- not the position of the tip. The male contact pin slides into the female contact
fingers and electrical contact is made by the inside surfaces of the tip of the female
contact fingers on the sides of the male contact pin.
50 Ohm Type-N Connectors
NOTE
No Type-N connector should ever be used when there is any possibility of
interference between the shoulder of the male contact pin and the tip of the female
contact fingers when the connectors are mated. In practice this means that no
Type-N connector pair should be mated when the separation between the tip of the
female contact fingers and the shoulder of the male contact pin could be less than
zero when the connectors are mated. Gage Type-N connectors carefully to avoid
damage.
Type-N connectors differ from other connector types in that the outer conductor
mating plane is offset from the mating plane of the center conductors. The outer
conductor sleeve in the male connector extends in front of the shoulder of the male
contact pin. When the connection is made, this outer conductor sleeve fits into a
recess in the female outer conductor behind the tip of the female contact fingers
(Figure D-5).
Figure D-5 Type-N connectors
Therefore the mechanical specifications of Type-N connectors give a maximum
protrusion of the female contact fingers
in front of the outer conductor mating plane
and a minimum recession of the shoulder of the male contact pin behind the outer
