Description

Pattern description The subject of the utility model is a hybrid teleinformatic cable for data transmission, enabling, if necessary, its ongoing tracking - routes and easy tracking. identification its ends function as Connectors, intended for placing it both in installations inside buildings with high density of cable routes, as well as for internal horizontal and vertical installations in teleinformation networks.

ICT cables are created by a route through which a large number of digital information, using for this purpose many twisted pairs? insulated from each other, the cables being installed? most often in bundles laid directly in vertical and horizontal ladders or cable trays.

Previously known cables, ICT and telecommunications for data transmission, including applications inside object objects contain? cross separators made of plastic, usually polyethylene (PE) or polypropylene (PP), and along the length of the between each two arms of these separators with most often rectangular cross-sections perpendicular to each other, one pair of wires is placed. of a copper wire shielded with insulation polyethylene and twisted together. So placed between four arms of the same length cross separator four pairs of insulated wires? copper transmitting medium are wrapped together foil? shielding, creating round ring their shield ?, under which? next to one of four pairs of these? a grounding wire is placed and all these elements are the outer jacket adhering to this casing is made of a thermoplastic, usually chlorine-free and low-fuming halogen-free (LSOH) type material.

In other known ICT cables, their cross separators have four arms with T-profile in cross section or with triangular profile.

They are known? also teleinformatic cables for data transmission, including cross separators made of polyethylene (PE), and along the length and between each two arms of these separators perpendicular to each other, there are as? four pairs? made of copper wire with insulation polyethylene (PE) twisted in pairs together? and one ground wire. These four pairs of conductors with their separators and the grounding wire are wrapped around foil? type of PET coated? aluminum and outer jacket made of thermoplastic PVC. The ends of these cables are led out? most often in switchgear cabinets, panels, shelves or sockets, and the identification of individual cables in a cable harness in the process of completing their installation poses many difficulties. This causes the length of the the process of installing these cables and the possibility of making a mistake in their connections, which in turn makes their exploitation difficult? and removal of failures. The ends of these cables require? their permanent marking, and the lack of an identification label for a given cable makes it necessary to Retrace the track (route) and find the other end of the correct cable.

On the other hand, the cable known from US5952615 with separately shielded twisted pairs uses a central bar filling surrounded by a shield and a general shield to completely separate the twisted pair. each? twisted? par?. Such a configuration usually requires the shielding members to be grounded. Moreover, one embodiment of the invention proposes two metal bands inside the ribs of the central cross-shaped bar filler. This combination of two metal tapes is not desirable because it enables electromagnetic penetration between the point of connection of these two walls, and moreover, the close location of the screen has a detrimental effect on the stability of the electrical parameters such as impedance and attenuation including polarity reflections.

The data cable known from US2014014394A has a monolithic or shielded foil. a star-shaped separator, made up of four identical arms with a profile of isosceles triangles, symmetrically situated at an obtuse angle to each other, protruding from the central part that strengthens it, equipped with a It is a toughness plate, situated on its axis of symmetry and made of plastic, fiberglass (FGE) or metal. Between each two adjacent triangular arms there are two wires twisted together, with the whole is wrapped in tape foil, for which the metal grounding wire is spirally wound, and the entire the shield is an outer jacket made of polyvinyl chloride.

From the patent description US2009120664 there is known a cable containing a separator made of a sleeve core and four identical arms cut from it, having rectangular rounded profiles in cross-section at their upper ends forming one monolith. so that between them there are four identical longitudinal channels in which there are two pairs of spirally twisted insulated power cables each. the axial opening of the sleeve core is intended for various uses, including the receiving of a stiffening bar element therein. In addition, all separator arms of this cable, made of non-conductive material, are shielded. Three cloaks forming a cable with many twisted pairs of insulated wires.

From JP2005166317A, it appears that a fiber optic cable has four pairs of helically twisted current insulated conductors and is also placed between two pairs of these conductors. an insulated fiber optic cable that adjacent to them with a screen shielded with this outer cloak. Inconvenience? of this cable is that during the application of both the shield and in the process of installing this cable, there is a possibility to broken fiber for easy tracking (optical fiber).

He is also known? from the patent description of the Polish patent application P.416373 hybrid teleinformation cable for data transmission consisting of with a star-shaped, five-blade separator made of polyethylene or polypropylene, placed between and along the with each two arms of this separator pairs of single-module wires? copper with insulation polyethylene, twisted in pairs of wires and from the shielding separator with several pairs of? of copper polyester shielding foil with a shield underneath it. with a copper grounding wire and an external jacket made of thermoplastic material adjacent to this shield, characterized by the fact that in the axis of symmetry of this separator, whose cross-section arms are the shape of an isosceles trapezoid and along its entire length is embedded an information carrier for easy tracking of the transmission path made of single-mode or multi-mode optical fibers, made of polymethyl methacrylate or quartz fiber Fiber optic having a diameter of 0.15-0.80mm. Moreover, between one par? on the arms of this separator there is an optical module transmission arms, and between the remaining four pairs of these arms there are couples? copper with insulation polymer.

Inconvenience? of the known constructions of hybrid teleinformatic cables using five-arm separators is their incomplete axial symmetry, which may make it difficult to achieving the required transmission parameters of a copper module for categories 5e, 6 and 6a or higher. In addition, the use of only a single optical fiber module is a limitation to the creation of a cheaper, separate, dual path optical fiber transmission.

The purpose of the utility model is to eliminate the above-mentioned disadvantages of previously known hybrid teleinformatic cables, by developing a new cable design that meets the requirements of cable type, bandwidth and speed for CAT5 (class D), CAT5e categories. (class DA) and CAT6 (class E), which will allow both full, fast and? easy? identification of the cable along its entire length, at both ends and will allow for double-track transmission? optical.

The essence of the hybrid teleinformatic cable for data transmission according to the utility model is that the cable has six lines. arms forming a monolithic separator, two pairs of these arms facing each other form a profile similar to the letter "X", and the two arms are located? in the axis of its symmetry, horizontally and opposite to each other, so that an acute angle is formed between the inner surfaces of both arms with the "X" profile, which is smaller than the acute angle formed between the inner surfaces of the next four arms, between which they are placed two twisted together Copper conductors with their insulation, while between the two pairs of arms with an "X" profile are placed? Fiber optic single-mode or multimode optical paths, and above them there are threads for tearing the screening foil shielding this separator together with technical means placed between its arms.
