Description

Technical Field

[0001] The present invention relates to a guide device. In addition, the present invention relates to a connection system and method. Background Art

[0002] It is known from the state of the art that cables are used pre-assembled during the installation of electrical systems, or are only assembled on site to the desired length. However, the use of pre-assembled cables is inflexible and may be limited by the availability of the corresponding cables. On the other hand, on-site assembly is more flexible, but is usually a time-consuming process.

[0003] To assemble the cable, the cable may first be stripped and crimped and then connected to the plug connector. A crimping tool, for example, is used to securely connect the plug connector to the cable conductor by applying pressure and deformation. The stripping tool may also be used to cut the outer insulation of the cable without damaging the conductor underneath.

[0004] It is also known from the latest technology that current Ethernet technology is often too complex and oversized for use in the Industrial Internet of Things (IIoT). In particular, in many cases, conventional plug connectors and cables are not optimal for use in the field. This makes the integration of sensors and other components more difficult, especially due to cabling requirements and limited cable lengths. The simplified Ethernet standard Single Pair Ethernet (SPE) has provided a solution here by combining long cable lengths, compact design and durable cabling.

[0005] However, traditional solutions are still expensive when it comes to always having the correct cable length available in the field. Summary of the invention

[0006] The object of the present invention is therefore to at least partially eliminate the above-mentioned disadvantages. The object of the present invention is in particular to further simplify the installation technology and to provide the correct cable length for the application in an improved manner. In particular, an improved, more flexible and / or simpler connection technology that can be used in this field is to be provided.

[0007] The objects of the invention are a guide device and a connection system. Further features and details of the invention are apparent from the description and the drawings. Features and details described in conjunction with the guide device according to the invention naturally also apply to the connection system according to the invention and to the method according to the invention, and vice versa, so that reference is made to each other with regard to the disclosure or to individual aspects of the invention.

[0008] The object of the present invention is in particular a guide device for helping to form an electrical connection between a component and a cable. In particular, this can be understood to mean that a contact movement, in particular a linear contact movement, is guided so as to contact the respective conductor of the cable and the contact mechanism of the component associated with the conductor. This can be obtained, for example, by a relative movement of the conductor and the contact mechanism relative to each other. The relative movement refers in particular to a relative movement of the relative movement conductor and the contact mechanism relative to each other, during which at least one of the two components is moved. The contact movement can cause the respective contact mechanism to contact the relevant conductor and thus establish an electrical connection. The electrical connection can be further improved and / or fixed by moving and guiding the respective contact mechanism further into the relevant conductor. The further movement can also be part of the contact movement and can therefore be guided by the guide device.

[0009] The guide device can have a guide housing which is preferably at least partially electrically insulating. In addition, the guide device can have a guide structure which is formed on the guide housing to guide the contact movement so that at least one or more electrical contact means of the component can contact the relevant (i.e. assigned) electrical conductor of the cable. For example, the guide structure can have at least one opening and / or at least one channel and / or the like, through which a linear guidance of the respective conductor and the contact means can be achieved.

[0010] In addition, the guide device can be designed to clearly define a specific arrangement and allocation of multiple electrical contact mechanisms relative to multiple electrical conductors during contact. In particular, this means that the "correct" contact mechanism is connected to the "correct" relevant conductor. To this end, the guide device can, for example, have a spatially formed coding. Coding can preferably be understood to refer to the systematic shaping and / or arrangement of contact points and / or mechanical parts to ensure a specific connection configuration when contact is formed. The arrangement can refer to the orientation of the components relative to the cable. The allocation can refer to the allocation of each contact mechanism to one of the conductors to which it is assigned (i.e., related), especially according to a predetermined allocation of conductors or contact mechanisms. The allocation of contact mechanisms to conductors especially implies a mutual allocation, i.e., the conductors are allocated to the contact mechanisms.

[0011] In addition, an insertion mechanism can be provided, which is arranged on the guide structure for controlling the contact movement, so that the at least one or more electrical contact mechanisms are inserted into the relevant electrical conductors with a predetermined penetration in the axial direction of the conductor and / or cable. Here, the following mechanism can be provided, which allows the contact mechanism to be inserted, in particular pierced, into the conductor in an assisted or automated manner. This can have the following advantages, facilitating the operation of the guide device and thus obtaining a higher accuracy in connecting the cable to the component. The contact movement can be controlled mechanically, but alternatively or additionally, electronic control such as sensor-assisted control can also be used.

[0012] Preferably, it can be provided that the insertion means are designed to insert, in particular pierce, the respective contact means which are linearly guided by the contact movement into the associated electrical conductor with a predetermined penetration depth, in particular a piercing depth, wherein the predetermined penetration depth is preferably in the range of 0.5 mm to 10 mm, preferably 1 mm to 6 mm, preferably 2 mm to 4 mm. This ensures that the insertion or piercing is carried out correctly.

[0013] For example, it can be provided that the insertion mechanism also has a pressure piece and a transmission assembly. The transmission assembly can be connected to the pressure piece in a force-transmitting manner so that the pressure piece is set in motion when a force is applied manually or mechanically to the transmission assembly. This allows the respective electrical contact mechanism to be introduced, preferably inserted, into the relevant electrical conductor via the contact movement through the pressure piece. In addition, the movement path of the pressure piece between the starting position and the final position can be determined by a predetermined penetration depth and / or can be predetermined by the structure. Predetermined by the structure means in particular that the arrangement, shape and / or composition of the guiding device is defined in such a way that a penetration depth is obtained and / or the insertion is limited to the penetration depth.

[0014] It is further optionally provided that an adjustment mechanism is provided to adjust the predetermined penetration depth and preferably the stroke in the insertion mechanism, preferably depending on the cable type of the cable and / or continuously and / or in several predetermined steps. This can have the advantage that the insertion mechanism can be adapted to different types of cables to ensure an optimal penetration depth and stroke. This allows a reliable and efficient cable installation. The adjustment mechanism can also be automatically or manually operated and an indexing device is provided to monitor the set conditions. This allows the operator of the insertion mechanism to quickly and easily adjust the set conditions to ensure an accurate and reliable cable installation.

[0015] Preferably, provision can be made for the insertion mechanism to be designed as a lever mechanism, in which case the transmission component comprises a lever arm in order to transmit a force applied manually or mechanically to the transmission component into a controllable contact movement, in which the contact movement is preferably controlled in such a way that the contact movement is linearly guided and / or the penetration depth is predetermined and / or controlled and / or limited and / or preset and / or the penetration depth is indicated to the user, for example via a display device.

[0016] It is also advantageous if an indexing device, preferably a display device, is provided in order to indicate, in particular to display, the current penetration depth visually or tactilely or acoustically during the contact movement, the indexing device being preferably designed as one of the following:

[0017] a visual scale showing the current penetration depth, preferably by means of markings for different positions along the stroke of the pressure piece of the insertion mechanism, for example by printing a scale on the guide housing,

[0018] - a locking mechanism, wherein locking elements are provided at various positions so as to provide tactile feedback to the operator of the guide device when the pressure element reaches various positions,

[0019] - a click mechanism or snap mechanism that provides audible feedback when the pressure piece reaches the various positions,

[0020] - a device having mechanical resistance elements at various locations,

[0021] - A device having magnetic position marks at various locations.

[0022] It is also conceivable that the insertion mechanism also has a nut, preferably a union nut, which is designed to establish a mechanical connection between the component and the cable and is screwed onto the thread for this purpose. A transmission assembly can also be provided, which is designed to transmit the movement, in particular the rotational movement, of the nut on the thread to the pressure piece. The pressure piece can be arranged in the guide space area of ​​the guide device and guided so that it can move through the guide space of the guide structure by the transmission movement along the longitudinal axis of the thread to apply a force in order to insert the electrical contact mechanism. The guide space can be designed to accommodate a part of the component and / or the at least one electrical contact mechanism. The guide space can be adapted to the size of the cable for this purpose.

[0023] Optionally, the insertion mechanism may also include a pressure piece for directly or indirectly transmitting force to the electrical contact mechanism so as to insert it into the relevant electrical conductor through a contact movement. In addition, a retaining member may be provided, which is firmly connected to the pressure member to limit the contact movement when the retaining member encounters a corresponding retaining member. The corresponding retaining members, in particular other corresponding retaining members preferably spaced apart, may preferably be arranged along the cable axial direction so as to visually and mechanically mark the predetermined penetration depth. This may have the following advantages, and the penetration depth may be visually checked quickly and easily without the need for a special measuring instrument. In addition, the preferred spacing arrangement of the corresponding retaining members may also help to ensure that the cable remains in place at a predetermined position in a consistent and stable manner. This in turn may help to ensure that the cable does not slip or become damaged during operation.

