Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1, a dielectric-filled capacitor comprises a capacitor shell 7, and a corresponding capacitor element 6 and a filling medium which are arranged in the capacitor shell 7, wherein the filling medium comprises a black glue 4 and a microcrystalline wax 5, the bottom and the top of the capacitor shell 7 are sealed by the black glue 4, and the microcrystalline wax 5 is arranged between the bottom and the top of the capacitor shell 7 for filling.
An upper cover 2 is arranged above the black glue 4 on the top of the capacitor shell 7.
And the upper cover 2 is provided with a corresponding wiring terminal 1.
And a base 8 is arranged below the black glue 4 at the bottom of the capacitor shell 7.
The inside of the vertical corner of the capacitor shell 7 is provided with a grounding column 3, the upper end of the grounding column 3 is connected to the upper cover 2, and the lower end is connected to the base 8.
The principle of the utility model
Under normal conditions, the whole product of the utility model is in a solid state, when the product is in a high temperature environment, because the melting point of the black glue 4 is high, even if the microcrystalline wax 5 is melted, the black glue 4 is still in a solid state, thus no leakage is generated, and when the temperature is high, because the microcrystalline wax 5 is in a liquid state, the heat dissipation of the capacitor is not influenced; even the condenser temperature is too high, leads to the ebonite 4 to melt, because the utility model discloses a structure, the thermal convection that produces this moment can make micrite wax 5 and ebonite 4 fully fuse, and the mixture at this moment has changed micrite wax 5's easy permeability, has remain the good thermal diffusivity of micrite wax 5 again. Therefore, the leakproofness and the thermal diffusivity of condenser can pass through the utility model discloses a structure reaches.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
