A peeling apparatus 1 includes a first peeling die and a second peeling die respectively including a pair of cutting blades 251 that peels the insulating film by being moved in a direction perpendicular to an axial direction of the conductive wire material 2 to cut the insulating film, and a support die 253 that supports a side surface of the conductive wire material 2 from a downstream side in a moving direction of the cutting blades 251 at the time of cutting by the cutting blades 251, the support die 253 of the first peeling die including a convex portion 2533 protruding toward the conductive wire material 2.

An insulating film removal method according to the present disclosure includes first, second, and third removal steps. In the first removal step, an insulating film coated on a junction surface and an opposed surface opposed to the junction surface is removed, the junction surface being a surface where a rectangular conductor is joined with another rectangular conductor. In the second removal step, a corner of the rectangular conductor is removed so that a burr is formed on the junction surface and a side surface, the side surface adjoining the junction surface and the opposed surface. In the third removal step, the insulating film coated on the side surface is removed so that a burr is formed on the junction surface side.

A cable clamping device for widening a braided shield of a cable includes at least three clamping bodies that are arranged to form an equilateral polygonal passage for clamping the cable therein. The clamping bodies are slidable against each other to change the opening size of the passage.

An exposed terminal for a wire conductor, and a process for preparing the exposed terminal includes executing, via a mechanical device, a mechanical ablation process to remove the insulative material from an outer surface of the plurality of square edges along a predefined length of the portion of the wire conductor. The process also includes executing, via a laser tool, a laser ablation process to remove the insulative material from the first pair of opposed faces along the predefined length of the portion of the wire conductor; and executing, via the laser tool, the laser ablation process to remove the insulative material from the second pair of opposed faces along the predefined length of the portion of the wire conductor.

The cable aluminum foil stripping tool includes two tool half-bodies adapted to clamp an exposed aluminum foil layer of a cable from two sides of the cable. Each tool half-body includes a body portion and a tooth-shaped rib formed on an inner side of the body portion and having a tooth-shaped cross section. The tooth-shaped rib scrapes off the exposed aluminum foil layer from the cable when the two tool half-bodies clamping the exposed aluminum foil layer are moved relative to the cable. The cable aluminum foil stripping tool includes an inner insulating layer wrapped by the exposed aluminum foil layer of the cable. The inner insulating layer is elastically deformable when contacting the tooth-shaped rib, such that the inner insulating layer is not scratched by the tooth-shaped rib.
