Flexible RF seal for coaxial cable connector
First Claim
1. A coaxial cable connector for mounting on a RF port comprising:
- a body member having an internal passageway defined along a longitudinal axis of the body member;
a post member having a flange end and a substantially cylindrical bore therethrough, the post member partially disposed within the internal passageway;
a nut having a first nut end with inner threading and a second nut end with a flange to engage the flange end of the post; and
,a flexible RF seal comprising;
a tubular insert at one end;
a flexible brim at an opposing end; and
, a transition band between the tubular insert and the flexible brim, wherein the tubular insert is configured to engage the flange end of the post and the transition band is configured to angle the flexible brim inward toward the longitudinal axis, whereby tightening the connector to the port causes the port to deform the flexible brim against the flange end of the post.

Abstract
The present invention incorporates a flexible seal into a typical coaxial cable connector. The seal comprises a flexible brim, a transition band, and a tubular insert with an insert chamber defined within the seal. In a first embodiment the flexible brim is angled away from the insert chamber, and in a second embodiment the flexible brim is angled inward toward the insert chamber. A flange end of the seal makes a compliant contact between the port and connector faces when the nut of a connector is partially tightened, and becomes sandwiched firmly between the ground surfaces when the nut is properly tightened. The present invention allows the connector to make a uniform RF seal on a port even with a range of tightening torques.
