摘要:
A slitter is disclosed for slitting a cable-like item longitudinally to a controlled depth with a blade. The cable-like item is drawn through a guide which is shaped to correspond to the cross-section of the item, thereby ensuring proper twist as the item is drawn under the slitter blade.

Apparatus for separating individual conductor elements in a multiple-conductor flat ribbon cable including a rotatable cutting element for cutting the insulating sheathing of the cable along each of the score lines running between the individual conductor cores. The cutting element is provided with a plurality of protruding arcuate cutting edges each interrupted by a shorter indrawn non-cutting edge. Further provided is a cable support element adapted to press a cable inserted into the apparatus against the cutting edges, but not against the indrawn edges. When the indrawn edges face the cable support element, a feed-in and feed-out gap is provided for easy insertion and removal of the cable.

A tool for use in stripping plastic sheath from electrical cable has first and second handles pivotally connected in a scissor-like configuration so that each handle has a grip portion and a jaw portion. Each jaw portion carries a jaw element with a transverse cutting blade and a longitudinal slitting blade. The cable is inserted between the jaw elements so that it extends through the tool between and generally parallel to the handles. When the grip portions are moved together, the jaw elements engage the cable so that each transverse blade makes a transverse cut through the plastic sheath. At the same time each longitudinal blade makes a slit in the plastic sheath near the transverse cut. The tool is then pulled toward a free end of the cable so that each longitudinal blade slits the plastic sheath to the free end. The transverse blades are pivotally mounted on the jaw elements so that they swing away from their cutting position when the tool is moved along the cable. The slit parts of the cable are then peeled away from the interior wires and broken off from the sheath at the transverse cuts.
摘要:
A tool for the selective severing of a conductor in a multi-conductor flat cable and preforming the remaining free end comprising a punch means with a first conductor relief slot and a die means with a second conductor relief slot such that when the die and punch means are applied to a conductor it is severed and the free end trapped between the first and second conductor relief slots. Guides on the tool and die means permit alignment of the tool with a selected conductor while grooves on the die means prevent unwanted cable movement.
摘要:
A method for separating the signal carrying conductors from the ground conductors in a plural conductor flat cable to enable the connection of the ground conductors to a grounding plane and the insertion of the signal conductors into the terminals of a connector block. The method comprises the steps of severing the insulation surrounding the ground and signal conductors in a flat conductor cable, sliding the severed insulation along the conductors away from the main body of the cable, bending the ground conductors at right angles with respect to the flat cable, and sliding the insulation back along the signal conductors until it abuts the main body of the flat cable.
摘要:
A mechanical apparatus and tool for clearing small areas of the plastic film insulation in flat flexible circuits and cables to permit making electrical connections to the metal foil conductors. An end-mill-like rotating cutter is fed into the laminated workpiece. Novel cutter geometry provides differential requirements of feed force and torque, cutting two to three times more easily into plastic than into copper. Means are provided to limit the feed force to prevent penetration into the copper foil. Means responsive to torque may be employed to retract the cutting tool automatically. A novel spring-loaded telescoping chuck is applicable to limit the feed force in single-spindle or multiple-spindle machines. The sides of the tool are slightly hollow-ground to reduce the feed-force required. The lips may be ground slightly convex to compensate for the elastic indentation of the workpiece.
摘要:
A machine for preparing cable is provided which has an adjustable block portion and an opening therethrough for receiving insulated conductors and includes securing and shearing members mounted thereon. A cable preparation area has an opening therein for receiving insulated conductors passing through the adjustable block portion. The machine is characterized in that, simultaneously, insulated conductors may be sheared and prepared at their ends respectively.
摘要:
An electrical wire stripping and cutting tool particularly adapted for stripping the insulation from Romex wire and the like, having a scissor-like tool including a cutting blade disposed on the end thereof over an offset guideway for permitting the cable to by guided through the guideway during the stripping operation. A means is also provided for controlling the depth of the cut of the blade.
