Definitions

  • the present invention relates to a connection system according to the type defined in the preamble of claim 1. Furthermore, the invention relates to a cable and a method.
  • 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.
  • the object of the present invention is to further simplify the installation technology and to improve the To provide the correct cable layout for an application.
  • the goal is to provide an improved, more flexible, and/or simpler connection technology that can be used in the field.
  • connection system having the features of claim 1 and a cable having the features of claim 27. 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 connection system according to the invention naturally also apply in connection with the cable 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 always made to each other.
  • connection system preferably for a cable and specifically for establishing a connection between the cable and a component.
  • the connection system can comprise the component and the cable and optionally further elements such as a guide device.
  • the cable can be designed as an electrical cable and the component as an electrical component. Alternatively or additionally, the cable and component can also be designed to conduct other media such as liquids or air.
  • the component can be intended for connection to the cable.
  • the component is a connector, an actuator, a sensor, or a module such as a fieldbus module.
  • the component can comprise one or more contact means, each for making contact with an associated conductor of the cable. In other words, if the cable has multiple conductors, these can each be assigned to one of the contact means in order to connect each of the conductors to one of the contact means.
  • the assignment or affiliation can, for example, be determined according to a predefined (electrical) assignment. If the component is designed as an electrical component, the contact means are designed to be electrically conductive. If the cable is designed as an electrical cable, the conductors can correspondingly be designed to be electrically conductive.
  • the cable can be designed such that the respective conductor of the cable is accessible for contacting with the associated contact means.
  • the respective conductor is 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 the case of several Thus, several exposed conductor cross-sections of the cable conductors can be accessible at one contact surface of the cable.
  • connection system can further be designed to contact the respective contact means with the associated conductor in the axial direction of the cable or conductor.
  • the connection system can in particular be designed such that contact is possible by a relative movement of the respective contact means and the associated conductor to one another parallel to the axial direction of the cable or conductor.
  • the respective contact means can be electrically connected directly to the exposed conductor cross-section of the associated conductor, e.g., by being pierced through this conductor cross-section.
  • the respective contact element is electrically connected to a conductor to be contacted (i.e., the associated conductor) by piercing the contact element through the exposed conductor cross-section of the conductor to be contacted. This "piercing" allows for a quick and reliable electrical connection.
  • the respective contact means may have a point and/or be needle-shaped. This allows the conductor(s) to be contacted by piercing the contact means at and/or through the exposed conductor cross-section of the conductor, or by piercing the contact means at and/or through the exposed conductor cross-sections in the axial direction.
  • the conductor(s) are each formed as a stranded wire.
  • the respective stranded wire can comprise flexible individual wires to electrically surround the contact means inserted through the respective conductor cross-section.
  • Each conductor can thus comprise several individual wires, wherein the respective contact means can be surrounded by the individual wires of the conductor into which it has been inserted. This can significantly facilitate the insertion, since the conductor is easier to penetrate due to the flexible individual wires. Furthermore, the electrical connection can be made significantly more reliable.
  • the respective contact means is designed to be inserted, preferably pierced, into the conductor at and/or through the exposed conductor cross-section of the contacting (associated) conductor.
  • each of the contact means can be inserted into a conductor cross-section provided for this purpose.
  • the respective conductor, with its (respective) exposed conductor cross-section and the contact means inserted, preferably pierced, therein can be at least partially surrounded by an insulating sheath.
  • a contacting surface is provided on the cable, at which the conductor(s) are accessible for contacting with the contact means.
  • the contacting surface can lie in a cutting plane of the cable. In other words, the contacting surface can lie at the plane at which the cable was cut.
  • the conductor(s) can border on the outside from an interior of the cable or protrude and be visible from outside the cable.
  • the conductor(s) preferably protrude relative to the contacting surface or are located in a recessed position in the cable. It is also conceivable that the respective exposed conductor cross-section also lies in the cutting plane. This provides an easy-to-connect structure, through which the cable can inherently be designed as a plug or socket.
  • a further advantage within the scope of the invention can be achieved if the respective conductor forms a line with a surrounding insulating sheath, wherein the resulting line(s) can protrude from the contacting surface.
  • the respective protruding line can be only partially surrounded by a cable sheath of the cable or can be at least partially freed from the cable sheath of the cable. It is also possible for the respective protruding conductor and/or the respective exposed conductor cross-section to be completely or partially surrounded by the insulating sheath.
  • the contacting surface can be formed by a cut surface of the cable sheath of the cable. Since only part of the cable sheath is removed, but not every individual insulating sheath of the lines, the effort can be significantly reduced.
  • the connection between the component and the cable can be made directly at a contacting surface, particularly a cross-section of the cable.
  • the contacting surface can refer to a surface, particularly a cross-section through the cable, at which the respective conductor of the cable is or can be accessible from the outside for contacting the contact means of the component.
  • the surface can be arranged orthogonally to the axial direction of the cable.
  • the respective conductor of the cable can be directly adjacent to an outer region of the cable at the contacting surface and thus be connected to the contact means of the component without severing the sheath and/or insulation of the cable.
