Abstract

A coaxial connector comprising a connector body; a nut, axially rotatable with respect to the connector body, the nut having a first forward end configured for threadably attaching to an interface port and a second rearward end; and a continuity member, electrically contacting the nut; wherein the connector is configured to maintain return loss below -40 dBvM when the connector is installed on the interface port, so as to be only engaged with one thread of the interface port is provided.

Claims

1. A coaxial connector comprising:

a connector body;

a nut, axially rotatable with respect to the connector body, the nut having a first forward end configured for threadably attaching to an interface port and a second rearward end; and

a continuity member, electrically contacting the nut;

wherein the connector is configured to maintain return loss below −

40 dBvM when the connector is installed on the interface port, so as to be only engaged with one thread of the interface port.

2. The connector of claim 1, wherein there is no significant electromagnetic ingress into the connector even when the connector is installed on the interface port, so as to be only engaged with one thread of the interface port.

3. A continuity member for extending electromagnetic shielding through a coaxial cable connector, the continuity member comprising:

a first conductive portion, configured to contact a nut of a coaxial connector, wherein the nut includes a first forward end configured for threadably engaging an interface port, and a second rearward end; and

a second conductive portion, configured to contact a conductive component of the coaxial connector, wherein the conductive component of the coaxial connector is rotatable with respect to the nut;

wherein, the continuity member is configured to extend electromagnetic shielding continuity from a coaxial cable through the coaxial connector to the interface port as engaged by the nut, so that the connector maintains return loss below −

40 dBvM when the connector is installed on the interface port while only engaged with one thread of the interface port.
