  • 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, particularly a cross-section of the cable.
  • the contacting surface can refer to a surface, particularly 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 surface can be arranged orthogonally to the axial direction of the cable.
  • the respective conductor of the cable can be directly adjacent to an outer region of the cable at the contacting surface and thus be connected to the contact means of the component without severing the sheath and/or insulation of the cable.
  • the respective conductor can also 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 respective conductor is or becomes accessible from the outside (i.e. outside the cable), in particular that it can be electrically contacted from the outside without further measures such as stripping.
  • 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 connecting structure in particular the coding and/or the plug-in structure and/or the profile, can extend over substantially the entire or predominant length of the cable and/or can be provided continuously and/or repeatedly.
  • the connecting structure can have a structural section which is repeated in the axial direction of the cable.
  • the coding or the connecting structure can comprise at least one or more or exactly one cavities, preferably each in the form of a channel.
  • a part of the component such as a respective guide pin, can optionally be plugged into the cavity or one or each of the cavities.
  • 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 contacting surface can lie in the cutting plane of the cable. In other words, the contacting surface can lie at the plane at which the cable was cut.
  • the cable can also be designed such that, after cutting, it has a contacting surface, preferably with the coding, at the cutting surface.
  • 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. It is also conceivable that a respective exposed conductor cross-section also lies in the cutting plane. 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.
  • the at least one coding comprises a mechanical and/or geometric coding of the cable, in which a geometric profile, in particular a spatial shape and/or contour, extends in the axial direction of the cable, e.g., is arranged continuously or repeatedly.
  • the profile can define at least one cavity and, in particular, a guide cavity, preferably the spatial shape and/or contour of the cavity.
  • the at least one cavity can be provided for a pin, or the at least one guide cavity (for guidance) can be provided for a guide means such as a guide pin of the component, so that a specific orientation of the component (relative to the cable) is predetermined for the connection and/or, in the event of a deviation from the specific orientation, the connection of the component to the cable is blocked.
  • the specific orientation can also be predetermined by the specific shape of the at least one cavity, e.g., by the shape of the wall and/or the opening formed by the wall.
  • the opening can, for example, have a rectangular or trapezoidal shape that corresponds to the shape of the pin, in particular the guide pin. This ensures that the component or pin is inserted in exactly the right position and is not crooked or twisted.
  • the opening of the cavity can be shaped such that the at least one contact means and/or the at least one pin of the component can only be inserted therein when the component is correctly aligned.
  • the at least one cavity can have a length which is designed according to the length of the pin which is inserted into the respective cavity.
  • a plurality of cavities to form a grid on the contacting and/or cutting surface of the cable, which cavities are arranged such that the at least one contact means and/or the at least one pin of the component can only be inserted therein when the component is correctly aligned.
  • the or at least one further cavity, and in particular a guide cavity can be designed for transmitting a fluid, preferably for transmitting a medium such as air or a liquid.
  • the cable can serve not only for transmitting electrical energy, but optionally also for transmitting the fluid, e.g. a medium such as air or a liquid.
  • the coding can also be used to transmit a medium other than electrical energy. This enables a diverse range of uses for the cable.
  • the cable can therefore be designed not only as an electrical cable, but alternatively or additionally also as an air and/or liquid conduction cable.
  • the at least one coding is a geometric and/or extruded profile of the cable and/or a hose and/or a grommet.
  • the mechanical and/or geometric coding can be provided by the cable having a specific geometric profile.
  • the specific geometric profile can be provided, for example, by the shape of at least one cavity and/or an opening of a cavity in the cable.
  • boundaries such as cable walls can be provided, which, for example, form the opening and the cavity.
  • the boundaries can be arranged and shaped to create the specific geometric profile.
  • the boundaries are made of plastic, for example.
  • the boundaries and/or the profile can advantageously be extruded directly onto the cable, e.g., by forming the boundaries and, in particular, walls within the cable.
  • the mechanical and/or geometric coding and/or the profile can be subsequently applied to the cable, e.g., using a guide device and/or a grommet, preferably a guide grommet, and/or a hose.
  • the grommet can be attached to the cable from the outside.
  • the hose can also be guided within the cable, for example. This enables simple production of the coded cable.
  • the coding can be arranged in the cable, in particular within a cable sheath (i.e., in particular in the channel formed by the cable sheath), and/or outside the cable sheath.
  • a form of coding may deviate from the (particularly original, geometric) basic shape of the cable, preferably the cylindrical basic shape of the cable, such as a cylindrical structure predetermined by the cable sheath.
  • the coding may be a structure specifically provided on the cable, which is provided on the cable specifically for the purpose of enabling the specific arrangement and/or assignment as described above.
  • the cable may optionally further include a grommet.
  • the grommet may have a specific profile, e.g., a particular square or rounded shape, which provides the coding.
  • the grommet may also serve to insulate and mechanically protect the electrical conductors within the cable.
  • the grommet may be made of a high-temperature-resistant material such as polyethylene or silicone and be designed to provide optimal strain relief for the conductors contained within the cable. Furthermore, the grommet may be provided with a special coating that minimizes electrical conductivity and thus reduces the risk of short circuits.
  • the grommet may further include one or more chambers that serve to separate the individual conductors from one another, thus improving electrical insulation and/or (through the shape and/or arrangement of the chambers) providing the coding.
  • the at least one coding comprises, as an alternative or in addition to the mechanical and/or geometric coding, an electrical coding of the cable, in which a systematic arrangement of the electrical conductors of the cable is provided, so that a specific assignment of the electrical contact means of the component is predetermined for the connection.
  • This can be understood to mean that the conductors of the cable have a predetermined arrangement in which the conductors have different (in particular lateral) distances from one another according to a coding specification. These differences must also be provided accordingly in the contact means of the component, i.e. the component must have a corresponding counter coding to enable the connection. This ensures that the contacts are correctly electrically connected.
  • the electrical conductors of the cable are each designed as a stranded wire in order to form a receptacle (in particular in the axial direction of the conductor) for introducing at least one electrical contact means of the component, preferably for inserting and/or piercing the respective contact means in the form of a contacting tip, in particular in the axial direction of the cable and/or at a contacting surface.
  • the design as a stranded wire has the advantage that the stranded wire can have several individual wires which, due to their flexibility, can provide better accommodation for the contact means. In particular, the mechanical deformability of the individual wires can therefore be exploited during the connection in order to introduce the contact means into the stranded wire and to obtain reliable contact when inserting/piercing the contact means.
  • a mechanical force can be exerted on the cable or conductor in the axial direction of the cable (i.e., the longitudinal direction of the cable) or the conductor. In particular, this can trigger a contacting movement of the component and/or the cable.
  • a leading contact means and/or a (possibly also leading) guide pin of the component can first be applied to the cut surface of the cable in order to then insert this contact means into an associated (assigned) conductor or to insert this guide pin into at least one cavity of the cable. In this process, the further contact means of the component finally touch the conductors of the cable at the cut surface.
  • the force can then be exerted in the longitudinal direction of the cable to insert/pierce the contact means into the conductors and thus effect the contacting movement.
  • This process can also be referred to as "piercing,” although this In contrast to conventional solutions, this is not done laterally on the cable, but axially on the cutting surface of the cable.
  • a recurring marking is provided which indicates a penetration depth of the electrical contact means, preferably in the form of piercing means.
