The electronic device in which the harness is used consists of packages 1 of stacked printed circuit boards 2 fixed through racks 3 to the base 4 (Fig. 1).

The interboard electrical interconnection of the radio electronic device is made by a harness 5 of the electric wire 6, attached to a flexible continuous thread 7 (Fig. 1, 2, 11).

water for electromechanical fixing to the printed contacts 13, for example by soldering (Fig. 11, 13), and by welding (Fig. 10, 12, 14, 15).

The location of the trunks 9 (Fig. 3) in the harness is made with the formation of connecting elements located between adjacent dies diagonally so that they bend in arrow 14 (Fig. 5, 6) or in rotation in arrow 15 (Fig. 7, B) The harness can be transformed into a single day of all the matrices of the electronic device plane 16 (Fig. 9) with the perpendicular arrangement of the branches 11 in two rows 10. The matrix 8 contains only intersecting inter-board electrical interconnection (Fig. 4).

The harness has a volumetric shape of its elements.

The template for laying wires into a bundle contains a hollow laying needle 17 with wire 6 on the coil 18, bringing 19-21 coordinate displacements in three dimensions of space from the programmer 22 of the computer 23 and the base 25 rotating around the axis 24 also from the computer-controlled drive 26 (Fig. 16).

The template base comprises mounting states 27 and 28 with guides 29 in holes 30 to facilitate plane-parallel, if necessary, approach and return, circuit board springs 31 and spacer block 32 (Fig. 19):

On the end surfaces of the circuit boards there are grooves 33 with dimensions of 34, protrusions 35, equal to the corresponding posts of the electronic unit.

Along the walls of the grooves 33 on the protrusions 35 of the block, the pins 36 are fixed in accordance with the spacing of the printed contacts on the printed circuit boards of the electronic unit. On the inner sides 37 and 38 of the protrusions of the circuit boards with an offset of half the pitch of the pins 36, the pins 39 are installed (Fig. 16, 18).

It is possible to execute mounting plates 27 and 28 in a removable version of the protrusions 35 on the hinges 40 of rotation with a fastening latch 41 for a series of operations of making a tow (Fig. 20, 21).

The program carrier 22 and the device template base are provided for

simultaneous manufacture of two tows deployed in the plane (Fig. 17), however, it is possible to manufacture one of the tows on the corresponding template base (Fig. 22).

Preparing a harness fabrication device consists of working out a computer program for continuously laying out the electrical wire at the same time of two strands on the x-bases 27 and 28 in the sequence of ending the unfolded circuit of one bundle and beginning of the opposite circuit of the other bundle, installing a coil with wire, charging the computer with the program, setting the wires of the three-axis movement and the mandrel-, the template to the initial position of the first circuit, filling the end of the electrical wire into the hollow switchboard needle and attachment to one of the template mandrel pins.

The pattern for wiring the harness is used as follows. The coordinate displacement of a hollow needle with a wire controlled by a program from a program carrier, winds the wire from the coil 18 and places it across the interphase spaces of one of the plane-bases 27 from the beginning of the folding of my electrical circuit to the end (Fig. 16),

Next, the template base is driven 26

the stacking needle 17 rotates and transfers the wire from the plane of the base 27 to the circuit board 28, orienting the layout of the wire with the pins 39 to the coordinate of the beginning of the electric circuit

another harness being manufactured (Fig. 18). The alternating layout of the electrical circuits of various harnesses ensures that the electrical installation wire is tightly placed both in the matrices and in the branches with the orientation of the ends of the chains in the future at the planned coordinate address points.

After all the chains have been laid out, the locking struts 32 of the mandrel-template are removed and the operation is carried out. in zki trunks and branches of the harness. Resizing is compressed by the mutual movement of the base planes.

The viscous operation of the shafts and branches of the harness is replaced by the operation of fixing the wires relative to each other in a strictly stable state. At the same time, for the convenience of approach, the protrusions 35 of the circuit boards are freed from fic

41. The mobility of inter-gap gaps is also used in the organized group preparation of conducting veins for installation, cutting the continuous wire and removing the finished bundle for subsequent assembly and installation work of the installation in an electronic device,

Cords with the volumetric shape of the matrices, shafts, taps and ends of wires that can be transformed in shape into a continuous plane are most suitable for integrated automation of manufacturing technology operations.

The design of the electrical interconnection of radio electronic components of radioelectronic equipment simplifies layout

, design development problems.

A template for laying out wires in a harness with controlling the process of laying out wires, towers and taps, preparing and attaching the ends of the wires of an electronic computer from a program carrier to a pair-wise program increases productivity, and the movable constructs of the template provide access to the zone of operations with wire.
