Definitions

  • Connectors for coaxial cables are typically connected onto complementary interface ports to electrically integrate coaxial cables to various electronic devices.
  • Push-on connectors have been used by consumers for their ease of use, however, over time, such connectors do not remain properly attached to the interface port. For example, push-on connectors can slip off the port if sufficient friction is not maintained between the connector and the port. Such friction forces are a function of the manufacturing tolerances which must be maintained during fabrication. It will be appreciated that it is difficult and/or costly to produce a friction fit, push-on connector which generates sufficient friction between the interface surface of the connector and the external threads of the port.
  • conventional, threaded connectors can provide a sufficient retention force, up to the yield strength of a coaxial cable; however, conventional, threaded connectors must also be fully and carefully rotated onto the port during installation. Furthermore, it is desirable to maintain electrical continuity through a coaxial cable connector. This typically involves a creation of a continuous electrical path across the conductive components of the connector and the interface port to maintain a reliable ground connection and an efficient RF shield.
