Definitions
- the invention relates to a cable of electrical transmission conductors information. It also relates to a method of manufacturing such a cable.
- each pair of conductors The most common solution for shielding each pair of conductors is to arrange a metallic or metallized ribbon in a helix around each of these pairs, the cable being formed by assembling the shielded pairs in the same protective shealth.
- the operation of individual shielding of the pairs is slow and delicate to implement.
- the individual shields of the pairs must be removed to access the conductors, this which makes the connection operation usually carried out on site difficult.
- Document EP 0 915 486 A which belongs to the state of the art referred to in article 54 (3) EPC, describes a cable for the transmission of information comprising a set of pairs conductors, isolated from each other so as to limit the crosstalk between the pairs, comprising two flexible longitudinal ribbons separating the pairs, these ribbons applying around each pair due to twisting of the cable.
- These ribbons are made of aluminum sheets, possibly covered with plastic.
- the invention provides a flexible cable having good insulation properties between conductors, between pairs, or between quartes, and which, in addition, is of an embodiment and particularly simple to use.
- the present invention provides a cable for the transmission of information comprising a set of conductors, or pairs or quads of conductors, isolated from one another so as to limit the crosstalk between the conductors, pairs or quads. , characterized in that it comprises at least two flexible metallized longitudinal ribbons separating the conductors, pairs or quads, these ribbons being applied around each conductor, pair or quarter due to twisting or twisting of the cable, said tapes being folded so that the shielding of each conductor, pair or quarter is ensured by a double thickness of tape.
- longitudinal ribbon is meant a ribbon which is not wound in a helix.
- the cable is more flexible than with a dividing cross, and it is simpler and faster to perform.
- the necessary twist for the ribbons wrapping around each pair may be of low value. She may even be obtained practically naturally by winding or unwinding the cable at the periphery of a coil during manufacture.
- each ribbon is folded according to a longitudinal line, the two sections being on either side of this fold being applied one against the other and being extended each by a end section having the longitudinal edges of the ribbon, these sections of ends being applied against the corresponding end sections of the other ribbon.
- the central sections of the two ribbons and the sections ends of a tape applied against the corresponding end sections of the other ribbon forms four flexible walls, and thus delimit four compartments in which the conductors, pairs or quads are inserted. Due to twisting or a twist of the cable, each of these flexible walls is wound around the conductor, of the pair or the fourth.
- the longitudinal fold line can be central so that the four longitudinal sections of each ribbon have the same length, or it can be offset from a center fold line so that the four sections longitudinal of each ribbon have different widths.
- the invention applies to a cable having any number of conductors, pairs or quads isolated from each other.
- At least one of the two ribbons, or each ribbon can be, in a mode of realization, formed by a composite material comprising an insulating support on which is arranged a metal.
- This composite ribbon is for example "Aluster", that is to say a polyester insulator covered with aluminum.
- the shaping of the ribbons can be carried out simultaneously with the laying of the conductors, pairs or quads in the compartments thus produced, laying taking place, of course, downstream of the shaping.
- the cable has four pairs of wires twisted 10, 12, 14, 16. Each pair is conventionally formed by two wires insulated 18, 20 (for pair 10), each wire comprising a central conductor and a insulating sheath. The two wires 18 and 20 are twisted together.
- Aluster ribbon consists of an aluminum foil applied against a polyester sheet. In the following description, such a ribbon will generally be referred to as composite tape.
- Each ribbon 22, 24 ( Figures 1 and 9) is, during its manufacture, folded so that it has four sections separated by longitudinal folds.
- the ribbon 22 has a fold central 26 on either side of which there are two sections 28 and 30 of widths applied against each other.
- Section 28 is extended by a section 32 to right angle which ends with a longitudinal edge 34.
- the section 30 extends, in contrast, by a second end section 36 ending in the second longitudinal edge 38.
- the ribbon 24 is folded with two central sections 28 1 and 30 1 applied one against the other and two end sections 32 1 and 36 1 . Sections 32 and 32 1 are applied against each other. Likewise, section 36 is applied against section 36 1 . In this way, the two ribbons form, in cross section, a cross with four branches of equal length. The first branch is formed by sections 28 and 30, the second by sections 32 and 32 1 , the third by sections 28 1 and 30 1 and the fourth by sections 36 and 36 1 .
