Abstract
The invention discloses a plastic cover plate of a capacitor. The plastic cover plate of the capacitor comprises a cover body, wherein an annular lower edge is arranged on the cover body, and the outer diameter of the annular lower edge gradually increases from bottom to top. The plastic cover plate of the capacitor further comprises reinforcing ribs, wherein the reinforcing ribs are arranged on the bottom face of the cover body, the number of the reinforcing ribs is more than one, and the reinforcing ribs are arranged in the radius direction of the cover body, and are independent from one another in the center of the cover body. According to the plastic cover plate of the capacitor, the strength of the cover plate of the capacitor can be improved, combination among an outer shell of the capacitor, a core assembly of the capacitor and the cover plate of the capacitor can be firmer and tighter, application is convenient, stability of the cover plate of the capacitor is improved, and the number of gaps which are formed in the capacitor after encapsulation is accomplished is reduced.
Description
Technical field
The present invention relates to a kind of plastic capacitor cover plate, belong to the capacitor technology field.
Background technology
At present, along with a large amount of exploitation of wind-force, solar energy, driven the development of wind-powered electricity generation photovoltaic electric container, generally the capacitor case of wind-powered electricity generation photovoltaic electric container is combined by epoxy sealing with capacitor cover plate.When the capacitor core group diameter is bigger than normal, space will likely occur between capacitor cover plate and capacitor core group, and this kind of situation will affect the useful life of capacitor.
Summary of the invention
The deficiency that the present invention exists for prior art just, provide a kind of plastic capacitor cover plate, and capacitor core group, capacitor case are coordinated with capacitor cover plate closely, to increase the useful life of capacitor.
For addressing the above problem, the technical solution used in the present invention is as follows:
A kind of plastic capacitor cover plate, comprise lid, and described lid is provided with annular lower edge, and the external diameter of described annular lower edge increases from bottom to up gradually.
As improvement of the technical scheme, described plastic capacitor cover plate also comprises reinforcement, described reinforcement is arranged at described lid bottom surface, and described reinforcement is many and arranges with the radial direction of described lid, and many described reinforcements mutually disjoint in the center of described lid.
As improvement of the technical scheme, the material of described lid and/or described reinforcement is the ABS flame retardant plastics.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
Plastic capacitor cover plate of the present invention, be mainly used in large capacity dry type DC filter capacitor; The material of described plastic capacitor cover plate is the ABS flame retardant plastics, is characterized in that combination property is better, and impact strength is higher, chemical stability, and electrical property is good; High-impact, high heat-resisting, fire-retardant, enhancing, the rank such as transparent are arranged, and mobility is not as good as HIPS, and better than PMMA, PC etc., pliability is good; In the plastic capacitor cover plate, inner reinforcement is only strengthened between electrode, has so not only played the effect of strengthening cover plate intensity, and, when the perfusion epoxy, can make the epoxy material better permeate, and reduces the space between capacitor core group and capacitor cover plate.
In sum, plastic capacitor cover plate of the present invention is by revising the reinforcement position, the intensity of capacitor cover plate itself is increased, and capacitor case, capacitor core group are combined more firmly closely with cover plate, application is convenient, increase the steadiness of capacitor cover plate, reduced the space of capacitor internal after the embedding.

Fig. 1 is plastic capacitor cover plate side structure schematic diagram of the present invention;
Fig. 2 is plastic capacitor cover plate plan structure schematic diagram of the present invention.
Embodiment
Content of the present invention is described below in conjunction with specific embodiments.
As shown in Figure 1-2, be plastic capacitor covering plate structure schematic diagram of the present invention.Plastic capacitor cover plate of the present invention, comprise lid, and described lid 1 is provided with annular lower edge, and the external diameter of described annular lower edge increases from bottom to up gradually; The annular lower edge of described lid 1 with capacitor case, capacitor core group engagement process in be subject to external force and deformation occur, the restoring force that the gap of combination and deformation have been filled in deformation strengthened capacitor cover plate and capacitor case, capacitor core group in conjunction with compactness.Also comprise reinforcement 2, described reinforcement 2 is arranged at described lid 1 bottom surface, and described reinforcement 2 is many and arranges with the radial direction of described lid 1, and many described reinforcements 2 mutually disjoint in the center of described lid 1; The stressed probability in capacitor cover plate center is higher, mechanical strength is comparatively weak, described reinforcement makes the intensity at capacitor cover plate center stressed place greatly improve, thereby improve capacitor cover plate bulk strength and useful life, and by the center at described lid 1, steam vent is set, the air of capacitor in perfusion is reinforced each zone that muscle 2 cuts apart during inserts can be circulated in the electrode region and by electrode mounting hole and discharge, thereby reduced the space of capacitor internal after the embedding.The material of described lid 1 and described reinforcement 2 is the ABS flame retardant plastics.
Above content is detailed description made for the present invention in conjunction with specific embodiments, can not assert that the concrete enforcement of the present invention only limits to these explanations.For those skilled in the art, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of protection of the invention.
