Description

Technical Field

[0001] The invention belongs to the technical field of cable connection, and in particular relates to a connector with a shielding interference layer. Background Art

[0002] In production and life, it is often necessary to connect two cables together. The common practice is to peel off the outer skin of one end of the two wires, twist the wires together, and then use a heat shrink tube or insulating tape to cover the wire connection. Although this connection method is simple to operate and convenient to use, the connection of the wires is easily corroded by water and air, and the connection strength is not high. If the cable connection is not firm and the insulation is poor, leakage is likely to occur during use, which will also have a certain impact on people's personal and property safety. Therefore, there is an urgent need for a connector with a shielding infection layer that can solve the existing problems. Summary of the invention
