Abstract
An apparatus is provided for widening the woven conductive sheath that Surround a shielded cable. The apparatus includes opposed punches that move into Contact with the exposed conductive sheath. Forces exerted by the punches are Sufficient to cause the extreme end of the exposed conductive sheath to be flared outwardly. The punches may be moved circumferentially around the wire for successive punching operations to achieve a uniform flaring. The punches also may be moved axially further away from the flared end to perform a second series of punches to flare the conductive sheath even further. The flared conductive sheath then can be folded over the insulating sheath.
Claims9
An apparatus for processing an end of a shielded cable, the shielded cable having an insulated wire, a conductive sheath covering the insulated wire and an insulating sheath covering the conductive sheath, a portion of the insulating sheath adjacent to the end of the shielded cable being removed to define an exposed portion of the conductive sheath, the apparatus comprising:
- at least one cable clamp for holding the shielded cable;
- a pair of punches spaced from the at least one cable clamp for punching the exposed portion of the conductive sheath of the shielded cable held by the at least one cable clamp;
- driving means for driving the punches sufficiently to punch the exposed portion of the conductive sheath without cutting through the conductive sheath and for withdrawing the punches away from the conductive sheath after the punching of the exposed portion of the conductive sheath;
- a punching control means for controlling the driving of the punches by the driving means;
- changing means for changing punching positions by relatively displacing the shielded cable and the punches substantially along at least one of a circumferential direction and a longitudinal direction of the shielded cable after the withdrawing of the punches by the driving means, the changing means comprising a sliding means for relatively displacing the punches and the conductive sheath so that the punching positions can be changed between an intermediate position of the exposed portion of the conductive sheath with respect to the longitudinal direction of the shielded cable and a base end of the exposed portion of the conductive sheath substantially adjacent to the insulating sheath;
- and
- a sliding control means for controlling the sliding means so as to punch the base end of the exposed portion of the conductive sheath after the punching of the intermediate position of the exposed portion of the conductive sheath.
An apparatus for processing an end of a shielded cable, the shielded cable having a wire, an insulation coating surrounding the wire, a conductive sheath covering the insulation coating and an insulating sheath covering the conductive sheath, a portion of the insulating sheath adjacent to the end of the shielded cable being removed to define an exposed portion of the conductive sheath, the apparatus comprising:
- at least one cable clamp for holding the shielded cable;
- a pair of punches spaced from the at least one cable clamp for punching the exposed portion of the conductive sheath of the shielded cable held by the at least one cable clamp;
- driving means for driving the punches sufficiently to punch the exposed portion of the conductive sheath without cutting through the conductive sheath and for withdrawing the punches away from the conductive sheath after the punching of the exposed portion of the conductive sheath;
- a punching control means for controlling the driving of the punches by the driving means;
- changing means for changing punching positions by relatively displacing the shielded cable and the punches substantially along at least one of a circumferential direction and a longitudinal direction of the shielded cable after the withdrawing of the punches by the driving means;
- a suction nozzle to be fitted on the end of the shielded cable held by the at least one cable clamp,
- a peeling unit guided by the suction nozzle for cutting the insulation coating at the end of the shielded cable by at least one pair of substantially opposed peeling blades, and
- a sliding mechanism for relatively moving the peeling unit and the at least one cable clamp substantially along the longitudinal direction of the shielded cable,
- wherein a piece of the insulation coating of the shielded cable is peeled off and collected by the suction nozzle.
