I am currently drawing the circuit diagram for a device. To simplify the diagram I already using the ground symbol for all pins which are connected to ground. This makes the diagram much more readable.

But now there is a special power source (USB LiIon charger/power source) in the schema. It has various outputs, so I am currently draw all connections from the 5V output to the different components.

If I would use the symbol for VCC, it would simplify the diagram. But...

How do I show that the 5V output of the power source provides the power for all elements connected to the VCC (symbol)?

See this minimal example diagram:

  • \$\begingroup\$ @IgnacioVazquez-Abrams Technically I fully understand the concept of the named nets. It is more about the circuit diagram. Do I just draw the VCC symbol and connect the 5V pin to the VCC symbol? Does this make sense? \$\endgroup\$ – Flovdis Aug 21 '15 at 22:45

Just connect the source to a Vcc symbol. Make sure the name is exactly the same.

Here's a simple example from this webpage where the source is a USB connector and it goes to a chip and another connector.
