electromagnetic interference and radiation, thereby extending the service life.

[0061] In the present application, the first part 310 of the socket 300 exposed outside the battery case 100 is accommodated in the plug housing 210, so that the sealing between the plug 200 and the battery case 100, and the sealing between the socket 300 and the battery case 100 can be achieved through a seal 600, thereby reducing the number of parts of the connector, making the connector assembly easier, and reducing the weight of the connector.

[0062] The first part 310 of the socket 300 is recessed on one end surface away from the second part 320 to form a third receiving groove 314, that is, the first side wall 312 is recessed to form the third receiving groove 314, and the second conductive member 500 is installed in the third receiving groove 314. Specifically, the second conductive member 500 extends along the length direction of the socket 300, and one end of the second conductive member 500 extends into the battery box 100 and is connected to the battery cell through the copper busbar. The second conductive member 500 is entirely accommodated in the third receiving groove 314, so that the second conductive member 500 is insulated and protected to prevent people from accidentally touching the second conductive member 500.

[0063] Optionally, the second conductive member 500 is snap-fitted into the third receiving groove 314 for easy assembly and disassembly, so that different second conductive members 500 can be replaced according to the size of the copper bar connecting the battery cell, which not only ensures the reliability of the electrical connection between the copper bar and the second conductive member 500, but also improves the compatibility of the socket 300. A slot 510 is provided on the second conductive member 500, one end of the first sub-conductive member 410 is inserted into the slot 510, and the other end of the first sub-conductive member 410 is connected to the second sub-conductive member 420.

[0064] refer to Fig.10 , the second part 320 of the socket 300 is provided with a support portion 321, a first limiting portion 322 and a second limiting portion 323, the support portion 321 is connected between the first limiting portion 322 and the second limiting portion 323 to support the first limiting portion 322 and the second limiting portion 323, the first limiting portion 322 is used to install the insulating member, and the second limiting portion 323 is used to limit the rotation of the socket 300. In practical application, the second conductive member 500 includes a plurality of copper bars of the battery core connected to the second conductive member 500, and an insulating baffle is inserted into the first limiting portion 322 to increase the electrical gap between the copper bars. When the second conductive member 500 is bolted to the copper bar of the battery core, the support portion 321 provides positive force support for the bolt, and at the same time, it can be confirmed whether the bolt is installed in place. The second limiting portion 323 provides torsional support for the bolt, which can limit the rotation of the socket 300 due to excessive torque when the second conductive member 500 and the copper bar of the battery core are installed.

[0065] refer to Fig.11 , Fig.12 and Fig.13 In the connector provided by the present application, the number of the first conductive member 400 and the second conductive member 500 is multiple, and the number of the first conductive member 400 and the second conductive member 500 corresponds to each other. The first conductive member 400 can be a plug pin, and the first sub-conductive member 410 and the second sub-conductive member 420 have an outlet mode of 90°, 120°, 180°, etc., so the overall shape of the plug 200 is also roughly 90° (reference Fig.11 ), 120°(reference Fig.12 ), 180°(reference Fig.13 ) and other angles. By bending the first sub-conductive member 410, connection with the wiring harness at different angles can be achieved, and the first conductive member 400 and the second conductive member 500 are connected in a plug-in manner, and the second conductive member 500 can be adapted to be connected with different first conductive members 400, thereby improving the versatility of the socket 300.

[0066] The connector provided in the present application has an electromagnetic shielding function and high sealing performance, and is therefore suitable for the transmission of high voltage and high current, including but not limited to the connection between the battery of the vehicle and the drive motor, generator, charging port socket 300, etc. In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
