  • Ring 3 is provided with a central hole whereas ring 4 carries a hollow extension 5 adapted to accommodate a conductor 6.
  • the plug-in member F which also carries an extension 8 adapted to receive a conductor 9, can bear, in the region of the hyperboloid throat, against the elementary wires 1, and deforms them resiliently. It will be understood that an electrical connection can thus be provided between conductors 6 and 9.
  • the machine intended to manufacture the above described socket comprises a support 10 having a cylindrical overhanging portion 11 adapted to receive socket 2 by sliding engagement of said socket on said portion 11 until the edge of socket 2 is in contact with an abutment shoulder 12 formed on said support
  • Cylindrical portion 11 is provided with rectilinear grooves 13, all inclined at the same angle with respect to the axis XX of said portion 11, extensions of said grooves being also provided in shoulder 12. These grooves serve to position the elementary wires 1, these wires being introduced on the side of said shoulder so as to project from the free end of cylindrical portion 11.
  • the machine comprises four elements aligned along axis XX, to wit, the above mentioned support 10, a push-piece 14, a casing 15 slidably surrounding support 10 and a casing 16 slidably supporting push-piece 14.
  • the machine also includes means for moving casings 15 and 16 axially with respect to each other.
  • casing 15 is fixed whereas casing 16 is movable, the above mentioned means being diagrammatically illustrated at 17 on FIG. 3 and being operated either manually or through any suitable power means.
  • Casing 15 is of tubular shape and a spring 18 is interposed between it and support 10 so as to urge toward the outside the cylindrical portion 11 of said support.
  • Casing 16 is also of tubular shape and a spring 19 is interposed between it and push-piece 14 so as to urge said push-piece toward support 10.
  • Spring 19 is weaker than spring 18 and its force may be adjusted by means of a screw 20.
  • Push-piece 14 has a cup-shaped end face 21 and cylindrical portion 11 has a flat end face 22, these two faces being adapted to pinch between them and to bend any wire portion projecting from oblique grooves 13.
  • casings 15 and 16 have respective end faces 23 and 24 adapted to cooperate together in shearing fashion, and disposed. radially beyond cylindrical surface 11 and, in the axial direction, approximately at the level of shoulder 12 when support 10 is pushed back toward the left in its limit position against the action of spring 18 (FIG. 5).
  • end faces 23 and 24 it is advantageous, as shown by FIGS. 3 to 5, to make the opposed ends of casings 15 and 16 such that they can engage -into each other with a radial play smaller than the diameter of wires 1.
  • an abutment is provided at some distance beyond the end face 22 of cylindrical portion 11 so as to limit'the distance to which a wire of any length introduced in a groove 13 can project beyond said end face 22, this abutment being operatively connected with casings 15 and 16 so that when said casings are moved toward each other, the abutment is automatically moved outwardly so asto bend the portion of the wirein contact therewith.
  • the above mentioned abutment consists of a lever 25 pivoted about an axis 26 substantially parallel to axis X-X and fixed with respect to casing 15, casing 16 carrying an inclined surface 27 against which lever 25 is applied by a spring (not shown) or the like.
  • Lever 25 is provided with the recess 25a, FIG. 2, having two walls at right angles to each other, one of these walls serving to stop the wire in the axial direction and the other-one to move said wire in the perpendicular direction when said lever 25 is rotated.
  • the machine includes at least one wire feeding device comprising a support 28 for a wire spool 29 (FIG. 2), a wire guide 30, preferably of tubular shape, leading to the inlet of a groove 13 and feeding means operated in synchronism with the movement of casings 15 and 16.
  • a feed device includes a first pair of rollers 31, a pair of driving rollers 32 and 33, one of these pairs of rollers 32 being actuated by a reciprocating rack 34 cooperating with the pinion 35 and a fre wheel 36.
  • Pinion 35 in mesh with the rack is given a ret; irocating rotation movement whereby the free wheel, and consequently roller 32, have an intermittent rotation always in the same direction so as intermittently to drive the feed wire A a distance equal to the length of an elementary wire 1 with its bent ends 1a and 1b.
  • support 10 includes a second cylindrical portion 37 of a diameter slightly smaller than the inner diameter of ring 3.
  • the right hand edge of ring 3 is brought to the level of shoulder 12 when support 10 is driven to its limit position in its casing and for this purpose it sufiices to provide casing 15 with a shoulder 38 to limit the displacements of ring 3 toward the left.
  • Ring 3 is engaged on the cylindrical portion 37 of support 10 and sleeve 2 is then slipped on the grooved cylindrical portion 11 of said support.
  • wire A is introduced into a groove 13 until it is stopped by lever (FIG. 2).
  • Casing 16 is then moved toward the left.
  • Oblique surface 27 first causes lever 25 to swing, which partly bends the free end of the wire (FIG. 3).
  • push-piece 14 pinches, between its end face 21 and the end face 22 of cylindrical portion 11, the partly bent end of the wire so as to give it the form preparatory to its wedging, as shown at 1b, the bearing pressure being limited by spring 19 (FIG. 4).
  • spring 18 yields, which causes support 10 to move rearwardly, the portion of wire A intended to form the end 1a being thus bent at right angles by contact with the edge of ring 3 and with the end face 23 of casing 15. Immediately after this, the end faces 24 and 23 of casings 16 and 15 respectively come into contact with the end In of the wire and cut it.
