Abstract
The coupling apparatus couples two circuit cards to fit into a larger chassis. A coupling element can connect two similar sized circuit cards or two different sized circuit cards together by coupling the first circuit card and the second circuit card to effectively form a combined circuit card of a larger size. The larger size may allow for more features, may make it easier to dissipate heat, may make the circuit cards easier to shield, and/or may allow for the use of larger and less expensive components on the circuit cards.
Claims9
An apparatus, comprising:
- a first module, wherein the first module is a circuit card;
- a second module coupled to the first module, wherein the second module is a circuit card, and wherein the second module is coupled to the first module by a coupling element;
- a front face coupled to the second module to provide an interface between the second module and an external component;
- and
- a back face coupled to the first module to provide an interface between the first module and a backplane.
