pamphlets U.S. 2018/0 281 706 A1 as well as EP 1 589 541 A1 disclose generically a cable arrangement having a signal sub-cable and a power sub-cable in a common cable jacket, which has thermoplastic polyurethane.

In EP 3 340 392 A1 proposes a junction mold structure of a cable assembly, the junction mold structure being injection molded from polyurethane.

The invention is based on the object of proposing a cable arrangement which is particularly suitable for connecting a wheel speed sensor and an electric parking brake and which is inexpensive and/or enables simple manufacture and/or is robust and reliable.

This object is achieved according to the invention by the cable arrangement according to claim 1.

The feature that at least in the first segment, the first and the second partial signal line are arranged on opposite sides of the second electrical line, preferably relates to the cross section through the first segment or through the common cable of the first segment.

It is preferred that the first and second signal sub-line are arranged on opposite sides in an intermediate space or project into an intermediate space between the first and second power sub-line. This structure expediently refers to a cross section through the first segment or through the common cable of the first segment. In this context, an intermediate space is understood to mean in particular the gusset between the first and second partial power line. A sub-line is preferably understood to be an individual line of a specific group of lines; it is expedient to always use two sub-lines of one type, which in particular are of essentially identical design.

The term cable arrangement is preferably understood to mean a cable harness.

The terms hose, tubular jacket and/or jacket and/or jacket-shaped hose are expediently used synonymously.

The term bundling is preferably understood to mean arranging and/or guiding the partial lines together so that they are arranged or run together in the corresponding segment. This can be achieved or reinforced in particular by at least partial twisting and/or compacting.

The term twisting is preferably understood to mean twisting or stranding.

The power cores are preferably designed in such a way that they are designed for operation with a current load of at least 1A or more than 5A or in particular more than 10A.

The first electrical line preferably does not have an independent sheath around the at least first and second signal sub-line.

According to the invention, the common first sheath made of thermoplastic polyurethane of the first segment of the cable arrangement is tubular and is pulled onto the sub-lines of the first and second electrical line, enclosing them together and in particular is not extruded around these sub-lines.

It is expedient that the first electrical line is designed as a signal line for connecting a wheel speed sensor in a motor vehicle and the second electrical line is designed as a power line for connecting an electric brake actuator, in particular an electric parking brake, in a motor vehicle.

It is preferred that the partial lines of the first and second electrical lines are stranded together, this common stranding being formed in particular in one direction of rotation.

In particular, in the first segment of the cable arrangement, in the course of bundling, the two signal sub-lines twisted together with the two power sub-lines are or are stranded in threes or twisted or in pairs, i.e. the signal sub-lines that are already twisted the power sub-lines, which are twisted together, are twisted together as two sub-bundles to form a total bundle or the two signal sub-lines and the two power sub-lines are all stranded or twisted together in fours without prior bundling or without stranding in pairs.

According to the invention, the cable arrangement has a first branching form structure, into which the partial lines of the first and second electrical lines each protrude or are passed through, the common jacket of the first segment also protruding into the branching form structure and being received by it in a substantially sealing manner ,
wherein the branch mold structure is designed as an injection molding or transfer molding component made of a plastic, TPU or thermoplastic polyurethane.

It is preferred that the signal splits are common and the power splits are common before the first segment and/or substantially adjacent to the first segment opposite the first location of the cable assembly and/or at a defined second location of the cable assembly to a fourth and fifth segment of the cable arrangement are branched off, after which the branched-off signal sub-lines of the fourth segment are fitted with a substantially tubular fourth jacket and the branched-off power sub-lines of the fifth segment are fitted with a substantially tubular fifth jacket. Alternatively, preferably, instead of branching off, the signal sub-lines and/or the power sub-lines, in particular each, is connected to an extension sub-line, which alone or together has a jacket, with these continuation-signal sub-lines forming a fourth segment of the cable arrangement and a have a fourth sheath and/or these extension power sub-lines have a fifth segment of the cable arrangement and have a fifth sheath. The fourth and fifth segment of the sub-line is particularly preferably provided for connecting the cable arrangement to an electronic control unit or a bus and very particularly preferably each have a plug for this purpose.

In the area where the fourth and fifth segment of the cable arrangement branches off from the first segment of the cable arrangement, the cable arrangement expediently has a second branching structure which separates the hose ends or jackets there, i.e. the first, fourth and fifth jacket of the respective first, fourth and fifth jacket absorbs and seals.

It is expedient for the first and/or the second branching mold structure to be formed by overmoulding, in particular from a thermoplastic, for example thermoplastic polyurethane or polyamide or nylon or PBT, polybutylene terephthalate, with the hose end or jacket end of the first , second and third hose and/or the first, fourth and fifth hose or jacket is overmolded.

