Apparatus for directing power to a hot swapped circuit board
View Patent ↗An apparatus comprising a chassis and a cassette. The chassis includes a first electronic circuit board with a first connector, chassis flex circuitry with a disengageable contacts, a controller in communication with the chassis flex circuitry, and a power supply in communication with the controller and the first electronic circuit board. The cassette is selectively securable to the chassis, the cassette including a second electronic circuit board with a second connector, and a cassette handle with cassette flex circuitry that includes a switch and disengageable contacts, wherein securing the cassette to the chassis positions the disengageable contacts of the cassette flex circuitry in engagement with the disengageable contacts of the chassis flex circuitry to form a circuit and positions the first connector in electronic communication with the second connector, and wherein the circuit allows the controller to detect the condition of the switch. A switch trigger is disposed on the cassette handle to actuate the switch, wherein the switch trigger selectively locks or unlocks the cassette to the chassis.
1. An apparatus comprising: a chassis including a first electronic circuit board with a first connector, chassis flex circuitry with a disengageable contacts, a controller in communication with the chassis flex circuitry, and a power supply in communication with the controller and the first electronic circuit board; and a cassette selectively securable to the chassis, the cassette including a second electronic circuit board with a second connector, and a cassette handle with cassette flex circuitry that includes a switch and disengageable contacts, wherein securing the cassette to the chassis positions the disengageable contacts of the cassette flex circuitry in engagement with the disengageable contacts of the chassis flex circuitry to form a circuit and positions the first connector in electronic communication with the second connector, and wherein the circuit allows the controller to detect the condition of the switch; and a switch trigger on the cassette handle to actuate the switch; and wherein the switch trigger selectively locks or unlocks the cassette to the chassis.
2. The apparatus of claim 1 , further comprising:
a spring to maintain the switch in a specified position.
3. The apparatus of claim 1 , wherein the chassis further comprises an access cover that selectively completes the chassis flex circuitry.
4. The apparatus of claim 1 , wherein the disengageable contact is comprised of a metal tab.
5. The apparatus of claim 1 , further comprising:
a spring biasing the switch trigger to actuate the switch.
6. The apparatus of claim 1 , wherein the chassis flex circuitry is disposed upon the first electronic circuit board.
7. The apparatus of claim 1 , wherein the switch is a surface mount switch.
8. The apparatus of claim 1 , further comprising an indicator light emitting diode (LED) controlled by the controller for indicating a quiescent state of the second electronic circuit board.
9. The apparatus of claim 4 , wherein the metal tab includes gold contacts.
