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 recom-
mended strip-length dimension in fig. 6b.
2. Slide clamp over cable braid and position it
against the cable jacket. After clamp is prop-
erly 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 6c and 6d.
4. Using the dimension in figure 6e, strip dielec-
tric to expose the center conductor. If applica-
ble, tin the center conductor.
5. Solder contact to the conductor (using stan-
dard soldering techniques), making sure con-
tact is bottomed on cable dielectric. See fig-
ure 6f.
DO NOT allow a hot soldering iron to touch
cable dielectric. Certain cable dielectric mate-
rials, 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 6g.
7. Thread nut into plug assembly until it is
secured. Recommended cable clamp tighten-
ing torque is 2.8–3.4 N•m [25–30 in.-lb.],
using a 7/16" wrench. See figure 6h.