[0024] A further advantage may be that the guide device is designed to predetermine a specific arrangement and allocation of multiple electrical contact mechanisms relative to the electrical conductor during contact, wherein the guide structure is designed to guide the contact movement in the form of a linear relative movement of the electrical contact mechanism and the electrical conductor relative to each other during contact. To this end, the guide structure can, for example, have a spatial boundary for the conductor and the contact mechanism, in which the conductor and / or the contact mechanism are guided separately or together. Linear guidance can be obtained by arranging the respective conductors in a straight line with the relevant contact mechanism (and / or the respective contact mechanism with the relevant conductor) and holding and guiding it on this line through the spatial boundary. For example, based on a predefined electrical allocation, these conductors are allocated to the contact mechanism. In this regard, in particular in relation to the connector, the electrical allocation can be understood to mean that each contact mechanism meets a specific electrical function and is therefore allocated to a specific conductor. The guide device can help ensure that the conductor is not connected incorrectly and that the component and in particular the plug connector works properly.

[0025] Furthermore, it can be provided within the scope of the invention that a guide structure is formed on a first side of the guide housing for mechanically guiding the electrical conductor. To this end, the guide structure can, for example, include an opening on the first side of the guide housing. The guide structure can be formed on a second side of the guide housing for mechanically guiding the electrical contact mechanism. To this end, other openings can be provided on the second side of the guide housing in order to guide the electrical conductor and the electrical contact mechanism toward each other from different sides, so that preferably the guiding of the contact is provided in the inner space of the guide housing. This may have the advantage that the contact movement can be easily and safely carried out in the guide housing. To this end, the interior can be designed to have a size and shape that is adapted to the shape and size of the cable and preferably the diameter.

[0026] It can be preferably provided within the scope of the invention that at least one coding is formed spatially on the guide housing in order to predetermine a specific arrangement and distribution of the electrical contact means relative to the electrical conductors. The at least one coding can include a mechanical coding and / or a geometric coding, in which a geometric profile, in particular a spatial shape and / or an outer shape, extends through the guide device. Preferably, the profile can define a guide bore for a guide mechanism, preferably a guide pin of a component and / or a cable. This has the effect of predetermining a specific orientation of the component and / or cable for contact. In addition, it can be achieved that the components and / or cables are prevented from moving relative to each other in the event of deviation from a specific orientation. In particular, a contact movement can thus be prevented.

[0027] The at least one coding can be formed spatially by a geometrical profile and / or an extruded profile comprising a guide and / or a tube. Particularly preferably, the guide bore is designed to transport a fluid, in particular a medium such as air or a liquid. For example, the profile can be formed on the cable during an extrusion process.

[0028] It is also conceivable that at least one coding is provided on the guide housing, whereby the at least one coding comprises an electrical coding and / or a color coding, in which a systematic arrangement of the electrical conductors is specified. This has the advantage that a specific allocation of the electrical contact means is predetermined for the contacting. The allocation can relate to a specific connection arrangement in which the electrical contact means are contacted in a specified sequence.

[0029] The connection system may comprise an insertion mechanism, in particular a screw mechanism, a lever mechanism or a plug mechanism to perform the contact movement, the insertion mechanism preferably being designed to move the cable towards the component during the contact movement, the guide or insertion mechanism preferably comprising an adjustment mechanism for adjusting the predetermined penetration depth of the contact mechanism for inserting the conductor at the insertion mechanism, preferably depending on the cable type of the cable and / or continuously and / or in several predetermined steps, wherein the guide or insertion mechanism preferably comprises an index or indexing device, which is suitable for indicating the current penetration depth to the user during the contact movement. The insertion mechanism may be the aforementioned insertion mechanism.

[0030] The screw mechanism is preferably designed as a union nut or comprises a union nut, which establishes an electrical connection when screwed onto the component. The lever of the lever mechanism can preferably be mounted on the component. The actuation of the lever can cause the contact movement. The component preferably comprises a thread, preferably an external thread, such as an M8 or M12 thread, and the union nut comprises a matching thread, preferably an internal thread.

[0031] The insertion mechanism may comprise, for example, a clamping jaw. The insertion mechanism or the clamping jaw may be part of the component, attached to the component or independent of the component. The clamping jaw may clamp a cable or a cable end, preferably in this case the clamping jaw clamps or holds the cable or the cable end. For this purpose, the clamping jaw preferably interacts with a strain relief contour and / or a coding of the cable, preferably in this case the clamping jaw is clamped behind a protrusion or engaged in a recess. The clamping jaw preferably has a coping coding. In other words, the cable can only be clamped by the clamping jaw in the intended orientation in order to establish a given electrical connection between the cable and the component, in particular between the cable electrical conductor and the contact mechanism of the component.

[0032] Preferably, the insertion mechanism can be used not only to establish an electrical connection, but also to establish a required surface pressure for a seal, especially an elastomeric seal, on the component. The seal can be arranged so that it is in physical contact with the contact surface when the electrical connection is formed. The seal can be produced by a multi-component injection molding process during the component manufacturing process. The seal can seal the transition between the conductor and the contact mechanism and / or the fluid conduit and / or the liquid channel from the contact point, and / or seal the contact surface relative to the connection system environment. Through the insertion mechanism, the cable held and / or limited by the clamping jaws can be moved toward the component, so as to preferably establish an electrical connection between the cable and the component, especially between the cable conductor and the contact mechanism. The insertion mechanism is designed so that the contact mechanism can only be contacted by piercing the cable conductor at the contact surface.

[0033] The index can be designed as a scale or as an acoustic and / or tactile feedback to the user. For example, the locking noise of the locking mechanism caused by the contact movement may cause such an acoustic feedback. It is also conceivable that a coupling mechanism or the coupling of the coupling mechanism during the contact movement generates a tactile feedback. For this purpose, a scale can be formed on the component, and the insertion mechanism, in particular a screw mechanism, a lever mechanism or a plug mechanism, can preferably serve as a pointer to the scale.

[0034] The adjustment mechanism can be designed as an adjustable movement limiter of the insertion mechanism, in particular a screw mechanism, a lever mechanism or a plug mechanism, which preferably limits the maximum penetration depth or maximum puncture depth of the contact mechanism into the conductor. The adjustment mechanism can be adjustable, for example, by means of a screw or a union nut and / or a rotary movement. Preferably, the insertion mechanism has a motion converter, which can be designed to convert or convert an actuation movement, in particular a push movement or a rotary movement or a pivoting movement, into a contact movement.

[0035] It can be provided within the scope of the invention that the guide device is designed as a guide grommet for a cable. The guide grommet is characterized in particular by the fact that it fixes the cable in a defined alignment and / or contains the cable from damage. For this purpose, the guide grommet can be made of a flexible material, such as rubber or plastic, and have an inner guide groove which reliably and stably holds the cable.

[0036] Another object of the invention is a connection system comprising:

[0037] - a component for connection to an electric cable, wherein the component comprises at least one or more contact means for each making contact with an associated conductor of the cable, wherein the respective contact means is designed to be electrically conductive,

[0038] - a cable, wherein the respective associated conductor is accessible for easy contact, wherein the respective conductor is designed to be electrically conductive, and wherein the respective conductor has an exposed conductor cross section,

[0039] - A guide device for supporting the respective contact mechanism in contact with the relevant conductor, the guide device having a guide housing designed to be at least partially electrically insulating, the guide device having a guide structure designed on the guide housing to guide the contact movement of the respective conductor and / or the respective contact mechanism for contact.

[0040] The guide device may also have an insertion mechanism which is arranged on the guide structure for controlling the contact movement so as to insert the respective contact mechanism into the associated electrical conductor in the axial direction of the conductor and / or cable at a predetermined penetration depth.

[0041] The connection system according to the invention thus has the same advantages as those described in detail with reference to the guide device according to the invention.

