[0002] The chargers on the market generally consist of two parts: a power cord and a plug. The power cord is the wire that transmits current. Usually the current is transmitted point-to-point, and the plug is the connector that connects the power cord to the socket and plays an important role.

[0003] There are two types of charger plugs on the market, namely three-core plugs and two-core plugs. The two-core plug charger is suitable for low-power electrical appliances, and the three-core plug charger is suitable for high-power electrical appliances. Some two-core plug chargers, such as mobile phone chargers, can be disconnected from the plug, and the plug or the power cord can be replaced separately. However, during the production of the three-core plug charger, due to the limitations of production requirements, the power cord and the plug are usually fixedly connected together, resulting in the need to replace the power cord separately when the power cord is damaged. The power cord of the existing three-core plug is generally fixedly connected, and the operation is cumbersome when replacing the power cord, and tools are required. In addition, a loose connection is prone to short circuit.
