DPX ARINC 404
Coaxial Cabie Assembly
ITT Cannon recommends resistance soldering for all
solder contacts, particularly for RF cable where
excessive heat will damage the dielectric. Wires
For Codes A, B, C, D, and E
1. Cut cable evenly. Trim to dimensions as shown
on page 56. Care should be taken not to injure
the conductor or dielectric.
2. Remove inner contact from coaxial assembly
and solder it to inner conductor of cable.
3. Push inner contact back into coaxial assembly.
4. Pull outer conductor over coaxial shell, and
solder.
5. Apply shrink sleeving after assembly.
For Codes I and J
1. Cut cable evenly. Trim to dimensions as shown
on page 56. Care should be taken not to injure
the conductor or dielectric.
2. Comb braid, tin conductor and remove flux.
3. Remove solder pot cover. Insert cable and
solder conductor to contact. The dielectric
should butt against contact solder pot.
4. Replace solder pot cover and solder braid to
ferrule.
5. Apply shrink sleeving after assembly.
For Codes K
1. Cut cable evenly. Trim to dimensions as shown
on page 56. Care should be taken not to injure
the conductor or dielectric.
2. Unscrew cap and remove spacer and inner
contact from coaxial assembly.
3. Push cable through center of cap and spacer.
4. Solder inner. contact to inner conductor of
cable.
5. Push inner contact back into coaxial shell as-
sembly and attach cap.
6. Separate outer conductor of cables into two
pigtails 180˚ apart.
7. Attach on pigtail to each end of cap strip and
solder.
8. Apply shrink sleeving after assembly.
For Codes Z and AA
1. Cut cable evenly. Trim to dimensions as shown
on page 56. Care should be taken not to injure
the conductor or dielectric.
2. Solder inner conductor to coaxial contact
through side slot in coaxial with outer sleeve
pushed back on cable.
3. Pull sleeve forward over braid and solder
through holes in sleeve.
4. Solder sleeve to coaxial body.
DPX Solder
should be pre-tinned. Bushing, endbells, and junc-
tion shells (where applicabe) must be slipped over
wire bundles before soldering is started. Consult
factory for types not shown. The mechanical steps
