  • Publication number: 20170045549
    Abstract: The present disclosure discloses a radio frequency test socket, a radio frequency test cable and relates to RF test. The RF test method includes: connecting a first test apparatus to a second test apparatus via a first and second elastic apparatuses in a radio frequency test socket, the first and second elastic apparatuses are connected to the first and second test apparatuses; disconnecting the radio frequency test socket from the second test apparatus by urging an insulated push pin apparatus against the second elastic apparatus, so that the first test apparatus is tested via a radio frequency test plug and the first elastic apparatus; disconnecting the radio frequency test socket from the first test apparatus by urging the insulated push pin apparatus against the first elastic apparatus, so that the second test apparatus is tested via the radio frequency test plug and the second elastic apparatus.

  • Patent number: 9013363
    Abstract: Provided is a method for implementing a terminal antenna, including: welding a metal shell for fixing a side key on a ground of a printed circuit board; dividing the ground of the printed circuit board into a first ground and a second ground, connecting the first ground with the second ground by at least one first isolating unit, the first ground being welded with the metal shell, and a length of the first ground being ¼ of a wavelength of a radio operating frequency band, and connecting the first ground with an antenna receiving/transmitting unit, thereby implementing a terminal antenna by taking the first ground as a radiator. The present invention also provides a corresponding terminal antenna and a terminal thereof.

  • Patent number: 7500661
    Abstract: A self-clamping mechanism includes a first support surface and a clamping member in sliding contact with the first support surface. The clamping member has a first surface in confronting engagement with the first support surface, and a second surface for engaging the surface of an object to be clamped by the mechanism. The first and second surfaces of the clamping member are disposed at a predetermined angle, ?, such that when certain conditions are met, the object will remain clamped by the mechanism regardless of external forces applied to the object.
