4、xample: AA59590/15BJ48D is the PIN for a black anodize finished, 4.8 inch (121.9 mm) long card holder with a lock nut on the screw for captivation. The card holder also features two counterbore holes for use with rivet fasteners, a lockwasher and flat washer under the screw head, and a self-locking
5、element on the end of the actuating screw for added resistance to loosening. SALIENT 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
6、of vibration, and provides from 2 to 4 degrees C/W/inch thermal resistance transfer 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 holde
7、rs supplied to this CID specification sheet shall be as specified on figures 1, 2, 3, and 4, in table I, and AA59590. Screw retention locknut (see figure 2). Card holders shall have a screw retention locknut intended to prevent unintentional disassembly of the card holder. The locknut shall be fabri
8、cated 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 dimension of 3.0 mm (0.118 inch) for mounting options “G“ and “M“
9、. Cold plate slot width dimensions (when applicable). The recommended cold plate slot width to accommodate the circuit card assembly with attached card holder is .425 inch (10.80 mm) plus the thickness of the printed board of the circuit card assembly (see AA59590).

13、AA59590/15B 3 Nominal installation torque. When card holders are used in cold plate applications, the nominal installation torque of each card holder shall be as follows: 16 to 20 inch-pounds (1.8 to 2.3 N-m) for assemblies using no options or option “W“ and 17 to 21 inch-pounds (1.9 to 2.5 N-m) for
14、 assemblies using options “E“ or “D“. Finish. The finish designator shall be as specified in AA59590. The finishes available for this CID specification sheet are as follows: “B“ (black anodize), “C“ (gold chemical film), “H“ (hard black anodize), or “R“ (clear chemical film). Mounting. The mounting
15、designators shall be as specified in AA59590. The mounting options available for this CID specification sheet are as follows: “J“ (rivet mounting holes), “N“ (no mounting holes), “R“ or “T“ (tapped 080 UNF 2B holes), “V“ or “S“ (tapped 256 UNC 2B holes), or “G“ or “M“ (tapped M2.5 x.45 metric holes)
16、. Card holders using mounting option “J“ may be shipped unassembled. See figure 1 and table I for mounting hole spacing requirements. Rivet mounting holes. The holes used for rivet mounting shall be .136 inch (3.45 mm) diameter through holes, countersunk 100 degrees by .190 to .200 inch (4.83 to 5.0
17、8 mm) diameter with an access/clearance counterbore hole of .190 to .200 inch (4.83 to 5.08 mm) diameter by .300 inch (7.62 mm) deep. Rivets. This card holder uses rivet style B as specified in AA59590 when rivet mounting is used. Mounting hole locations (when specified). Two mounting holes are requ
18、ired on card holders less than 5.30 inches (134.6 mm) in length. Three mounting holes are required on card holders 5.30 inches (134.6 mm) or greater in length. The third mounting hole, when present, shall be centered on the mounting body. See figure 1 and table I for mounting hole locations and spac
19、ing requirements. Length, expanded, and relaxed dimensions. The length, expanded, and relaxed dimensions shall be as specified on figure 1.
