I used to have an old aiwa separates HiFi system which used this type of connector to distribute the power between amplifier/tuner/cassette separates. anyone know what its called? there are 3 rectangular pins on it.

Do you mean the 8 pin DIN plug?



​thanks but its not the round DIN pin, it is a rectangular power connection, maybe it is a manufacturer specific design.

Can't see a rectangular on the ebay one - if it's 3 pin mains, is it an IEC? Like a computer power lead

3 pin IEC female is what you have I think. If not try SignalsUk. They have helped me out with a pickup head recently. Very knowledgeable.

Damn you Derek

if its similar they are like ribbon cables and they are specific to aiwa.

No idea what the connector is but the image of the back of this unit shows the socket for the plug. Not sure if you can legally replace this connector as it's 240V mains passthrough on a relay and not a 12v DC connection. Do you really want the control unit to turn the separates on and off ?

It would be easier posting an image of the lead you have than everyone guessing what your refering to.

It's a weird 240v power connector.

A few here need to stop and read what's been posted ppl - this is no IEC connector. It's some propriety thing which aiwa appears to have copied from an old skool two-pin phono.

It appears that other US variants were previously used so you could retrofit something. Of course if these are vintage and there is a value to how they are then it may not be the best option.

No idea why you're being marked down as it's an NEMA 240v mains socket. It's a weird connector to prevent people plugging their coffee makers into the Hifi so when the timer hits it turns on the music, heats your coffee and probably burns your house down.

I think the third/centre pin is probably to prevent you putting the plug in the wrong way round more than act as an earth.

It's not an audio connector. It's a mains 240v connector oO
AC outlets 240v max 400W.
Do not connect electric appliances other than components for this audio system

​Yeah. If you look in the ebay link you can see the plug to the side of the unit on the end of the power lead. Looks like a small UK plug type thing. I think aiwa must of supplied a cable with each unit to link them up, this was made specifically by them. I remember this is what I had with my hifi separates but If I remember they used the kettle type plugs to link up units. Was a long time ago. I think I would be inclined to remove and replace with a standard UK plug assuming each unit has a power lead? Be less hassle and safe as I doubt you will get any now although worth a try. Hope you find at sensible money.

Yeah, I think the tuner probably contains a timing circuit that would switch on the tape recorder at a certain time to record radio programmes. Gotta love mechanical buttons and switches, shame they're long gone now and everything is electronic. I assume all the device were double insulated so didn't require a separate earth. Hence the double square logo in the picture.

Are you sure you're not trying to help natural selection ?

Right now I understand what your refering to.If you still wanting to connect the units you might be better of soldering a mains cable internally and routing it through the case with a rubber grommet for protection then fitting a standard 13 amp plug to the end.The plastic centre pin is just to ensure correct polatity of the cable to each unit.

Alternatly install a cable for each outlet with a quick disconnect [female end to the mains side] kettle lead
