Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In this embodiment, refer to Figure 1 - Figure 3 The power battery interconnection connector specifically implemented therein includes a male plug 1 and a female socket 2 that are plugged into each other. The female socket 2 includes an insulating shell 21 and a conductive tongue 22 disposed inside the insulating shell 21. The two ends of the conductive tongue 22 are respectively provided with a first contact part 2201 and a second contact part 2202. The first contact part 2201 is in contact with the male plug 1, and the second contact part 2202 extends outward and is electrically connected to the power battery.

[0019] Furthermore, the insulating shell 21 is provided with a positioning groove 2101 for interlocking with the male plug 1 on the outer side of the first contact part 2201. In this embodiment, the male plug 1 includes an insulating shell 11 and a conductive plate 12 disposed in the insulating shell 11. One end of the conductive plate 12 is provided with a receiving groove 1201 for interlocking with the second contact part 2202. The insulating shell 11 is also covered with an insertion part 1101 for interlocking with the positioning groove 2101 on the outer side of the conductive plate 12.

[0020] Furthermore, the male plug 1 and the female socket 2 are fixedly connected by a screw 3. The insulating shell 21 is provided with a threaded hole 4 for connecting with the screw 3. The screw 3 passes through the male plug 1 and connects with the threaded hole 4. Specifically, the screw 3 passes through the insulating shell 11 of the male plug 1 and the insulating shell 21 of the female socket 2 and is tightened into the pre-set threaded hole to ensure a stable connection between the male plug 1 and the female socket 2. In specific implementations, to improve the tightness and stability of the screw 3 connection, threaded holes 4 matching the screw 3 can be provided on both the insulating shell 11 and the insulating shell 21. The screw 3 achieves a fixed connection by being screwed into the threaded hole 4.

[0021] Furthermore, two elastic plug-in posts 2102 are symmetrically arranged at the lower end of the insulating shell 21. The elastic plug-in posts 2102 are used to connect with the external power battery, so that the female socket 2 can be stably fixed on the external power battery. The middle part of the elastic plug-in post 2102 is hollow, and several shrinkage grooves 2103 are provided through the elastic plug-in post 2102. The shrinkage grooves 2103 enable the elastic plug-in post 2102 to undergo elastic deformation when subjected to external force, thereby better completing the plug-in and fixed installation.

[0022] Furthermore, the bottom of the elastic plug 2102 tapers inward to form a guide portion 2104. The guide portion 2104 facilitates the smooth insertion of the elastic plug 2102 into the power battery's connector hole, acting as a guide and making the insertion process smoother. Simultaneously, the guide portion 2104 also increases the contact area between the elastic plug 2102 and the power battery connector hole, improving the stability and reliability of the connection.

[0023] Furthermore, in order to improve the waterproof performance of the power battery interconnection connector, a waterproof sealing ring can be provided on the part of the insulating shell 21 of the female socket 2 that contacts the power battery. The waterproof sealing ring can effectively prevent moisture or other liquids from entering the connector, thereby protecting the internal conductive components from damage and ensuring the normal operation of the connector.

[0024] In practical implementation, the structure of the power battery interconnect connector can be adjusted and optimized according to the type, specifications, and usage scenarios of the power battery to meet the needs of different users. For example, for large power battery packs, larger male plugs 1 and female sockets 2 can be used to increase connection stability and current carrying capacity; for applications requiring frequent plugging and unplugging, a more durable and easy-to-operate plugging structure can be used to improve the connector's service life and ease of operation.

[0025] The power battery interconnect connector provided by this utility model has the advantages of simple structure, reliable connection, and easy disassembly. Quick connection is achieved through the interlocking male plug 1 and female socket 2, while the use of screws 3 for fixing further improves connection stability. The positioning groove 2101 design on the insulating shell 21 ensures accurate insertion between the male plug 1 and female socket 2, avoiding connection deviation. Furthermore, the flexible insertion post 2102 not only facilitates the installation and disassembly of the connector but also provides a certain buffering effect during connection, protecting the connector from damage. This power battery interconnect connector meets the high requirements of modern new energy vehicles for power battery connections.
