Abstract: The space among the integrated layers of airborne radar is narrow and the device layout is dense. The structure of realizing the interconnection of modules and components in the limited space is complex and the assembly process is difficult. However, the docking area of conventional wire docking methods such as distributor ring switching, solder ring docking, U-shaped soldering and other connection methods is about 30 mm, which can not meet the multi-point interconnection of electrical signals in the highly integrated space. In this paper, a switching method of miniature highly integrated compressible, cable assembly of interconnected array based on embedded miniature circuit board is proposed, which innovatively introduces miniature circuit board into the cable assembly. The miniature circuit board is used as the switching medium to realize the multi-hole switching of the cable assembly. At the same time, the wire bundle of the cable assembly is preformed to allow the electric connector head to float and stretch, and the function of compressibility is realized. Interconnected array can be realized through multiple combinations of cable assembly, which solves the problem of high reliability of electrical signal connection in a low space and high density and highly integrated cable interconnection in the integrated layer of airborne radar.
