Furthermore, the four corners of the lower surface of the upper wire clamp cover plate are fixedly connected with positioning blocks, the upper surface of the lower wire clamp cover plate is fixedly connected with positioning grooves corresponding to the positioning blocks, and the upper wire clamp cover plate is placed on the lower wire clamp cover plate to be more stable through the matching of the positioning blocks and the positioning grooves.

Advantageous effects

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the parallel groove clamp of the utility model fixes the connected wires in the upper clamp cover plate and the lower clamp cover plate through the fastening pressure of the screw and the nut, simultaneously, the flat gasket and the spring washer are transmitted to provide a more uniform and constant pressure effect for the connected wires, simultaneously, the high-strength aluminum alloy is adopted to manufacture and improve the service life without hysteresis loss,

2. the parallel groove clamp of the utility model has the advantages that through the adoption of the arc-shaped grooves, sufficient clearance is reserved between the two grooves, so that the wires are not easy to contact with each other in the clamping process, the phenomenon of power-off discharge is avoided, the safety and the service life of the wires are greatly improved, the smooth bumps in the grooves can effectively protect the outer surfaces of the wires, and stable holding power is provided, and the parallel groove clamp and the wires are prevented from loosening or sliding relatively;

3. the utility model discloses a parallel groove clamp structural design is simple, does benefit to mass production, and the external dimension is small and exquisite, and the security obtains the guarantee also to reduce the cost, and simple to operate improves the installation effectiveness during the simultaneous operation.
