  • Linecard to chassis securing
    Patent number: 8233285
    Abstract: A holder secures a linecard to a chassis. The holder acts as a releasable expansion bolt. To alleviate tolerance requirements for the linecard and/or chassis, the holder secures with minimal additional pressure being applied to force the linecard against the chassis. Rather than screwing a linecard face plate to the chassis card guide, the holder locks the linecard in place without requiring movement of the face plate against the chassis card guide. A gap may remain between the face plate and the chassis, substantially allowing for a desired amount of insertion of electrical connectors without adverse pressure or movement caused by the securing.
