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. The bridge may be in the form of a metal ring, or similar material, with a cone-like shape and may include a gap to provide resiliency.

Claims

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

a post and an electrically conductive nut, the post surrounded at least in part by an electrically conductive body;

the nut encircles a post end flange and the nut receives a forward mouth of the connector body;

an electrically conductive bridge having a cone-like 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 a nut inner wall; 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 configured as a spring to press against a peripheral wall of the nut.

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

4. A method of shielding a male F-Type connector comprising the steps of:

providing a post with a flanged end and a nut encircling the flange;

an electrically conductive connector body surrounding at least a portion of the post;

a connector body end extending into a gap between the nut and the post;

providing a electrically conductive bridge having a cone-like shape and a centerline about coincident with a central axis of the connector; and

,

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

5. The shielding method of claim 4 further comprising the step of configuring the bridge as a spring to press against a peripheral wall of the nut.

6. The shielding method of claim 5 further comprising the steps of:

configuring the bridge as a partial ring with a gap; and

,

configuring the bridge to grip the forward mouth of the connector body.
