Abstract:
1. A carriage chassis for installation of a component assembly in a support structure, the support structure comprising a power connector in a connector housing, the power connector adapted to couple to a component assembly installed in the carriage chassis, the carriage chassis comprising: a plurality of rails adapted to receive a component assembly and adapted to receive a safety cover, wherein at least one of the rails comprises a tri-lobed torsion stop, the tri-lobed torsion stop comprising: a first lobe configured to contact the connector housing when no safety cover is installed in the carriage chassis, thereby preventing a component assembly installed in the carriage chassis from coupling with the power connector; a second lobe configured to receive contact from a displacement member of a safety cover upon installation of the safety cover in the carriage chassis, thereby rotating the tri-lobed torsion stop; and a third lobe configured to provide contact to the displacement member of the safety cover when the safety cover is installed in the carriage chassis and a component assembly installed in the carriage chassis is coupled with the power connector, wherein: the first lobe configured, when the safety cover is installed in the carriage chassis and a component assembly installed in the carriage chassis is coupled with the power connector, for insertion into a connector housing receptacle adapted to prevent rotation of the tri-lobed torsion stop; and the third lobe and the first lobe prevent removal of the safety cover when the safety cover is installed in the carriage chassis and a component assembly installed in the carriage chassis is coupled with the power connector.
