Coaxial Cable Assembly Recommendations
LITTLE CAESAR Contact Assembly Data
For Codes F, S and T
1. Strip and trim cable as shown on page 56.
2. Solder inner conductor to coaxial contact with crimp ring over braid and rear insulator over inner
conductor.
3. Insert cable into coaxial with shell under braid. Crimp ring with Cannon crimp tool CA58073.
For Codes G, H and R
1. Strip and trim cable as shown on page 56.
2. Solder inner connector to coaxial contact with crimp ring pushed back on cable.
3. Insert cable into coaxial and pull ring forward over braid. Crimp ring with Cannon crimp tool
CA58073-0001 or CCT-408M. After crimping, crimp ring must not exceed .252 (6.40) diameter.
For Codes U
1. Strip and trim cable as shown on page 56.
2. Slide crimp ring over braid and jacket of cable.
3. Unbraid exposed portion of braid and fold braid wires backward over outside of crimp ring.
4. Insert prepared wire into right angle fitting of shell assembly. Conductor should be aligned in slot of the
center contact. Crimp with Cannon tool CCT/C10.
5. Solder center conductor of cable to contact. Insert cap and solder in place.
For Codes AA
1 . Slip ferrule over cable jacket. Trim outer jacket. Comb out braid as shown. Retrim braid.
2. Bend up combed out braid at right angles to cable. Slide ferrule up to bend and fold braid back against
ferrule.
3. Slide rear insulator over dielectric as shown. Press insulator firmly against folded back braid and trim
dielectric flush with insulator. Then cut inner conductor to length shown.
4. Place contact over conductor. Press contact and insulator firmly against braid and solder contact to
conductor.
5. Push cable assembly into shell, pressing against rear of ferrule and crimp area shown with T. & B.
#WT-400 Crimp Tool while making sure parts do not move out of place.
For Codes AC
1 . Trim jacket to .680 (17.27)/.660 (16.76) dimension. Then slide ferrule over braid until it stops
against jacket, and comb out exposed portion of braid.
2. Fold combed braid over ferrule as shown. Then trim dielectric to .070 (1.78)/.060 (1.52) dimension
and slide rear insulator over dielectric until it presses against braid.
3. Press insulator against braid and trim inner conductor to .247 (6.27)/.237 (6.02) dimension. Then place
contact over conductor and crimp with MS3191-3 (do not use MS3191-1). Press parts firmly
against locator during crimping operation.
4. Place front insulator over contact. Push parts into coaxia! shell. While holding parts firmly against stop
shoulder in coaxial shell, place jaw of crimp tool at back end of shell and crimp. Use Buchanan crimp
tool #612991 (.343 [8.71) across hex].
