Electrical cable for connection to an electrical component

Abstract

The invention relates to an electrical cable (2) for connection with an electrical component (20), wherein the cable (2) has at least one electrical conductor (4).

Description

[0001] The present invention relates to an electrical cable according to the type defined in the preamble of claim 1. Furthermore, the invention relates to a component, a connection system and a method. State of the art

[0002] It is known from the state of the art that electrical cables are used pre-assembled during the installation of an electrical system or that they are only cut to the desired length in the field. However, the use of pre-assembled cables is inflexible and may be limited by the availability of the appropriate cables. Field assembly, on the other hand, is more flexible but often a complex process.

[0003] To assemble the cable, the cable can first be stripped and crimped, then connected to a connector. A crimping tool, for example, is used to securely connect the connector to the cable conductors through pressure and deformation. A stripping tool may also be used to cut off the outer insulation of the cables without damaging the underlying conductors.

[0004] Furthermore, it is known from the state of the art that current Ethernet technology is often too complex and over-dimensioned for applications in the Industrial Internet of Things (IIoT). In particular, conventional connectors and cables are often less than optimal for use at the field level. This complicates the integration of sensors and other components, particularly due to the cabling requirements and limited cable lengths. A simplified Ethernet standard, Single Pair Ethernet (SPE), already offers a solution here through the combination of long cable lengths, compact design, and robust cabling.

[0005] However, conventional solutions are still very complex when it comes to always providing the correct cable length in the field.

[0006] It is therefore an object of the present invention to at least partially remedy the disadvantages described above. In particular, it is an object of the present invention to further simplify installation technology and to provide the correct cable layout for an application in an improved manner. In particular, the aim is to provide an improved, more flexible, and / or simpler connection technology that can be used in the field. Disclosure of the invention

[0007] The invention relates to a cable having the features of claim 1, a component having the features of claim 7, a connection system having the features of claim 13, and a method having the features of claim 14. Further features and details of the invention emerge from the respective subclaims, the description, and the drawings. Features and details described in connection with the cable according to the invention naturally also apply in connection with the component according to the invention, the connection system according to the invention, and the method according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to each other.

[0008] The invention particularly relates to a cable, preferably an electrical one, for connecting to a component, preferably an electrical one. The component is, for example, a connector or a device such as a sensor or actuator or a fieldbus module.

[0009] For example, a connector of type M8, M12, or RJ45 can be used as a connector. Furthermore, the connector can be designed as a substantially cylindrical (such as M8, M12) or rectangular (e.g. RJ45) connector. Furthermore, the connector can have a diameter, in particular a maximum diameter, in the range of 1 mm to 30 mm, preferably 2 mm to 20 mm, more preferably 5 mm to 14 mm. Specifically, the diameter can be substantially 8 mm for M8 and substantially 12 mm for M12. The diameter can refer in particular to the outer diameter of a thread of the connector, which is used for attachment to a device. The cable, in turn, can have an outer diameter in the range of 1 mm to 30 mm, preferably 2 mm to 20 mm, more preferably 3 mm to 10 mm. For M12 cables, for example, the diameters can vary in the range of 4 mm to 6 mm.

[0010] Furthermore, it is possible for the cable to be designed as a power, data, or hybrid cable. As a hybrid cable, the individual cable can, for example, serve for both power and data transmission. For this purpose, one or more data lines and one or more power lines are provided. The respective line, in particular data and / or power line, can have an electrical conductor which is surrounded by a sheath, in particular an insulating sheath or shield. The shield can be made of an electrically conductive material, for example to shield against electromagnetic interference. Materials such as copper or aluminum can be used for this purpose. In contrast, the insulating sheath can be made of an electrically insulating material. Materials such as ceramic, glass, or plastics can be used for this purpose.The respective data line can be designed as an electrical or optical data line and preferably as a fieldbus and / or Ethernet line.

[0011] The component, and in particular the connector, can serve to establish a reliable and secure connection with the cable, particularly for an application in the field of automation technology. This can make it possible to receive electrical current for power transmission and / or signals for data transmission and / or at least one other medium from the cable and / or to transmit them further to a device.

[0012] The component can have at least one or more contact means, each of which can be electrically and / or mechanically contacted with an assigned (associated) conductor of the cable, preferably to establish the connection between the cable and the component. For a reliable and complete connection, if the cable has multiple conductors, the component can or should also be provided with multiple contact means, and the contact means can be electrically and / or mechanically connected to the conductors. In other words, an associated contact means can be provided for each conductor of the cable to be contacted, which contact means is connected accordingly to the associated conductor. The assignment between contact means and conductor can, for example, be based on a predetermined assignment.It can be provided that only one contact means is connected (contacted) with exactly one associated conductor until all contact means of a component have each been contacted with an associated conductor in order to completely establish the connection.

[0013] The respective contact element can be designed as an electrical contact element, i.e., electrically conductive, and the respective conductor can be designed as an electrical conductor. When connecting the cable to the component, the pin assignment of the contact elements can be observed, i.e., the contact elements are connected to the designated conductors of the cable. The pin 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.

