ABSTRACT:
A flexible current feeding post for electronic modular assemblies interconnects parallel oriented substrates such as printed circuit boards having electrical circuits mounted thereon and bus plates for power supply, for both mechanical assembly and current distribution. The flexible current feeding post comprises a solid, cylindrical stud for connection to a contact surface of one substrate, a conductive bellows connected to the stud and means connecting the conductive bellows to a contact surface of a second substrate, spaced from the first substrate by a desired distance and generally parallel thereto. The flexible current feeding post affords tolerances with respect to mechanical misalignment of the respective contact surfaces of the interconnected substrates and spacing variations therebetween, thus eliminating undesirable distortion of the interconnected substrates and affording enhanced tolerance to thermal distortions of the substrates during operation, and assuring intimate and uniform connections of the feeding post to the corresponding contact surfaces of the substrates to minimize voltage drops thereacross. Flexible current by-pass means are afforded to increase the current handling capacity of the feeding post.
