Description

[0001] The present invention relates to an electrical installation device designed according to the preamble of the main claim.

[0002] These electrical installation devices are used in buildings and are available in various forms, such as plugs, sockets, switches, push buttons, dimmers, motion detectors, and so on. For proper installation on or in a wall, these devices often have a mounting bracket, usually frame-like or plate-shaped. This allows for easy attachment of the devices to a junction box. The key design elements of these devices are often connected to the mounting bracket via a snap-fit ​​connection.

[0003] German patent DE 10 2017 109 909 B3 discloses an electrical installation device for building installation technology that corresponds to the preamble of the main claim. In this electrical installation device, the functional module can be securely and precisely fixed to a wall and / or a standard junction box by means of a carrier. The carrier can be operatively connected to a central design element, whereby first locking elements molded onto the central design element engage with second locking elements molded onto the carrier. However, this type of design cannot always meet the diverse requirements arising from the various designs of electrical installation devices.

[0004] Furthermore, DE 10 2012 109 885 B3 discloses an electrical installation device which has a support for secure and positionally accurate fixing. To create an electrical installation device that allows for simple and correct installation with automatic height adjustment or "plaster / wallpaper compensation" even when installed directly on a wall, the housing of the functional module has an intermediate frame. This intermediate frame is provided with at least one guide track in which a sliding piece, designed as a fastening element, is slidably mounted. This sliding piece, which holds the functional module to the support, interacts with a fastening element present on the support.

[0005] Furthermore, it is known from US 2004 / 0257181 A1 to provide adapter pieces on at least one of its two main surfaces with stiffening ribs, which are arranged in a truss-like manner.

[0006] Furthermore, DE 20 2004 005 837 U1 discloses a surface-mounted switch housing for accommodating an electronic module, comprising at least one module housing, onto which at least one rocker switch can be mounted. At least one intermediate frame is provided, which can be connected to at least one base plate. A fully assembled state is achieved when all elements are connected to each other in the sequence rocker switch, module housing, intermediate frame, and base plate.

[0007] Starting from such a designed electrical installation device, the present invention aims to create an electrical installation device whose central design element can be attached to its support in a particularly simple manner, while simultaneously ensuring a reliable functional connection between the central design element and the support over a particularly long period of time.

[0008] According to the invention, this problem is solved by the features specified in the main claim.

[0009] A particular advantage of this type of design is that the use of adapter pieces allows for the simple and cost-effective fulfillment of diverse requirements arising from the various designs of electrical installation devices. Furthermore, the central design elements can be easily removed from the carrier as needed, without risk of damage.

[0010] Further advantageous embodiments of the invention are specified in the dependent claims. The invention will be explained in more detail using several exemplary embodiments. These show: Fig. 1: In principle, an electrical installation device, shown spatially in an oblique top view, as an exploded view (first embodiment); Fig. 2: In principle, the adapter piece, as in Fig. 1 shown, according to the first embodiment, spatially in oblique top view, in enlarged view; Fig. 3: In principle, the adapter piece, as in Fig. 1 shown, according to the first embodiment, spatially in oblique bottom view, in enlarged view; Fig. 4: in principle an electrical installation device, spatially in oblique top view, as an exploded view (second embodiment); Fig. 5: In principle, the adapter piece, as in Fig. 4 shown, according to the second embodiment, spatially in an oblique top view; Fig. 6: In principle, the adapter piece, as in Fig. 4 shown, according to the second embodiment, spatially in an oblique bottom view; Fig. 7: in principle an electrical installation device, spatially in oblique top view, as an exploded view (third embodiment); Fig. 8: basically the adapter piece, as in Fig. 7 shown, according to the third embodiment, spatially in an oblique top view; Fig. 9: basically the adapter piece, as in Fig. 7 shown, according to the third embodiment, spatially in an oblique bottom view.

[0011] As can be seen from the figures, such an electrical installation device essentially consists of a functional module 1, which can be securely and precisely fixed to a standard electrical box by means of a carrier 2. The carrier 2 is connected to several first locking elements 3, which engage with corresponding second locking elements 4 located on a central design element 5 of the electrical installation device attached to the carrier 2. The second locking elements 4 can be designed as needed, for example, as recesses, undercuts, locking edges, locking hooks, and so on. An adapter piece 7 is screwed to the carrier 2 via an interposed design frame 6, with the first locking elements 3 being integrally formed on the adapter piece 7.The adapter piece 7 has a clearance 8 in the area of ​​at least one first locking element 3 to allow independent movement for different adapter areas 7a, 7b. For example, the electrical installation devices can be designed as plugs, sockets, motion detectors, key card switches and the like.

[0012] In the Fig. In the first embodiment shown in 1 to 3, the functional module 1 is designed as a so-called "data socket". As can be seen in particular from Fig. As shown in Figure 1, the functional module 1 has two data connector sockets 9. The two data connector sockets 9 are held in place by the carrier 2 and thus fixed in position on it. Using two screws 10 and with the design frame 6 interposed, the adapter piece 7 is screwed to the carrier 2. This precisely fixes both the design frame 6 and the adapter piece 7 in position on the carrier 2.