[0014] 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 in the cable. Each of the electrical conductors can particularly preferably be designed as a stranded wire. A stranded wire is understood in particular to be an electrical conductor comprising thin individual wires and therefore easy to bend, which is made predominantly of copper, for example. The individual wires can be enclosed by a common insulating sheath (insulation); in this case, this line with the conductor can also be referred to as a stranded wire.

[0015] Furthermore, 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. Furthermore, 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. 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.

[0016] 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, 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 thus 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, enables optimized signal transmission and power supply by ensuring compatibility. The arrangement of the contact elements with the conductors can, for example, refer to the spatial arrangement, e.g., according to the assignment, i.e., a predetermined configuration, so that the "correct" contact elements (especially a contacting movement) contact the "correct" conductors.

[0017] The connection between the component and the cable can be made directly at a contacting surface and, in particular, a cutting surface of the cable. The contacting surface can designate 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 surface can be arranged orthogonally to the axial direction of the cable. The respective conductor of the cable can, at the contacting surface, directly border an outer region of the cable and can 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 flush with the contacting surface. The cable can be designed to provide such a contacting surface after the cable has been cut to size.

[0018] 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. This is to be understood in particular that 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. This is made possible in particular by the fact that the respective conductor (for contacting) has an exposed conductor cross-section, in particular once the cable has been cut to size. Alternatively or additionally, 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).

[0019] The coding can be provided directly on the cable (and thus not or not only on the connector). In particular, 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. According to the invention, 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.

[0020] While mechanical coding preferably involves systematically predetermining 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.

[0021] It is possible for the cable according to the invention to have a coding and / or a connecting structure that 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. Furthermore, 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. In other words, the connecting structure can have a structural section that is repeated in the axial direction of the cable.

[0022] The coding or the connecting structure, specifically the structural section and / or the plug-in 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. Furthermore, 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.

[0023] The coding or connection structure, in particular, makes it possible to significantly reduce 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.

[0024] It is possible for the cut cable to have a plug-in structure, in particular provided by the coding and / or connection structure. In other words, 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.

[0025] Furthermore, within the scope of the invention, it is conceivable for the cable to be 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. Accordingly, the cable can also be designed so that, after cutting, it has a contacting surface, preferably with the coding, at the cutting surface. At the contacting surface or cutting plane, the conductor(s) can be adjacent to the outside of the cable or protrude and be visible from outside the cable. Furthermore, the respective conductor is preferably protruding relative to the contacting surface or is located in a recessed position in the cable.It is also conceivable for any exposed conductor cross-section to also be located in the cutting plane. This provides an easy-to-connect structure, allowing the cable to be inherently configured as a plug or socket.

[0026] Furthermore, it is advantageous if the respective contact means is designed to be inserted, preferably pierced, on and / or through the exposed conductor cross-section of the associated conductor. In other words, if there are multiple conductors, each of the contact means can be inserted into a conductor cross-section provided for it. Furthermore, the respective conductor with its (respective) exposed conductor cross-section and the contact means (respective) inserted, preferably pierced, therein can be at least partially surrounded by an insulating sheath. Thus, no stripping - i.e. removal of the insulating sheath - of the conductor is necessary to make the connection. This simplifies and speeds up cable installation.

[0027] 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 contact at the cut surface. The conductors of the cable can also be designed in such a way that they already provide a favorable contact 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 strand.

[0028] It is also advantageous if 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. In this case, the at least one cavity can be provided for a pin or the at least one guide cavity (for guidance) 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 concrete 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. In other words, 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 if the component is correctly aligned. Furthermore, the at least one cavity can have a length that is designed to correspond to the length of the pin that is inserted into the respective cavity.It is also conceivable that a plurality of cavities form a grid on the contacting and / or cutting surface of the cable, which are arranged in such a way that the at least one contact means and / or the at least one pin of the component can only be introduced there in the correct orientation of the component.

[0029] It is further possible for the or at least one further cavity, and in particular a guide cavity, to be designed for transmitting a fluid, preferably for transmitting a medium such as air or a liquid. Accordingly, 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. In other words, the coding can also transmit a medium that differs from electrical energy. This enables a diverse use of 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.

[0030] According to a further possibility, the at least one coding can comprise a geometric and / or extruded profile of the cable and / or a hose and / or a grommet. In particular, 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.

[0031] Furthermore, 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.

[0032] It is also possible for the mechanical and / or geometric coding and / or the profile to be subsequently applied to the cable, e.g., by means of a guiding 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, for example, also be guided within the cable. This enables simple production of the coded cable. Furthermore, the coding can be arranged in the cable, in particular within a cable sheath of the cable (i.e., in particular in the channel formed by the cable sheath), and / or outside the cable sheath.

[0033] Furthermore, 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 defined by the cable sheath. In other words, the coding may be a structure specifically provided on the cable, which is specifically intended for the purpose of enabling the specific arrangement and / or assignment as described above.

