At the same time, the contact knife 2021 can also be used to contact the wire to stabilize and effectively limit the wire, so as to achieve a stable and effective connection of the wire and prevent the wire from sliding off. The ear plate slides against the contact plate 2031 provided at the lower part of the pressing block 203, so that the ear plate can be effectively pushed against when the pressing block 203 is inserted into the base 201. The push block 203 is moved, thereby driving the skin-breaking contact knife 2021 to contact the wire, and at the same time, the insulation skin of the wire is cut in the process. The second clamping strips 2033 on both sides of the push block 203 are clamped on the first clamping strips 2012 set on both sides of the base 201, and the push block 203 is stably fixed on the base 201 to ensure that the wiring assembly 2 stably connects the wire to the protector body 1. A wire threading hole 2034 is provided in the middle position of the push block 203 to facilitate the insertion of the wire end into the conductive seat 202, thereby improving the convenience of wire connection.
