RF connectors having ground springs
First Claim
1. An RF connector suitable for use in combination with a hermetically sealed lightweight electronics housing package, said RF connector comprising:
- (a) a first metal layer bonded to a second metal layer;
(b) a hermetic feedthru comprising a ferrule member, a dielectric member, and a pin member, wherein said dielectric member comprises a channel to receive a first end of said pin member and wherein said ferrule member is fabricated to receive said dielectric member; and
(c) a ground spring,wherein said ground spring forms a plurality of first circumferential contacts with said ferrule member and a plurality of second circumferential contacts with said electronics housing or package, thereby forming a conductive ground path between said hermetic feedthru of said RF connector and said electronics housing or package, said electronics housing or package comprising a dielectric to receive a second end of said pin member.

Abstract
Radio frequency (RF) connectors and electronics housings and packages employing one or more inventive RF connector(s) provided herein utilize a ground spring to achieve improved conductivity of the ground signal by making a plurality of contacts with a ferrule member of the RF connector'"'"'s hermetic feedthru and a plurality of contacts with the electronics housing or package at points adjacent to an air dielectric. Ground springs used in connection with the present RF connectors maintain predetermined spring properties under compression and/or extreme environmental conditions, including thermal fluctuations, and therefore may be suitably employed in aircraft and spacecraft.
