Connector assembly having improved keying and latching system

摘要

An electrical connector assembly comprises receptacle housing and plug housing. The receptacle housing has a latch arm hinged to one sidewall thereof. The latch arm extends forwardly beyond the mating face of the receptacle. Keyways are provided on the sidewall beneath the latch arm and are covered by the latch arm. Inspection slots are provided in the latch arm in alignment with the keyways. The plug part has removable keys integral therewith which are received in the keyways. The parts can be keyed to each other by removing one of the keys from the plug and placing a key plug in the corresponding keyway. The latching and keying features occupy a minimum amount of space on the connector housings.
