Description

The invention relates to electrical engineering, mainly cable technology, namely to woven ribbon cables.

A woven ribbon cable with contact loops is known, the distinguishing features of which are the use of elastic yarns 17 as the weft.

The disadvantage of this cable is the unevenness of the shrinking of electric wires with elastic yarns, the instability of the cable structure in the longitudinal and transverse directions, the breakdown of the structure of the bindings at the points of bending or withdrawal of the contact loops.

Closest to the invention is a woven ribbon cable with contact leads, which in its structure on the basis contains meisolated electrical conductors and insulating bridging NITI; I intertwine separately with the dielectric filaments to-sh, to protect the electrical conductors from the external environment and intersect a lot of short-circuiting C2.

The disadvantage is that it is impossible to produce a cable with certain intervals between loopback waters along the length of the cable.

The disadvantages are also the unconstructiveness of the cable g, which is expressed in its inflection according to good. and folding with the aim of outputting contact loops on the front side, to the orchest of the outer 3 o1;,. Pysok material consumption and production rate and similar raw materials,

The aim of the invention is to increase the reliability and high-tech woven ribbon cable,

The goal is achieved by the fact that the ribbon cable is connected to the ribbon cable. The webs are twisted, the weaving insulating threads and the base threads, the eletroprobo day: they belong to a group of contact wires made of electrical conductor, 3 pile loops, the threads are used as a weft from a thermoplastic material, and as a basis - monoliths from the same material, while the monofilaments are located at the points of contact with it and the duct, and electrophobic; the tubes are parallel to the cone, have a diameter smaller than the diameter of the mokonity, and placed in rhombone in the places of geometric crossing of pairs of weft yarns of joining-thx opposite nozzles of grooves on the adjacent monokits x, with tucking loop tufts: to rDiocKOCTH cable and outlets; d t for:; p edges of the edge by the same values ;,

The laying of the weft yarns is carried out in the following sequence (Fig. 3). First, weft yarns 3 and 4 are laid, which make the electric conductors 2 on both sides o (and b), and then the weft threads 5 and 6 are laid parallel to each of the laid ones, the electrical conductors 2 are laid from the remaining sides c and d, after each in the case of weft yarns, the latter occupy an empty space in the image around the electrical conductors of the volume diamonds with sides a, b C and d. The order of laying the weft yarns can be changed (Fig. 4) weft yarns 3 and 4 are initially parallel with each other, with a shift on the magnitude of the diameter of the electrical conductor, making the electrical conductors 2 on the sides c and c, and then laying the parallel weft threads 5 and 6, covering the electrical conductors 2 on the remaining sides b and d. Considering that the electrical conductors 2 attract the mononiths to the opposite one m bases equal, but oppositely directed silgmi, the electrical conductors 2 in the structure of the cable remain linear, i.e. They do not alternately bend over and at the same time they are fastened with segments a, b, c and d of corresponding webs, and, the greater the force of tightening the weft threads, the better the electroconductors are covered and their protection from environmental influences. The clamping force of the weft yarns is directly proportional to their relative elongation that occurs at the time of formation of the structure, t around the monofilaments of the base 1, therefore, choosing about the diameters of the monofilament 1 is slightly larger than the diameters of the electrical conductors 2, the latter can be fixed with considerable efforts. As the continuous cable tape is produced, at certain points in its place, the contact elements in the form of pile loops 8 located in the plane perpendicular to the plane of the cable are drawn out of the electrical conductors 2, and each subsequent loop 8, B, ..., 8P is drawn higher than the previous one on the adjacent electrical conductor by the value of the interval between the electrical conductors. The foregoing can be written in the form of a formula., N is the height of the extraction of the loop being defined, the height of the loop on the previous conductor; serial number of the electrical conductor; i is the interval between the electrical conductors previous and defined. In the case when the intervals between the electrical conductors across the entire width of the cable are mutually interconnected, the height of the stretching of the loops is determined by the formula: Hf, -Ht i (hH) the height of the stretched loop; h is the order number of the conductor; B is the height of the loop on the first conductor; t is the interval between the conductors. The production of ribbon cables g with loop-outs can be carried out on a single-slot weaving machine 13 with a large filling width. Calculation of the machine refueling is performed based on the number of thermoplastic monofilaments 1 and uninsulated tinned electrical conductors 2 bases, which fall on the Пth number of cables laid on the entire filling width of the machine taking into account dividing strips 12, the size of which varies from 1 to 1.5 mm and depends from the required stiffness of the cable edges, since the separating strips are the material for their forge to; . 9 of a certain coded point of the tape 11 of all the first electric REMOTE of each cable is pulled out and the number of loops of the same height, and then for some 5 distances 2 along the length of the cables from the first loops, n loops are pulled out of the second electroconductors, but differing in height from loops on the electrical conductors on the value of t - the interval between the first and second. electric hornes, then h - loops from the third, etc., and as the distance from the dividing strips 12 increases, the height of the hinges from the electrical conductors increases until there is no

The length of the P loops of the last electroconductors is along the cable width.

At some distance from the edges. B of the produced tape 11 a set of chrome knives 17 is installed, to which a tension is applied from two sides. The knives 17 are located across the entire width of the tape 11E produced by the dividing strips 12 at distances determined by the width of the individual cables with respect to the edges 10. The heating temperature of the knives 17 is determined by the material of the weft yarns 3-6, taking into account that all weft yarns are made of polyester fibers , for example, lavsan, the temperature of warming up of the knives fluctuates within 280-300s. The knives 17 (Figs. 9 and 10 J) in the contact zone with the melted fabric have radial notches of variable cross section 18 in the cross section, which act as a wedge, separate and compact the melted material not only of the weft yarns, but also along one main thermoplastic monofilament 1, located on either side of a knife made of a dividing strip 12. Behind the knives 17, the molten material solidifies, forms monolithic radius edges 10 on both sides of the cables.

After the loops are folded with the copier 19 and the firmware on the device 20, the cable passes into the chamber 15 of thermoplastic processing, in which, under the influence of short-term heating, the main monofilaments 1 on the outer surface are put into a plastic state at a depth of 0.05-0.08 m. in the structure of the cables, they are made by bending the weft yarns around the monofilaments of the base, and the ZB threads themselves when forming the fabric were stretched to the maximum, on the outer surface of the monokite there are recesses 7 in the form of spherical segments, into which Do not thread the weft, the effort is removed,

temperature ra-5G) heating 180-200 ° C. The heating time is also determined depending on the starting materials of 1 s: s from the diameter and their diameter and can be regulated by the length of the heating zone and the speed of movement in the installation chamber 15. From the heating chamber of installation 15, the cables are passed to the stabilization chamber in which they are cooled. Bearing in mind that during thermoplastic processing only a fraction of the force of the weft threads is removed, i.e. only 10% of their elastic elongation is compensated, the structure, after stabilization, remains elastic, but with fixed weft threads in the recesses 7 of the monofilaments 1, and as a result, the selection of cables in the heating and stabilization zone is easily achieved the location of the loops along the length of the cable, since during heating the tension of the cables is lower than that of the outlet after the treatment.

If insulated electroconductors are used in cable production, thermoplastic weft thermoplastic can be used instead of thermoplastic weft yarn. similar mononite m foundations.

The invention simplifies the consistency of the cable and the technology of production by bringing konzaktnyh loops to its periphery without r; rigging the folding and folding operation, ensures better accuracy and reliability, as well as a reduction in material intensity and an increase in output and .
