TWIST-TYPE ELECTRICAL CONNECTOR WITH SAFETY INTERLOCK

摘要

TWIST-TYPE ELECTRICAL CONNECTOR WITH SAFETY INTERLOCK The present invention relates to a twist-type electrical connector having an improved interlock. In the connector, a plug and a receptacle are rotated angularly relative to each other to bring electrical contacts into engagement and to prevent accidental separation of the plug and receptacle. Entrance slots in the receptacle receive the male blades and carry detents which engage with a rear edge of at least one of the male blades and hold the blade in its seated or rotated position. The detents also provide an indication as to when proper connections have been established and also, prevent accidental counterrotation of the contacts.
