Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a
connection is made. Metal particles from the connector threads may fall into
the connector when it is disconnected. One connection made with a dirty or
damaged connector can damage both connectors beyond repair.
Magnification is helpful when inspecting connectors, but it is not required and
may actually be misleading. Defects and damage that cannot be seen without
magnification generally have no effect on electrical or mechanical
performance. Magnification is of great use in analyzing the nature and cause of
damage and in cleaning connectors, but it is not required for inspection.
Look for Obvious Defects and Damage First
Examine the connectors first for obvious defects and damage:
— Plating
— Bare metal showing
— Burrs or blisters
— Deformed threads
— Center conductors
— Bent
— Broken
— Misaligned
— Concentricity
Connector nuts should move smoothly and be free of:
— Burrs
— Loose metal particles
— Rough spots
Any connector that has obvious defects should be discarded or sent for repair -
refer to “Contacting Keysight” on page 5-4 .
Devices with damaged connectors should be immediately discarded or
clearly marked and set aside for repair. A damaged device will in turn
damage any good connector to which it is attached. Determine the cause
of the damage before connecting a new, undamaged connector in the
same configuration.
