Secondary Method:
Solder a Flat Braid (item 4,
Figure A-2
) to the shield exposed through the window of the prepared
cable assembly. 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 0.75 inches of Teflon heat shrinkable tubing
(item 3,
Figure A-2
) 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 and the
Flat Braid (item 4,
Figure A-2
) to be attached.
Teflon Heat Shrinkable Tubing:
Reference the following MIL-Spec for Teflon heat shrinkable tubing (M23053/5-X-Y).
4. At the same end of the shielded cable and ahead of the previous shield termination, strip back
“Float Min” to “Float Max” (
Table A-2
) length of jacket and shield to expose the insulated center
conductors (
Figure A-2
). The “Ideal Float” length may be best to build optimally.
Preferred Method:
The jacket and shield should be cut off at the same point so no shield is exposed. Slide 0.75 inches
minimum of Teflon heat shrinkable tubing (item 5,
Figure A-2
) onto the cable and use a heat gun
to shrink the tubing. The chosen size of heat shrinkage tubing must accommodate the number of
conductors present in the cable.
Secondary Method:
Leave a max 0.35 inches of shield extending past the jacket. Fold this 0.35 inches of shield back
over the jacket. Slide a solder sleeve (item 5,
Figure A-2
) over the end of the cable and use a heat
gun approved for solder sleeves to secure the connection. The chosen size of solder sleeve must
accommodate the number of conductors present in the cable.
5. Strip back approximately 0.17 inches of insulation from each wire of the shielded cable (item 2,
Figure A-3) and crimp a contact (item 6, Figure A-3) to each conductor. It is the responsibility of
the installer to determine the proper length of insulation to be removed. Wire must be visible in
the inspection hole after crimping and the insulation must be 1/64 – 1/32 inches from the end of
the contact as shown in Figure A-3.
