초록 ▼

A self-adjusting insertion/extraction apparatus is disclosed for inserting and extracting a printed circuit (PC) board into and from an electrical connector mounted at the base of a PC board rack, the apparatus being configured to function effectively regardless of limited variations in the height of the PC board. The apparatus includes a lever and a pawl pivotally secured to the PC board, at an edge of the board opposite the connector. A spring resiliently couples the lever to the pawl such that pivoting the lever from a raised position to a lowered position yieldably biases the pawl into engagement with the PC board rack, to insert the board into the rack connector. Further, raising the lever from its lowered position to its raised position moves a portion of the lever into engagement with the rack, to extract the board from the connector. Limited variations in the height of the board are accommodated by corresponding flexing of the spring. Some embodiments are configured to disengage the spring from the pawl after the PC board has been fully installed, to reduce the remnant load on the rack\s back plane.
