20100313402 | TOOL FOR PROCESSING LIGHT WAVE CONDUCTORS - A hand tool is operable to crimp a tubular metal contact member concentrically about the stripped end portion of an insulated fiber optic light-wave conductor in spaced relation to the free end extremity thereof. A tensioning arrangement tensions the excess portion of the conductor that extends beyond the contact member, whereupon a cutting device engages the tensioned portion of the conductor to sever cleanly the excess extremity from the conductor. The tensioning arrangement serves to deflect the conductor excess end portion obliquely outwardly relative to the longitudinal axis of the conductor. Tensioning is achieved by a deflecting disk positioned normal to the longitudinal axis of the light-wave conductor, or by a guide bore contained in a conductor guide device attached to the tool body. Preferably, two contact members are simultaneously crimped on a pair of conductors, and the excess ends of the conductors are simultaneously tensioned and severed. | 12-16-2010 |
