US 9,006,589 B2 · Cable bushing

Abstract

A cable bushing, in particular for a motor vehicle, for routing a cable harness having a plurality of electrical lines through a wall opening in a sealed manner. The cable bushing includes a dimensionally stable housing for insertion into the wall opening. The housing encloses a sealing member that is made of an elastic sealing material. The sealing member includes receiving devices or channels for individually routing the electrical lines in an axial direction. The cable bushing further has a pressure-providing element that exerts a compressive force on the sealing member, such that the sealing member encloses the electrical lines individually in a sealed manner and the sealing member is pressed radially against the housing to achieve a high level of impermeability to longitudinal water penetration. Additionally, pins may be provided to produce additional radial compressive forces.

Dependent claims

A cable bushing for providing sealed routing of a cable harness having a plurality of electrical lines through an opening, the cable bushing comprising:

a dimensionally stable housing for being inserted into the opening;
a sealing element of elastic sealing material enclosed by said housing and having an opening:
a plurality of receiving devices disposed in said sealing element for individually routing the electrical lines in an axial direction;
a pressure-providing element for exerting a compressive force on said sealing element such that the sealing material is displaced in a radially outward direction;
and
said pressure-providing element including pins to be engaged in the openings for displacing the sealing material in the radially outward direction, said openings and said pins extending perpendicular with respect to the axial direction.
