Publication number: 20140071647Abstract: A computer processor retention device comprises a load frame, a load plate, and a pair of retractable cover members. The load frame may be secured to a circuit board around a processor mounting site. The load plate is pivotally coupled to the load frame and is pivotable between being open for receiving a processor at the processor mounting site and closed in engagement with a periphery of the received processor. The load plate has a window that is open to the processor mounting site when the load plate is closed. The retractable cover members span the window and are alternately movable along a track toward one another to cover the processor mounting site and away from one another to expose the processor mounting site.Type: ApplicationFiled: September 12, 2012Publication date: March 13, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jeremy S.
