Definitions

  • This invention relates to hand tools for inserting and extracting taper pin electrical connectors from receptacles.
  • Taper pin connectors are widely used for making permanent and semi-permanent electrical connections and are particularly useful for connecting relatively small wires. ylt has been found that for best results, connectors of this type should be inserted by the application of an impact blow of predetermined magnitude and that if a pin has been properly inserted, the integrity of the connection can be determined by applying a pull test to the pin. For example, it has been found that one type of taper pin requires a force of 25 toy 30 pounds for extraction if the pin is properly inserted into its receptacle. With this particular pin, the effectiveness of the insertion can be established by applying a pull test of about 10 pounds to the pin.
  • lt is, accordingly, an object of the present inventionto provide a tool for extracting taper pin electrical connectors from their receptacles.
  • lt is a further object to provide a single tool having means for inserting taper pins into receptacles, means for extracting taper pins from receptacles, and embodying a compulsory pull test feature so that each pin inserted with the tool must be pull tested by the operator.
  • a preferred embodiment comprising a rod, a spring loadable hammer for delivering an inserting blow to the end of the rod, means for gripping the pin on the end of the rod and a detent means for maintaining the gripping means in contact with the pin.
  • the preferred embodiment provides also a pin extracting device comprising a collet in surrounding relationship to the rod and having an extension which projects to a point adjacent the rod tip. This collet is normally maintained in a retracted position ate , Patented Mar, 28, ll
  • a cam is provided on the collet which acts between the rod and the collet so that upon actuation of this cam, the collet extension is moved relatively beyond the tip of the rod.
  • the cam is thereafter actuated to cause the extension to move relatively beyond the rod tip. As it does so, it comes to rest against the receptacle in which the taper pin is positioned and upon further movement of the cam, the rod itself moves relatively away from the receptacle and carries with it the taper pin.
  • Figure 1 is a perspective view of a preferred embodimentg.
  • Figure 2 is a sectional view of the embodiment of Figure l;
  • Figure 3 is a sectional view of the end of the tool showing details of the pin extracting features of the tool
  • Figure 4 is a view similar to Figure 3 showing the relative positions of the parts during a pin extracting operation
  • Figures 5 and 6 are views similar to Figures 3 and 4 respectively but with parts broken away;
  • Figure 7 is a view taken along the line '7 7 of Figure 5.
  • the preferred embodiment comprises a tool barrel 2 and a handle 3, the barrel 2 being composed of three separate sections, 4, 6 and 8.
  • the center section -6 has a reduced diameter cylindrical extension lil ⁇ and threadedly receives the lower end section 4 and the upper end section 8.
  • End section 4 comprises a simple cylindrical sleeve which is in concentric relationship to extension 10 so that a recess 7 left between the outer surface of section 10 and the inner surface of end section 4.
  • the upper end section 8 projects upwardly for a substantial distance into handle 3 as shown at 9 and is axially hollow for substantially all of its length.
  • extension lil The lower end of extension lil is provided with a bushing 12 which slidably supports ⁇ a rod 14, this rod being supported additionally by a nut 16 threaded into the bore of the central section 6.
  • Rod 14 has an axial slot i8 extending for substantially its entire length and has a cavity 20 at its lower end for the accommodation of the taper pin.
  • the taper pin T is held by means of-a slot or groove 22 at the tip of the rod and a transverse groove 24 into which the collar of the taper pin extends.
  • an oblique recess or opening 26 is provided in the rod 14 adjacent cavity 2@ for the accommodation of the wire to which the pin is attached.
  • the upper end of rod 114 has a stop nut 2S threaded thereon which bears against the surface of an internal constriction or wall 29 in the bore of end section 8.
  • the upper end of the rod projects partly into a reduced diameter opening 30 in this wall to permit delivery of an impact blow as described below.
  • a key 32 is slidably received in groove 1S and provides ears 36, 33 intermediate its ends.
  • Ear 3e extends into the bore of barrel section 6 between the upper end of bushing 12. and the lower face of a slidable bushing d2.
  • This slidable bushing is normally biased downwardly by a coil spring 44 which acts between the lower surface of nut 16 and the upper face of the bushing 42.
  • the lower face of the bushing is bevelled as shown and bears against a plurality of ball bearings di) (only one of these ball bearings being shown in the drawing).
  • bearings extend into a relatively shallow circumferential groove 4l in rod i4 and are urged against bushing -12 by spring 4d so that relative movement between the rod and the barrel 2 is not possible until these bearings are cammed outwardly.
  • the end of key 32 extends over cavity 26 and holds the taper pin in this cavity when the parts are in the positions shown in Figure 2.
  • the tool handle 3 and the portion 9 of end section 8 may contain any suitable type of spring-loadable impact hammer.
  • the hammer 45 is received within the bore of the cylindrical portion 9 of the tool barrel and has a projection 48 on its lower face which is adapted to enter reduced diameter bore 39.
  • a pin Sn extends through a slot l in the hammer and also through an oversized slot in the upper portion 9 of the tool barrel and is mounted at its ends in the handle 3 thereby to permit relative motion between the hammer, the handle, and the end 9 of the barrel.
  • upper end of the hammer is axially bored for the reception of a coil spring 52 which bears against the face of a screw 54 in the cap piece 56 on the upper end of the tool handle.
  • An additional spring 58 surrounds the hammer and is imposed between the uppe-r end 59 of'barrel portion 9 and the face of the cap piece.
  • a spring biased detent dil in the hammer projects through a circular opening in the tool barrel extension and into a circumferential groove 612 on the inside surface of the tool handle. This groove tapers inwardly as shown at 63 to cam the detent inwardly as the handle is moved downwardly in the drawing.
  • a slot 65 in the barrel extension which slot opens into circular opening 51 and which is sufficiently wide to receive the reduced diameter end of the detent.
  • the taper pin extracting device on the tool comprises collet I6 which surrounds the rod and has an extension 72 projecting therefrom along the rod.
  • the collet is biased upwardly by means of a spring Si! which acts between a colla-r 73 integral with rod 14 and an extension 74 on the collet.
  • This extension which comprises a cylindrical sleeve, is received in the circumferential recess defined by the sleeve d and the lower end 1d of the intermediate section of the tool barrel.
  • a salient advantage of the invention is that the technician can be provided with a single tool capable of performing all of the necessary operations for the making of taper pin connections and the extraction device on the end of the tool in no way eiiects the normal usage of the tool for insertion and pull testing although this extraction device is immediately available when needed.
  • a tool for taper pin electrical connectors comprising, a rod, means on one end of said rod for holding a taper pin, a tool barrel in surrounding relationship to said rod, with said one end extending beyond said tool barrel, means within said tool barrel for delivering an impact blow to the opposite end of said rod, a collet in surrounding relationship to said rod adjacent said one end, an extension on said collet extending along said rod, resilient means acting between said rod and said collet and normally urging said collet towards said barrel, and meansV in said collet for moving said collet relatively away from said tool barrel against the force of said resilient means thereby to move said extension beyond said one end and to permit removal of a taper pin from a receptacle by relative movement of said rod away from the receptacle.
