1. An F-type coaxial cable connector comprising:
- a connector body, having a first end and a second end;
a post, attached to the connector body;
a threaded nut, rotatable with respect to the post and also axially movable with respect to the connector body between a first position and a second position;
a biasing member, internally located axially and radially within the nut, the biasing member compressably operable to exert force on the nut tending the nut to move in a direction toward the second end of the connector body; and
a joint stop element, located to operably interact with the biasing member and introduce obstructive structure that impedes axial movement of the nut;
wherein the nut is movable in an axial direction toward the first end of the connector body when in a first position; and
wherein when the nut is located in a second position it is no longer movable in a direction toward the first end of the connector body, because the obstructive structure of the joint stop element physically impedes further movement of the nut.

16. An F-type coaxial cable connector for coupling a coaxial cable to an interface port, the coaxial cable including a center conductor surrounded by a dielectric material, the dielectric material being surrounded by an outer conductive grounding shield, the outer conductive grounding shield surrounded by a protective outer jacket, the F-type coaxial cable connector comprising in combination:
-
a connector body, having a first end and a second end, the second end configured to deformably compress against and seal a received coaxial cable; a post, axially securely attached to the connector body, the post having a first end and a second end, the first end of the post including a flange and the second end of the post configured to be inserted into an end of the received coaxial cable around the dielectric and under at least one layer of the conductive grounding shield thereof; a threaded nut, rotatable with respect to the post and also axially movable with respect to the connector body between a first position and a second position; a biasing member, the biasing member compressably operable to exert force on the nut tending the nut to move in a direction toward the second end of the connector body; a fastener member, including an internal ramped surface, the fastener member operable to deformably compress the outer surface of the connector body to axially secure the received coaxial cable between the connector body and the fastener member; and a joint stop element, including obstructive structure of a component of the connector that is axially movable with respect to the received and secured cable and including obstructive structure of a component that is not movable with respect to the received and secured cable; wherein the obstructive structure of the movable component with respect to the cable contacts the obstructive structure of the non-axially-movable component with respect to the cable when the nut is in a second position to impede axial movement of the nut in a direction toward the first end of the connector body. - View Dependent Claims (17, 18, 19, 20, 21)

22. A coaxial cable connector comprising:
-
a connector body; a post, attached to the connector body; a threaded nut, rotatable with respect to the post and also axially movable with respect to the connector body between a first position and a second position; a biasing member, operable to exert force on the nut to move the nut; and means for impeding axial movement of the nut in one axial direction, when the nut resides in the second position; wherein the means remain structurally sound during the buildup of axial force applied thereto, as threadable rotational torque is exerted when the nut is tightened into mating with a corresponding interface port, through operation of a wrench; and wherein the means prevent the connector from experiencing structural and functional deformation because the movement impediments of the means prevent the biasing member from being over-compressed causing connector components to yield and thus not properly function during repetitive use.

23. A method of extending an RF grounding shield from a coaxial cable to a cable interface port, the method comprising:
-
providing an F-type coaxial cable connector to connect the coaxial cable to the interface port, the F-type coaxial cable connector comprising; a connector body, having a first end and a second end; a post, attached to the connector body and operable to receive the coaxial cable; a threaded nut, rotatable with respect to the post and also axially movable with respect to the connector body between a first position and a second position; a biasing member, operable to exert force on the nut tending the nut to move in a direction toward the second end of the connector body; and a joint stop element, located to interact with the biasing member and introduce obstructive structure that impedes axial movement of the nut; wherein the nut is movable in an axial direction toward the first end of the connector body when in a first position; and wherein when the nut is located in a second position it is no longer movable in a direction toward the first end of the connector body, because the obstructive structure of the joint stop element physically impedes further movement of the nut; rotating the nut to thread the nut onto the interface port a distance sufficient for the post of the connector to contact the port, wherein the position of the connector structure when the post initially contacts the port corresponds to a first position; advancing and tightening the nut further onto the port to ensure electrical contact between a mating edge of the port and a mating edge of the post, wherein, as the nut advances onto the port it axially slidably moves with respect to the post and connector body in a direction toward the first end of the connector body, so that the associated biasing member exerts resultant force to drive the post into firm contact with the interface port; and impeding further axial movement of the nut with respect to the post and the connector body, by bottoming out the movement of the nut through operation of obstructive structure of the joint stop element so that the bottoming out of the movement of the nut corresponds to a second position, wherein the nut is no longer axially movable in a direction toward the first end of the connector body. - View Dependent Claims (24, 25, 26, 27, 28)
