The main body portion, the heating portion and the holding portion are located in this order in the axial direction, and the heating portion includes a vibration notification portion giving information to an operator by vibrating.

A device for simultaneously stripping at least two cable ends surrounded by insulation material includes a cutting device having first and second cutters that are movable relative to each other in a direction perpendicular to the longitudinal direction of the cable ends. The cutting edges of the first and second cutters are disposed substantially in the same plane and are movable towards each other such that the cutting edges simultaneously cut into the insulation material of the at least two cable ends. In addition, the cutting device and the cable ends are movable relative to each other in the longitudinal direction of the cable ends to simultaneously pull-off the cut insulation material from the at least two cable ends and thereby strip the at least two cable ends.

Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable. The computing device may determine one or more target cutting distances and determine whether an actual cutting distance satisfies the target cutting distance. The computing device may detect defects in the electrical cable. The computing device may further determine whether the cable preparation device should be serviced.

An electric wire processing apparatus (1) includes: a clamp (3R) to grip and convey an electric wire (5); an upper tray (21) disposed under a movement path (51t) for a first end (51) of the electric wire (5); a nonconforming item tray (23) disposed under the movement path (51t) and laterally of the upper tray (21); a shared tray (24) disposed toward a second end (52) of the electric wire (5) relative to the upper tray (21) and the nonconforming item tray (23); a conforming/nonconforming determiner (14) to determine whether the electric wire (5) has been processed successfully; and a controller (9) to cause, upon determination by the conforming/nonconforming determiner (14) that the electric wire is a conforming item, the clamp (3R) to release its grip on the first end (51) of the electric wire (5) when the first end (51) is located over the upper tray (21), and to cause, upon determination by the conforming/nonconforming determiner (14) that the electric wire is a nonconforming item, the clamp (3R) to release its grip on the first end (51) of the electric wire (5) when the first end (51) is located over the nonconforming item tray (23).

The present disclosure relates to the technical field of cable processing, and discloses a method for processing a reaction force cone of a cable main insulating layer. The method includes: two ends of a cable are clamped through a clamping device, and the cable is enabled to pass through a cutting device; a cutting depth of the cutting device in a radial direction and a cutting position of the cutting device in an axial direction are adjusted; the cutting device is started, and the cable is cut by the cutting device to form the reaction force cone.

A method of reducing entanglement of wires includes receiving, at a tray, one or more first wires of a first wire group from a wire feed system of a wire processing machine. In addition, the method includes receiving, at the tray, one or more second wires of a second wire group from the wire feed system after receiving the first wire group at the tray. The method further includes physically separating, using a separator device associated with the tray, at least a portion of the first wire group from the second wire group. The method also includes moving the second wire group relative to the first wire group, reducing movement of at least a portion of the first wire group relative to a tray surface during movement of the second wire group relative to the first wire group.

A shield trim is performed by tearing bunched shield strands circumferentially along a circular edge. The apparatus includes a pair of aligned metal plates that have been drilled through multiple times such that holes of varying diameters pass through both plates. A cable gripper on the entry side of the device clamps the cable in place. A shield gripper on the rear side of the device closes over the exposed shielding of the cable, and the two plates are pushed together. The shield gripper travels with the rear plate, pushing the shield over the wires and causing the shield to bunch between the two plates. With the two plates pushed together, both grippers open and the cable is pulled free from the device. This pull forces a stress concentration which tears the shield strands across the sharp edge of the hole, producing a uniformly trimmed shield.

The invention relates to a device (21) for working an electrical cable (1) which has a sheath (6) and a cable film (5) situated beneath said sheath, comprising an assembly (32) of modules (33, MD1, MD2, MD3, MD4), which are independent of one another, for removing a piece (6′) of sheath and a piece (5′) of cable film from the cable (1). According to the invention, provision is made for the assembly (32) to have a first module (MD1) for cutting off the piece (6′) of sheath from the cable (1), a second module (MD2), which follows the first module (MD1), for reducing the mechanical loadability of the cable (5) in an intended crack position (RP), and a third module (MD3), which follows the second module (MD2) and has the purpose of removing the piece (6′) of sheath and the piece (5′) of cable film from the cable (1) in an automated manner.