[0013] As can be seen particularly from the Fig. 2 and Fig. As shown in Figure 3, the adapter piece 7 according to the first embodiment has two opposing first locking elements 3, which are designed as classic locking hooks and which project like a nose from the main surface of the adapter piece 7 facing away from the carrier 2. Each of the two first locking elements 3 of the adapter piece 7 is associated with a clearance 8 to allow independent movement for the two first adapter areas 7a, to which the first locking elements 3 are integrally formed, and the second adapter area 7b, which has the two through-holes 11 for the two screws 10. This means that the two first adapter areas 7a can move to a certain extent independently of the second adapter area 7b.The screw forces of the screws 10 assigned to the two through-openings 11 thus act essentially on the second adapter section 7b of the adapter piece 7, which is why the deformations of the adapter piece 7 caused by the screw forces occur essentially at the second adapter section 7b. As can be seen further from the . Fig. 2 and Fig. As can be seen from Figure 3, the adapter piece 7 is provided with numerous stiffening ribs 12 on its main surface facing the support 2 in order to cause the deformation to occur specifically at the second adapter section 7b. The second adapter section 7b has several stiffening ribs 12 on its main surface facing the support 2, which have a truss-like arrangement. Such truss-like arrangement of stiffening ribs 12 leads to an increase in the surface stiffness of the second adapter section 7b. For the same purpose, the second adapter section 7b of the adapter piece 7 is provided with two integrally formed hollow ribs 13 on its main surface facing away from the support 2. The two hollow ribs 13 are attached opposite each other at an edge region of the adapter piece 7 and its second adapter section 7b, respectively. As can be seen further, in particular from the Fig. 2 and Fig. As can be seen from Figure 3, the four corner regions of the adapter piece 7 are provided with both material protrusions 14 and material reductions 15 to prevent deformation at the corner regions that could be caused by the screw forces. The material protrusions 14 are integrally formed in the corner region on the main surface of the adapter piece 7 facing away from the support 2 and each has a knob-like structure. The material reductions 15 are provided in the vicinity of the material protrusions 14 and essentially directly affect the four corners of the adapter piece 7. As already described, in this first embodiment, two screws 10 are provided for screwing the adapter piece 7 to the support 2. Each screw is associated with a through-hole 11 located in the second adapter region 7b of the adapter piece 7.In the area of ​​the two through-openings 11, several plastically deformable height compensation elements 16 are located on the main surface facing the support 2. These are provided for height compensation when the adapter piece 7 is screwed to the associated support 2. As already described, the first two locking elements 3 are designed as locking hooks. These are integrally formed near an edge region on the adapter piece 7 or its second adapter section 7a and have a recessed arrangement and shape from this edge region. To achieve the intended locking forces, for example, light locking or heavy locking, a cavity 17 is formed in the main surface facing the support 2 in the area of ​​the first locking elements 3. The two first locking elements 3 each interact with a second locking element 4 located on the central design piece 5, which is designed as an undercut.

[0014] In the Fig. In the second embodiment shown in Figures 4 to 6, the functional module 1 is designed as a so-called "USB connector socket". As can be seen in particular from Fig. As shown in Figure 4, the functional module 1 has two USB connection sockets 18. The two USB connection sockets 18, or the functional module 1, are held in contact with the carrier 2 and thus positioned correctly on it. Using a screw 10 and with the design frame 6 interposed, the adapter piece 7 is screwed to the carrier 2. This precisely positions both the design frame 6 and the adapter piece 7 on the carrier 2.

