A connector assembly comprising: a connector housing having a connector body with a plurality of terminal cavities (18, 20, 22), a first slot, and a second slot, the plurality of terminal cavities (18, 20, 22) being configured to receive a plurality of terminals (94 96), the first slot extending longitudinally through the connector body, the second slot extending laterally through the connector body, the connector body including a first plurality of lock projections that are configured to engage a first edge of the plurality of terminals to retain the plurality of terminals in the plurality of terminal cavities; a lock reinforcement that is slidably received in the first slot for movement between a first position and a second position, the lock reinforcement engaging a subset of the lock projections when the lock reinforcement is in the second position to prevent deflection of the lock projections away from a first subset of the terminal cavities; a secondary lock that is slidably received in the second slot for movement between a third position and a fourth position, the secondary lock being configured to engage a second edge of a subset of the terminals when the secondary lock is in the fourth position, characterized in that the lock reinforcement includes a cam, that the secondary lock is configured to engage the second edge of a subset of the terminals when the secondary lock is in the fourth position to retain the terminals in a second subset of the terminal cavities, and that the secondary lock includes a cam follower that is engaged with the cam; wherein the cam and the cam follower cooperate when the lock reinforcement is moved in the first slot from the first position to the second position to move the secondary lock in the second slot from the third position to the fourth position. a connector housing having a connector body with a plurality of terminal cavities (18, 20, 22), a first slot, and a second slot, the plurality of terminal cavities (18, 20, 22) being configured to receive a plurality of terminals (94 96), the first slot extending longitudinally through the connector body, the second slot extending laterally through the connector body, the connector body including a first plurality of lock projections that are configured to engage a first edge of the plurality of terminals to retain the plurality of terminals in the plurality of terminal cavities; a lock reinforcement that is slidably received in the first slot for movement between a first position and a second position, the lock reinforcement engaging a subset of the lock projections when the lock reinforcement is in the second position to prevent deflection of the lock projections away from a first subset of the terminal cavities; a secondary lock that is slidably received in the second slot for movement between a third position and a fourth position, the secondary lock being configured to engage a second edge of a subset of the terminals when the secondary lock is in the fourth position, characterized in that the lock reinforcement includes a cam, that the secondary lock is configured to engage the second edge of a subset of the terminals when the secondary lock is in the fourth position to retain the terminals in a second subset of the terminal cavities, and that the secondary lock includes a cam follower that is engaged with the cam; wherein the cam and the cam follower cooperate when the lock reinforcement is moved in the first slot from the first position to the second position to move the secondary lock in the second slot from the third position to the fourth position.
