Techniques, systems, and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a handheld 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.

A cable such as a server cable may have a tapered termination portion that when connected to other information handling system components reduces the loss of signal between the cable and the information handling system component. A method of making a cable with a tapered termination portion comprising heating a wire having an end and a body portion, the body portion having a first diameter; pulling the end relative to the body portion, for example with a clamp coupled to the end under tension, to obtain a location between the end and the body portion having a second diameter smaller than the first diameter; and cutting the wire at the location.

An electric energy transmission joint and a preparation method therefor. The electric energy transmission joint includes an electric energy transmission copper part, an electric energy transmission aluminum part (9), and an aluminum wire (3). The electric energy transmission copper part includes a fixer (1) for connection with an electric consumption device, and a connector (2) for connection with the electric energy transmission aluminum part (9). A first through hole is provided inside the electric energy transmission aluminum part (9), and a second through hole is provided inside the connector (2). An aluminum conductive core (4) exposed by stripping an insulation layer (5) from a front end of the aluminum wire (3) is inserted into a cavity formed by the connection of the first through hole and the second through hole. The electric energy transmission aluminum part (9) is connected to the aluminum wire (3) by crimping. The electric energy transmission copper part has the advantages of light weight, fast production, and reduced production cost.

Prior to insertion into the recess of a crimping region, the axial ends of the plurality of electrical strands of the cable are fixed with a clamping tool so that the axial ends of the plurality of electrical strands protrude axially out of the clamping tool and the ends of the plurality of strands protruding axially from the clamping tool are sheared off in the transverse direction with a cutting tool so that a closed end face is produced at the axial end of the strands. The axial end of the plurality of electrical strands is inserted into the recess and the plurality of strands are welded to the contact piece by melting the closed end face arranged in the recess by radiation energy of a radiation directed onto the end face.

The invention relates to a method for manufacturing an electric cable (2), according to which the cable (2) is successively processed in processing modules (41, 43) that are independent from one another. According to the invention, at least one sheath clamp (10.1, 10.2, 10.3, 10.4), which is independent from the plug connectors (22) that are to be mounted on the cable (2) during manufacturing, is attached to a cable sheath (9) of the cable (2) in a non-positive fit at a defined axial position along the longitudinal axis (L) of the cable (2). Alternatively or in addition, the cable (2) is attached to a cable carrier (4), wherein the cable carrier (4) comprises at least one stop element (44) which is arranged at a defined axial position along the longitudinal axis (L) of the cable (2).

A rubber plug holding device 30 includes a plurality of first clamp members 31 located around a predetermined central line CL so as to form a space 51 inner thereto in which a cylindrical rubber plug 5 is allowed to be located; a first support member 32 supporting the first clamp members 31; and a first actuator 33 driving the first clamp members 31. The plurality of first clamp members 31 include three or more first rubber plug contact portions 31e1, which are on the space 51 inner thereto and are to be in contact with an outer circumferential surface of the rubber plug 5. The first support member 32 supports the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL. The first actuator 33 drives the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL.

A system for the automated manufacture of a wiring harness, which demonstrates a branched structure made up of multiple individual conductor elements. To form wiring harnesses having an individually branched structure, the conductor elements are automatically brought into a predefined distribution structure, multiple second rails oriented in parallel to each other and multiple second transporters, distributed on the second rails, being used for this purpose. The second transporters are each fitted with one wire end of the conductor elements. To form the distribution structure, the second rails are subsequently moved in a vertical direction, and the second transporters are moved along the second rail. In this spread-apart structure, additional processing steps are carried out, for example a fixing of the conductor elements to each other.
