Definitions

  • This invention is related to apparatus for applying electrical connectors to insulated wire and comprises a novel combination of means for stripping a portion of the insulation from an insulated wire and for pressurecrimping connectors onto such wires.
  • An object of this invention is to'provide simple, compact, and inexpensive apparatus for pressure-crimping electrical connectors onto insulated wire which obviates the preliminary operation :of stripping away' a portion of the insulation, and/or the use of elaborate insulationstripping apparatus. 1 accomplish this object by providing a novel combination of insulation-stripping means and connector crimping dies such that an insulated wire inserted into the apparatus is automatically and almost simultaneously bared of insulation and the bared portion positioned in or operably near the wire-engaging portion 2,774,130 Patented Dec. 18, 1956 of a connector and then promptly crimped therein to form a secure connection.
  • Another object consist of providing means to perform these steps which is adapted to use in a standard press means of ordinary power and which further may be completely operated by a single operating cycle of such press means. Another object is to provide apparatus which meets all of the above Objects and which further is readily adaptable to different press means, different types and sizes of wire, and diiferent electrical connectors. Another object is to accomplish all of the above objects in a fashion. which cooperates with the automatic connector feeding .and severing means in automatic connector-applying machines.
  • a major objective resides inthe provision of a commercially feasible single-cycle stripper-cn'mper assembly containing a readily accessible wire gathering region and which will automatically and substantially instantaneously carryout a stripping and connector-applying operation whenever a wire is thrust into the wire gathering region.

  • Fig. 9 shows in side elevation a portion of a strip of connectors used in the-applicator.
  • Fig. 10 shows a wire after insertion into the tgire gathering region of the machine with a connector'applied toits stripped end'
  • FIG. 10 illustrate different aspects of. a preferred form of my novel applicatoran assembly which, driven by adequate press means, applies a connector to an insulated wire after first stripping the insulation from the wire to give a consistently high quality, low-unit-cost connection.

  • the crimper'; 24 shown is of that type having a deep channel-like'cavity.
  • the strips of connectors used in these and other auto-V matic machines generally consistof individual connectors formed from a'contin'uous strip of sheet r'netais'tock' commonly with sma'll' joining portions of the stock left to hold the connectors together.
  • the strip is fed the strip in the crimping area of the machine, between a .pair of opposed crimping dies, whereupon the end connector issevered from thestrip andc rim'ped onto" a wire.”
  • This automatic feeding, severing and crimpin'g of the 7 connectors permits the operator merelyto insert a wire a into aconnection-formingregion thus to start the power stroke of the machine;
  • the die means and ferrules portions may 1 intermittently tolocate repeatedly the end connector'of gether, as is shown'in Fig. 8.;

Extending laterally .outwardl from each 7,
  • the wire-stripper assembly 42 includes a wire stripper guide block 76 mounted on the upper surface of the bed 62, left and right wire stripper blades 78 and 80 slidably disposed in a stripper blade guideway 82 in the guide block 76, left and right stripper blade rocker arms 84 pivotally mounted to the guide block at 86, two follower rollers 88 on pivot pins 96 at the upper ends of rocker arms 84, and two stripper blade drive pins 92 extending from the lower end of arms 84 through short vertical slots 93 in blades 78 and 80.
  • rollers 88 and the upper portions of arms 84 are urged together by a spring 91 between the pivots 90 of the two rollers 38, thus urging apart the two drive pins 92 and stripper blades 78 and 80.
  • the rollers 88 are thus abutted against the lower corners of the ram 46 (see Figs. 3 and 4) when the ram is at rest; spring 91 pulls the rollers partly around the corners and spaces them apart slightly less than the width of the ram 46 so that the descent of the ram causes the two rollers 88 to move laterally apart as the ram 46 passes between them; therollers 88' ride on the lateral faces of the ram 46 as it completes its descent.
  • the rocker arms are thereby rotated about pivots 86 and the stripper blades 78 and 80 are driven together by drive pins 92.
  • the stripper blades 73 and 86 have semicircular conical insulation cutting and stripping edges 77 (Figs. 5 and 6) and mating a'ngularly disposed wire guiding surfaces 79. These wire guiding surfaces '79 are arranged so that those on each blade overlap those of the other blade. When the blades 78 and 80 are closed to their wire stripping position by the descent of the ram 46 the surfaces 79 guide the wire to be stripped into the desired position for proper stripping.
  • the angular guiding surfaces 79 center each wire between the insulation cutting and stripping surfaces 77 as the blades 78 and 80 are closed and minimize any likelihood that a strand of the metal conductor may be nicked or unintentionally removed during the stripping operation.
  • the electrical connections be of a quality higher than would be apt to result where even a single fine strand of the conductor had been removed during the stripping operation. This is because the crimping dies are designed to function, and do function, to extremely fine tolerances and where a strand has been removed from the conductor in the region of the crimp there is less metal present in the crimped region than the crimping assembly was adjusted for and accordingly a correspondingly inferior crimp results. Where quality connections are desired a metal-sensing unit may be employed in combination with the stripper.
  • Such a unit may operate on capacitance or magnetic flux principles whereby the presence of a strand of copper, for example, in the removal insulation sheath in passing through a region within the sensitivity of the unit will unbalance a circuit to stop the machine or give a visible or audible signal to an attendant indicating that the' conductor in the machine no longer has the proper cross section of conductive metal in the region of the'crimp.
  • a wire stop 94 is advantageously disposed behind the stripper blades 78 and 80 at a distance from their cutting edges 77 equal to the length of bare wire needed for a particular connection. With the inserted insulated wire 32 abutted against this stop a cycle of the press is started and the ram 46 begins todescend. Preferably this stop will be not shown on the drawing in order to simplify the show-- ing, but is mounted and related to the other parts shown in thesame way as is now ordinary in such sensitive switch controls in automatic machinery.
  • Theinitial descent of the ram 46 drives rollers 88 laterally outward and thus drives the insulation cutting edges 77 of the stripper ;blades 78 and 80 through the insulation sheath 33 of the wire 32 as shownin Fig. 7 and maintains these edges 77 abutted together and slidably abutted against the conductive wire core as rollers 88 roll on the descending ram' 46.
  • the wire clamp holder 56 is driven down by the ram 46. and guided longitudinally outwardly by follower pins 57 in cam slots 55, the initial descent also driving cam followers 63 and 65 of the wire clamp jaws 64 and 66 past the cam surfaces 71' of side earns 70 and 72, closing the jaws 64 and 66 to grip the wire 32 between their surfaces 59 and 61.
  • the gripped wire 32 is pulled forward by the cam surfaces 55 until it clears the stripper assembly, at'which point the cam followers 57 are approximately at the bend in surfaces 55.
  • the wire with its newly attached 5 of the connector strip 12 are 7' t pushed away from the strip by shear blade 34 in cooperation with shear plate 36 and slug plate 38 during the crimping operation and are ejected through an opening 95 in bed 62
  • the stripped portions of 'wire'insulation fall through the opening 96in guide block 76 and may ultimately be blown out of the applicator by such means as'an air jet (not: shown) timed to release a blast of air after'the metal-sensing: if any, and as the ram ascends.
