Definitions

  • the invention relates to a multiple splice seal, in particular special for use in a wiring harness in a motor vehicle or the like, for watertight, electrical connection of at least two pairs of wires, each pair of wires comprises a plurality of isolated insulated sheathed lines, which to avoid Interference or interference signals are twisted together, but at a kausbe rich are entdrillt, stripped at line ends and these ends of the line at least two separate

  • the individual lines of the line pairs are first of all undone or de-twisted by the other lines of a line pair and then the insulation is removed from the line ends of the individual lines.

  • the problem is the sealing several rer such in the installation position adjacent Spl mustbe rich, which preferably with two of these two enclosing the sleeves, in particular two Schrumpfschlau surfaces with inside adhesive, which encloses the splice regions in principle mutually insulating. During shrinkage, an undesired contact between the two splice regions can occur, which can lead to a short circuit.

As a particularly useful training as T- or double-U, C or X profile as insulation protection between the two splice regions (often referred to as "parallel connector” or through connector) or several ren splice has proven, preferably a Profile length of at least 30 mm, in order to avoid an electrical contact with each other already by the distance profile itself effectively.

Abstract

La présente invention concerne un joint à multiples épissures, en particulier pour la mise en œuvre dans un véhicule automobile ou analogue, pour la connexion électrique d'au moins deux paires de fils dans au moins deux zones d'épissures séparées, chaque paire de fils comportant plusieurs fils entourés chacun d'une gaine isolante, qui sont torsadés entre eux pour éviter des interférences ou des signaux parasites, mais non torsadés dans une zone de connexion, dénudés à des extrémités des fils et connectés dans au moins deux zones séparées d'épissure. Pour la fabrication séparée de manière électriquement active d'un connecteur parallèle avec au moins deux zones d'épissure, la présente invention emploie un profilé d'écartement, qui comporte au moins deux secteurs de maintien conçus pour la séparation électriquement isolante des au moins deux zones d'épissure, et un seul tube thermorétractable, contenant intérieurement de la colle, qui entoure de manière étanche et électriquement isolée le profilé d'écartement dans lequel sont placées les zones d'épissure.
