DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] The holding device 1 according to the invention holds or fixes one or more cables K, in particular a section of one or more cables K, and for this purpose is intended for placement or attachment to a section or area of ​​an application component A. The application component A can be any application component having a power supply or an electrical control, or both a power supply and an electrical control. The one or more cables K can thus be power cables, or cables for controlling the application component A, or signal cables. The application component A can be an actuator or a motor or a computer component or a housing of an actuator or a housing of a motor or a housing of a computer component. The application component A can also be an intermediate holder or intermediate piece intended to be attached to a fixture or a wall, i.e. a spatially fixed or fastened or fixed object. The application component A can also be a separate, spatially installable component.

[0036] The holding device 1 shown in FIG. 1 comprises a holder housing 10 with a cable receiving opening 14, which may in particular be realized as a through opening 15 or a recess, as shown in the drawing, and a connection device 20 for coupling the holding device to an application component A in the form of a crimp flange. In order to describe the holding device 1 and its components, a first reference axis B1 and a second reference axis B2 extending perpendicularly to the first reference axis B1 are defined herein. In the following, the cable receiving opening 14 is described as a through opening 15. The first reference axis B1 extends through the center of the cable receiving opening 14 or through opening 15, so that the through opening 15 extends along the first reference axis B1 of the holding device 1.

[0037] The cable receiving opening 14, which is realized as a recess, is designed to receive one or more end sections of the cable K. The through opening 15 is designed to accommodate one or more cables K. The one or more cables K may be designed as a single cable or as a plurality of cables or as a cable bundle. When one or more cables K are accommodated by the through opening 15, the cables K extend through the through opening 15, so that the cable receiving section K1 is located in the through opening 15. The cross section of the through opening 15 is designed with respect to its size and shape in the direction of the first reference axis B1 such that the cable receiving section K1 can be accommodated in the through opening 15. In particular, the size and shape of the through opening 15 may be designed such that there is a sufficient clearance between the inner surface of the through opening 15 and the outer surface of the one or more cables K. The size and shape of the through opening 15 may be designed such that the one or more cables K can move relative to the holder housing 10 along the first reference axis B1 and rotate around the first reference axis B1. What is important here is the size of the smallest diameter of the through opening 15 in the direction of the first reference axis B1.

[0038] The connection device 20 comprises a coupling piece 60 made of a magnetic material. The coupling piece 60 is held in the holder housing 10 and is preferably attached and fixed in or to the holder housing 10. The coupling piece 60 is provided for coupling to the application component surface section A1 of the application component A. For this purpose, as also realized in the embodiment of FIG. 1, the coupling piece 60 may only be partially arranged in the holder housing 10 and a second part of the coupling piece 60 may protrude from the holder housing 10, so that at least a part of the surface section 62 of the coupling piece 60 forms a protruding outer surface of the holding device 1, so that the coupling piece 60 partially protrudes from the holder housing 10. Alternatively to this, the holding device 1 may be realized such that the coupling piece 60 is completely arranged in the holder housing 10, i.e. does not form a protruding outer surface of the holding device 1. The surface section 62 is spherically curved. Generally, in these embodiments, the protruding surface section 62 may be convexly curved in one or more sections. The shape of the connecting piece 60 can otherwise be arbitrary and is particularly advantageously adapted to the holder housing 10 or the respective adapter part 40 .

[0039] In this case, the convex or in particular spherical curvature is formed in the direction of observation when viewed from the application component. The convex curvature of the surface portion 62 is formed in particular in the area which is the furthest away from the holder housing 10 or which includes the furthest point of the surface portion. This area can be the surrounding area of ​​the furthest point of the surface section.

[0040] In particular, the second reference axis B2 may be defined to intersect the first reference axis B1 and to extend through the center or center point of the connecting piece 60. The second reference axis B2 may also be defined in another way. For example, the second reference axis B2 may be defined to intersect the first reference axis B1 and in addition to this form a perpendicular to the application component surface section A1, which in a given initial or target orientation of the holding device 1 in the connected state may in particular be molded or selected to have a straight surface.

