Definitions

  • This invention relates to a method of terminating so-called shielded electrical cable, that is cable comprising one or more insulated conductors contained within a common outer insulating jacket together with an uninsulated conductor known as the drain wire, and a metal foil shield surrounding the insulated conductors and the uninsulated conductor within the outer jacket, and in contact with the drain wire, and to an assembly comprising an electrical connector terminating such cable.
  • a type of electrical connector in common use is one using so-called insulation displacement terminals, such terminals having a conductor-connection portion comprising a pair of arms together defining a slot into which an insulated electrical conductor can be forced transversely of its axis, such that the edges of the slot penetrate the insulation of the conductor and establish an electrical connection to the conductive core thereof.
  • insulation displacement terminals often have an integrally formed second portion comprising a pair of arms together defining a second slot aligned with the slot of the conductor-connection portion, and into which the insulated conductor is forced as it is forced into the conductor-connection portion slot.
  • this second slot is wider than the conductor-connection slot such that the insulation of the conductor is merely gripped but not penetrated up to the conductive core of the conductor.
  • This second portion thus provides strain relief for the connection between the conductive core of the conductor and the conductor-connection portion slot, from forces applied to the conductor.
  • a difficulty which arises when such a connector using such insulation displacement terminals is to be used to terminate shielded cable as set out above, is that while the insulated conductors of the cable can be satisfactorily terminated by individual terminals each having a conductor-connection slot at which a connection is made to the conductive core of the conductor and a strain relief slot at which the insulation of the conductor is gripped, the uninsulated drain wire, while being satisfactorily gripped by the conductor-connection slot of its associated terminal, will be loose in the strain relief slot of the associated terminal if, as is desirable from a connector manufacturing point of view, all of the terminals of the connector have similar conductor-connection portions. Thus, the connection between the drain wire and the associated terminal will not have any strain relief facility, and the connection can be easily broken or the drain wire damaged.
  • a method of terminating shielded electrical cable as herein defined using an electrical connector having insulation displacement terminals each with a conductor-connection portion comprising a pair of arms together defining a slot into-which an insulated electrical conductor can be forced transversely of its axis such that the edge of the slot penetrate the insulation of the conductor.and establish an electrical connection to the conductive core thereof, and an integrally formed strain relief portion comprising a pair of arms together defining a slot aligned with the conductor-connection slot and into which the insulated conductor is forced as it is forced into the conductor-connection slot, the strain relief slot being wider than the conductor-connection slot such that the insulation of the conductor is gripped but not penetrated up to the conductive core of the conductor by the edges of the strain relief slot, characterised in that the drain wire of the cable is connected to a terminal of the connector by forcing the drain wire into the conductor-connection slot of the terminal to be gripped thereby with the drain wire extending through the strain relief slot of the terminal
  • the plug can be applied as a separate individual member, but is preferably cut from a strip of material, such "as a tube or solid strip of plastics material, and inserted into the strain relief slot simultaneously with connection of the drain wire and the insulated conductors of the shielded cable to their respective terminals of the connector by means, for example, of an automatic or semi-automatic machine.
  • the method of this invention has the advantage that the plug, by wedging the drain wire in the strain relief slot of the terminal connected thereto, provides strain relief for the connection between the drain wire and the conductor-connection slot of the terminal.
  • an assembly comprising an electrical connector terminating shielded electrical cable as herein defined, the connector having insulation displacement terminals all with identical conductor-connection portions, each such portion comprising a pair of arms together defining a slot in which an insulated electrical conductor of the cable is received transversely of its axis with the edges of the slot having penetrated the insulation of the conductor to establish an electrical connection to the conductive core thereof, and an integrally formed strain relief portion comprising a pair of arms together defining a slot aligned with the conductor-connection slot and in which the insulated conductor is received, the strain relief slot being wider than the conductor-connection slot such that the insulation of the conductor is gripped but not penetrated up to the conductive core of the conductor by the edges of the strain relief slot, characterised in that the drain wire of the cable is received in the conductor-connection slot of a terminal of the connector and is gripped thereby, the drain wire extending through the strain relief slot of the terminal with a plug of resilient material received in the strain relief
  • the drawing shows an electrical connector comprising a housing 1 moulded of electrically insulating plastics material and carrying a row of electrical terminals 2 each having a receptacle portion 3, shown mated with a terminal of another connector, and a conductor-connection portion 4.
  • This connector Is described in detail in British Patent Specification No. 1527035 and will not therefore be described in detail herein.
  • Each terminal 2.is stamped and formed from sheet metal, and the conductor-connection portion 4 comprises a conductor-connection slot 5 defined by a pair of arms 6 and into which an insulated conductor can be forced transversely of its axis such that the edges of the slot 5 penetrate the insulation of the conductor and establish an electrical connection to the conductive core thereof, and a strain relief slot 7 aligned with the slot 5 and also defined by a pair of arms 8, the slot 7 being wider than the slot 5 and receiving a portion of an insulated conductor forced into the slot 5, the slot 7 merely gripping the insulation of the conductor without penetrating up to the core thereof.
  • the drawing also shows a shielded electrical cable 9 comprising two insulated conductors 10 and an uninsulated drain wire 11 contained within a common insulating jacket 12, the conductors 10 and 11 being surrounded by an aluminium foil (not shown) also contained within the jacket 12 and in contact with the drain wire 11.
  • the insulated conductors 10 are connected to individual terminals 2 of the connector in known manner, and the drain wire 11 is also connected to an individual terminal 2 of the connector.
  • the drain wire 11 is received and gripped in the conductor-connection slot 5 of the associated terminal 2, and passes through the strain relief slot 7 of the terminal 2.
  • a plug 13 in the form of a short length of plastics material tubing is forced into the strain relief slot 7 of the terminal 2 associated with the drain wire 11, over the drain wire 11 therein, forcing the drain wire 11 to the bottom of slot 7, thus wedging the drain wire 11 and the plug 13 in the strain relief slot 7 thereby to provide strain relief for the connection between the drain wire 11 and the conductor-connection slot 5 of the associated terminal 2.
  • the conductors 10 and the drain wire 11 are all simultaneously connected to their respective terminals 2 by use of a machine which also cuts the plug 13 from a strip of plastics material tubing and inserts the plug 13 into the slot 7 simultaneously with the drain wire 11.
