The common wire connection is generally that the wire cores are wound together, and then the periphery is wrapped with insulating tape to avoid electric leakage. However, the connection mode is relatively poor in use safety along with the time, and particularly, the connection mode is applied to an electric vehicle or a motorcycle, the insulating tape is easy to break and loosen due to bumping of the vehicle, and the connection end of the wire core is easy to loosen, so that the electric leakage or the disconnection phenomenon occurs.
Connectors for connecting the ends of wires are also known on some power lines, in which a cylindrical socket and a cylindrical plug are provided, which are connected to the wire core to be connected, and the connection of the wires is achieved by plugging the plug into the socket. However, in this connector, since the conductive connection of two wires is achieved by only the plug-in fitting of the plug and the socket, the bending deflection of the jack itself cannot be large, otherwise the plug and the jack are not easy to realize plug-in fit. In the use process of the connector, as the stability of the connector in the use process is relatively poor, the degree of matching between the socket and the plug is small, and sometimes even the plug and the socket are loosened. If the matching degree of the plug and the socket is poor, when the high-current power supply is realized, spark is easy to generate between the plug and the socket to ablate the socket. And after the plug and the socket are loosened, the disconnection condition can occur. Therefore, the use stability of such connectors is poor.
