Appendix D
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 D-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.
