Abstract: A tool that seats and cuts multiple wires inserted into terminals of a multi-terminal jack includes a support housing for a linearly translatable, and removable carrier. The carrier fixedly retains one of a blade head and a jack, and slidably retains the other of the jack and the blade head, in such a manner that the jack is maintained in precision alignment with the blade head as the carrier is linearly translated within the support housing. A carrier translation control mechanism is coupled to the support housing in a manner that pushes and thereby linearly translates the carrier, so as to bring the blades of the translated blade head into precise stuffing and cutting engagement with the wires in the jack.

Abstract: A battery-powered impact wire insertion tool that employs an electric motor to implement the impacting function. The electric motor is provided with suitable gearing that reduces its speed but increases its torque. An activator mechanism is employed to convert multiple revolutions of the motor shaft into a stored compressive force that after a predetermined number of shaft revolutions is triggered to release the compressive force to drive a hammer against an insertion blade mounted in the tool. The activator mechanism comprises axially-aligned cylindrical end cams with generally complementary surfaces that upon rotation of a driven cam axially extends a follower cam compressing a power compression spring, and upon encountering a cam lobe the driven and follower cams abruptly come together releasing the spring delivering the desired impact to the blade.

Abstract: A method for mechanically stripping the protective coating from a silica or glass optical fiber using a polymeric or soft metal blade having a hardness less than that of the glass optical fiber but greater than the protective coating. The blade is preferably selected from a group of polymeric materials, or alternately a soft metal, which is selected or treated so as to not detrimentally oxidize in conventional operating environments. For a silica-containing optical fiber, the blade has a hardness of less than approximately 125 on the Knoop hardness scale, and preferably less than approximately 60 on the Knoop hardness scale. A method of inhibiting damage to the exposed region of the silica-containing optical fiber comprises applying a substance that forms a protective layer to provide a barrier to particulates and moisture, and which does not inhibit subsequent processing of the optical fiber, selected from a group of silane-containing compounds.
