56 of the respective power terminal 28 power wires 18 with power terminals 28 terminated thereto are inserted into terminal receiving passages 24 of housing portions 24 in the direction of arrows u201c a u201d fig6 during insertion head portions 56 of the power terminals engage chamfered front ends 62 a of locking arms 62 to spread the flexible locking arms outwardly until head portions 56 engage shoulders 58 of the housing portions in this fully inserted or seated positions of the power terminals flexible locking arms 62 snap back inwardly into locking positions as shown clearly in fig6 still referring to fig5 and 6 when the two hermaphroditic housing portions 24 are assembled or interconnected locking projections 36 fig4 of each housing portion enter openings 34 of the other housing portion when the housing portions are fully interconnected locking projections 36 move into positions behind flexible locking arms 62 as seen in fig6 therefore the flexible locking arms cannot flex outwardly out of engagement with head portions 56 of power terminals 28 consequently locking projections 36 positively lock the terminals within the housing portions in addition should one of the power terminals 28 not be fully seated against the respective shoulder 58 of the housing portion locking arms 62 will remain biased to outwardly spread positions as a result locking projections 56 cannot be moved completely into openings 34 because locking arms 62 will.
