  • Figure 11 shows the position of the pre-insulated terminal and conductor positioned relative to the crimping assembly.
  • the device shown in the drawings is particularly useful in crimping an electrical connector of the type having an inner metal ferrule, surrounded by a plastic sheath, for example, the type shown in the patent to Watts, No. 2,410,321.
  • the assembly is placed in any well known crimping tool having a pair of jaws capable of being urged toward each other radially in relation to the connector to be crimped.
  • a preferred embodiment of the die assembly includes a first die member generally designated A and a second die member which is generally designated B.
  • a seating member 10 is removably securedv to the tool.
  • a supporting plate 12 is integral with the seating member 10, and at right angles thereto.
  • the plate 12 supports the insulation crimping means 14 (see Figure 5).
  • a connector receiving die 16 is integral with the die plate 12.
  • a pair of flare plates 18 and 18' are positioned one on either side of the plate 16 so that the surfaces of the notched portions 20 are coextensive with the conductor die surfaces 21.
  • the edges 22 of the flare plates seat on the supporting plate 12 so that the flare plates are parallel to the die 16.
  • the insulation crimping device 14 is generally plateshaped, as shown in Figure 5.
  • a vertical projection 26 formsflone side of insulation crimping die 28.
  • a graduated stepped portion 30 is provided in the opposite side of the crimping device 14 so that the projection 26 on each plate nests with the step 30 in the opposite plate to form a complete insulation crimping apparatus.
  • a slot 32 having steps 34, 36, 38, is fashioned in. the inner face of the plate 14 at the edge that seats on the supporting plate 12.
  • An adjustment assembly has a able longitudinally through the openings.
  • the pin 48 is adjustable longitudinally to position theassembly 40 so that one of the steps on the insulation crimping means will seat on the shoulder 42.
  • the insulation crimping means can be adjusted by changing the position of the assembly relative to the insulation crimping plate.
  • Slotted holes 44 in the plate 14 accommodate screws 46.
  • the slotted holes 44 are oversize to allow the plate 14 tobe moved toward or away from the supporting plate 12.
  • Corresponding screw holes 47 and 47' are provided in the flare plates 18 and 18' and die plate 16 respectively.
  • the screw holes 47 in the flare plate 18 are tapped to receive the threads on the outer surface of the screws.
  • the particular embodiment shown includes a cylindrical pin 48. and a rigidly secured rectangular member 42 at right angles thereto.
  • One of the steps 34, 36 or 38 seats on the rectangular member and the cylindrical member is used to longitudinally adjust the position of the assembly 40, thus adjusting the spacing of the insulation crimping members.
  • a spring 52 surrounds oneend of the pin 48. The spring is. disposed between the rectangular shoulder 42 and the die plate 16 (see Figures 6-8). Marks 51 on the cylindrical member indicate the setting of the assembly.
  • notched edges 20 are aligned with the conductor-crimping die 21.
  • the spring 52 is placed in the opening 23 of inner; flare plate 18, and one end of the pin 48 is placed longi tudinally through the spring 52.
  • the opening 56 in the die plate 16 permits the passage of the pin 48 but not the spring 52 ( Figure 2).
  • the spring 52 seats against the inner face of the die plate 16 while the pin 48 moves longitudinally through the opening 56 in the plate 16.
  • the inner flare plate 18 straddles the spring and pin at opening 23 (see Figures 2 and 5).
  • the opening 58 in the outer flare plate 18 is aligned with the openings 56 and 23 in the die plate and inner flare plate respectively, so that the cylindrical member 48 is mov-
  • the insulation crimping die 14 is seated on the supporting plate 12 with the slot 32 adjacent the r 3 inner flare plate 18 so that one 46 pass through the screw holes and are threaded into the flare'plate '18 to hold the' flare plates and insulation crimping assembly-in proper alignment 7 i g
  • the other indentingmember B is identical with the first indenting member A except for the shape of the conductor-crimping die.
  • the conductor-crimping dies shown in the drawings are merely an illustrative emb odiment of the preferred form. It is obvious that dies of various shapes may be employed.
  • the flare plates act as tapering means between the conductor crimping dies 21 and the insulation crimping dies 28. This prevents the formation of a sharp corner on the connector insulation at the jun'ction'of the conductor insulation and the conductor crimp, see Figure 9. Such a precaution reduces the possibility of tearing the insulation on the connector.
  • Figure 4 shows a portion of the flare plate 18' broken away as at 59. This permits the operator to view the relationship of the conductor crimping dies16 when the tool is in closed position to make sure that the dies have bottomed and that the crimp is complete.
  • Figures 6 to 8 show the insulation crimping assembly in three different adjustments.
  • Figure 6 shows the assembly with the maximum width A between the insulation crimping dies. In this position the shoulders 42 seat on steps 38.
  • Figure 7 shows the intermediate adjustment B with the shoulders 42 seated on steps 36.
  • Figure 8 shows an adjustment of the insulation crimping means with the minimum width C between the insulation crimping dies. The shoulders 42 are seated on the outermost steps 34.
  • the screws 46 are loosened to permit movement of the insulation crimping means 14 from the widest setting as shown in Figure 6 to the narrower setting of Figure 7.
  • the pin member 48 is moved longitudinally by the action of the spring 52. Whereas the plate 14 formerly seated on step 38 it now seats on step 36 and the plate 14 is moved in a direction away from the support plate 12.
  • the plate 14 of the other die may be shifted in a similar manner.
  • an intermediate adjustment may be made by only changing the setting of one of the insulation crimping dies. The screws are then tightened to hold the parts in place.
  • thedescribed embodiment provides an adjusting means which is accessible from the front of the'insert so that it; is not necessary to remove the insert assembly from the tool to make such an adjustment.
  • An assembly for crimping an electrical connector onto an insulated conductor comprising a pair of spaced supporting plates, aconductor-crimping means associated with each plate, an'adjustable, insulation-crimping means associated with each plate, said insulation-crimping means comprising a pair of rectangular members having comple'm'entary, spaced die surfaces, a graduated stepped slot in each of the members and an adjusting member slidably positioned between each. supporting plate and one of the steps in the slot of the respective member, whereby the spacing between the die surfaces on the insulation-crimping means maybe adjusted by moving either of the rectangular members relative to its supporting plate and its adjusting member.
  • a device as set forth in claim 1 including an outwardly extending pin on each adjusting member, each of said pins extending through an opening in its respective rectangular member, whereby the rectangular member may be adjusted by moving the pin.
  • the device as set forth in claim 3 including a releasable locking means holding each of the rectangular members in a predetermined position, and spring means resiliently urging the adjusting means toward one position.