[0042] It is also possible that the connection system for making the respective contact mechanism contact the relevant conductor is designed in the axial direction of the relevant conductor to electrically connect the respective contact mechanism directly to the exposed conductor cross section of the relevant conductor. For this purpose, the contact mechanism can be inserted into the conductor cross section in the longitudinal direction of the conductor, for example. Alternatively or additionally, the at least one coding can be formed by a cable cross section without rotational symmetry, in particular the inner shape and / or outer shape of a cable without rotational symmetry. The respective exposed conductor cross section can be completely exposed in the cross section, for example, cut through. The non-rotationally symmetrical outer shape can be formed by the outer peripheral surface of the cable sheath or the cable, preferably in the following manner, the cross section of the cable has a circular basic shape and at least one recess, in particular a groove and / or at least one protrusion, in particular a flange. The recess or protrusion, in particular the flange is preferably a coding. Alternatively, the outer shape can be a free shape or a polygonal shape. The inner shape can be formed by a circular fluid line, which forms a coding due to its position and / or shape in the cable cross section. Alternatively, the fluid line can have a free shape or a polygonal shape. Due to the coding, the component with the coding can be regarded as a key, and the component with a matching corresponding coding can be regarded as a lock. This ensures the intended specific contact between the conductor and the contact mechanism.

[0043] According to a further advantage, it can be provided that the respective contact means has a pointed tip and / or is needle-shaped so that the relevant conductor can be contacted by piercing the contact means at the location of the in particular completely exposed conductor cross section and / or through the exposed conductor cross section. In particular, piercing includes a contact movement, in which a force can be applied to the contact means to produce an opening or a passage in the conductor cross section.

[0044] Also can design respective conductor as stranded wire, it has soft single wire so that conductively surrounds the contact means inserted through respective conductor cross section, especially pierced.Do like this advantage is to provide flexible seat for contact means by single wire, thus make insertion simple.

[0045] According to another possible solution, it can be provided that the respective means are designed to be inserted, preferably pierced, into the conductor at and / or through the exposed conductor cross section, wherein at least the respective conductor with its exposed conductor cross section and the contact means inserted, preferably pierced therein are surrounded by an insulating sheath and / or a shield. This can have the advantage that the respective conductor, in particular the data conductor for sensitive data transmission, is protected from external influences such as electromagnetic interference or mechanical damage. In addition, the insulating sheath and / or the shield can also help to protect the conductor from moisture and corrosion, which can extend the service life of the cable and increase its reliability.

[0046] The electrical conductors of the cable can be twisted together, in particular in the form of one or more twisted pairs, twisted threes or twisted fours, wherein the at least one coding can have a continuous course along the length of the cable and / or a course that matches the twist, so that at any point along the length of the cable the at least one coding and the electrical conductor can have the same relative position to each other, in particular in a plane that is transverse to the direction of extension of the cable, preferably perpendicular to the direction of extension of the cable. In other words, the coding on the cable sheath can have a continuous spiral course in the direction of extension of the cable, preferably with a constant pitch, which is particularly matched to the twist. The coding can be in the form of a recess, in particular a notch or groove, or a protrusion, in particular a shoulder or flange. Twisting can reduce electromagnetic interference. By twisting the conductor, The induced electromagnetic fields significantly cancel each other out, reducing susceptibility to interference. However, this changes the position of the conductor along the length of the cable, making contact between the component contact mechanism and the cable conductor more difficult. This problem can be solved by coding and a prescribed constant relative position of the coding along the cable relative to the conductor, and the expected contact between the component contact mechanism and the corresponding conductor of the cable can be achieved at any point in the cable because the coding can have a continuous direction that matches the twist. The various strands can be spaced apart and / or evenly distributed in the cable cross-section. If the cable has a fluid pipeline, it is preferred that the strands are evenly arranged around the fluid pipeline in order to best obtain uniform cooling of the conductors or strands.

[0047] The cable can have a fluid line, in particular a liquid line or a gas line, wherein in particular the at least one coding can be formed partially or only by the fluid line, wherein the electrical conductor, in particular the strand or strands, surround the fluid line along the cable extension range so as to preferably ensure that the conductor is uniformly cooled by a fluid that can be guided through the fluid line, wherein the component can have a fluid channel, which can be connected to the fluid line of the cable in a transmission fluid manner and in particular can partially or only form a corresponding coding. Preferably, the fluid line and / or the fluid channel contribute to the coding by the shape of its cross section, in particular transverse to or perpendicular to the direction of extension of the cable and / or by its position in the cable cross section, which is transverse to or perpendicular to the direction of extension of the cable. The contribution to the coding can, for example, mean that the geometry of the cable sheath or the cable shape also contributes to the coding. In other words, the geometry of the cable sheath or the cable shape together with the fluid line, in particular the shape and / or position of the fluid line, can form the coding. Alternatively, preferably only the fluid line forms the coding by the shape of its cross section, in particular transverse to or perpendicular to the direction of extension of the cable and / or by its position in the cable cross section, which is transverse to or perpendicular to the direction of extension of the cable.

[0048] The cable can have a plurality of profiles, in particular strain relief profiles, preferably in the form of circumferential recesses, in particular grooves or notches, or protrusions, in particular flanges or steps, preferably for a heat shrink tube or strain relief, along its outer circumference, preferably at orderly intervals from one another, and wherein the component can have a strain relief for the cable, in particular a heat shrink tube designed as a strain relief, which is preferably attached to the component, the strain relief being matched with the strain relief profile of the cable in such a way that the cable is strain relieved, in particular by forming a strain relief that matches the shape of the strain relief profile of the cable, preferably by engaging behind or in the strain relief profile. The strain relief is preferably designed in such a way that the strain relief pre-tensions the cable to the component, preferably in the direction of cable extension and / or in the contact direction. In addition, the strain relief can include a clamping jaw arm for rear-side engagement or rear clamping. The strain relief can be made of plastic and / or integral with the component. The strain relief can also be adjustable, so that the pre-tensioning of the cable to the component can be adjusted. The pre-tensioning can be distributed or continuously adjustable. The strain relief device may preferably be designed such that it establishes a strain relief connection with the strain relief device profile during the contact movement to establish an electrical connection between the cable and the component.

[0049] Preferably, an electrical connection can be established between the cable and the component, in particular by inserting a contact mechanism into the relevant conductor, the connection system comprising a seal, in particular a material connection and / or a force-fitting and / or form-fitting seal, which seals the connection and in particular a cable section adjacent to the connection relative to the environment of the connection system, in particular according to IP20 or IP67, wherein the seal can preferably be formed by a heat shrink tubing or a heat shrink tubing forming a strain relief device, in particular in the case of a form-fitting seal. For example, such a form-fitting seal can be made with a heat shrink tubing. IP20 may be a protection and / or certification, which indicates protection against the ingress of foreign bodies. IP67 may be a protection and / or certification, which indicates protection against dust and water resistance for up to 30 minutes at a maximum depth of 1 meter underwater. Preferably, IP20 and IP67 refer to protection levels and / or certifications that come into effect on September 27, 2024, in particular in the Federal Republic of Germany.

[0050] The seal can be formed by a sealing compound, in particular an adhesive or a potting compound, whereby, in particular in the direction of extension of the cable and / or perpendicularly to the direction of extension of the cable, a sealing cavity can be formed between the cable, in particular the cable contact surface and the component to accommodate the sealing compound, the sealing compound being located in the sealing cavity and preferably completely filling the sealing cavity, wherein the sealing cavity can preferably have a filling opening for the sealing compound, the filling opening can be closed in particular by the sealing compound, wherein the sealing cavity can preferably have an outlet hole for the sealing compound agent, the outlet hole can be closed in particular by the sealing compound, wherein the section of the component defining the sealing cavity is in particular formed by a transparent material, so that the extent to which the sealing cavity is filled with the sealing compound can be visually determined. The sealing compound can be filled into the sealing cavity in a liquid state through the filling opening. Through the outlet hole, the excess sealing compound filled can escape from the sealing cavity in a liquid state, so that it can be determined whether the sealing compound is evenly distributed in the sealing cavity. The sealing compound is preferably curable and / or electrically insulating. Closing the opening with a sealing compound prevents foreign matter or moisture from entering the sealing cavity.

[0051] The seal can be formed by releasing the filling of the microcapsules, in particular the cable or the component. The filling of the microcapsules can preferably be released by providing heat, providing radiation and in particular light preferably in the form of UV light, contact with an activating substance or providing light in combination with moisture.

[0052] The seal can seal and / or electrically insulate the transition from the fluid line to the fluid channel in a fluid-tight manner relative to a contact point formed by the conductor contacting a contact means on a contact surface, and / or wherein the seals electrically insulate and / or seal the contact point formed by the conductor contacting a contact means on a connection surface. In this way, fluid leakage or failure is prevented.

[0053] The seal can be formed by a heat shrink tube, whereby the heat shrink tube is preferably designed as a strain relief for the cable, because the heat shrink tube forms a form fit, in particular with the strain relief profile of the cable, preferably because the heat shrink tube engages behind or in the strain relief profile and is attached to the component by attachment of the component, in particular the attachment profile of the component, thus preferably forming a pretensioning of the cable to the component. Alternatively, it is conceivable that the heat shrink tube is used only as a seal.

