Magnetic electric power control switch with high heat dissipation

Abstract

The invention discloses a magnetic electric power control switch with high heat dissipation, which comprises a shell, and is characterized in that a groove at the middle of the bottom of the shell is provided with a dust screen in a matched manner, both the left and the right of the groove are provided with a static contact, the middle of each static contact is provided with an insulation box at the inner side of the shell, the top of the shell is vertically provided with a push rod in a sliding and sealing manner at the middle position, the top end of the push rod is provided with a limiting cap, the bottom end of the push rod is provided with a pressing plate inside the shell, the outer ring of the top of the pressing plate is provided with an iron block, the top of the iron block is provided with a magnetic coil on the top inner wall of the shell, a motor mounting base at the middle of the bottom of the pressing plate is provided with a motor, an output shaft of the motor is provided with fan blades, both the left and the right of the bottom of the pressing plate are provided with a support rod, the bottom ends of the two support rods are provided with a metal grid piece in a bridging manner, both the left side and the right side of the bottom of the metal grid piece are provided with a moving contact, and both the left end and the right end of the metal grid piece are provided with a spring. The magnetic electric power control switch with high heat dissipation is safe, reliable, good in heat dissipation performance and capable of effectively prolong the service life of the switch.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a magnetic high heat dissipation power control switch. Background technique [0002] The word switch is interpreted as turning on and off, but it also refers to an electronic component that can open a circuit, interrupt the current flow, or cause it to flow to other circuits. The most common switches are human-operated electromechanical devices that have one or more electrical contacts. The "closed" of the contact means that the electronic contact is conducting and allows the current to flow; the "open" of the switch means that the electronic contact is not conducting and forms an open circuit, and the current is not allowed to flow. The power switch in the prior art has poor structural stability, poor sealing and heat dissipation, and lacks a reasonable and effective buffer device when the switch is opened and closed, and the internal parts of the switch are severely wor...

AI Technical Summary

Problems solved by technology

The power switch in the prior art has poor structural stability, poor sealing and heat dissipation, and lacks a reasonable and effective buffer device when the switch is opened and closed, and the internal parts of the switch are severely worn, which affects the service life of the switch. In addition, the existing The self-protection device of the power switch is not perfect, and the disconnection protection cannot be performed in time, which delays the fault handling time and causes additional property loss
