The invention includes first and second electrical connectors and a connector position assurance member that is lockable in a pre-staged position. A first connector includes a pivotally connected pump handle lock arm positioned to lock on to a nub on the second connector. A connector position assurance member (CPA) is constructed for slidable movement on the first connector and includes two forward reaching arms each having a stop on a lower edge that engage a shoulder positioned on the first connector when the CPA is in a pre-staged position. In this pre-staged position, a lock arm of the CPA grabs into the pump handle on the first connector. The stop, shoulder and lock arm prevent forward or backward slidable movement of the CPA from this locked pre-staged position. As the first and second connectors are mated, a ridge on the second connector engages an angled portion of the forward reaching arms causing the arms to be lifted to raise the stop above the shoulder on the first connector and allowing the connector position assurance member to be moved forward to a final assembled position. Locking nubs on the CPA and the first connector may be positioned to keep the CPA in the final assembled position.

[ We claim:] [1.] An electrical connector assembly comprising:a first connector having a plurality of cavities formed therein and a latch nub on a surface,a second connector having a plurality of cavities defined therein and a primary connector lock arm elevated above a surface of the second connector for pivotal movement of the lock arm, the lock arm being slotted and defined by two spaced apart fingers and a bridge connecting the fingers at a first end and a pump handle connecting the fingers at a second end, channels being defined in the second connector intersecting a raised shoulder formed in the second connector,a connector position assurance member having a base and two spaced apart steering arms extending in the same direction from the base and having a ramped tip and constructed and arranged so that a steering arm may be slidably moved in a respective channel formed in the second connector, said steering arms having a stop defined at a lower edge so that in a first pre-staged position of the connector position assurance member, the stop on the steering arms engages the raised shoulder formed in the second connector, said shoulder preventing further forward slidable movement of the connector position assurance member, and wherein upon mating said first connector to said second connector the bridge of the primary connector lock engages the latch nub on the first connector causing the primary connector lock arm to pivot upward and ride over the nub and snap back downward so that an inside edge of the bridge engages a rear surface of the latch nub locking said first and second connectors together and simultaneously a ridge on the first connector engages the ramped tip on each of the steering arms of the connector position assurance member causing the connector position assurance member arms to be lifted up wherein the stop at the lower edge of the arms is raised above the shoulder formed in the second connector so that the connector position assurance member may be moved forward to a final locking position wherein a portion of the connector position assurance member engages an underside of the pump handle and a surface of the second connector preventing the pump handle from being depressed downward and unlocking the bridge of the primary connector lock arm from the latch nub.
