4、 I) W, D, E Configuration Example: AA59590/16CG58 is the PIN for a chemical film finished, 5.8 inch (147.3 mm) long visual lock indicating card holder with a lock nut on the screw for captivation. The card holder also features three tapped mounting holes for use with metric M2.5 x 0.45 fasteners. SA
5、LIENT CHARACTERISTICS. Performance. Card holders shall hold the circuit card assembly firmly in its installed position. When the card holder is installed properly, it is capable of withstanding 60g/6ms of shock, 25 G-rms of vibration, and provides from 2 to 4 degrees C/W/inch thermal resistance tran
6、sfer between the circuit card assembly and the heat sink surfaces. Material. Unless otherwise specified herein, the card holder materials shall be as specified in AA59590. Interface and physical dimensions. The card holders supplied to this CID specification sheet shall be as specified on figures 1,
7、 2, 3, 4, and 5, in table I, and AA59590. Visual lock indicator (see figure 2). Card holders shall have a visual indicator to show when the card holder is in its relaxed (unlocked) state. When the card holder is in the unlocked (relaxed) state, the actuating end of the screw shall display a red band
8、 on the side of the screw. When the actuating screw on the card holder has been tightened (assembly expanded) so that the assembly is in the locked position, this red band shall be concealed. Screw retention (see figure 3). Card holders shall have a screw retention feature intended to prevent uninte
9、ntional disassembly of the card holder. The locknut shall be fabricated of a corrosion resistant material. Actuating screw hex drive socket. The across flats dimension for the hex drive socket shall be as follows: .140 inch (3.57 mm) for mounting options “J“, “N“, “T“, “R“, “V“, and “S“ and a metric
10、 dimension of 3.0 mm (0.118 inch) for mounting options “G“ and “M“.
