Abstract
The invention relates to a core positioning sleeve for a capacitor. The core positioning sleeve comprises a positioning sleeve body of which the upper end is open and the lower end is enclosed or semi-enclosed; the core positioning sleeve is characterized in that a plurality of core positioning bulges are arranged at the inner bottom surface of the positioning sleeve body; and a filling space for a filler is formed among the core positioning bulges. According to the core positioning sleeve for the capacitor, the technical problem that an existing core positioning sleeve for the capacitor cannot ensure that the filler is filled between the bottom part of the capacitor core and the inner bottom surface of the core positioning sleeve is mainly solved, the bottom part of the capacitor core can be encapsulated by epoxy resin and the like, the reliability of a product is improved and the service lifetime of the product is prolonged.
Description
Technical field
The present invention relates to capacitor, particularly a kind of capacitor fuse positioning sleeve.
Background technology
In the manufacturing process of epoxy resin encapsulation capacitor, in order to solve the Insulation Problems between capacitor body and metal shell, main employing fuse positioning sleeve.Existing fuse locating sleeve structure is as shown in Figure 1, it is the cylindrical body of a upper end open lower end closed, its external diameter guarantees that fuse positioning sleeve can put into capacitor casing, internal diameter size for fuse positioning sleeve, capacitor body can be inserted and pour into the implants such as epoxy resin between capacitor body and fuse positioning sleeve inwall to require its internal diameter to guarantee, to realize the location of capacitor body.
In the use of above-mentioned prior art, it has been found that following problem:
After putting into fuse positioning sleeve due to capacitor body, bottom it be completely and fuse positioning sleeve inner bottom surface fully in contact with, although the support that capacitor body is comparatively consolidated can be made, but but cannot fill implants such as setting epoxy resin between the bottom of capacitor body and fuse positioning sleeve inner bottom surface, capacitor body fails to be encapsulated by implant entirety such as epoxy resin, therefore, the reliability causing product reduces, service life shortens.
Summary of the invention
It is an object of the invention to provide a kind of capacitor fuse positioning sleeve, mainly solve existing capacitor core locating sleeve cannot guarantee between the bottom of capacitor body and fuse positioning sleeve inner bottom surface, to fill the technical problem setting implant, the present invention can realize capacitor body and position in fuse positioning sleeve, and guarantee also to be encapsulated by implants such as epoxy resin bottom capacitor body, improve the reliability of product, extend the service life of product.
For achieving the above object, the present invention is realized in.
A kind of capacitor fuse positioning sleeve, it includes a upper end open, lower end closed or semi-enclosed positioning sleeve body；It is characterized in that: this positioning sleeve body inner bottom surface is provided with some fuse positioning convex, forms the packing space of implant between each fuse positioning convex.
Described capacitor fuse positioning sleeve, it is characterised in that: this positioning sleeve outer body is distributed some axially extended grooves.
Described capacitor fuse positioning sleeve, it is characterised in that: this positioning sleeve body bottom portion is provided with through hole.
Described capacitor fuse positioning sleeve, it is characterised in that: this positioning sleeve body outer bottom is provided with some reinforcements.
Described capacitor fuse positioning sleeve, it is characterised in that: this positioning sleeve body outer bottom is provided with some reinforcements, and these reinforcements are the distribution in divergent shape around through hole.
Above structure, the present invention has technique effect superior as follows.
Using and present invention can ensure that bottom capacitor body and have the packing space of implant between positioning sleeve body inner bottom surface, implant just can enter in the packing space forming implant between each fuse positioning convex 1, to guarantee the overall encapsulating to capacitor body.Through testing inspection, adopting the product of the present embodiment fuse positioning sleeve compared with tradition fuse positioning sleeve product, its reliability and service life all have a distinct increment.

Detailed description of the invention
Refer to Fig. 2,3, it is the structural representation of the present invention a kind of capacitor fuse positioning sleeve embodiment 1.As shown in the figure: it includes a upper end open, lower end closed or semi-enclosed positioning sleeve body；It is characterized in that: this positioning sleeve body inner bottom surface is provided with some fuse positioning convex 1, forms the packing space of implant between each fuse positioning convex 1.
During use, capacitor body is inserted positioning sleeve, and this is internal, owing to being supported by some fuse positioning convex 1 bottom capacitor body, thus it is ensured that bottom capacitor body and also there is between positioning sleeve body inner bottom surface the packing space of implant.Now, the implant such as encapsulated epoxy resin between capacitor body and fuse positioning sleeve, these implants just can enter in the packing space forming implant between each fuse positioning convex 1, to guarantee the overall encapsulating to capacitor body.Through testing inspection, adopting the product of the present embodiment fuse positioning sleeve compared with tradition fuse positioning sleeve product, its reliability and service life all have a distinct increment.
Refer to again Fig. 4,5, it is the structural representation of the embodiment of the present invention 2.Except the feature and advantage having described in embodiment 1.It also has following additional technical feature:
(1) this positioning sleeve outer body is distributed some axially extended grooves 2, and when fuse positioning sleeve is put in capacitor casing, the air in housing can pass through groove 2 and discharge, it is easy to install fuse positioning sleeve.It addition, when the implants such as epoxy resin are filled into position between fuse positioning sleeve and housing, may further ensure that air is discharged after inserting implant in this groove 2.
(2) this positioning sleeve body bottom portion is provided with through hole 4, and this through hole 4 is for extraction cable.
(3) this positioning sleeve body outer bottom is provided with some reinforcements 3, and these reinforcements 3 are not only able to strengthen the intensity of positioning sleeve body bottom portion, and the implants such as epoxy resin can also be filled into the gap between reinforcement 3, improve the reliability of product.As the preferred structure of one, this positioning sleeve body outer bottom is provided with some reinforcements 3, and these reinforcements 3 are the distribution in divergent shape around through hole 4.
It is only presently preferred embodiments of the present invention in sum, is not used for limiting the practical range of the present invention.Namely all equivalences made according to the content of the present patent application the scope of the claims change and modify, and all should be the technology category of the present invention.
