Appendix E 173
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.
