Examples of carrying out the invention

The accompanying drawings schematically depict a power supply unit 10 that can be used, for example, as a sash for an interior wall of a building. The unit 10 includes a base 11 that is intended to be secured to a load-bearing wall by clamps 12. The base 11 includes a longitudinally extending dividing element 13, providing typically stable walls that interact with the front wall 26 to define and divide three parallel equally extending ones. slots 17, 18 and 19. Slots 17, 18 and 19 are open to a horizontal passage 20. Block 10, for example, should be adapted to interact with the electrical adapter described in PCT / SU / 1997/000589.

In each slot 17, 18 and 19 there is an elongated flexible conductor 15, each conductor 15 being generally enclosed by a flexible insulator 16. Each insulator 16 generally encloses the associated conductor 15 and provides access to it through a slot 50. The insulator 16 shown on the left side of the block of Figure 1, includes a pin 21 that engages flanges 22 to hold the insulator 16 in place. The other two insulators are clamped through flanges 23.

The dividing element 13 is arranged at relatively regular intervals with an opening in the wall portion 24 so as to allow the bracket 12 to pass through it to enter the cavity 25. From the cavity 25, the bracket 12 passes through the wall 26. The bracket 12 must engage a pressure plate 27 that rests on the wall portion 24. Such a construction not only holds the block 10 to the surface of the load-bearing wall, but also retains the dividing element 13 attached to the base 11.

As an integral part of the wall lie a flexible flange 28 that is displaced from the illustrated position to provide access to the conductor 15 located above.

As can best be seen from Figure 2, one of the insulators 16 is cut transversely to obtain openings 29 that reveal spaced portions of the associated elongated flexible conductor 15.

The flange 28 provides openings when displaced, while the wall portion 24 is provided with openings 30.

Each of the elongated flexible conductors 15 consists of a plurality of ribs 31, each rib consisting of a "U-shaped" portion providing two arms 32 connected through an arched base 33. The ends of the arms 32 extend to the arched portions 34, each of which is attached to a longitudinally extending flange 35. The flanges 35 increase the length of the conductor 15 so that they connect to the ribs 31. The ribs 31 are elastic so that when the flanges 35 are separated, they are pushed together to engage the adapter pin.

The ribs 31 are separated by gaps 36.

Air can flow through conductor 15 by passing longitudinally through conductor 15, as well as exiting conductor 15 through gaps 36 and openings 29. To allow air to pass through conductor 15, the flange 28 deviates from the pins of a plug or adapter , as the air exits above the conductor 15 through the openings 30 in the wall portion 24. The air exiting the openings 30 enters the cavity 37. If necessary, the air can then be discharged to the enclosure. For example, the outer cover 38 may be provided with vents. In this respect, it should be borne in mind that a considerable part of the heat is generated at the point where the wires 15 are gripped by an adapter or plug connecting the wires 15 to an appliance or other electricity consumer. The air flow is facilitated by the air, which is heated and passed through the wires 15 and exits the block 10.

The openings 29 are arranged at regular intervals along the conductor 15.

The separation element 13 is secured to the front wall 26 by longitudinally extending flanges 39 having teeth 40. The flanges 39 are susceptible to elastic deformation so that the teeth 40 are rearwardly engaged and engage the teeth 41 of the separation element 13. This is a "fast acting" is best illustrated in Figure 7. The positioning of the dividing element 13 is also facilitated by gripping the wall 14 (closest to the wall 26) gripping the walls 26.

The dividing element 13 is secured to it by an outer cover 38 through three connecting brackets 129,150 and 151. The connecting brackets 129 to 151 are arranged to allow variations in tolerance in the structure of the outer cover 38. In particular, the connecting bracket 131 includes " U-shaped portion 152, which houses projecting portion 153. The elastic deformation of the supporting stem 154 of the projecting portion 153 and the stem 155, in particular, provide this dimension tolerance.
