Abstract
一种高安全长寿命铝电解电容器盖板，目的在于提供一种高安全长寿命铝电解电容器盖板。包括有盖体和卸压阀，盖体上有一个卸压阀孔，卸压阀镶装于该孔中，其特征在于；盖板上还有一个金属弹性封片，该金属弹性封片与卸压阀孔相配，其外径略大于卸压阀孔，并压装于卸压阀孔上的卸压阀外侧。金属弹性封片将卸压阀卡压在卸压阀孔内。
A high-safety and long-life aluminum electrolytic capacitor cover plate aims to provide a high-safety long-life aluminum electrolytic capacitor cover plate. It includes a cover body and a pressure relief valve. There is a pressure relief valve hole on the cover body, and the pressure relief valve is embedded in the hole. The pressure relief valve hole matches, and its outer diameter is slightly larger than the pressure relief valve hole, and is press-fitted on the outside of the pressure relief valve on the pressure relief valve hole. The metal elastic sealing sheet presses the pressure relief valve in the hole of the pressure relief valve.
Description
Technical field
The utility model relates to a kind of aluminum electrolytic capacitor cover plate, especially a kind of high-safety long-life aluminum electrolytic capacitor cover plate.
Background technology
Aluminium electrolytic capacitor comprises shell, cover plate, core bag, electrolyte, cover plate is placed on the shell aperture place, the core bag that is loaded on enclosure and electrolyte are sealed and draws both positive and negative polarity, known aluminum electrolytic capacitor cover plate includes lid and pressure-relief valve, a release valve opening is arranged on the lid, the pressure-relief valve insert is in this hole, be attached to hole wall by itself elastic force, it is less that it adheres to strength, when running into the making of external force of down when uneven (as external and internal pressure), easily coming off falls into capacitance body inside, exists potential safety hazard.And its 105 ℃ of test lifes can only reach about 5000 hours, and the life-span is shorter, and this is its shortcoming.
Summary of the invention
The purpose of this utility model is to provide a kind of high-safety long-life aluminum electrolytic capacitor cover plate.
The technical scheme that its technical problem that solves the utility model adopts is: cover plate includes lid and pressure-relief valve, and a release valve opening is arranged on the lid, and the pressure-relief valve insert is characterized in that in this hole; Also have a metallic elastic mounting on the cover plate, this metallic elastic mounting and release valve opening match, and its external diameter is slightly larger than the release valve opening, and press-fit the pressure-relief valve outside on the release valve opening.The metallic elastic mounting is pressed in the pressure-relief valve card in the release valve opening.
The beneficial effect of utility model is: the metallic elastic mounting can be carried out hermetically sealed encapsulation to pressure-relief valve, more effectively waterproof, anti-blast, prevent that the electricity paste from leaking, emit the hydrogen that electrochemistry produces, stop that forcefully various incoherent materials enter capacitor inside; Its 105 degree test life was greater than 5000 hours.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the vertical view of the utility model cover plate.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is an elasticity mounting schematic diagram of the present utility model.
Fig. 4 is an elasticity mounting left view of the present utility model.
Fig. 5 is an elasticity mounting stereogram of the present utility model.
Fig. 6 is known capacitor cover plate structural representation.
Among the figure: 1 is that lid, 2 is that pressure-relief valve, 3 is that metallic elastic mounting, 4 is that lead-out wire, 31 is the triangle convex edge.
Embodiment
Referring to accompanying drawing, the utility model includes lid 1, pressure-relief valve 2, the release valve opening is arranged in the lid 1, pressure-relief valve 2 inserts are in the release valve opening, it is characterized in that: also have a metallic elastic mounting 3 on the cover plate, this elasticity mounting and release valve opening match, and its external diameter is slightly larger than the release valve opening, and press-fit the pressure-relief valve outside on the release valve opening, the pressure-relief valve card is pressed in the release valve opening.
In embodiment of the present utility model, have convex edge 31 on metallic elastic mounting 3 peripheries as (triangle), the position at edge is thinner to strengthen its elasticity than lamellar body middle part simultaneously, is convenient to card and presses.In embodiment of the present utility model, the spring steel plate manufacturing of metallic elastic mounting 3 usefulness stainless steels, pressure-relief valve is made with silica gel or butyl rubber.
