1. Identify connector parts. (3 piece parts)
2. Strip cable to dimensions shown. Do not nick braid, foil or center con-
ductor. Cut foil flush with dielectric, do not remove foil. Make sure that
dielectric is clean and free from all particles. Tin center conductor,
keeping solder amount to a minimum. Slide crimp sleeve onto jacket
of cable.
3. Flare braid and slide body assembly over foil and dielectric, then un-
der braid. Make sure cable center conductor is contained within con-
nector contact, but do not allow foil and dielectric to enter body access
port. Solder center conductor to contact through the rear access port.
Use a minimum amount of solder for a full fillet joint. .020 (0.51) Diam-
eter solder is recommended.
4. Arrange braid uniformly around crimp stem. Slide crimp sleeve for-
ward and crimp using Johnson Components
TM
hand crimp tool 141-
0000-913 and recommended crimp die hex. Place expansion cap in
access port and seat with recommended Diameter flat punch.
