Looking for a 2 hole snap on wire grommet

[Jamie]

I would like to pair up some RG-174 used in a bridge instrument as
leads to the clips.
I want to be able to pair off the two clips however, what I would
like is a snap on wire clasp with 2 guide holes to hold the
two coaxes together as single lead or, just a oval channel would
be fine.. This is to have no sharp edges and design to be exposed
to users.

It would be nice if it could wrap around the two cables and snap
together, so that later it could be un snapped to replace a coax
if needed, or if they are cheap enough we could just snap on new
one.

This is sort of like a ladder line grouping fastener but I don't
need the spacing as such and should have no provided holes for panel
mountings.. sort of like a wrap around snap on grommet.


Does any one have a name for this?

What you probably need is a D-type mixed signal connector with a
couple of coaxial inserts. Most of them seemed to be designed to work
with RG-174, but we used them with semi-rigid coax and "conformable
coax" when we were being hyper-careful with our high-frequency
signals.

You can put a socket into the front panel and plug an ordered group of
coax cables into it, and use the usual D-type connector locks to keep
everything together.

If you've got lots of coax cables, mixed-signal DIN-41612 connectors
can accommodate more of them.

If you described what you were trying to do in a little more detail,
one might be able to be more helpful.

What on earth are "the clips" doing? Just grabbing the outside of the
cables?

Yes bill, I simply want to pair some RG-174. I have 6 feet of 2 pairs,
each pair is a connection to the bridge circuit, I need to keep these
pairs from getting tangled since all four coaxes are coming out of a
module plug and the outer 2's need to be paired for each clip.

I want to use removeable/replaceable bonnet type clips when it comes
time to replace a coax, which it will happen..

For now, the prototype will be using neoprene O-rings.. At least they
can make adjustments to the spaceing at the end before the kelvin clips

So tie the outer 2's together by feeding them through two separate
mixed-signal D-type connector bodies

You can fill the third gap with a power connector pin to make sure the
two connectors aren't identical and thus can't be plugged in in the
wrong order.

What's wrong with cable ties? You'd have to discard them when you
wanted to discard the coaxial cable, but they are a lot cheaper than
coax. You can figure-of-eight loop them if you don't want to risk
distorting the coaxial cable.

Why knot use paired RG-174?

I've had to deal with phase matching coax cables and the dual stuff
works nicely (when cut from the same roll of cable).

I've also snaked two coax cables through a length of shrink tube to
make a dual coax assembly. Not recommended because it tends to look
sloppy.

You know, I work at a place that makes wire! I never thought of that and
also, I don't remember that ever being made as long as I have worked for
them over the years, at least the RG-174 line. (Brand Rex), BiccGeneral,
Bicc, Continental and now General Cable.

That is a good idea and I think I'll have to sit down on the computer
tomorrow to check the warehouses for stock in other locations, I know we
don't have in our location. IF that does not pan out, then we'll just
buy from a competitor

Thanks.

Twisted pairs, just like regular signal cable; heatshrink-banded ends,
prior to leaddressing or termination.
