Abstract
The utility model discloses a surge protector. The surge protector comprises a housing, wherein the housing comprises an upper housing and a lower housing, which are matched in a clamped manner; a pressure sensitive resistor is arranged in the housing; an elastic piece is arranged on the lower housing; the elastic piece is connected with an insulated first plate body; at least two first through holes are formed on the first plate body; an insulated second plate body is fixedly arranged on the lower housing; two conductive insertion pieces are arranged on the second plate body in a penetrating manner; a plurality of second holes are formed on the insertion pieces; the first through holes are matched with the second holes; and a wiring post of the pressure sensitive resistor is inserted in the second holes by penetrating through the first through holes. The wiring post of the pressure sensitive resistor is clamped in the first through holes and the second holes by virtue of the elasticity of the elastic piece; and the wiring post can be loosened to replace the pressure sensitive resistor by stirring the first plate body, so that the inner pressure sensitive resistor can be continuously used after the surge protector is invalid, and therefore, the material waste is reduced.
Description
Technical field
The utility model relates to a kind of Surge Protector, and particularly the piezoresistive Surge Protector, be used for being subject to protecting household electrical appliance when thunder and lightning hits.
Background technology
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud, thunder and lightning is the Chinese medicine reason that causes electronic equipment to damage, and he threatens the safe and stable operation of the every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.Surge Protector is to be connected in parallel in circuit; prevent the device that when circuit is subject to thunder and lightning and hits, electrical equipment damaged; but in essence; Surge Protector is the device of a kind of " sacrifice oneself, protect others ", when Surge Protector suffers the lightning surge electric current; perhaps use for a long time; will inevitably occur aging and damage, at this time Surge Protector has just lost the function of protection electronic electric equipment, and impaired Surge Protector to a certain extent may cause the even short circuit of circuit middle-end.
This just needs in time to change Surge Protector; the inner critical piece of a kind of Surge Protector is piezo-resistance; be welded and fixed often between piezo-resistance and inserted sheet; and the Surge Protector inefficacy is generally pressure responsive resistor failure; be welded and fixed if adopt, if Surge Protector just damages and need to whole replacing can cause certain waste so.
Summary of the invention
The utility model is not enough for prior art, and a kind of Surge Protector is provided, and this Surge Protector is convenient for changing the piezo-resistance in it, makes the piezo-resistance of changing in it after the Surge Protector inefficacy can continue to use, the waste of minimizing material.
a kind of Surge Protector, comprise housing, described housing comprises upper shell and lower house, described upper shell and described lower house snap-fit, be provided with piezo-resistance in described housing, be provided with elastic component on described lower house, described elastic component is connected with the first plate body of insulation, be provided with at least two the first through holes on described the first plate body, be fixedly installed the second plate body of insulation on described lower house, be provided with two conductive inserts that wear within it on described the second plate body, be provided with some the second holes on described inserted sheet, described the first through hole coordinates with described the second hole, the binding post of described piezo-resistance passes described the first through hole and inserts in described the second hole.Elasticity by elastic component is clamped on the binding post of piezo-resistance in the first through hole and the second hole; can unclamp binding post replacing piezo-resistance by stirring the first plate body; change inner piezo-resistance after making Surge Protector lose efficacy and just can continue to use, reduce the waste of material.
In technique scheme, preferred, be provided with sliding tray on described lower house, described the first plate body is arranged in described sliding tray.Sliding tray is set makes the glide direction of the first plate body determine, make the chucking better effects if.
In technique scheme, described elastic component is spring.
The utility model compared with prior art; have following beneficial effect: the elasticity of the utility model by elastic component is clamped on the binding post of piezo-resistance in the first through hole and the second hole; can unclamp binding post replacing piezo-resistance by stirring the first plate body; change inner piezo-resistance after making Surge Protector lose efficacy and just can continue to use, reduce the waste of material.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1, a kind of Surge Protector, comprise housing 1, described housing 1 comprises upper shell (not shown in FIG.) and lower house 11, described upper shell and described lower house 11 snap-fit, be provided with piezo-resistance 2 in described housing 1, be provided with elastic component 3 on described lower house 11, described elastic component 3 is connected with the first plate body 4 of insulation, be provided with at least two the first through holes 41 on described the first plate body 4, be fixedly installed the second plate body 5 of insulation on described lower house 11, be provided with two conductive inserts 6 that wear within it on described the second plate body 5, be provided with some the second holes 61 on described inserted sheet 6, described the first through hole 41 coordinates with described the second hole 61, the binding post of described piezo-resistance 2 passes described the first through hole 41 and inserts in described the second hole 61.Be provided with sliding tray 7 on described lower house 11, described the first plate body 4 is arranged in described sliding tray 7, sliding tray 7 is set makes the glide direction of the first plate body 4 determine, make the chucking better effects if, in the present embodiment, described elastic component 3 is spring.
Elasticity by elastic component 3 is clamped on the binding post of piezo-resistance 2 in the first through hole 41 and the second hole 61; can unclamp the binding post of piezo-resistance 2 by stirring the first plate body 4 and change piezo-resistance 2; change inner piezo-resistance 2 after making Surge Protector lose efficacy and just can continue to use, reduce the waste of material.
