Description

[0001] The invention relates to an electrical multiple socket outlet as an installation device for wall mounting, with several consumer sockets arranged in series for mains plugs of electrical consumers and a supply connection for supplying power to the consumer sockets.

[0002] Multiple electrical outlets are a common sight. They are increasingly used in new construction and renovations of buildings and apartments, with their socket inserts being installed and wired in flush-mounted boxes, which are then covered with a frame and central insert. However, it often happens that not all electrical appliances are considered during the planning phase, resulting in a lack of outlets after the completion of new construction or renovations. Furthermore, the number of electrical appliances in a household is constantly increasing. For example, the number of battery-powered devices, such as mobile phones, tablets, and laptops, is growing, and their batteries need to be plugged into an outlet to recharge. Consequently, the demand for electrical outlets is constantly rising.

[0003] To remedy this, power strips were developed that house multiple outlets for various devices in a single casing. They are equipped with a power cord for plugging into a wall socket and sometimes even a switch to interrupt the power supply. However, these power strips are generally not very aesthetically pleasing and rarely blend into a tastefully furnished room in a house or apartment. Furthermore, the power cord can easily become a tripping hazard and thus cause injuries.

[0004] Converting an existing single socket into a multi-socket outlet requires complex, skilled work that must be carried out by a qualified electrician. First, an additional hole or holes for the flush-mounted junction box(es) must be drilled into the wall using a core drill. The flush-mounted junction box(es) can then be plastered into the hole(s). Once the plaster has dried, the socket insert(s) must be wired and secured within the flush-mounted junction box(es). Finally, a central frame with the appropriate number of socket inserts is installed. As is readily apparent, the process is quite involved and takes a considerable amount of time.

[0005] A socket, in particular a multi-pole socket, is described in DE 199 32 561 A1.

[0006] The invention is based on the objective of creating an electrical multiple socket outlet of the specified type, with which a very simple and quick expansion of a single socket outlet located in a wall or the like into a socket outlet with multiple consumer sockets is possible.

[0007] This problem is solved according to the invention by an electrical multiple socket outlet with the characterizing features of claims 1 and 2.

[0008] Advantageous further developments of the invention are characterized in the respective dependent claims.

[0009] According to the invention, in a first embodiment, the multiple socket outlet comprises a housing consisting of a back panel element and a frame element that can be attached to and secured to the back panel element. On the side of the back panel element facing the frame element, conductors for connecting the consumer sockets are provided inside the housing. The power supply connection is formed by contact pins located on the rear side of the back panel element, away from the frame element, in the area of ​​one of the consumer sockets. These contact pins protrude beyond the rear side of the back panel element and, after the multiple socket outlet is inserted into a socket insert installed in a flush-mounted box and connected to the mains power supply, make contact to supply power to the consumer sockets of the multiple socket outlet.The relatively flat housing allows the design to be adapted to existing switch and plug programs, so that after the installation of the multi-socket outlet it does not differ from the already installed sockets and a harmonious picture results.

[0010] In a further embodiment, the multiple socket outlet according to the invention also has a housing consisting of a back panel element and a frame element that can be attached to and fastened onto the back panel element. Furthermore, conductors for connecting the consumer sockets are provided inside the housing on the side of the back panel element facing the frame element. In contrast to the first embodiment, the power supply connection is formed by a socket insert arranged on the frame element in the area of ​​one of the consumer sockets. This socket insert is in contact with the respective conductors and projects beyond the rear side of the back panel element, away from the frame element. After connection to the mains power supply by inserting or fastening the conductors of a supply cable and inserting the socket insert into a flush-mounted box, it is in contact with the consumer sockets of the multiple socket outlet to supply power.Here too, the relatively flat housing allows the design to be adapted to existing switch and plug programs, whereby after the installation of the multi-socket outlet it does not differ from the already installed sockets and a harmonious picture is not spoiled.

[0011] Preferably, the conductors can be designed as rails. This facilitates their installation inside the housing, with the rails clamped between the back panel and the frame. Since the back panel and frame are preferably made of plastic, this provides insulation for the individual conductors.

[0012] The conductors can be arranged on the side of the rear panel element facing the frame element, and the conductors may have angled contact lugs and / or contact elements for connecting the consumer sockets and the power supply connection, which may extend into or through the rear panel element. The contact lugs and / or contact elements enable a simple, quick, and secure connection between the consumer sockets and between the consumer sockets and the power supply connection.

[0013] The conductor forming the phase conductor and the conductor forming the neutral conductor can each be arranged parallel to each other and spaced apart on the rear panel element, with the contact tabs and / or contact elements for connecting the consumer sockets extending into bores for the contact pins of the mains plugs and the contact tabs and / or contact elements for connecting to the phase conductor or neutral conductor of the supply connection extending through openings in the rear panel element.

