Mechanism for engaging and disengaging printed circuit board connectors

摘要

A mechanism for use in insertion and extraction of a first printed circuit board (PCB) to and from a second PCB so as to engage and disengage an electrical connector of the first PCB to and from a corresponding electrical connector of the second PCB. The insertion and extraction mechanism includes a stiffener bar and a mounting block. The stiffener bar is affixed to the first PCB immediately adjacent to the electrical connector for stiffening the first PCB in the vicinity of the electrical connector. The mounting block is affixed to the second PCB immediately adjacent to the corresponding electrical connector. A threaded fastener is carried by the stiffener bar and is engageable with the mounting block. Rotation of the fastener in a first direction causes the first PCB to be inserted to the second PCB which causes the electrical connector to be engaged with the corresponding electrical connector. Rotation of the fastener in a second direction causes the first PCB to be extracted from the second PCB which causes the electrical connector to be disengaged from the corresponding electrical connector. An alignment pin of the stiffener bar is engageable with an alignment opening in the mounting block to insure that the electrical connector and the corresponding electrical connector are properly aligned during insertion and extraction of the first PCB to and from the second PCB.
