Abstract
Abstract A cable bushing which is small, simple and cost-effective as possible, having a cable, a housing, though which the cable is led, and which has a radially inwardly extending step at its first end, a first sleeve, which engages around the cable and which has a first section arranged inside the housing. The first sleeve is held by the step in the housing, the first sleeve bearing in a seal-forming fashion against the cable and there being a sealing means between the step in the housing and the fist sleeve. A second sleeve is arranged in the interior of the housing and has a first cylindrical section which engages closely around the cable, the first sleeve having a second section which adjoins an end of the first section which faces the step, said second section bearing on the first section of the first sleeve, and an attachment element by means of which the second sleeve is pressed against the first sleeve.