[0054] The contact mechanism can be energized to the electrical contact conductor of the plug assembly or the socket assembly of the component, whereby the position and / or arrangement and / or distribution and / or size setting of the electrical contact conductor is different from that of the contact mechanism, particularly on the contact surface. Preferably, a plug with such a plug assembly or a socket with such a socket assembly can be formed on the component. The guiding path of the contact conductor from the contact mechanism to the plug or the socket can preferably not be straight, but tilted at least at one point of the path, preferably tilted vertically, or curved, whereby the plug or the socket is formed on one side of the component transverse to or perpendicular to the insertion direction or contact direction of the cable. The plug can be designed to establish an electrical and / or form-fitting connection with the socket. The socket can be designed to establish an electrical and / or form-fitting connection with the plug. Alternatively, the plug or the socket can be formed on the side of the component, which is facing away from the side of the component where the cable can be electrically contacted with the contact mechanism. In addition, the guiding path of the contact conductor from the contact mechanism to the plug or the socket is designed so that the arrangement and / or distribution of the electrical conductor of the plug or the socket is different from that of the contact mechanism. For example, an electrical connection can be made from a small cable cross section of a cable to a large plug assembly or socket assembly. Preferably, the distance between at least two contact conductors of the socket assembly or plug assembly in the cable cross section is greater or less than the distance between the cable electrical conductors in the cable cross section.

[0055] The electrical conductor can preferably extend only and / or directly to and / or abut against a contact surface of the cable or said contact surface, preferably in such a way that a contact means, in particular in the form of a contact tip and / or a piercing means, can penetrate into the electrical conductor at the contact surface, wherein the contact surface preferably extends transversely, in particular perpendicularly, to the direction of extension of the cable, and wherein the contact surface can in particular be a cutting surface of the cable and / or a cable end of the cable, at which the cable has preferably been shortened to the desired length. Preferably, the contact surface can be formed by cutting at any point along the extension of the cable, in particular if the coding extends over the entire length of the cable. Preferably, the contact means is designed so that the electrical conductor of the cable can only be pierced by the contact means, in particular without cutting.

[0056] According to another possible solution, it can be provided that the respective conductor forms a wire with the surrounding insulating sheath. If a plurality of conductors are provided, the wires can be color-coded, in particular by means of different colors of the insulating sheaths. It may then be advantageous to use corresponding corresponding codings on the guide means in order to color-code the guide structure and preferably the opening of the guide housing with respect to the corresponding wire. This can have the advantage of facilitating the installation and maintenance of the cable, since the color coding allows for quick identification of the cable.

[0057] It is also advantageous that the cable conductors are each designed as strands to form a receptacle for inserting, preferably piercing, the associated contact means of the component into the strands. A guide device may be provided between the cable and the component in order to guide the insertion, preferably piercing, with a predetermined arrangement and distribution of the contact means of the component and the cable conductors.

[0058] Another object of the invention is a method for forming a connection between a cable and a component, comprising the following steps:

[0059] - providing a connection system, in particular according to the invention, having a cable and a component and a guide, wherein the component comprises at least one or more contact means each for contacting an associated conductor of the cable, wherein the conductor cross section of the respective conductor is exposed and accessible from the outside,

[0060] - inserting the respective contact means through the exposed conductor cross section of the relevant conductor in order to establish contact between the contact means and the conductor, wherein the insertion is linearly guided by means of a guide device and wherein the insertion is controlled by means of an insertion mechanism in such a way that the respective contact means is inserted into the relevant conductor to a predetermined penetration depth in the axial direction of the conductor and / or cable.

[0061] The method according to the invention thus has the same advantages as those described in detail with reference to the guide device according to the invention and / or the connecting system according to the invention.

[0062] Advantageously, the invention can provide that the respective conductor together with the surrounding insulating sheath forms a wire, wherein the cable is provided by cutting it to the desired length without stripping the respective wires, wherein the respective contact means are inserted without first stripping the respective wires.

[0063] The component is, for example, a plug connector or a device such as a sensor or an actuator or a fieldbus module. For example, a plug connector of the type M8 or M12 or RJ45 can be used as a plug connector. In addition, the plug connector can be designed as a plug connector of a substantially cylindrical shape (such as M8, M12) or a rectangular shape (such as RJ45). In addition, the diameter of the plug connector, in particular the maximum diameter, can be in the range of 1mm to 30mm, preferably in the range of 2mm to 20mm, preferably in the range of 5mm to 14mm. Specifically, the diameter of M8 can be substantially 8mm, and the diameter of M12 can be substantially 12mm. The diameter can especially refer to the outer diameter of the thread of the plug connector, which is used to connect it to the device. The outer diameter of the cable can be in the range of 1mm to 30mm, preferably in the range of 2mm to 20mm, preferably in the range of 3mm to 10mm. For example, in the case of an M12 cable, the diameter can vary in the range of 4mm to 6mm.

[0064] The cable can also be designed as a power cable, a data cable or a hybrid cable. As a hybrid cable, a single cable can be used for example for power and data transmission. For example, one or more data lines and one or more power lines are provided for this purpose. Each cable, in particular a data cable and / or a power cable, can have an electrical conductor surrounded by a sheath, in particular an insulating sheath or a shield. The shield can be made of a conductive material, in order to, for example, shield electromagnetic interference. Materials such as copper or aluminum can be used here. On the other hand, the insulating sheath can be made of an electrically insulating material. Materials such as ceramics, glass or plastic can be used here. Each data line can be designed as an electrical or optical data line and is preferably designed as a fieldbus and / or Ethernet line.

[0065] This component and in particular the plug connector can be used to establish a reliable and safe connection with a cable, in particular for applications in the field of automation technology. This can allow receiving a current for power transmission and / or a signal for data transmission and / or at least another medium from the cable and / or transmitting it to the device. The component can have at least one or more contact mechanisms, each of which can be electrically and / or mechanically contacted with the assigned (related) conductor of the cable, so as to preferably establish a connection between the cable and the component. In this case, in the case of several conductors of the cable, it can or should be provided that the component has multiple contact mechanisms to achieve a reliable and complete connection, and the contact mechanism can be electrically and / or mechanically connected to the conductor. In other words, a relevant contact mechanism can be provided for each cable conductor to be contacted, and the contact mechanism is therefore connected to the relevant conductor. For example, the distribution between the contact mechanism and the conductor can be carried out according to a predetermined distribution. It can be provided that only one contact mechanism is connected (contacted) to exactly one relevant conductor at a time until all contact mechanisms of the component are in contact with the relevant conductor to complete the connection.

[0066] The respective contact means can be designed as an electrical contact means, i.e. electrically conductive, and the respective conductors can be designed accordingly as electrical conductors. When connecting the cable to the component, the distribution of the contact means can be taken into account, i.e. the contact means are connected to the cable conductors provided for this purpose. The distribution thus defines which conductors are assigned to which contact means. In other words, this depends on the specific arrangement and / or distribution of the component contact means and the cable conductors.

[0067] The cable may have at least one electrical conductor. Preferably, at least two or three or four or more or at most 10 electrical conductors of the cable are provided. Each electrical conductor can particularly preferably be designed as a stranded wire. A stranded wire is particularly understood to be an electrical conductor having thin individual wires and thus being flexible, the individual wires being, for example, mainly made of copper. The individual wires may be surrounded by a common insulating sheath (insulation), in which case such conductors may also be referred to as strands.

[0068] In addition, at least one coding can be provided on the cable. The coding can be formed in a spatial manner on the cable, that is, in particular in a three-dimensional manner. In addition, the coding can be arranged on the contact surface of the cable, in particular on the cutting surface. The coding can be used to clearly define the specific arrangement and / or distribution of the contact mechanism of the component, in particular the electrical contact mechanism and the conductor of the cable, in particular the electrical conductor, preferably for clearly defining and / or guiding the connection. The coding can preferably be understood to refer to the systematic shaping and / or systematic arrangement of the contact points and / or mechanical elements to ensure a specific connection configuration. Therefore, the coding can be used to avoid wrong connections and ensure the correct alignment of the components relative to the cable during the connection process (such as in the form of a plug connector). Therefore, the coding advantageously defines the correct orientation of the components, that is, the correct orientation of the cable (preferably relative to the cable), and achieves optimized signal transmission and power supply by ensuring compatibility between different components.

