Screw hole reinforcing structure of switch socket

Abstract

A switch socket screw hole reinforcing structure disclosed by the present invention comprises a support, a rear seat and a face shell, the support is provided with a sleeving hole and a mounting hole, the rear seat is fixed on the support, the mounting hole comprises a counter bore and a screw hole which are distributed up and down, the aperture of the counter bore is greater than the aperture of the screw hole, and the mounting hole is located at the side of the sleeving hole; the face shell comprises a cover plate and a reinforcing piece which are integrally formed, the reinforcing piece is arranged on the side, close to the mounting hole, of the cover plate, and a through hole is formed in the reinforcing piece. When the face shell is assembled on the support, the reinforcing pieces are installed in the counter bores at the same time, ultrasonic welding and other procedures do not need to be independently carried out for fixing, the installation efficiency is high, equipment does not need to be additionally arranged, the support can be made of materials with relatively low strength and price, and the material cost is effectively reduced.

Description

technical field [0001] The invention relates to the electrical field, in particular to a screw hole reinforcement structure of a switch socket. Background technique [0002] The basic installation method of the electrician switch socket is to insert the screw into the screw hole on the bracket, fix the bracket to the bottom box on the wall, and then cover the panel. The pressure generated by screw tightening requires the screw hole to have sufficient strength. Most of the electrical switches and sockets on the market are made of engineering plastics such as PC. If they are made of general-purpose plastics with relatively poor mechanical strength and low price, such as PP, the cost can be reduced. However, the screw holes are easily penetrated, which makes the fixed connection invalid. To this end, adding a reinforcement with high mechanical strength to the screw hole can effectively solve the problem of penetration. At present, the reinforcements are generally fixed on th...

AI Technical Summary

Problems solved by technology

At present, reinforcements are generally fixed on the screw holes by ultrasonic welding. Although this solves the problem of strength, it also increases the two processes of separate manufacturing and welding of reinforcements and the equipment for completing this process, which consumes time and energy, and the cost of equipment is high. and affect production efficiency
