Connector assembly, comprising: a first connector configured to mate with a second connector along a mating axis; a second connector; a primary locking lever pivotably mounted to the first connector; a beam defined by the primary locking lever and extending along the mating axis; a primary latch mounted to the beam, wherein a forward ege of the primary latch further defines a secondary striker; and a connector position assurance device movable from an initial position to a final position only when the first connector and the second connector are mated, said CPA device having, a mobile base slideably mounted to the first connector, and a CPA lever mounted to the mobile base defining a secondary latch, wherein the secondary latch engages said primary latch to inhibit movement of the CPA device from the initial position to the final position until after the first connector and the second connector are mated, said CPA lever defining a lateral flange configured to engage said beam, thereby maintaining engagement of the primary latch with the secondary latch until the first connector and the second connector are mated, wherein the second connector includes a primary striker configured to engage the primary latch so as to lock the first connector and the second connector together when the first connector and the second connector are mated, and wherein the secondary latch of the CPA device is configured to engage the secondary striker when the CPA device is in the final position so as to prevent disengagement of the primary latch from the primary striker, the CPA device being movable forward from the initial position to the final position whereby the secondary latch rides over the primary striker and the primary latch until it clears the primary latch and deflects back to its original orientation wherein the primary latch engages the secondary latch. a first connector configured to mate with a second connector along a mating axis; a second connector; a primary locking lever pivotably mounted to the first connector; a beam defined by the primary locking lever and extending along the mating axis; a primary latch mounted to the beam, wherein a forward ege of the primary latch further defines a secondary striker; and a connector position assurance device movable from an initial position to a final position only when the first connector and the second connector are mated, said CPA device having, a mobile base slideably mounted to the first connector, and a CPA lever mounted to the mobile base defining a secondary latch, wherein the secondary latch engages said primary latch to inhibit movement of the CPA device from the initial position to the final position until after the first connector and the second connector are mated, said CPA lever defining a lateral flange configured to engage said beam, thereby maintaining engagement of the primary latch with the secondary latch until the first connector and the second connector are mated, wherein the second connector includes a primary striker configured to engage the primary latch so as to lock the first connector and the second connector together when the first connector and the second connector are mated, and wherein the secondary latch of the CPA device is configured to engage the secondary striker when the CPA device is in the final position so as to prevent disengagement of the primary latch from the primary striker, the CPA device being movable forward from the initial position to the final position whereby the secondary latch rides over the primary striker and the primary latch until it clears the primary latch and deflects back to its original orientation wherein the primary latch engages the secondary latch.