[0069] The connection between the component and the cable can be made directly at the contact surface. The contact surface can designate a surface, in particular a cross section of the cable, at which the respective conductors of the cable are accessible from the outside in order to come into contact with the contact means of the component. The surface can be arranged orthogonally to the cable axis. The respective conductors of the cable can be in the immediate vicinity of the outer region of the cable at the contact surface of the cable and thus connected to the contact means of the component without cutting through the sheath and / or insulation of the cable. The respective conductors can also be separated at the contact surface flush with the contact surface.

[0070] The cable can be designed in such a way that the respective conductors of the cable are accessible for contacting with the associated contact means. This is to be understood in particular to mean that the respective conductors are accessible from the outside (i.e. outside the cable) and in particular can be electrically contacted from the outside without further measures such as stripping. This is due in particular to the fact that the respective conductors (for contacting) have an exposed conductor cross section.

[0071] The coding can be arranged directly on the cable (so not on the plug or not only on the plug connector). The coding can be formed in particular between areas and / or in areas on the cable and / or through the conductor and / or insulation and / or in or on the cable sheath (e.g. inner sheath and / or outer sheath). Coding is known in plug connectors, in particular by electrical coding, where the contact points are arranged so that only a correct electrical connection is possible. According to the invention, the coding can be transferred to the cable, i.e. alternatively or additionally arranged on the cable, for example in the form of mechanical coding and / or electrical coding. The coding can also be alternatively referred to as a coding structure or a connection structure.

[0072] While coding in the form of mechanical coding preferably involves a systematically predetermined at least one portion of the cable or a special shape on the cable, in the case of electrical coding, the cable conductors can be arranged in such a way that only a correct electrical connection to the component is possible. Producing the coding on the cable can have the advantage of significantly simplifying and speeding up the connection process between the cable and the component. This is due to the fact that the component can be directly and immediately connected to the cable.

[0073] The cable according to the invention may have a coding and / or connection structure extending in the axial direction (longitudinal direction) of the cable and / or the cable conductor. The connection structure may have a coding and / or insertion structure and / or a (geometric) profile. In addition, the connection structure, in particular the coding and / or insertion structure and / or the profile may extend over the substantially entire or main length of the cable and / or be arranged continuously and / or repeatedly. In other words, the connection structure may have a structural part that repeats in the axial direction of the cable.

[0074] The coding or the connection structure, in particular the structural part and / or the insertion structure may comprise at least one or more or exactly one cavity, preferably each in the form of a channel. A part of the component, for example a respective guide pin, may be inserted into the cavity or one or each cavity. The coding may be provided by a special geometric shape (in particular a polygon) of the (respective) cavity. In addition, the coding may also be defined by a plurality of angles and / or sides of such a shape. It is also conceivable that the coding is provided by several of the cavities, for example based on the arrangement and / or size and / or possibly different shapes of the cavities.

[0075] The coding or connection structure can especially significantly reduce the assembly steps required for the connection process between the cable and the component. In addition, even after the cable is cut to length, the cut cable itself may already have the required structure to allow the direct connection of the component.

[0076] The cut cable may have an insertion structure, in particular provided by the coding and / or connecting structure. In other words, the cable may also be designed to have an insertion structure on the cut surface even after the cable has been cut to length. This has the advantage that the cable can be directly connected to the component after cutting to the desired length. This is in particular due to the fact that the insertion structure is continuous or repeated along the axial direction of the cable. Therefore and thus immediately after cutting, the cut cable may already have the necessary structure on its cut surface to allow direct connection of the component.

[0077] It is also conceivable within the scope of the invention to provide (at least) one contact surface on the cable, at which the respective conductor can be approached to contact the relevant contact mechanism, and preferably a coding is provided at the contact surface. The contact surface can be located in the cutting plane of the cable. In other words, the contact surface can be located at the plane where the cable is cut. Therefore, the cable can also be designed to have a contact surface preferably with coding on the cutting surface after cutting. This or these conductors can be adjacent to or protrude from the inside and outside of the cable at the contact surface or cutting plane and can be seen from outside the cable. In addition, the respective conductors preferably protrude from the contact surface or are located in a recessed position in the cable. It is also conceivable that the respective exposed conductor cross-section is also located in the cutting plane. This provides a structure that is easy to connect, which allows the cable to be inherently designed as a plug or socket.

[0078] It is also advantageous if the respective contact means is designed to be inserted into, preferably pierce and / or penetrate the exposed conductor cross section of the associated conductor. In other words, in the case of a plurality of conductors, each contact means can be inserted into the conductor cross section provided for this purpose. Furthermore, the respective conductor with the (respectively) exposed conductor cross section and the (respectively) inserted, preferably pierced contact means can be at least partially surrounded by an insulating sheath. Thus, it is not necessary to strip the conductor, i.e. remove the insulating sheath, in order to make the connection. This simplifies and speeds up the installation of the cable.

[0079] The special design of the cable according to the invention has the advantage that when the cable is connected to the component, it is not necessary to first strip the cable in a complex process and connect the plug connector to the cable using, for example, a crimp connector. Instead, the component can be connected directly to the cut cable, since the cable already has structures, preferably insertion structures and / or coding, for mechanical connection and / or electrical contact at the cut surface. The cable conductors can also be designed such that they already provide a favorable contact surface at the cut surface. This can be achieved in particular by strands whose diameter allows the contact mechanism to be inserted and / or pierced into the strands.

[0080] It is also advantageous that at least one coding comprises a mechanical coding and / or a geometric coding of the cable, wherein the geometric profile, in particular the spatial shape and / or the outer shape, extends in the axial direction of the cable, for example in a continuous or repeated arrangement. The profile may define at least one cavity, in particular a guide cavity, preferably defining the spatial shape and / or the outer shape of the cavity. The at least one cavity may be provided for a pin, or the at least one guide cavity (for guidance) may be provided for a guide such as a guide pin of a component, thereby predetermining a specific orientation of the component (relative to the cable) for the connection, and / or preventing the connection of the component to the cable in the event of a deviation from a specific orientation. The specific orientation may also be predetermined by a specific shape of the at least one cavity, for example by the shape of the wall and / or by the opening formed by the wall. For example, the opening may have a rectangular or trapezoidal shape corresponding to the shape of the pin, in particular the guide pin. This ensures that the component or pin is inserted in the correct position without tilting or twisting. In other words, the opening of the cavity may be shaped to allow at least one contact mechanism of the component and / or at least one pin to be inserted therein only in the correct orientation of the component. In addition, the at least one cavity may have a length corresponding to the length of the pin inserted into the corresponding cavity. It is also conceivable that a plurality of cavities form a grid on the contact surface and / or cutting surface of the cable, which are arranged such that at least one contact means and / or at least one pin of the component can only be inserted therein with a correct orientation of the component.

[0081] It is also possible that the or at least another bore, in particular the guide bore, is designed for transmitting a fluid, preferably a medium such as air or a liquid. Thus the cable can be used not only for transmitting electrical energy, but also optionally for transmitting a fluid, for example a medium such as air or a liquid. In other words, the coding can also be used for transmitting a medium other than electrical energy. This allows the cable to be used in a variety of ways. Thus, the cable can be designed not only as an electrical cable, but also alternatively or additionally as an air cable and / or a fluid cable.

[0082] According to another possible solution, it can be provided that the at least one coding comprises a geometrical profile and / or an extruded profile of the cable and / or the tube and / or the grommet, the coding being arranged in the cable, in particular in the cable sheath of the cable and / or outside the cable sheath and / or on the cable sheath. In particular, the mechanical coding and / or the geometrical coding can be provided by a cable having a specific geometrical profile. For example, the specific geometrical profile can be provided by the shape of at least one bore and / or the bore opening of the cable.

[0083] In addition, boundaries such as cable walls can be provided, which for example form openings and cavities. The boundaries can be arranged and shaped in a way that creates a specific geometric profile. The boundaries are for example made of plastic. The boundaries and / or profiles can advantageously be extruded directly onto the cable, for example by forming the boundaries and in particular the walls in the cable.

[0084] The mechanical coding and / or geometric coding and / or profile can also be subsequently attached to the cable, for example by means of a guide and / or a grommet, preferably a guide grommet and / or a cable sheath and / or a hose. The grommet can be connected to the cable from the outside. For example, the hose can also be guided inside the cable. This can make it easier to produce a coded cable. In addition, the coding can be arranged in the cable, in particular in the cable sheath of the cable and / or outside the cable sheath.

[0085] In addition, the shape of the coding can deviate from the (particularly original geometric) basic shape of the cable, preferably not the cylindrical basic shape of the cable such as the cylindrical structure provided by the cable sheath. In other words, the coding can be a structure specially arranged on the cable, which is arranged on the cable specifically for allowing a specific arrangement and / or distribution as described above.

