Receptacles for tubes with flying leads

[Paul Andrews]

Hi,

I thought I would try the idea of using receptacles for tubes with flying leads, rather than soldering them directly to a board. I tired these from digikey, but they basically don't work. They provide no grip on the flying leads. I had checked the specs, i.e. the leads are 0.5mm, these receptacles are for 0.38mm ~ 0.64mm. Has anyone found any receptacles that work? I specifically liked these because they didn't have a tail.

Those receptacles are designed for hard pins; wire leads are much softer.

Hi. I use Mill-Max 9548, which is quite similar, in my Nixie watches. It works well. However, I also anchor the tubes in place with a piece of foam mounting tape. 

You might want to consider using a tube clamping bar with a small grommet at the top of each tube, held in place with a support structure on the rear.

I'm fond of the FCI "Minisert" line, which include elastomer to help keep things put in the case of vibration.  Tektronix used to use them as transistor sockets.  Unfortunately, they stopped making them (last shipment was May 2010).  I'll have to find something else to use at some point.