[0034] The cable may optionally further include a grommet. The grommet may have a specific profile, e.g., a particular square or round 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.

[0035] Furthermore, within the scope of the invention, it is conceivable that 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 such 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 for the contact means of the component, i.e. the component must have a corresponding counter coding so that the connection is possible. This ensures that the contacts are correctly electrically connected.

[0036] It is also advantageous if 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.

[0037] For the connection and preferably for introducing the respective contact means, i.e. in particular for plugging and / or piercing, a mechanical force can be exerted on the cable or conductor in the axial direction of the cable (i.e. longitudinal direction of the cable) or the conductor. In particular, this can trigger a contacting movement of the component and / or the cable. However, 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 introduce this contact means into an associated (assigned) conductor or to insert this guide pin into at least one cavity in 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 applied longitudinally along the cable to insert / pierce the contact elements into the conductors, thus causing the contacting movement. This process can also be referred to as "piercing," but unlike conventional solutions, it is not applied laterally along the cable, but rather axially at the cable's cut surface.

[0038] Furthermore, a recurring marking can be provided that indicates the penetration depth of the electrical contact means, preferably in the form of piercing means. The marking can be provided, for example, on the outside of a cable sheath, e.g., printed on it. The marking can be repeated at fixed intervals along the length of the cable in order to provide an indication, starting from the cut surface, of the depth to which the contact means have been correctly inserted after the cable has been severed. This allows the connection to be made even more simplified and reliable. The marking can also assist in orienting the cable for the connection.

[0039] The invention also relates to a component, in particular an electrical component, for connecting to a cable, in particular an electrical cable, preferably a cable according to the invention. The component can have at least one contact means, in particular an electrical contact means, in order to make contact, in particular an electrical contact, with at least one, in particular an electrical, conductor of the cable in the axial direction of the cable or conductor. Furthermore, the at least one contact means can be designed to make contact in, i.e. in particular within, the cable(s) and / or the conductor of the cable. The component according to the invention therefore offers the same advantages as have been described in detail with reference to a cable according to the invention. In contrast to conventional solutions, the connection is simplified in that the contact is not made outside the cable, e.g.by stripping the cable, but rather within the cable and / or the conductor. An additional step such as stripping is therefore not required. Accordingly, contacting within the cable can be understood as the contact being made within a cable sheath and / or cable insulation and / or in a conductor sheath and / or in a conductor of the cable. Contacting within the conductor can be understood as the contact being made by inserting the contact element into the conductor.

[0040] It is conceivable that the component further includes: a counter-coding in order to specify a specific arrangement and / or assignment of the at least one electrical contact means with the at least one electrical conductor of the cable during the connection, wherein the counter-coding can be designed to be complementary to a coding of the cable, and / or the at least one contact means in each case in the form of a piercing means which is designed to penetrate into an associated electrical conductor of the cable in the form of an electrical strand in the axial direction of the cable orof the conductor, preferably to be inserted into an exposed conductor cross-section of the associated electrical conductor, and / or a safety contact means which is designed to lead the at least one (further) contact means, and / or at least one guide pin which is designed to provide axial guidance during the connection, preferably of the component in the cable and / or the cable, wherein the guide pin is preferably designed to lead the at least one contact means.

[0041] The guide pin can be designed to protrude further from the component than the other contact elements. This ensures that the guide pin comes into contact with the cable before the other contact elements, especially as the component approaches a cutting surface of the cable.

[0042] Furthermore, several, preferably at least three or at least four or at least five, contact means can be provided, each of which electrically contacts an associated conductor of the cable. The cable can thus have the corresponding number of corresponding conductors. The conductors and / or the contact means can be arranged at different (in particular lateral) distances from one another in order to form a coding of the cable or a complementary counter-coding of the component. The counter-coding can furthermore be formed by the profile of a pin, i.e. a profile element such as a guide pin and / or a nose, of the component, which can match exactly the cavity coding in the cable.

[0043] In a further embodiment, it can be provided that at least one of the contact means is designed as a safety contact means which is designed in advance of at least one or all of the other contact means in order to preferably contact one of the electrical conductors of the cable before at least one or the other of the contact means when the connection is established. In other words, the safety contact means can be designed in advance in that it protrudes further from the component than the other contact means. The safety contact means thus comes into contact with the cable before the other contact means, in particular as soon as the component comes closer to a cutting surface of the cable. The safety contact means can preferably be designed as a protective conductor and / or earthing conductor.

[0044] It is also advantageous if a sealing means is provided to create a seal between a cable sheath of the cable and the component during assembly to establish the connection. The sealing means can, for example, be a possibly elastic plastic element of the component, which at least partially surrounds the contacting and preferably cutting surface of the cable after the connection.

[0045] Within the scope of the invention, it can be provided that the component is designed as a connector or a sensor or an actuator or a module, e.g., a fieldbus module, preferably for use in industrial automation, preferably in an electrical system for industrial automation. The fieldbus module serves, for example, to transmit data and / or receive control commands via a fieldbus and to be connected to at least one device such as a sensor and / or actuator in order to read the sensor and / or control the actuator.

