Indeed. For some reason, they all got to be called 'DB', perhaps because the 25-contact size shell was so widely used. And before the high-density range was introduced, the pin-count and shell-size were 1-to -1 matched.

Oops; I actually lied. The SHELL size is indicated by the character after the D; turns out that there are multiple pin densities that can be fitted to each shell size.

D-submini connectors use the character after the "D" to indicate pin count:

DA=15-contact
DB=25-contact
DC=37-contact
DD=50-contact
DE=9-contact

Ah! I found it. I didn't expect the unpopular but correct DA prefix to be used.

Is there anywhere a symbol for the DB15 15-contact connector? I know that I could make one, but its geometry is not simple.
