2. DESCRIPTION
Solder Assembly Kit 1055469-1 contains the tooling
required to properly solder TNC and BNC solder-style
connectors to semi-rigid coax cable. The kit contains a
cable fixture sub-assembly, two sets of clamp inserts
for 2.16 [.085] and 3.58 [.141] cable, and two types of
locators that are used to properly align the connector
and cable. The kit also contains a solder gage for
proper spacing of the center contact, and a center
contact holder.
The cable fixture subassembly consists of a fixture
frame, thumbscrew, positioning tool and spring. See
Figure 3. When used with the proper clamp inserts the
assembly holds and locates coaxial cable for
soldering.
3. INSTALLING/REPLACING THE CLAMP INSERT
NOTE
Clamp inserts come in sets of two. Upper and lower
inserts are interchangeable.
i^
1. Select the appropriate clamp inserts. Refer to
Figure 1 for the appropriate clamp inserts.
2. Remove the cable fixture thumbscrew by rotating
it in a counterclockwise direction.
3. Remove the positioning tool by rotating it in a
counterclockwise direction.
4. Remove the clamp inserts from the frame after
the positioning tool is removed.
5. Sandwich the spring in the pockets on the
replacement clamp inserts.
6. Place clamp inserts in the fixture frame and
reinstall the positioning tool.
7. Retighten positioning tool.
8. Reinstall the thumbscrew.
4. TRIMMING CABLE WITH FIXTURE FRAME
The fixture frame is equipped with six trimming holes
designed to remove the outer jacket and cable
dielectric. The side marked with the number 2 is for
trimming 1.78 [.070], 2.16 [.085], and 3.58 [.141]
cable. See Figure 3 and Figure 4. When cable is fully
bottomed during trimming, a strip length of 2.79 [.110]
will result. If different strip lengths are required the
center conductor must be trimmed separately.
The side marked with a number the number "1" is for
trimming cable already mounted in a connector
housing. See the connector specific instruction sheet
for more information.
NOTE
i
Trim blades are NOT included with the kit. Use a
razor blade with 0.38 [.015] maximum thickness.
