UK NATO Jackplug
 

Can anyone tell me what colour spot by each wire inside the jackplug corresponds to please?

I have seen that but it doesn't help as I can't work out which wire goes to which ring. There is a different colour dot by each wire so I was hoping someone would be able to tell me which colour dot goes to which ring???

You're welcome.

Apologies Adam, Im sure I started that post with thanx.

Amazing. Is there no pearl of wisdom that cannot be found on PPRuNe, Mil Aircrew?

O ye of little faith

No, no. I have every faith. There clearly is no pearl that cannot be found here! Good diagram.

I'm surprised there isn't a standard connector by now. See image below of a Mk4A helmet. When introducing this, I wanted to use a 9 (I think) pin "snatch" connector, used by US Apaches. This met the UK spec for pull weight on emergency egress, which is about 8lbs.

I was told "No" in no uncertain terms by OR so had to go for what you see. They are staggered so one pulls before the other, to meet the 8lb limit. Also, you can perhaps see each is a different diameter, so you cannot mix them up in the dark, and the smaller one has a different sleeve length (the bit furthest from the tip). This was to avoid shorting as you could get this one in the others female socket, but not vice versa. Hope that makes sense.

I seem to recall the UK NATO connector design dates from about 1947, and originals remain in service!

Pre NATO ... Now that's what I call a plug :ok:

Oi! 'Oo are you calling a jackplug?

So it's a case of socket and see?

I'll get my coat...

As a technical friend of mine is wont to say 'The trouble with standards is there are so many to choose from.'

Standard Plug and Socket ... You need the good old Gosport Tube :eek:

Thanx 4 the diagram, that's what I was looking for.
Probably won't work but I'm going to wire the modern jackplug into a socket that that huge plug on the C-Type has to see if it works.

Or you could just buy

Aviation pilot headset adaptors

None of the available ones are for the bigger jackplug fitted to the C-type

Hi Alexis

your usual problem is impedances, particularly the mic. Really old headsets have carbon mic.s; an electret mic prends to be a carbom mic in a sort of way, and adjusting mic gain can often give a usable result.

Later 'massive' jack plugs (see Coffman stater's post) use the same colour code as my diagram.

I helped to modify a C type for the BoB 70th anniversary airfield tour, but used a modern headset from a MK.10C / Alpha type helmet. The transducers were a pain but the rest was simples.:ok:

For those who can genuinely breath through their ears?

The ladies will be pleased.

JTO :D:D:D:D

Coffman,

The plug in your picture with the helmet and goggles, will fit perfectly into a 359 socket!

Anyone know the type of wire that is used? What I had has disintegrated :ugh:

Not certain for sure ... but I think it was a cotton/copper mix that was highly flexible but impossible to solder. I think you will find that terminations were "whipped" ... But a Squipper will best to help :ok:

Sorry I should've mentioned the wire is connected to the modern jackplug. I got told to avoid using the original jackplug wire just for your reasons.

The copper-cotton wire is called Tinsel and the way I was taught to solder it during Air Comms Trade Training years ago was to take some finer single-strand tinned copper wire and gently wind it around the exposed conductor-cotton in a whipping fashion. Apply a tinned soldering iron to the whipping, wait until the insulating laquer 'burnt off' and apply fresh solder containing flux, covering the whipping. Remove from heat and cool. Cut off any whipping loose ends et voilà!
