Description
Technical field
The utility model relates to varistor technical field more particularly to a kind of excurvation foot type varistors.
Background technique
Varistor is a kind of votage limit type protection device, using the nonlinear characteristic of varistor, when overvoltage appears in
Two interpolars of varistor, varistor can be by voltage clampings to a relatively-stationary voltage value, to realize to rear class
The protection of circuit.
Currently, varistor is commonly straight feet shape product, this straight feet class shape varistor product ontology height is not easy to control
Unanimously, plug-in unit positions on unfavorable pcb board, and in addition varistor does not have explosion-proof function, and overheat hair is easy in voltage breakdown
Raw burning, damages circuit and other elements on pcb board.
Utility model content
It is not easy to control and anti-flaming purpose of the utility model is to solve varistor height exists in the prior art
Disadvantage, and a kind of excurvation foot type varistor proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of excurvation foot type varistor is designed, including round resistance hinders core, the circle resistance hinders on core two sides
Soldering has an electrode slice, and soldering has an excurvation pin on each electrode slice side, and the excurvation pin includes inner end and external
End, the inner end and external connection end junction are equipped with bending part, and the electrode slice is coated with epoxy skins, the epoxy
Be equipped on the outside of resin surface layer and be sleeved on internal explosion-resistant enclosure, the explosion-resistant enclosure bottom is equipped with reinforcing portion, explosion-resistant enclosure with
Cushioned material layer is filled between epoxy skins, the padded coaming layer surface is bonded with flame-retardant layer.
Preferably, the bending part curves inwardly in the horizontal direction.
Preferably, the cushioned material layer is polyethylene foams layer.
Preferably, the flame-retardant layer is silicon rubber flame-retardant oxidant layer.
The utility model proposes a kind of excurvation foot type varistor, beneficial effect is:
1, it by the way that explosion-resistant enclosure is arranged on the outside of epoxy skins, then fills out between explosion-resistant enclosure and epoxy skins
The cushioned material layer for filling surface setting flame-retardant layer, can play explosion-proof and fire-retardant effect, prevent the breakdown generation of varistor quick-fried
Circuit and other elements on pcb board are damaged after splitting；
2, bending part is set between the inner end and external connection end of excurvation pin, plays outside when client plug-in pcb board uses
The bending part of curved pin snaps on pcb board, facilitates Client card is unified to position, carries out automation part mate with benefit.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of excurvation foot type varistor front section view；
Fig. 2 be the utility model proposes a kind of excurvation foot type varistor side sectional view.
In figure: round resistance hinders core 1, electrode slice 2, excurvation pin 3, inner end 31, bending part 32, external connection end 33, asphalt mixtures modified by epoxy resin
Rouge surface layer 4, explosion-resistant enclosure 5, reinforcing portion 6, cushioned material layer 7, flame-retardant layer 8.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of excurvation foot type varistor, including round resistance hinder core 1, and round resistance hinders 1 two sides of core
