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.
  • an electrical contact member as set out above is characterised in that the contact arms are inherently resiliently biassed towards each other and supported at a position between their roots and their free ends.
  • Either the contact arms can be resiliently biassed directly against each other at the position of support, or the contact member can include a third, support arm extending from the body portion between the contact arms, the contact arms being resiliently biassed against the support arm.
  • the contact member of this invention has the advantages that it provides a relatively high contact force on a male contact pin mated therewith while still allowing relatively easy insertion of the male contact pin.
  • the contact arms are initially bent so as to be inherently resiliently biassed against each other while leaving their free ends spaced apart at a distance making insertion of the male contact pin relatively easy.
  • a male contact pin is inserted between the free ends of the contact arms they are deflected apart and out of contact with each other, the contact force with which the contact arms then grip the male contact pin deriving not only from the 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 biassed against each other.
  • 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 biassed 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 biassed against the support arm.
  • 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 portion 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.
  • the stamped blank from which the contact member is formed is initially formed such that the contact arms 4 and 5 each extend at a certain angle to the plane of the bight 18 and side walls of the body portion 3, this certain angle being such that when the U-shaped body portion 3 is subsequently formed the contact arms 4 and 5 become inherently resiliently biassed against each other at a position 10 between their roots 9 and their free ends 6 as shown in Figure 9, the contact arms 4 and 5 being shaped such that their contact projections 6 are then spaced apart for insertion of a male contact pin (200 in Figure 10) therebetween.
  • the contact arms 4 and 5 then each extend at an angle which is less than the initial certain angle to the plane of the associated side wall of the body portion 3.
  • the contact member is then ready for use.
  • the contact projections 6 are initially 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 each other and remain thus while the pin 200 is mated with the contact member.
