Abstract

The invention relates to a leakage protection PCB suitable for automatic welding, and a welding process thereof. The leakage protection PCB comprises a PCB main body, the middle part of the PCB main body is provided with a positioning hole used for clamping and fixing the PCB main body, the surface of the PCB is provided with at least two plane bonding pads, the at least two planar bonding pads comprise a first bonding pad and a second bonding pad which are connected with a lead of the mutual inductor, a jig is adopted to position the PCB main body in the connection process, and a plurality of guide grooves are formed in the positions, corresponding to the lead or an input phase line, of the edge of the PCB main body on the surface of the jig. The welding problem during automatic machining of the leakage protector is solved, machining and production are facilitated, and the labor cost can be reduced while the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of leakage protectors, in particular to a leakage protector PCB suitable for automatic welding and a welding process thereof. Background technique [0002] Leakage protector, referred to as leakage switch, also known as leakage circuit breaker, is mainly used to protect the electric shock of the person with fatal danger when the equipment has a leakage fault. Short circuit can also be used as an infrequent switching start of the line under normal conditions. However, the existing earth leakage protectors have complex structures, loose structures, are not easy to assemble, and are difficult to be processed by automatic equipment during production, which does not conform to the development trend of current automatic production. [0003] Therefore, how to adjust the internal structure of the earth leakage protector to facilitate automatic welding is a technical problem urgently to be solved at present. Conte...
