AI Technical Summary

Technical Problem

Existing junction boxes lack electromagnetic interference resistance and dustproof structures, which makes them susceptible to external magnetic field interference and prone to dust accumulation after prolonged use.

Method used

A junction box for wire harness connection was designed, comprising components such as a box body, dust baffle, fixing base, circuit board, limiting post, limiting frame, outer sealing plate and antistatic sponge. The limiting frame and outer sealing plate work together to achieve anti-interference protection, and the bottom air hole and top air groove ensure internal temperature balance and dust prevention.

Benefits of technology

It improves the junction box's anti-interference capability and dustproof performance, ensures the stability and safety of wire connections, prevents dust from entering, and maintains internal temperature balance.

Abstract

The utility model relates to the technical field of junction box, and disclose the junction box for wiring harness connection including box body, the top fixedly connected with the baffle of keeping out dust of box body, the inner chamber fixedly connected with the fixed base of box body, the one side of fixed base is installed with the circuit board, the both sides fixedly connected with the limit post of box body outside, the front fixedly connected with the limit frame of box body. This junction box for wiring harness connection, through the limit frame fixedly connected in the front of box body, when this device is in wiring and is fixed on the wall after completing, will slide and connect the inside of limit frame with the outer sealing plate, then will be inserted into the round groove of outer sealing plate surface and is screwed in the threaded hole that opens in the front of box body, thus make the surface of box body be blocked, and through the anti -staticity sponge of outer sealing plate inside joint, thus reached to the one side of this device facing the outside world effectively anti -interference protection, improved the practicality of this device.
