Caring for Connectors
Visual Inspection
Light burnishing of the mating plane surfaces is normal, and is evident
as light scratches or shallow circular marks distributed more or less
uniformly over the mating plane surface. Other small defects and
cosmetic imperfections are also normal. None of these affect electrical or
mechanical performance.
If a connector shows deep scratches or dents, particles clinging to the
mating plane surfaces, or uneven wear, clean it and inspect it again.
Damage or defects like dents or scratches, which are deep enough to
displace metal on the mating plane surface of the connector, may indicate
that the connector itself is damaged and should not be used. Try to
determine the cause of the damage before making further connections.
Precision 7 mm Connectors
Precision 7mm connectors, among them APC-7
connectors, should be
inspected visually with the center conductor collets in place, and
whenever the collet has been removed. See Figure A-1.
The collet itself should be inspected for edge or surface damage and for
any signs that the spring contacts are bent or twisted. If they are, replace
the collet. When the collet has been re-inserted, verify that it springs
back immediately when pressed with a blunt plastic rod or with the
rounded plastic handle of the collet removing tool. Never use a pencil or
your finger for this purpose.
