Secondary Method:
Solder a Flat Braid (item 4, Figure 22-2) to the shield exposed through the window of the prepared
cable assembly (item 2, Figure 22-1
). Create 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 22-2
) 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 22-2
) 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 (item 2, Figure 22-1
) and ahead of the previous shield
termination, strip back “Float Min” to “Float Max” (Table 22-3
) length of jacket and shield to
expose the insulated center conductors (Figure 22-2
). 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 22-2
) 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 22-2
) 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 22-3) and crimp a contact (item 6, Figure 22-3) to each conductor. It is the responsibility of
the installer to find 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 22-3.
