AAA SERIES Q-G
Switchcraft introduces the AAA Series or Q-G
connectors.The Q-G
plug, 3 through 7 pins or contacts. The unique features are the easy
twist on combination handle/strain relief, and the reduced number of
parts to assemble. With the insert built into the front shell, and the
strain relief preloaded into the handle, the end user has only two
parts to assemble – slide the handle onto the cable, solder the
terminations, and twist on the handle. As the handle is tightened, the
strain relief tightens around the outer jacket of the cable. A ramp on
the strain relief keeps it from rotating around the cable jacket and
twisting the cable. The strain relief was designed to accommodate
the most popular cable sizes. A rugged die-cast metal handle insures
optimum protection, and increases signal shielding. Popular options
include black and gold finishes, as well as a lower cost plastic
handle version.
