Abstract

The invention discloses a 40kA single-phase PCB type power surge protector. The 40kA single-phase PCB type power surge protector comprises a combined pressure-sensitive component, wherein the combinedpressure-sensitive component is provided with a low-temperature pin, a high-temperature pin and a pin component; and the 40kA single-phase PCB type power surge protector further comprises a shell used for accommodating the combined pressure-sensitive component; spring parts are arranged in the shell; the connection between the low-temperature pin and a beryllium copper shrapnel is used as a low-temperature tripping point; and two compression spring coils at the two ends of a No.1 spring serve as a public channel of remote communication signals, and torque elastic arms on a No.2 spring and a No.3 spring are respectively used as two independent poles of the remote communication signals. The 40kA single-phase PCB type power surge protector provided by the invention has the advantages of being simple in structure, high in use safety, saving the production cost and the like.

Description

technical field [0001] The invention relates to an emergency circuit protection device, in particular to a 40kA single-phase PCB type power surge protector. Background technique [0002] The surge protector is a protection device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When the electrical circuit, communication line or PCB board line is damaged by lightning or other instantaneous overvoltage, the surge The protector can play a protective role. [0003] At present, the tripping function of the PCB type surge protector is through the soft connection between the low-temperature pin and the tripping copper strip through a copper braid, and the torsion spring springs off the tripping copper strip after the low-temperature trip; there are two types of remote signal One way is to connect the copper sheet or wire to form an on-off through the micro switch, the other way is to contact the copper wire or coppe...