[0046] The cable according to the invention can further be designed as an Ethernet cable, preferably a Single Pair Ethernet (SPE) cable. The cable can also be provided as a power and / or signal and / or data cable and / or fieldbus cable and / or hybrid cable, i.e. preferably also a combination of the aforementioned cables. In particular, it is possible for the cable to be a combination of data and power cable, in which, in addition to data, electrical power can also be transmitted. For example, the hybrid cable can combine at least fieldbus lines and power lines (e.g., 24 V). It is conceivable that, in addition to electrical signals such as power and data, other media such as air or liquid can also be transmitted through the cable. Furthermore, the maximum cable length can exceed 100 m. The cable can provide a simple connection technology that can be used in the field, in which the cable can be cut to the required length, e.g.,can be unwound from a cable drum and cut. Due to the described structure, and in particular the coding, the cable can be plugged in directly after cutting without further measures such as crimping. A sealant can also provide automatic sealing and strain relief. Strain relief can optionally also be provided by a mechanical locking mechanism, which, for example, cuts into the cable sheath during closing and / or has a force-fitting clamp.

[0047] The connection system according to the invention can have strain relief, which ensures that the connection between the cable and the component is not accidentally released, in particular that the component is not accidentally pulled out of the cable. The strain relief can be provided by a mechanical locking mechanism that, when establishing the connection, cuts into the cable sheath and / or creates a frictional clamp with the cable sheath and / or the conductors of the cable. This holds the cable firmly to the component and prevents accidental separation of the connection. Accordingly, the strain relief can be provided as a function or device of the connection system, which serves to fix and protect the cable to the component and to prevent the cable connection from being damaged by tensile loads.

[0048] If the connection needs to be released again, this can be done using a - preferably tool-free - release mechanism. The connection technology required for this on the component side can, for example, be integrated directly on a circuit board of the component or into a connector of the component. It is also possible for the tool-free release mechanism to be activated by a simple hand movement, which further simplifies operation of the component. For this purpose, the tool-free release mechanism can, for example, have a release tab or a release button formed on the housing of the component to enable easy release without tools. The locking mechanism can be implemented by a latching device that is activated by turning or pressing on a specific area of ​​the component.The locking device can have one or more locking lugs that engage in corresponding recesses or cutouts. The release mechanism can then be implemented by a release button or a release lever, which, with a simple actuation, releases the locking device and releases the connection. Alternatively, the release mechanism can be implemented by a strain relief, which is released by a simple twist or pressure on a specific point on the cable or component. This releases the connection, allowing the cable to be removed.

[0049] Furthermore, the connection system and in particular the component can have a plurality of contact means that establish an electrical connection between the conductors of the cable and electrical contacts of the component. The electrical contacts serve, for example, for energy and / or data transmission to a device such as a sensor or actuator, to which the component can be connected for this purpose. The contact means can be designed as plug contacts and / or needles or other suitable connecting elements. The connection system can also have a protective device that protects the contact means from damage caused by external influences such as dust, dirt, or moisture. For this purpose, a protective cap, a seal, or another suitable protective device can be provided that shields the contact means from harmful environmental influences.

[0050] Furthermore, the at least one or more contact means of the component can be designed to be introduced, preferably pierced, on and / or through an exposed conductor cross-section of an associated conductor of the cable. In this case, the respective conductor with its exposed conductor cross-section and the contact means introduced, preferably pierced, therein can be at least partially surrounded by an insulating sheath and in this way form a line, preferably a stranded line. It can be provided that for contacting, the cable is designed to provide a contacting surface after cutting to size, in which the conductor cross-section is, preferably completely, exposed.

[0051] Furthermore, all or at least one or at least two of the conductors or lines of the cable can be surrounded by at least one shield, in particular individually or in pairs. Pairwise shielding of wire pairs within the cable is particularly useful for hybrid cables and / or for data lines. Contacting the shield can then be achieved, for example, using a contact surface of the component that is axially immersed in the cable. This can have the advantage of achieving greater transmission reliability and lower electromagnetic interference on the individual conductors. It is possible for the conductors or lines of the cable to be shielded from a conductive material such as copper or aluminum. This ensures high conductivity and achieves effective shielding against external interference.

[0052] One option for contacting the shielding is preferably to use a contact surface that penetrates axially into the cable and thus ensures an effective connection with the shielding. For this purpose, the contact surface can be designed, for example, as a conductive coating on the component in order to establish a direct connection with the shielding. Alternatively, the contact surface can also be designed as a separate unit that is inserted into the component and then connected to the shielding. It is also possible to design the contact surface as a spring contact that presses through the shielding and thus creates a reliable connection. The spring contact is, for example, attached to the housing and can therefore be pushed through an opening in the shielding to create a reliable connection.The shielding can extend over the entire length of the cable or only over certain sections, depending on the application requirements. It is also possible for the shielding to consist of multiple layers to achieve even greater shielding effectiveness.

