Abstract
An enclosure or containment system for expansion cards includes first and second sub-enclosures that interengage to form an enclosure assembly that substantially surrounds the major surface areas of the expansion card while providing support along some of the edges thereof to provide a protected volume that physically protects and shields the electronic and electrical components on the expansion card while providing enhanced heat transfer therefrom.
Claims8
An enclosure system for substantially enclosing an expansion card therein of the type having an edge connector at a front portion thereof and having a rear edge on a side opposite the front portion thereof, the connector having with a plurality of spaced conductive elements for connection to socket or socket-like receptacle on a motherboard comprising:
- a substantially closed housing defining an interior volume for containing a substantial portion of an expansion card therein, the housing including a first sub-housing having a rear portion and a front portion and a second sub-housing having a rear portion and a front portion, the rear portion of the first sub-housing and the rear portion of the second sub-housing having interengaging formations for connecting the rear portions of the first and second sub-housings together and for defining a channel for receiving a rear edge portion of an expansion card therein, the respective front portions of the first sub-housing and the second sub-housings holding a portion of the expansion card rearwardly of the connector therebetween, and
- a first end plate attached to respective first ends of said first and second sub-housings and a second plate attached to respective second ends of said first and second sub-housings.
An expansion card/enclosure system for connection to socket or socket-like receptacle on a motherboard comprising:
- a substantially closed housing defining an interior volume for containing a substantial portion of an expansion card therein, the expansion card of the type having an edge connector at a front portion thereof and having a rear edge on a side opposite the front portion thereof, the connector having with a plurality of spaced conductive elements, the housing including a first sub-housing having a rear portion and a front portion and a second sub-housing having a rear portion and a front portion, the rear portion of the first sub-housing and the rear portion of the second sub-housing having interengaging formations for connecting the rear portions of the first and second sub-housings together and for defining a channel for receiving a rear edge portion of an expansion card therein, the respective front portions of the first sub-housing and the second sub-housings holding a portion of the expansion card rearwardly of the connector therebetween, and
- a first end plate attached to respective first ends of said first and second sub-housings and a second plate attached to respective second ends of said first and second sub-housings.
