Definitions

  • This invention relates to an electrical connector.
  • an electrical connector which comprises an electrical terminal having a contact end and a crimping ferrule for connection to an electrical conductor, the crimping ferrule being received in a metal sleeve which extends beyond the end of the crimping ferrule in the direction away from the contact end of the terminal, the metal sleeve in turn being received in an outer sleeve of electrically insulating material.
  • a bared end portion of the conductor of an insulated electrical conductor is inserted into the crimping ferrule of the terminal through the metal sleeve, with an insulated portion of the conductor positioned in the portion of the metal sleeve which extends beyond the crimping ferrule of the terminal.
  • the crimping ferrule is then crimped on to the conductor through the overlying outer insulating sleeve and the metal sleeve, both of which are also permanently deformed by such crimping, and the portion of the metal sleeve which extends beyond the crimping ferrule is crimped about the insulation of the conductor through the overlying outer insulating sleeve which is also permanently deformed by this crimping.
  • the metal sleeve serves to protect the conductor from bending stresses which would otherwise occur at the position where the conductor enters the crimping ferrule of the terminal.
  • the terminal can be made, for example by stamping and forming, from relatively thin stock material whereby the contact end thereof can be given desirable spring properties, the metal sleeve serving to increase the thickness of metal at the crimping ferrule of the terminal, thereby to ensure reliable crimping of the terminal to the conductor.
  • an electrical connector comprising an electrical terminal having a contact end and a crimping ferrule for connection to an electrical conductor, the crimping ferrule being received in a metal sleeve which extends beyond the end of the crimping ferrule in the direction away from the contact end of the terminal, the metal sleeve in turn being received in an outer sleeve of electrically insulating material, is characterised in that the metal sleeve is a seamless member having a relatively thick wall over the portion overlying the crimping ferrule, and a relatively thin wall over the portion extending beyond the end of the crimping ferrule.
  • the connector of this invention has the advantage that the two portions of this metal sleeve inherently have the necessary characteristics to enable the connector to be easily and reliably crimped to an insulated conductor, while allowing the terminal to be of any desired form, for example stamped and formed from resilient sheet metal.
  • Figure 1 shows a seamless circular cross-section metal sleeve 1 having a relatively thick wall portion 2 and a relatively thin wall portion 3.
  • Such a metal sleeve can be formed by conventional metal working techniques.
  • an intermediate portion 4 providing a funnel entry 5 from the portion 3 into the portion 2.
  • the intermediate portion 4 also provides a shoulder 6 facing into the portion 2.
  • the free end 7 of the portion 3 is flared outwardly to provide a funnel entry thereto.
  • FIG 2 shows the metal sleeve 1 received in an outer sleeve 8 of electrically insulating plastics material, which outer sleeve 8 extends beyond the free end 7 of the portion 3 of the sleeve 1.
  • Figure 3 shows the complete connector which includes an electrical terminal 9 having a receptacle contact end 10 for mating with a flat tab (not shown) and a crimping ferrule 11 of known form for connection to an electrical conductor, the crimping ferrule 11 being received in the portion 2 of the metal sleeve 1 with its insertion limited by the shoulder 6 therein.
  • the insulation 12 is stripped from a portion at the end of an insulated electrical conductor 13, and the end portion is then inserted into the free end of the outer sleeve 8 with the end of the conductor 13 being guided into the crimping ferrule 11 by the funnel entry 5 of the metal sleeve 1, which funnel entry 5 also serves to limit insertion of the conductor by engagement of the insulation 12 on the conductor with the funnel entry 5.
  • the crimping ferrule 11 is then crimped down on to the conductor 13 through the outer sleeve 8 and the portion 2 of the metal sleeve 1, and the portion 3 of the metal sleeve 1 can be crimped down on to the insulation 12 of the conductor through the outer sleeve 8, in known manner.
  • the relatively thick wall of the portion 2 of the metal sleeve 1 ensures reliable crimping of the connector 1 on to the conductor 13 even when the material from which the terminal 9 is made is relatively thin as may be necessary to ensure the necessary spring properties for the receptacle end 10 thereof, while the relatively thin wall of the portion 3 of the metal sleeve 1 allows for easy crimping of this portion on to the insulation 12 of the conductor. Further, the absence of a seam in the metal sleeve 1 ensures that the metal sleeve 1 will not relax after crimping as could occur if the metal sleeve 1 had a longitudinally extending open seam as found in some known connectors.