- the four branches mentioned above delimit four compartments, respectively 52, 54, 56 and 58, in each of which is installed a pair twisted, respectively 10, 12, 14 and 16.
- each flexible wall which consists of two central sections of a same ribbon or by two end sections of two different ribbons, wound around a pair and is applied against that pair.
- FIG. 2 shows that the two sections of ribbon 28, 30 are applied and are wound around the twisted pair 14; Likewise, sections 32 and 32 1 are wrapped around pair 12, sections 28 1 and 30 1 are wrapped around pair 10 and sections 36 and 36 1 are wrapped around pair 16.
- the assembly is surrounded by an external shielding (not shown) and insulation.
- the cable does not have to be twisted for the cross sections to ribbons apply against pairs. Another type of twist can be used.
- each wire has a diameter of 0.53 mm, and each wire has an outside diameter (of the insulation) of 1.42 mm, the continuity wire having a 0.45mm diameter, and the ribbons are composite with one layer of aluminum 50 ⁇ m thick and a layer of polyester 12 ⁇ m thick, cable can be used up to frequencies of 600 MHz with limited crosstalk between pairs.
- the aluminum layer of each tape is turned inward, that is to say that the aluminum layers of sections 28 and 30 are applied against each other and, similarly, the aluminum layers of sections 32 and 32 1 and 36 and 36 1 are applied against each other.
- Figures 3 and 4 is identical to that of Figures 1 and 2 to except that the ribbons 22 'and 24', corresponding to the ribbons 22 and 24 of the Figures 1 and 2 are shorter than the latter.
- the cable thus obtained presents the same advantages as that of FIGS. 1 and 2. One obtains in particular also in this case good protection against crosstalk.
- Figures 5 and 6 is identical to that of Figures 1 and 2 to except that ribbons 22 "and 24", corresponding to ribbons 22 and 24 of Figures 1 and 2, are shorter than the latter and asymmetrically folded (they are for this offset from each other during manufacture). Cable as well obtained has the same advantages as that of FIGS. 1 and 2. We obtain especially also in this case good protection against crosstalk.
- the invention is not limited to a pair cable.
- Soft ribbons could be used to shield between single conductors or between quads or other plurality of conductors.
- the installation for manufacturing includes, for bending and forming the ribbons, guide rollers, the periphery has a shape allowing this forming and this folding.
- two guide rollers 70, 72 are provided, a roller 74 enabling the fold to be produced central 26 and a series of successive rollers 76, 78, 80 and 82 making it possible to form gradually sections 28, 30, 32 and 36.
- the roller 76 has at its periphery 84 a concave V shape which forms the ribbon along two equal sections 86 and 88 ( Figure 9).
- the periphery of the roller 78 begins to separate each half-ribbon longitudinal 86, 88 in two parts intended to form the sections, respectively 30, 36 and 28, 32.
- the folding performed by the roller 78 is shown at 90 in FIG. 9.
- the rollers 80 and 82 complete the shaping and folding. Folding output of the roller 80 is shown at 92 in FIG. 9, while the folding obtained thanks to the roller 82 is represented by part 94.
- a die 96 downstream of the roller 96, completes the folding of the ribbon.
- Guiding means 100, 102, 104, 106 of the pairs are also provided. twisted 10, 12 etc. These guide means ensure the positioning of the pairs in compartments 52, 54, 56, 58 ( Figure 1) after the die 96. The twisting of the cable as a whole is made downstream of the die 96.
- Figure 9 shows especially the case where the ribbons are folded symmetrically, but can be directly adapted in the case where, as in Figures 5 and 6, the ribbons are folded asymmetrically.
- the installation of the ribbons does not slow down the manufacturing of the cable because this installation is carried out at the same time as that of the twisted pairs. So the speed of cable manufacturing is higher than that of a cross-partitioned cable extruded, like the cable described in document FR-2 738 947 cited above.
- the invention also relates to a method of manufacturing a cable which is characterized in that the two ribbons 22, 24 are folded and assembled in such a way that they form a cross with four branches delimiting four quadrants 52, 54, 56, 58, in that after this forming and this assembly we install in each quadrant, a conductor, pair or quarter, and then apply a twist to the assembly, for example a twist.
