  • the wire 28 is passed in the same way into a central bore 32 of the block 30 and is folded back as shown in 28a around the base 30a of said block.
  • a collar 33 of an electrically insulating and preferably resilient material is designed to clamp the folded portion 27a of the wire 27 against the inner wall of the widened portion 20. of the sleeve 14.

  • the sleeve 14 has a fixed length while the portion 12 is of variable length, depending on the plugs, in order to reach and pass through any of the sheets 2, while the portion 15 of the sleeve 14 only reaches the first sheet 2, which is illustrated in FIG. 5, 5a.
  • the latter is pushed through one of the panels such as A, B, until coming to a stop withthe skin 3 formed on the surface of each panel.

  • the perforation forms collars 34 on each side of the bored passage into each sheet 2.
  • FIGS. 5 and 5a show that the electrical contact can be still perfected by placing a spring, for example a resilient washer 35, beneath the widened portion 20, said washer tending to lift the plug after the penetration of the same and its rotation by 90, thus substantially lozange shaped portions 13, 15 are thereby better applied against the collars 34.

Consequently, the sleeves 14 of all the plugs D are always at the same potential as said plugs engaged into one or the other side of each panel.
  • said sheets are, for example, connected to separate conductors 38, 38a 38 each of them being connected to a voltage variator 39, 39a 3911 supplied through special switches 40, 40a 4011, which are themselves connected to a general voltage variator 41 which can be supplied from the other terminal 370 of the supply source by a switch 42 enabling, if required. to connect said terminal 37a of the supply source when being in the position represented to the same conductor 38, 38a 3811 but through different programmation device 43.
  • the plugs D By placing the plugs D according to various arrangements and by selecting plugs D intercepting a particular one of the sheets 2, very various illuminations can be realized since the corresponding bulbs can be lighted in function of various parameters depending on a handcontrol of switches 40 and voltage variators 39, 39a .39n and 41 or, yet, controlled by the programmation device 43 which can, for example, be constituted by a device sensitive to a sound-program.
  • FIG. 7 shows a slight variant in the realization of the plugs; in such a variant the portion 11 covered with the insulating casing 16 is made so to have a diameter smaller than that of the base 13a of the lozange shaped portion 13.
  • the casing 16 has no friction against the material constituting the plates 1 and sheets 2, whereby the pressure to be exerted on the plug to make the same to penetrate remains substantially the same whatever the length of said plug.
  • Said limitation of the friction also provides the spring 35, when in use, to have a more efficient action to maintain the portions 13 and 15 against the collars 34 of the conducting sheets 1, since then the friction between the casing 16 and the material of the plates'l is material.
  • the portion 13 is topped by a second portion 13 being also substantially lozange shaped, and it is the same for the portion 15 which is also topped by a portion 15 of a similar shape.
  • Said arrangement is especially advantageous when two plugs are placed in a panel at a very short distance of each other.
  • the first engaged plug can cause a warping of the conducting sheet 1 which is passed through by said plug, and said warping can be prejudicial to a good electrical contact which should exist between said sheet itself and the second plug placed in the immediate vicinity of the first one.
