I am looking for a way to make certain components (such as pots &
trimmers, 1/4" phono jacks, switches, or other sub-circuits) "plug and
play" for various prototypes + experiments. Similar to the breadboard
concept but more permanent. Headers like those found on computer
motherboards for connecting power LEDs are small enough where the
leads match the components I'm using and the pins on the motherboard
are just the right size to plug into a solderless breadboard, but are
more durable than breadboard jumper wires.

Rick suggested "daisy chain jumper wire" (see below for a description)
and I did some searching on various sites, but no luck. Can anyone say
what else this might be listed under or where it might be found?

Thanks...

I think you might be looking for something that was called "daisy
chain
jumper wire" way back in my wire-wrap days. It came as a spool of
flexible, stranded insulated wire about 24 guage or so, with an
insulated single pin socket every 5 inches or so. You just counted
off
the number of jumpers you wanted to interconnect, and snip them off of
the roll. The sockets fit over standard .025" square posts quite
nicely
and allowed testing minor modifications without wrapping on new wires.

They had a multitude of uses. I still have some leds and other things
with single 5" wires attached to each leg (each with it's own socket
at
the end).

I haven't even looked for this stuff for years, and know I hava a half
roll tucked away in a box somewhere. If I could only find it I'd at
least have a part number and manufacturer to provide. I'll see if I
can
dig it out sometime in the next couple of days...

Good Luck

Thanks to everyone for your replies.

There are literally hundreds to choose from, but here are a couple
example part numbers I pulled out of the Mouser catalog to point you in
the right direction:
Header: Mouser 517-2312-6111tg, 3m 2312-6111tg
Socket: Mouser 517-974-01-02, 3m 929974-01-02 (board mount)
the sockets also come for crimp pin or IDC connections.

That should be a big help - I just needed some keywords: header,
socket, board mount, IDC.

From: kony
Male pin headers and female socket connectors with 0.1" pin
spacing. Also socket contacts (inserts) are often sold
separate from the socket itself.

This helps...

What exactly are you looking for? Straight plastic sockets
with 0.1" pin spacing but do they have to be the very thin
(black in your links) type such that on a row of pins in a
pin header, you could plug in two right next to each other,
OR could the plastic connector body be larger like those
used on fans? The point is that if looking for an
especially low price, one option is surplus electronics
'sites which may have something that would work (or may not)
depending on the requirements beyond the basic # of pins,
spacing and pin size.

This would be a way to make certain components (such as pots &
trimmers, 1/4" phono jacks, switches, or other sub-circuits) "plug and
play" for various prototypes + experiments. The motherboard size
headers are small enough where the leads match the components I'm
using and the pins on a motherboard that LEDs plug into are just the
right size to plug into a solderless breadboard, but are more durable
than the regular breadboard jumper wires.

You might check the following surplus sites (and ebay).

Thanks again

I tried searching for LED connectors and get LEDs. I want the
connectors and posts, not replacement LEDs for a motherboard.

Ah, yes, the connectors are general-purpose, and have nothing to do
with
LEDs specifically, although this is the context in which you happen to
have encountered them; therefore searching on the term "LED" is
leading
you astray.

There are literally hundreds to choose from, but here are a couple
example part numbers I pulled out of the Mouser catalog to point you
in
the right direction:

Header: Mouser 517-2312-6111tg, 3m 2312-6111tg
Socket: Mouser 517-974-01-02, 3m 929974-01-02 (board mount)

the sockets also come for crimp pin or IDC connections. I think once
you stop searching for "LED" you'll be able to find things easily.

Male pin headers and female socket connectors with 0.1" pin
spacing. Also socket contacts (inserts) are often sold
separate from the socket itself.

They can be very expensive from electronics supply houses,
ridiculously so for the female connector and insert.

You might find them called something else, generically
grouped as just "connectors" or slightly more like "pin
connectors" at a store/site that doesn't deal with as many
connectors and just doesn't follow standard naming
practices.

From his earlier question I think the sockets are important. I think he's
really after a 2 pin socket (0.1" pitch) ready crimped onto leads. Perhaps
double ended to connect a panel mounted LED to a 2P 0.1" pitch PCB mounted
header? Not sure why he doesn't make them?

My preference was always a strip of 0.1" pitch turned pin socket pins
with ribbon cable soldered into the socket side. A little hot glue or
electrical grade silicone RTV sealent at the breadboard or PCB end and
judicious use of heatshrink at the component end provides strain releaf
if required.

Plug streight in to breadboards *WITHOUT* ruining the contacts, but
sufficently durable that the mods I did to my Sinclar QL nearly 20 years
ago using this connection methor are still totally reliable in operation.

As I remember, it was from one of those "if you have to ask the price,
you probably can't afford it" breadboard manufacturers. Augat, or Cambion,
or the like.

Dig, Dig, Dig. Ah, no. It was Berg (part of DuPont). In an old (1994)
Newark catalog I keep for reference, it's "Daisy Chain Jumpers", $215.72
for a chain of 250, either 2.5 or 5 inch spacing.

We used the same crimp terminals at a place I worked at in the '80s.
The hand crimp tool cost about $900. The contact is self contained and
doesn't need any plastic shell to make the contact spring action work.
So the terminals can fit into a shell (like we used them), or work by
themselves, insulated with shrink tubing.

But things aren't that bad, now. They use(/used?) very similar crimp
terminals in the header connectors for PCs, like the plug to hook the
reset button or speaker to the mother board.

Jameco sells this stuff as ".100" Non-Polarized Connector Housings and Crimp
Pins". IMHO, try part 100766. Page 155 in the May 2007 catalog. 12 cents
a terminal and the crimper is only $10.95. Add a little bit of wire and
shrink tube. What a difference 25 years makes...
