Description

The invention relates to the power supply device and, in particular, to prefab constructions of current-conducting channels.

In the international patent application PCT/ASH/95/00675, a flexible cable channel system is described. The cable duct system below is an improvement on this earlier system. A similar cable channel system is described in the international patent application PCT/ASH/O7/00589.

The cable duct systems listed in the documents mentioned above offer superior conductors for conductive duct systems. In particular, the elongated flexible conductors proposed in the PCT documents mentioned above have been shown to be capable of passing higher currents compared to previously known current-conducting channel systems.

However, the conductors described in the above-mentioned international documents are not suitable for high current densities.

As for the above-mentioned international documents, when connecting communication devices with conductors, they often encounter significant electrical resistance.

The task of this invention is to improve the above-mentioned systems of current-conducting channels.

In this invention, for the first time, a current-conducting channel is proposed, containing: an elongated flexible conductor formed by a plurality of transverse ribs placed along the conductor with gaps so that adjacent ribs have a gap between them; and a flexible insulator, which for the most part surrounds the conductor and provides access to it, and holes are provided in the insulator so that air can pass through the conductor between adjacent ribs for the purpose of cooling the conductor.

In addition, the present invention proposes a prefabricated power supply structure, which includes: an elongated base, in which several generally parallel grooves of the same length are provided; an elongated flexible conductor placed in each of the grooves, and each conductor is formed by a plurality of transverse ribs placed along the conductor with gaps so that adjacent ribs have a gap between them; flexible insulator, which for the most part surrounds each conductor and provides access to it; moreover, holes are provided in said housing and insulator so that air can pass through the conductor between adjacent ribs for the purpose of cooling the conductor.

A preferred embodiment of the present invention will now be described by way of example with reference to the accompanying illustrations, wherein:

Fig. 1 - schematic vertical section of the prefab power supply structure;

Fig. 2 is a schematic perspective view of the conductive channel from Fig. 1;

Fig. 6 is a schematic enlarged view of the upper part of the section "B" shown in fig. 5; and

Fig. 7 is a schematic enlarged view of part "A" shown in FIG. 5.

The attached illustrations schematically show a prefab structure of the power supply 10, which can be used, for example, as a plinth near the interior wall of a building. Prefabricated structure 10 includes a base 11, which is designed to be fixed to the supporting wall with the help of fastening means 12. The base 11 includes a longitudinally elongated separating element 13, which has generally rigid walls 14, which connect to the end wall 26, forming and separating in general, three parallel grooves 17, 18 and 19 of the same length. The grooves 17, 18 and 19 are open to a horizontal access channel 20. The prefab structure 10 can be adapted to connect, for example, to an electrical coupling device described in the document

PCT/ASH/O7/00589.

Each groove 17, 18 and 19 houses an elongated flexible conductor 15, each conductor 15 being generally surrounded by a flexible insulator 16. Each insulator 16 generally surrounds a corresponding conductor 15 and provides access to it through the groove 50.

Insulator 16, shown on the left in the assembly, as seen in Fig. 1, has a prong 21 that engages with projections 22 to hold the insulator 16 in a fixed position. The other two insulators are held with the help of protrusions 23.

The separating element 13 in its wall 24 has holes located at a relatively constant interval so that the fastening means 12 can pass through them and reach the cavity 25. From the cavity 25, the fastening means 12 pass through the wall 26. The fastening means 12 is connected to the pressure plate 27 , which adjoins the wall 24. This installation not only attaches the prefabricated structure 10 to the surface of the supporting wall, but also fixes the separating element 13 to the base 11 and holds it.

Integral with the wall 11 is a flexible projection 28 which moves from the position shown to provide access to the conductor 15 above it.

In Fig. 2, it can best be seen that one of the insulators 16 is cut transversely to form holes 29, which at certain intervals open parts of the corresponding elongated flexible conductor 15.

The protrusion 28 creates openings, being in a displaced state, while the wall 24 is provided with openings 30.

Each of the elongate flexible conductors 15 is comprised of a plurality of ribs 31, each rib comprising a generally "O" portion with two branches 32 attached to a curved base 33. The end portions of the branches 32 extend to the curved portions 34, each of which is attached to longitudinal ridge 35. The ridges 35 extend along the conductor 15, being attached to the ribs 31. The ribs 31 are elastic, and therefore when the ridges 35 are disconnected, they are pressed in the direction of each other, as a result of which they hold the pin of the above-mentioned coupling device.

Ribs 31 are separated by gaps 36.

Air can flow through the conductor 15, passing along the conductor 15 and leaving it through the gaps 36 and the holes 29. In order for the air to pass through the conductor 15, the projection 28 is deflected by the pins of the plug or the coupling device, and the air from the space above the conductor 15 exits through holes 30 in the wall 24. Leaving the holes 30, the air ends up in the cavity 37. If necessary, the air can then go out into the space of the room. For this, for example, outlet holes can be provided in the outer casing 38. In this regard, it should be taken into account that a significant part of the heat is released in the place where the conductor 15 is closed with a coupling device or plug, with the help of which the conductor 15 is connected to a household electrical appliance or other object that consumes electricity. The circulation of the air flow is facilitated by the heated air, which rises through the conductors 15 and leaves the assembly structure 10. There are holes 29 along the conductor 15 at regular intervals. The separating element 13 is attached to the end wall 26 with the help of longitudinally elongated protrusions 39, which have teeth 40. Protrusions 39 have the ability to elastically deform, and therefore the teeth 40 occupy a place behind the corresponding teeth 41 of the separator 13. This "quick-action engagement" is best shown in Fig. 7,

Installation of the separator 13 is also facilitated by the engagement of the wall 14 (closest to the wall 26), which is attached to the wall 26.

The separating element 13 is attached to the outer casing 38 with the help of three clips 129, 130 and 131. The clips from 129 to 131 are located so as to take into account the permissible deviations in the design of the outer casing 38. In particular, the clip 131 has an "O-shaped" part 132, inside which the protrusion 133 is placed. These permissible deviations in dimensions are provided, in particular, by the elastic deformation of the connecting part 134, which holds the protrusion 133, and the connecting part 135.
