Abstract
A cable bushing in a housing for a device which may be a gas sensor and which may be connected to at least one connecting cable having an electrical conductor and cable insulation includes a molded body provided inside an opening of the housing and through which the at least one connecting cable is guided. The molded body has defined therein at least one bushing tube and has an outer cylindrical wall in which is defined a ring groove starting at one frontal side and extending axially inside the molded body, the at least one bushing tube and the ring groove being separated by an inner wall. The inner wall and the outer cylindrical wall of the molded body have respective thicknesses, and the thickness of the outer cylindrical wall is less than the smallest wall thickness of the inner wall. A support ring is positioned in the ring groove and serves as an outer support for wedging in the molded body into the opening of the housing. A method for producing the cable bushing includes inserting the at least one connection cable into the molded body while outside of the housing; subjecting the molded body and the inserted at least one connection cable to a heat treatment while outside of th…
