Modular primary distribution contact board
First Claim
1. An aircraft power distribution system comprising:
- a power distribution box;
a generator supplying power to the power distribution box;
a load receiving power from the power distribution box;
wherein the power distribution box includes a board supporting plug-in pins receiving power, a contactor supported by the board and configured to selectively provide power to a secondary power distribution connector supported on the board in response to a command, the board including power traces connecting the plug-in pins to the secondary power distribution connector;
a secondary circuit board supported by the board, the current-sensing circuitry mounted on the secondary circuit board; and
a current-sensing circuitry supported by the board and connected to at least one of the plug-in pins and the power traces, the current-sensing circuitry configured to monitor current to the power traces.

Abstract
An aircraft power distribution system is disclosed that includes a power distribution box. A generator supplies power to the power distribution box, and a load receives power from the power distribution box. The power distribution box includes a board supporting plug-in pins receiving the power. A contactor is supported by the board to selectively providing power to a secondary power distribution connector supported on the board. The board includes power traces that are run within the board to connect the plug-in pins to the secondary power distribution connector. Protection and secondary power distribution circuitry is also supported by the board and connected to the contactors and/or power traces by control traces. The power and control traces eliminate loose wiring and harnesses.
