Abstract
The utility model relates to a plastic casing capacitor with safety protective function. The utility model solves the problems of the unstable capacitor performance and the short service life of the existing plastic casing capacitor. The utility model is characterized in that a capacitor core body is loaded in a columnar aluminium casing, the aluminium casing is loaded in a plastic casing and epoxy resin is injected into the aluminium casing and the plastic casing. The utility model prolongs the service life of the plastic casing capacitor with safety function, and reduces the manufacturing cost.
Description
Technical field
The utility model relates to and has safety function plastic casing capacitor.
Background technology
Traditional function of safety protection plastic casing capacitor that has all adopts metal metallized safety film made, the epoxy resin embedding.This structural safety protection principle is: after puncturing appearred in certain point, the safeties that connect around the single grid were blown under the effect of electric current, thereby make the breakdown area be in off-position, play the safeguard protection effect.Even puncturing appears in the zone that its shortcoming is very little, also can cause the loss of whole unit grid contents amount, so capacitance loss is bigger in this constructed products use, useful life, more non-metallic safety film product was low.This infrastructure product belongs to the semitight state simultaneously, and very easily the moisture absorption causes the variation of properties of product.The present complete dependence on import of safety diaphragm that uses, manufacturing cost is higher.
Summary of the invention
The purpose of this utility model is: provide a kind of new construction to have safety function plastic casing capacitor.
The structural design scheme of realizing the foregoing invention purpose is such:
1, the novel plastic case capacitance device that has function of safety protection, comprise core body, last positioning sleeve, following positioning sleeve, draw copper core, bursting diaphragm, conductive pole, insulator and iron covering, it is characterized in that: described core body sealing is located in the column aluminium mass shell body, and column aluminium mass shell body top is provided with protecting cover; Described column aluminium mass shell body is located in the column plastic casing, and column plastic casing top is provided with seal cover, is provided with epoxy resin between aluminium mass shell body and the plastic casing, and two extraction poles extend outside the plastic casing.
2, according to above-mentioned 1 described novel plastic case capacitance device with function of safety protection, it is characterized in that: described protecting cover is the metal protecting cover, or is plastic cover.
The utility model is packed core body in the column attitude aluminium mass shell body, when puncturing appears in a certain zonule, can not cause the loss of whole unit grid contents amount; Top at aluminium mass shell body installs protecting cover additional, to guarantee behind the product failure certain stretching space being arranged; Because core body adopts the hermetically sealed installation of aluminium mass shell body, has humidity resistance preferably, guarantee that properties of product are stable.
The utility model has improved and has had safety function plastic casing capacitor useful life, has reduced manufacturing cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
As seen from Figure 1, have the novel plastic case capacitance device of function of safety protection, comprise core body 1, last positioning sleeve 2, following positioning sleeve 3, draw copper core 4, bursting diaphragm 5, conductive pole 6, insulator 7 and iron covering 8; Core body 1 is seal-installed in the column aluminium mass shell body 9, and column aluminium mass shell body 9 tops are equipped with protecting cover 10; Column aluminium mass shell body 9 is installed in the column plastic casing 11, and sealing protecting cover 14 is equipped with at column plastic casing 11 tops, and 12, two extraction poles 13 of infusion epoxy resin extend outside the plastic casing 11 between aluminium mass shell body 9 and the plastic casing 11.
Sealing protecting cover 14 can be the metal protecting cover, also can be plastic cover.
Claims (2)
