Problems solved by technology

[0010] The present invention aims to solve the shortcomings of various known power control switch interlocking structures, such as complicated components, high manufacturing cost, indirect interlocking relationship, slow response of interlocking strokes, and many faults in the operation of power control switches. When the power control switch is overloaded and overheated, it cannot be tripped off in real time (OFF), tripped off or incomplete, resulting in an overheated state where the circuit continues to flow; 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 dangerous problems

Embodiment 2

[0056] The operation actions, linked actions, and achieved effects of the second embodiment are completely the same as those of the aforementioned embodiments.

[0057] refer to Figure 8 , when the button 2 is in the position of circuit conduction (ON), the end of the linkage 22 of the button 2 is located on the right side of the elastic piece 32 of the contact piece, and the extension rod 221 of the linkage 22 is in contact with the ring of the box body 1 There is still a distance between the right sides of the ladder 14, which provides a free displacement space for the extension rod 221 of the linkage 22, so that the end of the linkage 22 will not touch the elastic piece 32 that limits the contact piece 3 , when the current is overloaded, the contact piece 3 and the contact portion 31 are heated and deformed to reversely bend and bounce, the free end of the contact piece 3 is downward, and the free end of the contact portion 31 is bounced upward, so that the first contact p...

Abstract

The invention relates to a circuit control protector, wherein one knob is axially mounted at the opening of box, while one end of knob downwards extends to contact one end of contact plate, and another end of knob is axially connected to a linked element whose one end is arranged with extending rod; said linked element contacts another end of contact plate; the box has one cycle path; the extending rod is inserted into the cycle path to displace and position along the ring; via pressing the knob to rotate it, one end of knob pushes one end of contact plate, and the linked element at another end of knob pushes another end of contact plate, to make two ends of contact plate move up-and-down, to form the power-on or power-off states of circuit; when the knob is at the position that the circuit is power one, the pushing element do not contact and limit another end of contact plate, to make it freely jump; when the current is over, the contact plate is heated and deformed to jump reversed to cut off the circuit.

Description

technical field [0001] The invention relates to a protector controlled by a circuit. By pressing the button to swing, the push button pushes the contact piece, so that the two ends of the contact piece jump up and down, forming the power-on (ON) or power-off (OFF) state of the circuit loop; when the button is in the circuit In the conduction (ON) position, the button does not touch the limit contact piece. When the current is overloaded, the contact piece is heated and deformed and reversely bends and bounces, reaching the tripping and power-off (OFF) of the circuit circuit. Background technique [0002] The operation of the power control switch is mainly to perform two actuation 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, so as to prev...
