Embodiment 1

[0027] see Figure 1-2 As shown, the present invention is a circuit switch with a reset function, including a fixed seat 1, a manual switch 2, a contact plate 3, a shrapnel 4, a magnetic rod 5, a telescopic spring 6, a slider 7, a fixed block 8 and a thermal resistance coil 9. The fixed seat 1 includes a manual switch cabin 101 and an automatic reset cabin 102; the manual switch cabin 101 and the automatic reset cabin 102 are separated by a baffle;

[0028] The automatic reset cabin 102 is provided with an isolation board, which divides the reset cabin 102 into a live wire room and a neutral wire room, and both the live wire room and the neutral wire room are provided with partitions, and the partition board separates the live wire room and the neutral wire room into automatic The reset chamber and the magnetizing chamber are provided with an opening at the bottom of the partition, and the contact plate 3 is an "L"-shaped plate structure. The two contact plates 3 are respectiv...

Embodiment 2

[0036] see Figure 1-4 As shown, the present invention is a circuit switch with a reset function. Its use method and working principle are as follows: press the cover to connect the shrapnel 4 to the contact plate 3, and then the circuit is turned on, and the contact plate 3 and the thermal resistance coil 9 are electrically connected, and the magnetic rod 5 passes through the middle of the thermal resistance coil 9 and the telescopic spring 6 respectively. After the power is applied, the thermal resistance coil 9 magnetizes the magnetic rod 5 due to the principle of electromagnetic induction, and the telescopic spring 6 is compressed under the action of the magnetic field. 6 is connected to the slider 7, and the telescopic spring 6 drives the slider 7, thereby causing the shrapnel 4 to increase and bend. When the temperature rises, the magnetic bar 5 demagnetizes, the telescopic spring 6 resets, the slider 7 slides, and the bending degree of the shrapnel 4 decreases. 4 is dis...

Abstract

The invention discloses a circuit switch with reset function and relates to the technical field of circuit switches. The invention includes a fixed seat, a manual switch, a contact plate, a shrapnel, a magnetic rod, a telescopic spring, a slider, a fixed block and a thermal resistance coil, a manual switch, a contact plate, a shrapnel, a magnetic rod, a telescopic spring, a slider, a fixed block and The thermal resistance coils are all set in the fixed seat, the two ends of the magnetic rod are respectively connected with the telescopic spring and the thermal resistance coil, and the two ends of the thermal resistance coil are respectively connected with the fixed block and the slider, and the fixed block and the slider are connected with shrapnel, and the shrapnel Matching with the contact plate, the contact plate is electrically connected with the thermal resistance coil. The invention increases the stability and controllability of the switch by setting the manual switch and the reset switch in series, controls the switch to close through the principle of electromagnetic induction, and resets the switch through the thermal demagnetization effect, so that the switch can be controlled according to the temperature. .

Description

technical field [0001] The invention belongs to the technical field of circuit switches, in particular to a circuit switch with reset function. Background technique [0002] At present, in order to protect the circuit, a fuse is usually installed in the circuit. After the fuse disconnects the circuit, the fuse needs to be replaced, and the waste of consumables is serious. In addition, some switches with temperature monitoring function are used to disconnect the switch through abnormal temperature monitoring. However, thermal sensing elements are generally installed, which has low reliability, complicated structure, and high cost. Contents of the invention [0003] The object of the present invention is to provide a circuit switch with a reset function, which solves the problems of complex structure and low reliability of the existing reset switch. [0004] In order to solve the problems of the technologies described above, the present invention is achieved through the fol...
