Abstract
The utility model relates to a capacitor housing. The upper surface of the housing is provided with an opening, and an edge with a special uneven form is formed at the opening after the surface of the opening is processed by a die by injection molding. Through special process of the opening of the housing of the capacitor, capillarity is prevented, filled gum is not easy to flow out of the surface of the housing, the appearance neatness is enhanced, and simultaneously, the production efficiency is raised.
Description
Technical field
The utility model relates to a kind of capacitor case.
Background technology
Pour into the common practices of potting resin in the capacitor case as shown in Figure 1, concrete operations are as follows:
Encapsulating is to pour into a certain amount of potting resin in capacitor case body 1 for the first time, make it be evenly distributed on the capacitor case bottom, then capacitor body 3 is put into capacitor case body 1, next carry out the encapsulating second time, make potting resin fill whole capacitor other spaces except fuse 3, during common for the second time encapsulating, all need potting resin fills with till shell aperture 2 places, this moment is because capillarity, so that the resin that pours into for the second time can flow to the surface of shell, must in time wipe out; On the other hand, when the curing temperature adjustment of resin solidification operation not at that time, the viscosity of resin can reduce, this also can cause bad order so that the resin that pours into flows to the surface of shell, production efficiency reduces.
The utility model content
Technical problem to be solved in the utility model provides a kind of capacitor case, prevents that the potting resin that pours into from flowing to case surface.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of capacitor case, this capacitor case comprises outer cover body, form a shell aperture on the surface of described outer cover body, the edge of described shell aperture is through Mould Machining, behind the ejection formation, the edge with rough wavy structure of formation.
The beneficial effects of the utility model are: improve on the basis at existing capacitor case, lead to the shell opener place is processed, namely use Mould Machining, behind ejection formation, what form has a rough special shape edge, and this improvement prevents the generation of capillarity effectively, makes the natural gum that pours into be difficult to flow to the surface of shell, improve the tidiness of outward appearance, also improved production efficiency simultaneously.
Description of drawings
Fig. 1 is capacitor body encapsulation process schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model partial sectional view;
In the accompanying drawing, the list of parts of each label representative is as follows:
1, outer cover body, 2, shell aperture, 3, capacitor body
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Fig. 2 is the utility model structural representation, this capacitor case comprises outer cover body 1, forms a shell aperture 2 on the surface of described outer cover body 1, and the edge of described shell aperture 2 is through Mould Machining, behind the ejection formation, the edge with rough wavy structure of formation.
Encapsulation process below in conjunction with capacitor body 3 is further expalined.
At first carry out the encapsulating first time, in capacitor case body 1, pour into a certain amount of potting resin, make it be evenly distributed on the capacitor case bottom, then capacitor body 3 is put into capacitor case body 1, next carry out the encapsulating second time, make potting resin fill whole capacitor other spaces except fuse 3, potting resin fills with till shell aperture 2 places, because there is the edge of rough special shape at described capacitor case opening 2 places, the generation of capillarity in the time of effectively preventing encapsulating, thereby prevent that potting resin from flowing to outer cover body 1 surface, improved the tidiness of outward appearance, also improved production efficiency simultaneously.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
Claims (1)
1. a capacitor case is characterized in that, this capacitor case comprises outer cover body, form a shell aperture on the surface of described outer cover body, the edge of described shell aperture is through Mould Machining, behind the ejection formation, and the edge with rough wavy structure of formation.
