Abstract

The utility model discloses a plastic capacitor cover plate comprising a cover body. The cover body is provided with an annular lower edge, and the outer diameter of the annular lower edge gradually increases from bottom to top; and the plastic capacitor cover plate further comprises a plurality of reinforcing ribs, the reinforcing ribs are disposed on the bottom surface of the cover body, the reinforcing ribs are arranged in radius directions of the cover body, and the plurality of the reinforcing ribs are not intersected to each other at a center position of the cover body. According to the plastic capacitor cover plate, the strength of the capacitor cover plate itself is increased, a capacitor housing and a capacitor core group can be combined more firmly and tightly, convenience is provided for application, the stability of the capacitor cover plate is enhanced, and gaps in the capacitor after encapsulation are reduced.

Description

A kind of plastic capacitor cover plate

Technical field

The utility model relates to a kind of plastic capacitor cover plate, belongs to 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 capacitor core group diameter is bigger than normal, between capacitor cover plate and capacitor core group, will likely occur space, and this kind of situation will affect the useful life of capacitor.

Summary of the invention

The deficiency that the utility model exists for prior art just, provides a kind of plastic capacitor cover plate, capacitor core group, capacitor case is coordinated closely, to increase the useful life of capacitor with capacitor cover plate.

For addressing the above problem, technical solution adopted in the utility model is as follows:

A plastic capacitor cover plate, comprises 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.

Improvement as technique 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 the improvement of technique scheme, the material of described lid and/or described reinforcement is ABS flame retardant plastics.

Compared with prior art, implementation result of the present utility model is as follows for the utility model:

Plastic capacitor cover plate described in the utility model, is mainly used in large capacity dry type DC filter capacitor; The material of described plastic capacitor cover plate is ABS flame retardant plastics, is characterized in that combination property is better, and impact strength is higher, chemical stability, and electrical property is good; Have high-impact, high heat-resisting, fire-retardant, enhancing, the rank such as transparent, mobility is not as good as HIPS, better than PMMA, PC etc., and pliability is good; In 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 perfusion epoxy, can make epoxy material better permeate, and reduces the space between capacitor core group and capacitor cover plate.

In sum, plastic capacitor cover plate described in the utility model is by revising 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 embedding.

Embodiment

Content of the present utility model is described below in conjunction with specific embodiments.

As shown in Figure 1-2, be plastic capacitor covering plate structure schematic diagram described in the utility model.Plastic capacitor cover plate described in the utility model, comprises 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 combination compactness that the gap of combination and the restoring force of deformation have been strengthened capacitor cover plate and capacitor case, capacitor core group has been filled in deformation.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 improves the intensity at capacitor cover plate center stressed place greatly, 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 region that muscle 2 cuts apart during inserts can be circulated in electrode region and by electrode mounting hole and discharge, thereby reduced the space of capacitor internal after embedding.The material of described lid 1 and described reinforcement 2 is ABS flame retardant plastics.

Above content is the detailed description of in conjunction with specific embodiments the utility model being done, and can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
