A further pin of a connector already tagged elsewhere, drawn without repeating the connector body or tag.

## In plain English

### What does Additional connector pin mean?

On schematics a connector often has pins scattered across several circuits and sheets. The first pin carries the connector tag and body, and each additional pin is drawn with a lighter child symbol that refers back to it. This avoids drawing the same connector several times with conflicting tags.

### A simple example

Readers should treat every child pin as part of the parent connector, so separating the connector disconnects all of them. The child symbol does not repeat the connector type or rating, which must be read from the parent. Pin numbers on child symbols must still be unique within the connector.

### What the drawings help you do

Find the parent connector tag for each child pin. Remember all child pins separate when the connector is unplugged. An additional connector pin is a child of a tagged connector; a standalone plug and socket pair is a connector in its own right.

### This particular reference

A further pin of a connector already tagged elsewhere, drawn without repeating the connector body or tag. An additional connector pin is a child of a tagged connector; a standalone plug and socket pair is a connector in its own right.

### Terms

- Terminal: An identified point where a conductor connects.
- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Readers should treat every child pin as part of the parent connector, so separating the connector disconnects all of them. The child symbol does not repeat the connector type or rating, which must be read from the parent. Pin numbers on child symbols must still be unique within the connector.

## How to read it

- Find the parent connector tag for each child pin.
- Remember all child pins separate when the connector is unplugged.

## Information to show or reference

- Cross-reference child pins to the parent.
- Keep pin numbers unique.
- State connector data only on the parent.

## Important distinction

An additional connector pin is a child of a tagged connector; a standalone plug and socket pair is a connector in its own right.