[0086] The cable may also optionally have a grommet. The grommet may have a specific profile that provides coding, such as a specific square or round shape. The grommet may also be used to insulate and mechanically protect the electrical conductors in the cable. The grommets may be made of high temperature resistant materials such as polyethylene or silicone and designed to provide optimal strain relief for the conductors contained in the cable. Furthermore, the grommets may be provided with special coatings to minimize electrical conductivity and thus reduce the risk of short circuits. The grommets may also include one or more cavities for separating individual conductors from each other, thereby improving electrical insulation and / or providing coding (through the shape and / or arrangement of the cavities).

[0087] It is also conceivable within the scope of the invention that, as an alternative or in addition to the mechanical coding and / or geometric coding, at least one coding comprises an electrical coding of the cable, in which the rational arrangement of the electrical conductors of the cable is specified, thereby predetermining a specific allocation of the electrical contact means of the component for the connection. This can be understood to mean that the cable conductors have a predetermined arrangement in which the conductors are spaced differently from each other (especially in the transverse direction) according to the coding specification. These differences must also be provided in the contact means of the component, i.e. the component must have a corresponding corresponding coding so that the connection can be realized. This ensures that a correct electrical connection is established between the contact points.

[0088] It is also advantageous that the electrical conductors of the cable are all formed as strands in order to form (especially in the axial direction of the conductor) a socket for inserting at least one electrical contact means of the component, preferably a socket for inserting and / or piercing a respective contact means in the form of a contact tip, especially in the axial direction of the cable and / or on a contact surface, wherein on the contact surface the conductor is preferably in the immediate vicinity of the cable outer area. Designing as a stranded wire has the following advantages, the stranded wire can have several single wires, which can provide better accommodation for the contact means due to its flexibility. In particular, the mechanical deformation capacity of the single wire can be used during the connection process in order to insert the contact means into the stranded wire and obtain reliable contact when inserting / piercing the contact means.

[0089] In order to connect and preferably insert the respective contact mechanisms, i.e., in particular to insert and / or pierce, a mechanical force can be applied to the cable and / or conductor in the axial direction of the cable and / or conductor (i.e., the longitudinal direction of the cable). In particular, this may trigger a contact movement of the component and / or cable. However, the pilot contact mechanism and / or the (possibly also pilot) guide pin of the component can first be applied to the cable cutting surface so that the contact mechanism is subsequently inserted into the relevant (distribution) conductor or the guide pin is inserted into at least one cavity of the cable. In this process, the other contact mechanisms of the component eventually contact the cable conductor on the cutting surface. Then, a force can be applied in the longitudinal direction of the cable to insert / pierce the contact mechanism into the conductor and thus cause a contact movement. This process can also be referred to as "piercing", but unlike conventional solutions, this is not done on the cable side, but axially on the cable cutting surface.

[0090] It can also be provided that a recurring mark is provided, which indicates the penetration depth of the electrical contact means, preferably in the form of a piercing means. For example, the mark can be provided on the outer surface of the cable sheath, for example printed on the cable sheath. The mark can be repeated at fixed intervals in the longitudinal direction of the cable, so that after the cable has been cut, an indication of the depth to which the contact means has been correctly inserted is obtained starting from the cut surface. This makes the connection simpler and more reliable. The mark can also help determine the cable orientation for the connection.

[0091] The cable and / or components and / or connection system can be designed for single pair Ethernet (SPE) and / or have only one wire pair / conductor pair. Unlike traditional Ethernet, which usually has four wire pairs or conductor pairs per cable, SPE reduces the demand for cables, resulting in compact and cost-effective connections. Such cables preferably have only one pair of wires or only one pair of conductors. The cable preferably can include the twisting of this pair of wires or this pair of conductors. A single wire pair or conductor pair can be designed to transmit data and current or voltage, preferably at a distance of up to 1000 meters and / or with a maximum data transmission speed of 10Mbps, 100Mbps or 1Gbps. In addition, the cable can be designed to provide current or voltage to a terminal device and transmit data simultaneously according to power over data line (PoDL). The cable and / or components and / or connection system can preferably be used for or be applicable to industry 4.0, Internet of Things (IoT), automotive industry or building automation applications. The conductor pair or wire pair preferably comprises or is composed of copper or a copper alloy. The cable preferably corresponds to a single-pair Ethernet cable according to IEEE 802.3bw, preferably under this standard which comes into force on September 27, 2024, in particular in the Federal Republic of Germany. The cable can preferably be designed for full-duplex communication.

[0092] The component can preferably be a single pair Ethernet plug connector (SPE plug connector) in particular according to the IEC 63171 standard, preferably in accordance with the state of September 27, 2024, in particular valid for the Federal Republic of Germany. Particularly preferably, the component can be designed as a plug connector or a round plug connector with an M8 or M12 thread. The plug assembly or socket assembly of such a plug connector can have a thread for attaching in particular to an electrical device or a sensor. In addition, the cable and / or the component and / or the connection system can be designed for transmitting a maximum power of 50 or 60 watts.

[0093] The conductors are preferably cable conductors unless otherwise specified. In other words, if it is clearly stated that they are conductors of a plug assembly or a socket assembly, they can preferably only be conductors of a plug assembly or a socket assembly.

[0094] The two interacting codes can be referred to as coding and coping coding. BRIEF DESCRIPTION OF THE DRAWINGS

[0181] In the following figures, the same reference numerals are used for the same technical features even for different embodiments.

[0182] Figures 1 to 10 Embodiments of the invention are schematically shown. In particular, a plurality of variants of a cable 2 for connecting to an electrical component 20 are shown. To this end, the cable 2 can have at least one electrical conductor 4. Furthermore, a connection system 1 according to an embodiment of the invention is shown, which can include a cable 2 and a component 20. Section planes AA and GG are marked in the various views.

[0183] exist Figure 1 In the figure, the cable 2 is in a state of being fully electrically and mechanically connected to the component 20 as shown. It can be seen that in this state the contact mechanism 28 is inserted into the cable 20, in particular the electrical conductor 4 of the cable 20 to establish a firm mechanical and electrical contact. It can be clearly seen here that the contact mechanism 28 has a tip 30 to pierce the conductor 4. The component 20 is designed as a plug connector here, which may have a threaded screw connection arranged in the area 24 to attach to a connection mechanism of a device such as a fieldbus module, an actuator or a sensor. This allows the cable 2 to be connected to the device for transmitting electrical energy and / or data via the plug connector.

[0184] Unlike conventional solutions, the cable 2 design can significantly simplify the connection between the component 20 and the cable 2. To this end, a structural addition can be made to the cable 2, such as at least one coding 50 formed in a spatial manner on the cable 2. Figure 1 It can be seen that the cable 2 has at least one cavity 6, which is used to form at least one code 50 on the cable 2, such as Fig. 9 As further shown (see Fig. 9 ). Such a coding 50 can also be provided on the component 20 and is particularly referred to as a counter coding 27 if it is formed complementary to the coding 50 on the cable 2. The coding of the bore 6 means that a corresponding counter-coding pin, preferably a guide pin 26, can only be inserted into the bore 6 as a guide means 26 if the component 20 is oriented correctly relative to the cable 2 (i.e. according to the lock and key principle). Otherwise, other parts of the cable 2 may hinder the insertion of the pin 26 into the bore 6. This can then also prevent the establishment of a connection between the cable 2 and the component 20. Thus, the coding 50 on the cable 2 can clearly specify a specific arrangement and allocation of the electrical contact means 28 of the component 20 and the electrical conductors 4 of the cable 2.

[0185] The at least one coding 50 may comprise a mechanical coding and / or a geometric coding 50 of the cable 2, in which a geometric profile 7 extends in the axial direction A of the cable 2. Figure 1 and Fig. 9 In the embodiment, the profile 7 can be provided by a T-shaped opening of the bore 6 on the cable 2 and a corresponding T-shaped coding 27 can be provided on the component 20. The bore 6 can also be designed for conveying a fluid, preferably a medium such as air or liquid. In addition to the T-shaped coding, L-shaped or Y-shaped coding or other shapes are also conceivable.

[0186] Figure 2 An embodiment of a component 20 in the form of a plug connector is shown, where a protruding wall 40 is provided for the connector assembly 40 (see also Figure 6 and Figure 7 ). The wall 40 can be attached, for example, to a printed circuit board 42 of the component 20 in order to provide a locking device and / or anti-twist protection and / or a seal 44 on the cable 2. The wall 40 can optionally have a locking mechanism 22 to allow a secure attachment to the cable 2.