  • the respective conductor can also be severed at the contacting surface in alignment with the contacting surface.
  • the cable can be designed to provide such a contacting surface after the cable has been cut to size.
  • the cable can be designed in such a way, preferably after the cable has been cut to size, that the respective conductor of the cable is or becomes accessible for contacting with an associated contact means.
  • the respective conductor is or becomes accessible from the outside (i.e. outside the cable), in particular that it can be electrically contacted from the outside without further measures such as stripping.
  • the cable can also have the contacting surface and/or the accessible conductor in its original state (e.g. in the delivered state without cutting).
  • the cut cable can have a plug-in structure, in particular provided by the coding and/or connection structure.
  • the cable can be designed to have a plug-in structure on the cut surface even after cutting. This has the advantage that the cable can be connected directly to the component after it has been cut to a desired length. This is made possible in particular by the plug-in structure being provided continuously or repeatedly in the axial direction along the cable.
  • the cut cable can therefore, as such and thus also immediately after cutting, already have the necessary structure on its cut surface to enable direct connection to the component.
  • the cable is provided with (at least) one contacting surface, at which the respective conductor is accessible for contacting with the associated contact means, and at which the coding is preferably provided.
  • the contacting surface can be located in the cutting plane of the cable. In other words, the contacting surface can be located at the plane at which the cable was cut.
  • the cable can be designed so that after cutting it has a contact surface, preferably with the coding, on the cut surface.
  • the conductor(s) may be adjacent to the contact surface or cut plane, or they may protrude from the interior of the cable and be visible from the outside.
  • the respective conductor is preferably protruded from the contact surface or located in a recessed position within the cable. It is also conceivable for a respective exposed conductor cross-section to also be located in the cut plane. This provides an easy-to-connect structure, allowing the cable to be inherently configured as a plug or socket.
  • a further advantage can be achieved within the scope of the invention if a geometric profile, in particular a spatial shape and/or contour, extends in the axial direction of the cable.
  • the profile can define a guide cavity for a guide means and preferably for a guide pin of the component in order to mechanically guide the contact in the axial direction of the cable. This can serve to guide the introduction of the contact means(s) into the conductor(s) in the axial direction of the cable or conductors and thus further simplify the production of the contact and avoid errors in the contact.
  • the guide cavity can particularly preferably be designed to transmit a fluid, in particular to transmit a medium such as air or a liquid.
  • the connection system has a guide device.
  • the guide device can be designed separately from the cable and the component.
  • the guide device can optionally be movably connected to the cable and/or the component, e.g., via a band or a loop.
  • the guide device can also be designed as a (e.g., integral) part of the cable or the component.
  • the guide device can be designed to mechanically guide the contact in the axial direction of the cable or the respective conductor, and preferably to guide the conductors, in particular the lines, and/or the contact means for contacting in the axial direction of the cable.
  • the guide device is thus a tool for simplifying contacting without, for example, stripping and/or crimping.
  • the guide device has a guide housing with a guide structure, preferably in the form of openings in the guide housing, in order to provide the mechanical guidance for the respective conductors, in particular lines, and/or contact means.
  • the guide structure for receiving the conductors, in particular lines can be formed on one (first) side of the guide housing. On another side, preferably opposite in the axial direction of the guide device (the first side) and/or
  • the guide structure can be designed to accommodate the contact means on the (second) side of the guide housing facing away from the guide device. This can serve to provide contact in an interior of the guide housing of the guide device and/or to mechanically guide the insertion of the contact means into the conductors in the axial direction of the cable or conductors for contacting purposes. This makes the connection easier and more secure. If the contact is provided in the interior of the guide device, mechanical protection and/or sealing can also be provided.
  • the (multiple) conductors may each form a line with a surrounding insulating sheath, wherein the lines are color-coded, in particular by a different color of the insulating sheath.
  • a corresponding counter-coding can be provided on the guide device to color-code a guide structure and preferably openings of the guide housing to the corresponding lines, e.g., by applying the same colors to indicate openings associated with the lines. This allows the conductors to be assigned to the component more securely and reliably.
  • a further advantage can be achieved within the scope of the invention if at least one coding is spatially formed on the cable and/or on the guide device in order to prescribe a specific arrangement and assignment of the contact means of the component with the electrical conductors of the cable.
  • the conductors have specific functions and therefore a correct assignment to the contact means must be made.
  • the assignment can be provided, for example, by color coding, or alternatively or additionally by mechanical coding.
  • the coding is formed, for example, on the cable itself, e.g. by a specially shaped cavity. It is also conceivable for the guide device to have the coding.

  • the at least one coding can be formed by means of a rotationally symmetrical cross-section of the cable, in particular by means of a rotationally symmetrical inner and/or outer contour of the cable. This ensures that the cable can only be electrically connected to the component in a position that corresponds to a clear assignment of the contact means to the electrical conductors of the cable.
  • the rotationally symmetrical outer contour can be formed by means of a cable sheath or outer circumference of the cable, preferably in that the cable has a cross-section with a circular basic shape and at least one recess, in particular a groove, and/or at least one elevation, in particular a bead.
