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.
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?
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:
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.