[0041] The coupling of the holder housing 10 or the coupling piece 60 to the surface section A1 of the application component A is carried out in such a way that the application component A in the area of ​​the application component surface section A1 can be attracted by the magnetic coupling piece 60, in particular is ferromagnetic or metallic, so that at an appropriate distance between the application component surface section A1 and the surface section 62 of the coupling piece 60 which is arranged facing the application component surface section A1, a magnetic force acts between the coupling piece 60 and the application component A due to the mutual attractive forces acting between the coupling piece 60 and the application component A. The selection of the material of the connecting piece 60, the shape of the connecting piece 60 and the position of the connecting piece 60 in the holder housing 10, which determines the distance of the connecting piece 60 from the application component surface portion A1 in the connected state, is made such that when a particular material of the application component A is used, a magnetic force generated in the connected state acts on the application component surface portion A1 and this magnetic force exceeds a predetermined minimum amount and, optionally, falls below a predetermined maximum amount, so that, on the one hand, a sufficient holding force is provided during normal use and, on the other hand, the holding force is limited and, as a result, the desired separation of the connecting piece 60 from the application component A or its surface portion A1 is provided in the event of excessive forces acting on the cable K.

[0042] In the coupled state, the surface portion 62 of the coupling piece 60 is preferably in abutting contact with the application component surface portion A1, where a section of the coupling piece 60 extends in the direction of the second reference axis B2 beyond the holder housing 10 and away from the through-opening 15. In contrast, if the coupling piece 60 is completely within the holder housing 10, then in the coupled state a predefined distance is provided between the surface portion 62 of the coupling piece 60, i.e. each point thereof, and the application component surface portion A1.

[0043] Due to the type of coupling described, the holder housing 10 is rotatable relative to the application component surface section A1 around the second reference axis B2 in the coupled state when a corresponding torque is exerted on the holder housing 10 or on one or more cables K, which causes rotation around the second reference axis B2 or comprises a component which causes rotation around the second reference axis B2, whereby in both cases the coupled state is simultaneously maintained stable by magnetic attraction.

[0044] By correspondingly selecting the material of the connecting piece 60, the shape of the connecting piece 60, and the position of the connecting piece 60 in the holder housing 10, the magnetic force generated in the connected state can be adjusted, and this magnetic force can move one or more cables K accommodated in the holder housing 10, together with the holding device 1, along the first reference axis B1, or transversely to the first reference axis B1, or along the first reference axis B1 and transversely to the first reference axis B1.

[0045] The embodiment of the holding device 1 according to Fig. 1 comprises a connecting piece 60 realized as a ball. According to the invention, the connecting piece 60 can also have other shapes in the respective embodiments of the holding device 1 defined herein. The connecting piece 60 can also be realized as an ellipsoid or as a section of an ellipsoid. In particular, the shape of the connecting piece 60 can be selected in various ways, for example according to the application or the manufacturing manner, the connecting piece 60 comprises, at least in one section, a spherical surface section whose orientation extends along the second reference axis B2 and projects away from the through opening 15, i.e. which is located facing the application component surface section A1 or is oriented towards the application component surface section A1 in the combined state.

[0046] Other shapes are also conceivable for the connecting pieces 60 in the embodiments of the holding device 1 described in this specification which are advantageous in the individual case and which are advantageous for providing the necessary mobility of the holding device 1 in the connected state, for example a pyramidal shape in at least one section, or a rectangular prism shape in at least one section, or a rhombus shape in at least one section, in each case regular or irregular.

[0047] The spherical surface section can be designed such that the holding device can rotate relative to the application component surface section A1 in the coupled state, these rotations including mutually different rotational movement components which in each case extend perpendicular to the second reference axis B2 and transversely to each other or perpendicularly to each other.

[0048] An embodiment of the holding device 1 according to the invention may comprise a connecting piece 60 formed in at least one section as a cylinder 360, with a flat base surface 362 of the cylinder 360 oriented in the direction of the second reference axis B2 or along the direction of the second reference axis B2 away from the through opening 15, i.e. with an orientation facing the application component surface portion A1 in the coupled state. In particular, a section 361 of the cylinder 360 may extend beyond the holder housing 10 in the direction of the second reference axis B2. Such an embodiment of the holding device 1 is shown in Fig. 6. Another embodiment of the holding device 1 comprises a connecting piece 60 realized in at least one section as a cylinder 360 and arranged completely in the holder housing 10.

