Definitions

  • the invention is initially concerned with the structural design of a symmetrical communication cable, such as is used for switching purposes in telephone exchanges and its construction of a possible assembly of the cable ends, i. H. an automatic connector assembly, also takes into account with a method and a device for producing such a cable.
  • the individual stranding elements such as pairs, three or four are stranded in layers or bundles to form the core.
  • bundling communication cables in bundles which offers advantages with regard to the assembly of sets and with regard to switching work, five star quads or five to ten wire pairs, for example, become one basic bundle and then several such basic bundle stranded into a main bundle.
  • Such a main bundle or several such main bundles form the cable core (DE-GM 66 07 289).
  • each core group (basic bundle) are arranged next to one another on a band-shaped carrier and the carrier is formed with the cores to a tubular structure which represents the basic bundle (DE-OS 20 20 384, DE-OS 20 21 875 ).
  • a switching cable consisting of a so-called ribbon cable is known, in which the ribbon cable is alternately folded right / left and surrounded with a sheath to improve its flexibility (US Pat. No. 20 04 612).
  • Ribbon cables in which a number of individual insulated conductors are attached via their insulation to a common carrier body, can moreover be produced by first arranging the wires around a fixed mandrel and then facing the wires away from the mandrel overmolded ten sides with a common plastic sheath and that finally the plastic sheath is cut parallel to these after removal of the mandrel between two cores and bent up to the carrier body (DE-AS 15 15 813).
  • the cable core surrounded by a cable sheath essentially consists of one or more core groups, which in turn consist of several stranded core pairs, the core pairs of each core group being connected to one another transversely to the longitudinal direction of the core by means of flexible holding elements arranged at regular intervals and form a flat cable
  • the object of the invention is to improve the structural design of such a cable with regard to its flexibility, electrical properties (coupling values) and rational production, and a method which is particularly suitable for producing such a cable and one for carrying out the method to create suitable device.
  • the invention provides that the flexible holding elements consist of threads or tapes glued or welded on one side to the wire pairs or of a holding helix spun onto the wire pairs arranged next to one another and glued or welded to the wire pairs, and that the wire pairs of each wire group are formed into a bundle and stranded or twisted together.
  • the individual core groups can be manufactured continuously, Through the cross-connection of the cores of each core group by means of threads or tapes glued or welded to the core insulation point by point, a very good flexibility of each core group is achieved both in the longitudinal and in the transverse direction, and the stranding or twisting of the core pairs formed to form a bundle results in relatively low results Coupling values between the wire pairs of neighboring wire groups.
  • a method is particularly suitable for producing the new communication cable, in which a flat cable is temporarily formed from several wire pairs and in which, in a further development of the invention, the wire pairs are first guided along the surface lines of a cylinder and are temporarily fixed in this assignment by means of a holding spiral, the Holding coil is glued or welded to the surface of the wire pairs, and in which the holding coil is subsequently cut in the same operation between two adjacent pairs of wire lines assigned to each other, and that by means of the separated hold helically cross-connected wire pairs are formed into a bundle while leaving the surface lines of the cylinder and are twisted or twisted together to form the wire group.
  • the holding elements with which the individual wire pairs of a wire group are connected to one another transversely to the longitudinal direction of the wire, are applied in a continuous operation.
  • a device is particularly suitable for carrying out this manufacturing method provided in a further development of the invention, in which a cylindrical mandrel running in the axis of the perforated disk is arranged behind a fixedly arranged perforated disk for guiding the wire pairs, to which a disk-shaped guide piece for assigning the Wire pairs are assigned to the surface lines of the mandrel, a spinner for attaching the holding helix, a device for gluing or welding the holding helix to the wire pairs and a device for cutting open the bonded or welded holding helix, and in the connection to the mandrel, a device for stranding the wire pairs are arranged to the wire group.
  • Such an arrangement can be adapted to different numbers of wire pairs by different selection of the mandrel diameter. Furthermore, the distance between the pairs of a core group can be varied as the dimension of the mandrel changes.
  • Fig. 1 shows a communication cable
  • the cable core consists of the main bundle 1, the one with a longitudinally shaped to the tube shaped metal strip 2 and a plastic jacket 3 existing cable jacket is surrounded.
  • the main bundle consists of the five bundles 4 stranded together and each bundle 4 consists of a core group designed according to the invention.
  • a plurality of wire pairs arranged in parallel, for example, according to FIG. 2, the wire pairs 10 to 14, are formed with the aid of holding elements 15 running transversely to the wire longitudinal direction to form a flat cable.
  • the holding elements 15 are arranged on one side to the wire pairs 10 to 14 and glued or welded to the insulation of the wires. As a result of a continuously running manufacturing process, the holding elements 15 do not run perpendicular to the longitudinal direction of the wire, but at an angle to it.
  • a core group consisting of the core pairs 10 to 14 is produced with the manufacturing device shown schematically in FIG. 3.
  • This essentially contains a fixedly arranged perforated disk 20 which, as shown in FIG. 4, has guide holes 21 symmetrical to its axis for guiding the wire pairs 10 to 14 and behind which a cylindrical mandrel 22 extending in the axis of the perforated disk is arranged.
  • a central spinner 23 is arranged concentrically with this mandrel and at the same time contains a disk-shaped guide piece for fixing the wire pairs 10 to 14 on the surface lines of the cylindrical mandrel 22.
  • a holding helix 15 ' is spun onto the wire pairs 10 to 14 and, after leaving the spinner arm 24, passes through a device 25 rotating with the spinner for applying an adhesive to the holding helix 15.
  • the holding spiral 15 sticks to the Surface of the wire pairs 10 to 14, the solvent of the adhesive being vented off by means of a venting device 26.
  • a cutting device 27 is arranged behind the end of the mandrel 22, by means of which the holding spiral 15 is separated between two wire pairs. This completes the formation of the wire pairs 10 to 14 into a flat cable.
  • This can be formed into a basic bundle using known devices to be subsequently arranged, for example by folding or by spiral winding, as is shown schematically in FIGS. 5 and 6 for a basic bundle consisting of seven wire pairs, and twisted or stranded.
  • the flat cable came to be twisted or stranded directly to the base bundle.
  • an SZ stranding device known per se, not shown in detail, is expediently arranged in front of the perforated disk 20, which twists the wires running from spatially arranged wire supplies to the wire pairs 10 to 14.
  • each round basic bundle can be broken down again and shaped back into a flat cable according to FIG. 2.
  • the individual wire pairs no longer need to be identified, since their counting sequence results from the geometry of the flat cable.
  • a distinction between the a and b wires of individual wire pairs can be made, for example, by colouration or other indicators.
  • the counting direction within a flat cable can also be specified, for example, by means of a colored border marking.
