desired fig7 illustrates schematically how the opposed beam members 30 when compressed can overlap thus providing a range of movement exceeding the gap width 24 as one example which is not to be considered limiting for a 0 045 inches pin the gap width 24 is about 0 008 inches the peak center lines are offset by about 0 011 inches and the allowed lateral movement 24a before abutment occurs is about 0 016 inches preferably the clearance width 24a of the conforming section for the example given is such that the conforming section must be approximately 0 014 inches minimum to allow for u00b1 0 005 inches plated through hole tolerance conforming section manufacturing tolerance and residual spring force during soldering the length of the conforming section designated 56 in fig1 is chosen to provide a low power spring rate as defined below for the pin examples given the preferred length 56 of each of the opposed beam members is about 0 070 inches for a pin with a nominal dimension of 0 018 inches about 0 125 inches for a pin with a nominal dimension of 0 025 inches and about 0 240 inches for a pin with a nominal dimension of 0 045 inches for plated through hole sizes and tolerance of 0 023 u00b1 0 003 inches for a pin with a nominal dimension of 0 018 inches 0 038 u00b1 0 005 inches for a pin with a nominal dimension of 0 025 inches and.
