Abstract: A method and apparatus for adding shielding for electronic circuit packs. The invention includes a circuit pack cage, which has a first pair of parallel longitudinal circuit pack slots for receiving the circuit packs and further has a first longitudinal shield slot disposed between first pair of circuit pack slots for receiving a conductive sheet member. At least one conductive resilient member is disposed in the first shield slot in electrical coupling with a conductive chassis. Upon sliding the conductive sheet member between the pair of circuit packs and into the shield slot, the resilient member flexibly engages the conductive sheet member and electrically couples the conductive sheet member with the conductive chassis.

Abstract: An improved terminal block for permitting the connection of inputs and outputs of an electronics mainframe module, such as a VXI mainframe module, to external devices, such as devices under test. The improved terminal block includes insertion and ejection levers to ease the connection and disconnection of the terminal block to the module. A ledge of the insertion and ejection lever engages an insertion beating surface on a front panel of the module during the insertion process and is then rotated in the appropriate direction until the terminal block is securely connected to the module. The ledge of the insertion and ejection lever engages an ejection beating surface on the front panel of the module during the ejection process and is then rotated in the appropriate direction until the terminal block is disengaged from the module. The levers can also be shaped in such a manner to permit top and bottom cable routing apertures, as well as a back side cable routing aperture.
