DEFINITION

Classification: 439/633

Having polarizing means:

(under subclass 630) Coupling part further having indexing or keying means formed thereon or attachable thereto, which indexing or keying means is intended to cooperate with complementary indexing or keying means on a mating counterpart, so that either (a) the various contacts of the coupling part must always be associated with the same corresponding counter-contacts on its counterpart whenever the coupling part is joined or coupled to its counterpart, or (b) the coupling part must be capable of being joined or coupled to only one specific, but to no other, counterpart among a plurality of counterparts which are all structurally identical except for some variation of the indexing or keying means thereon.