[0015] As can be seen particularly from the Fig. As shown in Figures 5 to 6, the adapter piece 7, according to the second embodiment, has two opposing first locking elements 3, which are designed as classic locking hooks and which project like a nose from the main surface of the adapter piece 7 facing away from the carrier 2. A clearance 8 is associated with one of the two first locking elements 3 of the adapter piece 7 to allow independent movement for a first adapter area 7a, on which the associated first locking element 3 is integrally formed, and a second adapter area 7b, which has the through-opening 11 for the associated screw 10. This means that the first adapter area 7a can move to a certain extent independently of the second adapter area 7b.The screw forces of the screw 10 associated with the through-opening 11 thus act essentially on the second adapter section 7b of the adapter piece 7, which is why the deformations of the adapter piece 7 caused by the screw forces occur essentially at the second adapter section 7b. As can be seen further from the . Fig. 5 and Fig. As can be seen from Figure 6, the adapter piece 7 is provided with numerous stiffening ribs 12 on its main surface facing the support 2 in order to cause the deformation to occur specifically at the second adapter area 7b. The second adapter area 7b has several stiffening ribs 12 on its main surface facing the support 2, which have a truss-like arrangement. Such truss-like arrangement of stiffening ribs 12 leads to an increase in the surface stiffness of the second adapter area 7b. For the same purpose, the second adapter area 7b of the adapter piece 7 is provided with two integrally formed hollow ribs 13 on its main surface facing away from the support 2. The two hollow ribs 13 are attached opposite each other on an edge region of the adapter piece 7 and its second adapter area 7b, respectively. As can be seen further, in particular from the Fig. 5 and Fig. As can be seen from Figure 6, the four corner regions of the adapter piece 7 are provided with both material protrusions 14 and material reductions 15 to prevent deformations at the corners that could be caused by the screw forces. The material protrusions 14 are integrally formed on the main surface of the adapter piece 7 facing away from the support 2 in the corner region and each has a knob-like structure. The material reductions 15 are provided in the vicinity of the material protrusions 14 and essentially directly affect the four corners of the adapter piece 7. As already described, a screw 10 is provided for attaching the adapter piece 7 to the support 2 in this second embodiment. This screw is associated with a through-hole 11 located in the second adapter region 7b of the adapter piece 7. In the area of ​​the through-hole 11, several plastically deformable height compensation elements 16 are located on the main surface facing the support 2.These are provided for height compensation when screwing the adapter piece 7 to the associated support 2. As already described, the first two locking elements 3 are designed as locking hooks. These are integrally formed near an edge region of the adapter piece 7 or its second adapter section 7a and have a recessed arrangement and shape relative to this edge region. To achieve the intended locking forces, for example, light locking or heavy locking, a cavity 17 is formed in the main surface facing the support 2 in the area of ​​the first locking elements 3. The two first locking elements 3 each interact with a second locking element present on the central design piece 5 – not shown for the sake of simplicity – which is designed as an undercut.

[0016] In the Fig. In the third embodiment shown in Figures 7 to 9, the functional module 1 is designed as a so-called "audio connection box" 19. As can be seen in particular from Figures 7 to 9. Fig. As shown in Figure 7, the functional module 1 has four connection slots, which are intended, for example, for connecting loudspeakers. The audio connection box 19, or the functional module 1, is held in place by the carrier 2 and thus operatively connected to it, or rather, positioned precisely on it. Using a screw 10 and with the design frame 6 interposed, the adapter piece 7 is screwed to the carrier 2. This precisely positions both the design frame 6 and the adapter piece 7 on the carrier 2.

[0017] As can be seen particularly from the Fig. As shown in Figures 8 to 9, the adapter piece 7, according to the third embodiment, has two opposing first locking elements 3, which are designed as comparatively long locking tabs and project like noses from two opposing edge regions of the adapter piece 7. The two first locking elements 3, designed as locking tabs, each have a swan-neck-shaped cross-section. Each of the two first locking elements 3 of the adapter piece 7 has a corresponding recess 8 to allow independent movement for a first adapter region 7a, on which the associated first locking elements 3 are integrally formed, and a second adapter region 7b, which has the through-opening 11 for the associated screw 10. This means that the first adapter region 7a can move to a certain extent independently of the second adapter region 7b.The screw forces of the screw 10 associated with the through-opening 11 thus act essentially on the second adapter section 7b of the adapter piece 7, which is why the deformations of the adapter piece 7 caused by the screw forces occur essentially at the second adapter section 7b. As can be seen further from the . Fig. 5 and Fig. As can be seen from Figure 6, the adapter piece 7 is provided with numerous stiffening ribs 12 on its main surface facing the support 2 in order to cause the deformation to occur specifically at the second adapter area 7b. The second adapter area 7b has several stiffening ribs 12 on its main surface facing the support 2, which have a truss-like arrangement. Such truss-like stiffening ribs 12 lead to an increase in the surface stiffness of the second adapter area 7b. For the same purpose, the second adapter area 7b of the adapter piece 7 is provided with a U-shaped rib structure 20 on its main surface facing away from the support 2. The rib structure 20 is assigned to three edge regions of the adapter piece 7. As can be seen further, in particular from the Fig. 8 and Fig.As shown in Figure 9 and as already described, a screw 10 is provided for attaching the adapter piece 7 to the support 2 in this third embodiment. This screw is associated with a through-opening 11 located in the second adapter section 7b of the adapter piece 7. In the area of ​​the through-opening 11, several plastically deformable height compensation elements 16 are located on the main surface facing the support 2. These are provided for height compensation when the adapter piece 7 is screwed to the associated support 2. As also already described, the first two locking elements 3 are designed as locking tabs. These are each integrally formed on an edge region of the adapter piece 7 and have a protruding arrangement and shape.The first two locking devices 3 each interact with a second locking device present on the central design piece 5 - not shown for the sake of simplicity - which is designed as an undercut.

[0018] This results in electrical installation devices where the central design element can be attached to its support in a particularly simple manner. At the same time, a reliable connection between the central design element and the support is ensured for a particularly long period of time.

[0019] Advantageously, the use of adapter pieces provides a simple and cost-effective way to meet the diverse requirements of different electrical installation devices. Furthermore, the central design elements can be easily removed from the carrier if needed, without risk of damage.
