Description

Closed dampproofing condenser

Technical Field

The utility model relates to the technical field of capacitors, in particular to a closed moistureproof capacitor.

Background

The traditional capacitor is sealed through the aluminum shell and the cover plate, and the principle is that the opening of the aluminum shell is reversely buckled on the adhesive layer on the surface of the cover plate, and the product is sealed by controlling the adhesive entering depth of the aluminum shell.

The material of the leading-out end on the cover plate used at home and abroad at present is iron clad copper plated tin, the rivet connected with the inner core of the aluminum shell is aluminum, no protective layer exists outside, the cover plate is directly exposed in air, and electrochemical corrosion is extremely easy to form under the severe environmental conditions of acidity, humidity, salt fog, mould and the like.

The capacitor is miniaturized to the high pressure and develops, and the environment of application is more and more abominable, like marine, desert, photovoltaic power generation etc. and oxygen, moisture, sulfur dioxide, the acid-base gas in the air adsorb in aperture, the crack on metal surface, penetrate metal oxide layer and get into the inside metal and corrode, can cause following hidden danger at the humidity: corrosion can affect the tightness of the product, so that various performances of the product are reduced, and the service life is shortened; only one layer of ethylene propylene diene monomer with the thickness of 1mm is arranged on the cover plate, so that the cover plate is extremely easy to crack when external impact is applied, and the sealing performance and the service life of a product are influenced; rivets connected with the core on the cover plate are corroded, so that the resistance of the leading-out end is increased, the heat generation is increased, and even potential safety hazards such as explosion are avoided; the corrosion causes the breakage of the foil guiding strip, and the equipment can not provide stable output power, so that the safety of the whole machine is affected.

At present, the existing capacitor has poor sealing performance, and when the external moisture increases, the efficiency of the capacitor is affected, and even the capacitor is disabled.
