Shielded Contact Assembly Procedure
Step 1
Slide sealing boot or sleeve and outer ferrule onto cable and strip cable as shown at right.
After stripping, slide spacer over center conductor as shown for Type 2 and Type 3.
For Type 3 slide spacer under wire braid.
Step 2
Step 3
Step 4
Step 5
Insert stripped center conductor into contact until wire shows through inspection hole and dielectric (Type 1,
Type 4 and Type 5) or spacer (Type 2 and Type 3) butts against contact. Fully seat contact in nest bushing
of crimp tool and crimp in one full stroke. (Follow same crimping procedures except use nest bushing crimp-
ing tool from table above).
Slightly flair out ends of wire braid to facilitate insertion of inner ferrule of body assembly.
Do not comb braid.
Install center contact in body assembly and slide inner ferrule underneath wire braid as shown. Push center
contact until it is locked in place in the body assembly. Pull lightly on cable to make sure that contact is
securely locked in place.
Slide outer ferrule over braid and up against body as shown. There should be no slack in the wire braid.
Crimp the outer ferrule with proper tool from table above. Then for Type 1, Type 3 and Type 5 slide sealing
sleeve toward contact until sleeve touches outer ferrule.
Step 6
Insert the assembled shielded contact into the connector in the same way as the standard contact using
applicable insertion tool (see page 28). This completes assembly for Type 1, Type 2, Type 3 and Type 5.
Step 7
To complete assembly for Type 4, push sealing boot into connector grommet until O-ring riser of boot snaps
into place and seals the assembly.
