Description
Technical field
The present invention relates to electric utility field, more particularly to a kind of waterproof capacitor.
Background technology
At present, electric capacity is called in the usual letter of existing capacitor, is " container of dress electricity ", is a kind of device for accommodating electric charge
Part.Electric capacity is one of a large amount of electronic components used in electronic equipment, the separated by direct communication being widely used in circuit, is coupled,
Bypass, filtering, resonant tank, energy conversion, control etc..One layer of lid is installed between capacitor body and external environment
Plate, inside sealed capacitor, prevent from contacting with external environment, be also used for mounting and dismounting capacitor, but capacitor by
The change of temperature is obvious, for example expands with heat and contract with cold, therefore gap will occur with shell in cover plate, the capacitor of prior art
Seal point is concentrated mainly on the junction of cover plate and shell, have ignored the sealing of pad on cover plate, therefore this capacitor
It can not be worked in a liquid because of poor sealing, working environment is restricted, and flexibility is low, while dielectric does not have yet
Good waterproof effect, and housing cavity is typically square structure, if capacitor internal expanded by heating, inner chamber stress intensity
It is low, it is excessive to housing pressure, easily cause outer casing rupture.
Therefore, in order to solve above-mentioned problem, spy of the present invention provides a kind of new technical scheme.
The content of the invention
It is an object of the invention to provide it is a kind of be used in liquid, the big waterproof capacitor of stress intensity.
Technical scheme is used by the present invention is directed to above-mentioned technological deficiency：
A kind of waterproof capacitor, including housing, capacitor core module, lead and cover plate, peace is sealed in the case top
Equipped with a cover plate, an inner chamber is provided with the housing, a capacitance core submodule being made up of capacitor core unit is installed in inner chamber
Block, the capacitor core module top connect top crown, and the capacitor core module bottom connects bottom crown, upper and lower pole plate point
Two leads are not led to, and the cover plate is provided with the pad of anchor leg and positive and negative electrode, is provided with the cover plate more
Layer rubber gasket sheet, is filled with dielectric between the inner chamber and insulation crust.
Further, the dielectric is insulation silicone grease.
Further, the seamless sealed connection of fluid sealant is passed through between rubber gasket sheet.
Further, pureed soft packing is cast with around the pad.
Further, the side of inner chamber four is inwardly arched upward, and four sides are respectively formed domes.
The beneficial effects of the invention are as follows：The present invention using insulation silica gel as dielectric, waterproof and perfect heat-dissipating, together
When cover plate on be sealed and installed with multilayer rubber sealing plate, use the seamless sealed connection of fluid sealant between rubber gasket sheet, and
Pad pours into a mould pureed soft packing, multi-sealed, realizes that entirety seals without dead angle, avoids liquid and dust from entering in capacitor
Portion causes the phenomenon of electric leakage, and the domes on the side of inner chamber four, improves the stress intensity of inner chamber, reduces because of expanded by heating
To the pressure of housing, the service life of capacitor is improved.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
Wherein：1st, housing, 2, capacitor core module, 3, top crown, 4, bottom crown, 5, lead, 6, cover plate, 7, pad,
8th, insulate silicone grease, and 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, including housing 1, capacitor core module 2, lead 5 and cover plate 6, housing 1
Sealed on top is provided with a cover plate 6, and an inner chamber 101 is provided with housing 1, one is provided with by capacitor core unit in inner chamber 101
The capacitor core module 2 of composition, the top of capacitor core module 2 connection top crown 3, the bottom of capacitor core module 2 connection bottom crown
4, upper and lower pole plate 3,4 leads to two leads 5 respectively, and cover plate 6 is provided with the pad 7 of anchor leg and positive and negative electrode, cover plate
Multilayer rubber sealing plate 10 is installed on 6, dielectric is filled between inner chamber 101 and insulation crust 9.
Wherein, dielectric is insulation silicone grease 8, ageing-resistant, has excellent waterproof and moisture resistance energy, can prevent
Water, dust enter sealing position, and the perfect heat-dissipating of silicone grease 8 that insulate, safe to use.By close between rubber gasket sheet 10
Sealed connection that sealing is seamless, it is multi-sealed, after the completion of contact 7 to be welded welds, pureed soft packing is cast with around pad 7
11, have no to wear to cover plate 6 and pad 7, the effect of complete No leakage can be reached, multilayer rubber sealing plate 10 is sealed into peace
On cover plate 6, good sealing function, the gap between salable cover plate 6 and housing 1, sealing effect can be realized to housing 1
Fruit is good.
In addition, the side of inner chamber 101 4 is inwardly arched upward, four sides are respectively formed domes, improve all directions of inner chamber 101 by
Force intensity, reduce the pressure to housing 1 because of capacitor internal expanded by heating, improve the service life of capacitor.
The beneficial effects of the invention are as follows：Waterproof and perfect heat-dissipating of the present invention, it is multi-sealed, realize overall close without dead angle
Envelope, and the domes on the side of inner chamber four, improve the stress intensity of inner chamber, service life length.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
