Horizontal plugboard type aerospace integrated electronic single machine structure

Abstract

The invention discloses a horizontal plugboard type aerospace integrated electronic single machine structure which includes a shell, functional modules, a motherboard and an auxiliary reinforcement part. The functional modules and the motherboard are installed inside the shell. The functional modules are horizontally installed and can be horizontally inserted and pulled. The motherboard is vertically installed and is perpendicular to the functional modules. Through mating bus plugs on functional printed boards in the functional modules and a bus socket on the motherboard, the functions of power supply and communication are achieved. The shell is formed by a guide plate, a side plate, a panel and a base plate, the shell and the auxiliary reinforcement parts are fastened by corresponding screws to form an entire machine. The horizontal plugboard type aerospace integrated electronic single machine structure has the advantages of a compact structure, a harmonious proportion, a reasonable position of the center of gravity, high strength, good heat dissipation and easy disassembly, the functional modules can be freely plugged, the debugging is facilitated, the structure is applicable toa single machine with each functional module connected to the motherboard via a connector bus, a small number of functional modules and a minimum height dimension. The structure can be applied to alltypes of aerospace integrated electronic single machine products that meet the above conditions.

Description

technical field [0001] The present invention relates to the technical field of aerospace stand-alone products, in particular to a transverse plug-in type aerospace integrated electronic stand-alone structure. Background technique [0002] With the wide application of computers in avionics systems, bus technology came into being. The emergence of bus technology is the result of overall design of avionics systems from the perspective of system engineering. The network realizes the effective transmission and sharing of information, realizes the comprehensive display and control of the cockpit, and thus forms an integrated avionics system. [0003] At present, most of the stand-alone structures of aerospace integrated electronics in the traditional connector bus technology are vertical plug-in type, that is, the functional modules are installed vertically, and the motherboard is installed horizontally. When the number of functional printed board modules is small, it is easy to ...

AI Technical Summary

Problems solved by technology

When the number of functional printed board modules is small, it is easy to cause the height dimension of the stand-alone machine to be larger than the length or width direction dimension, causing the whole stand-alone appearance to be out of balance and the center of gravity too high, thereby reducing the environmental adaptability of the system and failing to meet the development requirements of the system

In addition, the area of ​​the heat dissipation bottom plate is too small, which is not conducive to the stand-alone machine passing various mechanical and thermal tests, and after being installed on the whole star, the external connectors in the height direction are likely to interfere with other machines, thereby reducing the electromagnetic compatibility of the system and Reliability of system signal transmission, etc.
