Problems solved by technology

The general practice is to use potting to strengthen the anti-vibration of the device. The problem is that potting greatly increases the weight of the component and reduces the maintainability of the component.
At the same time, the installation method of the hard connection is basically fixed in a single dimension. For the vibration and impact of multiple dimensions from the carrier, there is often a problem in a certain direction.
[0005] The airborne environment is relatively harsh, and there are problems such as low air pressure and moisture. The traditional method is to use the sealing method of the component box. While the sealed box solves the problems of low air pressure and moisture, it will also bring two Negative effects from one aspect: On the one hand, such sealed boxes are generally interconnected by cables, which will increase the weight, volume and complexity of the components; on the other hand, the sealed boxes can only be cooled by indirect air, which involves secondary Heat transfer, heat transfer efficiency is relatively low

Abstract

The invention discloses an airborne high-reliability SAM assembly, which includes a box body, the box body includes two end faces of the front and the back, the box body is provided with a placement cavity, and the placement cavity is provided with a power divider and a printed circuit board. board, the side wall of the placement cavity is provided with a floating blind-mating connector, and the printed board is connected to the TR assembly arranged on the front through the floating blind-mating connector; the present invention implements the described Guiding, fixing and locking of SAM components, that is: guide rails are roughly positioned and guided, guide pins are precisely guided, the front end of the captive screw is fixed, and finally reinforced with a wedge-shaped locking device; this mode does not increase the installation space. In this way, the anti-vibration performance of the components is enhanced to meet the airborne vibration environment, and at the same time, the problem of excessive weight caused by potting and other design requirements inside the box is avoided.

Description

technical field [0001] The invention relates to the technical field of microwave transceiver components, in particular to an airborne high-reliability SAM component. Background technique [0002] With the rapid advancement of high-tech technologies such as digital simulation technology and microelectronic information computers, modern aircraft have undertaken functional tasks such as supersonic cruise, high-mobility stealth, and all-weather combat. Due to the increase in the working intensity of the aircraft and the deterioration of the environment, the airborne electronic equipment will inevitably face a worse working environment than before. These changes pose all-round challenges to the airborne electronic equipment. Under the premise of quantification, the functions are highly integrated and have high precision and reliability. This creates a contradiction. On the one hand, due to the size limitation of the electronic equipment and its auxiliary structures, the electron...
