Description

[0001] The present invention relates to a connection point, a connection module with at least one such connection point and a system with such a connection point or such a connection module. State of the art

[0002] Electrical push-pull connectors are a well-established technology and are frequently used in connection technology for the secure and reliable connection of electrical cables or devices. The term "push-pull" describes the operating principle of these connectors, which can be connected and disconnected by simply pushing them in (push) and pulling them out (pull) from their designated connection points. This allows for quick and easy handling without the need for special tools.

[0003] To ensure high mechanical stability and ease of use, various locking mechanisms are available. The bayonet lock, where the connector is locked by a twisting motion, allows for easy handling and quick connection. The spring-loaded lock, based on spring elements, also enables a simple and secure connection. Sliding locks utilize a sliding mechanism that automatically locks the connector elements upon insertion and unlocks them again when needed. A rotary lock is also known, in which the connector is locked to the mating surface by a twisting motion that locks the connector axially. The choice of locking mechanism depends on the application, environmental conditions, and other factors.

[0004] A disadvantage of state-of-the-art connectors is their complex design. Furthermore, finding a solution for attaching the connector to the designated connection point is complex and time-consuming. Disclosure of the invention

[0005] It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to achieve improved detachability of the fastening of a cable, especially a cable connector, with a connection point.

[0006] The foregoing problem is solved by a connection point, a connection module and a system with the features of the corresponding independent claims.

[0007] Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings. Features and details described in connection with the connection point according to the invention naturally also apply in connection with the connection module and the system according to the invention, and vice versa, so that the disclosure regarding the individual aspects of the invention always refers to, or can refer to, each other.

[0008] The problem is solved in particular by a connection point for a connection module for establishing a connection with a cable by means of a first connection structure of the connection point and a second connection structure of the cable, preferably a connector of the cable, wherein the connection point comprises a contact element which is designed for connection with the cable, wherein in a fastening position of the first connection structure a mechanical, in particular force-fit and / or form-fit, fastening of the cable, in particular of the second connection structure, preferably of the connector of the cable, to the connection point can be formed by connecting or bringing into contact with the second connection structure in order to secure a connection of the contact element with the cable and / or to prevent an unintentional loosening of a connection of the contact element with the cable.wherein the fastening is releasable by the first connecting structure being releasable from the second connecting structure, wherein the first connecting structure can be moved from the fastening position to a release position by means of a movement of the first connecting structure in order to release the fastening.

[0009] This overcomes at least some or all of the aforementioned disadvantages of the prior art. In particular, the invention achieves improved detachability of a cable, especially a cable connector, from the connection point. Furthermore, an advantage lies in the fact that the simplified detachability is achieved solely through the inventive design of the connection point, without requiring any special modification of the cable or connector.

[0010] The connection between the terminal and the cable, which can be established, can involve fastening the cable, particularly the connector. In other words, it can involve fastening the cable, especially the connector, to the terminal.

[0011] The connection between the contact element and the cable can be a data-transmitting and / or hydraulic and / or pneumatic and / or electrical connection between the cable and / or the connector and the contact element. For this purpose, the contact element can include a data-transmitting and / or hydraulic and / or pneumatic and / or electrical connection. Through this connection, data and / or fluids and / or gases and / or electrical energy can be transmitted to and / or received from a suitable cable that can be connected to the connection point, provided that this cable is preferably connected to the contact element.

[0012] The connection point may be designed in such a way that both the cable and the contact element, as well as the cable, and in particular the connector, can be connected or fastened to the connection point. Furthermore, it is conceivable that the connection point is designed in such a way that connecting the cable to the contact element necessitates connecting or fastening the cable, and in particular the connector, to the connection point, and / or vice versa.

[0013] Furthermore, it can be provided that the cable, in particular the connector, can be attached to the connection point, in particular by means of the first connection structure, while the cable, in particular the connector, can only be connected directly to the contact element without any fastening. In other words, preferably no direct fastening of the cable, in particular the connector, to or on the contact element is possible, while fastening of the cable, in particular the connector, can take place directly at the connection point, in particular on the first connection structure.

[0014] The contact element can also include a contour designed to interact with a corresponding counter contour of a cable, in particular a connector of the cable for which the contact element is designed, such that the cable and / or connector can be connected to the contact element in a predetermined orientation. The predetermined orientation of the cable for connection can ensure that the intended electrical and / or data lines and / or hydraulic and / or pneumatic fluid channels of the connector and the cable can be connected to each other conductively and / or transmittively as intended. Furthermore, it is conceivable that the contact element may have a cylindrical shape. The contact element can also be made of plastic or a plastomer.Electrical, hydraulic, data-transmitting, or pneumatic lines can be located within the contact element in order to be connected to corresponding lines of the cable or connector. Such lines can extend to other contact elements or other connection points according to the invention.

[0015] Furthermore, it may be provided that the first connection structure can be moved not only from the fastening position to a release position to loosen the fastening, but also to loosen the connection of the contact element from the cable, in particular from the connector. In other words, the first connection structure can be moved from the fastening position to a release position to loosen the fastening, in particular of the cable or connector, from the connection point, in particular the first connection structure, as well as to loosen the connection of the contact element from the cable or connector.

[0016] In a preferred embodiment, the connection point may include a recess with a cable insertion opening, in particular a connector insertion opening, into which the cable, in particular the connector, can be inserted to form the fastening, and the first connection structure is located in the recess.

