  • Electronic module insertion and retraction mechanism
    Patent number: 4597173
    Abstract: A mechanism for inserting and aligning electronic modules, especially in se configurations, is provided with removable ring or sleeve whereby the module assemblies may be automatically retracted. The removable ring or sleeve is installed near the threaded end of each mounting shaft. When a shaft is unscrewed from the chassis the ring or sleeve bears against a shoulder formed in the end-portion of the module assembly heat sink frame, thereby providing a lifting force on the module assembly. The ring or sleeve is easily installed or removed through an opening in the side of the end-portion.
