I'm looking for a few pieces of each of the following connectors. Solder
cup preferred, or crimp with pins. Used is OK as long as they can be
reused. These are in D-sub (DB) shells but with strange combinations
of pins. Some pins are fat for high current while others are normal size,
and one is a mini coax.

In the ASCII diagrams below, "O" is fat pin; "." is normal pin, "C" is
mini coax. Shells not shown.

7 pin male and female which look like:

. .
O . . . O (DB15 shell)

21 pin male and female which look like:

. . . . . . . .
O O . . . . . . . . . O O (DB37 shell)

5 pin male and female which look like:

O O O O C (DB25 shell)

I didn't see anything like these in Jameco or Digikey. Aside from looking
for a diagram that matches, I don't even know what to call them to search
properly. Or, perhaps they are custom.

Thanks.

Following up on my own post, I found the part - it's an Amphenol TW series
connector. Now all I need to do is find a distributor.

I know I've even had catalogs for this in my hands, but I can't
remember who makes them. I believe they are all customs, but I might
be wrong about that.

Googling for d-sub coax got me lots of hits. Finding the place that
will sell you a finite number will be the trick.

Usually there is some kind of trademark on the connector half that you
have that would get you moving in the right direction.

This might be Cannon's DAMC3H3PJK87, Newark PN 93F8924

5 pin male and female which look like:

O O O O C (DB25 shell)

Could be DBM5W5PK87, Newark PN 93F8910

In the 70's, we used connectors of this sort for military-contract
modems. As I recall, Amphenol and Cannon were the primary suppliers.
There are many different pin styles and layouts, mixing small signal,
power and coaxial (even fiber, today, I believe).

You're describing ITT/Cannon parts, Sam. More specifically, their
'Combo D' series. It's no surprise you couldn't find them in Jameco or
Digi-Key, because they're all mil-spec parts.

At the risk of some shameless self-promotion, I can get these for
you in small quantities (I have no minimum order).

http://www.bluefeathertech.com/connectors.html

You may also be able to get them through Allied or Newark, but
you're not likely to find them through any of the small distributors.

7 pin male and female which look like:

. .
O . . . O (DB15 shell)

That's a 7W2 pattern.

21 pin male and female which look like:

. . . . . . . .
O O . . . . . . . . . O O (DB37 shell)

That one's a 21WA4...

5 pin male and female which look like:

O O O O C (DB25 shell)

That one's a 5W5.

ITT designed these beasties to be very versatile. The large
openings can accept either power or coaxial contacts. They do come in
both solder-cup and crimp styles, however you should also be aware that
the contacts in the solder-cup types are not removable.

You should also know that, where the crimp style are concerned,
there is a significant one-shot investment required for the appropriate
hand tools for crimping and removal. Since these are mil-spec parts, the
tooling needs to meet that spec as well, so you're looking at $250-$300.

I can also supply the tooling, as can the dealers I've previously
mentioned.

Happy hunting. Drop me a line with specifics if you decide you
want a quote.

These are close but not quite the same.

But, I searched Newark and found the Amphenol connectors that are the same.

Thanks.

Thanks. Newark has them (actually the Amphenol connectors which are the
exact match). If you can match their prices on qty. 2-5 of each of these,
I go with you.

I don't know that I can match Newark (they've got buying power I
can only dream of), but I'll give it a shot. My local wholesaler is
quite good with the D-subs.

Hold that thought. I'll let you know on Monday.

Keep the peace(es).