[0017] Advantageously, the recess at the cable entry opening or the connector entry opening can be designed to have an insertion chamfer for the cable or connector. This improves ease of assembly.

[0018] Furthermore, it is conceivable that the connection point is designed in such a way that by inserting, in particular by pushing, the connector or cable into the recess, the first connection structure can be moved into the release position. This simplifies assembly.

[0019] It may also be provided that the cable entry opening, in particular the connector entry opening, is surrounded by a collar. The collar may be formed, at least partially, by a sealant, in particular one described elsewhere.

[0020] It is also possible that the contact element, particularly in the release or fastening position of the first connection structure, is partially or completely located within the recess. This protects it, at least partially, from environmental influences.

[0021] Furthermore, the recess can have an essentially cylindrical basic shape.

[0022] Furthermore, it may be provided that the first connecting structure partially limits the recess, particularly in the radial direction, or surrounds the contact element.

[0023] It is also conceivable that a cylindrical surface, in particular, limits the recess in the radial direction. The first connecting structure can be formed on this cylindrical surface.

[0024] Furthermore, the cable entry opening, particularly the connector entry opening, can be designed such that its diameter increases when the first connection structure is moved from the fastening position to the release position. In other words, the cable entry opening, particularly the connector entry opening, has a larger diameter in the release position of the first connection structure than in the fastening position. This simplifies the insertion and removal of a cable or connector from or into the recess of the connection point.

[0025] Furthermore, it can be provided that the first connection structure is designed such that its diameter or its distance to the contact element increases when the first connection structure is moved from the fastening position to the release position. In other words, in the release position, the first connection structure has a larger diameter or a greater distance to the contact element than in the fastening position. This allows a cable or connector to be inserted and / or removed from the recess of the connection point. The diameter in the release position can be so large that the first connection structure is arranged without contact to the second connection structure, thus ensuring a particularly reliable release of the fastening. The diameter can refer to a circle or cross-section enclosed by the connection structure.

[0026] In a further preferred embodiment, the connection point and / or the first connection structure can be designed such that, when the first connection structure is moved from the fastening position to the release position, a base of the recess moves in the direction of the cable entry opening, in particular the connector entry opening, and / or the diameter of the cable entry opening, in particular the connector entry opening, increases, and / or the contact element moves against an insertion direction of the connection point, and / or the first connection structure moves away from the contact element, and / or a restoring force is formed or can be formed due to the elasticity of the connection point and / or the first connection structure, which is able to move the first connection structure back into the fastening position.All these features can relate to the transition of the first connection structure from the fastening position to the release position. The recess can include a base. The first connection structure can be returned to the fastening position, or is returned to it, by means of the restoring force when a force that moves the first connection structure to the release position diminishes, ceases, or falls below the value of the restoring force.

[0027] Instead of or in addition to the connection point and / or the first connection structure being designed in this way, segments and / or a sealant and / or deformation points can be designed and / or arranged in this way. In other words, the elasticity of the sealant and / or the segments and / or the deformation points, by means of which the restoring force can be generated, can be meant alternatively or additionally. The segments, the sealant, and the deformation points will be discussed in more detail elsewhere.

[0028] By moving the contact element in the opposite direction to the insertion direction of the connection point, the connection of the cable or connector can be more easily disconnected from the contact element. The insertion direction of the connection point can refer to the direction in which the contact element extends and / or in which a cable or connector must be moved when inserting the cable or connector into the recess, particularly to create a connection or fastening.

[0029] Furthermore, it may be provided that the connection point and / or the first connecting structure is designed in such a way that a cylindrical wall of the recess, bounding the recess, bulges when the first connecting structure is moved from the fastening position to the release position.

[0030] Instead of or in addition to the connection point and / or the first connection structure being designed in this way, segments and / or a sealant and / or deformation points can be designed and / or arranged in this way. The segments, the sealant, and the deformation points will be discussed later.

[0031] It can also be provided that the contact element is formed as a single unit with the base.

[0032] In a further preferred embodiment, the fastening can be formed by means of a screw connection, the first connection structure being designed as a thread, in particular an internal thread, preferably an M12 internal thread, to form the screw connection together with the second connection structure, in particular a mating thread of the cable, preferably an external thread of the connector, and the cable, in particular the connector, being able to be led out of the recess without any screw movement when the first connection structure is moved from the fastening position to the release position. In other words, the fastening can be released without any screw movement in this way. Furthermore, the fastening can be released extremely quickly and easily in this way, since time-consuming screwing operations can be avoided.It is also conceivable that the connection between the contact element and the cable or connector can be detachable without screwing. In other words, the connection point can form an M12 port or M12 connection if it uses an M12 internal thread. The external thread of the connector can be an M12 external thread. Other dimensions for the internal and / or external thread are also conceivable, for example, M4, M5, M6, M7, M8, M9, M10, M11, M14, M16, M18, M20, M22. Sizes between M5 and M16 are also possible. The internal and / or external thread can be left-hand or right-hand. Furthermore, the internal and / or external thread can be metric or imperial. Furthermore, it can be a standard thread, a trapezoidal thread, or a fine thread.Preferably, internal threads and external threads, in particular according to their type and / or their dimensions, can be matched to each other in such a way that the screw connection can be formed by means of them.

