Help! Connector ( Plug and Receptacle ), 3 Pin, >= 20A Needed for Audio Power Supply.

Help! Connector ( Plug and Receptacle ), 3 Pin, >= 20A Needed for Audio Power Supply.

I have been trying to find an audio power supply connector with 3 ( or more ) pins, which is an industry standard. However, looks like, such standard is not available. There are standard DC connectors, usually, used in wall adapter power supplies for single voltage power supplies ( positive and ground ), but, I have not been able to find a standard three pin connectors for positive, negative and ground and for AC ( before and after a transformer ).

So, the ideal connector is :

1. AC and DC rated.
2. >= 20A.
3. >= 35V.
4. Metal, possibly, Aluminium or Copper. Plastic in case metal is not available.
5. Screw cap.
6. Panel mount receptacle with thread.
7. Female pins on the receptacle.
8. Plug with a threaded cap.
9. Male pins on the plug.

In case there is not such, which one is as close as possible?

I have had a look at some Lex connectors, TE Connectivity connectors and high current banana plugs. I am not sure whether there are any with this description.

Chinese OK, although, not preferable. Made in China by big non Chinese companies preferable.

Please, help! In case you have used any plugs and sockets >= 20A, please, inform.
 
I found some popular terms to determine what I look for :

A single, 3 pin with earth lead, circular, threaded, metallic, circular connector, a. k. a. Aviation Connector :

Socket ( receptacle ) : PXM7012 03S ST by Bulgin
Blocked

Plug : PXM7010 03P ST 1315 SN by Bulgin ( abbreviated to PXM7010 03P ST )
Blocked

The problem is the socket costs $42.43, the plug costs $74.33, thus, the two of them cost $116.76. I need three couples, which cost $350.28! I can, probably, purchase the whole airplane for a lower amount of money.

Do you know anything normally priced?

Again : what do you use?

But 30A DC current distribution even at low voltage is very dangerous with high fire risk and protection gear (ie switches, breakers, fuses) are very large and very expensive. Much safer and more cost effective to have multiple smaller power supplies.

The Neutrik connectors are excellent but I would always be concerned of a mains rated connector being used for lower voltages and non ac circuits. Amphenol ecomates were always good quality and came in an array of sizes with screw connections. Worth a look,.

Thanks! These are wonderful! However, the site does not give prices, but, there are many other GX25 connectors on elecbee.
