Abstract

A hybrid pigtail for mobile communications whose novelty consists in combining in a single unit (1) different types of conductors divided into two groups: electric cables or wires (2) and optical cables (3), both types being arranged inside a suitable metallic protection (4) of the type of an interlocking, smooth or corrugated tube provided with an insulating coating (5) and forming a hybrid unit, the ends of which optionally include usual electric or optical connectors for interconnecting various mobile telecommunications appliances.

Description

HYBRID WIRE FOR MOBILE TELECOMMUNICATIONS. Field of the Invention.

More particularly, the present invention relates to a new cabling solution or optimization, combining in a single unit different types of conductors, divided into two groups: electric cables or wires and optical cables, both arranged inside a metal shield type. corrugated, interlocked or plain pipe with any insulating coating, such as polymer, forming a hybrid unit, advantageously used in mobile telecommunications (cellular system sites) in the electrical / optical interconnection between different equipment such as, for example, BTS 3G units and the active antenna unit (RRH, RRU and others).

State of the art.

As is well known, in mobile telephony, currently the interconnection of the above equipment and the like are usually carried out by individual or separate cabling, ie the optical cable part is separated from the electric cable part. This condition not only requires more labor, but also has other implications, mainly facilitating possible vandalism and, in the end, adding the drawbacks, it is concluded that the final cost increases significantly.

Objectives of the Invention.

A hybrid mobile telecommunications harness composed of electrical cables and fiber optics protected by a metal shield (external conductor) and covered with a polymeric coating, including the following characteristics:

(a) Electrical cables may consist of copper, aluminum, copper aluminum, copper steel, silver, gold, and their composite alloys;

(b) Fiber-optic cables shall consist of single-mode or multimode-type optical fibers and their technological derivations, sheathed in polymeric material or in polymeric tubes with or without jelly, and such fiber-optic assemblies shall be assembled together with aramid yarn. or fiberglass yarns and are externally coated (sheathed) with polymeric material;

c) the harness is normally composed of electrical cables and optical fibers in quantities suitable for its application;

(d) A metal shield (external conductor) shall be placed over the electrical / optical assembly, such as, for example, a corrugated, interlocked or plain tube made of copper, aluminum, silver, gold, steel and its alloys; and

e) over the outer metal shield (outer conductor) an insulating layer is preferably applied in the form of a polymeric coating.

Description of the drawings.

For a better understanding of the present invention, a detailed description is hereinafter made, with reference to the accompanying drawing, whose figure 1 represents a schematic and exemplary view of the invention. invention, showing a whip according to the invention. Detailed description of the invention.

The present invention, HYBRID WIRE FOR MOBILE TELECOMMUNICATIONS, is characterized in that it combines in a single unit (1) different types of conductors, divided into two groups: electric cables or wires (2) and optical cables (3), both arranged inside a suitable metal shield (4) corrugated, interlocked or plain pipe with any insulating coating (5), such as polymeric, forming a hybrid unit, the ends of which include or not the usual electrical / optical interconnect connectors between different equipment of mobile telecommunications.

The electrical cable assembly (2) is of the type formed with an insulating outer sheath and a metal conductor of suitable conductivity such as copper, aluminum, copper aluminum, copper steel, silver, gold, and their composite alloys.

The fiber optic cable assembly (3) is of a type consisting of single-mode or multimode optical fibers and their technological derivations, encased in polymeric material or in polymeric tubes, with or without jelly, and also these optical fiber assemblies are assembled together with aramid yarns or fiberglass yarns and are externally coated with polymeric material.

The size of the set is variable and consistent with each project, ie the harness is usually composed of electrical cables and fiber optics in quantities suitable for their application. The metal shield (5), which is an external conductor, is preferably a substantially flexible tube, such as, for example, a corrugated, interlocked or smooth tube of copper, aluminum, silver, gold, steel and their alloys.

The insulating layer (5) is preferably a polymeric coating.

It will be understood that certain characteristics and combinations of the

Electrical cables or wires (2) and optical cables (3) may vary considerably while maintaining the same functional concept for the assembly, therefore, it is noted that the construction now described in detail by way of example is clearly subject to constructive variations. However, always within the scope of the inventive concept of a hybrid whip now disclosed, and as many modifications may be made to the detailed configuration in accordance with the descriptive requirements of the law, it is understood that the present details should be interpreted as illustrative. and not limiting.