[0014] In a first embodiment, the conductor forming the protective conductor can be essentially U-shaped and arranged around the phase conductor and the neutral conductor on the rear wall element, wherein the contact lugs for connection to the protective conductor of the supply connection can extend through openings in the rear wall element, and wherein earthing brackets extending to the frame element can be provided at the edge of the protective conductor for the consumer sockets.

[0015] In a further embodiment, the conductor forming the protective conductor can be designed in two parts, with the phase conductor and the neutral conductor arranged parallel to and spaced apart from the two parts of the protective conductor on the rear panel element. The contact lugs for connection to the protective conductor of the supply connection can extend through an opening in the rear panel element, and here too, grounding clips extending to the frame element for the consumer sockets can be provided at the edge of the protective conductor.

[0016] On the side of the back panel element facing the frame element, a protective cover may be provided to cover the conductors; this cover is permanently attached to the back panel element. The protective cover ensures that the live contacts are not freely accessible when the frame element is removed, thus preventing injuries from electric shocks.

[0017] The contact pins of electrical appliances' mains plugs, after being inserted into the appliance's socket, can rest against the contact tabs and / or contact elements of the phase conductor on the one hand and against the contact tabs and / or contact elements of the neutral conductor on the other. The contact tabs are angled or the contact elements are designed in such a way that they exert slight pressure on the contact pins of the mains plugs. The contact tabs and / or contact elements extend essentially along the length of the contact pins. The spring-like design of the contact tabs and / or contact elements ensures that they return to their original position after the electrical appliance's mains plugs are removed, and that this position remains permanently in place.Furthermore, the spring-loaded design of the contact tabs and / or contact elements ensures a secure contact of the mains plug and a secure hold in the consumer slots after the mains plugs are inserted into the consumer slots.

[0018] The frame element can have molded openings on its front side, facing away from the rear panel element, in the area of ​​the consumer sockets, for receiving central inserts for the mains plugs of electrical consumers, each of which can be fastened by means of a screw penetrating a central bore of the central inserts with a threaded bore provided in the rear panel element.

[0019] In the area of ​​the additional sockets, at least one through-hole penetrating the rear panel can be provided for a mounting screw to permanently attach the power strip to a wall. For this purpose, aligning holes are drilled into the wall, and then wall plugs are inserted into the holes. These, in conjunction with the mounting screws, ensure a secure hold of the power strip to the wall. The holes are located in the area of ​​the central inserts and are freely accessible after removing the inserts from the frame.

[0020] On the rear panel element, facing away from the frame element, two hollow cylindrical protrusions for receiving the power plug pins of electrical devices can be integrally molded in the area of ​​the additional power outlets. The free end of each hollow cylindrical protrusion can be closed by an integrally molded cover. These protrusions allow the housing to be very flat while simultaneously ensuring that the power plug pins can penetrate deeply enough into the power outlets. The cover insulates the contact pins. Here, too, synchronized holes are drilled into the wall into which the protrusions can be inserted.

[0021] Preferably, a drilling template can be provided for drilling the holes for the dowels and the holes for the bosses.

[0022] In the area of ​​the additional consumer sockets, as an alternative to the aforementioned fastening method, but less preferably, at least one through-hole penetrating the cover of the hollow cylindrical extensions for a fastening screw can be provided for permanently fixing the multiple socket to a wall. Preferably, after the multiple socket has been fixed to the wall, an insulator should be inserted into the opening of the extensions to insulate the screw head from the contact pins.

[0023] The area of ​​the consumer socket containing the contact pins or the socket insert can be rotatable around a rotation axis perpendicular to the longitudinal axis of the housing for horizontal or vertical mounting of the multiple socket.

[0024] The back panel element can have a recess on its rear side, facing away from the frame element, in the area of ​​the consumer socket with the contact pins, to accommodate a mounting frame for the socket insert. This recess allows the back panel element, and thus the multiple socket, to sit flush against the wall, so that no visible gap exists between the wall and the back panel element or the multiple socket.

[0027] In the following description of preferred embodiments, identical reference numerals denote identical or comparable components.

[0028] The in Fig. The embodiments of electrical multiple sockets 1 shown in Figures 1 to 13 and 14 to 18 as installation devices for wall mounting are intended for the simple expansion of single sockets 2 installed in walls to multiple sockets, wherein the multiple sockets 1 have several consumer sockets 3 arranged in series for mains plugs 4 of electrical appliances and a supply connection 5 for supplying power to the consumer sockets 3. In the Fig. The embodiments shown in Figures 1 to 13 and 14 to 18 depict multiple socket outlets 1 with a total of three consumer sockets 3. It goes without saying that the multiple socket outlets 1 can also be equipped with more or fewer consumer sockets 3.

