1, the socket squeaks, indicating poor internal contact of the socket.

2. Handling method of poor contact of socket:

General sockets may have poor contact due to their own quality problems or the influence of service life, and can be removed and eliminated according to specific failure reasons.

(1). The contact copper sheet is deformed due to frequent use or long service life. If the copper sheet has not lost its elasticity, tools such as pliers can be used to shape the copper sheet into a suitable state.

(2) Because the fixing screws are often loose, it is only necessary to re-imprison the fixing screws.

(3) If the contact copper sheet of the socket has lost its elasticity, it is not recommended to maintain it, and a new socket should be replaced to prevent short circuit.