[0053] The cable can be used, for example, for industrial automation, for example, to control tensioning devices or as a drag chain cable in drag chains. Therefore, cables that are particularly suitable for withstanding high mechanical loads and exhibit high flexibility to meet the requirements of industrial automation can be used. Furthermore, they must be highly resistant to environmental influences such as moisture, oil, and chemicals to ensure reliable control of pneumatic tensioning devices or as a drag chain cable in drag chains. Examples of these include cables made of polyurethane (PUR), polyvinyl chloride (PVC), ethylene propylene diene monomer (EPDM), or polyolefin (PO).

[0054] The invention also relates to a connection system comprising a cable—in particular according to the invention and / or an electrical cable—and a component—in particular according to the invention and / or an electrical component. Thus, the connection system according to the invention offers the same advantages as those described in detail with reference to an electrical cable according to the invention and a component according to the invention.

[0055] The invention also relates to a method for electrically contacting a cable, in particular a cable according to the invention and / or an electrical cable, with a component, in particular a cable according to the invention and / or an electrical cable. The method can comprise unwinding and / or fabricating and / or cutting the cable to a desired length. This can create a contacting surface and, in particular, a cutting surface of the cable, at which at least one conductor of the cable becomes accessible for contacting.Furthermore, the method can comprise establishing a direct connection between the component and the cable, wherein the connection can be established directly between at least one contact means of the component and a respective associated conductor of the cable, and / or wherein for this purpose the component (at least parts of the component such as the contact means) is directly inserted and / or pierced into the cable or vice versa in order to establish electrical and / or mechanical contact. In this case, for example, the contact means can be pierced into an associated conductor and preferably into an exposed conductor cross-section of the conductor of the cable. The method according to the invention thus brings with it the same advantages as have been described in detail with reference to a cable according to the invention and a component according to the invention. The simple assembly of the cable can reduce the effort required for its use.This also prevents loops from forming and saves material.

[0056] According to an advantageous development of the invention, it can be provided that a mechanical seal between the cable and the component is also created at least partially or exclusively by establishing the connection. For this purpose, the component can have a sealing means which is transferred directly into the correct position for sealing by the mechanical connection without further measures. The sealing means can, for example, comprise a wall and / or a sealing lip. The sealing means can comprise a wall and / or a sealing lip and is transferred directly into the correct position for sealing by the mechanical connection without further measures in order to reliably seal a contact surface of the cable. For this purpose, the sealing means encloses the contact surface of the cable in this position, for example along the circumference.

[0058] In the following figures, identical reference numerals are used for the same technical features, even in different embodiments.

[0059] In Fig. 1 to 10Embodiments of the invention are shown schematically. Specifically, variants of an electrical cable 2 are shown, which serves for connection to an electrical component 20. For this purpose, the cable 2 can have at least one electrical conductor 4. Furthermore, a connection system 1 according to embodiments of the invention is illustrated, which can have the cable 2 and the component 20. The sectional planes AA and GG are marked in the various views.

[0060] In Fig. 1the cable 2 is shown in a state in which it is completely electrically and mechanically connected to the component 20. It can be seen that the contact means 28 are introduced into the cable 20 and in particular into the electrical conductors 4 of the cable 20 in this state in order to establish a secure mechanical and electrical contact. Clearly visible, the contact means 28 have a tip 30 for being inserted into the conductors 4. The component 20 is designed here, for example, as a plug connector, optionally with a threaded screw connection arranged in the area 24, in order to be attached to a connection of a device such as a fieldbus module, actuator or sensor. The cable 2 can therefore be connected to the device for transmitting electrical energy and / or data via the plug connector.

[0061] In contrast to conventional solutions, the design of the cable 2 can significantly simplify the connection between component 20 and cable 2. For this purpose, structural additions to the cable 2 can be made, such as at least one coding 50 spatially formed on the cable 2. In Fig. 1 It can be seen that the cable 2 has at least one cavity 6, which is used to form the Fig. 9 further illustrated at least one coding 50 on the cable 2 is used (cf. e.g. Fig. 9). Such a coding 50 can also be provided on the component 20 and can then be referred to in particular as a counter-coding 27 if it is designed to be complementary to the coding 50 on the cable 2. The coding of the cavity 6 has the effect that a correspondingly counter-coded pin 26, preferably a guide pin 26, can only be introduced into the cavity 6 as a guide means 26 if the alignment of the component 20 with respect to the cable 2 is correct (i.e. according to a key-lock principle). Otherwise, the introduction of the pin 26 into the cavity 6 can be prevented by other parts of the cable 2. This can then also block the establishment of the connection between the cable 2 and the component 20. The coding 50 on the cable 2 can thus specify a specific arrangement and assignment of electrical contact means 28 of the component 20 with the electrical conductors 4 of the cable 2.

