DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) The device 1 shown in FIG. 1 serves for the electrification of furniture and comprises a furniture panel 2, which has, in the upper panel side 2a here, two parallel grooves 3a, 3b and two exposed busbars 4a, 4b laid therein, and a plug 5 for electrically connecting to the two busbars 4a, 4b. Fastening bores 6 for fastening the furniture panel 1 are arranged centrally between the two grooves 3a, 3b.

(12) As shown in FIG. 2a, the two grooves 3a, 3b extend parallel to, and directly along, the panel end face 7 of the first furniture panel 2. The busbars 4a, 4b are each formed as a U-shaped rail profile, whereof the profile opening faces towards the upper panel side 2a, and are clamped and clawed in the grooves 3a, 3b. The free profile ends of the U-shaped rail profile are spaced from the groove walls and are thus mounted to be outwardly resilient. The U-shaped rail profiles are therefore designed such that, on the one hand, they are resiliently mounted and, on the other, become clawed in the grooves 3a, 3b as they are incorporated therein owing to the structural design.

(13) As shown in FIG. 2b, the furniture panel 2 can also have mutually angled pairs of parallel grooves 3a, 3b which lead into one another. The busbars 4a, 4b of grooves leading into one another are each connected to one another in an electrically conductive manner by means of an electrically conductive connecting element 8 (e.g., a metal angle bracket), which is inserted into the profile openings of the busbars 4a, 4b.

(14) The plug 5 has two electrical contacts 9, 10 (FIGS. 3a, 3b, 5), which are formed as exposed collector contacts 9a, 10a on a connecting side 11a of the plug housing 11 and as connection contacts 9b, 10b on a front side 11b of the plug housing 11. The connecting side 11a and the front side 11b lie opposite one another.

(15) FIGS. 4a, 4b show the assembly of the plug 5 in the furniture panel 2. The plug 5 is inserted into a bore 12, interrupting the two grooves 3a, 3b, in the upper panel side 2a of the first furniture panel 2 until the collector contacts 9a, 10a lie against the two busbars 4a, 4b in an electrically conductive manner (FIG. 5). The bore 12 is arranged eccentrically with respect to the two grooves 3a, 3b, wherein the outer groove 3b is merely at a tangent to the bore 12 with its outer groove side wall. The bore 12 can be positioned variably along the grooves 3a, 3b or busbars 4a, 4b according to customer requirements. The plug 5 closes the bore 12 entirely and terminates flush with the upper panel side 2a. The resilient free profile ends of the U-shaped rail profile are spread apart elastically by the collector contacts 9a, 10a, which results in a greater contact pressure. To this end, the collector contacts 9a, 10a preferably have a contact end reaching between the free profile ends of the U-shaped rail profile, which contact end can be configured in the form of a partial cylinder, in the form of a spherical cap, conically, in the form of a wedge or as a round or flat pin, etc. The plug 5 is covered by a seated, second furniture panel 22, except for the connection contacts 9b, 10b.

(16) A second device 21 for the electrification of two furniture panels 2, 22 is shown in FIG. 6. As in FIG. 1, the first furniture panel 2 has two parallel grooves 3a, 3b and two busbars 4a, 4b laid therein. The second furniture panel 22 lies against the upper panel side 2a of the first furniture panel 1 with its end face 23 and is fastened to the first furniture panel 2 via connecting means (not shown), which are anchored in the fastening bores 6 of the first furniture panel 2. The fastening bore 6 can be, for example, a blind hole for a dowel or connector stud; alternatively, the connection can also be configured without fastening bores, e.g., using angle brackets or Lamello connectors. The second furniture panel 22 covers the grooves 3a, 3b so that the busbars 4a, 4b are not visible from the outside. A plug 24 for electrically connecting to the two busbars 4a, 4b of the first furniture panel 2 is inserted into a bore 25 in the front panel side 22a here of the second furniture panel 22, which bore is open towards the end face 23.

(17) As shown in FIGS. 7a, 7b, 9, the plug 24 has two electrical contacts 26, 27, which are formed as exposed collector contacts 26a, 27a on a connecting side 28a of the plug housing 28 and as partially cylindrical connection contacts 26b, 27b on a front side 28b of the plug housing 28. The connecting side 11a and the front side 11b are aligned at a right angle to one another. The plug 24 closes the bore 25 entirely and terminates flush with the front panel side 22a. When seating the second furniture panel 22 on the first furniture panel 2, the collector contacts 26a, 27a come into electrically conductive contact with the busbars 4a, 4b of the first furniture panel 2. The resilient free profile ends of the U-shaped rail profile are spread apart elastically by the collector contacts 26a, 27a, which results in a greater contact pressure.
