Abstract

A METHOD OF MANUFACTURING CODE HARNESSES, which involves laying the wires on the templates installed in a row with pads, for example, on a flexible tape, sticking the wires and removing them from the templates, so that . In order to simplify the production of a code bundle, in the process of laying the wires on the templates, they are formed into groups with the formation of a loop in each wire, the ends of the open loop are unsoldered to the corresponding contacts of the block after the wires are fastened in a cable, and then after the bonded wires are removed with templates nez The looped loops are cut, the resulting wire ends are combined into appropriate groups, and then the jumpers between the contacts are removed, for example, by burning out.

Description

1I

The invention relates to computing and can be used in the manufacture of transformer-type permanent storage devices for digital computers.

A known method of making code bundles for transformer memory devices (memories) of a digital computer consists of laying a wire with a hollow needle on the templates CO.

A disadvantage of the known method is the necessity of fixing the ends of the wire on the address pins of the patterns, and then unzipping these ends into diode arrays. This complicates the technology of making code strands.

The closest to the technical essence of the invention is a method of making harnesses 2, concluded in laying the wire with a hollow needle on the template-frames, installed in a row with pads on the cylindrical surface of the drum when turning the drum and moving the end of the needle between the projections of the templates with a curved path .

After completion of the operation, the layouts of the wires of the framework-skeleton cavities are closed by heating the graded and coded cords that retain the firmware structure, are removed from the carrier tape to undergo further operations. Frameworks remain in the bundle already as group frames, which are an integral part of the tow.

The disadvantage of this method is the relatively small code capacity due to the presence of frames, which reduces the number of wires in the windows of transformers, and consequently, the capacity of the entire storage device, as well as the long trace time of the wire, as the ends of the wires are fixed on two pads the beginning and end of the harness.

The purpose of the invention is to simplify the technology of manufacturing code guta.

This goal is achieved by the fact that, according to the method of manufacturing code harnesses, it is necessary to lay the wires on the templates installed in a row with pads, for example, on a flexible tape, to fasten the wires and remove them

from the templates, in the process of laying the wires on the templates they are formed into groups with the formation of an open loop in each wire, the ends are unclosed, that loop is unsoldered to the corresponding pins after binding the wires to a harness, and then after removing the bonded wires from the templates, open cut loops ( The ends of the wires are combined into corresponding groups and then the jumpers between the contacts, for example, burning, are removed.

5 Figure 1 shows a device that implements the proposed method; on figa - elements of the code harness on a flexible tape with curly patterns; on Fig. 26 and in - direction Q tracing of the groups of wires and the formation of 1, P, III and 1Y groups of wires; Fig. 2d shows the position of the groups of wires at the end of the bundle after removing them from the templates.

5 On the thin elastic tape 1, set and fix the figured ribbons 2 and the block 3, then the tape 1. fix on the cylindrical one. the surface of the drum 4, kinematically connected with the electric drive 5. The wire 6 from the coil 7 is passed inside the hollow needle 8, which is moved by the electric drive 9. The movement of the needle 8 around the pins of the pins 3 is driven 10. The drives 5.9 and 10 are mounted from software block 11. Wires are placed between the protrusions of 12 shaped patterns that form with the base of the Shyblon cavity 13 for the wire (Fig. 2a). Block 3 is made of an elastic insulating material with metal pins 14, on which the beginnings of the apertures are fixed, the ends of the wire are laid in groups 15 between the projections of the templates. The number of wires in a group is determined by the structural scheme of the decoder, namely the number of columns and rows of the decoder,

Each line of the decoder corresponds to one group of wires.

Code cords include harness wires, retaining tracing structure 5, and one block 3.

Manufacturing code harness drives. The ROM of the digital computer is produced in the following sequence. Before stitching the wires, the templates 2 are fixed and secured to the tape 3 on the tape 1, which is fixed to the cylindrical surface of the drum 4. The wire 6, passed through the hollow needle 8, is fixed at the beginning. harness on the tape 1. Then they lay (pierce) the wires inside the cavity 13 of the templates 2. The movement of the drum 4 with the tape 1 and the needle 8 is consistent with time — when the drum moves, the needle is stationary and, depending on the program, is in one of the two extreme positions corresponding to 1 or O of the code being flashed. When the needle of the bar is moved, the ban with the ribbon is fixed. When the tape is rotated, the needle end passes through the cavities of the 13 patterns, and when the needle moves, the protrusions 12 move along the curvilinear trajectory, the envelope of the wire, laid in the cavities of the patterns where they cross. In Fig. 2a (section A-A), the dotted line 16 shows the trajectory of the end of the needle in a vertical plane. After laying the first wire into the internal cavities of all the patterns I i, the wire is fixed on the first pin of the pad 3 by twisting it. In order to ensure the continuity of the wire routing process after fixing the end of one wire on the pad pin, the needle is transferred from wire 6 to the adjacent lower pin and after it is wound, the trace of the next wire continues. At the same time, jumpers 17 (Fig. 2a) are formed between the vertical pins of the pads, wires are placed into the internal cavities 13 from the other end, skirting the end templates 2 (unlike the prototype, where the pins of the second pad are wired) and providing continuous tracer wire 6 with the reverse course of the ba-. raban Further, the continuity of the wire 6 is not disturbed, the beginning of the next CODE cable is fixed on the corresponding pin of the pad 3 by wrapping, and the trace of the wire 6 continues in the cavities of the templates, as indicated. In this example, four groups of wires are formed on the opposite end of the harness (fig. 26, c, d). After laying all the wires, the tape 1 is removed from the drum 4 in the form of a rim and fastened the wires in the bundle by gluing or tying the wires with threads, keeping the firmware structure. Next, the tape is straightened, removable templates are removed, and the loose harness (pad and associated coding wires) is removed from the tape. Wires, wound on pins x pads 3, are soldered to the corresponding pins m, jumpers 17 between pins m 14 are burned. The end of the harness opposite to the block is cut along line 18, which envelops the outermost templates, thus forming separate groups of wires in the form of bundles of wires of appropriate length, the wires in which are soldered together, for example, by dipping in liquid solder. The finished cable is checked for openings and short circuits and installed so that the tires of the drive column decoder are connected to the corresponding pin pads, and the wires themselves are put on the ferrite cores of the transformer cores, the groups of wire ends soldered to a single point inside the group are connected to the outputs of the drive line decoder. Using the proposed method of manufacturing code harnesses compared to lime and allows you to increase the code capacity of the harness without increasing its size and reduce the complexity of manufacturing the harnesses, because with the removal of the frames, the thickness of the harness decreases and there is no need to manufacture frame patterns, to reduce the trace time of the wire harness , since with the removal of one block there is no need to fasten the wire to it.
