Description
Technical field
The utility model system have about a kind of closing component and and Winding-type solid electrolytic capacitor, espespecially a kind of closing component and and Winding-type solid electrolytic capacitor being suitable for sound equipment electricity container.
Background technology
In audible component, capacitor (capacitor) is widely used in smothing filtering, reciprocal cross company, high frequency compensation, provides the purposes such as direct current back coupling.And capacitor is divided into quite a lot of type according to structure and processing procedure mode, but in the acoustic system, because characteristic such as special requirement big current, response frequency etc., therefore the most extensively transporting user is in the acoustic system aluminium matter electrochemical capacitor.
As shown in figure 12, the Winding-type solid electrolytic capacitor commonly used includes: capacitor casing 1, capacitor element 2 and a closing component 3.Wherein one end of capacitor casing 1 has an openend, and this closing component 3 is arranged at this openend, and forms good obturation effect with this openend, capacitor element 2 groups to be stood on the inside of this capacitor casing 1.Capacitor element 2 is connected with two-terminal 4 and is welded on circuit substrate by two-terminal 4.
This capacitor element 2 is by an anode foils and negative foil roll around forming, and is formed with dielectric substrate between anode foils and Cathode Foil.This capacitor element anode foils and Cathode Foil are oxidized by metallic film to form dielectric layer, or utilize the mode of conductive layer on insulating polymer material evaporation to make, there is dielectric film or insulation film, to make to form insulation between the negative electrode and positive electrode of capacitor between anode foils and Cathode Foil.
General capacitor adopts reflow mode to be welded on circuit substrate, and when capacitor welding, capacitor must lead to hyperthermal soldering furnace, therefore makes capacitor also must bear high temperature.Inside due to capacitor casing 1 is closed environment, add capacitor element 2 packaged in housing containing being soaked with electrolyte, and in order to promote the macromolecular material of insulating properties, easily gas is evaporated into after these electrolyte or macromolecular material are heated, therefore the pressure increase of capacitor casing 1 inside is made, and the capacitor element 2 of capacitor casing 1 inside and closing component 3 also because of the factor of enclosure interior pressure increase, and can produce the stress of distortion.
When capacitor element 2 temperature distortion, if be expressed to the inner surface of closing component 3, capacitor element will be made to produce distortional stress, the insulating barrier of capacitor element 2 or dielectric layer may be made to be destroyed, and cause the situation of current leakage to produce, closing component 3 also may because be subject to the extruding of capacitor element 2 on the other hand, and the sealing of itself and capacitor casing 1 is destroyed, and make aqueous vapor or other impurity enter in capacitor casing, cause the insulation of capacitor element 2 to be destroyed.
In known techniques, for avoiding the surface being expressed to closing component 3 during capacitor element 2 temperature distortion, usually make to keep a gap between capacitor element 2 and closing component 3.But capacitor element 2 easy generation in capacitor casing 1 will be made thus to rock, and cause capacitor element electrical characteristic to change, and have influence on the stability of the electrical characteristic such as electric current, impedance of capacitor.
In addition, when capacitor welding is on circuit substrate, capacitor is with the direction of one end of closing component 3 towards circuit substrate, the two-terminal 4 of capacitor is plugged on circuit substrate, and is connected with circuit substrate with the terminal 4 of scolding tin by capacitor.In the structure of the capacitor commonly used, the end face of closing component 3 is plane, therefore when terminal is inserted on circuit substrate, the end face of closing component 3 may directly be conflicted on the surface of circuit substrate, the problem that will produce thus includes: (1) is when capacitor welding, when capacitor casing 1 internal pressure raises because temperature rises, closing component 3 outwards can be extruded, make the end face of closing component 3 be expressed to circuit substrate, cause circuit substrate to be out of shape or the terminal of capacitor is destroyed; (2) end contact of closing component 3 is to the surface of circuit substrate, the space that the volatilization gas produced when capacitor terminal 4 will be made to weld with circuit substrate does not flow, scolding tin also may because the gap between the end face of closing component 3 and circuit substrate be too small simultaneously, produce capillarity, cause the unexpected flowing of scolding tin, and cause the defect that capacitor terminal 4 welds.
Due to above reason, cause the Winding-type solid electrolytic capacitor considerable defect in use commonly used, therefore, how by the improvement of structural design, reduce Winding-type solid electrolytic capacitor because welding temperature rises the harmful effect produced, overcome above-mentioned disappearance, become this cause one of important topic for solving.
