BACKSHELLS FOR SHIELDING
NSA and SA backshells
LJT NSA (HE308-13) suitable for LJT (MIL-DTL-38999 series I /
HE308), RNJ (HE308) and SJT (VG96912) connectors.
JT SA suitable for JT (MIL-DTL-38999 series II) connectors.
TV NSA suitable for TV-CTV (MIL-DTL-38999 series III) and RNJ LP
connectors.
NSA and SA backshells ensure the shielding by clamping the braid
with a screwing system. The free inner ring avoids twisting of the
braid during screwing. For straight or right angled heat shrink
moulded pieces, please refer to page 14-15.

ASSEMBLY INSTRUCTIONS
NSA and SA backshells
1. Prepare the cable for termination process and slide onto
the cable the items in the order shown on gure 1.
2. Screw the backshell at the rear of the connector.
3. Fold back the braid on the outer jacket and x it
(gure 2)
4. Install the braid as shown on gures 3 and 4:
Release the braid and cover the backshell (a) and
the connector’s shell. Slide the rst ring (b) over the
braid. Fold back the braid on the ring (b) and slide the
second ring (c) over the braid and the rst ring (b).
Screw the last ring (d) at the rear of the backshell. If
necessary, x the extra braid on the outer jacket of the
cable. If this installation (double folding of the braid)
is not possible, refer to gure 5: Slide the rst ring (b).
Release the braid and cover the backshell (a) and the
connector’s shell. Cut the braid as shown. Slide the
second ring (c) over the braid and the rst ring (b).
Screw the last ring at the rear of the backshell.
5. Install the heat-shrink moulded piece.

SQ backshells
1. Prepare the cable for termination process.
2. Screw the backshell at the rear of the connector.
3. Install the braid as shown on  gure 1: Release the braid and
cover the backshell conus. Maintain the braid on the conus
with a small diameter wire in the groove. Fold back the braid
on itself and cut it as shown. Screw the ring over the braid
without twisting it.
4. Install the heat-shrink moulded piece. Figure 1
NSB backshells
1. Prepare the cable for termination process.
2. Screw the backshell at the rear of the connector.
3. If possible, protect the conductors with an insulationg tube
or tape (e) inserted between them and the backshell.
4. Install the braid as shown of  gure 1.
5. Install the heat-shrink moulded piece.
HE308-35, TV35 and SBC backshells
1. Prepare the cable for termination process ( gure 1).
2. Screw the backshell at the rear of the connector.
3. Push the braid over the backshell to the incline point. Milk
the braid as required to remove the slack and insure a snug
 t around the shield termination area ( gure 2).
4. Prepare the band: Roll the band through the buckle slot
twice (the band must be double-coiled). Pull on the band
until the mark is within approximately 6.4 mm (.250 in) of
the buckle slot ( gure 3). The band may be tightened further
if desired.
5. Squeeze the gripper release lever of the banding tool and
insert the band into the front end opening of the tool as
shown on  gure 4 (the circular portion of looped band must
always face downward).
6. Aligning the band and the tool with the shield termination
area, squeeze the black pull-up handle repeatedly using
short strokes until it locks against the tool body (this
indicates the band is compressed to the tool precalibrated
tension).
7. Complete the clamping process by squeezing the grey cut-
off handle.
8. Remove the excess band from the tool.
9. Inspect shield termination ( gure 5). Il the alignment of the
band and the shield in unsatisfactory, tension on the band
can be relaxed by pushing on the slotted release lever on
the top of the tool. Make adjustments as necessary and
squeeze again the black pull-up handle.

(.236 in)). See 1 .
3. Unscrew the nut and slide it back on the jacket. See 2 .
4. Remove the ring. See 3 .
5. Slide the pipe through the backshell and put the backshell back on the jacket. See 4 .
6. Put the ring back. See 5 .
7. Put the backshell back on the pipe. See 6 .
