DEFINITION

Classification: 439/654

Having receptacle at each of parallel opposed surfaces or sides:

(under subclass 650) Device wherein the single unitary structure has embodied therein at least two receptacles adapted to be coupled to a complementary plug having extending therefrom at least two spaced, elongated, fingerlike counter-contacts whose longitudinal axes are parallel to the longitudinal axis along which the one coupling part is intended to be pushed toward and thereby into engagement with the other, and wherein at least two receptacles are located on the single unitary structure so that they receive their respective complementary plugs from directions opposite to one another.

(1) Note. Often the longitudinal engagement axes of the respective, oppositely directed receptacles are also aligned.
