Caring for Connectors
Cleaning
Alcohol should be used in liquid rather than spray form. If a spray must
be used, always spray the alcohol onto a cloth or swab, never directly into
a connector.
Very dirty connectors can be cleaned with pure alcohol. Other solutions
that contain additives should not be used.
Carefully avoid wetting the plastic support bead (which is easily
damaged by alcohol) inside the connector and blow the connector dry
immediately with a gentle stream of compressed air.
Precision 7 mm Connectors
When precision 7mm connectors have been cleaned with the center
conductor collet removed, insert the collet and clean the mating plane
surfaces again.
When the connector is attached to a small component, or to a cable,
calibration, or verification standard, the easiest way to do this is to put a
lint-free cleaning cloth flat on a table and put a couple of drops of alcohol
in the center of the cloth. It should be noted that it is not necessary to
remove the collet to use this cleaning method.
Retract the connector sleeve threads so that the connector interface is
exposed. Gently press the contact end of the connector into the cloth
moistened with alcohol, then turn the connector.
Dirt on the connector interface will be scrubbed away by the cloth
without damaging the connector. Blow the connector dry with a gentle
stream of compressed air.
This cleaning method can be adapted even for fixed connectors such as
those attached to test ports. Simply fold the cloth into several layers of
thickness, moisten it, press it against the connector interface, and turn it
to clean the connector. Blow the connector dry with a gentle stream of
compressed air.
