  • Publication number: 20240162654
    Abstract: A connector assembly comprises a first connector, a locking lever rotatably attached to the first connector, and a second connector engageable with the first connector. The second connector defines a first guide protrusion extending from a surface thereof. In a closed position, the locking lever engages with the second connector and prevents the second connector from disengaging from the first connector. The first guide protrusion disconnects the locking lever from the first connector and biases the locking lever in an opening direction toward an open position.
