Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic switches, in particular to an electromagnetic switch housing. Background Art

[0002] An electromagnetic switch is an electrical component that uses electromagnetic force to control the on / off of a circuit. It relies on the magnetic field generated by the electromagnetic coil when energized, attracting the core and other movable parts, thereby closing or opening the contacts, thereby connecting, disconnecting, or switching the circuit.

[0003] The electromagnetic switch housing is an indispensable part of the electromagnetic switch. It is the outer shell of the electromagnetic switch and is a structural component that contains and protects the internal components of the electromagnetic switch. It is usually made of metal or engineering plastics.

[0004] Most electromagnetic housings on the market are closed. Since the housings are usually closed or semi-closed structures, it is difficult for heat to dissipate quickly. If the heat cannot be dissipated in time, it may cause the insulation layer of the electromagnetic coil to age faster, reduce its insulation performance, and even cause short circuit failures. The existing technology is to dissipate heat by increasing ventilation and installing fans. The heat dissipation effect is good, but the internal dust accumulates too quickly, causing the contact area to affect its insulation performance. When the contacts are disconnected, they are in a completely insulated state, and it is difficult to disassemble and clean the dust. Especially for people who are not familiar with the structure and disassembly process of electromagnetic switches, it takes a lot of time to find all the fixing points and remove them one by one.
