DEFINITION

Classification: 439/638

Two or more plural-contact coupling parts combined in one integral unit:

(under subclass 626) Device comprising a single unitary structure having two or more spaced but electrically connected plural-contact coupling parts embodied therein.

(1) Note. This and the indented subclasses may include, for example, a unitary device commonly known as a cube tap, duplex receptacle*, twin receptacle, or multiple receptacle, etc.; and also included herein is that type of unitary device often referred to as an adapter which has, for example, a plural-contact receptacle at one end and a plural-contact plug at the other end.
