[0002] With the rapid development of electric vehicle technology, the requirements for battery connectors are becoming increasingly higher, especially for the rapid plugging and unplugging of batteries, the stability of electrode contact, and the accuracy of signal transmission. The battery connectors in the existing technology mainly use ordinary plugs, most of which only have positive and negative poles, and lack battery management systems (BMS), remote monitoring and diagnosis, etc., which makes it difficult to adapt to the development of battery-swap electric vehicles. In order to be safer and more intelligent, it is necessary to add a battery management system, remote monitoring and diagnosis, etc. inside the battery and connect it to the vehicle. However, the current electric vehicle connectors basically have no signal terminals and are easily affected by the environment, resulting in unstable signal transmission and poor anti-interference ability.

[0005] Furthermore, fixing holes are provided on the base and the seat, and a groove is provided on the base to surround the negative electrode sleeve, positioning guide tube, and sheath. A groove is provided on the seat to surround the negative electrode tube, positioning guide column, and signal pin. The groove is used to place a sealing ring so that the plug or socket can be sealed and installed on other components.

[0006] More preferably, the positive electrode pin and negative electrode tube are mounted within an injection molded part, which is secured to the base. The positioning guide pin is connected to a ground wire on the PCB, providing both positioning and grounding functions. The signal pin and positioning guide pin are electrically connected to a communication plug on the PCB via the PCB.

[0007] Optionally, the signal pins are divided into two groups, each group has 6 pins, and are symmetrically arranged on the left and right sides of the negative tube, and are all wrapped by a sheath to achieve blind insertion of the socket and plug in both directions.

[0013] Compared to existing technologies, this new design positions the positive and negative power lines in the center of the socket or plug, shielding the current and magnetic field by wrapping the negative pole around the positive pole.
