ELECTRICAL AND AVIONICS SYSTEM
2.
Slide the shield sleeve and inner
sleeve onto one of the coaxial cables
in the order given.
3.
Splice the center conductor. Use
the red cavity of the crimp tool.
4. Shrink the inner sleeve over the
splice, Figure 11-27. Use reflector,
temperature set at 900°F. Keep the hot
air away from shield sleeve.
5. Center and shrink the shield sleeve
over the splice area so that the solder
melts and flows, Figure 11-28. Shield
sleeve braid must overlap coax braid at
both ends.
Use reflector, temperature
set at 900°F.
6. Record BDAR action taken. When
mission is complete, as soon as
practical, repair the equipment/system
using standard maintenance procedures.
11-16. COAX SPLICE FOR RG-180B/U,
RG-124/U, RG-142B/U, RG-302/U, RG-303/U.
GENERAL INFORMATION: There are various
coax splices in the wiring repair kit
that may be used for the different
types and sizes of coaxial cable.
PERSONNEL/TIME REQUIRED:
1 Soldier
15 Minutes
MATERIALS/TOOLS REQUIRED:
Crimp Tool,
AD-1377 (item 10, Appx B)
Coax Splice (item 10, Appx B)
Stripper or Knife
Reflector (item 10, Appx B)
Heat Gun/Heat Source (item 10, Appx B)
PROCEDURAL STEPS:
1.
Prepare coax cable, Figure 11-26.
Refer to Table 11-5.
2.
Slide shield sleeve, inner sleeve,
and filler sleeve onto one of the
coaxial cables in the given order.
3. Splice the center conductor. Use
the red cavity of the crimp tool.
4.
Shrink the filler sleeve over the
splice. Use reflector, temperature set
at 900°F. Keep hot air away from inner
and shield sleeves.
5.
Shrink the inner sleeve over the
splice, Figure 11-27. Use same
reflector and temperature.
Keep hot
air away from shield sleeve.
6. Center and shrink the shield sleeve
over the splice area so that the solder
melts and flows, Figure 11-28. Shield
sleeve braid must overlap coax braid at
both ends. Use same reflector and tem-
perature.
7.
Record BDAR action taken. When
mission is complete, as soon as
practical, repair the equipment/system
using standard maintenance procedures.
11-17. COAX SPLICE FOR RG-9B/U,
RG-214/U, RG-225/U, RG-393/U.