[0033] In a further preferred embodiment, it can be provided that the fastening can be formed by means of a clamping connection, that the first connection structure comprises clamping elements in order to form the clamping connection with the second connection structure.

[0034] Advantageously, the first connection structure, in particular the clamping elements, can be pre-tensioned, preferably in the mounting position, to clamp the cable, in particular the connector, and thus form the clamping connection. Preferably, the first connection structure, in particular the clamping elements, can be pre-tensioned in the direction of where the second connection structure would be located if the cable or connector were attached to the connection point, in order to clamp the cable, in particular the connector, and thus form the clamping connection.

[0035] It is also possible that the second connection structure is designed as a clamping contour.

[0036] In a further preferred embodiment, it can be provided that the fastening can be formed by means of a positive locking connection, and that the first connection structure comprises positive locking elements to form the positive locking connection with the second connection structure.

[0037] Advantageously, the positive locking elements can be designed as gripping elements or hook elements to form the positive locking connection with the second connection structure. The second connection structure can comprise a counter-positive locking contour, in particular a gripping contour, an engaging contour, openings, recesses or a shoulder, or counter-positive locking elements for the positive locking elements, in particular gripping elements or hook elements.

[0038] In a further preferred embodiment, it can be provided that the first connection structure is biased in a direction in which the contact element and / or the second connection structure would be located if the cable, in particular the connector, were attached to the connection point and / or were located in the recess, and / or that the first connection structure is in an unloaded position or in a standard or initial position in the mounting position.

[0039] In a further preferred embodiment, the first connection structure may be divided into individual, separately movable segments and / or the connection point or the first connection structure may comprise a hard component, in particular a plastomer. The hard component may therefore be a plastomer. Instead of comprising the hard component or the plastomer, the first connection structure may consist of a hard component or a plastomer. The hard component may be harder or harder, and in particular less flexible and / or less elastic, compared to a soft component or another component. Alternatively, a plastic may also be used.

[0040] The segments can be movable independently of each other in such a way that relative movement of the segments to each other or of adjacent segments to each other is possible.

[0041] The segments may be connected to each other by means of a base or the base of the recess, thereby transmitting force. Preferably, the segments may be formed as a single unit, or the segments and the base may be formed as a single unit. Alternatively, the segments and the base may be formed as a single unit together with a cover or another housing component.

[0042] Furthermore, the segments can be uniformly and / or uniformly distributed and / or arranged.

[0043] It is possible that the segments, or the segments with the base, are or will be formed by means of plastic injection molding, especially in one piece.

[0044] Furthermore, it may be provided that the connection point and / or the first connecting structure are designed in such a way that they only experience elastic deformation during the transition of the first connecting structure from the fixed position to the release position. In other words, plastic deformation during this process may be excluded.

[0045] In a further preferred embodiment, adjacent segments may be spaced apart from one another, thereby forming gaps between the segments. These gaps are sealed, in particular by means of an elastic sealant, especially a soft component, preferably an elastomer. The elastic sealant is preferably designed as an optical fiber, which in particular comprises a translucent material. The sealant may comprise or consist of a soft component or an elastomer. The soft component may be softer, or softer, in particular more flexible and / or elastic, compared to a hard component or another component. Instead of comprising a translucent material, it is conceivable that the optical fiber consists of a translucent material.

[0046] Advantageously, the elastic sealant can be designed to be so elastic that it allows relative movement between adjacent segments.

[0047] It is possible that the seal is designed to be fluid-tight, in particular liquid- and / or gas-tight, preferably water- and / or air-tight.

[0048] By being designed as a light guide, the elastic sealant can be used to transmit data or signals. This integrates an additional function.

[0049] The sealant is preferably an elastomer. This reduces costs.

[0050] Furthermore, the separation gaps can be uniform and / or evenly distributed, particularly around the recess and / or cable entry opening, preferably the connector entry opening. Furthermore, the separation gaps can have uniform dimensions along their entire length.

[0051] Furthermore, the separating gaps can extend from the cable entry opening, preferably the connector entry opening, to the bottom or a bottom of the recess. Alternatively or additionally, the separating gaps can extend radially away from the cable entry opening, preferably the connector entry opening. In principle, the radial direction can extend transversely or perpendicularly to the insertion direction of the cable, particularly the connector, into the connection point, especially into the recess. Alternatively, the radial direction can run transversely or perpendicularly to the direction of extension of the contact element.

[0052] It can be provided that, by means of the sealant used to seal the separation gaps, a protrusion is formed at at least one separation gap, particularly at a radially outer end or end region of the separation gap. This protrusion preferably extends in the opposite direction to the insertion direction of the cable, particularly the connector, into the connection point, especially into the recess. Such a protrusion can be designed as a screw locking device for a connector, in particular by securing a connector that can be fastened to the connection point by means of a screw connection. The protrusion presses against the connector when the connector is fastened to the connection point by means of the screw connection, thus achieving a secure fastening.

[0053] Furthermore, it can be provided that at at least one point where the raised area formed by the sealant is located, the sealant extends, in particular in a rod-like form, preferably comprising a square or rectangular cross-section, in the insertion direction. If the connection point belongs to a housing, the sealant can extend into the interior of the housing at said point.

