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.

Claims

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.

2. 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; and

a secondary circuit board supported by the board, the secondary power distribution circuitry mounted on the secondary circuit board.

5. The system according to claim 2, comprising secondary power distribution circuitry supported by the board and configured to provide the command, and a connector supported on the board and in communication with a control remote from the board, the connector in communication with the secondary power distribution circuitry, and the control configured to send the command.

3. A power distribution panel comprising:

a board supporting plug-in pins receiving the 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;

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;

secondary power distribution circuitry supported by the board and configured to provide the command; and

a secondary circuit board supported by the board, the current-sensing circuitry mounted on the secondary circuit board.

4. A power distribution panel comprising:

a board supporting plug-in pins receiving the 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;

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;

secondary power distribution circuitry supported by the board and configured to provide the command; and

a secondary circuit board supported by the board, the secondary power distribution circuitry mounted on the secondary circuit board.

6. The system according to claim 4, comprising a connector supported on the board and configured to communicate with a control remote from the board, the connector in communication with the secondary power distribution circuitry.
