Abstract
The utility model discloses a button starting type surge protector, comprising a housing, a control spring and a locating lever; the inner of the housing is provided with a separating driving rod, a fuse link and a pressure-sensitive resistor fixedly welded to the fuse link through low melting point alloys; the separating driving rod and the pressure-sensitive resistor movably abut. The characteristics are that a guide rail is arranged in the housing; the inner side of the guide rail is provided with a temperature-sensitive elastic sheet clamping projection; the locating lever is provided with a groove; the locating lever is movably arranged in the guide rail; the housing is provided with a button in connection with the locating lever; the locating lever is driven by the button to move in the guide rail and to drive the separating driving rod to depart from the pressure-sensitive resistor, and the groove of the locating lever is clamped on the temperature-sensitive elastic sheet clamping projection. The button starting type surge protector has the characteristics of simple structure, fast and convenient use, good use stability, strong applicability and good use reliability.
Description
Technical field
The utility model belongs to surge protection technical field, is specifically related to a kind of pushbutton enable type surge protector.
Background technology
Surge protector is a kind of conventional low voltage protection device for electrophonic, it is by housing, piezo-resistance, releasing structure and the conductive electrode being arranged on housing form, under normal circumstances, it is in high impedance status, when having thunderbolt or overvoltage, its conducting within the utmost point short time is introduced the earth by thunder and lightning or overvoltage by ground wire, thereby reach the effect of protective circuit, prior art surge protector structure is comparatively simple, it is also comparatively convenient to use, but when long-time use, its releasing structure sensitivity meeting declines and then affects stability in use and the reliability of surge protector, applicability is restricted to a certain extent, be difficult to meet the needs in market.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the pushbutton enable type surge protector that stability in use is good and reliability is strong.
The technical scheme that realizes the utility model object is a kind of pushbutton enable type surge protector, comprise housing, be arranged on the control spring in described housing, be connected with described control spring and be arranged on the backstay on housing, in described housing, be provided with separation drive rod, the piezo-resistance that is also provided with fuse link and is welded and fixed by low-melting alloy with described fuse link in described housing, described separation drive rod and described piezo-resistance activity butt, in described housing, be provided with guide rail, in described guide rail inner side, be provided with temperature-sensitive shell fragment screens projection, described backstay is provided with groove, described backstay is movably arranged in described guide rail, on described housing, be provided with the button being connected with described backstay, described backstay under the promotion of described button, in guide rail, move and drive separate drive rod leave piezo-resistance and described backstay groove screens in described temperature-sensitive shell fragment screens projection.
On described separation drive rod, be provided with insulating barrier, described insulating barrier is arranged on and separates between drive rod and piezo-resistance.
In described fuse link, be provided with anti-sclerosis gap.
On described housing, be provided with inspection hole, He Hong indicator, green indicator on described backstay, described red indicator is arranged on the outer end of described green indicator, matches with described inspection hole green indicator in described green indicator described in described backstay screens is during at described guide rail.
The utlity model has positive effect: of the present utility model simple in structure, convenient to use, be provided with guide rail and button, when it uses, start button moves forward backstay, and backstay is positioned in temperature-sensitive shell fragment screens projection, synchronously make to separate drive rod away from piezo-resistance, when having thunderbolt or overvoltage, the temperature of piezo-resistance raises, piezo-resistance and fuse link are disconnected, the projection of temperature-sensitive shell fragment screens is simultaneously subject to temperature that deformation also occurs, backstay is resetted under the restitution of spring, and then drive the reset of separation drive rod to compress piezo-resistance, piezo-resistance and fuse link are disconnected completely, its stability in use is good, applicability is strong, dependability is good.
