Abstract

The invention provides a surge protector, which comprises a shell body, a first insulating sleeve, an aluminum sheet, a piezoresistor chip, a metal connecting terminal, a second insulating sleeve, a spacer and a clamp spring, wherein the first insulating sleeve is arranged inside the shell body, the aluminum sheet is arranged inside the first insulating sleeve, the piezoresistor chip is arranged on the aluminum sheet, the metal connecting terminal is arranged on the piezoresistor chip, the second insulating sleeve sleeves the metal connecting terminal, the spacer and the clamp spring are arranged on the second insulating sleeve, the piezoresistor chip is accommodated in the first insulating sleeve, the middle part of the metal connecting terminal forms a step part, the second insulating sleeve comprises a first sleeve, a second sleeve and a connecting ring, the first sleeve sleeves the step part of the metal connecting terminal, the second sleeve is arranged below the step part, the connecting ring is connected between the first sleeve and the second sleeve, the outer side of the second sleeve is pressed against the inner wall of the shell body, the metal connecting terminal is sleeved with a first lantern ring and a second lantern ring, the outer periphery of the lantern rings are each presses against the inner wall of the first sleeve or the second sleeve, the clamp spring is arranged on the second insulating sleeve, and the outer side of the clamp spring is clamped inside the shell body. The surge protector has the internal and external sealing effects, and achieves the dustproof and the like purposes.

Description

technical field [0001] The invention relates to a surge protector. Background technique [0002] Due to external or internal reasons, there will be surges in most circuits. The existence of surges will affect the stability of the circuit to a certain extent, and it will also cause certain damage to electrical appliances. In order to reduce the existence of surges, the general circuit Surge protectors are installed in all cities to protect various electrical equipment in the low-voltage power distribution system from damage caused by lightning overvoltage and operating overvoltage. [0003] Existing surge protectors are poorly sealed and do not have waterproof, dustproof and anti-corrosion properties. Under harsh environmental conditions, they may be affected by environmental factors, and the interior of the surge protector may be eroded by dust and liquid, causing the surge protector to is not working properly. Contents of the invention [0004] The invention provides a ...
