Circuit control protector

Abstract

The invention discloses a circuit control protector, which is characterized by the following: setting a lock joint hole with extension groove on the button; inserting one end of interlocking rod in the lock joint hole movably; connecting the end of interlocking rod with contact piece; swaying through pressing button to synchronize the movement of interlocking rod; jumping the contact piece through pulling and pushing to form power on or off condition for circuit loop. When the button lies at circuit on position, the extension groove of lock joint hole provides space to move freely for interlocking rod end; when the current is overloaded, the contact piece deforms due to heat and bounds inversely, which pushes the interlocking rod move freely in the extension groove without baffling by button. The contact piece can jump successfully to form power off freely, which guarantees power safety.

Description

technical field [0001] The invention relates to a circuit control protector, which is provided with an extended groove between the button and the linkage rod to provide a free displacement space for the linkage rod; when the current is overloaded, the heat deformation of the contact piece reverses Bouncing, the contact piece pushes the linkage rod to move, and the end of the linkage rod can move freely in the extension groove without hindrance, and the contact piece can jump off smoothly, ensuring the freedom of the circuit circuit when the current is overloaded. Trip power off (OFF). Background technique [0002] The operation of the power control switch is mainly to execute the two action processes of power-on (ON) and power-off (OFF) of the current loop. In addition to performing two functions of power-on (ON) and power-off (OFF), many current switch structures also have the function of automatically tripping and power-off when the current is overloaded and overheated, s...

AI Technical Summary

Problems solved by technology

[0004] 1) There are many linked components, and the linked stroke is complicated, resulting in a non-real-time action relationship between the button and the terminal component, which also increases the manufacturing cost

[0005] 2) The action relationship is not accurate, which increases the chance of failure, which is not conducive to the safety of consumers and electricity use

[0006] 3) When the current overload circuit is overheated, the contact shrapnel cannot trip off the power in real time or the trip is incomplete, so that the circuit is still in the current conduction state, and the circuit continues to overheat and cause danger

[0007] 4) When the current overload circuit is overheated, the contact shrapnel is in a semi-tripped state, and when the contact shrapnel cools down, it jumps back to the energized state, and sparks are formed after repeated power-on and power-off, causing danger; and the electronic and electrical equipment in the current loop are due to Repeated power-on and power-off, and the machine crashes or fails to operate normally, shortening the service life, and even damages it so that it cannot be used
