DEFINITION

Classification: 439/679

By having or receiving contacts of similar type which are unequal in size or shape:

(under subclass 677) Coupling part either (a) wherein at least one of the contacts carried by the coupling part has a size dimension or a cross-sectional shape different from all the other contacts and yet is still similar in general configuration and structure to the other contacts and still functions to engage its corresponding counter-contact in the same manner as the other contacts, so that the coupling part can be coupled to its mating coupling part at only one relative disposition of the coupling parts; or (b) wherein the body of the coupling part has openings through or into which counter-contacts correspondingly disposed on a mating

coupling part must be introduced in order to engage the contacts carried by the coupling part so as to complete the electrical coupling, at least one of the openings has a size dimension or a cross-sectional shape different from all the other openings in order to accommodate counter-contacts having complementary sizes or shapes, so that the coupling part can be coupled to its mating coupling part at only one relative disposition of the coupling parts.
