Abstract
The utility model relates to the field of capacitor structures and manufacture technology, in particular to a cover body of a capacitor packaged by epoxy resin. The cover body comprises a top cover plate and a combined part arranged at the edge of the lower end surface of the top cover plate; a hole for extracting a cable is penetrated on the top cover plate or an extracting terminal is arranged on the top cover plate; and the cover body is characterized in that an exhaust hole for filling is arranged on the top cover plate. The cover body mainly solves the technical problems that when in filling and sealing of epoxy resin for the existing products, the exhaust of air is unsmooth and the epoxy resin is difficult to fill up, thereby being conductive to simplify the operation of filling and sealing and improving the product performance.
Description
Technical field
The utility model relates to the lid in capacitor arrangement and manufacturing technology field, particularly a kind of epoxy resin encapsulation capacitor.
Background technology
Existing epoxy resin encapsulation capacitor can be divided into from a structural point lid and two kinds of uncovereds, wherein: cover the formula epoxy resin encapsulation capacitor by being divided into two kinds of cable extraction and terminal formulas.
The formula epoxy resin encapsulation capacitor is covered in having that described cable is drawn: it comprises a shell and can be covered in the lid of shell aperture end that this lid is provided with the location hole that is used to locate the outgoing cable line; Outgoing cable line hole and capacitor body that a ccontaining capacitor body in this shell, the lower end of an outgoing cable line pass on the lid are realized being welded to connect, and then carry out the encapsulation location of capacitor body by can epoxy resin in shell.
The formula epoxy resin encapsulation capacitor is covered in having that described terminal is drawn: it comprises a shell and can be covered in the lid of shell aperture end that this lid is provided with the terminal that is used to peg graft; A ccontaining capacitor body in this shell, the lower end of terminal and capacitor body are realized being welded to connect, and then carry out the encapsulation location of capacitor body by can epoxy resin in shell.
Said structure is difficult to accomplish epoxy resin is filled up when canned epoxy resin, when reason is the potting operation, earlier can not be with on the cover cap, epoxy resin must be poured into behind the shell again with on the cover cap, and itself also have a certain space in the lid, the space in the lid just is not easy the filling epoxy resin material, caused the capacitor assembling after, inside still has certain air can't discharge, and has influence on the performance of product.
The utility model content
The purpose of this utility model is to provide a kind of lid of epoxy resin encapsulation capacitor, mainly solve existing product when potting epoxy resin, air is discharged smooth and is not easy technical problem that epoxy resin is filled up, and it helps simplifying the potting operation, improves the performance of product.
For achieving the above object, the technical solution of the utility model is:
A kind of lid of epoxy resin encapsulation capacitor, it comprises lamina tecti and is arranged at the joint portion at edge, lamina tecti lower surface; Be equipped with outgoing cable line hole on this lamina tecti or leading-out terminal is set; It is characterized in that: this lamina tecti is provided with canned steam vent.
The lid of described epoxy resin encapsulation capacitor is characterized in that: this canned steam vent is more than 2 or 2.
The lid of described epoxy resin encapsulation capacitor is characterized in that: be provided with slider between the leading-out terminal on this cover plate.
By said structure, the utility model mainly has following advantage:
1, operates again after use the utility model lid can cover lid with operating in of potting epoxy resin.
2, the utility model is provided with canned steam vent, when carrying out the operation of potting epoxy resin, both can be used as and has poured into the hole, can be used as the air tap again, help like this space in the capacitor is filled up, and help air-out more up hill and dale, improved the quality of product.

Embodiment
See also Fig. 1,2, they are structural representations of the utility model embodiment 1.It is cable draw the cover body structure that covers the formula epoxy resin encapsulation capacitor arranged.As shown in the figure: it comprises lamina tecti 1 and is arranged at the joint portion 2 at edge, lamina tecti 1 lower surface that this joint portion 2 can be attached to the joint portion of upper end in the capacitor case.Be equipped with outgoing cable line hole 3 on this lamina tecti 1, this lamina tecti 1 is provided with canned steam vent 4.When only having a canned steam vent 4 on the lamina tecti 1, during potting epoxy resin, this hole should be used to pour into epoxide resin material, is used for air in discharging shell again.Therefore, if canned steam vent 4 is set to more than 2 or 2, then product structure is more reasonable.
See also Fig. 3,4 again, they are structural representations of the utility model embodiment 2.It is terminal draw the cover body structure that covers the formula epoxy resin encapsulation capacitor arranged.As shown in the figure: it comprises lamina tecti 1 and is arranged at the joint portion 2 at edge, lamina tecti 1 lower surface, this joint portion 2 can be attached to the joint portion of upper end in the capacitor case, as: can be provided with on this joint portion in conjunction with screw thread 21, with cooperate upper end in the shell in conjunction with screw thread.On this lamina tecti 1 leading-out terminal 5 is set, this lamina tecti 1 is provided with canned steam vent 4.When only having a canned steam vent 4 on the lamina tecti 1, during the potting epoxy, this hole should be used to pour into epoxide resin material, is used for air in discharging shell again.Therefore, if canned steam vent 4 is set to more than 2 or 2, then product structure is more reasonable.
In addition, a slider 6 is set, to play the insulation buffer action between the leading-out terminal 5 on this cover plate.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
