ANSI/IEEE coaxial connector symbol
IEEE-oriented coaxial connector symbol showing mating centre and outer contacts for a coaxial cable.
In plain English
What does ANSI/IEEE coaxial connector mean?
IEEE-style schematics show a coaxial connector as a centre contact within an outer shell outline, often with the shell tied to ground. US-practice drawings label coaxial jacks with J reference designators and plugs with P, following IEEE reference designation practice.
A simple example
This is an independently drawn explanation, not the IEEE graphic. Connector series and impedance must still be given. Where the shell is grounded at the panel, the outer conductor of the cable is grounded there too, which affects ground loop analysis.
What the drawings help you do
Read J or P designations to identify jack or plug. Check shell grounding at the panel. An ANSI coaxial connector mates concentric contacts; the ANSI plug and socket pair mates single conductors.

How to read it
- Read J or P designations to identify jack or plug.
- Check shell grounding at the panel.
Information to show or reference
- State connector series and impedance.
- Use J and P designators consistently.
- Show shell grounding.
A distinction that matters
An ANSI coaxial connector mates concentric contacts; the ANSI plug and socket pair mates single conductors.
