Tiered locking mechanism for securing component cards to different height connectors for a main board

A component board comprising:

• a printed circuit board;
• and
• at least one tiered locking mechanism configured to secure a component card to the printed circuit board, the at least one tiered locking mechanism including:
• a base including a first-tier side wall at a component card engagement side of the at least one tiered locking mechanism and a coupling structure configured to engage the printed circuit board;
• a top slider structure coupled to and disposed above the base, the top slider structure including a second-tier side wall at the component card engagement side and a plurality of protrusions each having a beveled edge, the top slider structure being slidable between a locked position and an unlocked position, the unlocked position including the plurality of protrusions being displaced away from the component card engagement side relative to the locked position, a bottom one of the plurality of protrusions and the first-tier side wall forming a first receiving slot in the locked position, a top one of the plurality of protrusions and the second-tier wall forming a second receiving slot;
• and
• a biasing element disposed between the base and the top slider structure, the biasing element configured to urge the top slider structure toward the locked position and to compress as the top slider structure is displaced away from the component card engagement side to an unlocked position.
