Description

The invention relates to the field of space technology and can be used in the construction of satellites for various purposes. The radio-electronic block of the space module is designed to control life support facilities (solar panels, power supplies, antennas, engines, etc.) and payload maintenance (transmitters-repeaters, cameras, scientific equipment).

Known radio-electronic unit of the space module containing two covers worn on the studs, composed of printed circuit boards, heat sinks, dividing frames and spring contacts of the cell of the electronic unit [1].

A disadvantage of the known design of the radio-electronic unit is that it does not allow to install (fasten) on its body the life support device and the payload of the space module, which leads to an increase in the volume and mass of the module due to the need to use a supporting frame.

In order to eliminate these drawbacks, the basic electronic unit further comprises load-bearing frame elements with mounting pads that are placed between the cells of the electronic unit, put on studs and tightened with nuts.

The technical result from the application of the invention is to expand the functionality of the electronic unit, as it allows the fastening of life support devices and the payload of the space module directly on its housing.

The invention is illustrated by drawings, in which:

Figure 1 - General view of the base carrier space module;

Figure 2 is a fragment of a radio electronic block in the context;

Figure 3 is an example of the placement of life support devices and payloads;

Figure 4 is a General view of the supporting frame element.

Figure 1-4 adopted the following notation:

1 - cell electronic unit

2 - printed circuit board

3 - heat sink

4 - dividing frame

5 - block connector

6 - spring contact

7 - supporting frame element

8 - mounting pad of the supporting frame element

9 - solar battery

10 - solar sensor

11 - external connector

12 - cover

13 - nut

14 - radio antenna

The basic electronic block contains a radio electronic block, consisting of a set (package) of cells 1 of the same design format. Each cell 1 includes a printed circuit board 2 with a metal heat sink 3, a dividing frame 4 with holes in which the pads 5 of the electrical connector of electrical insulation material with spring electrical contacts 7 are oval. Between the cells 1 of the electronic unit in the necessary places are placed the frame elements 7 with mounting platforms 8 for specific life support objects or payloads, for example, solar panels 9 and solar sensors 10.

The supporting frame element 7 is equipped with a printed circuit board and electrical connectors with spring contacts identical to the electrical connectors and circuit boards of the electronic unit.

The printed circuit board of the supporting frame element (not shown in the drawing) is a switching circuit, but it can also carry a functional load. The width of the supporting frame element 7 may vary depending on the size of the equipment installed on it and the dimensions of the external connectors 11. The package of cells of the electronic unit is closed by two covers 12, between which the cells are pulled together by means of tie-rods (pins (not shown) and nuts 13. On the covers 12 can also be attached any life support devices or payloads, for example, a radio antenna 14. This construction of the base electronic unit allows you to make its versatility and creates the opportunity to strengthen his body space module elements without the use of load-bearing frame. The inventive step of the proposed technical solution is confirmed by the distinctive part of the claims.
