Abstract

The utility model discloses a novel capacitor, which comprises an aluminum shell (1), an insulation sleeve (2), a core body (3) and an electrode (4), wherein the insulation sleeve (2) and the core body (3) are arranged in an accommodation cavity inside the aluminum shell and the insulation sleeve (2) is sleeved outside the core body (3); the electrode (4) is arranged on the aluminum shell (1) and is electrically connected with the core body (3) through a welding point (5); and a plurality of first dents (61) are formed on the aluminum shell (1) through pressing to maintain close contact between the insulation sleeve (2) and the core body (3) in the radial direction. In the utility model, the plurality of first dents (61) are formed on the aluminum shell (1) through pressing so that the aluminum shell can press the insulation sleeve tightly, and the insulation sleeve is wrapped outside the core body so that the core body can be prevented from rocking, the possibility of sealing-off between the core body and the electrode can be avoided, and the working stability and reliability of the capacitor can be improved.

Description

A kind of novel capacitor

Technical field

The utility model relates to a kind of electronic component, is specifically related to a kind of novel capacitor.

Background technology

Capacitor abbreviates electric capacity usually as, is one of a large amount of electronic components that use in the electronic equipment, is widely used in the separated aspects such as friendship, coupling, bypass, filtering, resonant tank, power conversion, control that lead directly to of circuit.As shown in Figure 1, be the structural representation of a kind of capacitor in the prior art.With reference to Fig. 1; This capacitor comprises aluminum hull 1, insulating case 2, core body 3, electrode 4, and wherein, insulating case 2, core body 3 are arranged in the ccontaining cavity of aluminum hull 1 inside; And insulating case 2 is set in core body 3 outsides, and electrode 4 is arranged on the aluminum hull 1 and with core body 3 and is electrically connected through pad 5.Above-mentioned capacitor is in operational environment, and core body 3 rocks in the inner ccontaining cavity of aluminum hull easily, thereby causes the core body 3 and the pad 5 of electrode 4 risk of sealing-off to occur, influences the job stability and the reliability of capacitor.

The utility model content

To the problem that prior art exists, the purpose of the utility model is to propose a kind of novel capacitor, can prevent that core body from rocking, and has avoided occurring between core body and the electrode possibility of sealing-off, has improved the stability and the reliability of capacitor work.

For reaching this purpose, the utility model adopts following technical scheme:

A kind of novel capacitor; Comprise aluminum hull, insulating case, core body, electrode; Wherein, insulating case, core body are arranged in the inner ccontaining cavity of aluminum hull, and insulating case is set in the core body outside; Electrode is arranged on the aluminum hull and with core body and is electrically connected through pad, and compacting formation multiple tracks first indenture is radially closely contacting with core body to keep insulating case on aluminum hull.

Preferably, on insulating case, form multiple tracks second indenture, and second indenture is corresponding with the position of first indenture.

Preferably, said first indenture axial arranged along aluminum hull.

Based on disclosing of above technical scheme, the utlity model has following beneficial effect:

In a kind of novel capacitor that the utility model proposes; Form the multiple tracks indenture through compacting on aluminum hull; Make aluminum hull push down insulating case tightly, insulating case is coated on outside the core body, can prevent that core body from rocking; Avoid occurring between core body and the electrode possibility of sealing-off, improved the stability and the reliability of capacitor work.
