Help identify a connector
 

Can anyone help identify this electronics connector? This is on a medical
instrument (Topcon retinal camera, model TRC-50EX) from the 1990s:

I thought it was some custom item, but then I saw something similar to the
female side on a Motorola walkie-talkie recently.

I'm pretty sure it's similarity to other connectors isn't going to help
you here. That is most likely a custom connector, even if it is a
standardized style.

The connector is most likely custom. However, you can buy the spring
pins made by Mill-Max (and sold by Allied et al), and machine a housing
to hold the pins. The Mill-Max spring pins are actually intended for
Automatic Test Equipment fixtures. http://www.mill-max.com/

That's helpful, thanks. The pin side is actually the one I need to make.

I don't mean sorta similar. I mean it was the same connector with a
different number of rows of pins, like D-subs come in various pin counts.

If you want some pogo pins to play with, email me your mailing address
and I'll stick an assortment in an envelope. I must have a couple
thousand pulls from test fixtures. From the photo of the connector, it
looks like pins with a hemispherical head would be appropriate?

Ask on news:sci.electronics.design. There are some people there that
work in medical electronics design.

Like Ned says, it looks like they took standard pin contacts and
molded their own plastic block for them.

I've never seen anything like that mass-produced - and I know the
Motorola connectors you speak of, same idea. They want to drop the
radio into a ConvertaCom, have the radio body held in alignment with
the pin pad in the docking adapter, and have it mate up automagically
on insertion.

Doesn't ring a bell here. It almost looks like a custom order design.
The only ZIF connector type we used and occasionally still use is the
ITT/Cannon style with sideways-engaging contacts. Nowadays I try to stay
away from expensive specialty connectors.

Richard, if you absolutely need this style you could send the picture to
several large manufacturers such as Tyco.

Everett Charles makes this type of spring-loaded contact. Try this:
http://www.ectinfo.com/en/search/def...chterm=bip%2D1

The small rounded tip retracts into the body and the largest diameter
locates the array of contacts in the molded plastic housing. That
particular one is long enough to solder to a single-sided 0.062" thick
PC board. You might be able to retain it in unclad board with a
soldered loop of fine solid wire.

It connects to the SMBus on a Zoll defibrillator battery pack. I have
only assembled boards and can't measure the hole diameter, but
generally when I make prototypes I try for a light press fit in
unplated holes.

Yup, it looks very much like the accessory pins/connectors
for Motorola portable radios. Sometimes you could get the
individual pins from Motorola parts, sometimes they were
sold via assembly only. I used to steal them from bad
speaker mics and such to fix others. If you just want some
of the pins to play with try asking at your local Motorola
repair shop. If you are lucky and run into a pack rat like
myself, they may have a box full of cast-offs you could
have/pick through. The female or flat side was usually part
of the frame/housing.

It has been a few years now, but the Visar series used very
similar pins and the housing (on the accessory side) could
be disassembled most of the time. The best place to find the
part numbers for them (Motorola) was for the programming
cables. Of course several other portables had them too. If
you want to try this, take your parts along with you so a
side-by-side comparison can be done.

That's also the sort of connector that current Symbol Technology bar code
terminals use.
