  • a center contact arm 20 is provided at the base of the contact for extension through a PC board to the like and may consist of any known contact shape.
  • a first bifurcated portion 22 provides a wire contact which is in longitudinal alignment with the center contact arm 20 and a pair of symmetrically designed insulation contacts indicated generally at 24 and 26 are provided at opposed sides of the wire contact 22.
  • the insulation contacts 24 and 26 are respectively bent in opposed directions so as to be in alignment with wire contact 22, as shown in FIGS. 2 and 3.
  • the contact 12 when in the fully formed condition, as shown in FIGS. 2 and 3, is capable of providing good structuralintegrity due to the generally S-shaped construction, and can be used with non-insulated wire, insulated wire, ribbon type cable and the like.
  • the bifurcated wire contact 22 is provided with a contact wedge slot 28 having a width of such dimension that the wire contact will cut through any insulation about the wire and will compress opposite sides of the wire as the insu lated wire is forcibly inserted into the wedge slot.
  • the wire is compressed to an oval shape and the opposite sides thereof are wiped upon forcible insertion in the slot, to provide wiping of the wire surfaces and the slot surfaces for good electrical conductivity, as shown most particularly in FIG. 5.
  • outer sides 30 of the contact act as opposed resilient cantilever beams which, upon forcible insertion of the wire between the beams, provide resilient cantilever compression on the inserted wire to assure forcible contact with the wire for good conductivity.
  • the outer sides 30 of the wire contact are substantially straight so as to provide strength to the wire contact while the contact retains a generally resilient nature.
  • the knife edge 16 provided on each of the bifurcated portions of the wire contact enable the contact to cut through the insulation on ribbon type cable when the contact is used in conjunction therewith.
  • the knife edge 16 is outwardly angled as at 32 so as to provide a notch capable of easily receiving an insulated wire and for funneling the wire into the slot 28.
  • Insulation contacts 24 and 26 are each bifurcated and provided with central grooves or slots 34 and 36, respectively, which are in alignment with contact wedge slot 28 such that a wire received in the center slot would be likewise received in the grooves or slots 34 and 36 with the wire in a straight position such that strain relief and resistance to pull-out would be provided therefor.
  • the width of slots 34'and 36 is dimensioned such that a wire placed along the slots would be supported by its insulation to adequately provide strain relief and resist pull-out of the wire from the contact 22 as shown in FIG. 4.
  • Each of the bifurcated portions of the insulation support contacts is provided with an entrance angle portion 38 and an outside angle portion 40 meeting at a point 42 such that when used with wires in side-by-side relationship in an insulation covering in a ribbon type cable 43 or the like, instead of individual insulation covered wires, the piercing points 42 easily cut through the insulating portions 45 of the ribbon type cable and the entrance angles funnel the conductor into the insulating support grooves 34 and 36. As shown in FIG. 2, the piercing points 42 are on both sides of and extend above the central contact slot 32. As the ribbon type cable is forced into contact with the terminal 26, the points 42 will initially engage and then cut through the insulating portions 45, thereby dividing out a single wire from the insulating portions 45.
  • Locating tabs 44 and 46 are integrally formed and downwardly extended at each insulation contact 24 and 26, respectively, and are provided with a flat base portion for engagement with a PC board or the like. As shown in FIG. 4, the individual wire 47 in the grooves 34 and 36 is in compression but in less compression than in the slot 28.
  • the unique construction of the contact of the present invention provides good structural integrity due to the generally S-shape, and provides strain relief for a wire held by and anchored in the insulation contacts 34 and 36 while the wire is in good electrical contact with the contact wedge slot 28. Since good structural integrity is provided in the construction of the contact of the present invention, and since the wire is effectively anchored to the contact support grooves 34 and 36 on either side of the contact slot 28, resistance to pull-out of the wire from either side of the contact slot 28 is assured, and there is no necessity for providing a separate housing or support for the contact, as has been generally necessitated by the prior art devices.
  • triple wedge contacts of the present invention are typically inserted within through holes in a PC board with their locating tabs 44 and 46 in appropriate position such that the tabs abut the PC board thereby positioning the contacts at a predetermined height above the board.
  • the unique tool disclosed therein comprises a housing 48 which has a handle 50 integral therewith and a hand grip 52 which is pivotally mounted with respect to the housing 48 and handle 50 by means of pivot pin 54.
  • An actuating extension 56 is integrally fixed upon hand grip 52, one surface of extension 56 being adjustably abutted by a set screw 58 which determines the extent of travel of extension 56 and hand grip 52 in one direction.
  • Defined within housing 48 is a first cylindrical bore 60 and a second reduced cylindrical bore 62 for receiving a cylindrical ram 64 therein.
  • the rear terminal portion of ram 64 comprises a flanged section 66 which abuts another surface of actuating extension 56.
