Connector mystery

[Don Lancaster]

Picked up a bunch of AMP / TE Connectivity 12 pin headers, part number
102692-1

and data at http://www.te.com/catalog/products/en?q=102692-1/

For some reason, they call this a TWO PIECE HEADER. Yet I
only have one piece and that is the way they are shipped in
original factory packaging. And this is what the data sheet shows.

They claim that two piece connectors are more reliable, and the
connector seems to have a "side porch".

What is the second piece, and where and how is it used for what?

Is the slot for an upstanding mezzanine circuit board?

If by "upstanding" you mean normal to the PCB on which *your*
connector is mounted -- yes. Think of some of the voltage regulator
modules you encounter/ed in PC's...

Imagine a right-angle female headed soldered onto the edge of the
board that mates to this. The board slides into the "slot" so that
the right angle header "sockets" align with the pins in your header.
The "back side" of *your* "slot" supports the underside of the
mating board.

The slot doesn't do much direct supporting of a normal 1.5mm-ish thick
board- it's more than double that. It can accomodate a 1/8" thick
board if that's what you need.

Looks like it's mostly a guide, helping with the support provided by
the notches at the ends of the mating part mating with the pointed
posts in DL's eBay offerings. Either way you crank the board, it puts
the solder joints in tension, I think.

Connetors are such a can of worms- I had to find some old 1950s
gold-plated rack panel connectors (at an impressively outrageous
price) because some dufus designed them into an instrumentation
interconnect. Sigh.

Hi Spehro,

(I'd wish you a happy Tday but don't think that applies! :>)

The slot doesn't do much direct supporting of a normal 1.5mm-ish thick
board- it's more than double that. It can accomodate a 1/8" thick
board if that's what you need.

The slot is wider that the board because the mating "sockets"
don't sit *in* the same plane as the mating PCB! :>

Look at the dimensioned drawing for the part. Without even chasing down
a likely mate, its safe to assume that there is as much "shell" "below"
(wrt the dimensioned drawing) the bottom row of pins as "above" the
top row of pins. I.e., 0.085 below the bottom row, 0.100 between rows
and *assume* another 0.085 above the "top" row -- brings you to the
"surface" of the PCB that mates to this (assuming the right angle
female header mounts flush with that PCB surface).

0.085+0.100+0.085 = 0.270. I.e., 0.029 *above* the "bottom" of the
slot -- and 0.098 below the "top" of the slot.

If the mating female doesn't *hug* the board that it's mounted on,
some of that gets eaten up (0.015 on each side of the mating board
for "wiggle room"?)

I.e., like a voltage regulator module.

You can make a *career* out of picking connectors! :<

I've been searching for a certain "ZIF" connector with equally
bad (expensive) results.

(in my case, *no* "second step" mechanical latch to engage... imagine
a ZIP socket on a PROM programmer where you drop the UUT in -- AND
DO NOTHING MORE!)

Many thanks.

I found a bunch of the other connector halves (less part numbers) in our
infinite supply of unprocessed eBay stuff that sorely needs triage.
