Figure 2-1 BNC Connector Assembly Drawing
A. Trim coax outer insulation back 0.50"
B. Trim braid (not center conductor or insulation) back 0.25".
C. Strip Insulation back 0.120".
NOTE
Place the ferrule over the coax braid, flush against the coax outer insulation before performing the
next step if the outside diameter of the coax braid is smaller than the inside diameter of the center
connector sidewall opening.
D. Insert cable (center conductor, dielectric and shield braid) through the sidewall of the connector
and solder the center conductor to the center pin of the connector.
NOTE
When using low loss cable it may be necessary to flatten the solid wire center conductor slightly so it
can fit the slot on the RF connector center pin. When soldering, avoid applying excess heat to the
connector body, and center conductor insulator.
E. Heat the outside of the connector sleeve and at the same time apply solder between the braid and the
sleeve. Continue to apply heat until the solder flows evenly.
F. Install 50

Matching Bushing.
G. Insert connector cap and tack solder in two places.