[0187] Figure 3 and Figure 4 It is further shown that the cable can have a plurality of conductors 4 in the form of twisted wires, which are also called stranded conductors. Each of these stranded conductors can have several thin strands 12, which can be Figure 4 The cable 2 is surrounded by an identifiable insulating layer (insulation). This insulation is made of materials such as polyethylene or polyvinyl chloride, for example. It can be used to insulate the conductors 4 from each other and from the external environment. In addition, the insulation can usually be color-coded for easier identification and routing. In order to minimize electromagnetic interference, a shield made of a metal mesh or a metal foil can be arranged around the insulated conductor 4 as a filler 10. In addition, an additional inner sheath can be placed around the shield to improve the mechanical stability of the cable 2. In addition, the entire cable 2 can have a strong outer sheath 8, which is preferably made of a material such as PVC, PE or a thermoplastic elastomer and can have specific properties such as flame retardancy or oil resistance. This multilayer structure allows the cable 2 to have high flexibility and robustness, making it suitable for a wide range of applications.

[0188] In other optional designs of the cable 2, the conductor can be extremely flexible and equipped with a 360° full shield. This full shield can effectively shield electromagnetic interference (EMC), thereby ensuring the integrity of data transmission. Other optional versions include an overmolded version of the cable 2 with a highly resistant PUR overmolding, which is specially designed for application in harsh environments. The cable can be designed to be self-assembled, that is, assembled on site (on site on the system). In particular, this means that the cable itself has structural adaptability, which allows it to be quickly and easily connected and separated and adapted to the desired length. In this way, the cable can be quickly adjusted or replaced as needed without the need for special tools or expert knowledge.

[0189] The electrical conductor 4 can be made of copper or aluminum, for example. Depending on the application, other materials such as gold, silver, carbon fiber and conductive polymers can also be used as components of the conductor 4. In addition, composite materials made of various of these elements can also be used in special applications to optimize specific properties such as conductivity, weight and corrosion resistance.

[0190] Furthermore, the at least one coding 50 may include the geometry of the cable 2 and / or the extrusion profile 7 and / or the conduit (not explicitly shown) and / or the grommet. The at least one coding 50 may also include an electrical coding 50 of the cable 2, in which a reasonable arrangement of the electrical conductors 4 of the cable 2 is specified, thereby predetermining a specific assignment of the electrical contact means 28 of the component 20 for the connection. Figure 5 , a corresponding coding 50 is shown in which the contact means 28 of the component 20 are arranged in a corresponding manner at different lateral spacings.

The component may have at least one electrical contact mechanism 28 for making electrical contact with at least one electrical conductor 4 of the cable 2 in the axial direction A of the cable 2 or the conductor 4. The axial direction A or longitudinal direction of the cable 2 Figure 1 In addition, at least one electrical contact mechanism 28 can be designed to produce an electrical contact in the cable 2, ie in particular in the sheath 8.

The structure 60 is formed, for example, in the form of a groove or material recess on the component 20 and / or the cable 2.

[0193] Figure 8 The bore 6 of the cable 2 is shown to also be interrupted by a connection 14. The connection 14 can repeatedly interrupt the bore 6 in the axial direction A of the cable 2. In particular, it acts as a seal for condensation. This has the advantage of preventing moisture from penetrating the cable 2, thus ensuring that it is always effective. The connection 14 can thus also act as a seal.

[0194] also, Figure 8 A locking pin 45 is shown which may be provided on the contact mechanism 28 to secure the position on the cable 2 after the connection has been made. More generally, a locking device 45 may be provided on the component 20 or the cable 2 to secure an established connection.

[0195] Figure 8 and Fig. 9 It is further shown that the coding 50 may include a first coding 51 provided by the shape of the cavity 6. This refers in particular to a first coding 51 having a Fig. 9The opening shape of the cavity 6 is the contour 7 which can be recognized in the drawing. Alternatively or additionally, a second coding 52 provided by the arrangement and / or formation of the conductor 4 can be provided. In particular, the coding can be provided here by forming the strand 4 to the tip 30 of the contact means 28, or vice versa, a corresponding coding can be provided by forming the tip 30 of the contact means 28 to the strand 4. Due to the tip 30, the contact means 28 can be designed accordingly as a needle, which then penetrates the conductor cross section 5 of the conductor 4 in order to make contact during the connection process (see Fig.13 ). Different lengths of the contact mechanism 28 can also be provided, for example, for leading the safety contact mechanism 29.

[0196] Figure 8 It is further shown that the component 20 can include at least one contact means 28 in the form of a piercing means which is designed to be penetrated into an electrical conductor 4 in the form of an electrical strand 4 of the cable 2 in the axial direction A of the cable 2 or the conductor 4 . Figure 8 The individual wires of the strand 4 are shown to be bent apart at the pin tip 30 .

[0197] exist Figure 1 It is further shown by dashed lines that at least one of the contact mechanisms 28 can be designed as a safety contact mechanism 29, which is designed to be in front relative to at least one or all other contact mechanisms 28. This allows the safety contact mechanism 29 to contact one of the electrical conductors 4 of the cable 2 before at least one or another of the contact mechanisms 28 when making a connection, i.e. during the contact movement.

[0198] Fig.10 It is shown that recurring markings 62 (e.g., one every 5 mm) can be provided on the cable 2, which indicate the penetration depth of the electrical contact means 28, which is preferably in the form of a piercing means. For example, the markings 62 can be printed thereon. The markings 62 can, for example, be provided in the form of lines or dots. The markings 62 can also be mechanical markings, which, for example, interact with the insertion means 80.

[0199] exist Fig.12 In FIG. 1 , according to a further embodiment of the invention, a connection system 1 having a component 20 and a cable 2 can be seen. The component 20 can be configured to be connected to the cable 2. To this end, the component 20 can include a plurality of contact means 28 for making contact with the conductors 4 of the cable 2. In the illustrated cable 2, the conductors 4 are accessible from the outside for making contact with the contact means 28. Fig.12 In the embodiment, the conductor 4 is surrounded by an insulating sheath 11 and is therefore part of a wire 13, in particular a stranded wire 13 (see Fig.13 ). Both the contact means 28 and the conductor 4 are electrically conductive. Furthermore, the conductor 4 may have an exposed conductor cross section 5 for contacting (see Fig.13 and Fig.14 ).

[0200] The connection system 1 can be designed to make the contact means 28 contact the conductor 4 in the axial direction A of the cable 2 or the conductor 4 so as to electrically connect the contact means 28 directly to the exposed conductor cross section 5. For this purpose, Fig.13 As shown, the contact means 28 can each have a pointed end 30 and / or be needle-shaped. In other words, the conductor 4 can be contacted by piercing the exposed conductor cross section 5 along the axial direction A with the contact means 28 .

[0201] exist Figure 12 to Figure 14 In particular, a contact surface 9 is provided on the cable 2, at which the conductor 4 can contact the contact mechanism 28. Specifically, the contact surface 9 can be located in a cutting plane of the cable 2, which is formed, for example, by cutting the cable 2 at this point. It can be seen that the conductor 4 can approach the outside from the inside of the cable 2 (see Fig.13 and Fig.14 ) or protrusion (see Fig.12 ), so that it is visible and accessible from outside the cable 2. Fig.13 and Fig.14 In the diagram, the respective exposed conductor cross section 5 is also located in the sectional plane.

[0202] according to Fig.13 Each conductor 4 can form a wire 13 with the surrounding insulating sheath 11, whereby the wire 13 extends from the contact surface 9 (see Fig.12 ) or flush with the contact surface 9 ( Fig.13 and Fig.14 ). Furthermore, the solution according to the embodiment of the invention can avoid stripping, so that the protruding conductor 4 and / or the exposed conductor cross section 5 are still completely or partially surrounded by the insulating sheath 11. However, the protruding conductor 13 can be at least partially or completely free from the cable sheath 8 of the cable 2 over the entire circumference (see Fig.12 ).

[0203] The connection system 1 may have Fig.12 The guide device 70 shown 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 guide the conductor 4, in particular the wire 13 and / or the contact mechanism 28 for contact in the axial direction A of the cable 2. In other words, the guide device 70 can provide linear guidance for the cable 2 and / or the component 20. When the component 20 and the cable 2 are moved relative to each other in a linearly guided manner to make contact, this can also be called a contact movement.

