The utility model discloses compact structure, the miniaturized requirement of adaptation complete machine, provide safe, reliable lightning protection or overvoltage protection can for miniaturized equipment.
Description
Technical field
The utility model relates to overvoltage, anti-thunder technical field, especially a kind of on-board lightning-protection module on pcb board.
Background technology
Along with electronic equipment is day by day miniaturized; originally plug-in (or track installation formula) surge protector because of space large; more and more inadaptable compact apparatus requirement day by day, and traditional varistor is not because having the safeguard measures such as aging, inefficacy, easily brings potential safety hazard to equipment use.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of on-board lightning-protection module, provide safe and reliable lightning protection or overvoltage protection to compact apparatus.
The utility model solves the technical scheme that its technical problem adopts: a kind of on-board lightning-protection module, is installed on pcb board, comprises shell, is provided with two varistors in described shell; Two described varistors respectively have a pin to be connected with power end; Two varistors other pin is separately connected with one end of gas discharge tube respectively by hot disconnector; The other end of described gas discharge tube is connected with earth terminal; Described hot disconnector is two independently energy storage type bouncing mechanisms, and described energy storage type bouncing mechanism comprises slide bar; One end cover of described slide bar has energy-stored spring; Sheet metal is embedded with in the middle part of slide bar.
Further, another proper right enclosure of slide bar described in the utility model is equipped with sensitive switch; Sensitive switch can be touched like this after hot disconnector action and provide alarm signal.
Further say, shell described in the utility model is square plastic shell.
Further say, sheet metal described in the utility model is U-shaped sheet metal; A described varistor other pin is separately connected with U-shaped sheet metal respectively by soldering.
The beneficial effects of the utility model are, solve the defect existed in background technology, compact conformation, adapt to complete machine small form factor requirements; Safe and reliable lightning protection or overvoltage protection can be provided to compact apparatus.

Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of on-board lightning-protection module as Figure 1-5, is installed on pcb board, comprises square plastic shell 4, is provided with two varistors 1 in square plastic shell; As shown in Figure 3, two varistor 1 stacked on top of one another are placed; Two varistors respectively have a pin to be connected with power end L and N; The respective other pin of two varistors 1 is connected with one end of gas discharge tube 3 respectively by hot disconnector 2; The other end of gas discharge tube 3 is connected with earth terminal PE;
Hot disconnector 2 is two independently energy storage type bouncing mechanisms, two independently energy storage type bouncing mechanism respectively separately corresponding varistors 1; Energy storage type bouncing mechanism comprises slide bar 5; One end cover of slide bar has energy-stored spring 6; Sensitive switch 8 is equipped with in another proper right square plastic shell 4 inside of slide bar; Sensitive switch can be touched like this after hot disconnector action and provide alarm signal.
U-shaped sheet metal 7 is embedded with in the middle part of slide bar 5; A varistor other pin is separately connected with U-shaped sheet metal respectively by soldering.When Faulty MOV damages, fusing scolding tin, hot disconnector action, can be disconnected from the circuit lightning-protection module.
The just embodiment of the present utility model described in above specification, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
