Cardcage for circuit cards

摘要

The present invention provides an improved cardcage design. The improvements result from the formation of an integral cardcage side using a construction method involving precision punched sheet aluminum that is precision formed into final configuration. The integral cardcage side design provides ease of assembly for the cardcage while enhancing structural integrity, improves the alignment of circuit cards within the cardcage to the backplane, increases the airflow channels between the card guides, and adapts to incorporate additional features for airflow control. The manufacturability of the cardcage is greatly simplified by reducing the number of parts requiring assembly and by the use of simple and inexpensive tools and assembly techniques.
