Lever-type electrical connector with connector positioning assurance member

An electrical connector assembly having a plug connector, said electrical connector assembly comprising:

• a connector housing having a flexible leg with a primary locking device configured to provide a primary locking function when the plug connector is mated with a corresponding counter connector, wherein the primary locking function can be disengaged when said flexible leg is flexed;
• and
• a secondary locking device being arranged movable relative to the connector housing between an open position and a closed position, said secondary locking device having a flexible arm and a jamming portion,
• wherein the flexible leg of the connector housing and the flexible arm of the secondary locking device are configured to be in blocking contact when said flexible arm is not flexed, so as to inhibit movement of the secondary locking device from the open position into the closed position,
• wherein the flexible arm of the secondary locking device is configured to be flexed when the plug connector is mated with the corresponding counter connector such that the secondary locking device can be moved into the closed position, and
• wherein the jamming portion of the secondary locking device is configured to prevent flexing of said flexible leg when the secondary locking device is in the closed position.