[0054] It is also possible that the collar is formed using the sealant and / or the segments.

[0055] In a further preferred embodiment, a sealing lip may be formed on the base to seal the contact element against the environment when a cable, in particular a connector, is attached to the connection point. The sealing lip is preferably formed by means of a sealant, in particular a soft component, preferably an elastomer. The sealant may comprise or consist of a soft component or an elastomer. The soft component may be softer, or more flexible and / or elastic, compared to a hard component or another component. The environment may be the surrounding environment, in particular the connection point, or environmental influences.Furthermore, the seal can be liquid-tight, in particular waterproof, and / or gas-tight, in particular airtight. The connection point and / or the sealing lip and / or the first connection structure can be designed such that the cable or connector, when attached to the connection point and / or the first connection structure, is able to exert a contact force against the sealing lip, in particular to increase the sealing effect. It can additionally or alternatively be provided that the connection point and / or the first connection structure and / or the segments and / or the sealing lip and / or the base are designed such that the contact force is reduced by moving the first connection structure from the fastening position to the release position and / or increased by moving the first connection structure from the release position to the fastening position.

[0056] Advantageously, it can be provided that during the production of the connection point, the recess with the first connecting structure and the base is produced first, before the separating gap between the segments and the sealing lip are formed using the sealant.

[0057] Preferably, a two-component or multi-component injection molding process can be used for this purpose. This simplifies manufacturing. The first component of the two-component or multi-component injection molding process is a hard component, in particular a plastomer, while the second component is the sealant, preferably the soft component, in particular an elastomer. This allows the connection point or a housing part comprising the connection point to be produced using a simple process.

[0058] It can be generally provided that the transition or movement of the first connection structure from the fixed position to the release position is enabled by elastic deformability of the connection point and / or the first connection structure and / or the segments and / or the sealant and / or deformation points. The deformation points can be areas, in particular areas of the connection point and / or the first connection structure and / or the segments, that are designed to be more elastic and / or deformable compared to adjacent areas. This can be achieved through targeted material weakening, for example, by a thin-walled design, and / or by selecting an appropriate material.Preferably, such deformation points can be arranged and / or designed such that the contact element is guided or moved out of the recess and / or the cable entry opening, in particular the connector entry opening, when the first connection structure is moved from the fastening position to the release position. The deformation points can also be arranged and / or designed such that the contact element is guided or moved into the recess and / or the cable entry opening, in particular the connector entry opening, when the first connection structure is moved from the release position to the fastening position. Furthermore, the deformation points can be arranged at a transition from the base of the connection point to a cylindrical wall of the recess of the connection point, on which, in particular, the first connection structure is located.Further deformation points can be arranged radially away from the cable entry opening or the connector entry opening of the recess, with at least two deformation points per segment being radially spaced apart from each other. The deformation points can be formed on any of the segments of the connection point or of a cover on which the connection point is formed. A restoring force can be generated by the elasticity.

[0059] It may be provided that the contact element is formed as a single unit with the base.

[0060] In principle, it can be designed so that the elastic deformation, or in particular the elastic deformation alone, resulting from the transition of the first connecting structure from the fixed position to the release position, generates a restoring force for returning or moving the first connecting structure back into the fixed position. This makes separate restoring mechanisms partially or completely obsolete and thus saves costs.

[0061] In a further preferred embodiment, it can be provided that the first connection structure is coupled to a release mechanism in a force-transmitting manner, by which the first connection structure can be moved into the release state, and that a force to be transmitted to the first connection structure can preferably be deflected by the release mechanism.

[0062] Advantageously, it can be provided that the segments are connected to each other by means of the base of the recess in a force-transmitting manner, that the segments are preferably formed in one piece with the base, and that the base has a force introduction point for the release mechanism on a side facing away from the cable entry opening or the connector entry opening in order to transmit a force to be transmitted by means of the release mechanism to the first connection structure.

[0063] The release mechanism may include a force diversion to redirect the force transmitted by the release mechanism. This force diversion can be achieved using a gearbox, particularly a linkage gearbox. Alternatively, the release mechanism may incorporate a force diversion designed as a rocker arm.

[0064] It can also be provided that the force redirection is achieved by means of a first force transmission element and a second force transmission element, wherein the two force transmission elements have linear directions of movement and are arranged at an angle to each other by which the force can be redirected. By means of the first force transmission element, a force vector can be generated upon force-transmitting contact between the first force transmission element and the second force transmission element. This force vector has a directional component in the direction of movement of the second force transmission element and acts upon the second force transmission element. The two directions of movement can correspond to the extension directions of the respective force transmission elements. One or both force transmission elements can be designed as push rods and / or tension rods.A first force transmission element can be designed as a push rod, while the second force transmission element is designed as a pull rod, or vice versa. A contact contour designed for force transmission on one of the force transmission elements, particularly the second force transmission element, can be designed as a ramp or plunger, while the contact contour of the other force transmission element can be designed as a hump.

[0065] Furthermore, the second force transmission element can be associated with or facing the first connecting structure or the ground, while the first force transmission element can be associated with the force introduction into the release mechanism.

[0066] It may be provided that the release mechanism is designed such that by applying a force by pulling or pushing, in particular on the first force transmission element, a pressure force can be generated by means of the second force transmission element on the bottom of the recess from the side of the bottom facing away from one of the cable insertion openings, in particular connector insertion openings, in order to transfer or move the first connection structure from the fastening position to the release position.