[0049] Another embodiment of the holding device 1 comprises a connecting piece 60 which is realised in at least one section as a cylinder or partial cylinder, a section of the connecting piece 60 protruding beyond the holder housing 10 in the direction of the second reference axis B2, the surface which is directed outwards in the direction of the second reference axis B2 away from the holder housing 10 being at least a section of a side surface of the connecting piece 60. In this case, the holding device in the connected state is rotatable relative to the application component surface portion perpendicular to the second reference axis B2, in particular with a rotational movement component which includes a rotation axis extending at or along a reference axis of the connecting piece 60 which is partially surrounded by a part of the side surface of the connecting piece 60.

[0050] According to the invention, the coupling pieces 60 can be directly received by the holder housing 10 , i.e. the coupling pieces 60 can abut against one or several inner surfaces of the holder housing 10 .

[0051] The holder housing 10 can be designed in various ways and generally comprises a first receiving compartment 11 in which a through opening 15 is formed and a second receiving compartment 12 in which a connecting piece 60 is received. The first receiving compartment 11 and the second receiving compartment 11 are arranged side by side along the second reference axis B2. In particular, the holder housing 10 can be formed as a substantially closed housing with lateral openings 31, 32 formed by the outer edges of the through opening 15, the lateral openings 31, 32 being spaced apart in the direction of the first reference axis B1. In addition to this, as shown in the embodiment of Figs. 1 and 2, the holder housing 10 can comprise an opening 33 opening in the direction of the second reference axis B2, the opening 33 being formed in the second receiving compartment 12. The holder housing 10 can be designed as a hollow body, as shown in Figs. 1, 4 or 5, but does not have to be. Alternatively, the first receiving section 11 and the second receiving section 12 can each be realised in the form of a bracket or a clamp.

[0052] According to one embodiment of the invention, the holder housing 10 can be designed as a closed housing, with the exception of the opening 33 and the through opening 15. The term "closed housing" means that the housing or the side walls of the housing are made of a continuous passing material or are formed as a wall extending over the surface, with respect to a circumferential contour, and thus may not be formed of a continuous passing material, but for example a grid or the like.

[0053] The first receiving compartment 11 and the second receiving compartment 11 can be manufactured from or as one piece, as shown in the embodiment of the holding device 1 in Figures 1 and 2. The first receiving compartment 11 and the second receiving compartment 11 can also be manufactured as two separate pieces, as shown in the embodiment of the holding device 1 in Figure 4 and in the embodiment of the holding device 1 in Figure 5. In this case, the two pieces can be attached to each other in a form-fitting manner or by the connecting element 225 or 325, or alternatively by several connecting elements.

[0054] In the through opening 15 in the first receiving compartment 11 a cable receiving part 50 can be arranged, which makes it possible to hold or guide the cable section. The cable receiving part 50 can be formed in the shape of a sleeve or a tube, as shown in the embodiment of the holding device 1 in Fig. 1. The cable receiving part 50 can also be shaped in a different shape, for example as a ring, which can be attached to the through opening 15 inside the through opening 15, in particular to the first receiving compartment 11.

[0055] The connection device 20 of the embodiment of the holding device 1 according to the invention can comprise an adapter part 40, which is fixed or fastened to the second receiving compartment 12 of the holder housing 10, for example to its outer surface, edge surface or inner surface, on which the connecting piece 60 is held or fixed. In general, the connecting piece 60 can be securely held or fixed to the adapter part 40 provided according to the invention, for example by a corresponding recess in the inner wall of the adapter part 40 in which a section of the connecting piece 60 is located. Alternatively or additionally, the connecting piece 60 can be pressed into the adapter part 40, so as to fix the connecting piece 60 to the adapter part 40.

[0056] The embodiment of the holding device 1 according to FIG. 1 comprises an adapter part 40, which is in the area of ​​the second receiving section 12 and has the shape of a sleeve section, referred to in the present specification as an adapter receiving sleeve 140. On the inner wall of the adapter receiving sleeve 140, there is a connecting piece 60, which is fixed. Its central axis extends at or along the second reference axis B2. In the figure, the connecting piece 60 is spherical, but it can also have any other shape, in particular any other shape described in the present specification. The adapter receiving sleeve 140 of the embodiment of the holding device 1 according to FIG. 1 is inserted into the holder housing 10 until the end of the adapter receiving sleeve 140 comes into contact with the cable receiving part 50.

