Abstract
The invention discloses a capacitor shell with a flanging, wherein a cavity of the capacitor shell is covered with a base film, the edge of the capacitor shell is outwards folded to form a curled edge, the base film extends to the curled edge from the cavity of the capacitor shell and covers the whole curled edge, after the flanging treatment is carried out on the capacitor shell, the base film completely covers the whole curled edge, the edge part is not contacted with an electrolytic medium any more, the electrolytic medium is prevented from permeating between the base film and the capacitor shell, the film peeling or falling is prevented, and the service life of a capacitor is greatly prolonged.
Description
Technical Field
The invention relates to the field of packaging shells, in particular to a capacitor shell with a flanging.
Background
When the capacitor shell is punched in the prior art, the edge part is not sealed, so that an electrolytic medium corrodes the joint of the film layer and the aluminum shell in the use process, the film can be removed after a long time, and the capacitor cannot be used after being damaged.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the above-mentioned problems in the related art. Therefore, the invention provides a capacitor shell with a flanging.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a take turn-ups's capacitor case, the inner chamber of capacitor case covers there is the base film, the edge of capacitor case is turned over outwards and is formed the turn-up, the base film follow the inner chamber of capacitor case extends to and covers whole turn-up on the turn-up.
As an improvement of the above technical solution, the curl abuts against an outer surface of the capacitor case, and the base film covered on the curl is spaced apart from an abutting position of the capacitor and the curl.
As a further improvement of the technical scheme, the height of the curled edge is set to be 0.8 mm.
Furthermore, the bottom of the outer surface of the capacitor shell is provided with a round angle, and the bottom of the inner cavity of the capacitor shell is provided with a round angle.
Further, the capacitor case comprises an aluminum material.
The invention has the beneficial effects that: the utility model provides a take turn-ups's capacitor shell, the inner chamber of capacitor shell covers there is the base film, the edge of capacitor shell is rolled over outwards and is formed the turn-up, the base film is followed the inner chamber of capacitor shell extends to the turn-up is gone up and is covered whole turn-up, carries out the turn-ups to the capacitor shell and handles the back, makes the base film cover whole turn-up completely, and the marginal portion no longer contacts with electrolytic medium, prevents that electrolytic medium from permeating between base film and the capacitor shell, realizes guaranteeing that the membrane can not take place to rise the layer or drop, has improved the capacitor life-span greatly.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic view of the mounting structure of the present invention.
Detailed Description
Referring to fig. 1, in the flanged capacitor case of the present invention, an inner cavity 2 of the capacitor case 1 is covered with a base film 3, an edge of the capacitor case 1 is folded outwards to form a flange 4, and the base film 3 extends from the inner cavity 2 of the capacitor case 1 to the flange 4 and covers the whole flange 4.
In practical use, after flanging treatment is carried out on the capacitor shell 1, the base film 3 completely covers the whole turned edge 4, the edge part is not contacted with an electrolytic medium any more, the electrolytic medium is prevented from permeating between the base film 3 and the capacitor shell 1, the film peeling or falling is avoided, and the service life of the capacitor is greatly prolonged.
As an improvement of the above technical solution, the curl 4 abuts against an outer surface of the capacitor case 1, and the base film 3 covered on the curl 4 is spaced apart from an abutting position of the capacitor and the curl 4.
The curling 4 is abutted against the outer surface of the capacitor shell, the base film 3 is spaced between the curling 4 and the outer surface of the capacitor shell, the covered edge of the base film 3 and the curling 4 is effectively concealed, and when the base film 3 is separated from the curling 4 due to the permeation of an electrolytic medium between the base film 3 and the curling 4, the abutting between the curling 4 and the capacitor shell is utilized to effectively prevent the peeling area of the base film 3 from expanding.
As a further improvement of the above technical solution, the height of the bead 4 is set to 0.8 mm.
Further, the bottom of the outer surface of the capacitor shell 1 is provided with a fillet, and the bottom of the inner cavity 2 of the capacitor shell 1 is provided with a fillet. The acute angle of the outer surface is set to be a round angle, so that a user is prevented from being scratched in use. And the acute angle at the bottom of the inner cavity 2 is set to be a round angle, which is beneficial to better covering the base film 3.
Further, the capacitor case 1 includes an aluminum material. Making the overall product lighter in weight.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
