Abstract
An end cap connection assembly for use in connecting the metallic end caps of an electrical device such as current limiting fuses or lightning arrestors to associated insulative housings is provided which gives a strong mechanical bond as well as a leak-proof seal between these components. The connection assembly includes a cap presenting a continuous, annular, generally U-shaped in cross section housing-receiving groove, along with a relatively rigid synthetic resin sealing adhesive contacting both the groove walls and housing. The rigid adhesive is selected to have a heat distortion temperature closely matching that of the housing. Preferably, sealing material also has a thermal coefficient of expansion profile analogous to that of the housing. In this way the overall sealing assembly can successfully resist leakage resulting from thermal cycling. The sealing assembly of the invention completely eliminates the use of conventional O-rings, gaskets or similar expedients.
