Description
Technical field
The utility model is related to capacitance technology field more particularly to a kind of electrolytic capacitors.
Background technology
Existing common aluminium electrolutic capacitor generally comprises guide pin, anode foils, Cathode Foil and electrolytic paper, and guide pin is riveted on phase
In the anode foils or Cathode Foil answered, electrolytic paper is located between anode foils and Cathode Foil.In existing processing, due to guide pin with
It is to be riveted simultaneously using shock wave between anode foils, Cathode Foil, burr is generated when this mode is easily when piercing riveting because magic flower, when
When anode foils, Cathode Foil wind to form core packet together with electrolytic paper, the burr can pierce through electrolytic paper, common aluminium electrolutic capacitor
Spark phenomenon can be generated in the state of using or being powered, be easy to cause short circuit, explosion of common aluminium electrolutic capacitor etc..Together
When, the riveting of existing aluminium tongue and winding core is susceptible to slight crack, influences the quality of capacitor.
Invention content
For the above problem of the prior art, the utility model provides a kind of electrolytic capacitor, which solves existing
Existing for some capacitances：Occurs the problem of burr and slight crack when aluminium tongue and aluminium foil riveting.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：
A kind of electrolytic capacitor, including two guide pins, aluminium foil and electrolytic paper, the guide pin includes needle body, stalk portion and aluminium tongue,
The aluminium tongue portion of guide pin and aluminium foil nail joint；
Further, multiple riveted holes are offered on the aluminium tongue and aluminium foil, the aluminium tongue and aluminium foil pass through multiple rivetings
The cooperation for connecing hole is riveted, wherein, the sum of aperture of multiple riveted holes is more than the half of aluminium tongue width on the aluminium tongue.
Further, the aperture all same of the aluminium tongue and the riveted holes on aluminium foil.
Further, the riveted holes on the aluminium tongue are arranged along the center line direction in stalk portion.
Further, the spacing of the riveted holes is identical.
Further, the riveting face of the aluminium tongue and aluminium foil nail joint is rectangle, and the both sides in the riveting face use curved circular
It slips over and crosses.
Further, the shape of the riveted holes is rectangular or round.
A kind of electrolytic capacitor of the utility model, has the advantages that：
The aluminium tongue of the utility model electrolytic capacitor, in riveting, can reduce burr generation and aluminium tongue and aluminium foil with aluminium foil
Occur slight crack the phenomenon that, to reduce product fraction defective, further improve product quality, have very big improvement result, can be big
It is big to reduce scrapping for product, improve finished product rate.

Embodiment 1
The present embodiment provides a kind of electrolytic capacitors, see Fig. 1 to Fig. 2, and the utility model electrolytic capacitor includes：Guide pin 1,
Aluminium foil 2, electrolytic paper 3, the guide pin 1 include needle body 4, stalk portion 5 and aluminium tongue 6, the aluminium tongue 6 and 2 nail joint of aluminium foil, aluminium tongue 6 and aluminium
Multiple riveted holes 7 are offered on foil 2, riveted holes 7 are made in advance, so will not generate burr during riveting, can be protected
Electrolytic paper improves the safety of product.
The aluminium tongue 6 and aluminium foil 2 are riveted by the cooperation of multiple riveted holes, multiple riveted holes on the aluminium tongue 6
The sum of aperture is more than the half of aluminium tongue width, and this design can reduce the spacing between riveted holes 7, prevent aluminium tongue 6 and aluminium foil 2
Occur slight crack during riveting, while can also further be reduced by extending the length of aluminium tongue 6 and reducing the aperture of riveted holes 7
There is the probability of slight crack.
The aperture all same of riveted holes 7 on the aluminium tongue 6 and aluminium foil 2.
Multiple riveted holes 7 on the aluminium tongue 6 are arranged along the center line direction in stalk portion 5.
The aluminium tongue 6 is identical with the spacing of riveted holes 7 on aluminium foil 2, and direct disposal molding, energy can be set by mold
Enough adjustment positioning reduced when subsequently riveting, greatly improve production efficiency.
The riveting face of the aluminium tongue 6 and 2 nail joint of aluminium foil is rectangle, and the both sides in the riveting face use arc rounding off,
