22.2.3 Shield Termination Technique – Method A.1 (Standard)
NOTE
For the following steps please refer to Figure 22-1 and Figure 22-2.
1. The appropriate number of Jackscrew Backshells will be included in the particular LRU connector
kit.
Figure 22-2 Method A.1 for Shield Termination
2. At one end of a shielded cable (item 2, Figure 22-1
) measure a distance between “Window Min” to
“Window Max” (Table 22-3) and cut a window (max size 0.35”) in the jacket to expose the shield
(item 4, Figure 22-2). Use caution when cutting the jacket to avoid damaging the individual braids
of the shield. When dealing with a densely populated connector with many cables, it may prove
beneficial to stagger the windows throughout the “Window Min” to “Window Max” range. If
staggering is not needed the “Ideal Window” length is recommended.
Suggested tools to accomplish the window cut:
• Coaxial Cable Stripper
• Thermal Stripper
• Sharp Razor Blade