  • a coil compression spring 68 Surrounding cylindrical ram 64 and seated within the larger bore 60 is a coil compression spring 68, the ends of spring 68 abutting flange portion 66 and the reduced diameter portion of bore 60 and 62, spring 68 thereby maintaining ram 64 in its retracted mode upon the release of hand grip 52 as shown in FIG. 6.
  • the forward operative portion of the tool includes a pusher member 70, a contact holder'72, and a wire cutter 74.
  • Contact holder 72 is fixed relative to housing 48 via an internally threaded sleeve 76. Referring more particularly to FIGS. 7 and 8, it is seen that the forward portion of contact holder 72 comprises a pair of resilient holding fingers 78.
  • Contact holder 72 additionally comprises a first bore having a diameter sufficient for retaining the larger diameter of the ram 64.
  • Ram 64 further comprises a flattened area 82 for cooperation with a retaining pin 84 situated within the bore 80, pin 84 thereby preventing any rotation of ram 64 relative to bore 80.
  • Contact holder 72 additionally comprises second, third and fourth cylindrical bores 86, 88 and 90, of consecutively diminished diameters, the third cylindrical bore 88 further containing a generally ovoid aperture 92 for providing flexures 94 which in turn resiliently bias holding fingers 78. Holding fingers 78 define therebetween a wire receiving slot 96.
  • a retaining pin 98 laterally disposed within the forward portion of ram 64 secures a pusher element 100 within an aperture formed within such forward portion, pusher element 100 further containing an anvil member 110.
  • a wire 112 is disclosed as being positioned within wire receiving slot 96 in abutting relationship with the forward portion of anvil which is in its fully retracted mode.
  • extension member 56 pivots around pivot pin 54 thereby abuttingflange portion 66 of ram 64 so as to longitudinally move ram 64 against the action of coil spring 68. Movement of ram 64 in turn causes longitudinal movement of anvil member 1110, thus advancing wire 112 from its position disclosed in FIG. 8 to that disclosed in FIG. 9. Simultaneously with the aforementioned action, a pair of ram cam surfaces 116 abuts the upper portion of slot 96 so as to laterally spread the resilient fingers 78, thus releasing the tool from the contact 12.
  • Wire cutter 74 consists of a tubular sleeve having a first bore portion 118 for surroundingly engaging an outer wall protion 120 of contact holder 72, the sleeve being additionally provided with a pair of slots 112 which respectively receive the pair of pins 124 which are fixed within outer wall I such that the wire cutter 74 may be rotated relative to contact holder 72.
  • Extending downwardly from the sleeve of wire cutter 74 is a pair of cutting members 126 and 128, the cutting members being identical in construction but oppositely faced.
  • Each of the cutting members 126 and 128 includes a pair of cutting edges 130 and 132 such that by rotating the member 74 either clockwise or counterclockwise, one side of the wire can be selectively aligned with the cutting edges.
  • the wire would first be cut, as shown in FIG. 10, and would secondly be inserted within the grooves of the contact.
  • the tool thus is utilized to bridge between and electrically connect a wire from point-to-point locations defined by two or more spaced contacts 12 mounted on a PC board without a need for severing the wire.
  • the wire may be connected to a selected contact 12 on the PC board and then severed, thus ending the wire at its connection to the selected contact 12.
  • the slot portions 28 and 34 and 36 may be tapered in width such that a wire being progressively forced toward the bottom of the slot becomes progressively compressed in narrower widths of the tapered slots;
  • the slot of said central contact portion being adapted to slice through the insulation of an insulation covered wire wedgingly received in said slot to establish electrical connection between the insulation covered wire and the edges of said central contact portion along the slot thereof,
  • each of said openings being located outwardly above the central contact portion of said S-shaped portion.
  • An electrical terminal adapted for insertion in a printed circuit board comprising:
  • said first contact portion having a slot therein communicating with one side of said contact portion
  • each said additional contact portion having a slot therein extending from one side thereof, whereby an insulation covered wire may be anchored and supported by its insulation within the slot of each said additional contact portion to resist pull-out of the wire from the first contact portion, and
  • each said outer contact portion having a depending projecting tab in engagement on said printed circuit board for location of said contact against said printed circuit board.
  • each said strain relief members having a slot therein, the slots of said strain relief members being in alignment with each other,
  • said wire receiving contact element having a slot therein in alignment with each slot of said strain relief members
  • the slot of said wire receiving contact element being of lesser width than either slot of said strain relief members, whereby a relatively straight length of insulation covered wire may be wedgingly received in the aligned slots, with the wire receiving contact element adapted for slicing through the insulation for electrical contact with the wire, and with the strain relief members anchoring the insulation covered wire on either side of said wire receiving contact element;
  • said wire receiving contact element being integral with each said strain relief member
  • each said wire receiving strain relief members includes a projecting portion which projects above said wire receiving contact member
  • each said enlarged entrance opening portion communicating with said slot of a corresponding strain relief member.
