Problems solved by technology

[0010] The present invention aims to solve the shortcomings of common power control switch interlocking structures, such as complex components, high production cost, indirect interlocking relationship, slow response of interlock stroke and many faults in the operation of power control switches, especially in solving the problems of commonly used power control switches. When the current is overloaded and overheated, it is impossible to trip off the power OFF in real time or the trip is not complete, resulting in the overheating state of the continuous circulation of the circuit; and when solving the overload and overheating, the contact shrapnel is in a semi-tripped state. When the contact shrapnel cools down Jump back to the power-on state again, continue to repeatedly power on and off to form sparks, causing dangerous problems

Embodiment Construction

[0033] In order to disclose the purpose, characteristics and effects of the present invention in detail, the present invention is described in detail as follows through the following preferred specific embodiments, in conjunction with the accompanying drawings:

[0034] As shown in Figures 1-3, it is a combined cross-sectional view of the embodiment of the present invention, which shows the state of the embodiment of the present invention when the power is OFF, the power is ON, and the contact piece is reversely bent and jumps into the power OFF OFF state; A circuit control protector, which mainly includes a box body 1, a button 2, a contact piece 3, and a linkage rod 4; wherein,

[0035] The box body 1 is hollow, with an opening above it, and at least two contact terminals are arranged on the bottom surface of the box body 1. In this embodiment, there are two contact terminals, which are respectively the first and second contact terminals 11 and 12. One end of the contact she...

Abstract

An circuit control protector which is acted by pressing a button to swing making interlinked lever moving synchronously and pulling-pashing the contact skipping to switch on or off the circuit. The characteristic of said invention is that the press button has snapping hole with extended slot, the one end of interlinked lever actively connected to contact piece and another end actively inlaid into the snapping hole, in switching on state and overcurrent, the contact piece skipped off due to deformation in heating so the circuit is in off state to insure the 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 space for free displacement; The moving rod is displaced, and the other end of the linkage rod can freely displace in the extension groove without being hindered, and the contact piece can jump off smoothly, forming a complete power-off OFF state of the circuit loop. Background technique [0002] The operation of the power control switch is mainly to perform two movement modes of power ON and power OFF of the current loop. In addition to performing the two functions of power-on and power-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 loop from not responding in real time to power-off or power-off when the current is overloaded. Danger of escape. [0003] Th...
