A kind of Anti-seismic ox horn aluminium electrolutic capacitor
Technical field
The present invention relates to a kind of aluminium electrolutic capacitor, the ox horn aluminium electrolutic capacitor of especially a kind of Anti-seismic.
Background technology
Ox horn aluminium electrolutic capacitor under the vibratory equipments such as sound equipment, automobile, operating mode equipment, passes through ox horn aluminium electroloysis
Capacitor terminal assembles on circuit boards, and aluminium shell of capacitor will not vibrate with vibration equipment, but ox horn aluminium electroloysis is electric
The fuse of container is connected with package terminal by conductive foil, and the fuse of ox horn aluminium electrolutic capacitor will be with the said equipment
Vibrating and vibrate, the conductive foil for causing fuse to be connected with package terminal is easily folding, cracks or is broken, so as to
Open loop state is formed, capacitor fails.
At present, the fixation for ox horn type aluminium electrolytic capacitor slugs generally borrows the making of bolt-type aluminum electrolytic capacitor
Method, fixed using gel or pitch encapsulation, but unlike bolt-type aluminum electrolytic capacitor, bolt type aluminium electrolytic capacitor
Device is explosion-proof provided with explosionproof hole progress on the cover board, and bolt-type aluminum electrolytic capacitor vertical can only be pacified when being installed in equipment
Dress, and ox horn aluminium electrolutic capacitor is a kind of handstand mounting means, works as ox generally by ox horn terminal insertion circuit board apertures
After irrigating gel or pitch inside aluminum corner brace polarized capacitor aluminum case, the explosion-proof performance of ox horn type aluminium electrolutic capacitor can be influenceed, and
And perfusion gel or pitch do not change fuse vibration with the said equipment vibration inside ox horn aluminium electrolutic capacitor.In addition, fill
The gel or pitch of note can increase the weight of fuse, so increase conductive foil and crackle or risk of breakage occur under vibration.
The U of patent CN 201893241 provide a kind of shock-proof type aluminium electrolutic capacitor of lead-foot-line, and the mode is to adopt
One aluminum hull set of increase outside aluminum hull is taken, takes ox horn aluminum electrolytic capacitor terminal to fix on circuit boards, the work that terminal rises
Role is covered with aluminum hull can be substituted completely.Therefore, the U patents of CN 201893241 can not solve aluminum hull inner core and shake
Dynamic, increase valve jacket is unfavorable for radiating outside capacitor in addition.
As can be seen here, ox horn type aluminium electrolutic capacitor does not solve antiknock quality also well at present.But ox horn type aluminium
Electrolytic capacitor is now widely used for various vibration environments, such as sound equipment, automobile engine, hay mover, cuts road machine etc., urgently
Need to provide a kind of well-set ox horn aluminium electrolutic capacitor.
The content of the invention