[0204] The guide device 70 may include a guide housing 72 with a guide structure 71. Fig.12In the embodiment, the guide structure 71 is provided in particular in the form of an opening of a guide housing 72 in order to provide mechanical guidance for the respective conductor 4, in particular the cable 13 and / or the contact mechanism 28.

[0206] Furthermore, at least one coding 50 or counter coding 27 having the above-described properties can also be arranged on the guide device 70 , for example in the form of a guide grommet.

[0207] Fig.12 The component 20 and / or a part 44 of the guide 70 can seal the contact surface 9 in the connected state and / or mechanically lock it and / or provide anti-twist protection. Here, for example, an O-ring or a sealing lip on the guide 70 can be considered as a seal. A locking lug (not explicitly shown) or a locking hook can be used as a locking element. A projection or a groove can serve as an anti-twist protection.

[0210] The insertion mechanism 80 may also include a pressure piece 81 and a transmission assembly 82. Here, the transmission assembly 82 can be connected to the pressure piece 81 in a force-transmitting manner so that the pressure piece 81 moves when a force is applied manually or mechanically to the transmission assembly 82. In this way, the respective electrical contact mechanism 28 can be introduced or inserted into the relevant electrical conductor 4 through the pressure piece 81 by means of a contact movement. Here, the stroke 93 of the pressure piece 81 between the starting position 91 and the final position 92 can be determined by a predetermined penetration depth 90 and / or can be predetermined by the structure. In addition, an adjustment mechanism 84 can be provided for adjusting the predetermined penetration depth 90 in the insertion mechanism 80, preferably adjusting the stroke 93, preferably depending on the cable type of the cable 2 and / or continuously and / or in several predetermined stages.

[0211] also, Fig.15 The schematically shown insertion mechanism 80 can be designed as a lever mechanism 80, in which the transmission assembly 82 comprises a lever arm 82. It can be used to transmit a manual or machine force on the transmission assembly 82 into a controllable contact movement, in which the control is carried out in such a way that the contact movement is linearly guided and / or the penetration depth 90 is predetermined and / or controlled and / or limited and / or preset and / or the current penetration depth 90 is marked for the user.

[0212] In addition, you can set Fig.15 An indexing device 83 is shown to indicate the current penetration depth 90 during the contact movement in a visual, tactile or audible manner.

[0213] Fig.16 It is shown that the insertion device 80 can also have 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 is screwed onto the thread 86 for this purpose. In addition, a transmission assembly 82 can be provided, which is designed to transmit the movement, in particular the rotational movement, of the nut 85 on the thread 86 to the pressure piece 81. In addition, the pressure piece 81 can be arranged in the area of ​​a guide space 87 and guided so that it is guided through the guide space 87 of the guide structure 71 by the transmission movement along the longitudinal axis of the strand 86, so as to thereby apply a force for inserting the electrical contact device 28, wherein the guide space 87 is designed to accommodate a part of the component 20 and / or at least one electrical contact device 8.

[0214] In addition, according to Fig.16 A retaining member 88 may be provided which is firmly connected to the pressure member 81 so as to limit contact movement when the retaining member 88 encounters a mating retaining member 89 .

[0215] Fig.11A method 100 for forming an electrical contact between a cable 2 and a component 20 according to an embodiment of the present invention is schematically shown. According to a first step 101, a connection system 1 comprising a cable 2 and a component 20 and a guide device 70 can be provided, wherein the component 20 comprises at least one or more contact means 28 each for contacting the associated conductor 4 of the cable 2. The conductor cross section 5 of the respective conductor 4 can be exposed and accessible from the outside. In addition, according to a second step 102, the respective contact means 28 is passed through the exposed conductor cross section 5 of the associated conductor 4 so as to establish contact between the contact means 28 and the conductor 4. The insertion can be linearly guided by the guide device 70. In addition, the insertion 102 can be controlled by the insertion mechanism 80 so that the respective contact means 28 is inserted into the associated conductor 4 along the axial direction A of the conductor 4 and / or the cable 2 with a predetermined penetration depth 90.

[0216] Fig.17 An embodiment of a connection system 1 according to the invention is schematically shown, which comprises an embodiment of a component 20 according to the invention and an embodiment of a cable 2 according to the invention. The cable 2 has a plurality of mutually spaced strain relief profiles 172. The strain relief profiles 172 are formed as circumferential grooves and are evenly spaced along the cable 2. The strain relief 171 of the component 20 engages in such strain relief profiles 172, wherein the strain relief 171 is formed integrally with the component 20 and prevents accidental pulling of the cable 2 leading to accidental separation of the electrical connection between the cable 2 and the component 20. The electrical connection is established by sharpened contact means, each of which is penetrated into only one predetermined electrical conductor of the cable. The electrical conductors of the cable 2 extend twisted with each other along the length of the cable 2. The cable 2 also has a coding 50, which interacts with a counter-coding of the component 20, so that the contact means of the component 20 only electrically contacts the electrical conductor provided for this purpose during the establishment of the electrical connection between the component 20 and the cable 2, because the coding 50 and the counter-coding together form a guide and prevent any other contact between the conductors of the contact means. To this end, the coding 50 of the cable 2 is formed on the circumference of the cable as a spiral groove or a thread groove extending in the direction in which the cable 2 extends. Alternatively, a flange of similar design can be provided instead of the groove. The coding 50 has a continuous direction in the direction in which the cable 2 extends and has the same relative position relative to the electrical conductor of the cable 2 transversely or perpendicularly to the direction in which the cable 2 extends at each point along the extension of the cable 2. In other words, the cable 2 can be shortened to a desired length at any point in the cable 2 in order to establish an electrical connection between the cable 2 and the component 20, because the constant relative position along the cable ensures the expected electrical contact. The contact surface 9 is formed at the cable end 217, where the contact mechanism is inserted into the cable conductor.

[0217] Fig.18aAn exemplary embodiment of a component 20 according to the invention is shown. A contact mechanism 28 for contacting an electrical conductor of a cable can be seen. The contact mechanism 28 is electrically connected to a contact conductor 180 of a plug 181 of the component 20, which here forms a plug assembly 181. The guide path from the contact mechanism 28 to the contact conductor 180 of the plug 181 is not formed in a straight line, but is preferably inclined at least once in the vertical direction, whereby the plug 181 is formed on one side of the component 20 extending transversely or perpendicularly to the insertion direction of the cable 2. Instead of a plug 181 with a plug assembly 181, a socket with a socket assembly can be provided.

[0218] Fig.18b Another exemplary embodiment of a component 20 according to the invention is shown. Fig.18a The embodiment of the present invention differs in that the plug 181 is formed on the side of the component 20 that faces away from the side of the component 20 where the cable can be electrically contacted with the contact mechanism 28. In addition, the guide path of the contact conductor 180 from the contact mechanism 28 to the plug 181 is formed in such a way that the arrangement and / or distribution of the contact conductor 180 of the plug 181 differs from that of the contact mechanism 28.

[0219] Fig.19a An embodiment of a connection system 1 is shown. Here, the strain relief 171 is formed by a heat shrink tube 191. The heat shrink tube 191 also serves to seal the electrical connection between the cable 2 and the component 20. The heat shrink tube 191 engages in a circumferential groove forming the strain relief profile 172. Furthermore, the heat shrink tube is attached to the component 20.

[0220] Fig.19b A further embodiment of the connection system 1 is shown. Here, the cable 2 has microcapsules 193 which, when in contact with the activating substance 194, release a sealing compound which seals the electrical connection between the cable 2 and the component 20 relative to the environment. Of course, it is also possible that the component 20 has the microcapsules and the cable 2 has the activating substance. Alternatively, it is also conceivable that the activation, i.e. the release of the microcapsules, takes place by heat, light, radiation or another suitable means.

[0221] Fig.19c Another embodiment of the connection system 1 is shown. Here, the sealing cavity 198 in the component, which is bounded by the cable 2 and the component 20, is sealed from the environment by a sealing compound 195. The component 20 preferably has a filling opening 196 for filling the sealing compound 195. In addition, the component 20 can have an outlet hole 197, from which the filled sealing compound 195 can escape if the sealing cavity 198 has been filled with the sealing compound 195. Alternatively or additionally, the component 20 can have an observation window delimiting the sealing cavity 198, whereby the user can visually recognize the extent to which the sealing cavity 198 is filled with the sealing compound 195.

[0222] For ease of representation, the contact mechanism is Fig.17 and Figures 19a to 19c is not shown or is not visible due to the selected diagram.

[0223] The above explanation of the embodiments only describes the present invention by way of example. Of course, without departing from the scope of the present invention, the individual features of the embodiments can be combined freely with one another, as long as this is technically advantageous.
