  • Patent number: 8171629
    Abstract: Coaxial connectors include a connector body and an inner contact post. A compression sleeve is also provided that is configured to impart a generally circumferential compressive force to secure one or more elements of a coaxial cable between the connector body and the inner contact post when the compression sleeve is in a seated position. The compression sleeve or the connector body includes a first disengagement mechanism that is configured to assist moving the compression sleeve from the seated position to an unseated position in which at least some of the circumferential compressive force is eliminated.
