  • Patent number: 10020613
    Abstract: A power terminal includes a terminal beam having a mating surface. A protective thermal coupler bridge is positioned adjacent the terminal beam having a bridge conductor, an insulating substrate and a bridge pad. The bridge pad has a mating surface. A variable resistive member is electrically coupled between the terminal beam and the bridge conductor to provide a shunt so that arcing does not occur when the power terminal is disconnected from the mating power terminal. The mating surface of the terminal beam is separable before the mating surface of the bridge pad is disconnected so that the resistance in the variable resistive member increases after disconnection of the main power terminal from the mating power terminal and prior to disconnection of the bridge pad from the mating power terminal to shunt the current through the bridge conductor and the variable resistive member during unmating.

  • Patent number: 9954264
    Abstract: A cavity filter and a RF communication device including the cavity filter are disclosed. The cavity filter includes a cavity body, a cover plate, a resonance rod, a tuning screw, and a supporting member. The cover plate caps the cavity body to form a resonance cavity. The resonance rod is a tube with an opening at one end, where the opening end is combined with the cover plate or the cavity body. The supporting member is mounted to the cover plate or the cavity body to further secure the tuning screw to the resonance rod, and pushes the tuning screw along an axial direction of the resonance rod against the bottom end of the resonance rod, so as to make the resonance rod undergo an elastic deformation and thus adjust the RF parameters of the cavity filter.
