New connectors for daughtercards allow higher current-carrying capacities

13 July 2005 Interconnection

FCI has expanded its AirMax VS backplane connector system to include power connectors to address customer requirements for increased current-carrying capacity between the backplane and daughtercards in chassis systems.

The right-angle daughtercard connectors are available with either 1x2 or 2x2 contact configurations per 12 mm module. Each module has a total current-carrying capacity of up to 80 A, and 150 V. The corresponding backplane connector features protected contact openings and is UL1950 (Finger Probe) compliant.

The power connectors conform to the Hard Metric format so they can also be used with FCI's Millipacs 2 mm Hard Metric backplane connector system. The contacts are flat except for minimal forming at the plug connector's mating interfaces, which enables the use of high conductivity base metal. Airflow passages in the insulating connector bodies allow air to flow through the fully-mated connectors and over a large percentage of the contact's surfaces, so heat escapes more easily. These design features contribute to the modules' higher current-carrying capacity.

The AirMax VS power modules employ an 'eye of the needle' (EON) compliant tail for press-fit PCB termination. Two available mating lengths for power module contacts provide capability for sequential mating of power and signal contacts.
