FR2496350A1 - Electrical leads mounted between thin flexible tapes - for connecting electronic appts. at any point along its length - Google Patents

Abstract

Electrical lead comprises two layers of thin flexible insulating tape laminated by longitudinal welds between which are passages to accommodate conductive strips. The lead may be stuck or fastened to wall surfaces so that electronic or electrical appliances amy be connected at any point to insertion of suitable conductive probes through the outer tape. Pref. both conductors and probes have a flat profile and the covering tapes are of flexible PVC or other material sufficiently elastic to maintain the probe in contact with the conductor or to close up the holes left if probes are subsequently withdrawn. The probes may be concealed by an insulating cover or terminal box. Opt. the tape is metallised on its external face to dissipate static charges. The lead may be concealed beneath wallpaper, with a superficial rib to help locate the lead when required.

Description

 The present invention relates to a sheath of electrical conductors allowing instantaneous connection over its entire length of all electrical or electronic devices. This sheath placed on a partition may or may not be made invisible by wallpaper or tapestry.

The following explanations will better understand their purpose:
Between two sheets of PVC or other suitable material, one or more conductive elements are sandwiched; the two sheets are welded or glued together, but only between the conductors over the entire length of the strip, so as to leave -more or less free-conductors in their corridor.

 In order to suppress the strip thus obtained, the external fax machine can be metallized with two sheets of PVC or other material.

The two strips of PVC are, optionally of different width, so that the edges of the strip once formed, are not thicker than one of the two strips and makes it less visible.

This strip may or may not have a layer of glue on the back so that it only has to be applied as a simple ordinary self-adhesive strip. It may or may not be protected by a protective sheet of the glue to be removed when laying any support, it will be, this strip, extremely thin and of a conventional width, as desired, so that when you stick it on a wall, for example, you can line it with above and make it completely invisible. It can be located through paper or tapestry or other, thanks to a slight central boss allowing in the case where the strip has, for example, four conductors, to locate, very easily, the two tracks of two conductors, following this boss with the connection pin, and this, on either side of this boss (I5) .0n can double the strip with a layer of background paper or other protective layer or any other covering of trim or profile, in case it remains visible.

 To establish contact at any point on the strip, you just have to drill at an angle and parallel to the conductors using the ad-hoc pin, for example, the first layer of PVC and push it in parallel to the conductors in the corridor formed by the back of the first layer of PVC and the upper face of the conductor, in the same way that a plug is inserted into a socket. in two conductors, the boss (I5) will be made between them and the connection will be made by placing the pin, astride the longitudinal boss.

 Depending on its use, this strip can be connected in the same way on its two faces, in case, it remains floating or applied on a support allowing it to be pierced with the spindle.

 It can also be made on any support, in any structure, sketch (4-5-6-) by way of non-limiting example or any profile.

 This description is mentioned to make the principle of the possible structure of the invention understandable, it may well be carried out in a single structure, in any profile, as long as the form (7) is left open. pass the covering covering the free conductor (s), and thus establish the connection along these by means of the pin.

 It can also be made on any support, in any structure. The connection pin is formed of blades fixed on a conventional plug body, these blades of a suitable width and length and thin, are sharpened to their end so as to be able to pierce with the aid of these, the covering of the conductive elements of the strip and to be able to insert it into the corridor formed by these, with a slight tightening to obtain good contact while along these blades. The end of the travel of these blades is insulated over an appropriate length so that there is no short circuit between the anti-interference shield and the conductors themselves. This insulation also serves as a plug for the connection and thus makes it airtight.

 As the contact is established on the whole non-insulated surface of the blades, under the shielding, the latter is completely protected, the very elasticity of the material used PVC or other, ensures permanent tightening necessary for the correct connection, in order to obtain a clean connection, an appropriate layer of metal is provided under the slats to prevent corrosion.

 When this plug is disconnected from the connection, there remain on the strip only wounds made at an angle (5) in the cut groove which closes by the elasticity of the material and leaves no metallic surface open to any interference, or other disadvantages, The blade support structure provides on its different sides, different kinds of contact points that can receive any existing commercial plug.

This structure is also designed for connection by instant clipping when it is closed on a
wire side by side in the spindle housing without the K stripping. This structure also provides holes for possible fixing. This description is not limiting, the blades can also be mounted on a simplified support, on a profile responding to a clipping on an ad-hoc profile of the ban, or simply welded or fixed in any other way, either on any wire or device, this strip acting as an extension.

 The drawings shown and described are given here only for schematic, non-limiting indication and are subject to numerous, variant embodiments and applications, as a new industrial product.

In (6) the blades, In (7) the spindle or case.

 FIG - 2 - shows, in section the unfolded pin (7) showing in (9) the points which will contact the wires resting with their insulator in the cavities (IO) or the contact will then be established during folding on the second part of the housing (7).

 FIGS. 4-5-6 are variant profiles of a connection plug.

FIG - 7 - represents, seen in section and in perspective, the position of the sheath placed along the interior partitions (I2) of an apartment from where contact can be made at any location
Of course this sheath can be covered according to the choice of wallpaper or tapestry, making it invisible or not.

 It can be designed for low or medium voltage.

 Of course, the invention is not limited to the embodiment shown and described, and to the drawings appended by way of example, but it can vary in shape, in material of dimensions, without the principle of the invention being altered, the aim being to remain within the framework of the new idea which is the subject of this present patent.
