can anyone help me with the name of these power plugs please?

I have purchased a linear power supply for my project tube box s, now I need to find the correct plug both ends.

Finding it hard to find as I don't know the correct name for them.

Thanks.

It's not just the name, but the various diameters.

I replaced one on my Netbook Charger and it was hard work ploughing through all the options.

I would call the DC power plugs, although there absolutely no reason they cannot carry AC - as the PSU for my satellite meter in fact does. The correct name is a cylindrical connector.

DC connector - Wikipedia

The important dimensions are the inside diameter, outside diameter and length of the plug.

Sorry, Chris: "DC Power Male Jack Connector" is the generic name used by most suppliers.

Looks like yours is either the third or the fourth plug from the left

It's 5mm wide and 10mm long, I can only guess at the hole centre diameter, both ends need a different diameter centre.

Might have to take a walk around somewhere like maplins.

1.2Mtr Polar MTG yes it has been on the arc for 25 years and is now fixed on 13 East using two pairs of rusty molegrips. Unlike me they never groan but always perform.

Oh yes I have one of those variable voltage transformers with multiple option terminations, you can arrange them for +centre or -ve centre by rotating the connector into the socket and the transformer was adjustable from 1 to 15 v, really useful piece of kit i used to keep in my van. It was great as I could usually get whatever kit that was involved up and running and then return when the correct spare was either located in my limited stores or purchased from a supplier, indeed I still have it somewhere, I think.

Somewhere in England (possibly?)!
Simple question: what is the voltage and current of the tube box s that you want to power, because that will mainly determine the type of plug on the end of the supply lead (which is normally attached to the actual PSU)?
NB: I think there is probably an IEC standard which gives the standard voltage/current/plug combinations!
Also, look at the rating label and tell us whether it shows the +V connection is to the centre pin or the outside of the connector of the box power inlet.

Tell us that and I/we can probably tell what you need to look for?;)

Managed to sort a lead out using some plugs from maplins.

The power supply is faulty the dc output has nothing just the ac output :(

The tube box s takes 18v dc 1.0 amp.

Then on ebay you can find a range of suitable PSUs, e.g. 18v 1.0 in Computers, Tablets and Networking | eBay.

PS: many laptops use a 19V o/p PSU, and that should be fine - the voltage difference is negligible!

PS2: and, Yes, I know you have found a suitable connector!

I have the linear supply already, I just needed to make the cable up for it, just waiting for the eBay seller to get back to me.
