A coaxial cable connector generally includes a connector body, a nut rotatably coupled to the connector body, a post disposed in the connector body and a biasing element acting between the post and the nut. The nut has an internal thread for engagement with an external thread of a mating connector.
A coaxial cable connector generally includes a connector body, a nut rotatably coupled to the connector body, a post disposed in the connector body and a biasing element acting between the post and the nut. The nut has an internal thread for engagement with an external thread of a mating connector. The internal thread of the nut and the external thread of the mating connector can be mismatched, wherein an interference fit is created therebetween upon connection of the nut to the mating connector. Also, the post can have a forward flanged base portion disposed within the axial length of the internally threaded surface of the nut, which, together with the biasing element, provides a constant force between the post and the nut.

What is claimed is: 1. A coaxial cable connector for coupling a coaxial cable to an external thread of a mating connector, the connector comprising: a connector body having a forward end and a rearward cable receiving end for receiving a cable; a nut rotatably coupled to said forward end of said connector body, said nut having an internally threaded surface for engagement with the external thread of the mating connector, said internally threaded surface having an axial length, an annular post disposed within said connector body, said post having a forward flanged base portion disposed within a rearward extent of said axial length of said internally threaded surface of said nut; and a biasing element acting between said post and said nut. 2. A coaxial cable connector as defined in claim 1, wherein said nut comprises an internal radial flange having a forward facing wall and said flanged base portion of said post includes a rearward facing wall, said forward facing wall of said nut radial flange and said rearward facing wall of said post flanged base portion defining an annular chamber for receiving said biasing element. 3. A coaxial cable connector as defined in claim 2, wherein at least one thread, and no more than three threads, of said nut threaded surface is disposed within said annular chamber rearward of said rearward facing wall of said post flanged base portion. 4. A coaxial cable connector as defined in claim 1, wherein said post comprises a step formed on an outer surface thereof, said step engaging a forward end of said connector body for positioning said post flanged base portion within said axial length of said internally threaded surface of said nut. 5. A coaxial cable connector as defined in claim 1, wherein said flanged base portion of said post has a maximum outer diameter and said internally threaded surface of said nut has a minimal inner diameter, said maximum outer diameter of said post flanged base portion being smaller than said minimal inner diameter of said nut threaded surface, whereby said post flanged base portion is axially movable with respect to said internally threaded surface of said nut. 6. In combination: a connector terminal including a rearward facing wall and an externally threaded surface; and a coaxial cable connector connected to said connector terminal, said coaxial cable connector comprising: a connector body having a forward end and a rearward cable receiving end for receiving a cable; a nut rotatably coupled to said forward end of said connector body, said nut having an internally threaded surface for engagement with said externally threaded surface of said connector terminal, said internally threaded surface having an axial length, an annular post disposed within said connector body, said post having a forward flanged base portion disposed within a rearward extent of said axial length of said internally threaded surface of said nut; and a biasing element acting between said post and said nut to urge a forward facing wall of said post flanged base portion against said rearward facing wall of said connector terminal, wherein said nut is permitted to rotate up to three hundred sixty degrees before said forward facing wall of said post flanged base portion breaks electrical and mechanical contact with said rearward facing wall of said connector terminal. 7. A combination as defined in claim 6, wherein said nut of said connector comprises an internal radial flange having a forward facing wall and said flanged base portion of said post includes a rearward facing wall, said forward facing wall of said nut radial flange and said rearward facing wall of said post flanged base portion defining an annular chamber for receiving said biasing element. 8. A combination as defined in claim 6, wherein at least one thread, and no more than three threads, of said nut threaded surface is disposed within said annular chamber rearward of said rearward facing wall of said post flanged base portion. 9. A combination as defined in claim 6, wherein said post of said connector comprises a step formed on an outer surface thereof, said step engaging a forward end of said connector body for positioning said post flanged base portion within said axial length of said internally threaded surface of said nut. 10. A combination as defined in claim 6, wherein said flanged base portion of said post has a maximum outer diameter and said internally threaded surface of said nut has a minimal inner diameter, said maximum outer diameter of said post flanged base portion being smaller than said minimal inner diameter of said nut threaded surface, whereby said post flanged base portion is axially movable with respect to said internally threaded surface of said nut. 11. A method for reducing the tendency of a coaxial cable connector to loosen itself from a device port, the method comprising the steps of: providing a device port with a rearward facing wall and an externally threaded surface; providing a coaxial cable connector with a connector body and a nut rotatably coupled to the connector body, said nut having an internally threaded surface with an axial length; providing an annular post disposed within said connector body, said post having a forward flanged base portion disposed within a rearward extent of said axial length of said internally threaded surface of said nut; providing a biasing element acting between said post and said nut; and connecting said connector nut with said device port by rotating said nut in a first direction thereby engaging said externally threaded surface of said port with said internally threaded surface of said connector nut, whereby said biasing element urges said forward facing wall of said post flanged base portion against said rearward facing wall of said port device, whereby said nut is permitted to rotate in a reverse direction up to three hundred sixty degrees before said forward facing wall of said post flanged base portion breaks contact with said rearward facing wall of said port device. 12. A method as defined in claim 11, wherein said biasing element is selected from the group consisting of compression springs, wave springs, conical spring washers, Belleville washers and compressible O-rings.
