Apparatus for assisting in the connection and disconnection of a board with an energized circuit
First Claim
1. In a system having an energizable circuit comprised of a plurality of circuit boards and a system DC power supply for energizing the circuit including each of the circuit boards, an apparatus for assisting in the electrical connection and disconnection of a selected one of the circuit boards with the circuit of the system energized, said apparatus comprising:
- second DC power supply means for energizing said selected circuit board only during its connection and disconnection;
power connection means electrically connected to said second DC power supply means and having a board connector for electrical connection to the selected circuit board to be inserted into or removed from the energized circuit; and
control means for controlling said second DC power supply means, said control means controlling the precharging of said selected circuit board to a selected voltage level prior to its insertion into the circuit, and the maintaining of a selected voltage level on said selected circuit board during its removal from the energized circuit.

Abstract
An apparatus for assisting in the electrical connection and disconnection of a circuit board with an energized circuit having a power supply, a power connection electrically connected to the power supply and having a board connector for electrical connection to a circuit board to be inserted into or removed from an energized circuit, and a control circuit for controlling the power supply means. The control circuit controls the pre-charging of a circuit board to a selected voltage level prior to its insertion into a circuit, and maintains a selected voltage level on a circuit board during its removal from an energized circuit.
