If you use HNC connectors instead of BNC the center pin will
be protected, and will, I believe, disconnect before the
shield disengages. This will eliminate HV hazards on
disconnect

Greetings,
We have a piece of lab equipment that uses 2kV to accelerate electrons
down a long tube. The top of the tube extends above the cabinet of the
product. This would not be too bad, except standard BNC connectors are
used to connect the HV to the top of the tube. This presents a shock
hazard if someone loosens one of the BNC connectors. The shape of this
item has made fabricating a metal cover very troublesome. A plastic
cover would have to be tooled, which means dollars and time for a low
volume product. So I'm looking for a way to secure these connectors
with a tool.
Has anyone seen covers that go over a BNC connector that screw
together?
Or...A design engineer also asked about using a cloth like material,
like kevlar, to cover the area that would also keep dust out. My UL
Engineer has not seen any material that would meet mechanical tests
for enclosures.
Thank you for your input. I've lost several hairs lately trying to
find a solution!
Regards,
Ray