[0062] The at least one coding 50 may comprise a mechanical and / or geometric coding 50 of the cable 2, in which a geometric profile 7 extends in the axial direction A of the cable 2. In Fig. 1 and Fig. 9 The profile 7 can be provided by a T-shaped opening of the cavity 6 on the cable 2, and a corresponding T-shaped counter-coding 27 can be provided on the component 20. The cavity 6 can also be designed for the transmission of a fluid, preferably for the transmission of a medium such as air or a liquid. In addition to a T-shaped coding, an L- or Y-coding or other shapes are also conceivable.

[0063] In Fig. 2 a variant of the component 20 in the form of a plug connector is shown, in which a protruding wall 40 is provided for plug mounting 40 (see also Figs. 6 and 7). The wall 40 can, for example, be attached to a circuit board 42 of the component 20 to enable locking and / or anti-twist protection and / or sealing 44 on the cable 2. This wall 40 can optionally have a locking mechanism 22 to enable secure attachment to the cable 2.

[0064] In Fig. 3 and 4 It is further clarified that the cable can have the plurality of conductors 4 in the form of strands, also called stranded conductors. Each of these stranded conductors can have several fine, twisted wires 12, which may be connected by a Fig. 4recognizable insulating layer (insulation). This insulation is made, for example, from materials such as polyethylene or polyvinyl chloride. It can serve to insulate the conductors 4 both from each other and from the external environment. In addition, the insulation can often be color-coded to facilitate identification and wiring. To minimize electromagnetic interference, a shield made of a metal braid or metal foil can be applied around the insulated conductors 4 as filler material 10. Furthermore, an additional inner sheath can be placed around the shield to increase the mechanical stability of the cable 2. Furthermore, the entire cable 2 can have a robust outer sheath 8, which is preferably made from materials such as PVC, PE or thermoplastic elastomer and can have special properties such as flame retardancy or oil resistance.This multi-layer construction enables high flexibility and robustness of the cable 2, making it suitable for a wide range of applications.

[0065] In further optional designs of cable 2, the conductors can be highly flexible and provided with a 360° full shield. This full shield serves to effectively shield against electromagnetic interference (EMC), thus ensuring the integrity of data transmission. Further optional versions include overmolded versions of cable 2 with highly resistant PUR overmolding, which are specifically designed for use in harsh environments. The cables can be designed for self-assembly, i.e., they can be assembled in the field (on-site at the system). This means, in particular, that the cables themselves have the structural adaptations that allow them to be quickly and easily connected and disconnected and adjusted to the desired length. This way, the cables can be quickly adapted or replaced as needed, without the need for special tools or specialist knowledge.

[0066] The electrical conductor 4 can be made of copper or aluminum, for example. Other materials such as gold, silver, carbon fiber, and conductive polymers can also be used as components of the conductor 4, depending on the application. Furthermore, composite materials made from various of these elements can also be used in specialized applications to optimize specific properties such as conductivity, weight, and corrosion resistance.

[0067] Furthermore, the at least one coding 50 can comprise a geometric and / or extruded profile 7 of the cable 2 and / or a hose (not explicitly shown) and / or a grommet. The at least one coding 50 can further comprise an electrical coding 50 of the cable 2, in which a systematic arrangement of the electrical conductors 4 of the cable 2 is provided, so that a specific assignment of the electrical contact means 28 of the component 20 is predetermined for the connection. Fig. 5 a corresponding coding 50 is illustrated, in which the contact means 28 of the component 20 are arranged in a corresponding manner with different lateral distances.

[0068] In Fig. 1 , 2 and 5-8A component 20 for connecting to an electrical cable 2 is shown schematically. The component can have at least one electrical contact means 28 in order to make electrical contact with at least one electrical conductor 4 of the cable 2 in the axial direction A of the cable 2 or conductor 4. The axial direction A, or also referred to as the longitudinal direction of the cable 2, is in Fig. 1 illustrated by a vertical arrow. Furthermore, the at least one electrical contact means 28 can be designed to make electrical contact in the electrical cable 2—that is, in particular, within the sheath 8.

[0069] In Figs. 6 and 7It is further clarified that a further structure, such as a locking and / or orientation structure 60, can be provided, for example, to further simplify the correct alignment of the component 20 with respect to the cable 2 during connection. The structure 60 is formed, for example, as a groove or material recess on the component 20 and / or on the cable 2.

[0070] In Fig. 8 It can be seen that the cavity 6 of the cable 2 can also be interrupted by a connecting part 14. This connecting part 14 can repeatedly interrupt the cavity 6 in the axial direction A of the cable 2. It serves, in particular, to seal off condensate. This has the advantage of preventing moisture from penetrating the cable 2, thus ensuring its functionality. Accordingly, the connecting part 14 can also serve as a sealing element.

[0071] Furthermore, in Fig. 8A locking pin 45 is shown, which can be provided on the contact means 28 to fix the position on the cable 2 after the connection has been established. More generally, a locking device 45 can be provided on the component 20 or on the cable 2 to fix the established connection.

