Abstract
The utility model provides a tank cover sealing mechanism of a capacitor impregnation tank, which comprises a tank body and a tank cover, wherein the top of the tank body is provided with a primary sealing groove formed by sinking, the bottom of the tank cover is provided with a sealing ring formed by sinking, the top of the inner ring surface of the sealing ring horizontally extends inwards to form a lap joint ring, the inner ring position of the lap joint ring extends downwards to form an inner sealing ring, and a secondary sealing groove is reserved between the outer ring surface of the inner sealing ring and the inner ring surface of the sealing ring. Rational in infrastructure, excellent in use effect after this scheme of adoption.
Description
Technical Field
The utility model relates to the technical field of capacitors, in particular to a tank cover sealing mechanism of a capacitor impregnation tank.
Background
The capacitor is one of the electronic elements widely used in electronic equipment, and is widely applied to the aspects of blocking, direct current and alternating current, coupling, bypass, filtering, tuning loop, energy conversion, control and the like in a circuit, and the solid capacitor adopting the conductive high polymer material as the dielectric material is more widely applied due to the problems of liquid electrolytic capacitor and the higher and higher requirements of the development of capacitor industry on product quality. The production of solid capacitor includes cutting, nailing and rolling, assembling with glue cover, welding, formation, impregnation, polymerization, sealing, soaking, stamping, aging, appearance inspection, cutting and packaging, the core bag impregnation of the traditional capacitor is mainly that the core bag is directly put into a container filled with impregnation liquid for soaking for a long time, so that the impregnation liquid permeates into positive foil, negative foil and paper, when the capacitor is impregnated, the tank body and the tank cover are sealed by a single-layer sealing ring (ring), after the sealing by the method, once the sealing ring (ring) is slightly worn, the internal pressure of the tank body is large and can permeate out from the sealing position, thereby greatly influencing the impregnation effect of the capacitor.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide the sealing mechanism for the cover of the capacitor impregnation tank, which has a reasonable structure and a good using effect.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the utility model provides a capacitor contains jar cover sealing mechanism that contains, it is including a jar body, cover, jar body top is equipped with recessed one-time seal groove that forms, and the cover bottom is equipped with the sealing ring that forms down, and the inside horizontal extension in sealing ring inner ring face top forms the overlap joint ring, and overlap joint ring inner ring department downwardly extending forms interior seal ring, reserves the secondary seal groove between interior seal ring outer anchor ring face and the sealing ring inner ring face.
And a secondary sealing rib is reserved at the top of the tank body on the inner side of the primary sealing groove and is matched with the secondary sealing groove for use.
The sealing ring is made of rubber or silica gel materials.
The sealing ring, the lapping ring and the inner sealing ring are integrally formed.
After the scheme is adopted, the tank body and the tank cover are buckled, the sealing ring is embedded into the primary sealing groove to form primary sealing, the lapping ring and the inner sealing ring are tightly attached to the top of the secondary sealing rib and the inner cavity wall, so that secondary sealing is formed, the primary sealing and the secondary sealing are mutually matched to form multiple bending, the sealing effect is greatly improved, and the structure is reasonable and the using effect is good after the scheme is adopted.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of the seal ring structure of the present invention.
Detailed Description
The utility model will be further described with reference to the accompanying drawings, in which preferred embodiments of the utility model are: referring to fig. 1 and 2, the tank cover sealing mechanism of the capacitor impregnation tank in the embodiment includes a tank body 1 and a tank cover 2, a primary sealing groove 3 formed by sinking is formed in the top of the tank body 1, a secondary sealing rib is reserved at the top of the tank body 1 on the inner side of the primary sealing groove 3, and the secondary sealing rib is used in cooperation with the secondary sealing groove. The bottom of the tank cover 2 is provided with a sealing ring 4 formed by a downward bulge, and the sealing ring 4 is made of rubber or silica gel material. The top of the inner ring surface of the sealing ring 4 extends inwards horizontally to form a lap joint ring 5, the inner ring of the lap joint ring 5 extends downwards to form an inner sealing ring 6, and a secondary sealing groove is reserved between the outer ring surface of the inner sealing ring 6 and the inner ring surface of the sealing ring 4. The sealing ring 4, the lapping ring 5 and the inner sealing ring 6 are integrally formed. After adopting above-mentioned scheme, this embodiment, jar body and cover lock back, the sealing ring forms once sealedly with a seal groove gomphosis, and top and the inner chamber wall of secondary seal rib are hugged closely to overlap joint ring, interior seal ring to form secondary seal, once sealed, secondary seal mutually support and form bending many times, thereby greatly increased seals the effect, rational in infrastructure, excellent in use effect after adopting this embodiment.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the changes in the shape and principle of the present invention should be covered within the protection scope of the present invention.
