Abstract

A connector comprising a connector body having a first end and a second end, the connector body configured to receive a prepared coaxial cable, the prepared coaxial cable including an outer conductor and a center conductor, a clamp disposed within the connector body, the clamp including an internally threaded portion and a ramped surface, wherein the clamp threadably engages the prepared coaxial cable, a moveable ramped component disposed within the connector body, the moveable ramped component including an internally ramped surface, and a compression member configured for axial movable engagement with the connector body, wherein, upon axial compression of the compression member, the outer conductor flares out and is pressed between the ramped surface of the clamp and the internally ramped surface of the moveable ramped component is provided. Furthermore, a clamp and an associated method are also provided.

Claims

1. A connector comprising:

a first moveable compression surface disposed within a connector body, wherein the first compression surface is a ramped surface of a clamp, the clamp including an internally threaded portion configured to threadably engage a cable jacket of a coaxial cable; and

a second moveable compression surface disposed within a connector body, the second moveable compression surface configured to cooperate with the first moveable compression surface;

wherein the first moveable compression surface and the second moveable compression surface clamp a flared out portion of the outer conductor of the coaxial cable upon slidable axial compression, and

wherein the slidable axial compression irreversibly engages the outer and center conductors of the coaxial cable.

2. The connector of claim 1, wherein the slidable axial compression is delivered by slidable axial compression of a compression member insertable within or over the connector body.

3. A connector comprising:

a connector body having a first end and a second end, the connector body configured to receive a prepared coaxial cable, the prepared coaxial cable including an outer conductor and a center conductor;

a clamp disposed within the connector body, the clamp including an internally threaded portion and a ramped surface, wherein the clamp threadably engages the prepared coaxial cable;

a moveable ramped component disposed within the connector body, the moveable ramped component including an internally ramped surface; and

a compression member configured for axial movable engagement with the connector body;

wherein, upon axial compression of the compression member, the outer conductor flares out and is pressed between the ramped surface of the clamp and the internally ramped surface of the moveable ramped component, and

wherein the center and the outer conductors are irreversibly seized by the axial compression of the compression member.

4. The connector of claim 3, further comprising:

an electrical contact having a socket, the socket disposed within the connector body and configured to receive the center conductor of the coaxial cable; and

an insulator body disposed within the connector body, the insulator body having a first end and a second end; and

an insert disposed within the connector body to electrically isolate the outer conductor and the center conductor.

5. The connector of claim 3, wherein a collar is disposed proximate the clamp to form a seal around the coaxial cable.
