4、guration (see table II) Example: AA59590/24ET48E is the PIN for a nickel plated, 4.8 inches (122 mm) long card holder with a visual lock indication and a screw self-locking element. The card holder also features two tapped 0-80 UNF mounting holes for use with fasteners. SALIENT CHARACTERISTICS. Inte
5、rface and physical dimensions. The card holders supplied to this CID specification sheet shall be as specified herein (see figures 1, 2, 3, 4, and table I) and meet the general requirements of CID AA59590. Material. Unless otherwise specified herein, the card holder materials shall be as specified i
6、n AA59590. Performance. Card holders shall hold the circuit card assembly it is attached to firmly in its installed position and prevent loosening or movement as a result of shock and vibration. The card holder shall also provide a thermal transfer path from the circuit card assembly to the cold pla
7、te or heat sink surfaces. Actuating screw hex drive socket. The dimension for hex drive socket shall be as specified on figure 1. Screw retention (see figure 2). The screw retention feature is intended to prevent the unintentional disassembly of the card holder. The self-locking nut used for the scr
8、ew retention feature shall be fabricated of a corrosion resistant material. Visual lock indicator (see figure 3). Card holders shall have a visual indicator to show when the card holder assembly is in its relaxed (unlocked) state. When the card holder assembly is in the relaxed state, the end of the
9、 actuating screw shall display a red band on the side of the screw. When the actuating screw on the card holder has been tightened so that the assembly is in the expanded (locked) position, this red band shall be concealed.
