Description

This invention relates to electrical engineering, in particular to cable technology, namely to the manufacture and use of tape bundles, and can be used in complex radio and electronic systems.

From the prior art (SU 486381 A, H01B 7/08, 10/11/1972, / 1 /), a flat braided cable is known that contains conductive conductors separately insulated and fastened together by threads (strands), and to increase the stability of conductive conductors when subjected to longitudinal loads and to increase the flexibility of the thread (strands) are located at an angle to the longitudinal axis of the cable within 30-75 ° and intersect each other.

This technical solution / 1 / allows you to connect several conductive wires into one weave using threads. However, no solution is provided for the possibility of subsequent effective separation of these cores.

From the prior art (SU 647747 A, H01B 7/08, 02/15/1979, / 2 /), a woven cable is known that consists of wires located across the entire width of the cable directly without gaps on the jumpers, fastened with wefts made of synthetic materials, located in waves With a small bending force, the weft threads bend around the wires and warp threads, which in turn are located between the two wires. They connect with the weft threads. To increase the reliability of the cable, an elastic thread is used as a weft.

When mounting blocks of electronic equipment, flat woven cables experience a number of mechanical deformations, which, due to the use of elastic threads in the weft, disappear after laying the cable at the installation site.

The above document / 2 / solves the problem of creating a single cable from wires using threads. The cable provides resistance to deformation with the help of weft threads, takes on voltage. However, no solution is provided for the possibility of subsequent effective separation of these cores.

From the prior art (WO 2012082847 A1, H01B 13/22, 06/21/2012, / 3 /), a single cable structure is known consisting of wires laid in recesses of the form. The wires are connected using a thread, the stitches of which are laid in special recesses of the form through a predetermined distance, thereby determining the specific connection point. The fabric covers the wires on top and is connected using a thread, thereby creating a single cable design.

The above document / 3 / solves the problem of creating a single cable by connecting it with a cloth and threads and its resistance to mechanical deformation by laying the cable into recesses of a strong shape. With this design of a single cable, it is possible to divide the cable into several conductive cores.

However, this technical solution / 3 / does not provide for the possibility of connecting additional or previously branched conductive wires to the tourniquet, has limited wiring, requires investment in additional equipment, is expensive, bulky, rigid (not flexible), and its implementation is associated with high labor costs due to design complexity.

The technical result of the invention is to eliminate the above drawbacks and create a compact, flexible, combined, durable, single cable that has the ability at any point in the bundle as branching and connecting conductive wires, wires or groups of wires, while maintaining its operational properties.

The technical result is achieved by the fact that the transposed flexible combined tape bundle, consisting of conductive conductors that are interconnected into a bundle with the possibility of branching conductive strands from the bundle, is characterized in that the ribbon bundle consists of individual elements in the form of ribbon cables containing conductive conductors or cables based on them, conductive wires or cables based on them are interconnected by a flexible connection using weaving or fabric, the individual elements are interconnected by a flexible cable linkage at predetermined portions and are able to harness the compound at any point along its length so that there is a possibility of branching on any subsequent plait portion, wherein the flexible link is adapted to retain the harness elements in the same plane.

In the development of the invention, weaving or fabric can be made of high-strength chemical thread, wire, tinsel threads and other materials.

A flexible connection can be made by thread or fibers or tinsel thread.

Unshielded wires, shielded wires without a sheath, shielded wires in a sheath or high-frequency coaxial cables, twisted pair, twisted pair in a screen, twisted pair in a screen and a sheath, other combinations of wires and cables can be used as current-carrying conductors of cables based on them.

As part of the bundle, drainage conductors or dielectric threads for stitching, hardening and marking can be arranged parallel to the conductive wires.

The individual elements of the harness can be reinforced at the ends with appropriate connectors for installation in equipment.

The above technical solution proposed by the applicant provides all the tasks, such as ensuring wiring from any position both across and along the length of the bundle, high flexibility in the longitudinal and transverse directions and high productivity in manufacturing, providing a combined design of the bundle in a wide range of use of conductive elements, for example, in one bundle there can be radio frequency cables, unshielded wires, twisted pair and drainage conductor, which each serve for its own about fundamentally different purposes, transmission of control signals, information, energy supply and communication. In this invention, the flexible connection provides the possibility of conveniently laying the cable in the apparatus with the subsequent branching of the conductive elements or groups of conductive elements on any segment of the bundle, which form a flexible ribbon element of the bundle. In addition, thanks to the flexible connection on any segment of the harness, it is possible to attach an additional harness or disconnect from the main one.

During operation, the tourniquet can be bent, including 360 °, withstand torsion and fold into a flexible rod.

Figure 1 presents the transposed flexible combined tape tourniquet.

The transposed flexible combined ribbon tourniquet consists of individual ribbon elements of the tourniquet (1), (2), (3), conductive cores (4), flexible ties (5) and weaving threads (6).

The conductive elements 4 of the tape element of the harness can be

- unshielded wires;

- shielded wires without sheath;

- shielded wires in the sheath;

- high-frequency coaxial cables;

- twisted pair;

- twisted pair in the screen;

- twisted pair in the screen and shell;

- other combinations of wires and cables;

- drainage conductors.

As part of a flexible connection, special flexible elements (threads, fibers, corbels, etc.) can also be present to fasten the tape elements of the bundle 1, 2, 3 to each other and increase elasticity, strength and resistance to a number of mechanical deformations.

Weaving or weaving can be made of high-strength chemically strong threads 5, wire, tinsel threads and other similar materials.

In one embodiment, good deformation resistance and high performance are ensured by the following design of the transposed flexible combined tape bundle, in which element 2 consists of six unshielded wires with a cross section of 0.35 mm, element 3 consists of two miniature RF cables with insulation diameter equal to 0.6 mm and a wave impedance of 50 Ohms with insulation and a sheath of 4MB fluoroplastic, element 1 consists of four twisted pairs with 4MB fluoroplastic insulation. Separate elements 1, 2, 3 are connected by a flexible connection, which is used as weaving with tinsel thread 6. On the edges of the elements 1, 2, 3 there are drainage conductors made of silver-plated copper wire to contact the braid (screen) of tinsel thread and provide a flexible connection between them. The total length of the tourniquet (element 1) is 5.2 m, the beginning of element 3 coincides with the beginning of element 1 (tourniquet) and has a length of 3.7 m, the beginning of element 2 is offset 1.4 m from the beginning of the tourniquet and has a length of 2 ,1m.

Thus, the present invention provides the elimination of the above / 1 /, / 2 /, / 3 / disadvantages and the creation of a combined, compact, flexible, durable, single harness with the possibility of branching conductive elements, wires or groups of wires, while maintaining its operational properties .
