  • a pair of bifurcated sub-groove engaging fingers 354 and 356 are disposed at the inward surface of key 344, the fingers being of a thickness less than that of key 344 and adapted to engage an adjacent pair of sub-grooves 339. In the embodiment illustrated in FIG.
  • engaging fingers 354 and 356 are substantially at right angles to one another, intersecting the mid-point of key 344 in a generally arcuate surface 355. Spaced outwardly from engaging fingers 354 and 356 are a pair of cone-shaped indentions 358 and 360 and a slot 362, the slot 362 straddling one of the connector bolts 328.
  • Key 344 is biased against the lower face of slot 346 by a pair of ball members 364 and 366 loaded by a pair of coil springs or the like 365 and 367, springs 365 and 367 being disposed in a pair of axially extending bores 368 and 370 between slot 346 and an outer face of the housing member 312.
  • the upper portion of the bores 368 and 370 being closed by counterbore portions 372 and 374 in which are disposed a pair of threaded set screws 376 and 378.
  • turret head assembly 310 is detachably connected to crimping tool 12 in the same manner previously described with respect to the first and second embodiments.
  • the upper face of turret head 316 is suitably inscribed to designate the contact sizes, etc. and the housing member includes an inscribed indexing line 380.
  • the axial adjustment for the desired contact is first selected by rotating the turret head relative to the housing member until the inscribed size designation between adjacent members generally straddles indexing line 380. In this position it will be noted that the indexing grooves are generally normal to indexing line 380 and turret head 316 is free to be moved axially due to disengagement of the fingers of key 344 with sub-grooves 339.
  • Indexing grooves 342 are again preferably color coded and the desired groove is located flush with the upper face of housing member 312.
  • turret head 316 is rotated until the proper inscribed size or diameter is opposite indexing line 380.
  • the engaging fingers 354 and 356 will engage the adjacent pair of sub-grooves 339 and snap therein.
  • the operator can check whether the outer circular face 348 of key member 344 is flush with the outer annular surface of housing member 312. The electrical contact may now be crimped in an indentical manner described for the previous embodiments.
  • springs 365 and 367, and spring 268 of the second embodiment are chosen based on the same criteria as are springs 120 in the first embodiment and as described therewith.
  • a turret head assembly for locating an electrical contact or the like relative to the crimping zone defined by the indentor means of a crimping tool, the assembly comprising:
  • housing means adapted to be connected to the crimping tool
  • first means defining at least two spaced circumferential grooves in an outer surface of said locating head means, said grooves being spaced different distances from the crimping zone;
  • locating means difining at least two locating apertures on said locating head means for receiving and locating the electrical contacts;
  • actuating means for positioning one of said locating aperatures in coaxial alignment with the crimping zone, and being respectively cooperable with one of said grooves for locating said locating head means a first distance from the crimping zone and with another of said grooves for locating said locating head means a different distance from the crimping zone.
  • each of said circumferential grooves consists of a set of at least segmental shaped grooves lying in a common plane.
  • said actuating means comprises a key having a bifuricated end portion adapted to selectively engage a pair of said segmental shaped grooves.
  • each of said circumferential grooves is continuous and extends about the entire circumference of said locating head means.
  • each of said circumferential grooves extends only partially around the circumference of said locating head means.
  • each said circumferential groove is generally segment shaped.
  • a turret head assembly for locating an electrical contact or the like relative to the crimping zone defined by the indentor means of a crimping tool, the assembly comprising:
  • housing means adapted to be connected to the crimping tool
  • locating head means supported by said housing means and movable longitudinally parallel to the axis of the crimping zone, said locating head means defining at least one locating aperture for receiving and locating an electrical contact;
  • first means defining a plurality of axially spaced indicia on an outer surface of said locating head means, the position of said indicia with respect to said housing means indicating the axial position of said locating aperture relative to the crimping zone; and second means for locating said locating head means at different axial distances from the crimping zone.
  • a turret head assembly for locating an electrical contact or the like relative to the crimping zone defined by the indentor means of a crimping tool, the assembly comprising:
  • housing means adapted to be connected to the crimping tool
  • locating means defining at least one locating aperture on said turret head means for receiving and locating an electrical contact
  • said recesses being spaced different predetermined distances from the crimping zone, said distances corresponding in position to the desired axial locations of the located contacts with respect to the crimping zone during crimping and corresponding in number to the number of such locations;
  • actuating means selectively engageable with one of said recesses for positioning said locating head means a first predetermined distance from the crimping zone and with another of said recesses for locating said locating head means a different predetermined distance from the crimping zone.
  • a turret head assembly for locating an electrical contact or the like relative to the crimping zone defined by the indentor means of a crimping tool, the assembly comprising:
  • housing means adapted to be connected to the crimping tool
  • first means defining at least two pairs of circumferential grooves in an outer surface of said locating head means, said pairs of grooves being circumferentially spaced and each spaced a different distance from the crimping zone, the grooves of each pair being circumferentially spaced;
  • locating means defining at least two locating apertures on said locating head means for receiving and locating the electrical contacts
  • actuating means respectively cooperable with one of said pairs of grooves for positioning said locating head means a first distance from the crimping zone with one of said locating apertures in coaxial alignment with the crimping zone and with another of said pair's of grooves for positioning said locating head means a different distance from the crimping zone with the other of said locating apertures in coaxial alignment with the crimping zone.
  • said actuating means comprises a pair of spaced fingers, end portions of which are respectively engageable within the grooves of a pair of said grooves, said end portions being selectively engageable with the ungrooved portions of said outer surface disposed circumferentially between said grooves for permitting said locating head means to be adjusted to different axial positions.
