Perfected device for the wall-fixing of elongated bodies, in particular radiating coaxial cables

Abstract

A device for the wall-fixing of elongated bodies, in particular radiating coaxial cables, of the type equipped with a spacer provided with a cable clamp (12) equipped with a lid (13) for supporting an elongated body (3) in a suspended position onto a wall (6,14). The spacer of the device of the invention has a structure composed of two arms (15a, 15b), whose end (17a, 17b) facing said wall (6, 14) is provided with a corresponding base (18), whereas the opposite end of said arms (15a, 15b) carries a base (16) for fixing to said cable clamp (12). With respect to the known wall-fixing devices of radiating coaxial cables, that according to the invention offers the advantage of having an improved resistance to flexural and torsional stress, also preventing interferences with the metallic part of the wall-fixing system.

Description

technical field [0001] The present description relates to an improved device for wall fixing elongated bodies, especially radiating coaxial cables. [0002] The field of the invention is that of systems used to support elongated bodies such as eg radiating coaxial cables. Background technique [0003] Devices are known from applications of this type, which fix radiating coaxial cables crimped through specific cable clamps to the wall by means of spacers. Metal screws are then used to make the cable clamp and the spacer integral with each other and also to fix the spacer to the wall with the aid of suitable dowels or similar, the axis of the metal screw being in the position containing the cables. on the same plane as the axis. [0004] In known applications of this type, deficiencies are found, attributable above all to interference with the signal emitted by the radiating cable, caused by the metal body of this radiating cable close to the screw. [0005] A further disad...

AI Technical Summary

Problems solved by technology

[0006] In addition to the disadvantages indicated above, there is the following disadvantage: when the system is mounted on the ceiling, i.e. in a vertical position, the weight of the cables rests in the opening direction of the cover of the cable clamp

This solution has the disadvantage that it offers a very low resistance to deformation during the passage of the train in the tunnel, especially due to the pressure of the air movement on the rod

On the other hand, the bending stresses that are also exerted on the screws are detrimental to the stability of fixing the plate in the hanging position
