Abstract

The coaxial cable connector has a coupler, a post, and a ring that prevent interfaces from gapping and provide a robust alternative ground path that also RF shields the connector from both ingress and egress. The ring is disposed in between and engages at least a portion of a groove in the body and at least a portion of the channel in the coupler, radial movement of the coupler causes the axial movement of the body relative to the terminal.

Claims

1. A coaxial cable connector for coupling an end of a coaxial cable to a terminal, the coaxial cable connector comprising:

a body, the body comprising a rear end, a front end, an external surface, and an internal surface extending between the rear and front ends of the body, the external surface having a groove, the front end of the body having fingers biased radially inward to engage a portion of the terminal;

a coupler disposed proximate the front end of the body, the coupler having a front end and a back end and an opening extending therebetween, the opening having an internal surface and a channel in the internal surface, the opening receiving at least a portion of the body; and

a ring having a forward facing surface and a rearward facing surface, the ring disposed in and engaging at least a portion of the groove in the body and at least a portion of the channel in the coupler, wherein rotational movement of the coupler causes the axial movement of the body relative to the terminal.

2. The coaxial cable connector according to claim 1, further comprising a threaded member disposed in the opening of the coupler, the threaded member axially movable relative to the coupler and elastically biased against the front end of the body, the threaded member having a threaded opening to engage a corresponding threaded portion of the terminal.

3. The coaxial cable connector according to claim 2, further comprising an elastic ring disposed between the threaded member and the front end of the body to elastically bias the threaded member toward the body.

4. The coaxial cable connector according to claim 2, wherein the internal surface of coupler engages at least a portion of an outer surface of the threaded member, wherein rotation of the coupler about the body causes rotation of the threaded member.

5. The coaxial cable connector according to claim 1, further comprising a sealing member disposed between the coupler and the body.

6. The coaxial cable connector according to claim 1, the internal surface of the coupler having a threaded portion to engage a corresponding threaded portion on a terminal.

7. The coaxial cable connector according to claim 6, wherein rotation of the coupler when engaging a terminal draws the terminal into physical and electrical contact with the body.
