- CONNECTION LINE IN PARTICULAR WAGON TRANSITION LINE, AND METHOD FOR PRODUCING SUCH A CONNECTION LINE
- the present invention relates to the field of cable technology. It relates to a connecting line according to the preamble of claim 1 and a method for producing such a connecting line.
- the broadband signal transmission elements in the form of coaxial cables which are integrated into the wagon transition lines and are stranded with the other power supply and signal cables are also used for the wagon transfer lines of modern high-speed trains. It has now been found in practice that especially the coaxial cables can be locally deformed or otherwise changed by the extreme mechanical loads which act on the car transfer lines freely suspended between the car bodies. This is noticeable in the deterioration of the signal transmission quality which increases over time and which can impair the safe and proper operation of the high-speed train. Other sensitive fasteners can also be affected by the negative effects of stresses that occur during operation.
- the essence of the invention is to provide, during the production of the connecting line, a dimensionally stable channel running with the stranding, in which one of the cables stranded with one another is or is drawn in with radial play.
- a dimensionally stable channel running with the stranding in which one of the cables stranded with one another is or is drawn in with radial play.
- an empty tube or an empty channel is first arranged or provided in the cable, into which the connecting element to be protected is then pulled. This eliminates the need to first have to manufacture a special protected cable (with protective tube). It is also ensured that the cable drawn into the duct can be easily removed and replaced if necessary.
- the channel is empty, a coaxial cable or a bundle of optical fibers or other conductors can be pulled in.
- the cable drawn into the at least one channel is preferably a coaxial cable.
- the at least one channel is formed by the interior of a protective tube stranded with the other cables.
- the shape, dimensions and material of the protective tube can easily be optimized with regard to protection (dimensional stability etc.) and processability (strandability).
- the protective tube consists of a material that is easy to slide, preferably a plastic. This ensures that the cable can be easily and easily pulled into the empty protective tube even with a cable length of several meters.
- the protective tube consists in particular of a polyamide alloy and has a wall thickness of at least 0.8 mm.
- the protective tube preferably has a circular cross section and the inner diameter of the protective tube is at least 0.5 mm and not more than 2 mm larger than the outer diameter of the cable drawn into the protective tube. It is also advantageous if the lay length of the stranding is between 9 times and 12 times the bundle diameter of the stranded cables. With such a configuration, the cable in the protective tube has the necessary freedom of movement to be safely protected against the external mechanical influences.
- the at least one channel can also be formed by a cavity in a one-piece cable body.
- a preferred embodiment of the method according to the invention is characterized in that in the first step at least one protective tube is stranded with further protective tubes and / or cables, and in the second step the cable is drawn into the at least one protective tube.
- a one-piece cable body with at least one channel extending helically in the longitudinal direction can be produced and in the second step the cable can be drawn into the at least one channel.
- FIG. 1 in a highly simplified perspective view
- Section of a one-piece cable body with two empty channels "stranded together" for pulling in cables according to a first preferred exemplary embodiment of the invention
- FIG. 2 in a representation comparable to Fig. 1 shows a section of a
- Connection line with two empty protective tubes stranded therein for pulling in cables according to a second preferred embodiment of the invention
- FIG. 3 shows the cable body from FIG. 1 with a coaxial cable drawn into the one channel; 4 shows the connecting line from FIG. 2 with a coaxial cable drawn into the protective tube; and
- Fig. 5 shows the cross section through an exemplary carriage transfer line of a high-speed train with two coaxial cables protected according to the invention.
- the present invention provides for mechanically decoupling sensitive elements of the connecting line in the line.
- a protective tube built into the connecting line made of a material that is easy to slide (preferably plastic).
- the elements to be protected are then drawn into the protective tube. Any forces on these elements can be reduced immediately.
- the number of protected resp. "Normal" built-in elements are basically arbitrary. The elements are processed together in a bundle which has a stranding; ie the elements are "twisted".
- an extruded chamber system is also conceivable, in which the individual chambers or channels (round, honeycomb-shaped, etc.) are arranged spirally and can be equipped with individual elements or stranded elements.
- 1 shows a simplified exemplary embodiment of such an extruded chamber system.
- the starting point is an extruded (cylindrical) cable body 10, in which two channels 11, 12 with a circular cross section are arranged in a spiral (“stranded”) arrangement.
- the channels 11, 12 can also have other (rectangular, square, trapezoidal) instead of the circular ones , circular sector-shaped etc.) Likewise, more than two channels or only one channel can be provided.
