Does anyone know the name of this electical connector?

Here's a link to a Radio Shack one that is similar:

Here's some from Parts Express. Personally I would go with a metal one instead of plastic. RS has them too.

I agree about the metal being better, but all he wanted was the name of the connector so I pointed him to the first one I found.

I think you are correct, I compared it to a regular 1/8" headphone jack, and it appears to be same size/shape (expect I'd need mono). I really need the "female" end of it to connect to a battery. I was hoping to find a ready made female input with two heavy duty leads ready to connect. I saw that Radio Shack does have some parts I can solder together myself, if needed.

Looks like a typical 1/4in male mono jack like I use for my Peavey speakers

They come in right angle versions

😉

Sorry, that wasn't directed towards you. It was meant to be a general statement.

You can probably find it in Amazon also.

try Mouser electronics in texas. good website, and sizing etc. pdf's are attached to every item

looks like 1/8" mono to me.

It looks like a 1/8" (3.5 mm) phone plug but don't overlook the fact that there is also a 3/32" (2.5 mm) phone plug.

I've soldered up a lot of these over the years.

Ditto the metal ones over the plastic ones - they'll take a beating.

You have to "mic" the plug to see the diameter; I can't estimate it.

They're not rare, and I like Mouser as a supplier.
