Coax Splice With Cable Braid Over Barrier Sleeves; Coax Repair With Cable Braid Over Barrier Sleeve - Bell OH-58A Technical Manual

TM 55-1520-228-BD
ELECTRICAL AND AVIONICS SYSTEM
MATERIALS/TOOLS REQUIRED:
Coax Splice (item 10, Appx B)
Stripper or Knife
Reflector (item 10, Appx B)
Heat Gun (item 10, Appx B)
PROCEDURAL STEPS:
1. Prepare coax cable, Figure 11-26.
Refer to Table 11-5.
2. Slide the shield sleeve and filler
sleeve onto one of the coax cables in
the order given.
3. Insert center conductors to overlap
in center conductor splice.
sleeves of center conductor splice fit
under cable braids, Figure 11-30.
using reflector, temperature set at
900°F.
4. Shrink the filler sleeve over the
splice. Use same reflector and tem-
perature. Keep hot air away from
shield sleeve.
5. Center and shrink the shield sleeve
over the splice area so that the solder
melts and flows.

6. Record BDAR action taken. When
mission is complete, as soon as
practical, repair the equipment/system
using standard maintenance procedures.

GENERAL INFORMATION:
will be quicker not to replace bulkhead
connectors, junction boxes, or terminal
strips. These circuits can be repaired
by "bridging" the damaged area with
jumper wires spliced in to eliminate the
damaged area or component, Figure 11-32.
LIMITATIONS: Will be dependent on the
type of splice used.
porary repair.
PERSONNEL/TIME REQUIRED:
Will be dependent on the type of
splice used.
Typically 1 soldier,
15-30 minutes per splice.
MATERIALS/TOOLS REQUIRED:
Will be dependent on the type of
splice used.
PROCEDURAL STEPS:
1. Identify wires to be bridged
together.
2. Splice wires and jumper wires
together using one of the splicing
techniques of this chapter.
3. Secure jumper wires after repair
is made.
4. Record BDAR action taken.
