Hi,

I'm looking for a production suitable method of getting USB cables into a sealed 
enclosure, IP65 or thereabouts. Cables are required to be installed in the field - at 
least once in the lifetime of the equipment, but are seldom removed. Would like to 
use off the shelf USB cables if possible and avoid re-termination of connectors. 
Special waterproof USB A plug/receptacles could be used and pre-terminated 
cables could be supplied, but that's an expensive option.

I have seen off the shelf USB cables with the USB type A plug trimmed down a bit 
and passed through a standard plastic threaded gland into an enclosure. Trouble is 
it needs a way oversized gland, proper cable sealing becomes difficult, and I don't 
like the idea of the installer having to whittle away the overmoulded plug.

Just wondering if anyone has any cunning ideas for this? I can almost envisage 
what a special USB cable gland might look like... a rectangular hole to pass the 
USB A plug through, two piece rubber seals that seal rectangular hole to round 
cable, and (this is the really hard part) some kind of a two piece snap together 
locking nut that assembles around the cable and tightens into the gland. The 
assumption is that it's not possible to slide the gland components on from the other 
end of the cable.
