Low voltage plug

The male part of this plug is bad, it is for an inside LED decorative tree. I have searched the web looking for a replacement and not finding anything.

Anyone know the name or where to look?

It is for a 120V to 24V ac wall wart.

Since it is low voltage I would just bypass the plug (cut it off) and direct wire it to the wall wart. Or get a new 24 volt wall wart with wire leads and splice the tree wires to them.

Thanks for the response, greatly appreciated. I'm confused on this, I would have no issue direct wiring it, but the wall wart is one piece and I see no way to open it or attach wires to it, other than a plug?

Then you may need a new wall wart. Me, I'd probably cut the prongs off the plug and solder them to the wires then just push them into the power supply. I might even carefully "disassemble" the plug with a hammer to get better access to the prongs.

That's called a DIN speaker plug. Used on mostly European audio equipment sold here.
I left you a search page. You may be able to find a US based retailer.

AH HA! DIN speaker plug. Just what I needed. Found them on Ebay mostly from Europe, Australia Hong Kong. About $5 ea with shipping.

There is an electronics place in Orlando that has bins of odd and surplus stuff, I have been waiting for an excuse to go to Orlando to see if they had anything.

I will give disassembling the old plug and soldering before I order a try. Not sure if I should use a framing hammer, ball peen or a stonemasons may be the right tool for this job

Thanks for the input greatly appreciated. Jim

Maybe you have noticed that electrical/electronics are not my strong point. I managed to get the plug apart for soldering but there is no way to identify which wire is + or- in the plug.

The wart itself is not polarized, both prongs are the same size, not a large and small one, going into the 120 receptical. So I would guess that polarity is not important? Yes no??

Not even sure I am asking the question right? Jim

If it is AC it doesn't matter. Test the wall wart with an analog multimeter set to DC. Positive probe to one slot. Negative probe to the other. If the needle tries to go backward you have the positive probe in the wrong slot. Not sure how a digital indicates reverse polarity but you could test a battery to see.

A digital meter puts a - before the value.
