Role terminology
These words describe physical roles in the existing records. They are not interchangeable labels, and a mating-role description does not establish voltage, signal, protocol or safe substitution.
Plug usually names a mating component inserted into a counterpart. Receptacle and jack generally name receiving interfaces. Appliance inlet is used by IEC appliance-coupler records for the equipment-side member. Cord connector names the cable-side member in those pairings. The exact canonical record controls the terminology used here.

These tables reorganize facts already present in the canonical field notes and engineering sidecars. A shared count, role word, coupling method, alias or family label does not prove that two parts mate, carry the same signal, use the same wiring or are safe substitutes.
