Description

The invention relates to the field of electronic components, intended for use in on-board high-performance computing devices containing an extremely large number of wired communications (multiprocessor and neural systems).

Radio electronic blocks are known which comprise an extremely large number of wire connections and consist of a set of boards interconnected by means of detachable electrical connectors arranged uniformly along the plane of the board on both sides. Such electronic components (EW) have a large mass and dimensions of the machine, the package of EW boards can not be used separately from the machine unit.

Closest to the claimed EW is the EW, allowing the possibility of using a package of boards outside the machine tool unit. A special machine is used to connect and disconnect the boards during the repair process, which includes a housing and several jacks located (to allow removing electronic warfare from the machine) on the outside of the boards in areas adjacent to the corners of rectangular boards. Each of the machine jacks consists of a fixed housing, a lead screw, a nut, and a clutch member. When connecting and disconnecting the boards, one sludge board is attached to the fixed body of the jack, the other board is attached to the clutch element, mechanically rigidly connected to the nut of the jack. In the process of connecting the detachable connectors, the jack body and the clutch elements are compressed. To ensure mechanical stability, the clutch elements and jack housings are provided with additional stiffeners. The prototype machine is designed to perform complex repair work under stationary conditions, for which the length of the jackscrews of its jacks exceeds the length necessary only to remove the faulty board from the electronic warfare and replace it with a working one.

The disadvantages of the prototype are: 1) the large mass and dimensions of the prototype machine, due to the need to use several jacks, the presence of stiffeners on the clutch elements and jack bodies, the increased length of the spindles; said drawback substantially complicates or makes it impossible to carry out repair work on board aircraft and watercraft;

2) uneven load distribution in the prototype boards at the time the boards are connected requires additional mechanical rigidity

boards, as a result of which the thickness and weight of each individual board, and, consequently, the dimensions and weight of the entire package of boards as a whole, are significantly higher than in the first claimed block;

3) there is no possibility of compensating for bending deformations of the boards (arising, for example, when the boards are disconnected) during the connection of the boards, which sharply reduces the reliability of the electrical connection

between boards

4) the high cost of the prototype machine, due to the presence in the design of the machine a large number of precision jacks with an increased stroke length.

The aim of the invention is to reduce the size and weight of the electronic unit, increase its reliability, reduce cost.

The specified goal is achieved by the fact that

clutch elements with the boards are flexible, a pusher and stop are introduced, the contact areas of which with the extreme boards of the set of boards are evenly distributed over the entire area of the boards, the lead screw

the jack does not cross the plane of the boards and is located in the central part of the block; in the block tires fastening a set of boards, additional holes are made located opposite the ends of the boards, the machine

block is made in the form of a manual key.

Since the clutch element is not involved in the electrical connection of the boards in the first proposed electronic electronic unit (REB1) (the connection here is made using the pusher), the clutch elements work only in tear, so they can be made of lightweight flexible elements (for example,

thin red-hot steel strips, metal from kapron cables). The uniform distribution of the contact areas of the pusher with the board allows you to reduce the thickness of each individual board, which gives

the ability to significantly reduce the dimensions and weight of the package of boards of the inventive unit. The loss in mass due to the introduction of the pusher and the stop is completely compensated by the gain in mass obtained due to

lightening the machine frame, reducing the number of jacks, reducing the length of the spindle. In the second declared electronic block (REB2), a special manual key performs the function of the block machine,

dimensions and mass of which are repeatedly

smaller dimensions and mass of the prototype machine.

Figure 1 shows the first radio electronic unit (REB1); Fig. 2 shows a method for connecting a screw of a jack with a pusher and a machine frame, as well as a construction variant of a clutch cable element; in Fig. 3, the second inventive radio-electronic unit (REB2).

The electronic components consist of boards 1, buses 2 and devices for assembling and disassembling a package of boards. In REB1, a device for assembling and disassembling a package of boards (machine) includes a stand 3, a pusher 4, a support stand 5, guides b, a guide beam 7, bolts 8. clutch elements 9, a spindle 10, a handle 11 jacks, bolts 12, pins 13. In REB2, the device for assembling and disassembling the package of boards is made in the form of a hand wrench 14 consisting of a housing 15, a nut 16, a screw 17, a worm gear 18, handles 19 and 20. A cable clutch element REB1 contains a cable 21, a coil 22, a deadbolt 23, a handle-deadbolt 24; The coil 22 is secured to the pin 13 with a ball 25 and a spring 26.

Radio electronic blocks work as follows.

Before operation of the unit, all boards 1 are interconnected to form a single package of boards. In EW1, this package of boards can be operated with or without a block machine. In the latter case, tires 2 are superimposed on the docked package of boards and fastened to the boards by means of bolts 12, thereby the position of the boards 1 in the package is fixedly fixed. After that, the package of boards is removed from the machine of the block and can be used as part of another device. For repair, the beam-guide 7 is removed by unscrewing the bolts 8, the package of boards is mounted on the block machine on the guides 6, the beam-guide 7 is again attached to the posts 3 and 5. By removing the bolts 12, the tires 2 are removed. To remove the defective board from the package boards, three operations are required: 1) disconnect the defective board from the group of boards located between the defective board and rack 3; 2) disconnect the defective board from the group of boards located between the defective board and rack 5; 3) remove the guide 7.

To disconnect the defective board from the group of boards located between the defective board and the rack 3. The defective board from the garbage bin} of the bolts 12 and the elements 9 is mechanically connected to the pins 13 of the rack 5. The detachable group of boards is mechanically

communicates with the pusher 3 by coupling the end plate of the group (the board having common electrical connectors with the defective plate) by means of bolts 12 and other elements 9 with pins 13 of the pusher 3. Next, the spindle 10 is rotated by the handle 11 to move together with the pusher 3 and a detachable group of boards in the direction from the defective

boards. To disconnect the defective board from the group of cards located between the defective board and rack 5, the defective board is mechanically connected (using elements 9) to the pusher 3, and disconnect the e5 of the group of boards from the rack 5, then disconnect the rotary screw 10 to disconnect defective board from group board. In the case of using the cable clutch element (Fig. 2-b, c), the cable 21 is engaged with the board 1 by installing a deadbolt 23 inside the hole in the end of the board 1. The length of the cable is adjusted by rotating the coil 22 with the handle 24, previously

5 inserted into the hole on the coil 22. The position of the coil 22 on the pin 13 is fixed by installing a deadbolt 24 in the hole formed by the groove on the pin

13 and the groove located on the coil 22. 0 the assembly process of the package of cards is about

connection of the repaired circuit board with a group of circuit boards located between the repaired circuit board and rack 3, and with a group of circuit boards located between

5 by the repaired circuit board and rack 5. The repaired circuit board is mounted on rails 6 between the indicated groups of circuit boards, after which the ball guide 7 is attached to the racks 3 and 5. By rotating the winding 11, the pusher 4 is moved towards the counter support 5 until the electrical contacts of the plug connectors are fully connected. In the case of using a package of boards outside the machine

5, the assembled package of boards is superimposed on the busbars 2, bolted 12 to the boards 1, the 6s / 1 guide rail 7 is removed, and the package of boards is removed from the block machine.

In EW2, removing a defective board 1
