The stable development of a little industries, has promoted the growth in thin film capacitor market.Thin film capacitor in the long-term use, inside it
It can produce compared with atmospheric pressure, if discharged not in time, security risk can be caused.
The content of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided it is a kind of it is rational in infrastructure, pressure release effect is good
Thin film capacitor anti-explosion mechanism.
To achieve the above object, technical solution provided by the utility model is：Thin film capacitor anti-explosion mechanism, it includes
There is the core of shell and installation inside the shell, cover top portion is equipped with head cover, and head cover is equipped with pole foot, and pole foot bottom passes through shell
It is connected with core, pole foot top extends the connecting pin to form U-shaped, and pole underfooting portion forms the connecting shaft of cylinder, connecting shaft top
Extension forms spacing ring, forms card slot between connection foot bottom at the top of spacing ring, pole foot is installed on head cover by card slot, even
Pressure release passage is equipped with spindle, pressure release passage outlet is located at the outer circumferential surface of connecting shaft positioned at connection foot bottom, pressure release passage entrance
Lower part, is set with sealing ring, sealing ring inner ring surface and pressure release passage inlet contact shape in the connecting shaft on the outside of pressure release passage entrance
Into sealing, the connecting shaft between sealing ring and spacing ring is equipped with pressure release spring, and pressure release spring one end is connected with spacing ring, another
End is connected with sealing ring.
The pressure release passage is two, respectively positioned at connecting shaft both sides.
The sealing ring makes shaping using elastomeric material.
The pole underfooting portion is set with insulation sleeve, and insulation sleeve makes shaping, insulation sleeve bottom and top using elastomeric material
Tops contradict, and insulation sleeve lower part is equipped with exports matched bleeder port with pressure release passage.
The utility model, when the hypertonia in capacitor, pushes up sealing ring after using the above scheme, sealing
Circle extruding spring exposes pressure release passage entrance, and air pressure is discharged by pressure release passage, and when pressure is normal, sealing ring is in pressure release spring
Under the action of pressure release passage entrance is sealed, it is good using rational in infrastructure, the pressure release effect after this programme.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Embodiment
With reference to all attached drawings, the utility model is described in further detail, and the preferred embodiment of the utility model is：Ginseng
