Abstract
A novel structure preventing a capacitor from polar-shell belongs to the technical field of capacitors, and the structure comprises a case, a cover plate arranged on a top of the case, and a capacitor core arranged inside the case, a polarity terminal of the capacitor core is provided with leading wires, the capacitor core is wrapped outside by a contraction cannula, the contraction cannula is PET thermal contraction cannula, the contraction cannula is connected with an upper positioning sleeve, and filling agent is filled between the contraction cannula and the case. The novel structure preventing the capacitor from polar-shell is simple in structure and reasonable in design, the contraction cannula is used to replace existing lower positioning sleeve, the thermal contraction cannula sleeves the capacitor core welded with guide lines from a bottom, after heating process, the thermal contraction cannula contracts and wraps the capacitor core tightly, and even metal spraying dusts fall off from edges of a metal spraying layer of the capacitor core, the metal spraying dusts will be wrapped inside the thermal contraction cunnula, so polar-shell phenomenon will not happen.
Description
Technical field
The utility model relates to the capacitor technology field, relates in particular to a kind of new-type structure that prevents the capacitor pole shell.
Background technology
Electric capacity is called in the common letter of capacitor, represents with letter C.Definition 1: capacitor as its name suggests, is ' container of dress electricity ', is a kind of device that holds electric charge.English name: capacitor.Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in handing over every straight-through in the circuit, is coupled bypass, filtering, resonant tank, power conversion, the aspects such as control.
Say that in the market its internal structure of capacitor of selling is capacitor body, plug, gilding layer, positioning sleeve, lead-in wire, cover plate, aluminum hull and filler are assembled up and down.More than each parts to form the production technology of capacitor ripe already now, but prior art is because capacitor body has multi-layered enveloped film outward, and encapsulated membranes Width fuse is all lacked 2mm, be the short 1mm in every limit, consequent step is easily broken off gilding layer, and gilding layer very easily produces breaking releasing and causes utmost point shell at capacitor internal after vibrations repeatedly herein.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, reasonable in design, new-type structure that prevents the capacitor pole shell that cost is low, safe.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of new-type structure that prevents the capacitor pole shell, comprise housing, be arranged on the cover plate of case top and place the capacitor body of enclosure interior, polar end on the described capacitor body is provided with lead-in wire, described capacitor body is wrapped with shrink sleeve, be connected with positioning sleeve on the described shrink sleeve, be marked with filler between described shrink sleeve and the housing.
Described filler is epoxy resin.
Described shrink sleeve is the PET heat-shrinkable tube.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, replace existing lower positioning sleeve with shrink sleeve, thermal contraction casing tube is entangled the capacitor body that has welded wire from the bottom, again fuse is put into baking oven with the baking of 85 ± 5 ℃ baking oven after 20～30 minutes in the lump together with sleeve pipe, thermal contraction casing tube has shunk with the tight parcel of fuse, even if fuse gilding layer edge has the metal spraying ash to come off also be wrapped in by thermal contraction casing tube in, therefore utmost point shell phenomenon can not occur.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: the 1-housing; The 2-cover plate; The 3-capacitor body; The 4-lead-in wire; The 5-shrink sleeve; The upper positioning sleeve of 6-; The 7-filler.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of new-type structure that prevents the capacitor pole shell, comprise housing 1, be arranged on the cover plate 2 of case top and place the capacitor body 3 of enclosure interior, polar end on the capacitor body 3 is provided with lead-in wire 4, capacitor body 3 is wrapped with shrink sleeve 5, shrink sleeve 5 is the PET heat-shrinkable tube, be connected with positioning sleeve 6 on the shrink sleeve 5, be marked with filler 7 between shrink sleeve 5 and the housing 1, filler 7 is epoxy resin.The utility model replaces existing lower positioning sleeve with shrink sleeve 5, shrink sleeve 5 is entangled go between well 4 capacitor body 3 of welding from the bottom, again capacitor body 3 is put into baking oven with the baking of 85 ± 5 ℃ baking oven after 20～30 minutes in the lump together with shrink sleeve 5, thermal contraction casing tube 5 has shunk and with capacitor body 3 tight parcels, even if capacitor body 3 gilding layer edges have the metal spraying ash to come off also be wrapped in by thermal contraction casing tube 5 in, avoid occuring utmost point shell phenomenon.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
