Abstract

A cable connector configured to couple a cable to another connector or piece of video or audio equipment may include a connector body, a nut, an annular post and a biasing element. The connector body may include a forward end and a rearward end, where the forward end is configured to connect to the second connector and the rearward end is configured to receive a coaxial cable. The nut may be rotatably coupled to the forward end of the connector body and the annular post may be disposed within the connector body. The annular post may also include an annular notch located at the forward end of the connector body. The biasing element may be located in the annular notch.

an end cap having a body and a forward flanged portion, wherein the end cap is movable in an axial direction relative to the post; and

a biasing element, between the end cap and the post, for biasing the end toward a connector port.

9. The coaxial cable connector of claim 8, wherein the biasing element is press fit between the end cap and the post.

10. The coaxial cable connector of claim 8, wherein the nut includes an inwardly directed flange that engages the annular post and retains the nut in an axially fixed position relative to the annular post.

11. The coaxial cable connector of claim 8, wherein the biasing element comprises a compression spring, a wave spring, a conical spring washer, a Belleville washer, or a compressible resilient elastomeric element or material.

12. The coaxial cable connector of claim 8, wherein the end cap is electrically conductive.

13. A coaxial cable connector for coupling a coaxial cable to a mating connector, the coaxial cable connector comprising:
