Description
Technical field
The utility model relates to a kind of capacitor process equipment, specifically a kind of capacitor PTFE coated seal.
Background technique
It is a kind of novel storage that capacitor, which is called double layer capacitor (Electrical Double-Layer Capacitor),
It can device.Capacitor is the interfacial bilayer by being formed between electrode and electrolyte come the new component of storage energy.Usually
Electrolyte or electrolyte use liquid form, the design of capacitor generally includes shell, pole piece, insulated ring, sealing ring, upper cover
The interior media of capacitor is mainly sealed in capacitor to prevent its leakage by equal components, sealing ring.
The sealing means of capacitor casing and upper cover solve the sealing problem of capacitor using rubber seal technology, often
The problems such as sealing element of rule be easy to cause sealing element to distort during upper cover is with shell box cover, squeezes out, scuffing, leads to capacitor
Bad rate is higher for manufacture, meanwhile, the leakage failure for being easy to capacitor occur.Used sealing element will appear during the installation process
The failures such as distortion, scuffing, extrusion, fracture, cause the defect rate of product excessively high, capacitor is easy to appear leakage failure.
Utility model content
The purpose of this utility model is to provide a kind of capacitor PTFE coated seals, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of capacitor PTFE coated seal, including capacitor end cover board；The capacitor end cover board outer surface connects
It connects and is fixed with insulated ring；Capacitor aluminum barrel is equipped on the outside of the insulated ring；It is close that PTFE coating is equipped on the inside of the capacitor aluminum barrel
Sealing；The second insulated ring is equipped on the downside of the PTFE coated seal；Second insulated ring is located on the downside of capacitor end cover board,
Its downside is equipped with negative electrode tab；The negative electrode tab is located on the inside of capacitor aluminum barrel, and downside is equipped with electrolyte/electrolyte.
As a further solution of the present invention: the capacitor aluminum barrel nested encryptions are on the outside of capacitor end cover board,
And it is connected by insulated ring with capacitor end cover board.
As a further solution of the present invention: the PTFE coated seal is located on the outside of capacitor end cover board, by
Rubber elastic material is made, and outer surface and inner surface are covered by PTFE coating uniform.
Electrolyte/the electrolyte is filled in the second insulated ring, negative electrode tab as a further solution of the present invention,
It is formed by with capacitor aluminum barrel intracavitary.
Compared with prior art, the utility model has the beneficial effects that
