Abstract
The utility model discloses an explosion-proof housing of a varistor, which comprises a housing and a housing cover, wherein a positioning cavity for placing the varistor is arranged on the bottom of the housing, and is provided with a step face which is contacted with the varistor, one side of the housing is provided with a butt lateral wall face A and a butt lateral wall face B which is correspondingly integrated with the housing cover, and the lateral wall face A and the lateral wall face B can form a complete lateral wall face after the butt joint, and lead grooves for freely placing the pins of the varistor are arranged on the butt end faces of the lateral wall face A and the lateral wall face B. The explosion-proof housing can prevent the fragments from flying when the varistor explodes, can effectively inhibit open fire, and has simple and stable housing and convenient operation.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment of electronic devices and components, relates in particular to a kind of explosion-proof shell of varistor.
Background technology
Varistor is as a kind of pulse Surge Protector; in the circuit that reality is used; because varistor is to use epoxy resin enclosed; when product in the protection process, be subjected to moment forceful electric power press or the impact of heavy current and breakdown easily or hit and split when losing efficacy, fragile other devices of product packaging layer and porcelain body fragment cause entire circuit to lose efficacy.Damage device when preventing that the explosion fragment from flying to split, use a kind of shell that the piezo-resistance assembling is used.For preventing the situation of piezo-resistance product in aging back explosion, common methods has following several at present: put a kind of insulation rubber tube on the piezo-resistance product of having sealed, this method is up and down an emptying aperture, and effect is not good enough.Load onto the phenolic resins shell at the piezo-resistance product of having sealed, the high/low-temperature impact defectiveness of this shell, and because enclosure structure assembling back product is loosening, the plate effect is not good enough.
The content of utility model
The utility model technical issues that need to address provide a kind of assembling shell that fragment flies to split when preventing the varistor explosion.
The technical problems to be solved in the utility model is achieved through the following technical solutions: a kind of explosion-proof shell of varistor, comprise housing and cap, described housing bottom has the localization cavity of placing varistor, and described localization cavity is provided with the step surface that contacts with varistor; In a side of housing butt joint side wall surface A is arranged, corresponding and cap are connected as a single entity docks side wall surface B, and side wall surface A, B butt joint constitutes the complete side walls face, is provided with the lead-in wire groove that energy freely be placed the resistor pin at side wall surface A, B butt joint end face.Earlier varistor is pressed into the localization cavity step surface in the housing during assembling, varistor just periphery contacts with step surface, the resistor bottom is unsettled with the housing bottom surface, when reducing the resistor explosion greatly to the impulsive force of shell, increase the storage space of resistor fragment simultaneously, the lead-in wire of resistor is freely put into the lead-in wire groove, and the cap that closes moves explosion-proof shell and causes the manual type stamping machine and press down closely and close.
Further: in above-mentioned explosion-proof shell, described localization cavity integral body is circular, and for the step surface that makes localization cavity can well contact with the periphery of varistor, this localization cavity also can be designed to adapt to the different shape of resistor profile certainly.Be evenly equipped with the inserting column hole between the described localization cavity outside and the shell wall.Position corresponding with the housing localization cavity in the described cap is provided with reference column, and the position corresponding with housing inserting column hole is provided with inserting column, and the inserting column of cap is inserted in the inserting column hole of aiming at housing, and it is tightr to make that housing engages with cap.Also be distributed with the air-vent that is used for heat extraction on described butt joint side wall surface A, the B face, in the time of can reducing the resistor explosion to the thermal shock power of shell.Described housing is a kind of in square column type, cylindrical, the elliptical cylinder-shape, and preferred case design is a square column type.Described housing mouth be provided with the contacted step in cap edge to the edge that heals up, cap can be connected on the housing mouth, explosion-proof shell is moved to cause the manual type stamping machine and press down closely and close again.
The advantage that the utility model is compared with prior art had is: fragment flew to split when this explosion-proof shell can prevent the varistor explosion, can effectively suppress naked light and shell structure is simply firm, and is easy to operate.
