1、INCHPOUND AA59590/1B 24 December 2010 SUPERSEDING AA59590/1A 5 July 2003 COMMERCIAL ITEM DESCRIPTION SPECIFICATION SHEET HOLDERS, ELECTRICAL CARD, WEDGE RETAINERS, 3 PIECE, SCREW ACTUATED DRIVE, .225 X .260 INCH BODY SIZE, WITH LEVER ACTION LOCKING The General Services Administration has authorized
2、the use of this commercial item description (CID) for all federal agencies. The complete requirements for procuring electrical card holders described herein shall consist of this document and the latest issue in effect of AA59590. SCOPE. This CID specification sheet covers 3 piece card holders that
3、use a lever, with a locking feature, to actuate wedges to hold circuit card assemblies into their installed positions in heat sinking devices (cold plates, heat exchanger) or other applications. Card holders covered by this CID specification sheet are intended to provide 60g/6ms resistance to shock,
4、 withstand 25 G-rms of vibration and provide 2 to 4 degrees C/Watts/inch thermal resistance between the circuit card assemblies and the heat sink surfaces. Items covered by this CID specification sheet are intended for commercial/industrial applications. CLASSIFICATION/PART OR IDENTIFICATION NUMBER
5、(PIN). This CID specification sheet uses a classification system which is included in the Part Identification Number (PIN) as shown in the following example (see notes). AA59590 CID number /01 Applicable CID sheet B, C, E, H, P, R Finish F, G, J, V Mounting * * Length L, R, U Facing Example: AA59590
6、/01GF28U is the PIN for an gold chemical film finished, 2.8 inch (71.1 mm) long card holder with an actuating lever that locks the card holder into its installed position. The card holder also features two tapped mounting holes for use with 256 UNC 2B fasteners. SALIENT CHARACTERISTICS. Performance.
7、 Card holders shall hold the circuit card firmly in place providing high resistance to shock and vibration while providing maximum thermal transfer. The direct clamping force of configuration A card holders is approximately 120 pounds (534 Newtons) when adjusted in accordance with the recommended pr
8、ocedure. 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 herein and the general CID. Cold plate slot width. The recommend cold p
9、late slot width to accommodate the circuit card assembly with attached card holder is .300 inch (7.62 mm) plus the thickness of the printed board of the circuit card assembly (see AA59590). Configuration. The configuration of a card holder shall be as specified in table I. The details of a particula
10、r configuration consist of those on figure 1. AMSC N/A FSC 5998 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AA59590/1B 2 Finish options. The finish designator shall be as specified in AA59590. The finishes available for this CID specification she
11、et are as follows: “B“ (black anodize), “C“ (gold chemical film), “E“ (electroless nickel), “H“ (hard black anodize), “P“ (electrodeposited nickel), or “R“ (clear chemical film). Mounting options. The mounting designators shall be as specified in AA59590. The mounting options available for this CID
12、specification sheet are as follows: “F“ (tapped metric M2 x 0.4 holes), “G“ (tapped metric M2.5 x 0.45 holes), “J“ (rivet mount holes with counterbore and countersink), or “V“ (tapped 256 UNC holes). See figure 1 for mounting hole spacing requirements. Rivet mount holes. The holes used for rivet mou
13、nting shall be .066/.073 inch (1.68/1.85 mm) diameter, countersunk 100 degrees by .140 inch (3.56 mm) diameter through holes with a counterbore of .156 inch (3.96 mm) diameter by .200 inch (5.08 mm) deep. Rivets. This card holder uses rivet style A as specified in AA59590 when rivet mounting is used
14、. Length, expanded, and relaxed dimensions. The length, expanded, and relaxed dimensions shall be as specified on figure 1. The length designator shall be as specified in AA59590 and the available lengths for this CID specification sheet are listed in table I. Facing. This card holder is available f
15、or mounting in either the left hand, right hand, or universal position. The universal card holder is depicted by configuration A on figure 1. Left and right facing card holders are depicted by configuration B on figure 1 and figure 2. Universal card holders shall include a suffix “U“ in the PIN. Lef
16、t facing card holders shall include a suffix “L“ in the PIN. Right facing card holders shall include a suffix “R“ in the PIN. Lever. A lever-action device shall be used to expand the card holder to secure the attached circuit card assembly in its installed position. When in the relaxed state, the ca
17、rd holders shall allow the circuit card assembly to be placed into or removed from its installed position with zero insertion force to a slight extraction drag. To secure the circuit card assembly in place, the lever shall be actuated, to become perpendicular with the card holder, and parallel with
18、and towards the circuit card. TABLE I. Additional assembly dimensions (see figure 1).
