It is also known, for example, to fasten such a connection device in the opening of the wall section in a snap-in manner by means of elastic fastening latch arms, as described, for example, in DE 10 2010 045 913 B4. Summary of the Invention
[0003] The object on which the present invention is based is to provide a fastening device for fastening an electrical connection device that is particularly versatile, and a device formed with such a fastening device.
[0004] The object is achieved in a fastening device of the type mentioned at the beginning in that the fastening device has at least one second fastening element by means of which the fastening device can be fastened to the object, wherein the second fastening element is configured with a different fastening functionality compared to the first fastening element. The present invention has the advantage that an electrical connection device can be fastened to one object or different objects in different ways by means of the same fastening device, for example, fastened in different spatial orientations or by means of different mounting methods. For this purpose, the fastening device has a first fastening element and a second fastening element, wherein the fastening elements are configured with different fastening functionalities, that is, configured as fastening mechanisms with different functions, for example, for latching without additional mounting elements on the one hand, and for latching by means of additional mounting elements such as bolts on the other hand.
[0005] A versatile fastening device is provided in the above-described manner, and the part variety is reduced by means of the versatile fastening device. This reduces the cost not only for the manufacturer but also for the user, for example, the cost for warehouse management.
[0006] An electrical connection device can be fastened to an object, such as a plate member and / or the housing wall of a device, for example, on a wall section of the housing wall, by means of one or more fastening devices according to the present invention. The wall section can be a part of the housing wall of the housing of an electrical or electronic device.
[0007] According to an advantageous design of the present invention, at least one first fastening element and at least one second fastening element are configured to fasten the electrical connection device to an object by means of at least one first fastening element according to the user's selection, or (alternatively) to fasten the electrical connection device to an object by means of at least one second fastening element. Thus, in terms of fastening the electrical connection device to an object, only one of the at least one first fastening element and the at least one second fastening element always functions.
[0008] According to an advantageous design of the present invention, the first fastening element is configured as a fastening latch arm that can be deflected in a spring-elastic manner (federelastisch), and by means of the fastening latch arm, the fastening device can be fastened in an opening of a wall section of the object by latching. This allows the fastening device and thus also the electrical connection device connected to the fastening device to be simply and quickly fastened to the wall section. For this purpose, in particular, no tools are required and no additional mounting elements are needed either. The fastening can be established in the manner of a bite-in connection.
[0009] According to an advantageous design of the present invention, the second fastening element is configured to fasten the fastening device to an object by means of a screwing device. If this is required, in this way, another fastening method can also be selected with the same fastening device. By means of the screwing device, the fastening device and thus the electrical connection device connected thereto can be screwed to the object. The screwing device can, for example, have a bolt and a nut.
[0010] According to an advantageous design of the present invention, the fastening device has at least two second fastening elements arranged in different spatial orientations, and by means of the at least two second fastening elements, the fastening device can be fastened to a wall section of the object in at least two different spatial orientations relative to the wall section of the object. Here, for example, at least two second fastening elements can each be configured to be fastened by means of a screwing device. In this way, the fastening device and thus the electrical connection device connected thereto can be fastened to the object in different orientations. Here, it is not necessarily required to fasten in an opening of the wall section of the object, and fastening on a continuous wall surface is also feasible. For example, the fastening device can be fastened in an opening of the wall section by means of one second fastening element, and fastened on a continuous wall surface by means of another second fastening element.
[0011] According to an advantageous design of the present invention, the second fastening element is configured in the form of one or more through-openings in the base body of the fastening device or at least one bolt support surface, through which a bolt can be guided, and the bolt head or nut of the bolt can be supported at the bolt support surface. Thereby, the fastening device has advantageously provided the basic auxiliary elements for arranging the screwing device, in particular the bolt support surface. The bolt can be guided through the through-opening, for example, with its threaded section and / or with its bolt head through the through-opening. Then, the fastening device is fastened to the object by screwing with the help of the bolt support surface and one or more through-openings using the bolt.