[0029] The multiple socket outlets 1 each consist of a housing 6 with a back panel element 7 and a frame element 8 that can be attached to and fastened onto the same. The housing 6 is essentially so flat that its design can be very easily adapted to existing switch and plug ranges from manufacturers.

[0030] On the side 9 of the rear wall element 7 facing the frame element 8, conductors 11, 12, 13, preferably designed as rails, are provided inside 10 of the housing for connecting the consumer sockets 3. The supply connection 5 is, in the first embodiment ( Fig. 1 to 13) by contact pins 15 on the rear side 14 of the rear panel element 7, facing away from the frame element 8, in the area of ​​one of the consumer sockets 3, which are in contact with the respective conductors 11, 12, 13, wherein the contact pins 15 protrude beyond the rear side 14 of the rear panel element 7, facing away from the frame element 8, and, after the multiple socket 1 is inserted into a socket insert 17 installed in a flush-mounted box 16 and connected to the mains, are in contact for supplying power to the consumer sockets 3 of the multiple socket 1.

[0031] On the side 9 of the rear panel element 7 facing the frame element 8, the conductors 11, 12, 13 can each be inserted into grooves 18, 19, 20, wherein the conductors 11, 12, 13 have angled contact lugs 21, 22 for connecting the consumer sockets 3 to each other and to the supply connection 5, which extend in or through the rear panel element 7 (see in particular Fig. 6 and Fig. 7) The grooves 18, 19, 20 ensure that the conductors 11, 12, 13 are fixed in position. It goes without saying that the position fixing of the conductors 11, 12, 13 can be designed differently.

[0032] The phase conductor 11 and the neutral conductor 12 are arranged parallel to each other and spaced apart in the grooves 18, 19 of the rear panel element 7. For connecting the consumer sockets 3, the contact lugs 21 extend into bores 23 for the contact pins 24 of the mains plugs 4, with the contact lugs 22 extending through openings 25 of the rear panel element 7 for connection to the phase conductor and neutral conductor of the supply connection 5.

[0033] The conductor 13 forming the protective conductor is essentially U-shaped and runs around the phase conductor 11 and the neutral conductor 12 in the grooves 20 of the rear panel element 7. The contact lugs 22 for connection to the protective conductor of the supply connection 5 extend through openings 25 of the rear panel element 7. Earthing brackets 26 extending to the frame element 8 are provided at the edge of the protective conductor 13 for the consumer sockets 3.

[0034] After the mains plugs 4 are inserted into the consumer sockets 3, the contact pins 24 of the mains plugs 4 of the electrical devices rest against the contact tabs 21, 22 of the phase conductor 11 on the one hand and against the contact tabs 21, 22 of the neutral conductor 12 on the other. The contact tabs 21, 22 are angled such that they exert slight pressure on the contact pins 24 of the mains plugs 4. As previously described, the contact tabs 21, 22 extend essentially in the longitudinal direction of the contact pins 24. The spring-like design of the contact tabs 21, 22 ensures that they return to their original position after the mains plugs 4 of the electrical devices are unplugged, and that this position remains permanently in place (see in particular...). Fig. 13).

[0035] To ensure that the rear panel element 7 or the housing 6, and thus the multiple socket outlet 1, sits flush against the wall after installation, the rear panel element 7 has a recess 27 on its rear side 14, facing away from the frame element 8, in the area of ​​the consumer socket 3 which has the contact pins 15. This recess is designed to receive a mounting frame 28 for the socket insert 17, into which the mounting frame 28 is completely inserted (see Fig. 5 and Fig. 11).

[0036] In the second embodiment ( Fig. 14 to 18) The supply connection 5 is formed by a socket insert 17 arranged on the frame element 8 in the area of ​​one of the consumer sockets 3, which is in contact with the respective conductors 11, 12, 13 and projects beyond the rear side 14 of the back panel element 7, facing away from the frame element 8. After connection to the mains power supply by inserting or securing conductors 41, 42, 43 of a supply cable 44 in openings 45 of the socket insert 17 for clamping the conductors 41, 42, 43, and inserting the socket insert 17 into a flush-mounted box 16, the socket insert 17 is in contact for supplying power to the consumer sockets 3 of the multiple socket 1. The socket insert 17 is held securely in the flush-mounted box 16 by fastening claws 46 provided on the socket insert 17.

