Coaxial cable coupling nut
View Patent ↗A hybrid coupling nut for a cable connector includes a plurality of fingers on a friction sleeve portion of the nut with a plurality of threads adjacent the fingers inside the nut. An annular knurled portion on the nut adjacent the fingers on the outside of the nut assist a user in connecting the nut to an RF port. Each finger includes a beveled edge. The nut also includes an annular flange for rotatably connecting the coupling nut to the cable connector.
1. A cable connector for connecting a coaxial cable onto a port, wherein the cable connector consists of a coupling nut and a remainder part, comprising:
the nut including
a friction sleeve portion at a front end of the nut;
the friction sleeve portion including a smooth portion on an inside of the nut;
a threaded portion on an inside of the nut adjacent the smooth portion, a rear portion of the nut being connected at a front end of the remainder part; and
a plurality of slots parallel to a longitudinal axis of the nut, wherein the plurality of slots define a plurality of fingers in the friction sleeve portion;
wherein, when the nut is connected onto the port, both the friction sleeve portion and the threaded portion make electrical and physical contact with the port; and
wherein an end of each finger includes a beveled edge.
2. A coupling nut according to claim 1 , further comprising a knurled portion on an outside of the nut at an end of the nut opposite an end of the nut containing the plurality of fingers.
3. A coupling nut according to claim 1 , further comprising means for rotatably connecting the coupling nut to a cable connector.
4. A method of manufacturing a cable connector for connecting a coaxial cable onto a port, wherein the cable connector consists of a coupling nut and a remainder part, comprising the steps of:
forming the coupling nut and forming the remainder portion;
attaching a rear portion of the coupling nut to a front end of the remainder part;
forming a friction sleeve portion of the nut which includes a smooth portion on an inside of the nut;
forming a threaded portion on an inside of the nut adjacent the smooth portion; and
forming a plurality of slots parallel to a longitudinal axis of the nut, wherein the plurality of slots define a plurality of fingers in the friction sleeve portion of the nut;
forming a beveled edge on an end of each finger;
wherein, when the nut is connected onto the port, both the friction sleeve portion and the threaded portion make electrical and physical contact with the port.
5. A method according to claim 4 , further comprising the step of forming a knurled portion on an outside of the nut at an end of the nut opposite an end of the nut containing the plurality of fingers.
6. A method according to claim 4 , further comprising forming an annular flange on the nut for rotatably connecting the coupling nut to a cable connector.
