Hello Folks,
Have to get a data cable of about 0.200" OD, round, through the side of
a plastic case. Does anyone make these for such small round cables?
http://www.richco-inc.com/products/grommets-and-bushings/107-grommets-bushings-catalog.html?PartNum=&country=RICHCOUSA&grpcode=K1310
Richco and others have theis other kind but they stick into the inside
by at least 1/3" which is a bit much:

To add insult to injury the side wall of the plastic case is not
straight, gets skinnier towards the top. Beats my why they do that. Hurumph!

Are you trying to protect the cable, dress it up, and/or provide
strain relief? (in the latter case, how *much* strain?)

The taper allows the case to be ejected from the mold.

Only strain relief would be needed. Not much, jusdt so it won't slip out
of the box. They won't do tractor-pulling contests with it :-)
It a wimpy cable, containing six 24AWG stranded wires.

Oh ... ahm, well, that would be me. But theye ain't that much out there
and then others I saw were tapered as well.

Understandable, but the enclosures we had injection-molded ourselves
were never tapered and none of the proto boxes I have here are. It makes
fastening single-hole stuff a pain. The selection isn't as rich anymore
as it was in the 80's.
Oh well, we'll just grind those areas flat. Not exactly fun with ABS but
must be done.

Yes, unfortunately they only have bulky monsters. 1" length or more. I
think we'll go with Richco.

We'd need thousands. Just had a chat with them and they are sending
samples. Here's why, and that blew me away: The required size for a
0.200" OD cable and drill diameters for thicker walls are not in the
drawing and not known to the support folks. "You'll have to try it out".
That gave me a chuckle.

What we usually use is something like one of the 700 series grommets
from:

and then tie off the cable on the inside of the box with a tiny
tie-wrap.

Yes, that and a tie wrap to the board could work. We are already using
the 778 (finned type) somewhere else. Good idea, John. I'll try to
provide both options, a board cut-out large enough to allow an LKG
Industries grommet and then four holes farther on for two tie wraps.
They may not like the tie wraps because of the prep-work. They'd have to
loop these through before the board gets mounted. Which would require a
staging area in production.

I meant just using a grommet and a tie-wrap tightened around the cable
jacket on the inside of the box, like this:

Sounds like the ideal grommet would be one that has a support tail on
one side and a tyewrap groove on the other side. Similar to those
used on re-wirable IEC connectors. In fact I have a box of 5000 of
them but they are 7.5mm bore. They were originally used for cable
strain relief on UK 13A plugs. I'll see if I can photograph one and
post a picture.

Yup! But sans the tail, because that'll really get in the way.

I've just submitted the design. Put two holes in the board so if need be
we can secure the cables on the board and run through a rubber grommet,
in case the squeeze-grommet doesn't pan out. Believe it or not, the
drawing misses some crucial info such as cable diameter ranges and the
mfg didn't know, and said we should try with samples. Almost fell off
the chair here.
