Maybe, but perhaps it works for those items because they don't have (at least,I haven't seen) any chassis-mounted 'plugs' - as I said, the concept of a 'fixed' (chassis-/panel-mounted) 'plug' would seem very odd (at least, to me) - since 'a plug' is something that one 'plugs into' something else.The automative and towing communities have no problems, Try googling for images of trailer plug, then trailer socket.
Quite so!Also IEC plug, then IEC socket. There are wide selections of names including, but probably not limited to: inlet, outlet, male, female, plug, socket
