Abstract

A male F-Type coaxial cable connector has an improved RF shield including a bridge located between and electrically interconnecting a connector fastening nut and a connector body portion.

Claims

1. An improved male F-Type connector radio frequency shield comprising:

a post and an electrically conductive nut, the post substantially surrounded by an electrically conductive body;

a nut partition separates a nut rear cavity and a nut forward cavity, the nut rear cavity bounded at least in part by a nut overhang;

the nut forward cavity encircles a flange at one end of the post and the nut rear cavity receives a forward mouth of the connector body;

an electrically conductive bridge having a frustoconical shape and a centerline about coincident with a central axis of the connector;

the bridge interposed between the forward mouth of the connector body and the nut overhang; and

,

the bridge mechanically contacting and thereby electrically interconnecting the nut and the connector body.

2. The connector of claim 1 wherein the bridge is operable as a spring to press against a peripheral wall of the nut rear cavity.

3. The connector of claim 2 wherein the bridge is in the form of a partial ring with a gap and the bridge is operable as a spring to grip the forward mouth of the connector body.

4. The connector of claim 3 wherein the nut partition and the forward mouth of the connector body prevent the bridge from contacting the flange and the post.

5. The connector of claim 4 wherein the bridge has a “

V”

shaped cross-section.

6. The connector of claim 5 where the bridge is made from a resilient material.

7. The connector of claim 6 wherein the bridge is made from stainless steel.
