Guys

(Apologies if this is a double post)

I'm trying to find information on the American Aerospace practice of naming Interface connections using J notation, ie, connectors called J1, J2 etc.

Is there a military standard, or industry wide practice that states how this should be done, or is it just a irregulated standard thing that everyone follows blindly????

If so, where can i find such a document, and is it available online?

Cheers, and thanks in advance.

Never thought much of it...I've been using J (I always assumed it was for 'jumper') since grade school on my schematics.

I've always assumed it was "J" for jack and P for plug. Our equipment is always layed out with the J on the circuit board and the P on the wire bundle.
When we have two plugs connecting they are tagged PPF and PPM. I've assumed again for Plastic Plug Male and Plastic Plug Female.
I couldn't locate a document designating this, it's just what everyone has always done.

I don't know the answer either but the conventions must go back aways. Naming IC's "U" for "Micro Circuit" (uA = Opamp) and CR for Diodes (Crystal Rectifier) ages things.

Small aside — "crystal rectifier" at one time nay have been a lucid description, appropriately differentiating the devices from {initially more prevalent} vacuum diodes of selenium rectifiers.
