DEFINITION

Classification: 439/678

By asymmetric disposition or asymmetric shape of duplicate contacts:

(under subclass 677) Coupling part wherein all of the contact are identical; the identical contacts either (a) are randomly or irregularly disposed on the coupling part and are adapted to engage correspondingly disposed counter-contacts on the mating coupling part, so that the coupling part can be coupled to its mating coupling part at only one relative disposition of the coupling parts; or (b) have an irregular shape, the irregular shape of each contact enabling the contact to engage a complementarily-shaped counter-contact on a mating coupling part in only one relative disposition of the contact and its counter-contact, so that the coupling part can be coupled to its mating coupling part at only one relative disposition of the coupling parts.