It is particularly preferable for at least one sealing molding to be inserted into the space between the inner hose jacket and the partial lines or strands before the overmoulding to form the first and/or second branching mold structure, so that no mold or injection molding compound runs into the hose during overmoulding, with this Sealing molding is formed in particular from rubber and / or plastic, or the cable assembly is formed accordingly.

In particular, the first and/or the second branching form structure is positioned on the cable arrangement in such a way that the partial lines or partial line sections that are exposed between the adjacent ends of the, in particular tubular, jackets in the area of a branching are particularly preferably in a defined area or completely , are housed and/or enclosed by the branch shape structure.

It is expedient that the outer lateral surfaces of the hose ends or casing ends of the first, second and third hose and/or the first, fourth and fifth hose or casing arranged at the branching, in particular at least within a defined area, circumferentially surround the outer lateral surface of the respective hose end or jacket end, in each case, in particular before the overmolding, are roughened with a laser and/or activated and/or activated with a plasma and/or cleaned/are.

It is preferred that at least one or more or all hose ends or jacket ends of the tubular jackets or jackets used are roughened and/or activated with a laser at least in a defined area, in particular once around the outer jacket with a defined width. and/or are/are subjected to a plasma activation process and/or a plasma cleaning process. This enables the hose end or jacket end to be overmoulded on a plug or sensor or a branching mold structure with improved tightness. This helps in particular when the tubular jacket is made of PVC or polyvinyl chloride, which is relatively inexpensive.

It can expediently different methods of generating plasmas for Plasma activation and/or plasma cleaning can be used, such as the application of high-frequency alternating voltages to a gas or the related use of direct current and/or the excitation of a gas with microwaves. Exemplary plasma treatment gas mixtures include oxygen, argon, hydrogen, and/or nitrogen. The type of mixture depends on the special requirements of the plasma treatment process, which result, for example, from the type of contamination and the material being treated. Depending on the type of gas mixture, the plasma has an oxidizing or reducing or activating effect. Oxidizing plasmas are suitable for removing organic contaminants, while reducing plasmas are also suitable for removing inorganic scale and/or breaking down oxide scales.

A plasma cleaning process is preferably understood to mean a dry, non-contact, chemical and/or physical, non-abrasive cleaning process with which the highest cleaning qualities can be achieved. Organic impurities in particular are converted into water vapor, carbon dioxide and/or CH ₄ , for example, by chemical reaction with free radicals in the plasma. For chemical removal of contamination, the plasma contains, for example, oxygen or hydrogen or argon. Oxygen is suitable for removing organic contamination and hydrogen for removing inorganic and/or organic substances and for reducing oxides. The cleaning process is expediently a combination of a physical and a chemical active process or alternatively preferably exclusively a chemical active process (ion-free). Physical: If, for example, the object to be cleaned is connected to a cathode for plasma generation, positive ions from the plasma are accelerated in its direction due to the electric field applied. Upon impact, these ions detach atoms and molecules from the surface through direct momentum transfer.
Chemical: Excited oxygen and oxygen ions form carbon dioxide and water when reacting with hydrocarbons, for example. Excited hydrogen forms, for example, halides, sulfides, CH _x and water vapor.

A plasma activation process is preferably understood to mean a plasma treatment process for increasing the surface tension or surface adhesion of the body or tubular jacket or jacket to be treated or activated. In this case, the adhesion between the body is reinforced with a material to be applied, for example molding material or material for overmolding. This body or jacket or its surface area is therefore easier to wet or to encase in an adhesive manner by an agent or substance, in particular a liquid. The contact angle of a drop on the body is a common measure of the body's surface tension. If the surface of the body is hydrophobic (water-repellent), it has a low surface tension. By means of a plasma activation process, the surface tension can be increased in the same way as with an adhesion promoter. After the plasma activation process, the surface of the body is hydrophilic or easily wetted, the contact angle is reduced and the tendency to delamination is lower. Nitrogen and/or oxygen, for example, is used for a plasma activation process.

Activation with a laser is preferably understood to mean a partial destruction of the molecular structure of the surface of the body or of the tube in the form of a jacket in a defined area, so that free radicals are formed on this surface. These free radicals are capable of entering into chemical and/or physical compounds with the encapsulation material, so that these can no longer be detached from the surface of the hose or jacket in the form of a jacket.

Roughening with a laser is preferably understood to mean enlarging or furrowing the effective, in particular already activated, surface and thereby increasing the adhesive effect between the encapsulation material and the surface of the jacket-like hose or jacket.

It is expedient for the first and/or the second branching form structure, in particular in each case, to have at least two housing elements, in particular designed as two prefabricated half-shells, which connect the hose ends of the first, second and third hose or jacket and/or of the first, fourth and fifth hose or casing and seal them at least in a form-fitting manner, in that the at least two housing elements, which accommodate these three hose ends or casing ends, are joined together and fixed, in particular by clipping the two half-shells, which each have at least two clipping elements for this purpose . The joined and fixed two half-shells particularly preferably form a closed housing of the first and/or second branching mold structure.