- the cable body 10, of which only a short section is shown in FIG. 1, is first extruded in an economically and technically sensible length and then cut to length as is necessary for the finished connecting line or wagon transfer line.
- the “stranding” of the channels 11, 12 ensures that there is sufficient cable length in the finished line so that the cables drawn into the channels 11, 12 are axial Strains of the line are not mechanically stressed.
- the inside diameter of the channels 11, 12 is selected such that the drawn-in cables are sufficiently spaced on all sides from the inside wall of the channels 11, 12 and are thus mechanically decoupled from the cable body 10 without taking up too much additional space.
- the difference in diameter between the inside diameter of the channels 11, 12 and the outside diameter of the drawn-in cables should be in the range between 0.5 mm and 2 mm.
- plastics and plastic mixtures (“blends”) come into question as material for the cable body 10, which are easy to process on the one hand, and on the other hand are flexible and dimensionally stable, and have good sliding properties on the surface, so that the cable can be used even with a length of several meters the line can be drawn into the channels 11, 12 without difficulty.
- a coaxial cable 19 (which is sensitive to mechanical loads) is drawn in, which essentially consists of a central inner conductor 22 and a concentric outer conductor (shielding) 21 spaced therefrom there, the space between the two conductors being filled with a dielectric 23.
- the coaxial cable 19 is almost completely mechanically decoupled from the cable body 10 when the cable body 10 is stretched, bent, twisted, impact-like and the like. Local deformations of the concentric conductor arrangement 21, 22, 23 and their degrading influence on the line properties are thus reliably avoided even under difficult conditions.
- the coaxial cable 19 instead of the coaxial cable 19, other mechanically sensitive cables, conductors or lines, such as optical fibers, can also be drawn into the channels 11, 12 and thereby protected.
- FIGS. 2 and 4 show, in a greatly simplified representation, the section of a connecting line in which two protective tubes 15, 16, which are “stranded” with one another, are arranged in an inner space 14 surrounded by a casing 13.
- the inner spaces 17, 18 of the protective tubes 15, 16 form 4 and, analogously to FIG. 3, mechanically sensitive elements such as a coaxial line 19 can be drawn in to complete the connecting line 24.
- the hollow cylindrical protective tubes 15, 16 are made of a highly lubricious plastic mixture, in particular a thermoplastic PA /
- the protective tubes 15, 16 have a wall thickness of at least 0.8 mm, and their inner diameter is chosen such that the diameter free space of the coaxial cable 19 in the protective tube 16, ie the difference between the inner diameter of the protective tube 16 and the outer diameter of the coaxial cable 19 is between 0.5 mm and 2 mm.
- the comparatively stiff protective tube e 15, 16 acquire a certain flexibility when stranded without losing their protective mechanical properties.
- FIGS. 2 and 4 do not show further conventional individual or pre-stranded cables which are stranded with the protective tubes 15, 16 and thus form a bundle of cables with and without a protective tube (see also FIG. 5).
- the lay length, ie the twist pitch per revolution, is preferably in a range between 9 times and 12 times the bundle diameter of the cable bundle.
- FIG. 5 The cross section through a hybrid car transition cable for a high-speed train, as is used in practice, is shown in FIG. 5.
- 5 is surrounded on the outside by a hollow cylindrical protective jacket 32 made of a resistant TPE material.
- the outside diameter of the exemplary cable is approx. 30 mm.
- An electrically conductive EMC shield 26 is arranged on the inside of the protective jacket 32. To the inside, the shield 26 is covered with a mechanically reinforcing intermediate layer 28.
- the connecting line 30 six conventional, multi-core cables 25, 31, 33, 34, 35, 38 are stranded with two protective tubes 36.
- a coaxial cable 37 is drawn into the protective tubes 36 with radial play. The space between the stranded cables is partially filled with inserts 29 in the form of tear-resistant yarns or the like.
- the cables 31, 34 and 38 are constructed in the same way. They each have 4 wires or conductors and are used as bus lines for the train.
- the cable 25 is a two-wire bus line.
- the two coaxial cables 37 are conventional 75 ⁇ cables with a copper strand as inner conductor, a foamed dielectric and a shield made of copper braid.
- the coaxial cables 37 have an outer diameter of 3.8 mm in this example.
- the inner diameter of the protective tubes 36 is, as can be clearly seen in FIG. 5, considerably larger.
- a connecting line according to the invention is distinguished from conventional solutions, in which all the cables of the line are firmly twisted together, by a higher functional reliability and an increased service life. It is particularly flexible and has a high level of fatigue strength. It is therefore particularly suitable as a flexible connecting cable in the carriage crossings of high-speed trains.
