Identification Standard Of PCB Terminal

This standard applies to the identification and identification of the terminals of equipment (such as varistors, circuit breakers, automotive relays, AC contactors, transformers, rotating electrical machines, etc.) and combinations of such equipment, as well as the identification of special transmission lines.

When necessary, the detailed use of such detailed rules for some commodities and the necessary auxiliary identification methods for PCB terminal manufacturers can be obtained in the relevant standards. For cold-pressed terminals, one or more of the following methods can be used to identify equipment terminals and special transmission line ends.

1. Use the identification system software of related products to clarify and identify the relative positions of equipment wiring terminals or special power line ends or cold-pressed wiring terminals.

2. Use the identification system software of the related products to clarify and identify the color identification of the terminal of the equipment and the end of the special transmission line.

3. Select the symbol picture required in GB5465. If the PCB terminal manufacturer chooses the auxiliary mark, it should be consistent with the drawing in GB4728.

4. Use the English alphanumeric symbols required in Chapter 5 of this standard.
