Definitions

  • pin spacing is close, a typical example being 2.54mm where pin size is 0.635mm. It has been a problem to produce socket contacts by stamping and forming from sheet material using simple tooling of a size capable of accepting a square pin of a size such as 0.635mm square formed at a pitch of 2.54mm. The problem exists for other sizes and pitches.
  • the terminal portion may be an insulating displacement contact portion.
  • the invention further provides a stamped sheet of conductive material suitable for forming a series of contacts for use in a female connector, which stamped sheet provides an elongate attachment portion and a multiplicity of planar contact portions arranged side by side and attached to said attachment portion, each contact portion having a bridge portion, a pair of leg members extending from the bridge portion and being formable into a contact according to the invention, spacing of the contact portions corresponding to the pitch of pins of a male connector assembly with which the female connector is to mate, in use.
  • FIG. 1 illustrates a series of contacts 10 stamped from conducting sheet material 11.
  • Each contact 10 has an insulation displacement portion 12 although it will be appreciated that other types of terminal portion could be used.
  • Each contact 10 has a pair of leg members 13, 14 connected by a bridge portion 15.
  • FIG. 2 illustrates clearly how small the bridge portion becomes when in U-shape and the leg members are formed at this stage with respective outwardly cranked portions 16, 17 and inwardly cranked portions 18, 19 in the leg members 13, 14.
  • the leg members are formed with further outwardly cranked portions 20, 21 respectively at their free ends to allow ease of acceptance of a pin in use.
  • Figure 3 shows a contact 10 in position within a female connector block 30.
  • the block 30 has a passageway 31 therethrough, from one end of which emerges the terminal portion 12 and through the other end of which passes a pin 32.
  • the small dimension of the bridge portion 15 advantageously allows the passageway 31 to be of small dimension at that end thereof.
  • Ribs 33 and 34 extend into the passageway to lie inside free ends of the legs 13 and 14 to act as stops to prevent the leg members 13 and 14 approaching each other too closely at the reduced spacing region and thus causing difficulty of entry of the pin 32.
  • Forming contacts in this shape allows spacing of the contacts in the stamped sheet to be much closer than has hitherto been possible and enables socket contacts to be able to accept a standard pin size and yet still be stamped at 2.54mm pitch, yet requiring no complex metal forming to produce a workable configuration.
  • the fact that a simple operation is involved in formation of the leg shapes means that gold coating of selected parts can be carried out before formation while the contacts are all still held together. Since the socket pitch is the same as the pin pitch, each row of sockets can be inserted in a single operation rather than a double operation which has hitherto been necessary where sockets have been formed at double pin pitch.
