B.2 Shield Termination Technique – Method A.1 (Standard)
NOTE
For the following steps please refer to Figure B-l.
1. Attach the Shield Block(s) (Item 2) to the backshell (Item 1) by inserting the flathead screws
(Item 3) through the holes on the Shield Block and threading into the tapped holes on the backshell
(Item 1) (see Figure B-1).
Figure B-2 Method A.1 for Shield Termination
2. At one end of a shielded cable (Item 4) measure a distance between “Window Min” to “Window
Max” (Table B-6) and cut a window (max size 0.35”) in the jacket to expose the shield (Figure B-
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
