Description

A cable and rail connector
Technical Field
The invention relates to a cable, specifically to a cable for the production of rail connectors and cable connections, to provide a conductive path for the traction return current in rails and rail connectors.
State of the Art
Currently, a number of cable designs are known, which are used to conduct electric current.
Cables are also known, which are used for the production of rail connectors and cable connections. These cables are made of insulated copper wires. These cables conduct electric current very well, but they have the major disadvantage that they are very often the object of theft. In view of this, these copper cables are being replaced by cables made of galvanised steel. However, those have a number of disadvantages, including, for example, their low electrical conductivity. To ensure the prescribed conductivity of rail connectors and cable connections, at least 3 parallel rail connectors or cable connections must be used. Another major disadvantage is that the rail connectors and cable connections are very rigid and therefore difficult to assemble, and it is very difficult to shape them so that they do not hinder track maintenance.
From the utility model CZ8953U, a multi-strand steel cable is known, which consists of a central strand, around which there are other strands that are wound in layers in one winding direction, and on top of them rests a layer of upper strands that is wound in the opposite direction.
From another document CS2095Q1 , a cable for conducting electrical energy is known, consisting of an aluminium conductive sheath surrounding a supporting steel core formed by a steel cable, which is provided with at least one protective layer for the steel core between the aluminium sheath and the steel core, the protective layer being sheet aluminium.
A cable for rail connectors and cable connectors is described in utility model CZ11085U. This cable consists of several layers. Its internal metal filling consists of at least one layer of steel bundles placed on a non-metallic or metallic core, and on it is placed an electrically conductive sheath, consisting of a single layer of aluminium wire, with the cable being covered with an insulating sheath.
From the utility model SK 2548, the design of a cable is also known, in which the inner part of the bundle is made of copper wire and the outer bundles are made of steel wire. Although this construction prevents theft of the cables from the track while at the same time achieving the necessary electrical conductivity of the cables, the disadvantage of this design is the insufficient mechanical flexibility of the cables, which makes for difficult handling during their assembly in the track.
The main disadvantage of the current technology that the known cables are not mechanically flexible enough, do not have good electrical conductivity, and at the same time are not theft-resistant due to their design.
The goal of the invention is the design of a cable that will satisfy all the above parameters, and that will have good electrical conductivity, will be sufficiently mechanically flexible, and at the same time will be resistant to theft.
Principle of the Invention
The mentioned deficiencies are largely removed and the objectives of the invention are fulfilled by a cable, in particular the cable in rail connectors and cable connections used to ensure a conductive path for the traction return current in the tracks, which consists of individual strands that contain wires intertwined with each other, according to the invention, characterised by that it comprises a core strand, a surface layer of strands and at least one interlayer of strands arranged between the core strand and the surface layer of strands. The advantage is that the more layers used on the prescribed cross-section, the better the flexibility of the cable.
It is to advantage if each of the strands contains at least 15 wires. The advantage is that the more wires used, the smaller their diameters can be, making the resulting cables more flexible.
It is further to advantage that the surface layer comprises strands consisting of steel wires, the steel wires being to greatest advantage galvanised steel wires. The advantage is that the surface layer of the strands, which are made of steel wires, is both resistant to theft in itself, and because of this, it also does not atract theft, like cables made of copper wires only. In an advantageous arrangement, the central strand and the strands of the interlayer consist of copper wires, the total cross-section of which is at least 50 mm2.
Thanks to this, it is possible to achieve such an overall minimum diameter of the cable, which will have optimal conductivity and at the same time have excellent flexibility.
It is also advantageous if the individual wires have a maximum diameter of 0,65 mm, and it is to greatest advantage if the individual wires have a maximum diameter of 0.45 mm. The advantage is that the smaller the diameter of the wires used, the better the flexibility of the cable,
Furthermore, it is also to advantage if the central strand, the strands of the interlayers and the strands have a surface layer of wires arranged in such a way that the direction of their winding is different in the individual mutually adjacent layers. The advantage is that, thanks to this arrangement, the torsion of the cable is reduced, which leads to its better and easier handling.
To an advantage, an insulating layer is arranged on the surface layer of the strands. This layer protects the cable from its degradation due to the influence of the surrounding environment.
The main advantage of the cable according to the invention is that it has less rigidity and is therefore very flexible and so, easy to manipulate. Ail this while meeting the necessary conductivity parameters. It is also to advantage that the cable is resistant to theft thanks to the surface layer of strands being made of steel wires.
Furthermore, the mentioned deficiencies are largely removed and the goals of the invention are met by a rail connector, especially the rail connector containing the cable described above, according to the invention, characterised by that it contains at least one terminal lug, which is connected to the cable by at least one pressed crimping. The advantage is a solid connection, which ensures that the technical requirements for rail connectors are met.
It is to advantage when at least one pressed crimping is arranged on the surface layer of the cable. The advantage is the provision of a conductive connection.
Furthermore, it is advantageous if at least one other pressed crimping is arranged on the insulating layer of the cable, thereby limiting the penetration of corrosive influences. The advantage is the strengthening of the connection of the cable with the terminal lug. Pressed crimpings are, to advantage, provided with an insulating layer. The advantage is the protection of the crimping against the effects of the surrounding environment.
The rail connector, according to the invention, meets the conditions for transferring the traction return current when bridging non-conductive or unreliably conductive pans of the track.
Cable connections, using cables according to the invention, ensure reliable connection of impedance bonds and other elements of track circuits to the rails.
