DPX*MA Crimp
Coaxial Cable Assembly Recommendations (Continued)
For Code V
1. Trim cable to dimensions shown below.
A. Push ferrule under braid as far as it will go and press braid down tightly around ferrule.
B. Solder ends of braid to ferrule by applying a small amount of solder. Avoid excess solder as it would
cause braid to swell up.
C. Remove any solder exceeding the .349 (8.86) max. diameter.
D. Check the .075 (1.90) max. dielectric extension, retrim if necessary.
3. A. Place rear insulator over dielectric and conductor into contact.
B. Solder contact to conductor through access hole.
C. Remove excess solder from outside of contact.
4. A. Place front insulator over contact.
B. Push parts into coaxial shell.
C. 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].
For Codes AB, AD, AE, AF and AG
Setp 1 - Trim cable as shown.
Step 2 - Flare out ends of braid to permit entry of ferrule.
Step 3 - Complete termination per instructions as shown below.
a. Push ferrule under braid as far as it will go. Trim off braid extending beyond shoulder of ferrul, if
necessary.
b. While holding ferrule in place pull crimp sleeve forward over braid until it is tight against shoulder on
ferrule. Push firmly against face of ferrule to make sure it is up tight.
c. Trim dielectric to the .035 (0.89)/ .030 (0.76) dimension.
d. Carefully push inner conductor through rear insulator.
e. While holding rear insulator firmly against ferrule, trim conductor to .156 (3.96)/.146 (3.71)
dimension.
f. Place contact over conductor and solder.
g. Place front insulator over contact and then push assembly into coaxial shell.
h. Place parts in jaw of crimp tool. Locate jaws at start of chamfer on crimp sleeve. Press
Sleeve firmly into coaxial shell and crimp. Use Daniels crimp tool HX4-210.
