Class Information
Number: 439/677
Name: Electrical connectors > With insulation other than conductor sheath > Plural-contact coupling part > Plural-contact coupling part comprises receptacle or plug > Polarized
Description: Coupling part 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 coupling part, so that either (a) the various contacts of the coupling part must always be associated with the same corresponding counter-contacts on the mating coupling part whenever the coupling part is coupled to its mating coupling part, or (b) the coupling part must be capable of being coupled to only one specific, but to no other, mating coupling part among a plurality of mating coupling parts which are all structurally identical except for some variation of the indexing or keying means thereon.
