Description

switch

technical field

The utility model relates to the technical field of power switches, in particular to a switch.

Background technique

A switch is a common control element that controls power on and off. The switch in the prior art includes a switch mounting frame, a panel, etc. The switch mounting frame in the prior art includes an iron plate and a plastic outer frame, both of which are fixed by bonding, so the fixation is not very firm, and the two are easy to fall off during use, which leads to The service life is shorter.

Contents of the invention

The technical problem to be solved by the utility model is to provide a switch with a long service life.

The technical solution adopted by the utility model is: a switch, including a switch installation frame, the switch installation frame includes an iron plate and a plastic outer frame arranged around the iron plate, and the iron plate is provided with a plurality of installation positioning holes , the plastic outer frame is provided with a plurality of positioning blind holes, and the iron plate and the plastic outer frame are integrally formed by an injection molding machine.

Compared with the existing technology, the utility model has the following advantages: the iron plate and the plastic outer frame are integrally formed by the injection molding machine, so that the two are more firm, and it is not easy to fall off during use, thereby extending the service life of the switch longer.

Preferably, a circle of slopes is provided at the openings of the plurality of positioning blind holes. Because the blind hole also needs to be molded by the injection molding machine, it is easy to cause the blind hole to shrink, so setting a slope at the opening of the blind hole can effectively prevent the shrinkage of the blind hole, making the injection molding effect better.

Preferably, the installation and positioning holes are waist-shaped through holes, and the installation and positioning holes are respectively located on four sides of the iron plate. In this way, the firmness of the iron plate is higher after installation.

Preferably, the plastic outer frame is further provided with a plurality of reinforcing ribs. In this way, the strength of the plastic outer frame is set to be higher.

Preferably, the reinforcing rib is arranged around the positioning blind hole. This results in higher strength around the blind hole.
