1446830 Making electrical leads; jointing by stamping; shearing AMP Inc 23 July 1974 [20 Aug 1973 and 12 Dec 1973 (2)] 32793/74 Headings B3A, B3Q and B3W To position the face ends of conduction wires in a predetermined spaced array at a work zone, the wires are placed on a template with their free ends extending beyond an end of the template to the work zone and held at a point adjacent an end of the template while the wires are forced into respective grooves in the template face extending from the work zone end, at which the grooves are in the predetermined spaced array, towards the opposite end. As shown, Fig. 1, a template 32, for use with wires projecting from a cable, has grooves 33 extending from a zone 132, where the wires are sheared and have terminals crimped to them, to a recess 38 for the cable which is held by a pivotable clamp 42. A carriage 48 running on wheels 56, 58 carries a roller 90 which is lowered on to the cable by a cylinder device 86 and is rocked by a driven eccentric and linkage 92- 100, while the carriage is moved along the template by a fluid cylinder 64, to force the wires into the grooves. The ends of the wires are sheared Fig. 4, (not shown), and the template is lowered to move the trimmed ends into the ferrules of convectors which are then crimped on the wires, Fig. 5 (not shown). A rigid plate may replace the roller 90. The template may have some sinuous grooves if wires are to be trimmed to different lengths. Wires fed from individual reels 200, Fig. 10, through a guide 206 are trimmed to the same length along shear line 212 and carried over template 32SP1/SP by a movable clamp 42SP1/SP. The template 421 is raised to engage the wires adjacent the clamp in grooves 33SP1/SP and a roller 90SP1/SP forces the rest of the wires into the grooves. The shear is actuated again and terminals are crimped to either end or as shown both ends. The crimping dies (140SP1/SP) include wire clamps (244), Fig. 13 (not shown), and means are provided for moving the shear out of the way as the crimping dies descend. In a further embodiment, Fig. 16, the carriage comprises a support 115 including arms 113, 114 carrying rollers 90b, 93b. The support is pivotable on a rod 116 reciprocated by a double acting hydraulic cylinder 64b and is pivoted to cause the rollers to force the wires into grooves 33b by a cam 118. The transverse rocking means of Fig. 1 may also be used. Extending through each groove 33b is a bore 110 through which a respective rod 156 can be pushed to form a loop in the wire. The stroke of the cylinder device 168 for actuating the rod(s) can be varied.
