Abstract

Method of fixing conductors to all the usual supports, adopting a conductor shape comprising a flat part precoated with adhesive and protected by a special film (3) which can be stripped off at the time of fitting. The adhesive part of the conductor may comprise cavities (2) filled with adhesive in order to improve the adhesion to the non-smooth walls. This fixing method may find application in the industrial and building sectors.

Description

The present invention relates to a method for fixing electrical cables and wires on all common supports.

The current methods most often used are collars, hooks, tabs of different shapes, jumpers, staples, etc. in the case where the wires are visible. For example: telephone wires, television wires, HIFI chain wires, low voltage electric wires 110/220 with two or three conductors placed in apparent in the dwellings. There are many other applications where the same problem arises. Indeed, during installation, installers are often faced with the problem of support materials that do not mean using spikes or staples. In addition, the presence of the hooks on a decorated wall is not very aesthetic.

To solve this problem, some installers use the glue gun, but the conductors are not designed for this and it is not very easy to use. The invention incorporates the principle used for the installation of seals. The laying thread has a shape comprising a flat part, this part is pre-glued and protected by a special film which must be removed at the time of installation. To improve the adhesion of the conductor on unread supports, the conductors have small shallow and short cavities (1cm approx.) Arranged at regular intervals on the side of the smooth part. These cavities contain liquid glue trapped in the cavities and protected by the adhesive film. When the film is removed, the contact pressure of the conductor on the support releases small quantities of glue with regular space and the chosen glue polymerizes immediately. Thus the attachment is safer and sufficient on supports such as concrete, stone or plaster.

Other characteristics and advantages of the process according to the invention will become more apparent from the following description of several exemplary embodiments given by way of non-limiting example with reference to the appended drawings in which
Figure 1 is a sectional view of a standard telephone conductor having 5 pairs of insulated conductors.

 Figure 2 is a sectional view of the same type of 5-pair conductors whose external shape (1) has been modified so as to obtain a flat surface on the support side. Small holes (2) can be added on each side to receive a small supply of glue. A thin film (3) protects the pre-glued surface and closes the openings.

 Figures 7 and 8 show the detail of the film and the orifices.

Figure 3 shows the section of a television wire.

FIG. 4 represents the same wire, the outer envelope (1) of which has been modified as the first example.

FIG. 5 represents an electric wire with two conductors.

FIG. 6 represents the same wire, the external envelope of which has been modified to obtain a flat part and a single row of cavities of the same style shown in FIG. 8.

Other forms of conductors are possible (oval, flat, trapezoidal, etc.)
The colors can also vary endlessly and even decoration can be considered to improve the aesthetics and integration on the walls covered with wallpaper.

This method of fixing medium-sized wires and will find application inside dwellings or building installations when the conductors are visible. The same process can be extended to the fields of machine tools, the automobile industry, aviation, railway wagons, etc. wherever there is a need to fix conductors or electrical harnesses.

Claims (3)

1- Method of fixing electrical and conductive wires to all common supports, by pre-gluing the conductor, part of the section of which is flat and protected by a special film which must be removed at the time of installation. 2- fastening method according to claim 1 characterized by the presence of shallow and short cavities arranged at regular intervals on the side of the flat part of the conductor and containing a liquid adhesive which polymerizes as soon as the protection by the film is removed and that the conductor is applied against the wall or the wall. 3- Electrical conductor having an outer envelope which can be of color, or of various shapes, or possibly decorated, a flat part receiving a pre-gluing protected by a thin film.
