When we use the wooden cable drum, we often have problems with power -offs or poor contact. There are some contact problems of dead plugs and sockets. Drum cable problem.
The cable failure is mainly divided into five types. Today we will analyze it in detail:
1. Leakage
Causes: moisture or water; the wires of the plug are exposed; damage; protect the ground wiring error.
2. The circuit is not connected
Caused by: The socket socket is too loose, the plug is not touched; the screws of the socket wire connection fall; the power supply lead is broken;
3. Poor contact
Caused by: plug pressing screw loosening or welding welding; disconnecting the internal power cord of the plug root; the screw loose or wire corrosion of the socket connection; too loose plug socket; poor mass quality.
4. Short -circuit
Caused by: The wire head is exposed in the socket or plug that it is too long or there is a burr;
5. Broken
Cause: Damage the rubber cover by the impact of external forces; copper or connection column due to short -circuit burning sockets;
