There seems to be 10 million different types of connectors available. Radio Shack just has the gigantic sized power plugs. Where can I get the header and female plug for PC fans? 3-pin or 4-pin. Does anyone know the official name so that I could search for it?
That is a Molex KK receptacle... or in generic terms, a polarized 0.100 pitch connector.
I buy mine from www.futurlec.com - they're a lot less expensive than anywhere else I have seen. However, you can get genuine Molex branded connectors from any supply house.
the plastic connector is the cheap part, what makes it expensive, is the darned metal pins that go inside it ... they cost a fortune compared to the housing.
in regards to the pins, you can crimp them using needle nose pliers, but if you're going to be making more than a few, invest in the proper tool, otherwise your fingers will fall off. I recommend the Paladin Crimp-All aka the Paladin 8000 - it really makes the assembly easy ... and the paladin is a multipurpose tool, buying additional dies, you can crimp anything from RJ-11 and RJ-45 telco connectors, ring terminals, and different sized coax connectors.
hehe, mouser's website is awful - use their catalog if you like to purchase from Mouser
Molex KK is a BIG family, you have polarized, non polarized, friction lock, locking tab, and then different numbers of circuits, rows, current ratings, coating types, the list goes on
the easy way would be buying from reseller that offers a small selection (like futurlec or jameco), or getting a print catalog, so you can see the specs for the different model numbers in the KK family.
alternately, you can visit the Molex website, which has a handy search by picture feature, to identify the exact part you need.
60 cents for each crimp pin! That's crazy. You can but a computer fan, with 3 crimp pins, a connector, 4 LEDs, and of course a bushless motor and fan for $2.

It might be 0.100" pitch; his drawing does not specify. While the 0.1" is the most common, I've seen a bigger style on the parts shelf at Fry's.
The pic shows both polarized, and a locking tab. But the pic's funny. The female plug pictured should have thin square polarization tabs on its corners, whereas the pic shows one away from its corner.
those aren't molex type KK ... I do not doubt they are for some sort of molex connector... they actually look like a wire to board type pin... you crimp a wire in, insert the pin into its housing, and the pointy tip goes through the pcb, and you solder it.
at a 100 for a buck, they're waaay too cheap to be type KK pins, even the chinese molex-clone imports on ebay aren't that cheap!
I've got a roll of the KK pins in my shop, I'll take a close-up picture of it a bit later
