Abstract: A PIU plug-in/plug-off mechanism for an electronic apparatus, which is capable of efficiently applying a force required for a plugging-in/off operation of connectors to a printed board by pressing a portion of the printed board close to a backplane. An operating handle of a card lever is turned counterclockwise to thereby bring a push pin into abutment with a rear edge of an open recess. When the card lever is further turned in this state, a pressing force for moving a plug-in unit in the insertion direction acts on an engaging member via an arm. This starts fitting the printed board into a plug-in connector without causing warping of the printed board.

Abstract: An electrical circuit pack ejector system provides a preemptive warning to the circuit pack that allows redirection and disabling of circuit pack functionality prior to ejection and subsequent disconnection of power and input/output signal contacts. The ejector system is based on proximity detection that measures the distance between a Hall-effect sensor and a magnet affixed to an ejector arm. The magnetic field strength increases as the magnet approaches the sensor. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a positive ejector engagement is surmised. As the ejector arm rotates away from the sensor, the magnetic field strength around the sensor is reduced. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a negative ejector engagement is surmised. The circuit pack then redirects and disables functions prior to the power and signal connectors physical disengagement.
