ABSTRACT:
The invention relates to a method and an assembly kit for forming locally defined longitudinally water-tight sections in a wiring comprising a plurality of conductor strands, individual conductors and/or cable strands for the electric or electronic control of functions. Inserted between the conductor strands of such a wiring is a plastic element containing, or consisting of, a thermoplastic melt adhesive. This plastic element is caused to expand in response to being heated. A section of a heat-shrinkable component is mounted on the exterior of the wiring. Application of heat causes the shrinkable component to tightly contract around the wiring, and the plastic element positioned between the conductor strands to expand. The contraction of the heat-shrinkable component and the expansion of the plastic element result in the generation of pressure forces within the space enclosed by the heat-shrinkable component, whereby the heat-softened melt adhesive is sealingly forced into any existing voids.
