Definitions

  • An electrical tab receptacle has a Channel-Shaped [58] Field of Search 339/223, 256 R 256 SP, receptacle portion having spring arms extending from 339/758 R 258 S 259 R 259 F 265 F one end of the base of the channel and overlying the u base, the arms being locked against outward movement by engagement with ears formed on the free edge of the channel sides.
  • Tab receptacles of many forms are known and a particularly successful form has a receptacle of channel form in which the sides are rolled over to provide springs for clamping a tab between edges of the springs and the base.
  • the performance of such tab receptacles is satisfactory in relation to contemporary requirements but owing to the metal content and to metal costs there is considerable demand for a product of comparable performance but reduced cost. Difficulty has been presented in maintaining the performance when the metal content has been reduced.
  • An electrical connector tab receptacle comprises a receptacle portion in the form of a channel having a base and two sides, a pair of arm folded up from an end of the channel and extending over the base to define together with the base and the sides of the channel a socket for a tab, the sides of the channel having free edges turned in over those sides of the arms distal from the base to resist movement of the arms away from the base by engagement with the sides of the inturned free edges with the arms.
  • the sides of the channel may be shorter than is required for rolled springs of the prior receptacles and thus the developed width of the receptacle is reduced.
  • the edges of the channel sides do not contact the tab, as in prior receptacles so that the quality of the edges is less critical.
  • receptacles according to the invention can be formed from metal strips of reduced width.
  • the receptacle is formed with a wire connecting section at the end of the channel formed with the arms and suitably the arms are formed by metal cut from the strip around the wire connecting section. This reduces the metal scrap by making use of metal normally wasted.
  • the arms suitable extend throughout the length of the channel and at their free ends are formed with ears projecting inwardly towards a middle of the base width, and turned up at leading inner portions away from the base to facilitate entry of a tab between the arms and the base.
  • FIG. 1 is a perspective view of a tab receptacle
  • FIG. 2 is a front end view of the receptacle of FIG. 1;
  • FIG. 3 is a side elevation of the receptacle
  • FIG. 4 is a plan view ofthe receptacle
  • FIG. 5 is a plan view of a blank cut from strip metal and partially formed in a stamping die, from which the terminal of FIGS. I to 4 is formed.
  • the tab receptacle of FIGS. l to 4 comprises a receptacle portion 1 and a wire-connecting portion 2 extending from a rear end of the receptacle portion l.
  • the wire-connecting portion 2 comprises a wire ferrule 3 and an insulation support ferrule 4 of U-section for crimping respectively about the wire core and the insulation ofa wire lead.
  • the receptacle portion 2 is of channel form having a base 5 and sides 6, the middle portion 7 of the base being elevated through a major portion of the width and length of the receptacle to define a platform 7 for engaging a tab.
  • a trough 8 At each side of the platform is a trough 8, and the platform is laterally slotted at 9.
  • a dimple 10 is centrally disposed behind the leading slot for engaging a latching aperture in a tab in known manner and the platform is suitably bowed widthwise in upwardly convex manner for appropriate spring engagement with the tab.
  • Two arms ll extend forwardly over the base 5 from the rear of the receptacle portion 1, one arm on each side of the wire connecting ferrule 3.
  • Sides ofa channel shaped transition section 12, between the ferrule 3 and the arms 11, extend into root portions of the arms II which are turned up from the base 5 and then forwardly to extend in generally parallel spaced relation above the base adjacent each side.
  • Free ends of the arms 11 are formed with ears 13 extending inwards over a middle of the base at a front of the receptacle.
  • the ears 13 are turned up, away from the base at their leading ends to facilitate tab entry, and as seen in FIG. 2 the ears slope inwardly and downwardly towards a middle of the base at a shallow angle.
  • the sides 6 have projecting upper edge ear portions 14 disposed rearwardly of the forward end, and rearwardly of the ears 14 the sides 6 slope down to the base forwardly of the rear ends of the arms 11.
  • Outer sides of the arms 11 have forward cut away portions so that the outer sides are clear of the sides 6, and the ears 14 are bent inwards to overlie the arms.
  • the arms 11 have an inner side profile 15 determined from the blank profile of the transition 12, wire ferrule 3 and insulation support ferrule 4.
  • the arms 11 are folded forwards over the receptacle base 5 as the transition and ferrule portions are formed into usection, and the sides 6 are folded up as the ears 14 are turned in progressively.
  • An electrical terminal tab receptacle comprising a receptacle portion in the form of a channel having a base and two sides, a pair of arms folded up from an end of the channel and extending over the base to define together with the base and the sides of the channel a socket for a tab, the sides of the channel having free edges turned in over those sides of the arms distal from the base to resist movement of the arms away from the base by engagement of the inturned free edges with the arms, and a wire-connecting portion extending from the receptacle portion at the end from which the arms are folded up; the arms being formed from excess metal removed from around the wire-connecting portion.
