what name are those plugs?

[Orc General]

What is the name of those plugs that you see at the end of most laptop power
supply? It looks like two round concentric
steel cylinder wrap around each other thereby forming the +voltage
and -voltage source for the laptop.

Where can you buy some blanks? I am looking to build a replacement laptop
power source, I have the right voltage/amp
but need the correct connector going into the laptop.

Generically "Coaxial DC power plugs".

2.1mm and 2.5mm are the most common not-mini sizes, but some laptops
use a non-standard size.

Tim.

These plugs are what we call 'highly standardized' - there are about a
dozen or so standards. Radio Shack has many of them.

Some call them "barrel connectors"

I've actually been to RS looking for one, and the drone actually had
a string of comparison connectors. (kind of like a very long charm
bracelet.) Take the laptop in, and start trying connectors until one fits.
Buy that one.

Cheers!

No, they don't. A "barrel connector" is one that you poke a wire into each
end and crimp them in. Also known as a "barrel splice", but I have seen
them called "barrel connectors", like at the hardware store.

And your absolute expertise derives from ....?

This is a big land, with many cultures. Tissue; Kleenex. What is a milkshake
in Indiana is a frappe in Massachusetts, where "regular" coffee has milk or
cream in it. There's soda and pop. Also sodapop. Travel some, Rich, and
learn.

No, they don't.

Obviously, some do:

"Barrel connector" is so generic that it has no useful meaning:
You will find as many definitions as there are tech diciplines:

I wouldn't call Rich's gizmo a "barrel connector" or a "barrel splice".
I'd call it a butt splice.

OK, three corrections in one post! Guess I can take three days off now.
;-)

(actually, I already knew about the butt splice; just had a minor
lapse of attention, aka brain fart. )

Thanks!
Rich

45 years' experience, thank you very much.

I liked JeffM's correction(s) better, but thanks.

Always happy to oblige. ( It's non-fattening. ;-) )