[0067] Furthermore, the release mechanism can be designed as an electrical, electromechanical, or electromagnetic actuator. For this purpose, the connection point can have an activation element, such as a push button or a lever. This increases ease of use. Alternatively, the release mechanism can be operated manually, particularly by hand. In other words, the force can be applied manually. This is a particularly simple and cost-effective design.

[0068] In a further preferred embodiment, the release mechanism may include an actuating element by means of which a force, in particular manually and / or by hand, can be introduced into the release mechanism and the introduced force can be transmitted by means of the release mechanism to the first connecting structure in order to move the first connecting structure into the release position, and preferably by a pulling or pushing movement of the actuating element, the first connecting structure can be moved into the release position by means of the release mechanism. Accidental release is less likely with a pulling movement than with a pushing movement.

[0069] Preferably, the actuating element can be formed in one piece with the first force transmission element.

[0070] It may be provided that the release mechanism is designed in such a way that a force can be applied by pulling or pushing on the actuating element, and a pressure force can be generated by means of the second force transmission element on the bottom of the recess from one side of the bottom facing away from the cable entry opening, in particular the connector entry opening, in order to move the first connection structure from the fastening position to the release position.

[0071] Advantageously, the actuating element can be designed as an electrical, electromechanical, or electromagnetic actuator. For this purpose, the connection point can include an activation device, such as a push button or a toggle switch. This increases ease of use.

[0072] It may also be provided that the connection point is designed in such a way that a cable or connector can be inserted into the recess of the connection point in the release position in order to then effect a fastening of the cable or connector to the connection point by transferring or being transferable the first connection structure from the release position to the fastening position.

[0073] In a further preferred embodiment, the release mechanism may include a preload mechanism by means of which the release mechanism generates a force that moves the first connecting structure into the fastening position and / or the release mechanism into a position corresponding to the fastening position when the first connecting structure is in a position other than the fastening position and / or the release mechanism is in a position other than the fastening position. In principle, the phrase "corresponding to the release position" or "fastening position" can mean that the position is associated with the release position or the fastening position. In other words, it can refer to positions of the actuating element in which the release position or the fastening position can be effected by means of the actuating element.

[0074] Advantageously, the preload mechanism can be designed by means of a return spring or by elasticity of the connection point and / or the first connection structure and / or the segments and / or the deformation target points.

[0075] In a further preferred embodiment, the actuating element can be locked in a position corresponding to the release position, particularly to simplify the design of the fastening, and / or locked in a position corresponding to the fastening position, particularly to prevent unintentional or accidental loosening of the fastening. The locking mechanism(s) can be releasable, and the locking mechanism(s) can be designed to be, in particular, mechanical, electronic, or magnetic. The mechanical locking mechanism can be formed by means of a positive locking connection, in particular a positive locking connection. The positive locking connection, in particular the positive locking connection, can be formed by means of the actuating element and preferably a housing part, in particular a cover of a connection module, or a connection module that has such a connection point.The magnetic locking mechanism can be designed using a magnet that holds or secures the actuator in position. The simplified design of the fastening, achieved by locking the actuator in a position corresponding to the release position, allows a cable or connector to be easily inserted into the recess without having to manually operate the actuator during this process.

[0076] In a further preferred embodiment, the actuating element, in the position corresponding to the fastening position, may generate a force by means of one or more preloading mechanisms, which, upon release of the locking mechanism, moves the first connecting structure into the release position by means of the release mechanism. Alternatively, the actuating element, in the position corresponding to the release position, may generate a force by means of a preloading mechanism, which, upon release of the locking mechanism, moves the first connecting structure into the fastening position by means of the release mechanism. This increases the speed at which the fastening can be released or assembled.

[0077] Advantageously, it can be provided that such a locking mechanism is designed by means of a releasable positive locking connection.

[0078] In a further preferred embodiment, a connection point according to claims 1 and / or 2 and / or 3 as well as 6 and / or 7 and / or 8 and / or 9 and / or 10 and / or 11 and / or 12 and / or 13 and / or 14 can be provided.

[0079] Regardless of whether aspects of the connection point are depicted or disclosed with a cable, in particular a connector, it may be intended to protect only the connection point and subsequently only the connection module, without the cable or connector. Therefore, the connection point and the connection module are hereby disclosed without a cable, in particular without a connector, in every disclosure with a cable, in particular without a connector. In such a case, the individual features or aspects of the connection point or the connection module that are disclosed in conjunction with the cable, in particular the connector, may be understood as being designed for this purpose, i.e., to interact with the cable, in particular the connector, and in particular without including the cable or the connector.

[0080] Regardless of whether the aspects of the connection point are depicted or disclosed without a cable, in particular without a connector, it may be intended to protect the connection point and subsequently the connection module with the cable or connector, therefore the connection point and the connection module are hereby also disclosed with a cable, in particular with a connector, in every disclosure without a cable, in particular without a connector.

[0081] The invention also relates to a connection module comprising at least one connection point according to the invention, wherein the connection module in particular has a housing comprising a hard component, preferably a plastomer. The connection module according to the invention thus offers the same advantages as those described in detail with reference to a connection point according to the invention. Instead of comprising a hard component, preferably a plastomer, the housing or a housing part may consist of a plastomer. Such a connection module preferably comprises two, three, four, five, six, seven, eight or more such connection points.

