  • Patent number: 10044150
    Abstract: Previously available elastomeric EMI gaskets provided for multiport RF connector assemblies have performance limiting drawbacks. Consequently, EM isolation provided by a previously available elastomeric EMI gasket is often inadequate. Various implementations disclosed herein include multiport RF connection arrangements that use a metal gasket arranged within at least a portion of an isolation space provided by a multiport RF connector. In some implementations, a multiport connection arrangement includes a substrate, a multiport RF connector and a fitted metal gasket. The substrate includes a first surface and a first plurality of connection ports. The multiport connector has a body that includes a second surface, a second plurality of connection ports, and includes an electromagnetic isolation boundary that defines an isolation space between at least two of the second plurality of connection ports terminating at the second surface.

  • Patent number: 9979128
    Abstract: Previously available multiport connector pairings that use floating devices typically include relatively generous lead-in chamfers surrounding receiving ports in order to facilitate blind mating. As port density increases there is less room for lead-in chamfers, and in turn, blind mating becomes more challenging. By contrast, various implementations disclosed herein include multiport connection arrangements that include a floating connection device at least partially included within a port, and a radial centering mechanism arranged in combination with the floating connection device. The radial centering mechanism imparts a force that biases the floating connection device along the axis of the port. In some implementations, the radial centering mechanism imparts a substantially balanced axial force in order to bias the floating connection device. In some implementations, the radial centering mechanism imparts a substantially radial force in order to bias the floating connection device.

  • Patent number: 7927125
    Abstract: A robust multi-port front panel RF (radio frequency) connector system design using a single lead screw is provided. The system allows for individual connector removal from the header while installed. Additionally, the system employs a user applied torque limiting feature for robustness. This individual connector removal can be provided by way of a slider bar which retains cables in place when in the ‘closed’ or ‘locked’ position.
