Abstract

1,255,319. Making electrical connections; angular bending; crimping; shearing. AMP Inc. 3 July, 1970 [31 July, 1969], No. 32361/70. Headings B3A, B3E, B3Q and B3W. In a method of connecting one or more leads to a terminal, a punch 46 and an anvil 48 are moved to cause the anvil to wrap portions of the terminal about the punch to form upstanding ears 12 and the terminal is advanced to position the ears between dies 58, 62 to crimp the ears to the lead or leads. A strip 1 of terminals is located on a guide plate 22 and is advanced step-by-step by means of spring loaded, pivoted feed fingers 32, 34, which have tips 36 engaging in apertures (4) in the strip, Fig. 1 (not shown). The feed fingers are resiliently connected to a piston-rod 28 for reciprocation therewith and drag plates 44 prevent backward movement of the strip 1 as the fingers are withdrawn. The punch 46 and die 58 are driven downwardly by a ram (53), Fig. 4 (not shown), after an operator has placed a bared end of a lead core between the ears 12. The plate 22 is also driven downwardly by the ram against a spring (24), Fig. 6 (not shown), thereby lowering a terminal on to the anvil 48 and shearing another terminal from the carrier strip (3), Fig. 1, between the working edge of a shear blade 66 and the die 62, prior to the crimping action of the dies. As the ram (53) rises, the leading terminal, which has been crimped to the leads is removed from the die 62 by the operator and the terminal strip 1 is advanced to place the leading terminal over the die 62.