[0012] In particular, the through-opening can extend through the entire fastening device in the longitudinal direction, that is, through the base body. In an advantageous design, the through-openings are arranged aligned with each other in the longitudinal direction of the fastening device.
[0013] If there are a plurality of second fastening elements oriented in different spatial orientations, the plurality of second fastening elements can each have one or more through-openings of the previously mentioned type and at least one bolt support surface.
[0014] For example, in the case of one second fastening element, the through-opening can extend through the fastening device in the longitudinal direction, and in the case of another second fastening element, it extends through the fastening device perpendicular to it in the transverse direction.
[0015] According to an advantageous design of the present invention, the fastening device has a receiving chamber for receiving the bolt head or nut of the bolt guided through at least one through-opening. In this way, the bolt head or nut can be received completely or at least largely hiddenly at the fastening device, so that no additional structural space is required.
[0016] According to an advantageous design of the present invention, at least one through-opening extends through at least a part of the fastening latch arm of the fastening device, in particular through at least a part of the fastening latch arm of the fastening device in the longitudinal direction of the fastening latch arm. In this way, the bolt can also be guided completely or partially through the fastening latch arm. Thereby, the general usability of the fastening device is further improved.
[0017] According to an advantageous design of the present invention, the second fastening element has at least one threading opening with a first diameter through which the thread of the bolt can, but the bolt head cannot, be guided, and the second fastening element has at least one threading opening with a second diameter that is greater than the first diameter such that the bolt head can be guided through. Thus, the dimension of the threading opening with the first diameter is designed to be small for the bolt head. For example, the threading opening at the bolt support surface can have the first diameter. The threading opening in the fastening latch arm can have the second diameter. In this way, the bolt can be largely accommodated in the fastening device.
[0018] According to an advantageous design of the present invention, the fastening device has at least one connecting element by means of which the fastening device can be fastened to a mating connecting element that is configured as a mating part of the connecting element of the electrical connection device. This allows, for example, the simple and rapid connection of the fastening device to the electrical connection device by form-fitting and / or force-fitting. For example, the mating connecting element can be formed at the housing of the electrical connection device.
[0019] According to an advantageous design of the present invention, at least one connecting element is configured as a form-fitting connecting element that can be fastened to the mating connecting element of the electrical connection device by form-fitting. The connecting element can be configured to have an undercut, for example, an orbital profile with a dovetail profile.
[0020] According to an advantageous design of the present invention, the fastening device is configured as a plastic component, in particular a plastic injection-molded component.

[0022] The electrical connection device can, for example, have an insulating material housing. At the housing, mating fastening elements for accommodating the fastening device can be present at two housing sides facing away from each other.
[0023] According to an advantageous design of the present invention, at least two fastening devices of the type previously mentioned are fastened to the electrical connection device at sides of the electrical connection device facing away from each other. This further demonstrates the universal usability of the fastening device. Thus, multiple fastening devices of the same type can be fastened to the connection device, which further reduces part diversity. The electrical connection device can be fastened particularly stably and securely to an object by at least two fastening devices.
[0024] Advantageously, the fastening device is configured mirror-symmetrically at least with respect to a plane in the longitudinal direction. Then, two identically configured fastening devices can be fastened symmetrically to the connecting device in a simple manner.

[0042] Figure 9 The device according to Figure 7 in a third mounting type is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0043] Here, Figure 2 a side view is shown, Figure 6 a front view is shown, and the remaining drawings each show a perspective view.
[0044] Referring to Figures 1 to 4 , the design of the fastening device 10 will be explained first. The fastening device 10 has a base body 4, at which a first fastening element 1 in the form of a fastening latching arm is provided at a first end. By means of the first fastening element 1, a biting fastening can be carried out in an opening of a wall section of an object. For this purpose, the fastening latching arm preferably has a plurality of latching edges at the free end.
