According to different embodiments, a cable guide (100 to 500, 1302) can comprise: a fastening structure (102), a plurality of guide ducts (104), arranged next to one another, which are coupled to one another by means of the fastening structure (102) and each guide duct of which comprises two serpentine curve-shaped duct segments (104a, 104b) between which the fastening structure (102) is arranged, wherein the two serpentine curve-shaped duct segments (104a, 104b) are configured resiliently in such a way that they can be compressed toward the fastening structure (102) and expanded away from the fastening structure (102) counter to a spring force.

Energy chains, namely chain parts, in particular chain link plates, therefor and guiding parts of a guide trough for an energy chain. The chain part or guiding part comprises a formed part made from plastic, on which a functional electric circuit with a sensor function is arranged. The functional circuit comprises at least one trace conductor structure, which is formed on the formed part as the carrier of the trace conductor structure, e.g. is applied by an additive manufacturing method.

A line guiding system comprising an articulated line guiding apparatus which, for guiding supply lines between two connection points that are movable relative to each other, is curved about a deflection axis extending in a transverse direction transverse to the longitudinal direction, and a separate guiding device for guiding the line guiding apparatus along at least a section of the travel path. The guiding device comprises at least one guide strand, which is arrangeable for predefining a desired course of the section of the travel path. The line guiding apparatus comprises external profile regions, which are arranged for lying against and/or on the guide strand and are shaped with a profile shape for a transversely stabilizing guiding against or on the guide strand by projecting and/or recessed interengagement of guide strand and profile shape to counteract a lateral deviation of the movable line guiding apparatus in the transverse direction.

A machining unit for use on a machining tool has a head carrier that is attachable to the machine tool and has a head carrier housing , a swivel head that is provided to swivel relative to the head carrier about a swivel head rotation axis and has a swivel head housing, a spindle head that is attached to the swivel head and has a working spindle , and a cable run that extends inside the head carrier housing to the swivel head and has a plurality of members that are arranged in succession along the cable run and are connected movably together. Adjacent members are in this case able to rotate and swivel relative to one another and each member has a central piece and a sheathing spaced apart therefrom. The central piece is connected to the sheathing via one or more connection elements.

A line guide device comprising a displaceable flexible envelope with duct-like sheaths for lines and end fastening devices in each case comprising two clamping plates with major faces for exerting a clamping force and within each case a retaining portion for strain relief elements. The retaining portion retains the strain relief elements on the respective clamping plate against displacement in the longitudinal direction and, according to the invention, forms a profile cross-section with undercut. The strain relief elements each have at least one connection portion which, for form-fitting engagement behind the undercut, corresponds to the profile cross-section of the retaining portion in order also to retain the strain relief element on the clamping plate in the direction perpendicular to the major face. A variant of the end fastening device comprising two plate connectors for holding the clamping plates together in each case on a lateral end portion, in each case with two opposing clip portions for form-fitting interaction with an end region.

A line guide device comprising an envelope for supply lines and an articulated support chain. One chain link has an inside projection in a first longitudinal portion and an inside cross-bridge with an extended stop face and a recess adjoining the cross-bridge in a second longitudinal portion. In the extended position, the projection of one chain link engages in the recess of the following chain link and on the cross-bridge thereof. A support chain, in which each chain link has, in its second longitudinal portion, an outside cross-connection which in the arcuate position interacts with an outside arc stop face of the first longitudinal portion and has an inside cross-connection which in the extended position interacts with an inside extended stop face of the first longitudinal portion.

A dynamic line guiding system for high speeds and/or long displacement paths, with an energy chain arranged as lying on the side, which chain, in the configuration of a first strand, a second strand, as well as a deflection curve, is displaceable back and forth. The energy chain is guided in a guide trough with two laterally-opposite side walls and a trough floor therebetween, wherein each strand is respectively displaceable with a lateral surface on a respective bearing surface on the trough floor, and is held, relative to the outside, by means of one of the two side walls. It is provided that the trough floor comprises at least one bearing surface with a step or a ramp, which counteracts a deviation of the first strand out of its intended target location on the respective bearing surface.

At least one first section of a cable guide for receiving energy or communication cables in a receiving area can be arranged in the form of a first and second strand (3, 4), which are connected together by a deflecting region (2) extending about a deflecting arc, wherein the cable guide can be moved about the deflecting arc of the deflecting region (2). The aim of the invention is to allow a movement of the cable guide about the deflecting arc in the most frictionless manner possible while keeping the deflecting region stable. This is achieved in that a stabilization element (5) is provided which is substantially adapted to the deflecting arc and is arranged in a deflecting region (2) guide area that extends along the first section of the cable guide and passes through said section at least in one region and which supports the deflecting region (2) in the guide area in a floating manner when the cable guide is being moved about the deflecting arc without emerging from the guide area.

A machine tool including a base, a slider that is supported to be linearly movable in a direction with respect to the base, a ball screw configured to cause the slider to linearly move with respect to the base, and a chain-like carrier used for wiring a movable wire body between the base and the slider. The carrier is disposed between the base and the slider and curved in a U-shape around an axis extending in a direction in which the base and the slider are apart from each other, one end of the carrier is fixed to the slider and an other end of the carrier is fixed to the base, and a curved portion of the carrier, which is curved in the U-shape, is disposed at a position where the curved portion crosses an extension line of an axis of the ball screw.
