B.4.4 Quick Term Shield Termination – Method B
If desired, the drain wire termination (item 5) and the floating shield termination (item 7) can be
effectively combined into a “Quick Term”. This method eliminates the float in the cable insulation and
moves the placement of the window which was described by the dimensions “Window Min” and
“Window Max” from Method A. This technique is depicted in Figure B-19.
NOTE
The original purpose for separating the shield drain termination (item 5) from the float
termination (item 7) in Method A was to allow for a variety of lengths for the drain wires
so that the shield drain terminations (item 5) would not all “bunch up” in the harness and
to eliminate loops in the drain wires. If Method B is chosen, as described in this section,
care must be taken to insure that all drain shield terminations can still be inspected. With
connectors which require a large number of shield terminations it may be best to use
Method A. This will allow the drain shield terminations (item 5) a larger area to be
dispersed across.

1. At the end of the shielded cable (item 4), strip “Quick Term Min” to “Quick Term Max” (Table
B-12) length of the jacket to expose the shield. Next trim the shield so that at most 0.35 inches
remains extending beyond the insulating jacket. Fold this remaining shield back over the jacket.
2. Connect a flat braid (item 6) to the folded back shield of the prepared cable assembly. The flat
braid should go out the front of the termination towards the connector. It is not permitted to exit
the rear of the termination and loop back towards the connector (Figure B-19). Make this
connection using an approved shield termination technique.