[0072] Further in Figs. 8 and 9 clarifies that the coding 50 may comprise a first coding 51, which is provided by the shape of the cavity 6. This refers in particular to the shape of the Fig. 9recognizable opening of the cavity 6 with the profile 7. Alternatively or additionally, a second coding 52 can be provided, which is provided by the arrangement and / or design of the conductors 4. In particular, the coding can be provided by the design of the stranded wire 4 to the tip 30 of the contact means 28 or, conversely, the counter-coding can be provided by the design of the tip 30 of the contact means 28 to the stranded wire 4. Due to the tip 30, the contact means 28 can be designed accordingly as a needle, which then penetrates a conductor cross-section 5 of the conductor 4 to make contact during the connection (cf. Fig. 13 ). Different lengths of the contact means 28 can also be provided for anticipating, for example, a safety contact means 29.

[0073] In Fig. 8It is further clear that the component 20 can comprise the at least one contact means 28 in the form of a piercing means, which is designed to be pierced into an electrical conductor 4 of the cable 2 in the form of an electrical strand 4 in the axial direction A of the cable 2 or the conductor 4. Fig. 8 the bending apart of the individual wires of the strand 4 at the pin tip 30 is illustrated.

[0074] In Fig. 1It is further illustrated by a dashed line that at least one of the contact means 28 can be designed as a safety contact means 29, which is designed to lead at least one or all of the other contact means 28. Thus, when the connection is established, ie during a contacting movement, the safety contact means 29 can contact one of the electrical conductors 4 of the cable 2 before at least one or the other of the contact means 28.

[0075] In Fig. 10It is shown that a recurring marking 62 can be provided on the cable 2 (e.g., every 5 mm), indicating a penetration depth of the electrical contact means 28, preferably in the form of piercing means. This marking 62 can, for example, be printed. The marking 62 can, for example, be provided in the form of a line or dot. The marking 62 can also be a mechanical marking, which interacts, for example, with an insertion mechanism 80.

[0076] In Fig. 12 According to further embodiments of the invention, a connection system 1 with a component 20 and a cable 2 can be seen. The component 20 can be provided for connection to an electrical cable 2. For this purpose, the component 20 can comprise several contact means 28 for contacting conductors 4 of the cable 2. In the electrical cable 2 shown, the conductors 4 can be accessible from the outside for contacting the contact means 28. In Fig. 12 the conductors 4 are surrounded by an insulating sheath 11 and are thus part of cables 13, specifically stranded cables 13 (see Fig. 13 ). Both the contact means 28 and the conductors 4 are electrically conductive.

[0077] Furthermore, the conductors 4 can each have an exposed conductor cross-section 5 for contacting (see Figs. 13 and 14 ).

[0078] The connection system 1 can be designed to contact the contact means 28 with the conductors 4 in the axial direction A of the cable 2 or conductor 4 in order to electrically connect the contact means 28 directly to the exposed conductor cross-sections 5. For this purpose, as in Fig. 13 As illustrated, the contact means 28 each have a tip 30 and / or are needle-shaped. In other words, the conductors 4 can be contacted by the contact means 28 being pierced through the exposed conductor cross-sections 5 in the axial direction A.

[0079] Among other things in the Fig. 12 to 14 A contacting surface 9 is provided on the cable 2, at which the conductors 4 are accessible for contacting with the contact means 28. Specifically, the contacting surface 9 can be located in a cutting plane of the cable 2, which has been created, for example, by cutting the cable 2 at this point. It can be seen that the conductors 4 extend from the interior of the cable 2 to the outside (see Figs. 13 and 14 ) or can stand out (see Fig. 12 ) and are therefore visible and accessible from outside the cable 2. In Figs. 13 and 14 the respective exposed conductor cross-section 5 is also in the cutting plane.

[0080] According to Fig. 13 the conductors 4 can each form a line 13 with a surrounding insulating sheath 11, wherein the lines 13 protrude from the contacting surface 9 (see Fig. 12 ) or flush with it ( Figs. 13 and 14). Furthermore, the solution according to embodiments of the invention can avoid stripping, so that the protruding conductors 4 and / or the exposed conductor cross-sections 5 continue to be completely or partially surrounded by the insulating sheath 11. However, the protruding conductors 13 can be at least partially or completely freed from a cable sheath 8 of the cable 2 over their entire circumference (see Fig. 12 ).

[0081] The connection system 1 can be Fig. 12illustrated guide device 70, which is formed separately from the cable 2 and the component 20 and / or is movably or detachably connected to the cable 2 and / or the component 20. The guide device 70 can be designed to mechanically guide the contact in the axial direction A of the cable 2, and preferably to guide the conductors 4, in particular the lines 13, and / or the contact means 28 for contact in the axial direction A of the cable 2. In other words, the guide device 70 can provide a linear guide for the cable 2 and / or the component 20. If the component 20 and the cable 2 move linearly guided relative to one another for contact, this can also be referred to as a contact movement.

