B-9 Method B.1 (Quick Term) For Shield Termination - Garmin GDU 370 Installation Manual

Connect a Flat Braid (item 4) 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-9). Make this
connection using an approved shield termination technique.
FAA AC 43.13-1B Chapter 11, Section 8 (Wiring Installation Inspection Requirements)
may be a helpful reference for termination techniques.
Preferred Method:
Slide a solder sleeve (item 3) onto the prepared cable assembly (item 2) and connect the
Flat Braid (item 4) to the shield using a heat gun approved for use with solder sleeves. It
may prove beneficial to use a solder sleeve with a pre-installed Flat Braid versus having
to cut a length of Flat Braid to be used. The chosen size of solder sleeve must
accommodate both the number of conductors present in the cable and the Flat Braid
(item 4) to be attached.
Reference Section B.3.2 for recommended solder sleeves and flat braid. The same
recommendations are applicable to this technique.
Secondary Method:
Solder a Flat Braid (item 4) to the folded back shield on the prepared cable assembly (item 2). Ensure
a solid electrical connection through the use of acceptable soldering practices. Use care to avoid
applying excessive heat that burns through the insulation of the center conductors and shorts the
shield to the signal wire. Slide a minimum of 0.75 inches of Teflon heat shrinkable tubing (item 3)
onto the prepared wire assembly and shrink using a heat gun. The chosen size of heat shrinkage
tubing must accommodate both the number of conductors present in the cable as well as the Flat
Braid (item 4) to be attached.
Teflon Heat Shrinkable Tubing:
Reference the following MIL-Spec for general Teflon heat shrinkable tubing
(M23053/5-X-Y)
