B. Shield termination using Method II. To be used when a large number of shielded cables terminate at
a common point.
(1) Prepare individual shielded cables as shown in Figure 204. Use Thomas & Betts Tool Number
WT-093B to slip conductor(s) out of shield. Refer to Figure 205 for wire stripping dimensions.
(2) Slip all prepared shielded cables and all unshielded wires that terminate at the same point
through the appropriate size solder sleeve.
(3) Position sleeve per Figure 205 and use procedure described in 3.A.(3) for shrinking and soldering
of sleeve.
C. Alternate method. To be used when solder sleeves are not available.
(1) Cut the outer jacket around
its circumference four inches from the
end of the cable as shown in
Figure 206.
(2) Push the metal
braid shielding back over the insulated
wire to make a hump.
(3) Make an opening by separating the wires in the metal braid at the hump. Work the insulated
wire through the opening. Push the shielding even further over the wire. Wrap one or two turns
of vinyl tape
around the wire at the base of the hump.
Slide the braid over the taped joint.
CAUTION: DO NOT DAMAGE
THE WIRE INSULATION OR
SHIELDING.
(4) Slide the outer covering
over the pigtail and taped wire. Wrap two
or three turns of tape around
the cut end
of the outer jacket to make
a moisture and dustproof joint.
(5) Cut
the insulated
wire to
proper length,
strip insulation
and
install connector.
(6) Cut the pigtail to length. Enclose pigtail in vinyl sleeving and stake terminal to pigtail.
D. Dead
ending a
shield.
(1) Strip cable and cut heat shrink tubing to length according to dimensions in Figure 207.
(2) refer to Heat Shrinkable Tubing - Maintenance Practices for proper size tubing and further
installation details.
NOTE: Part number D144-50 solder
sleeve is for a single 22 AWG pigtail. For more
than one pigtail or
pigtail larger than 22 AWG use a D144-51 solder sleeve.
NOTE: For Mil-W-16878 Type D shielded cable use shrink tube for a heat sink between the conductor
insulation and the shield.
4. Terminating
Shielded
Cables
A. When terminating shielded cables, the following guide lines should be observed.
(1) Shield terminations
(jumper wires or braid strap) shall
be as short and as straight as possible
to
the back of a connector or to a ground stud.
(2)
Ground shields only where indicated
by the applicable wiring
diagram.
(3) There shall be no
more than two jumper wires (or braid straps)
per ground terminal. If shown on
a wire diagram, it
is permissible to have three braid
straps per ground terminal.
(4) Only jumper shielded cables together as shown on the applicable wiring diagram.
(5) Refer to Table 201 to determine proper solder sleeve for shielded cable to be terminated.