[0082] The guide device 70 may comprise a guide housing 72 with a guide structure 71. The guide structure 71 is in Fig. 12specifically in the form of openings of the guide housing 72 in order to provide the mechanical guidance for the respective conductors 4, in particular lines 13, and / or contact means 28. The guide structure 71 can be designed as shown in Fig. 12 shown to receive the conductors 4, in particular lines 13, on a first side 76 of the guide housing 72 and to receive the contact means 28 on another, opposite (and facing away from the first side 76) second side 77 of the guide housing 72.

[0083] The lines 13 in Fig. 12 can have different colors and thus be color-coded. Corresponding colors can also be provided in the area of ​​the openings 71 to facilitate identification.

[0084] Furthermore, at least one coding 50 or counter-coding 27 with the properties as described above can also be provided on the guide device 70, e.g. in the form of a guide sleeve.

[0085] A part 44 of the component 20 and / or the guide device 70 in Fig. 12 In the connected state, it can seal the contact surface 9 and / or mechanically lock it and / or provide anti-twist protection. For example, an O-ring or a sealing lip on the guide device 70 is conceivable as a sealing element. A locking lug or a locking hook (not explicitly shown) can serve as a locking element. A projection or a groove can serve as anti-twist protection.

[0086] In Figs. 15 and 16By way of example, an insertion mechanism 80 is shown, which can be arranged on the guide structure 71 for controlling the contacting movement in order to insert the at least one or more electrical contact means 28, each with a predetermined penetration depth 90, into the associated electrical conductor 4 in an axial direction A of the conductor 4 and / or the cable 2.

[0087] The insertion mechanism 80 can be designed to insert, in particular to pierce, the respective contact means 28 in a linear manner by the contacting movement into the associated electrical conductor 4 with the predetermined penetration depth 90, in particular puncture depth 90, wherein the predetermined penetration depth 90 is preferably in the range from 0.5 mm to 10 mm, preferably 1 mm to 6 mm, preferably 2 mm to 4 mm.

[0088] The insertion mechanism 80 can further comprise a pressure element 81 and a transmission arrangement 82. The transmission arrangement 82 can be connected to the pressure element 81 in a force-transmitting manner in order to set the pressure element 81 in motion when force is applied manually or mechanically to the transmission arrangement 82. Thus, the pressure element 81 can insert, preferably pierce, the respective electrical contact means 28 into the associated electrical conductor 4 via the contacting movement. A travel path 93 for the pressure element 81 between a starting position 91 and an end position 92 can be determined by the predetermined penetration depth 90 and / or be structurally predetermined.Furthermore, an adjustment mechanism 84 can be provided in order to adjust the predetermined penetration depth 90 and preferably the travel path 93 in the insertion mechanism 80, preferably depending on a cable type of the cable 2 and / or continuously and / or in several predefined steps.

[0089] In addition, Fig. 15 schematically illustrates that the insertion mechanism 80 can be designed as a lever mechanism 80, in which a transmission arrangement 82 comprises a lever arm 82. This can serve to transfer a manual or mechanical force exerted on the transmission arrangement 82 into the controlled contacting movement, in which the control is carried out in such a way that the contacting movement is guided linearly and / or the penetration depth 90 is predetermined and / or controlled and / or limited and / or the predetermined and / or a current penetration depth 90 is indicated to a user.

[0090] Furthermore, a Fig. 15 illustrated indexing device 83 may be provided to visually, haptically or acoustically indicate a current penetration depth 90 during the contacting movement.

[0091] In Fig. 16It is shown that the insertion mechanism 80 can further comprise a nut 85, preferably a union nut 85, which is designed to establish a mechanical connection between the component 20 and the cable 2 and for this purpose is screwed onto a thread 86. Furthermore, a transmission arrangement 82 can be provided, which is designed to transmit a movement, in particular a rotational movement, of the nut 85 on the thread 86 to a pressure element 81. Furthermore, the pressure element 81 can be arranged and guided in the region of a guide space 87 in order to move through the guide space 87 of the guide structure 71 through the transmitted movement along a longitudinal axis of the thread 86 in order to thereby exert a force for inserting the electrical contact means 28, wherein the guide space 87 is designed to receive a part of the component 20 and / or the at least one electrical contact means 28.

[0092] Furthermore, according to Fig. 16 a holding element 88 may be provided which is firmly connected to the pressure element 81 in order to limit the contacting movement when the holding element 88 encounters a counter-holding element 89.

[0093] In Fig. 11 A method 100 for electrically contacting a cable 2 with a component 20 is schematically visualized. According to a first step 101, the cable 2 can be unwound and / or prepared to a desired length. According to a second step 102, a direct connection can be made between the component 20 and the cable 2. For this purpose, the component 20 can be directly inserted and / or pierced into the cable 2, or vice versa, in order to establish electrical and mechanical contact. Furthermore, a mechanical seal between the cable 2 and the component 20 can be established, at least partially or exclusively, by establishing the connection.

[0094] The above explanation of the embodiments describes the present invention exclusively by way of examples. Of course, individual features of the embodiments can be freely combined with one another, provided they are technically feasible, without departing from the scope of the present invention.
