Class Information
Number: 439/680
Name: Electrical connectors > With insulation other than conductor sheath > Plural-contact coupling part > Plural-contact coupling part comprises receptacle or plug > Polarized > By key or guideway
Description: Coupling part either (a) having a groove or slot thereon disposed parallel to the axis along which the coupling part engages its mating coupling part, which groove or slot is intended to cooperate with a member carried by the mating coupling part by slidingly receiving the member within the groove or slot to fix the relative angular relationship of the coupling parts about the longitudinal engagement axis whenever they are coupled; or (b) having a member thereon adapted to cooperate with a groove or slot disposed on the mating coupling part parallel to the axis along which the coupling part engages its mating coupling part, which member is intended to ride in said groove or slot to fix the relative angular relationship of the coupling parts about the longitudinal engagement axis whenever they are coupled.
