ASSEMBLY PROCEDURE
The BNC Connector consists of a plug assembly, a
contact, a clamp, a gasket, a washer, and a nut.
1. Slide nut, washer and gasket over cable end;
then strip outer cable jacket using the
recommended strip-length dimension in fig. 7b.
2. Slide clamp over cable braid and position it
against the cable jacket. After clamp is
properly positioned, comb out the braid.
3. Fold cable braid over the clamp and trim it so
that it is positioned against the clamp collar.
See figures 7c and 7d.
4. Using the dimension in figure 7e, strip
dielectric to expose the center conductor. If
applicable, tin the center conductor.
5. Solder contact to the conductor (using standard
soldering techniques), making sure contact is
bottomed on cable dielectric. See figure 7f.
DO NOT allow a hot soldering iron to touch
cable dielectric. Certain cable dielectric
materials, such as polypropylene, will expand
if they come in contact with a hot soldering
iron.
6. Insert contact into plug assemble until contact
snaps into place. See figure 7g.
7. Thread nut into plug assembly until it is secured.
Recommended cable clamp tightening torque is
2.8–3.4 N•m [25-30 in.-lb.], using a 7/16"
wrench. See figure 7h.