[0045] The fastening device 10 has a second fastening element 2 which is configured for fastening by means of a screwing device. The second fastening element 2 has a plurality of through openings 20, 21, 22, 23, 24 and a bolt support surface 25. The plurality of through openings are arranged successively and aligned in the longitudinal direction of the fastening device 10 and penetrate the base body 4. It can be seen that the first through opening 20 penetrates the fastening latch arm. The through openings 20, 21 have a larger diameter than the subsequent through openings 22, 23, 24, which enables a bolt to be inserted through the fastening device 10 in the longitudinal direction with its bolt head, such that the bolt head is supported at the bolt support surface 25 and the threaded section of the bolt extends through the further through openings 22, 23, 24.
[0046] The fastening device 10 has a further second fastening element 3 which is likewise configured for fastening by means of a screwing device. The further second fastening element 3 has one or more through openings 30 and a bolt support surface 31. The one or more through openings 30 extend in a direction orthogonal to the longitudinal direction L of the fastening device 10, i.e. likewise orthogonally to the aligned arrangement of the through openings 20, 21, 22, 23, 24. In this way, the fastening device 10 can be screwed onto an object by means of a bolt guided orthogonally to the longitudinal direction L.
[0047] For the bolt head supported at the bolt support surface 25, the fastening device 10 has a receiving chamber 26. For the bolt head supported at the bolt support surface 31, there is a further receiving chamber 32.
[0048] Furthermore, the fastening device 10 has a connecting element 5 at one side of the base body 4, on which an electrical connection arrangement can be fastened in a form - fit and / or force - fit manner.
[0049] Figure 5 An electrical connection device 11 is shown, which has mating connection elements 12 at two mutually opposite sides of its housing, and the mating connection elements are configured as mating parts of the connecting element 5 in terms of their shape. Advantageously, the connecting element 5 and the mating connection elements 12 are configured for fastening in two orientations of the fastening device 10 which are rotated 180 degrees relative to each other, i.e. the fastening device 10 can be fastened to the electrical connection device 11 selectively in the direction in which the first fastening element 1 points in the plugging direction S of the electrical connection device 11 or in the direction in which the first fastening element 1 points opposite to the plugging direction S.
[0050] Figure 6 In the upper part, it is shown how two fastening devices 10 can be fastened to the electrical connection device 11 by means of a connecting element 5 and mating connection elements 12 by means of a movement. This results in Figure 6The device 9 shown below, which has an electrical connection device 11 and optionally a fastening device 10, or two fastening devices 10 as shown, and in this way forms a structural unit that can be fastened by the user to an object.
[0051] Figure 7 Describe the first feasibility of fastening the device 9 to the wall section 8 of the device. The wall section 8 has an opening 7. The device 9 can be locked in at the two inner edges of the opening 7 by means of a first connecting element 1, namely a fastening latch arm. Thus, the device 9 is fastened to the wall section 8 in a spatial orientation in which the insertion direction S extends substantially orthogonally to the wall section 8 or orthogonally to the plane of the wall section 8.
[0052] Figure 8 Show an alternative feasibility of fastening the device 9 to the wall section 8, which again has an opening 7. In this case, fastening is carried out by means of the fastening device 10 arranged oppositely at the connection device 11, such that the second fastening element 2 is oriented towards the wall section 8 and fastening is carried out by means of a screwing device, namely by means of a bolt 13, the threaded section 15 of which is screwed to the wall section 8 by means of a nut 16. Here, the bolt head 14 of the bolt 13 bears against the corresponding bolt support surface 25 of the fastening device 10 and is received in the receiving chamber 26. Here, the insertion direction S also points in a direction orthogonal to the wall section 8.
[0053] Figure 9 Show an alternative feasibility of fastening the device 9 to the wall section 8, in which case the wall section 8 does not necessarily have to have an opening 7. In this case, the device 9 is fastened with an insertion direction S parallel to the extension of the wall section 8 or parallel to the plane of the wall section 8. For this purpose, another second fastening element 3 of the fastening device 10 is used. Fastening is again carried out by means of a screwing device, namely via a bolt 13 and a nut 16. Here, the corresponding bolt 13 is guided through the through-opening 30 and its bolt head 14 bears against the bolt support surface 31. Then, the bolt head is received in the receiving chamber 32.
