Abstract: Hermetically sealed electrical leads emanating from the neck portion of a conductive housing extend through a sleeve member that includes conductive and non-conductive parts. The sleeve member is dimensioned to firmly engage the neck portion of the housing. When so engaged, the electrical leads extend through longitudinal openings in the non-conductive part. In that way, a substantial extent of the leads is shielded. Moreover, the extent to which the leads can be laterally moved with respect to their hermetic seals is thereby significantly restricted.