[0082] The connection module may be designed to have a housing with at least two housing parts. The first housing part may be a base housing, and the second housing part may be a cover for the base housing. The two housing parts may be ultrasonically welded together, particularly to create a watertight or airtight seal, or simply screwed together. A screw connection may necessitate a separate seal if a specific level of sealing is required. The first and / or second housing part comprises or consists of a hard component, preferably a plastomer. Alternatively, a plastic may be used for the first and / or second housing part.

[0083] It may be provided that the second housing part, in particular the cover, is formed in one piece with the connection point or the first connection structure.

[0084] Furthermore, a support plate may be provided within the housing. This support plate can serve to support a return spring against both the support plate and the second force transmission element, ensuring that the release mechanism returns to its initial position when the force required to move the first connection structure from the fastening position to the release position ceases. The initial position may correspond to a position in which the first connection structure is in the fastening position. It may be provided that the return spring allows the first connection structure to be moved from the release position to the fastening position when the force required to move the first connection structure from the fastening position to the release position ceases.This can occur particularly when the second force transmission element is coupled to the bottom of the recess in two opposite directions. In principle, the return spring can be arranged and / or clamped between the second force transmission element and the support plate, especially in such a way that the spring force acts against both the support plate and the second force transmission element.

[0085] The release mechanism can have a movement limitation in one direction or in two opposite directions to ensure that the connection point and / or the segments and / or the deformation points experience a maximum permissible deformation, in particular elastic, preferably non-plastic, when the first connection structure is moved from the release position to the fastening position and / or from the fastening position to the release position. In other words, the release mechanism can be limited to a movement that is only between positions corresponding to the release position and the fastening position.

[0086] It can also be provided that a circuit board is arranged in the housing, which is in electrical or data-transmitting contact with a cable or a connector that can be attached to the terminal, if the cable, connector, or cable connector is conductively connected to the contact element. In other words, the contact element can be conductively connected to the circuit board. If the terminal module has several connection points according to the invention, several or all of the contact elements can be conductively connected to the circuit board. The circuit board can also be designed as a support plate. Furthermore, the circuit board can be designed as a guide and / or movement limiter for one of the force transmission elements, in particular for the force transmission element facing the ground, especially such that only linear movement is possible.It is preferred if the actuating element penetrates the circuit board or the support plate.

[0087] The invention also relates to a system comprising a connection point or a connection module according to the invention, wherein the system includes a cable, the cable being connected to the contact element, in particular electrically and / or hydraulically and / or pneumatically and / or for data transmission, wherein the cable, in particular a connector of the cable, comprises a second connection structure, wherein the cable, in particular the connector of the cable, is attached to the connection point by means of a fastening, in that the first connection structure is connected to the second connection structure. Thus, the system according to the invention offers the same advantages as those described in detail with reference to a connection point or a connection module according to the invention.The system can be a fieldbus or a bus system that connects sensors and actuators to a control computer (PLC) for information exchange.

[0088] The system may also include data terminal equipment, in particular a data source and a data sink, which are interconnected for data transmission via the connection module. Additionally or alternatively, the system may include a power source and an electrical component, wherein the power source, for example an external power grid or a battery, and the electrical component, for example a machine tool, are electrically connected via the connection module.

[0089] The invention also relates to a cable for the connection point, a connector for the connection point, or a cable for the connection point that includes a connector for the connection point. In other words, the cable, the connector, and the cable that includes a connector are compatible with and / or connectable to the connection point. This provides a cable and / or a connector that is compatible with the connection point according to the invention.

[0090] The invention also relates to a method for releasing a fastening of a cable, in particular a connector of a cable, at the connection point according to the invention, comprising: Introducing a force into the release mechanism by means of the actuating element, in particular by pulling or pushing the actuating element; transmitting the introduced force by means of the release mechanism to the bottom of the recess, from a direction away from the cable entry opening or connector entry opening, in order to move the first connection structure from the fastening position to the release position; moving the first connection structure from the fastening position to the release position in order to release the fastening, in particular by moving the first connection structure designed as an internal thread away from the second connection structure designed as an external thread, due to the force introduced onto the bottom; pulling the cable out of the connection point while the force acts on the first connection structure to release the contact of the cable from the contact element.

[0091] The method thus offers the same advantages as those described in detail with reference to a connection point, connection module, and system according to the invention. The method can be used with the connection point, connection module, or system according to the invention.

[0092] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. The drawings show: Fig. 1 A schematic embodiment of the system according to the invention, Fig. 2 a view of an embodiment of the connection module according to the invention, Fig. 3athe section view AA of the section path AA from Figure 2 , Fig. 3b The section view BB of the section path BB is shown from a perspective perspective. Figure 2 , Fig. 3c schematically the section view CC of the section path CC from Figure 2 , and Fig. 3d schematically another section view CC of the section path CC from Figure 2 .

