Abstract
The utility model discloses an engineering plastic housing capacitor which comprises a trough type housing, a core body and a soldering lug, a positioning rib is arranged at the bottom of an inner cavity of the trough type housing, a positioning slot is arranged in the mounting position of the soldering lug on the inner wall of the trough type housing, an elastic positioning pin is connected on the outer side of the soldering lug, the elastic positioning pin is resisted into the positioning slot, and the core body and the soldering lug are cured with the inner cavity of the trough type housing into a whole through epoxy resin. The engineering plastic housing capacitor has simple structure, and the core body can be completely enveloped, thereby avoiding the serious attenuation of capacitance and even the consequence of loss of capacitance due to moisturization and oxidation of the core body during the using process.
Description
Technical field:
The utility model relates generally to a kind of architecture advances of electric capacity, relates in particular to a kind of engineering plastics case capacitance device.
Background technology:
Engineering plastics case capacitance device is applicable to electric fan, ventilating fan and electric water pump etc., helps the startup and the operation of motor, and this product has that volume is little, insulation resistance is high, stable performance, shock-resistant electric current and the strong advantage of overload capacity.Existing engineering plastics case capacitance device is to be main dielectric material with polypropylene film, and the zinc-aluminium metal layer adopts no sensing mode coiling to form as electrode.The core body two ends as extraction pole, are Practical Performance and the security performance of guaranteeing product with weld tabs, the capacitor core body need be sealed in the plastic casing fully, and fill the potting compound embedding and protected between plastic casing and core body.Past, because the client does not have requirement placed in the middle for the core body of plastics electric capacity with weld tabs, core body is directly packed into after connecting weld tabs in the plastic casing, owing to have certain clearance between plastic casing and the core body, core body just crooked phenomenon may occur with respect to plastic casing, the core body that has is too tight owing to what contact with plastic casing, and potting compound just might wrap up less than core body.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of engineering plastics case capacitance device to be provided, and it is simple in structure, core body can be fixed on middle position in the plastic casing firmly.
The utility model is achieved through the following technical solutions:
A kind of engineering plastics case capacitance device, include the slot type housing, core body, weld tabs, it is characterized in that described slot type housing intracavity bottom has positioning bar, described slot type inner walls weld tabs installation place has location notch, the described weld tabs outside is connected with the elasticity angle, and described elasticity angle supports in the described location notch, and described core body, weld tabs are cured as one by epoxy resin and slot type housing inner chamber.
Weld tabs in the utility model cooperates plastic casing just in time to make core body be positioned at the center of plastic casing, behind the core body location, go up potting compound in the plastic casing and whole core body can be fixed on middle position in the plastic casing firmly, avoid occurring the not encapsulated good phenomenon of core body and take place.
The utility model has the advantages that:
Of the present utility model simple in structure, core body wherein can be sealed fully, and therefore, the utility model in use can not occur because of core body makes moist easily, oxidation, and causes the capacitance decay serious, until the consequence of turning pale.
Description of drawings:
Fig. 1 is the front view of capacitor casing.
Fig. 2 is the vertical view of capacitor casing.
Fig. 3 is the structural representation of capacitor weld tabs.
Embodiment:
A kind of engineering plastics case capacitance device, include slot type housing 1, core body, weld tabs 3, slot type housing 1 intracavity bottom has positioning bar 4, slot type housing 1 inwall weld tabs installation place has location notch 5, weld tabs 3 outsides are connected with elasticity angle 2, and elasticity angle 2 supports in the described location notch 5, and core body, weld tabs 3 are cured as one by epoxy resin and slot type housing 1 inner chamber.
