ARAP AMP INCORPORATED HARRISBURG, PA 17105 CUSTOMER HOTLINE 1 800 722-1111 ASSEMBLY AND HARDWARE INSTALLATION PROCEDURES FOR AMP-HDI* SERIES 6-ROW CONNECTORS 445269-1 AND 445270-1 IS 9552 RELEASED 7-16-80 RECEPTACLE CONNECTOR 445270-1 PLUG CONNECTOR 445269-1 Fig. 1 1. INTRODUCTION These instructions cover the installation procedures for polarizing keys (AMP* part number 445282-1), and shells (AMP part numbers 445279-1 and 445585-1) used with AMP-HDI Series 6-Row plug connector 445269-1, and connector installation procedure for AMP connectors 445269-1 (plug) and 445270-1 (receptacle). Also covered is installation procedure for guide pins (AMP part number 445287-1) used with the connectors. The connectors are designed to bea mounted onto a backplane/frame assembly (mother- board/daughtercara) . Read these instructions carefully before attempting to install any components in the connectors or installing connector assemblies onto their appropriate boards. NOTE 2. DESCRIPTION (Figure 1) The plug connecter assembly is designed to accept up to four kays, a two-part shell assembly, interfacial seals, and up to four fiber optic size 16 terminus contacts (MIL-T-29504/5}. The receptacle assembly All dimensions on this sheet are in inches. Copyright 1990 by AMP Incorporated. All International Rights Reserved. *Trademark of AMP Incorporated is designed to accept up ta four keys positioned to correspond to the keys in @ mating plug connector assembly. Refer to AMP instruction sheet IS 9560 for information regarding installation and use of interfacial seals. The keys are retained in connector housings with screws which thread into threaded inserts mounted on the side opposite the keys, or into the support plate with threaded holes. The octagonal shape of the keys permits their rotation in eight possible positions. A total of 4,096 different keying combinations is possible. The guide pins are press-fit into the support plate in their respective locations on the motherboard assembly. The receptacle connector housing fits over the pins when installed onto the motherboard, and engages the plug connector housing when it is mated to the receptacle connector. The guide pins provide alignment for connectors when mating. The two-part shell assembly is installed on the frame after the plug connector assembly is installed and soldered on the circuit boards. The shell assembly, which is retained by three captive screws and threaded inserts, provides pin and connector protection, ground- ing continuity for the board, and connector stability.

KEY INSTALLATION (Figure 2) Obtain a quantity of keys and screws sufficient to install the required number of keying positions on the connectors being prepared, Proceed as follows: A customer-supplied fixture, which will not mer the connector housing or touch any portion of the contacts, may facilitate the installation of keys. Tweezers will also aid in positioning keys. A. Plug Connector 1. With the connector positioned so that the contact tails are in the uppermost position, note the location of the four threaded inserts in the connector housing (one at each end and two in the middle}. 2. Now rotate the connector housing so that the contact pins are in the uppermost position and place the keys in the four keying positions. 3. Carefully place screws through the keys and thread them into the inserts. Do NOT tighten at this point. 4. Rotate the keys to the desirad keying positions if this has not been cone and, very carefully, tighten the screws of the keys with a screwdriver until snug. Do NOT overtighten. The recommended torque Is four inch-Ibs. PAGE 2 OF 4 B. Receptacle Connector 1. With the connector positioned so that the contact tails are in the uppermost position, note the location of the single threaded insert in the center position of the receptacles assembly. The three remaining key positions are through-holes. 2. Rotate the connector housing so that the receptacle openings are in the uppermost position and place a key in the center keying position. 3. Rotate the installed key to correspond to the center keying position of the plug connector if this has not been done and, very carefully, tighten the screw of the key with a screwdriver until snug. Recommended torque is four inchIbs. 4. Do NOT put the threes remaining Keys in the receptacle connector at this point. They are re- tained through threaded holes in the motherboard (see Paragraph 6, RECEPTACLE-TO-MOTHER- BOARD INSTALLATION, for Installation procedure. 4, GUIDE PIN INSTALLATION The support plate of the motherboard must be cut out and drilled to the dimensions shown in Figure 3. The guide pins are installed as follows: 1. Make certain that holes are clean and free of any burrs or crilled material. 2. Using a customersupplied insertion fixture (such as an arbor press capable of applying 250 Ibs of pressure), press the guide/ground pins straight (perpendicular within + .002 from center) into the indicated holes (see Figure 3) of the motherboard until the larger diameter of the pin is bottomed on the board surface.AMP-HDi CONNECTORS 445269-1 AND 445270-1 IS 9552 removed from the motherboard, or the board hole clameter is slightly oversize (thereby not allowing a press-fit of the pin, a replacernent pin (445287-2) is aveilabie. The -2 pin hes a tapped hale which allows the installation of a 0-80 UNC screw fromm the bottom side of the motherboard to secure the pin. 5. SHELL ASSEMBLY The sheli assembly consists of two halves which are secured over the soldered plug connector assembly to form a stabilizer, pin protection, and to provide .010-in. float for the board. The shell halves (designated as Side 4 and Side B in Figure 4) are designed to be placed over specific sides of the plug connector. Side A, visually identified by three captive screws, has the numbers 1 and 138 printed on its outer face and is used on the side of the plug connector assembly with the markings F1", F2", F3 and F4 stamped upon it. 4.670 .462 ai 145 2 PLC.

Assembly is as follows: 1. Using AMP Contact Alignment Tool Kit 445506-1, align and then solder the daughter card contact pads to the contact tails of the plug connector. Refer to AMP Instruction Sheet IS 9599 for alignment procedure and use of alignment tool. 2. Place the soldered connector/daughterboard assembly on a clean, level surface, taking care to support the assembly so that it does not fall over and damage the board components or contacts. 3. Place Side A of the shell assembly against the appropriate side of the connector with the cap- tive screws in the uppermost position and allow the raised flanges on the edge of the connector housing to fit into the channel of Side A where the AMP part number, AMP logo, FSCM No., and date code are printed. 4. Place Side B of the shell assembly against the opposite side of the connector and allow the raised flanges on the edge of the housing to fit into the channel of Side B" where the AMP logo, FSCM No., and date code are printed.