[0093] In Figure 1Figure 1 schematically illustrates an embodiment of the system 1 according to the invention. The system 1 comprises a connection module 3, which has four connection points 4. Furthermore, the system 1 comprises two data terminal devices 2a, 2c, one of which is configured as a data source 2a and the other as a data sink 2c. The two data terminal devices 2a, 2c are connected to each other for data transmission via the connection module 3. The two data terminal devices 2a, 2c are each connected to the connection module 3 for data transmission via cables 6. The system 1 also comprises a power source 2b and an electrical component 2d. The power source 2b, for example, an external power grid or a battery, and the electrical component 2d, for example, a machine tool, are electrically connected to the connection module 3. The power source 2b supplies the electrical component 2d with electrical energy via the connection module 3.The cables 6 each have a connector 7. Each of the connectors 7 is connected to a terminal 4 of the connection module 3 and thus secured.

[0094] In Figure 2Figure 1 shows a view of an embodiment of the connection module 3 according to the invention. For the sake of simplicity, the connection module 3 shown here comprises only two connection points 4, although eight or more connection points 4 would be conceivable. A cable or a cable connector can be attached to the connection point 4 and thus to the connection module 3 by means of such a connection point 4. Each of the connection points 4 comprises a first connection structure, wherein these connection structures are each subdivided into eight independently movable segments 4a. Adjacent segments 4a form slots which are sealed liquid-tight by means of an elastic sealant 4b. This protects the interior of the connection module 3 from the ingress of moisture.The sealant 4b is designed to be elastic, allowing movement of adjacent segments 4a in different directions. The sealant 4b is a soft component, specifically an elastomer, designed as a light guide by incorporating a translucent material. The segments 4a are connected to each other by means of a recess in the connection point 4, thus transmitting force. Furthermore, the connection module 3 has an actuating element 5a for each connection point 4. This actuating element 5a allows the respective first connection structure to be moved, i.e., switched, from a fixed position to a released position. This enables quick and easy release of a connector to the connection point.Furthermore, a horizontal section AA, a vertical section BB and a diagonal section CC, each passing through the right connection point 4, are shown.

[0095] In Figure 3a is the section view AA of the section path AA from Figure 2This view shows three housing parts 3a, 3b, and 3c of the connection module 3, which are made of plastic or a plastomer and each manufactured using an injection molding process. The first housing part 3a is a cover, while the second housing part 3b is a base plate. The third housing part 3c is a support plate. The support plate can be designed as a circuit board connected to a contact element 4g by means of electrical conductors. This simultaneously connects a cable, which is attached to the connection point 4 and electrically connected to the contact element 4g, to the circuit board. The cover is ultrasonically welded to the base plate after the support plate has been clamped between the base plate and the cover or ultrasonically welded to the base plate.The connection point 4 is integrated into the cover, so that both the cover and the connection point are made of the same material, a plastic or a plastomer. The cover with its connection point 4 can be manufactured using two-component injection molding. One of the components can be a hard component, in particular a plastomer, while the other component can be the sealant 4b, i.e., the soft component, in particular an elastomer. Two-component injection molding is a suitable manufacturing process, with the first component being the plastomer and the second component being the sealant 4b. The connection point 4 comprises a substantially cylindrical recess with a connector insertion opening, in which the contact element 4g is arranged.The connection point 4 comprises a base 4e on which a sealing lip 4d is formed, which is integrally formed with the elastic sealant 4b to seal a connector that can be attached to the connection point 4. This means, in particular, that the contact element 4g is sealed from the environment when the connector forms a seal with the sealing lip 4d. The first connection structure 4c is divided into individual segments 4a and is designed as an internal thread of size M12 to form a screw connection with an external thread, also of size M12, of a connector that can be attached to the connection point 4. In other words, the connection point 4 forms an M12 port. By means of such a connection, a cable having such a connector can be attached to the connection point 4 and thus to the connection module 3.Furthermore, the release mechanism 5 is shown, comprising the actuating element 5a, a return spring 5b, and two force transmission elements 5c and 5d. In the depicted state, the first connection structure 4c is in a mounting position in which a cable connector with terminal 4 could be attached. To simplify the illustration, a cable with such a connector is not shown in this view. However, such connectors would have a second connection structure in the form of an external thread that would match the internal thread of the first connection structure 4c. If the actuating element 5a were pressed with a force 9, the force transmission element 5d, which is integrally formed with the actuating element 5a, would press against the force transmission element 5c, which is designed as a ramp or plunger, with a hump-like contact contour.Due to the ramped shape of the force transmission element 5c, the force 9 of the force transmission element 5d, which is integrally formed with the actuating element 5a, would be deflected towards the base 4e. Since the ramped force transmission element 5c is force-transmittingly coupled to the base 4e, the force 9 introduced by the actuating element 5a can thus be transferred to the base 4e. If the applied pressure force on the base 4e is sufficiently large, the first connecting structure 4c is moved from the fixed position to a release position.

[0096] The force transmission element 5c is guided in the third housing part 3c, the circuit board. For this purpose, the circuit board has openings through which the force transmission element 5c passes to transfer the force to be transmitted to the base 4e. In the release position, a connector previously attached to the connection point 4 in the fastening position can be removed from the recess without any screw movement, since the screw connection is released by moving the first connection structure 4c from the fastening position to the release position. The return spring 4b is clamped between the ramp-shaped force transmission element 5c and the third housing part 3c, the support plate. The return spring 4b thus generates a restoring force that causes the force transmission elements 5c, 5d, and the actuating element 5a to return to their initial positions when the pressure force applied by the actuating element 5a is released.This allows the base 4e and the first connecting structure 4c to move from the release position back to the fastening position, this movement occurring due to the elasticity and restoring force of the segments 4a. In a modified embodiment, the ramp-shaped force transmission element 5c may have a differently or oppositely shaped ramp, designed such that the actuating element 5a must be pulled to move the first connecting structure 4c from the fastening position to the release position. This prevents accidental loosening of the connection point 4 with a connector.Alternatively, it may also be conceivable that the actuating element 5a is merely an electric button with which an electric actuator can be actuated, whereby a force can be exerted on the ground 4e with the electric actuator in order to transfer the first connecting structure 4c from the fastening position to the free position.

