By rotating the guide core 5, the two protrusions 6 can simultaneously abut and fix the cores of the two wires 7 to be connected. Therefore, the wiring work can be completed quickly without the assistance of tools.

[0043] like Figure 5 As shown, the surface of the protrusion 6 is an arc surface. In order to prevent the protrusion 6 from damaging the wire core 7, its surface is designed to be an arc surface, which will not damage the surface of the wire core when it contacts the wire core.

[0044] like Figures 3 and 4 As shown, a positioning rubber sleeve 8 is bonded and fixed in the wire entry 4, and the core of the wire 7 is inserted into the positioning rubber sleeve 8.

[0050] The working principle of this utility model:

[0051] Before use, the lower half wiring housing 2 is first fixed to the power box of the lap welding machine by installing countersunk bolts in the countersunk holes 20. After the guide core 5 is placed in the lower half wiring housing 2, the half wiring housing and the lower half wiring housing 2 are fixed by installing screws in the second screw hole 21. Finally, the self-locking housing 11 is fixed to the upper half wiring housing 1 by installing screws in the first screw hole 19.

[0052] When in use, it is only necessary to insert the core of the wire 7 into the positioning rubber sleeve 8 in the wire inlet 4. Figure 3 As shown, by rotating the rotating head 10 in one direction, the guide core 5 can make the two protrusions 6 simultaneously abut and fix the cores of the two wires 7 to be connected, as shown in FIG. Figure 4 As shown, since the guide core 5 can self-lock after rotation, that is, the striker 13 is always in contact between two adjacent ratchet teeth under the elastic push of the spring 16, the ratchet 12 cannot rotate in the opposite direction at this time, so it does not need the assistance of tools when wiring, and the wiring work can be completed quickly. At this time, the two wires 7 can be energized through the guide core 5.

[0053] When the electric wire 7 is to be removed, the striker 13 is pulled outwards so that the striker 13 is disengaged from between the ratchet teeth, and the ratchet 12 is then rotated in the reverse direction, thereby achieving the removal of the electric wire 7 .

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
