Abstract

L'invention concerne un bloc terminal hermétiquement joint et un procédé pour sa fabrication. On encapsule au moins un terminal électriquement conducteur ayant un coefficient de dilatation thermique relativement grand au sein d'un boîtier façonné en une matiere non conductrice ayant un coefficient de dilatation thermique relativement faible. Le terminal comprend des surfaces radiales axialement espacées qui sont en contact avec des surfaces radiales opposées formées dans le boîtier. Lorsque l'on chauffe le boîtier et le terminal au cours du processus de moulage et qu'on refroidit ensuite, le mouvement relatif du terminal par rapport au boîtier donne lieu dans les surfaces radiales du terminal à la génération d'une force de compression contre les surfaces radiales opposées du boîtier. On évite avec un joint étanche de ce genre, des fuites de fluides le long de l'interface entre le boîtier et le terminal.The invention relates to a hermetically sealed terminal block and a method for its manufacture. At least one electrically conductive terminal having a relatively large coefficient of thermal expansion is encapsulated within a housing formed of a non-conductive material having a relatively low coefficient of thermal expansion. The terminal includes axially spaced radial surfaces which contact opposing radial surfaces formed in the housing. When the housing and terminal are heated during the molding process and then cooled, the relative movement of the terminal relative to the housing gives rise in the radial surfaces of the terminal to the generation of a compressive force against. the opposing radial surfaces of the housing. Fluid leaks along the interface between the housing and the terminal are avoided with a tight seal of this type.
