IEEE Standard for Connector designation in Schematics?

IEEE Standard for Connector designation in Schematics?

IEEE Standard for Connector designation in Schematics?

(OP)

First off, thanks for any help.

We have an issue in my office as to what is IEEE-standard for Connector designation in a schematic.  This has to do with 'P' vs 'J'.  Can anyone point me to an IEEE standard that proves out one of these two?

CAMP ONE
Standard for P and J designations is that P connectors are the portable connection or the moving connection - thus P's end up on cables. A 'J' connector is less mobile or fixed and ends up on the box or panel in most cases. It is possible to have a P-P connection in a cable to cable configuration.

CAMP TWO
The J (jack) defining the (s)ocket or "female" connector and the P (plug) defining the (p)in or "male" connector.

Thanks,

jMack

I can't, we use them both interchangeably.lol

OK, I found the standard.

ANSI Y32.16-1975     IEEE Std 200-1975
page 11

Quote:
4.1.5.3 Connectors.  Connector reference designations shall be assigned in accordance with the following principles:
  (1) The movable (less fixed) connector of a mating pair shall be designated P.......
  (2)  The stationary (more fixed) connector of a mating pair shall be designated J or X. .....

Thanks anyway!

Thanks for that post jmack5.  I was always part of Camp 2.

So my question is about a schematic of several harnesses that are not using bulkhead connectors, but still need to be designated.  What would they be identified as?

Nevermind, I missed that part about P-P connections.

"Designation: 200-1975

Reaffirmation status and year: 1988

Title: IEEE Standard Reference Designations for Electrical and Electronics Parts and Equipments

Status: Withdrawn Standard. Withdrawn Date: Jan 17, 1997. No longer endorsed by the IEEE."


From IEEE 315:

P disconnecting device (plug
connector)
electrical plug connector
plug (connector, movable portion)
waveguide flange (plain)

J disconnecting device (receptacle
connector)
electrical receptacle
connector
jack
receptacle (connector, stationary
portion)
waveguide flange (choke)

Good! I shall forthwith conform! Thanks guys. Must remember, must remember.. plug...

OK, I'm a bit confused.

Which one should I follow then?
IEEE Std 200-1975 or IEEE Std 315-1975?


Please explain to someone new with drawing standards...

RE: IEEE Standard for Connector designation in Schematics?

Well if 200-1975 has been 'Withdrawn'  why would you want to continue using it??

RE: IEEE Standard for Connector designation in Schematics?

I may be missing something here, but aren't both references saying essentially the same thing?  The moveable (or portable) connector is the P, and the fixed connector is the J?  As both standards were penned in 1975, it makes sense they both agree.  What standard replace 200-1975?

Thanks,
Mark

RE: IEEE Standard for Connector designation in Schematics?

They don't agree. 315 speaks of the movable plug and the stationary receptacle but doesn't speak to the stationary plug, or the movable receptacle. Male/female is avoided, but by most definitions the plug goes within the receptacle. The symbols of 315 also show the plug arrow going into the receptacle arrow pointing the same way.
