Abstract

The utility model relates to a long-service-life capacitor, comprising an aluminum shell, a wiring terminal and a metallized film; an outgoing line of the metallized film and the wiring terminal are connected together; the capacitor also comprises an insulation sealing part with an inversed I shape; the insulation sealing part is arranged at the side surface of the aluminum shell; and the wiring terminal penetrates through the insulation sealing part. According to the long-service life capacitor, the interior and the exterior of the aluminum shell of the capacitor are isolated by the inversely placed I-shaped insulation sealing part, and the insulation sealing part is placed at the side surface, less influenced by vapor and dust, of the aluminum shell, so the aging degree of the capacitor is effectively controlled, the service life of the capacitor is prolonged, and the implementation effect is good.

Description

A kind of long-life capacitor

Technical field

The utility model relates to a kind of capacitor, and especially a kind of long-life capacitor, belongs to technical field of electronic components.

Background technology

Existing capacitor be metallized film is rolled after, be arranged in aluminum hull, on aluminum hull, be provided with binding post, binding post is connected with metallized film exit, then seals pour into certain epoxy resin or vegetable oil in aluminum hull housing after.Because binding post is arranged on aluminum hull end face, binding post is provided with seal through aluminum hull position, and the seal on end face, under the impact of steam, dust etc., is easy to aging, cause capacitor internal epoxy resin or vegetable oil generation seepage, affect the useful life of capacitor.

Utility model content

The deficiency that the utility model exists for prior art just, provides a kind of long-life capacitor.

For addressing the above problem, technical solution adopted in the utility model is as follows:

A kind of long-life capacitor, comprise aluminum hull, binding post and metallized film, lead-out wire and the binding post of metallized film link together, described capacitor also comprises insulating sealer, insulating sealer is " work " font of putting upside down, insulating sealer arranges on the side of aluminum hull, and binding post is through insulating sealer.

Compared with prior art, implementation result of the present utility model is as follows for the utility model:

Long-life capacitor described in the utility model, by " work " font insulating sealer of putting upside down, aluminium shell of capacitor inside and outside is isolated and sealed, and being placed on insulating sealer affected on less aluminum hull side by steam, dust, effectively control the degree of aging of capacitor, improved capacitor useful life, implementation result is good.

Accompanying drawing explanation

Fig. 1 is existing capacitor arrangement schematic diagram;

Fig. 2 is capacitor arrangement schematic diagram described in the utility model.

Embodiment

Content of the present utility model is described below in conjunction with specific embodiments.

As shown in Figure 1, be existing capacitor arrangement schematic diagram.Existing capacitor comprises aluminum hull 10 and binding post 11, and binding post 11 is arranged on the end face of aluminum hull 10.By binding post 11, capacitor is accessed in external circuit.

As shown in Figure 2, be capacitor arrangement schematic diagram described in the utility model.Capacitor described in the utility model comprises aluminum hull 10, binding post 11 and metallized film 12, and the lead-out wire of metallized film 12 and binding post 11 link together, and binding post 11 is arranged on the side of aluminum hull 10.Binding post 11 passes aluminum hull 10, and accesses external circuit.

Through aluminum hull 10 positions, be also provided with insulating sealer 13 at binding post 11 on aluminum hull 10, insulating sealer 13 " work " font for putting upside down, isolates the internal atmosphere of aluminum hull 10 and space outerpace seal.Binding post 11 passes insulating sealer 13, and accesses external circuit.

For aluminum hull 10, because inner side and outside have corresponding insulating sealer 13 to exist, be equivalent to be provided with two seals, therefore, epoxy resin or the vegetable oil of aluminum hull 10 inner perfusions can not leak.Similarly, in the time that outside steam, dust are larger, also cannot enter aluminum hull 10 inside by insulating sealer 13.Like this, guarantee the reliability of capacitor, extended its useful life.

Claims

1. a long-life capacitor, comprise aluminum hull (10), binding post (11) and metallized film (12), the lead-out wire of metallized film (12) and binding post (11) link together, it is characterized in that, described capacitor also comprises insulating sealer (13), insulating sealer (13) " work " font for putting upside down, insulating sealer (13) arranges on the side of aluminum hull (10), and binding post (11) is through insulating sealer (13).
