[0002] A power plug is a connector that connects a power source to an electrical appliance. When working, the current at the power source is transmitted to the electrical appliance through the plug of the power socket. With the widespread use of high-power equipment such as energy storage in the market, power sockets are widely used. During the use of electricity, the connection part may explode or become hot due to short circuit or overload. Especially when an explosion occurs, although the power end will trigger the corresponding circuit breaker protection, the power socket will usually be damaged by the energy of the explosion. The most common damage is the plug structure. When the power supply end cannot be powered off normally, the damaged plug can easily cause a secondary accident. In addition, the existing flameproof power plug is cumbersome to disassemble and assemble, and is inconvenient to use.
