Abstract
The utility model discloses a capacitor which can effectively improve dielectric strength. The capacitor comprises electrolytic paper and cathode aluminium foil disposed on the electrolytic paper. Liner electrolytic paper is arranged between the electrolytic paper and the cathode aluminium foil and simultaneously a conducting needle is arranged on the cathode aluminium foil. In the production process of nail joint and winding, a layer of electrolytic paper is additionally arranged on an original electrolytic paper (barrier paper) at a nail joint position where the conducting needle and the aluminium foil are contacted, so that the dielectric strength of the capacitor is enhanced, thereby preventing the electrolytic paper from being stabbed and reducing the rate of adverse products caused by blast and breakdown. Besides, the number of times of customer complaint to products is reduced, the overall cost is effectively reduced and the capacitor is suitable for popularization.
Description
Technical field
The utility model relates to the high-voltage electrolysis capacitor technical field, the concrete capacitor that relates to a kind of effective raising dielectric strength.
Background technology
In the nail joint manufacturing process of the capacitor in existing the production, often use electrolytic paper (barrier paper), also can avoid the phenomenon of breakdown and explosion simultaneously to prevent positive and negative aluminium foil contact short circuit.But; Because of guide pin and aluminium foil position contacting meeting convexity; This boss and the burr that occurs because of nail joint all can be stabbed electrolytic paper, thereby make capacitor when aging, be easy to occur puncturing and situation such as blast, cause fraction defective higher; Especially terminal client is easy to generate quality hidden danger, is unfavorable for its safe and efficient and stable using.
The utility model content
The purpose of the utility model is to solve the problem that exists in the prior art, and the capacitor of effective raising dielectric strength of a kind of high pressure 350WV-500WV is provided.
The utility model is achieved through following technical scheme:
A kind of capacitor of effective raising dielectric strength comprises electrolytic paper and is located at the negative pole aluminium foil on the electrolytic paper.Between electrolytic paper and negative pole aluminium foil, be provided with the liner electrolytic paper; In addition, the negative pole aluminium foil is provided with guide pin.
The liner electrolytic paper is located at the outer surface of negative pole aluminium foil the superiors riveted joint position.
The riveted position of guide pin is positioned at the inner surface of negative pole aluminium foil the superiors riveted joint position, and extend outside the negative pole aluminium foil at all the other positions of guide pin simultaneously.
The length range of liner electrolytic paper is 70mm～90mm.
The usefulness of the utility model is:
The utility model in the nail joint position that guide pin contacts with aluminium foil, increases one deck electrolytic paper again on original electrolytic paper (barrier paper) basis when capacitor nail joint coiling processing procedure; The dielectric strength of capacitor is strengthened, prevented that electrolytic paper is wounded by stabbing, reduced because of blast and puncture the product fraction defective that causes; Simultaneously also reduced product by the number of times of customer complaint; Not only effectively save whole cost, also promoted quality of finished, but possessed preferable generalization.
Description of drawings
To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:
Fig. 1 is the structural representation of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Be illustrated in figure 1 as the capacitor of a kind of effective raising dielectric strength of the utility model preferred embodiment, comprise electrolytic paper 3 and be located at the negative pole aluminium foil 1 on the electrolytic paper 3.Between electrolytic paper 3 and negative pole aluminium foil 1, be provided with liner electrolytic paper 4; In addition, negative pole aluminium foil 1 is provided with guide pin 2.
Liner electrolytic paper 4 is located at the outer surface of negative pole aluminium foil 1 the superiors riveted joint position.
The riveted position of guide pin 2 is positioned at the inner surface of negative pole aluminium foil 1 the superiors riveted joint position, and extend outside the negative pole aluminium foil 1 at all the other positions of guide pin 2 simultaneously.
The length range of liner electrolytic paper 4 is 70mm～90mm.
In the production, liner electrolytic paper 4 is wound into a complete fuse with electrolytic paper 3, negative pole aluminium foil 1 and other corresponding assembly such as anodal aluminium foil.In practical application, the utility model can prevent effectively that electrolytic paper 3 is wounded by stabbing, thereby has avoided the puncture that capacitor occurs when aging easily and the phenomenon of blast.The utility model can effectively improve the dielectric strength of aluminum electrolytic capacitor through brief structure, reduces its risk of explosion and punctures fraction defective.
