Abstract
The invention discloses a waterproof capacitor. The waterproof capacitor comprises a shell, a capacitor core module, leads and a cover plate; an inner cavity is formed in the shell; the capacitor core module formed by a capacitor core unit is mounted in the inner cavity; a polar plate is connected with the upper part and the lower part of the capacitor core module separately; two leads are connected with the upper ends of the polar plates; welding points for fixing the leads and positive and negative electrodes are arranged on the cover plate; multiple layers of rubber sealing plates are mounted on the cover plate; and the space between the inner cavity and the insulating shell is filled with an insulating medium. The waterproof capacitor takes insulating silica gel as the insulating medium, so that the capacitor is good in waterproof and radiating performances; the multiple layers of rubber sealing plates are connected in a seamless sealing manner by sealant, and muddy soft stuffing is poured in the welding points, so that the waterproof capacitor is sealed in multiple modes, and the overall capacitor is sealed without dead corners; and in addition, the four edges of the inner cavity of the capacitor are arch-structured, so that the stress strength of the inner cavity is improved, and the service life of the capacitor is prolonged.
Description
Technical field
The present invention relates to electric installation field, particularly relate to a kind of waterproof capacitor.
Background technology
At present, electric capacity is called in the usual letter of existing capacitor, and being " container of dress electricity ", is a kind of device holding electric charge.Electric capacity is one of electronic component of a large amount of uses in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.One deck cover plate is installed between capacitor body and external environment, for sealed capacitor inside, prevent from contacting with external environment, also be used for mounting and dismounting capacitor, but capacitor is obvious by the change of temperature, such as expand with heat and contract with cold, therefore will there is gap with shell in cover plate, the seal point of the capacitor of prior art mainly concentrates on the junction of cover plate and shell, have ignored the sealing of pad on cover plate, therefore this capacitor can not work in a liquid because of poor sealing, operational environment is restricted, flexibility is low, dielectric does not have good waterproof effect yet simultaneously, and housing cavity normally square structure, if capacitor internal expanded by heating, inner chamber is low by force intensity, excessive to housing pressure, easily cause outer casing rupture.
Therefore, in order to solve above-mentioned Problems existing, the present invention spy provides a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of in liquid, by the large waterproof capacitor of force intensity.
The present invention is directed to the technical scheme that above-mentioned technological deficiency adopts is:
A kind of waterproof capacitor, comprise housing, capacitor core module, lead-in wire and cover plate, described case top is sealed and installed with a cover plate, an inner chamber is provided with in described housing, the one capacitor core module be made up of capacitor core unit is installed in inner chamber, described capacitor core module top connects top crown, described capacitor core module bottom connects bottom crown, on, bottom crown leads to two lead-in wires respectively, described cover plate is provided with the pad of anchor leg and positive and negative electrode, described cover plate is provided with multilayer rubber sealing plate, dielectric is filled with between described inner chamber and insulation crust.
Further, described dielectric is insulation silicone grease.
Further, be tightly connected by fluid sealant is seamless between rubber gasket sheet.
Further, pureed soft packing is cast with around described pad.
Further, inwardly arch upward in described inner chamber four limit, four limits all form domes.
The invention has the beneficial effects as follows: the present invention adopts insulation silica gel as dielectric, waterproof and perfect heat-dissipating, cover plate is sealed and installed with multilayer rubber sealing plate simultaneously, be tightly connected with fluid sealant is seamless between rubber gasket sheet, and in the soft packing of pad cast pureed, multi-sealed, realize entirety to seal without dead angle, avoid liquid and dust enter into capacitor internal cause leak electricity phenomenon, and the domes on inner chamber four limit, what improve inner chamber is subject to force intensity, decreases because expanded by heating is to the pressure of housing, improves the useful life of capacitor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, housing, 2, capacitor core module, 3, top crown, 4, bottom crown, 5, lead-in wire, 6, cover plate, 7, pad, 8, insulation silicone grease, 9, insulation crust, 10, rubber gasket sheet, 11, pureed soft packing, 101, inner chamber.
Embodiment
A kind of waterproof capacitor as shown in Figure 1, comprise housing 1, capacitor core module 2, lead-in wire 5 and cover plate 6, housing 1 sealed on top is provided with a cover plate 6, an inner chamber 101 is provided with in housing 1, the one capacitor core module 2 be made up of capacitor core unit is installed in inner chamber 101, capacitor core module 2 top connects top crown 3, capacitor core module 2 bottom connects bottom crown 4, on, bottom crown 3, 4 lead to two lead-in wires 5 respectively, cover plate 6 is provided with the pad 7 of anchor leg and positive and negative electrode, cover plate 6 is provided with multilayer rubber sealing plate 10, dielectric is filled with between inner chamber 101 and insulation crust 9.
Wherein, dielectric is insulation silicone grease 8, ageing-resistant, has excellent waterproof and blocks moisture performance, anti-sealing, dust can enter into sealing position, and insulation silicone grease 8 perfect heat-dissipating, use safety.Be tightly connected by fluid sealant is seamless between rubber gasket sheet 10, multi-sealed, after contact 7 to be welded has welded, around pad 7, be cast with pureed soft packing 11, wearing and tearing had no to cover plate 6 and pad 7, complete leak free effect can be reached, multilayer rubber sealing plate 10 sealing is arranged on cover plate 6, good sealing function can be realized, the gap between salable cover plate 6 and housing 1, good sealing effect to housing 1.
In addition, inwardly arch upward in inner chamber 101 4 limit, four limits all form domes, and what improve inner chamber 101 all directions is subject to force intensity, decreases because capacitor internal expanded by heating is to the pressure of housing 1, improves the useful life of capacitor.
The invention has the beneficial effects as follows: waterproof of the present invention and perfect heat-dissipating, multi-sealed, realize overall without dead angle sealing, and the domes on inner chamber four limit, what improve inner chamber is subject to force intensity, long service life.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
