INTRODUCTION This instruction sheet covers the use of the AMP-LEAF Connector Housings which Fig. 1 housings are supplied so contacts and accessories accept can be installed to meet specific circuit requirements. AMP-LEAF Crimp Contacts. Read these instructions carefully befare starting. in fches. 2. DESCRIPTION (Figure 1) Connector housings are available with 6 through 36 dual contact positions on .156-in. centers. Empty All dimensions on this instruction sheet are * Trademark of AMP Incorporated Connector housings may be front or back panel mounted, and will accept single- or double-sided printed circuit (pc) boards. 3. CONTACTS Selection Determine the size of the wire (or wires) to be crimped. Refer to Figure 1 and select a contact that accepts the wire size. PAGE 1 OF 4IS 7037 NOTE ] Contacts designed for 1/16 in. (.062) pe board hausings are not interchangeable with contacts designed for 3/32 in. (.093) pc board housings. Crimping The strip-form contacts listed in Figure 1 are designed to be crimped with standard or miniature applicators used in AMP automatic or semi- automatic machines. Consult your local AMP repre- sentative for assistance in selecting the machine that will best suit your needs. Loose-piece contacts are designed to be crimped with the AMP hand crimping tools listed in Figure 1. Read the AMP instruction sheet packaged with the tool for specific crimping procedures. insertion An insertion tool is not required for inserting contacts inte the connector housings. To insert a contact, proceed as follows: 1. Align the contact with the BACK of the applicable contact cavity. 2. Position contact so the spring is facing the center wall between the upper and lower cavity. See Figure 2. 3. Push contact straight in until it bottoms in cavity. Pull back lightly to be sure locking lance has Jocked in cavity. Extraction AMP Extraction Tools 465195-1, -2, and -4 are designed to extract contacts from AMP-LEAF connector housings. Refer to AMP Instruction Sheet IS 7045, which is packaged with the tools, for proper extraction procedures, 4. DUMMY CONTACTS {Figure 2) Dummy contacts are precrimped standard contacts designed for double-sided pc board applications. These contacts provide additional mechanical pressure for partially loaded connectors. Recom- mendations call for a dummy contact to be placed in each empty cavity that is opposite a standard working contact.

PANEL CUTOUT The connector housings are designed ta be FRONT or BACK panel-mounted. Refer to the layout shown in Figure 3 for the recommended panel cutout. The cutout for BACK panel mounting is larger than the cutout for FRONT panel mounting. After making the cutout, position the connector on the panel and secure it with No. 4-40 screws, lockwashers, and nuts. 6. PRINTED CIRCUIT BOARD LAYOUT! The connector housings are designed to accept 1/16-in. (.055 to .070), or 3/32-in. (.084 to .104) pc boards.

RETAINING SPRINGS (Figure 4) Retaining springs are designed for use in single-sided pc board applications. They are used to increase or balance board retention capabilities of the unused side of the connector. The recommended ratio is one standard retaining spring to seven contacts, or one S-style retaining spring to five contacts. To insert the retaining spring, orient and start the short end into the FRONT of the desired cavity. See Figure 4. Push straight in until the short end snaps in place behind cavity ridge. To extract the retaining spring, use a suitable tool to depress the short end of the spring from BACK of connector. Push spring straight out FRONT of connector.

KEYING PLUGS (Figure 5) Connectors can be polarized with intercontact or on-contact keying plugs. Intercontact keying plugs are designed to fit into slots between the contact cavities (connectors for 1/16-in, pc boards only}, and on-contact keying plugs are designed to fit into an empty contact cavity and fit a connector which accepts either a 1/16 or 3/32-in. pe board. Instruction sheets for insertion and extraction pro- cedures for keying plugs are packaged with the plugs. Refer to AMP Instruction Sheet IS 7068 for keying plug 582501, IS 7339 for keying plug 583274-1, and to IS 7036 for keying plugs 480143 and 582756. PAGE 4 OF 4 Fig. 5 9. COMMONING SPRINGS Commoning springs are designed to bridge two opposing contacts to form a single circuit. The commoning springs are available with or without locking latches. See Figure 6. Refer to AMP Instruction Sheet IS 7419 packaged with the commoning springs for specific applications.