[0097] In Figure 3b The section view BB of the section path BB is shown. Figure 2The connection point 4 is shown in perspective. This view depicts the connection point 4 with the first connection structure 4c and the segments 4a, which are spaced apart from each other circumferentially. The slots are arranged between adjacent segments 4a and extend radially from the connector insertion opening of the recess of connection point 4 to the bottom of the recess of connection point 4. The connector insertion opening is surrounded by a circumferential collar that extends from the surface of the cover. The collar is formed by the segments and the sealant. The slots are sealed by means of the elastic sealant 4b to prevent the ingress of moisture. The sealant 4b is designed to be elastic in such a way that it allows relative movement between adjacent segments 4a.It can also be seen that the sealing lip 4d consists in one piece of the sealant 4b and is arranged at the bottom 4e of the recess of the connection point 4. The substantially cylindrical contact element 4g for electrical contact with a connector that can be attached to the connection point 4 is arranged in the recess of the connection point 4. Furthermore, the sealant 4b may have projections 4f radially spaced from the connector insertion opening, which rise from the surface of the cover of the connection module. At points where the projections 4f formed from the sealant 4b are located on the surface of the cover, the sealant 4b extends rod-like into the interior of the connection module housing. The rod-like extension of the sealant 4b into the interior of the housing preferably has a rectangular cross-section, perpendicular to the direction of extension.

[0098] In Figure 3cschematically, this is the section view CC of the section path CC from Figure 2The diagram shows a section through two opposing segments. It depicts the first connecting structure 4c in its unloaded, fixed position. The fixed position is an initial position in which no external force acts on the connection point 4, which is designed to move the first connecting structure 4c from the fixed position to the release position, thus disengaging the fastener. A first deformation point 8a is formed at the transition from the base of the connection point 4 to the cylindrical wall of the recess of the connection point 4, where the first connecting structure 4c is located. A second deformation point 8b and a third deformation point 8c are arranged radially from the recess of the connection point 4 and are spaced apart from each other in the radial direction.The deformation zones 8a, 8b, 8c are preferably formed at each of the segments of the connection point 4. The deformation zones 8a, 8b, 8c are preferably implemented as material weakenings, for example by being thinner-walled than adjacent areas or sections. Alternatively or additionally, the deformation zones 8a, 8b, 8c can be made of a material or have a material composition that is more easily deformed compared to the material of the areas adjacent to the deformation zones 8a, 8b, 8c.The deformation zones 8a, 8b, 8c ensure that when a force is applied to move the first connection structure 4c from the fastening position to the release position, these zones are elastically deformed. This allows the first connection structure 4c to move from the fastening position to the release position without any plastic deformation of the connection point 4. Furthermore, the elasticity of the deformation zones 8a, 8b, 8c ensures that after the force is released, the first connection structure 4c returns to the fastening position. This is due to a restoring force resulting from the elastic deformation of the deformation zones 8a, 8b, 8c.

[0099] In Figure 3d schematically, another section view CC of the section path CC from Figure 2The view shown corresponds to the view from Figure 3cThe difference is that this illustration shows the first connection structure 4c in the release position. In other words, in this position, the connection structure 4c would be secured to a second connection structure of a connector. The first connection structure 4c is in the release position because a force 9 is applied to the base 4e of the connection point 4 by means of the release mechanism, which is not shown here. The force 9 causes an elastic deformation of the deformation points 8a, 8b, 8c. In other words, applying the force 9 to the base 4e causes the contact element 4g to extend out of the recess of the connection point 4 and, more importantly, causes the first connection structure 4c to move from the secured position to the released position, thus releasing the connection.Here, the segments of the connection structure 4c move apart in such a way that they are no longer in contact with the second connection structure. It can also be seen that the connector insertion opening of the connection point 4 has a larger diameter in the release position than in the fastening position, in a plane perpendicular to the insertion direction of the connector into the connector insertion opening. This is due to the cylindrical wall of the recess of the connection point bulging radially outwards during the transition from the fastening position to the release position. The distance between the bottom 4e of the recess and the connector insertion opening of the recess also decreases. The curvature is simplified here by an angle α (alpha), which is shown in... Figure 3dThe angle between a perpendicular corresponding to the position of the wall of the connection point recess in the fastening position and the position of the wall in the release position is formed. When the force 9 decreases or ceases, the elasticity of the deformation points 8a, 8b, 8c and the resulting restoring force cause the first connection structure 4c to move from the release position to the fastening position. It is also possible to insert a connector in the release position into the recess of connection point 4 and then fasten the connector at connection point 4 by moving the first connection structure 4c from the release position to the fastening position. This method can save assembly time by eliminating the need for screwing. Reference sign
