Abstract

The invention provides a surge protector which comprises a machine seat capable of being fixed on a guide rail and a pluggable module capable of being inserted into the machine seat, wherein the pluggable module comprises a cover-shaped module shell, a first printed circuit board, a second printed circuit board and a module bottom cover, wherein the first printed circuit board and the second printed circuit board are relatively arranged in the module shell in parallel, a necessary current leakage distance and an air distance are formed between the first printed circuit board and the second printed circuit board, and the first printed circuit board and the second printed circuit board are respectively provided with claw pieces used for being connected with rows of wiring terminals; the module bottom cover is inserted into the bottom end of the module shell, is provided with positioning grooves used for fixing the first printed circuit board and the second printed circuit board and allowing the claw pieces to extend out; the machine seat comprises a machine seat shell and a grounding contact, wherein through grooves for allowing the claw pieces to pass through are formed in the top of the machine seat shell, and a connecting module connected with the claw pieces is arranged inside the machine seat shell; the grounding contact is inserted into the bottom end of the machine seat shell to fix the machine seat shell and the guide rail; the grounding contact comprises grounding metals connected with the claw pieces in the first printed circuit board and the second printed circuit board. The surge protector provided by the invention can be used for restraining surge on a line in the structure of rows of wiring terminals.

Description

technical field [0001] The invention relates to the technical field of protection devices for appliances and equipment, in particular to the technical field of facility protection electronic components, and in particular to a surge protector. Background technique [0002] Surge protector is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. [0003] Surge protection device (Surge protection Device) is an indispensable device in the lightning protection of electronic equipment. It used to be called "lightning arrester" or "overvoltage protector". The English abbreviation is SPD. The function of the surge protector is to limit the ins...
