Abstract

The invention discloses a surge protection module, which includes a piezoresistor; also includes a shell, an assembly case, a welding piece, a welding pin, a first electrode piece and a metal pressure piece; one side of the assembly case is provided with The first groove, the welding piece, the piezoresistor and the first electrode piece are stacked in the first groove in sequence, and the welding piece is located at the bottom; the metal pressing piece is compressed by a detachable connection The first electrode sheet in the first groove, so that the welding sheet and the first electrode sheet are respectively attached to the two sides of the piezoresistor; the side of the welding sheet is provided with a boss, and the bottom of the first groove is provided with a boss. There is a gap exposing the boss, and one end of the welding pin is welded to the boss to form a tripping point at the welding connection point. The invention avoids the problem that heat is absorbed by the varistor during welding, strengthens the protection of the electrical performance of the varistor, and at the same time alleviates the problem of limited use.

Description

A surge protection module technical field

[0001] The present invention relates to the field of surge protectors, in particular to a surge protection module. Background technique SPD refers to surge protector, also called lightning protector, which is a kind of surge protector for various electronic equipment, instrumentation, communication Electronic devices for safety protection. When an electrical circuit or communication line suddenly generates a spike current or The surge protector can turn on the shunt in a very short period of time, so as to avoid the damage of the surge to other equipment in the circuit. Harmful.

[0003] The on-board SPD tripping structure commonly used in the market is an integrated structure, and its tripping principle is a varistor. The low-temperature solder joints of its pins are heated by current to melt the low-temperature solder joints to achieve the tripping purpose of automatic separation of the pins. In the existing tripping str...