[0037] On the side 9 of the rear wall element 7 facing the frame element 8, the conductors 11, 12, 13, designed as rails, are arranged in a fixed position and have angled contact lugs 22 for connection to the supply connection 5 and contact elements 47 for connection to the consumer sockets 3, which extend in or through the rear wall element 7 (see in particular Fig. 17).

[0038] The conductor 11 forming the phase conductor and the conductor 12 forming the neutral conductor are also arranged parallel longitudinally and spaced apart from each other on the rear wall element 7, wherein the contact elements 47 for connecting the consumer sockets 3 extend into bores 23 for the contact pins 24 of the mains plugs 4 and the contact tabs 22 extend through an opening 48 of the rear wall element 7 for connection with the phase conductor or neutral conductor of the supply connection 5.

[0039] In the second embodiment, the conductor 13 forming the protective conductor is designed in two parts, wherein the phase conductor 11 and the neutral conductor 12 are arranged parallel to and spaced apart from the two parts 13a and 13b of the protective conductor 13 on the rear panel element 7, with the contact lugs 22 extending through the opening 48 of the rear panel element 7 for connection to the protective conductor of the supply connection 5. Earthing brackets 26 extending to the frame element 8 are provided at the edge of the protective conductor 13 and its two parts 13a and 13b for the consumer sockets 3.

[0040] After the mains plugs 4 are inserted into the consumer sockets 3, the contact pins 24 of the mains plugs 4 of the electrical devices rest against the contact elements 47 of the phase conductor 11 on the one hand and against the contact elements 47 of the neutral conductor 12 on the other. The contact elements 47 are designed such that they exert slight pressure on the contact pins 24 of the mains plugs 4. The contact elements 21, 22 extend longitudinally along the contact pins 24. The spring-like design of the contact elements 47 ensures that, on the one hand, the contact pins 24, and thus the mains plugs 4, are held securely in the consumer sockets 3, and on the other hand, that they return to their original position after the mains plugs 4 of the electrical devices are removed, and that this remains the case permanently (see in particular Fig. 17).

[0041] On the side 9 of the rear wall element 7 facing the frame element 8, a protective cover 49 is provided which covers the ladders 11, 12, 13 and is preferably permanently connected to the rear wall element 7 (see Fig. 17). Such a protective cover 49 can of course also be used with the multiple socket outlet 1 according to the first embodiment.

[0042] To ensure the formation of a relatively flat housing 6 for the multi-socket outlet 1 according to both embodiments, two hollow cylindrical projections 29 are integrally formed on the rear side 14 of the back panel element 7, facing away from the frame element 8, in the area of ​​the additional consumer sockets 3. The contact pins 24 of the mains plugs 4 of electrical devices can be inserted into these projections. To insulate the contact pins 24, the free end 30 of each hollow cylindrical projection 29 is closed by means of an integrally formed cover 31. To insert the hollow cylindrical projections 29 with the cover 31 into the wall, corresponding holes 32 only need to be drilled into the wall before mounting the multi-socket outlet 1 (see in particular...). Fig. 5, Fig. 8, Fig. 9, Fig. 17 and Fig. 18).

[0043] To ensure a secure fit of the multiple socket outlet 1 in the supply connection 5 and on the wall, preferably at least one through-hole 33 penetrating the rear panel element 7 for a fastening screw 34 is provided in the area of ​​the other consumer sockets 3 for permanently fixing the multiple socket outlet 1 to a wall, wherein the fastening screw 34 is screwed into the wall with the aid of a dowel.

[0044] Alternatively, in the area of ​​the additional consumer sockets 3, at least one through-hole penetrating the cover 31 of the hollow cylindrical extensions 29 can be provided for a mounting screw to permanently attach the multiple socket 1 to a wall (not shown). After the multiple socket has been attached to the wall, an insulator should be inserted into the opening of the extensions 29 to insulate the screw head from the contact pins 24.

[0045] After the multi-socket outlet 1 has been fully attached to the wall, openings 36 formed in the frame element 8 on its front side 35, facing away from the rear panel element 7, in the area of ​​the consumer sockets 3, are closed by means of central inserts 37 for the mains plugs 4 of electrical devices. A screw 39 penetrates a central bore 38 of each central insert 37, which can be screwed into and held in a threaded bore 40 located on the rear panel element 7.

[0046] For horizontal or vertical mounting of the multiple socket outlet 1, the area of ​​the consumer socket 3 having the contact pins 15 can be rotatable about an axis of rotation perpendicular to the longitudinal axis of the housing 6 (not shown).

[0047] All features mentioned in the preceding description and in the claims can be combined in any selection with the features of the independent claims. The disclosure of the invention is therefore not limited to the described or claimed combinations of features; rather, all combinations of features meaningful within the scope of the invention are to be considered disclosed.