[0057] In particular, the connecting piece 60 may be realised by any shape having a curved surface portion 62, at least in one section, whose orientation extends along the second reference axis B2 and which protrudes beyond the opening 33 or its outer boundary edge at this point so as to move away from the cable receiving opening 14 as viewed from the cable receiving opening 14.

[0058] The holding device 1 can also be realized in such a way that the adapter part 40, which can be realized for example in a cylindrical shape, is realized with a bottom at the opening 33, i.e. closed, so that the connecting piece 60 does not protrude beyond the holder housing 10 and is covered on the outside. Alternatively, the holder housing 10 can be closed at this point instead of the opening 33, i.e. equipped with a cover for the connecting piece 60, which can be realized differently according to one of the embodiments described herein. In these cases, the material of the section of the adapter part 40 which covers the connecting piece 60 on the outside, or the material of the holder housing 10, is realized in such a way that the magnetic force caused by the connecting piece 60 acts through this covering section.

[0059] The embodiment of the holding device 1 according to Fig. 4 comprises an adapter part 40, which is in the region of the second receiving section 12 and which is attached to the holder housing 10, has the shape of a ring and is referred to in the present specification as an adapter receiving ring 240. Only one section of the receiving ring 240 is inserted into the holder housing 10 at the opening 33 and is screwed into the holder housing 10, for example by means of one or more corresponding threads, so that the second section 242 protrudes from the holder housing 10. The connecting piece 60 is attached to the adapter mounting ring 240. To illustrate a possible application of the holder housing 10 according to the invention, a magnet A2 is shown in Fig. 4, which can be attached to an application component A.

[0060] Also in this embodiment, the coupling piece 60 generally comprises, at least in one section, a curved surface portion 62, the orientation of which extends along the second reference axis B2, which, as viewed from the cable receiving opening 14, projects beyond the opening 33 or, in this respect, its outer boundary edge away from the cable receiving opening 14, where the convex or, in particular, spherical curvature is shaped in the direction of observation as viewed from the application component. The convex curvature of the surface portion 62 is formed in particular in an area which is the furthest area as viewed from the holder housing 10 or which includes the furthest point of the surface portion. This area may be the surrounding area of ​​the furthest point of the surface portion.

[0061] Figure 6 shows two coupling situations between the holding device 1 shown in figure 4 and an application component A realised in the form of a plate. On the surface of the application component A several application component surface sections A1 are formed, each in the form of a concave spherical recess. Independently of these, each straight surface section of the application component A can also be an application component surface section A1. The application component surface section A1 can also be realised as a convexly curved surface section, in particular as a cylindrical or partially cylindrical side surface or, for example, as a partially rhombic shaped edge line of the application component A in each case.

[0062] The embodiment of the holding device 1 according to Fig. 5 also comprises an adapter part 40, which is in the region of the second receiving compartment 12, is attached to the holder housing 10, has the shape of a ring and is referred to herein as adapter receiving ring 340. Only one section of the adapter receiving ring 340 is inserted into the holder housing 10 at the opening 33 and is screwed into the holder housing 10, for example by means of at least one corresponding thread, so that a second part 342 protrudes from the holder housing 10. The connecting piece 60 is attached to the adapter receiving ring 340, which in this embodiment of the holding device 1 is cylindrically shaped.

[0063] FIG. 1 shows the combination of a holding device 1 with an application component A designed as an intermediate piece in the form of a crimp flange. The crimp flange is designed as a bracket or clamp and comprises a connecting part A10 in a central section. The connecting part A10 consists of a magnetic material, such as a suitable steel. The connecting part A10 is realized as a cylindrical part having a flat round surface which in the connected state faces the connecting piece 60. The connecting part A1 can be omitted, in particular if at least the central section is formed from a magnetic material.

[0064] The crimp flange may for example be attached as an intermediate piece to a section of the further application component A11, at which point the crimp flange may be attached and crimped to the outside of the further application component A11.

[0065] FIG. 3 shows a crimp flange as application component A1 and an actuator as a further application component A11, the crimp flange being crimped and thus fixed onto the outside of a cylindrical outer surface section of the further application component A11.

