Method for forming a water-tight section in a predetermined area of a multi-conductor wiring system

摘要

A method for forming a longitudinally water-tight section in a predetermined area of a multi-conductor wiring system. The multi-conductor wiring system has a plurality of individual conductors, each individual conductor being encased in an insulative sheath. The method includes the steps of: providing an adherent tape having a single sealing compound for adhering the individual conductors thereto and for sealing spaces between the individual conductors when exposed to a softening temperature less than the softening temperature of the insulative sheathes of the individual conductors; arranging the individual conductors parallel to one another in a direction transverse to the adherent tape in the predetermined area on a first end of the adherent tape; folding a second end of said adherent tape onto the conductors such that the individual conductors are sandwiched therebetween; pressing the first and second ends of the adherent tape together to sealingly fill the spaces between the conductors; heating the sealing compound to the softening temperature of the sealing compound; and applying an outer envelope over the sealed predetermined area. In a variation of the method of the present invention, the method further includes the step of compressing the sealing compound at an elevated pressure while being heated to the softening temperature such that pores, voids and gases in the sealing compound are substantially removed.
