Definitions

  • the invention relates to an electrical connection between a terminal and a multilayer cable comprising a first layer of elongate conductors located in spaced parallel relation and a second conductive layer, spaced from the first layer, both layers being completely embedded in insulating material.
  • the second conductive layer may constitute a shield and comprise a mesh or series of relative fine, conductive strands or a conductive foil.
  • An electrical connection between a terminal and a multilayer cable comprising a first layer of elongate conductors located in spaced, parallel relation and a second conductive layer, spaced from the first layer, both layers being completely embedded in insulating material, the terminal having a contact portion and a conductor-connecting portion at respective opposite ends, the conductor-connector portion comprising a pair of insulation penetrating blades defining between them a conductor-receiving slot and being pointed at their free ends, the conductor-connecting portion having been forced into the cable so that a conductor of the first layer is jammed in the slot with the edges of the blades defining the slot establishing electrical connection to the conductor, according to the invention is characterised in that the blades have an insulating coating adjacent their free ends which penetrate the second conductive layer, the insulating coating ensuring that there is no electrical connection between the second conductive layer and the terminal.
  • the entire surface of the blades has been coated with insulation, portions of which have been rubbed from the edges of the blades defining the slot by movement of the conductor into the slot.
  • the first example of terminal 11 is similar to that described in U.S. Patent No. 3,820,055 and is stamped from sheet metal to provide a contact portion 12 and a conductor-connecting portion 13 at respective opposite ends of a body portion 15.
  • the conductor-connecting portion 13 comprises a pair of insulation penetrating blades 14 pointed at their free ends and defining between them a conductor-receiving slot 16.
  • the conductor-connecting and wire-receiving portions are coated with insulation 17.
  • the multilayer cable 18 is of conventional construction and comprises a first layer of elongate wires 19 located in spaced, parallel relation and a second conductive layer 20 of relatively fine wires spaced from the first layer, both layers being completely embedded in insulating material.
  • Connection between a conductor 19 and a terminal 11 is effected by urging the cable and terminal relatively together so that the blades penetrate the cable insulation and the conductor is forced into the slot 16.
  • the conductor 19 rubs away portions of the insulation 17 at the slot edges enabling electrical connection to be established between the terminal and the conductor.
  • the terminal insulation 17 prevents undesirable electrical connection between the terminal and the shield.
  • terminals will be mounted in an insulating housing for application to the cable as described in the above-mentioned specification.
  • the terminals may be coated with one of several materials including polyesters, vinyls, urethane, enamels, acrylics, metallic oxides, nylon epoxy and epoxy phenolic resins.
  • the coating may be made using one of several methods including dipping, spraying, passing through a fluidized bed of powdered material, plating and electrodeposition.

Claims (2)

1. Connexion électrique entre une borne (11) et un câble multicouche (18) comprenant une première couche de conducteurs allongés (19) placée en une disposition parallèle, espacée, et une seconde couche conductrice (20), espacée de la première couche, les deux couches étant totalement enrobées de matière isolante, la borne ayant un tronçon (12) de contact et un tronçon (13) de connexion à un conducteur à des extrémités opposées respectives, le tron-' çon de connexion à un conducteur comprenant deux lames (14) de. pénétration d'isolation définissant entre. elles une fente (16) de réception d'un conducteur et pointues à leurs extrémités libres, le tronçon de connexion à un conducteur ayant été forcé dans le câble de manière qu'un conducteur de la première couche soit coincé dans la fente, les bords des lames définissant la fente établissant une connexion électrique sur le conducteur, caractérisée en ce que les lames (14 ou 21) ont un revêtement isolant (17 ou 23) à proximité de leurs extrémités libres qui pénètrent dans la seconde couche conductrice (20), le revêtement isolant (17 ou 23) empêchant toute connexion électrique entre la seconde couche conductrice (20) et la borne (11 ou 22).
2. Connexion électrique selon la revendication 1, caractérisée en ce que pratiquement la totalité de la surface des lames (14) a été revêtue d'une isolation (17), dont certaines parties ont été retirées par frottement des bords des lames (14) définissant la fente (16) par le mouvement du conducteur (19) vers l'intérieur de la fente (16).
