Abstract

To reliably prevent ingress of moisture to a connection between an electrical connecting cable or line to an electrical apparatus within a housing, the conductors of the cable or line are externally surrounded by an insulating layer which is of such a material that it joins, by melting or chemical reaction with the material of a surrounding bushing or sleeve, which bushing or sleeve then can be secured in a wall of the apparatus, for example by a removable rubber ring (FIG. 2) or can be molded into the housing of an electrical apparatus, for example a sensor; preferably, the materials of the housing and of the plug or sleeve also join, either by melting together or by chemical reaction. For a melt connection, a thermoplastic such as polyamide is suitable; for reactive connection, a reactive thermosetting plastic, for example polyester imide, or epoxy may be used.
