I'm looking for a standard male USA mains plug (NEMA 1-15 or 5-15) that I can attach directly into my enclosure. Here's roughly what I'm looking for:

But those are only available in bulk, it seems.

I've searched high and low from various suppliers, but can't find anything. It can mount into the chassis or direct to the PCB -- I don't care. Molex makes similar blades, but they're not the right thickness or length.

Honestly, it's almost to the point that I'm going to disassemble a random wall wart and make it work. And yet it feels like this should be an easy to find item!

I've attached my schematic for reference. Sorry for the occasionally unreadable text. The project is a power monitor to sound an alert if the GFCI circuit is tripped (killing power to my chest freezer). Comments and suggestions are appreciated.

 

Just one off or going into production?

For one off, the wall wart idea has worked for me.

 

For the other end, I use these with a 1" punch.

 

How about adapting a cord plug or an IEC entry?

 

One-off. Although I might make a couple of them eventually (which is why I'm avoiding the wall wart solution if possible).

 

I found it!!!!!!!!!

ps.
I'm ordering some of these.

It's bigger than I'd hoped, but looks about right. What's the source?

 

If you want to build the alarm, I understand. But you can buy one for less.

The modified plug would bolt in and take up less real estate. Skip the shell.

Lucky find, wouldn't have found them without a push.

Here's another type.

 

Never mind ... found it.

There's a D-Sub connector with a similar part number that was throwing off my search. Now to find a datasheet for the correct cutout size...

 

It could be snapped in and used to mount slotted circuit board.

 

1.05" square.

Most others I used are a little less than an inch and fit loosely in my 1" square punched hole.

These should be snug.

So, put in two slots to match the blades and solder together? Not a bad idea.

 

This company makes an enclosure with a plug built-in.

A bit better than reverse-engineering a wall wart, I suppose.

 

Will your circuit fit?

 

And another one ...

Fit will be tight, but should be possible, especially with surface mount and a two-sided board. The plug takes up a third the PCB, it seems, but the few high-voltage components can fit on that section, leaving plenty of room for the rest. I'll try to lay it out tonight and see.

Hey, did anyone found a professional (not adapting wall warts and stuff like that) way to do this for small-production?

I am interested in something similar to the Heyco link provided by boredcircuits user: http://www.heyco.com/Nylon_PVC_Hardware/product.cfm?product=PCB-Connectors but they sell in bulk and the minimum quantity to order is about tens of thousands. My production run is intended about a few dozens.

Yes. The solutions are in the thread.
