The invention relates to one of the branches of the electrical industry - cable technique, and more specifically to a miniature electrical control cables for wired line communication (PLC) small guided missiles with the command control system and method of its manufacture.

Currently, widespread small guided missiles, which for remote telecommunications and transmission of control commands from the ground control equipment (NAU) on Board the missile uses a wire communication line in the form of a two conductor electrical cable. Thus, produced NAU control commands are sent on Board the guided missile, which ensures the correction of its spatial position in the process of targeting during the entire flight time.

Modern conditions of use of guided missiles, which have a PLC dictate rather strict technical requirements for this type of weapons. It is, first and foremost, ensuring the minimum outer diameter of the cable PLC, providing a minimum mass of winding PLC with simultaneous maximum length of electrical cable, according to the strength of the cable PLC highest standards of effort to break. Also rather high requirements for electrical Hara is the local cable PLC, especially in extreme conditions of combat use of guided missiles.

Known electrical cable [1], providing high performance in terms of periodic improving the mechanical and temperature effects on the external environment, which is an analog of the present invention. This cable contains located in the same plane as the conductors, each of which has a two-layer insulation compositions based on high density polyethylene (HDPE), a pillow under armor in the form of rubberized fabric and the overall armor of the steel strip, thus it contains an additional element isolation made of two PTFE tape, applied with an overlap of 30-50% on the inner insulation layer of the composition on the basis of PAST.

The method of manufacture described cable is as follows. The copper core cross-section 16 mm2isolate composition on the basis of PMT on the extruder with a diameter of start 125 mm, then insulating the car put two strips of Teflon with an overlap of 30-50%, and then isolate the second layer of PMT. On the insulated cores are laid in the same plane, put a pillow made of rubberized fabric and armor of steel tape.

The design of the cable while providing high electrical and mechanical strength characteristics has a large mass, invalid DL is used in PLC guided missiles.

Known miniature electric cable [2], taken as a prototype of the present invention. This cable is designed for control systems, data transmission and processing. The cable contains at least one pair of twisted between a conductive insulated conductors and the sheath. As the insulating material can be used galogensoderjasimi polymer - PVC or halogen-free material based on polyolefins - polyethylene and its copolymers or propylene. The proposed dependence of the thickness of the insulation from the pitch lived diameter lived and relative permittivity of the insulating material allowed while minimizing the Diametric dimensions of the cable to increase its capacitive workload.

However, the proposed design does not allow to provide the required parameters of the cable for small guided missiles for the minimum diameter of the cable, the minimum mass of winding PLC, the tensile strength and electrical parameters, especially in salt water.

The technical object of the present invention is to provide a construction of miniature control cable for PLC small guided missiles and method of its manufacture with the required electrical and mechanical characteristics, t is the train with its work under the direct immersion in water, including marine.

The essence of the invention is illustrated by drawings, where figure 1 shows a miniature cable management in the context, figure 2 shows a diagram of the fabrication of miniature control cable in machine OSM-3.

Miniature cable management is based (figure 1) consists of two electrically isolated from each other enamelled copper conductors (current-carrying conductors) 1 diameter of about 0.071 mm, one reinforcing multifilament yarn SVM-based synthetic high-molecular compounds nominal linear density of 6.3 Tex, parallel copper conductors 1, transverse fastening coil 3 pasmo of three nylon threads nominal linear density of 5 Tex, forming a harness, as well as seven reinforcing filament yarn 4 nominal linear density of 6.3 Tex placed on the fastening coil 3 in parallel copper conductors 1, and the secondary fastening of the winding of one reinforcing multifilament yarn 6 nominal linear density of 6.3 Tex laid with the step of winding of 0.7 mm, While the braid is formed copper conductors, one reinforcing comprehensive thread and transverse fastening winding impregnated hydrophobic liquid, mainly brand 136-41 GOST 10834-76.

A method of manufacturing a miniature cable management provides for its production in two successive stages. The first stage of the manufacture of harness, the second production of the cable itself. It uses a special machine brand OSM-3 with a linear speed of 3.5-4.5 m/min

Scheme of cable manufacturing are presented in figure 2. Two enameled copper conductor 1 with a diameter of about 0.071 mm with two coils 7 and strengthening complex thread 2 with coil 8 combine, keeping them parallel, PR is allowed to pass through the tray 9 with the hydrophobic liquid brand 136-41 GOST 10834-76 with a kinematic viscosity of 50-165 mm 2/from and through the top of the wrapper 10 impose primary fastening the winding 3 pasmo of three polyamide fibers 11 with a pitch of 0.7 mm, impregnated also hydrophobic liquid. This provides tension enameled conductors in the range of 0.29 to 0.58 N, the tension reinforcing multifilament yarn 2 in the range of 0.39-0.58 N, the tension of the wrapping pasmi in the range of 0.24-0,49 N. After this harness is dried in furnace 12 at a temperature of 120-150 degrees Celsius.

At the same time provide tension reinforcing filament yarn 4 in the range of 0.58-0,78 N, and the harness is within 1,47 is 1.96. After that, using the average of the wrapper 16 top impose a single-layer winding pasmo with calculation step of 0.7 mm from one reinforcing multifilament yarn 6 by providing tension winding pasmi in the range of 0.58-0,78 N.

Thus obtained miniature cable management through the pulling device 17 is wound on the take-up spool 18.

The proposed device in addition to describing the design of miniature control cable and method of manufacture consists in the following. The parallel arrangement of the conductive isolera the data copper conductors and one reinforcing multifilament yarn combined with a pre-styling process by loading the tensile strength in the range of elastic deformation of the material provides a significant increase in axial resistance harness to break through the internal axial force pre-load, and eliminating all kinds of hub forces in the form of loops in the manufacture of harness. The design of the harness allows the use of modern synthetic macromolecular compounds [3] domestic producers with high tensile strength, virtually eliminating the loading tensile force of the conductive wires. Fastening the winding pasmo of three polyamide filaments to provide with regard to the hydrophobic impregnation liquid and drying the production of a single, monolithic, flexible conductive braid. The temperature of drying is selected from the condition of internal stress of the power elements of the harness and the optimal mode of polymerization of the hydrophobic liquid. Thus obtained harness is hardened in the axial direction even family strengthening complex threads placed parallel to the harness, and lapped pasmo of loaded axial-force reinforcing comprehensive thread, thereby providing a solid bunch of items miniature cable management. Superimposed on top of the reinforcing complex thread protects the elements of the miniature control cable from mechanical and thermal effects during the start of the guided missile, and the process of its flight.
