Cut cable for assembly of differential twinax contacts. B B 1. Slide heat shrink boot back over cable jacket (not illustrated). 2. Slide ferrule back over cable jacket. CRIMP CABLE 3. Strip cable jacket to expose cable outer braid as illustrated. Ends FERRULE BRAID CRIMP must be cut cleanly and at right angles to the axial plane of the cable284 FERRULE Cable must not be deformed while making cuts. C. 1. Cut braid to length as illustrated to expose inner wires. C D 1. Flair cable braid back over jacket as illustrated. 2. Slide shield support, nubbed end first, over cable inner wires until INNER CABLE BRAID shield support butts against cable braid. WIRES 3. Cut off any inner braids, wraps or cable fillers as close to shield sup- CABLE port as possible. SHIELD BRAID SUPPORT E 1. Cut inner wires to dimension shown. All wires must be cut to equal length. It may be helpful to cut one wire to length. Then cut remaining D wire to equal length as the first wire. 2. Strip inner wires to expose center conductors as illustrated. All wires must be stripped to equal length. CRIMP INNER F 1. Observe the front insulators keyway. When the inner pin assembly is FERRULE WIRES held in the vertical position (with inner pin contacts on top), the inner pin contact with the insulator keyway to its left will be positioned at the SHIELD .279 9 oclock orientation position, when viewing the pin assembly from SUPPORT CENTER CABLE BRAID the mating end (for inner socket contacts, the insulator keyway CONDUCTORS should be positioned to the right of the inner socket desired at the E mating 3 oclock orientation position, when viewing the socket assembly from the mating end). INNER 2. Carefully insert cable center conductors into solder wells, taking care CRIMP WIRES to maintain indicated length145 FERRULE 3. Solder inner contact to cable center conductor. It may be helpful to pre-tin the wire and solder well.

ASSEMBLY 2. Flair cable braid over outer contact body, then slide crimp ferrule over braid as illustrated. Trim G SHIELD excess cable braid. SUPPORT 3. Crimp outer contact body in the area indicated using crimp tools listed in table below. I 1. Slide heat shrink boot over rear of contact assembly to indicated length, then shrink in place.
