Abstract

A double-insulation capacitor comprises a tubular capacitor shell (10), a capacitor unit (20) embedded in the capacitor shell (10), a seal plate (30) for sealing an opening of the tubular capacitor shell (10), connecting pins (40) connected with the capacitor unit (20), a column part wrapping the tubular capacitor shell (10) and a marking insulating layer (50) of part of an end face. A insulating coating (60) is coated on the outer surface of the tubular capacitor shell (10). The marking insulating layer (50) is sleeved outside the insulating coating (60). By the structure, insulation of the whole outer surface of the capacitor can be achieved, insulation performance of the capacitor is improved, and normal operation of the capacitor is guaranteed powerfully.

Description

Double-insulated capacitor

Technical field

The utility model relates to electronic devices and components, particularly the design of capacitor internal structure.

Background technology

The shell of existing capacitor generally adopts an insulation of overcoat body, sign such as print capacitor parameter on this insulation body, still, this puies forward the cylinder part that body has only covered electric capacity extremely, and top that can not covering capacitor, because if cover this top section, the sign of the embodiment capacitor performance that the top arranges is blocked and is not easy to be found, under actual working environment, often the top also might touch the impact of electric power very much, and therefore, the top insulation is also considerably important.

Summary of the invention

The utility model provides a kind of double insulated capacitor, adopts the mode that applies insulating material, not only the cylinder part of capacitor for voltage protection; but also can protect the top; simultaneously, do not influence the performance of observing capacitor again, solve the not good technical problem of insulation in the prior art.

The utility model is to solve the problems of the technologies described above the capacitor case that this double hyer insulation capacitor that designs comprises tubbiness, be flush-mounted in the capacitor cell in this capacitor case, the capping plate of the described capacitor case opening of capping and the connecting pin that connects described capacitor cell, the sign insulating barrier that also comprises the described capacitor case cylinder part of parcel and part end face, on the outer surface of described capacitor case, also be coated with one deck coatings, described sign insulating barrier is sheathed on the outside of described coatings, described coatings only is coated on the outer surface at capacitor case top, and perhaps described coatings is coated on the outer surface of capacitor case cylinder and top section.

The utility model adopts above-mentioned structural design, and the whole outer surface that insulation can covering capacitor has improved the insulation property of capacitor, powerful guarantee the operate as normal of capacitor.

Description of drawings

Fig. 1 is the perspective exploded view of the utility model capacitor.

Fig. 2 is the cross-sectional schematic of the utility model capacitor.

Embodiment

In conjunction with above-mentioned description of drawings specific embodiment of the utility model.

By among Fig. 1 and Fig. 2 as can be known, this double-insulated capacitor comprises the capacitor case 10 of tubbiness, the capping plate 30 that is flush-mounted in described capacitor case 10 openings of capacitor cell 20, capping in this capacitor case 10 and the connecting pin 40 that connects described capacitor cell 20, the sign insulating barrier 50 that also comprises the described capacitor case 10 cylinders part of parcel and part end face, also be coated with one deck coatings 60 on the outer surface of described capacitor case 10, described sign insulating barrier 50 is sheathed on the outside of described coatings 60.The utility model has been set up a layer insulating, not have the zone that covers, the insulation property of raising capacitor integral body for the protection of the insulation body.

Described coatings 60 only is coated on the outer surface at capacitor case 10 tops, and perhaps described coatings 60 is coated on the outer surface of capacitor case 10 cylinders and top section.

Above content be in conjunction with concrete preferred implementation to further describing that the present invention does, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
