Sealing cover with a bushing element

摘要

The invention relates to a sealing cover for sealing cup-shaped housings of electrical components, especially cup-shaped capacitors having at least one electrically conductive bushing element. In contrast to known sealing covers, the attachment of the bushing element is achieved by means of rivet-like expansion of the bushing element itself in the covering disk. The rivet-like expansion takes place in the manner of cutting material away, whereby a complete annular projection is achieved which forms a compression sealing contact with a sealing insert which clads the bushing opening. For multiple bushings, the bushing element is secured in terms of rotation. The bushing element, which is provided in the sealing cover, is designed in such a manner that it can be used on one side as a multiple rivet-like closing-head connection for fixing the bushing element in the cover and for the further attachment of, for example, solder tabs. <IMAGE>
