Putting this out there in case I'm overlooking an issue



For the few D-sub machined pins that I've needed to install, I have soldered 22 awg to them and put some heatshrink over the top of the pin and the wire insulation. Still fits into the hole of the plug. 



I know that this makes a less flexible connection than a crimp, but with the heatshrink over the pin and wire in addition to the backshell clamping the wire bundle, I think that vibration isolation has been properly addressed.



What say you more experienced electronic folk?

    Crimps and solder are for all practical

    purposes interchangeable . . .

    I've soldered many a machined pin without

    regard or concern for extra-ordinary vibration

    isolation. Reduction of stress due to vibration

    comes from bundle support in the D-sub hood.
