Description

The invention relates to a cable arrangement according to the preamble of claim 1.

Cable harnesses for the common connection of a wheel speed sensor and an electric parking brake are known, such as in the documents JP5541331 and W02015 / 090658A1 disclosed.

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 production 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-lines are arranged on opposite sides in a space or protrude into a space between the first and second power sub-lines. This structure expediently relates to a cross section through the first segment or through the common cable of the first segment. A gap is understood in particular to mean the gusset between the first and second power sub-lines.

A sub-line is preferably understood to mean an individual line of a specific line group; two sub-lines of one type are expediently always used, which are in particular essentially identical.

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 a joint arrangement and / or routing of the sub-lines so that they are arranged or run together in the corresponding segment, this can be achieved or reinforced in particular by at least partially twisting and / or compacting.

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

The power wires are preferably designed such 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 jacket around the at least first and second signal sub-lines.

It is preferred that the common first sheath of the first segment of the cable arrangement is formed from thermoplastic polyurethane, which at least surrounds the first and second electrical lines and is extruded around them.

The common first sheath made of thermoplastic polyurethane of the first segment of the cable arrangement is tubular and is drawn onto the partial lines of the first and second electrical lines, enclosing them together, and in particular is not extruded around these partial 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 electrical brake actuator, in particular an electric parking brake, in a motor vehicle.

It is preferred that the sub-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 the bundling, the two signal sub-lines twisted together with the two power sub-lines are twisted or twisted in pairs or in pairs, i.e. the signal sub-lines that are already twisted with 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 together with one another, without previous bundling or without twisting in pairs stranded or twisted.

It is preferred that the cable arrangement has a first branching structure, into which the sub-lines of the first and second electrical lines each protrude or are guided through, the common sheath of the first segment likewise protruding into the branching structure and essentially sealing from it Way is recorded
the branching mold structure being formed as an injection molding or injection molding component from a plastic, in particular from TPU or thermoplastic polyurethane. It is preferred that the signal parts together and the power sub-lines together in front of the first segment and / or essentially adjacent to the first segment opposite the first point of the cable arrangement and / or at a defined second point of the cable arrangement to a fourth and fifth segment of the cable arrangement are branched off, after which an essentially tubular fourth jacket is put on the branched signal sub-lines of the fourth segment and an essentially tubular fifth jacket is put on the branched power sub-lines of the fifth segment. Alternatively, instead of branching, the signal sub-lines and / or the power sub-lines, in particular in each case, an extension sub-line is connected, which alone or together have a jacket, these extension-signal sub-lines forming a fourth segment of the cable arrangement and one have 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 segments of the sub-line are 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.

The cable arrangement expediently has, in the region of the branching off of the fourth and fifth segments of the cable arrangement from the first segment of the cable arrangement, a second branching structure which has the hose ends or sheaths there, i.e. the first, fourth and fifth sheaths of the first, fourth and fifth sheaths picks up and seals.

It is expedient for the first and / or the second branching structure to be formed by extrusion coating, in particular made of a thermoplastic, for example made of thermoplastic polyurethane or polyamide or nylon or PBT, polybutylene terephthalate, the hose end or jacket end of the first arranged on the branching in each case , second and third hose and / or the first, fourth and fifth hose or jacket is also encapsulated.

It is particularly preferred to insert at least one sealing molded part into the space between the inner hose jacket and the partial lines or strands in order to form the first and / or second branching mold structure, so that no mold or injection molding compound runs into the hose during the encapsulation, whereby this Sealing molding is made in particular of rubber and / or plastic, or the cable arrangement is designed accordingly.

In particular, the first and / or the second branching 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, sheaths in the region of a branching, particularly preferably in a defined region or completely , are housed and / or enclosed by the branch structure.

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

It is preferred that at least one or more or all of the 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 subjected to a plasma activation process and / or a plasma cleaning process. In this way, the encapsulation of the hose end or jacket end on a plug or sensor or a branching structure with improved sealing is made possible. This helps in particular if the tubular jacket is made of PVC or polyvinyl chloride, which is relatively inexpensive.

Various methods of generating plasmas for plasma activation and / or plasma cleaning can expediently be used, such as, for example, the application of high-frequency alternating voltages to a gas or the use of direct current in this regard and / or the excitation of a gas with microwaves. Exemplary gas mixtures for plasma treatment contain oxygen, argon, hydrogen and / or nitrogen. The type of mixture depends on the special requirements for 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 deposits and / or for reducing oxide deposits.

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. In particular, organic impurities are converted into water vapor, carbon dioxide and / or CH ₄ by chemical reaction with free radicals of the plasma. For chemical removal of contamination, the plasma contains, for example, oxygen or hydrogen or argon. Oxygen is suitable for removing organic contaminants 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 process or, alternatively, preferably only a chemical process (ion-free). Physically: 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 applied electrical field. Upon impact, these ions detach atoms and molecules from the surface by direct momentum transfer.
Chemical: Excited oxygen and oxygen ions, for example, form carbon dioxide and water when they react with hydrocarbons. 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 to increase the surface tension or adhesion of the body to be treated or activated or the tubular jacket or jacket. The adhesion between the body is strengthened with a material to be applied, for example molding material or material for extrusion coating. This body or jacket or its surface area is thus easier to wet or, in particular, to be coated with an adhesive, in particular a liquid, or substance. The contact angle of a drop on the body is a common measure of the surface tension of the body. If the surface of the body is hydrophobic (water-repellent), it has a low surface tension. By means of a plasma activation process, an increase in surface tension is achieved, as with an adhesion promoter. The surface of the body is hydrophilic or readily wettable after the plasma activation process, the contact angle is reduced and the tendency to delamination is lower. For example, nitrogen and / or oxygen is used for a plasma activation process.

Activation with a laser is preferably understood to mean partial destruction of the molecular structure of the surface of the body or of the jacket-shaped tube in a defined area, so that free radicals arise on this surface. These free radicals are able to form chemical and / or physical connections with the encapsulation material, so that it can no longer detach from the surface of the jacket-shaped hose or 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-shaped hose or jacket.

The joined and fixed two half-shells particularly preferably form a closed housing of the first and / or second branching structure.
