The wire pipe is connected to the junction box, and the wires inside the pipe are connected in the junction box, which plays a role in protecting and connecting the wires. In an electric vehicle, a junction box is often used for wiring, and the junction box for electric vehicles is mainly used for the connection between the controller and the power supply.

If not cleaned for a long time, it may cause electric leakage and sparking, leading to a fire, affecting the performance, heat dissipation and service life of electrical appliances, etc., causing potential safety hazards. After improving the sealing performance, the common fixing method is bolt fixing, which is not portable and convenient, and it is impossible to achieve the effect of quick disassembly and assembly without tools. Therefore, an electric vehicle junction box is introduced to solve such problems. Content of the Utility Model

[0013] Technical effects and advantages of the present utility model:

[0014] 1. By providing the first locking plate, the second locking plate, the sliding groove, the limiting strip, the sliding ring, the connecting strip, and the knob, the present utility model can directly rotate the knob during later use, and the sliding ring is driven to rotate by the knob. When the knob is in the horizontal state, the first locking plate and the second locking plate are not locked. When the knob is rotated to the vertical state, the first locking plate and the second locking plate are locked. By providing positive and negative magnets at both ends of the limiting strip and the sliding ring, it can be ensured that the knob and the sliding ring will not rotate automatically when not rotated manually, ensuring the sealing performance after the upper housing and the lower housing are locked, preventing dust from accumulating inside and causing potential safety hazards, and making disassembly and assembly more convenient, improving the safety and portability of the junction box during use.
