ABSTRACT:
A bushing for leading an electrical connector through a wall or the like has an intermediate flange for attachment in the wall and two metallic end flanges on either side of the intermediate flange. Two hollow insulating bodies are clamped between the intermediate flange and the end flanges, and a bushing conductor runs the length of the bushing. The bushing conductor is movable in relation to the remainder of the bushing or at least in relation to one of the end flanges. A drawing member is connected between the end flanges and is composed of first and second elongated metallic bodies each of which is attached to the corresponding end flanges overlapping each other for a certain distance. A pressure transmitting member, which is formed of a material with a greater coefficient of thermal expansion than the first and second metallic bodies, forms a power transmitting connection between the free ends of the metallic bodies.
