Cable Bushing

Abstract

A cable bushing is disclosed for placement into a control housing surrounding a printed circuit board. The cable bushing includes a bushing housing comprising a locating surface, fastening means for fastening the bushing housing to the control housing, and retainers for at least two cables which are to be electrically connected to the printed circuit board. To facilitate the assembly of the cable bushing, the cable bushing housing is provided with contact elements that protrude from its front face, that are embodied to be adapted for plug contacting the printed circuit board, and that are electrically connected to the associated cables within the bushing housing.
