Magnetic electric power control switch with high heat dissipation

Abstract

The invention discloses a magnetic power control switch with high heat dissipation, which comprises a housing, and a dust-proof net is arranged in the middle groove of the bottom of the housing, and static contacts are arranged on the left and right sides of the groove. The middle part of the head is provided with an insulating box on the inner side of the shell, and the middle position of the top of the shell is vertically slid and sealed with a push rod, the top of the push rod is provided with a limit cap, and the bottom end of the push rod is provided with a pressure plate inside the shell , the top outer ring of the pressure plate is provided with an iron block, the upper part of the iron block is provided with a magnetic coil on the top inner wall of the housing, the motor is installed on the middle motor mounting seat at the bottom of the pressure plate, and the output shaft of the motor is provided with a fan blade, the pressure plate There are struts on the left and right sides of the bottom of the pole, metal grids are provided across the bottom ends of the two struts, moving contacts are set on the left and right sides of the bottom of the metal grid, and the left and right ends of the metal grid There are springs. The invention is safe and reliable, has good heat dissipation performance and effectively prolongs 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
