Abstract
A method for the manufacture of a housing (1) for an electrical connection system between parts that can be rotated with respect to each other, in particular between a steering wheel and a steering column, comprising a stationary housing part (3) and a housing part (4) which can be rotated relative with respect thereto, each of housing parts supporting a connector unit (10) and enclosing a spirally wound flexible electrical conductor (6) connected on its ends with connector units (10). The internal axial boundary surfaces (8) of the housing parts (3, 4) are provided with an insulating material (9). The insulating material (9) is a plastic material exhibiting sound-absorbing properties and is extrusion-coated on the internal axial boundary surfaces (8) of the plastic injection-molded housing parts (3, 4).
