Definitions

  • This invention relates to an electrical contact member, and particularly to a female electrical contact member for mating with a male contact pin.
  • a female electrical contact member comprising a substantially U-shaped body portion from the sides of which extend a pair of opposed resilient cantilever contact arms between which a male contact pin can be received.
  • EP-A1-0008221 It has been proposed in EP-A1-0008221 to provide an electrical contact member comprising a substantially U-shaped body portion from the sides of which extend a pair of opposed resilient cantilever contact arms between which a male contact pin can be received.
  • US-A-3 450 849 discloses an electrical contact member stamped and formed in one piece of metal and comprising a body portion from opposite sides of which extend a pair of opposed resilient cantilever contact arms between which a male contact pin can be received, a third support arm extending from the body portion between the contact arms the contact arms being resiliently biased towards each other against the support arm and held apart by the support arm at a position between their roots and free ends.
  • the invention is characterised in that the support arm has been deformed from an initial position in which a free end of the support arm is spaced from and aligned between the contact arms to a final position in which the free end of the support arm is received between the contact arms in engagement therewith thereby to maintain the free ends of the contact arms laterally spaced apart, the contact arms having been flexed apart from an initial condition, corresponding to the initial position of the support arm in which the free ends of the contact arms are adjacent each other, to a final condition, corresponding to the final position of the support arm, in which the free ends of the contact arms are spaced apart with the contact arms receiving the free end of the support arm between them.
  • the contact arms can initially be bent to be in contact with each other, that is to a position which, if they were to be left in such position, would make insertion of a male contact pin very difficult, the support arm then being located between the contact arms to hold them apart at a distance making insertion of the male contact pin relatively easy.
  • the contact arms are then resiliently biased against the support arm but when a male contact pin is inserted they are further deflected apart and out of contact with the support arm, the contact force with which the contact arms then grip the male contact pin deriving not only from the further deflection of the contact arms occurring on insertion of the male contact pin but also from the force with which the contact arms were resiliently biased against the support arms.
  • the contact member shown in Figures 1 to 5 is stamped and formed from sheet metal integrally joined to a plurality of similar contact members in strip form, by means of carrier strips 100, in known manner.
  • the contact member comprises a contact portion 1 and a wire connection 2 which is of known insulation displacement form and which will not therefore be described in detail.
  • the contact portion 1 comprises a substantially U-shaped body portion 3 from the sides of which extend a pair of opposed resilient cantilever contact arms 4 and 5 each indented near its free end to provide a contact projection 6 directed towards that of the other contact arm.
  • Each contact arm 4 or 5 is formed with a longitudinally extending, inwardly directed indentation 7 which serves to stiffen the contact arm across its junction with the body portion 3.
  • Extending from the bight of the body portion 3 is a third, support arm 8 which projects in the same direction as the contact arms 4 and 5, the free end of the support arm 8 being curved towards the contact arms 4 and 5.
  • the stamped blank from which the contact member is formed is initially formed such that the contact projections 6 on the contact arms 4 and 5 are in contact with each other ( Figure 2), the support arm 8 not being positioned between the contact arms 4 and 5 ( Figure 1).
  • the contact arms 4 and 5 are then urged apart and the support arm 8 then moved to be positioned between them ( Figures 3 and 4).
  • the contact arms 4 and 5 resiliently engage the support arm 8 which then serves to hold their contact projections 6 apart ( Figure 4).
  • the contact member is then ready for use.
  • the support arm 8 holds the contact projections 6 spaced by a distance less than the relevant dimension of a male contact pin 200 to be mated with the contact member, such that on insertion of the pin 200 between the contact projections 6 the contact arms 4 and 5 are urged out of engagement with the support arm 8 and remain thus while the pin 200 is mated with the contact member.
