Abstract
The utility model relates to a novel aluminium electrolytic capacitor. The aluminium electrolytic capacitor comprises a foil guiding bar and a negative foil riveted with each other, wherein a section of gasket aluminium foil piece is covered and riveted at the part of the negative foil riveted with the foil guiding bar; the foil guiding bar is positioned between the negative foil and the gasket aluminium foil piece; the width Wi of the gasket aluminium foil piece is smaller than, equal to or larger than the width W of the negative foil; and both the left edge and the right edge of the gasket aluminium foil piece can be freely adjusted relative to the lengths (L1 and L2) of the left edge and the right edge of the foil guiding bar respectively according to the winding requirement. By adopting the novel structure, a new current path is added, so that the internal resistance of the capacitor is effectively reduced, the ripple resistance of the capacitor is improved, the service life of the capacitor is prolonged, meanwhile, burrs generated during cold welding and riveting of the negative foil and the foil guiding bar are effectively avoided, and short circuits and discharge of burr tips in the electric field are weakened.
Description
[technical field]
The present invention relates to a kind of novel aluminum electrochemical capacitor.
[background technology]
Along with electron trade makes constant progress, the client is more and more higher to the anti-ripple ability of alminium electrolytic condenser, the production technology of existing alminium electrolytic condenser adopts traditional method for designing, cause the internal resistance of product big, be unfavorable for the heat conduction and the heat radiation of alminium electrolytic condenser fuse inside, it is not very desirable improving anti-ripple ability simultaneously, and cost is higher; And when negative pole is led chaff cold welding riveted, be easy to generate burr and cause the electric capacity puncture short.
[utility model content]
The utility model provides the internal resistance of a kind of minimizing product, increases the anti-ripple ability of product, prolongs life of product, produces the novel aluminum electrochemical capacitor of burr when effectively avoiding leading chaff cold welding riveted.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of novel aluminum electrochemical capacitor comprises and leads chaff and riveted has the anode foil of leading chaff, has the anode foil place that leads chaff also to cover riveted at riveted one segment liner aluminium foil is arranged; The described chaff of leading is between anode foil and liner aluminium foil.
Aforesaid a kind of novel aluminum electrochemical capacitor, the width W i of described liner aluminium foil less than, be equal to or greater than the width W of anode foil.
Aforesaid a kind of novel aluminum electrochemical capacitor, the left hand edge of described liner aluminium foil can freely be adjusted as required with respect to the length L 1 of leading the chaff left hand edge.
Aforesaid a kind of novel aluminum electrochemical capacitor, the right hand edge of described liner aluminium foil can freely be adjusted as required with respect to the length L 2 of leading the chaff right hand edge.
Aforesaid a kind of novel aluminum electrochemical capacitor, the left hand edge of described liner aluminium foil and right hand edge can freely be adjusted as required with respect to the left hand edge of leading chaff and right hand edge length L 1, L2 respectively.
Aforesaid a kind of novel aluminum electrochemical capacitor, described liner aluminium foil cover fully that riveted has the zone of leading chaff on the anode foil.
Aforesaid a kind of novel aluminum electrochemical capacitor, described liner aluminium foil is pressed in leads above the chaff, and together riveted on anode foil.
Advantage of the present utility model:
Of the present utility model when leading chaff and anode foil riveted, lead chaff by a segment liner aluminium foil from the another side covering of leading chaff, and with the anode foil riveted, make and lead chaff between anode foil and liner aluminium foil, this structure, increased new current path, can effectively reduce the product internal resistance, improve the anti-ripple ability of product, prolonged product useful life, the burr that produces in the time of can effectively avoiding simultaneously anode foil and lead chaff cold welding riveted has weakened the short circuit dischange at burr tip under electric field.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
Shown in Fig. 1, present embodiment provides a kind of novel aluminum electrochemical capacitor, comprise and lead chaff 1 and riveted has the anode foil 2 of leading chaff 1, there are anode foil 2 places that lead chaff 1 also to cover riveted at riveted one section liner aluminium foil 3 of leading chaff 1 is arranged, wherein, liner aluminium foil 3 covers fully that riveted has the zone of leading chaff 1 on the anode foil 2, and the described chaff 1 of leading is between anode foil 2 and liner aluminium foil 3; The width W i of described liner aluminium foil 3 is less than the width W of anode foil 2; The left hand edge of described liner aluminium foil 3 and right hand edge can freely be adjusted according to the coiling needs with respect to the left hand edge of leading chaff 1 and right hand edge length L 1, L2 respectively.Certainly, according to the assembling needs, the width W i of described liner aluminium foil 3 also can be more than or equal to the width W of anode foil 2.
Adopt structure of the present utility model, increased new current path, improved the anti-ripple current ability of product, weakened the discharge of under electric field, leading burr tip, chaff riveted place, improved reliability of products, prolonged the useful life of product.
Aluminium electrolytic capacitor of the present utility model, during making, earlier as required, adjust the installation site of liner aluminium foil 3, then liner aluminium foil 3 is pressed in lead above the chaff 1 and together riveted on anode foil 2, again electrolytic paper is layered on the anode foil 2, begin to reel from anode foil 2 then, seal in a band bottom tube shape aluminum hull with rubber stopper after spooling impregnation, promptly finish this New Type Aluminum Electrolytic Capacitor processing and fabricating.
Aluminium electrolytic capacitor of the present utility model can also have other distortion, also can apply in the processing and fabricating of cathode foil as this structure; In a word, do conspicuous change, and other every change that does not break away from patent essence of the present invention all should be included within the described scope of claim according to the prompting of above-mentioned example.
