Circuit control protector

Abstract

Pressing a button causes wobble, making control lever act synchronistically. Pushing and pulling a contact piece causes flop so as to make loop form on / off state. Characters are that the button subassembly is connected to control bar, where there is a clamping slot. The clamping slot holds the contact piece movably. Pressing the button moves the control lever. The clamping slot of the control lever pushes and pulls the contact piece. The contact piece flops and is bent to two sides so as to form on / off state of circuit. When the button is in 'on' position, if current is over loaded, then the contact piece can be deformed so as to jump up to breakaway contact. Thus, the circuit is in 'off' state in order to guarantee safe power utilization.

Description

technical field [0001] The invention relates to a circuit control protector. Background technique [0002] The operation of the power control switch is mainly to perform two action strokes 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, so as to prevent the fuse or breaker of the current circuit from not responding in real time when the current is overloaded. Risk of blackout or tripping. [0003] There are too many patent cases for various known power control switches, such as US Patent No. 5,262,748 filed by the applicant himself, and other US Patent Nos. 4,167,720, 4,937,548, 5,223,813, 5,451,729, and 5,558,211. .. etc. are too numerous to enumerate, but all these patents have common shortcomings as follows: [0004] (1) There are many interloc...

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 actuation relationship is not accurate, which increases the chance of failure, which is not conducive to the safety considerations of consumers.

[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 continues to repeatedly energize and power off to form sparks, causing danger; and the electronic and electrical equipment in the current loop Due to repeated power-on and power-off, it crashes or fails to operate normally, shortens the service life, or even damages it so that it cannot be used
