<p>1,230,068. Shearing. AMP Inc. 6 Oct., 1969 [29 Oct., 1968], No. 48977/69. Addition to 1,211,485. Heading B3W. [Also in Division H2] The cable preparation procedure of the parent Specification, prior to the connection to a terminal, is modified in that the outer shielding material is flared by moving the dielectric laterally of its axis to flare the shielding material, before a portion of the dielectric is removed to expose the inner conductor, so that cables with fine or fragile inner conductors can be prepared. The spindle 84 carrying blades 117, 118, 351 on arms 119, 124, 349 is rotated continuously at about 800 r.p.m., and has a mounting platform 110 and anvil 114 to support the cable. Blade 351 cuts through the sheath and the shielding of the cable, followed by blade 118 which cuts only the sheath. The spindle 84 carrying all the blades is then retracted pulling the cut portions off the cable. A pair of gripping fingers (414, Fig. 4) which also rotate with the spindle then grip the dielectric eccentrically, the twirling of the dielectric flaring the end of the shield. The fingers 414 are then relaxed and the spindle 84 advances again to position blade 117 over the dielectric and cut it (Fig. 7). The cutting sequences are controlled by axial movement of collar 127 relative to the spindle 84, the collar carrying a cam follower 125 which runs on camming surfaces formed on the backs of the arms 119, 124, 349.</p> |
