Circuit control protector

Abstract

In the protector, a push button is movable pivot jointed to opening of box body. One end of push button is extended to bunt one end of a contact piece, and the other end of the push button is inner pivot jointed to an interlock piece. The interlock piece makes pivot joint axis possible to be rotated and swung to the push button relatively. End part of the interlock piece is bunted to the other end of the contact piece. Swing caused by pressing push button makes one extended end of push button drive one end of a contact piece, or makes the other end of the interlock piece eject the other end of the contact piece so that two ends of the contact piece are bounced up and down. Thus, on / off states of circuit loop are formed. When push button is in on state, the contact piece is not restricted by the interlock piece, or the contact piece can be bounced freely. Therefore, if current is overloaded, the contact piece is inverted bounced caused by heat so as to form off state of circuit.

Description

technical field [0001] The invention relates to a circuit-controlled protector structure. A button is swung at a pivot joint, and the left and right ends of the button are respectively pushed against the two ends of a contact piece, so that the two ends of the contact piece jump up and down to form a circuit loop. The power-on (ON) or power-off (OFF) state; and when the button is in the position of circuit conduction (ON), the button does not restrict the contact piece, so that the contact piece can jump off freely. When the current is overloaded, the contact piece is heated and deformed. Reverse bouncing, forming a power-off (OFF) of the circuit loop. Background technique [0002] Press, various commonly used switch structures are too numerous to enumerate. The operation of the switch structure of the power supply mainly lies in the two actuation strokes of power on (ON) and power off (OFF). Therefore, buttons, linkage components and elastic contact pieces The linkage rela...

AI Technical Summary

Problems solved by technology

[0004] (a) The structure of the components inside the switch is complicated, time-consuming to assemble, the actuation stroke is not simple and the production cost is increased

[0005] (b) Improper configuration of the interlocking components, resulting in the bending and jumping of the elastic contact piece cannot be positioned on one side, and the switch is unreliable when performing power-on (ON) or power-off (OFF)

[0006] (c) When the current overload trips, the elastic contact piece cannot be reliably tripped and is positioned at the power-off (OFF) position. When the elastic contact piece cools down, it may jump back to the power-on (ON) state, which cannot effectively protect the current overload state. Electrical Safety

[0007] (d) After the current overload trips, it cannot be directly linked, so that the key or button is returned to the power-off (OFF) position, which is not conducive to user identification and operation
