Caring for Connectors
Making Connections
Alignment of precision 7mm connectors is made easier by the fact that the
connector sleeve on one of the connectors must be extended fully (and the sleeve on
the other connector retracted fully) in order to make the connection. Extending the
sleeve creates a cylinder into which the other connector fits.
If one of the connectors is fixed, as on a test port, extend that connector sleeve and
spin its knurled connector nut to make sure that the threads are fully extended, while
on the other connector, fully retract the connector sleeve.
To Make a Preliminary Connection
Align the two connectors carefully and engage the connector nut over the exposed
connector sleeve threads on the other connector.
Gently turn the connector nut until a preliminary connection is made. Let the
connector nut pull the two connectors straight together. Do not twist one connector
body into the other (as you might drive a screw or insert a light bulb) as this is
extremely harmful and can damage the connectors.
When the mating plane surfaces make uniform, light contact, the preliminary
connection is tight enough. Do not overtighten this connection.
NOTE
At this stage all you want is a connection in which the outer conductors make gentle
contact at all points on both mating surfaces. Very light finger pressure (no more
than 2 inch-ounces of torque) is enough.
