DEFINITION

Classification: 439/653

Combined with diverse type of coupling part:

(under subclass 650) Device wherein the single unitary structure, in addition to having embodied therein the receptacle adapted to be coupled to a plug having spaced fingerlike counter-contacts, also has embodied therein a plural-contact coupling part which is of a type different from the said receptacle.

(1) Note. Two coupling parts are considered to be "different" if a mating plural-contact counter-part designed for coupling with one of the coupling parts cannot be coupled with the other coupling part. Thus, two plural-contact receptacles having spaced prong-receiving contacts which differ in number, arrangement (i.e., relative spacing therebetween), cross-sectional shape, or size constitute

"different" types of receptacles if a plug having spaced pronglike contacts is capable of being coupled to one receptacle but not to the other.
