Abstract

A coaxial cable connector includes a connector body and a post member disposed within the connector body. A coupling nut is threadingly attached to the post member wherein a flanged portion of the post member provides an axial biasing force with regard to an attached interface port. In one version, the flanged portion is slotted.

Claims

1. A coaxial cable connector comprising:

a connector body having a first end, an opposing second end, and defining a central passageway extending therethrough along an axis;

a post member having a first end and a second end, the post member second end being disposed within the connector body and the post member first end including a flanged portion, at least a portion of the flanged portion configured to provide a biasing force along the axis; and

a coupling nut rotatably attached to the first end of the post member.

2. A connector as recited in claim 1, wherein the flanged portion of the post member includes a helical slot to provide the axial biasing force.

3. A connector as recited in claim 1, wherein the flanged portion of the post member includes an angled slot to provide the axial biasing force.

4. A connector as recited in claim 3, wherein a radial face of the flanged portion of the post member is angled with respect to a plane perpendicular to the axis.

5. A connector as recited in claim 4, wherein the radial face is parallel to the angle of the slot.

6. A connector as recited in claim 1, wherein each of the post member and the port are made from electrically conductive materials.

7. A connector as recited in claim 1, wherein the connector is an F-type connector.

8. A coaxial cable connector, the connector comprising:

a connector body having a hollow interior along an axis;

a post member having a first end and a second end, the first end including a flanged portion being axially and elastically compressible, the second end being disposed within the connector body and axially secured thereto; and

a coupling nut rotatably secured and in overlaying relation to the first end of the post member.

9. A connector as recited in claim 8, wherein the flanged portion of the post member includes at least one angled slot.

10. A connector as recited in claim 8, wherein the connector is an F-type connector.

11. A connector as recited in claim 8, wherein the flanged portion of the post member includes a radial face, the face being angled parallel to the angle of the formed slot.

12. A connector as recited in claim 8, wherein the slot is helical.

13. A connector as recited in claim 8, wherein the slot is spiral.

14. A method of manufacturing a coaxial cable connector that permits electrical continuity between an interface port and the connector to be maintained during the entirety of an attachment procedure with the interface port, the method comprising the steps of:

providing a hollow connector body;

rotatably attaching a nut in relation to one end of the connector body;

providing a post member within the connector body, the post member having a first end positioned within the nut and a second end extending into the interior of the connector body and axially secured therewith, the first end of the post member having a flanged portion; and

forming a slot in the flanged portion of the post member, the flanged portion being made from a spring material, the flanged portion having an angled face wherein the angled face is axially biased into a first position;

wherein an interface port can be attached to the connector through threading engagement between the port and the nut causing the angled face and the slot of the flanged portion to be compressed to a second position and in which the axial biasing force of the flanged portion maintains electrical continuity between the post member and the interface port even when the nut is loosened from a fully tightened condition.