[0066] FIG. 7 shows a perspective view of a combination of a further embodiment of an application component A in the form of a contact device 500 with a pin-shaped contact part 501 and an embodiment of a cable holder 1 according to FIG. 1. The contact device 500 generally comprises a convexly curved outer surface section 501a, in particular a pin-shaped contact part 501 and a fastening device 502, by means of which the contact device 500 is fastened to a further application component A11.

The contact device 500 can also be realised without the connecting section 507. In the embodiment shown, the fastening part 505 is exemplarily designed as a plate. In this case, the fastening part 505 can be fastened to another application component A11. In this case, the fastening part 505 can be fastened to the further application component A11, for example by means of a connecting element or by other types of fastening. The fastening part 505 can also be pin-shaped or rod-shaped or may be realized as a form-fitting part, so that it can be securely inserted into a correspondingly shaped recess of the further application component A11 and fixed thereto.

[0067] In the embodiment shown, the further application component A11 is an adjustment device, in particular a telescopically extendable adjustment device. The further application component A11 can be provided with a mounting surface A12.

[0068] The contact device 500 can also be realized in a different way. It preferably comprises a convexly curved application component surface portion A1. In particular, the application component A may be formed as a straight pin or a pin-shaped contact member 501 or a contact member 501 with a pin-shaped portion. In this case, the application component surface portion A1 is realized by a convexly curved outer surface portion 501a in the form of a cylindrical shell surface. The contact portion 501 may also be realized as a curved pin. In these cases, it may be provided that only the outer surface section of the contact piece 501 comprises a convexly curved surface section. The contact piece 501 does not have to be realized in the form of a pin or to have a pin-shaped section. Depending on the application, the contact piece 501 can also be realized at least in one section differently, for example as a plate or as an ellipsoid or sphere or as a section of such respective body, so as to provide a convexly curved application component surface section A1.

[0069] By providing a convexly curved application component surface section A1 of the application component A, the coupling of the holding device 1 according to the invention can be performed with a predefined orientation in space or with respect to the orientation of the application component A, and in addition to this, translational and / or rotational degrees of freedom can be provided in the coupled state. These provided degrees of freedom depend in particular on the shape of the coupling piece 60 of the respective embodiment of the holding device 1 according to the invention and on the shape of the convexly curved application component surface section A1. A predefined orientation of the holding device 1 relative to the contact device 500 or relative to the application component surface section A1 in the coupled state can also be achieved when coupling the holding device 1 to the contact piece 501.

[0070] In these implementations, the holding device 1 can be realized according to one of the embodiments described herein or its variants. According to a further aspect of the present invention, an electrical connection device C is provided.

[0071] Said embodiment is shown in figure 8. Figure 8 shows a perspective view of a combination of an embodiment of an application component A, which is also shown in figure 7 and is realised as an electrical contact device 500 with pin-shaped contact pieces 501, with an embodiment of a cable holder 1 according to figure 1.

[0072] Furthermore, the coupling piece 60 and the contact part 501 of the contact device 500 are made of an electrically conductive material. For the electrical connection of the cable K to the contact part 501, a section of the electrically conductive wire of the cable protrudes in its longitudinal direction from the cable sheath and is located in the through-opening 15 of the holder housing 15, the side wall of which is provided with one or more electrical contact points in contact with the coupling piece 60 via an electrical connection section, for example in the form of a conductor section. In this application, the coupling piece 60 and the contact part 501 are made of an electrically conductive material. The contact part 501 is electrically connected to an electrical functional or operating component C1. The electrical operating component C1 can be a current connecting device.

[0073] The electrical operating component C1 may also be a control component, by which a signal provided from the cable K via the contact device 500 to the operating component C1 is processed and e.g. displayed together with the operating component C1 or used, e.g. to control an application component A. In the shown example, where the application component A is a regulating device, the signal can be used by the control component to regulate the regulating device.

[0074] According to the invention, an actuator system S is also provided, as shown in Figures 7 and 8, comprising an actuator S1 and a holding device 1. The holding device 1 can be realised according to one of the embodiments described herein. The actuator S1 comprises a pin-shaped contact piece 501 having a convexly curved outer surface portion 501a and in particular the convexly curved outer surface portion 501a which is the application component surface portion A1 as defined herein. In the coupled state, the coupling piece 60 is in contact with the application component surface portion A1 in the form of the convexly curved outer surface portion 501a. [Explanation of symbols]
