  • the assignment thus defines which conductors are assigned/belong to which contact element. In other words, it depends on the specific arrangement and/or assignment of the component's contact elements to the cable's conductors.
  • the cable may have at least one electrical conductor. It is preferred if at least two or three or four or more or a maximum of 10 or a maximum of 15 or a maximum of 20 electrical conductors are provided.
  • Each of the electrical conductors may particularly preferably be configured as a stranded wire.
  • a stranded wire is defined as In particular, this term refers to an electrical conductor comprising thin individual wires and therefore easily bendable, which is made predominantly of copper, for example.
  • the individual wires may be enclosed by a common insulating sheath (insulation); in this case, this cable with the conductor can also be referred to as a stranded wire.
  • At least one coding can be provided on the cable.
  • the coding can be formed spatially, i.e. in particular three-dimensionally, on the cable.
  • the coding can be provided on a contacting and in particular cutting surface of the cable. It is also possible for the coding to be provided on several or all cross-sections of the cable in order to provide a possible contacting and/or cutting surface here. This is the case, for example, if the coding extends repeatedly or continuously in the longitudinal direction of the cable in order to be provided on a cutting surface even if the cable is cut open at any point along this extension.
  • the coding can serve to specify a specific arrangement and/or (in particular the above-described) assignment of, in particular electrical, contact means of the component with the, in particular electrical, conductors of the cable, preferably to specify and/or guide this for the connection. Coding can preferably be understood as a systematic shaping and/or a systematic arrangement of contacts and/or mechanical elements in order to ensure a specific connection configuration.
  • the coding can therefore serve to avoid incorrect connections and to ensure the correct alignment of the component (e.g. in the form of a connector) with respect to the cable during the connection process.
  • the coding thus advantageously defines a correct alignment of the component, i.e. the correct orientation of the cable, preferably in relation to the cable, and enables optimized signal transmission and power supply by ensuring compatibility.
  • the arrangement of the contact means with the conductors can, for example, refer to the spatial arrangement, e.g. B. according to the assignment, i.e. a predetermined configuration, so that the "correct" contact means (in particular a contacting movement) contact the "correct" conductors.
  • the connection between the component and the cable can be made directly at a contacting surface, in particular a cutting surface, of the cable.
  • the contacting surface can refer to a surface, and in particular a cross-section through the cable, at which the respective conductor of the cable is or can be accessible from the outside for contacting the contact means of the component.

  • the respective conductor The cable can be directly adjacent to an outer region of the cable at the contacting surface and thus connected to the contact means of the component without severing the sheath and/or insulation of the cable. Furthermore, the respective conductor can be severed at the contacting surface in alignment with the contacting surface.
  • the cable can be designed to provide such a contacting surface after the cable has been cut to size.
  • the cable can be designed in such a way, preferably after the cable has been cut to size, that the respective conductor of the cable is or becomes accessible for contacting with an associated contact means.

  • the cable can also have the contacting surface and/or the accessible conductor in its original state (e.g. in the delivered state without cutting).
  • the coding can be provided directly on the cable (and thus not or not only on the connector).
  • the coding can be formed between and/or in the area of and/or through the conductors and/or the insulation and/or in or on the cable sheath (e.g. inner and/or outer sheath) on the cable. Coding is already known in connectors, in particular through electrical coding, in which the contacts are arranged such that only the correct electrical connection is possible.
  • this coding can be transferred to the cable, i.e., alternatively or additionally provided on the cable, e.g. in the form of mechanical and/or electrical coding.
  • the coding can optionally also be referred to as a coding or connection structure.
  • While mechanical coding preferably systematically predetermines a specific shape for at least part of the cable or on the cable
  • electrical coding allows the cable conductors to be arranged in such a way that only the correct electrical connection to the component is possible.
  • Applying the coding to the cable can have the advantage of significantly simplifying and accelerating the connection process between the cable and component. This is due to the fact that the component can be connected directly and immediately to the cable.
  • the cable according to the invention can have a coding and/or a connecting structure which runs in the axial direction (longitudinal direction) of the cable and/or the conductors of the cable.
  • the connecting structure can have the coding and/or a plug-in structure and/or a (geometric) profile.

  • the coding can optionally be provided by a specific geometric shape (in particular a polygon) of the (respective) cavity.
  • the coding can also be defined by a number of corners and/or edges of this shape. It is also conceivable for the coding to be provided by several of the cavities, e.g. based on the arrangement and/or size and/or possibly different shapes of the cavities.
  • the coding or connection structure allows for a significant reduction in the assembly steps required for connecting a cable to a component. Furthermore, even after the cable has been cut to size, the cut cable itself can already exhibit the necessary structure to enable direct connection to the component.
  • the cut cable can have a plug-in structure, in particular provided by the coding and/or connection structure.
  • the cable can be designed to have a plug-in structure on the cut surface even after cutting. This has the advantage that the cable can be connected directly to the component after it has been cut to a desired length. This is made possible in particular by the plug-in structure being provided continuously or repeatedly in the axial direction along the cable.
  • the cut cable can therefore, as such and thus also immediately after cutting, already have the necessary structure on its cut surface to enable direct connection to the component.
  • the cable is provided with (at least) one contacting surface at which the respective conductor is accessible for contacting with the associated contact means, and at which the coding is preferably provided.

  • the conductor(s) can be adjacent to the outside of the cable or protrude from the interior and be visible from outside the cable.
  • the respective conductor preferably protrudes relative to the contacting surface or is located in a recessed position in the cable.

This provides an easy-to-connect structure, through which the cable can inherently be designed as a plug or socket.
  • the respective contact means is designed to be inserted, preferably pierced, at and/or through the exposed conductor cross-section of the associated conductor.
  • each of the contact means can be inserted into a designated conductor cross-section.
  • the respective conductor, with its (respective) exposed conductor cross-section and the contact means inserted, preferably pierced, therein can be at least partially surrounded by an insulating sheath.
  • the special design of the cable according to the invention has the advantage that when connecting the cable to the component, there is no need to first strip the cable in a complex process and, for example, use crimp connectors to connect a plug-in connector to the cable. Instead, it may be possible for the component to be connected directly to the cut cable, since the cable already has a structure, preferably a plug-in structure and/or coding, for mechanical and/or electrical contacting at the cut surface.
  • the conductors of the cable can also be designed in such a way that they already provide a favorable contacting surface at the cut surface. This is made possible in particular by stranded wires with a diameter that allows a contact means to be inserted and/or pierced into each of the strands.
