Ensuring the safety and stability of the power supply is critical to today's society. However, mishandling wire connections can present a number of problems to people. Currently, most of the connections used are those in which the wires are wound directly around the connector. However, this approach often results in a weak connection and poor insulation and waterproofing properties. Wire breakage or short circuit is liable to occur. Moreover, this process is cumbersome and time consuming and has a degree of randomness. Another connection mode is that the insulating tape is used for fixing the wire for butt joint, when the wire is connected with the circuit board of the electric appliance, the opening of the electric appliance shell is generally smaller, so that after the wire of the circuit board of the electric appliance is directly pulled out and connected with the power supply wire, the wire is fixed by using the insulating tape for butt joint, and the connection is not firm enough.

Therefore, a wire connector is currently used, which is fixed to the butt-jointed copper sheets by bolting. However, this construction makes it difficult to achieve wire fixation when butt-jointing some thicker wire copper wires. Moreover, the shell needs to be dismantled to expose the butt joint copper sheet and the screw when connecting, so that the butt joint is very troublesome to fix, and the waterproof performance is lacking, thereby influencing the use effect.
