Abstract
A junction box (10) defining an enclosed card cage and including a backplane assembly (200) for interconnecting circuits of daughter cards (130) with associated conductors extending thereinto at an input/output interface. The junction box (10) includes a front panel (50) removable from the front face to permit insertion and removal of respective daughter cards, and includes an array of interior fins (58) engaged with the daughter cards at thermal junctions (64) and an array of exterior fins (52) for dissipating the thermal energy. The rear wall (14) includes shield sections (214) surrounding input/output connectors (208) joined to the backplane assembly. The junction box (10) prevents EMI/RFI leakage therethrough.
