Abstract: The present invention discloses a latching structure of a connector, to make the connector and the mating connector achieve a perfect latching effect by providing a resilient latching member in the connector. The resilient latching member is a one-piece construction comprising a base portion and a spring portion, the spring portion has a pressing portion, a plurality of extending portions and latching hooks, the base portion has clasping portions fixed inside the connector making the spring portion become a movable free end, the extending portions and the clasping hooks could be shifted jointly by use of the pushing portion of the plastic cover pressing the pressing portion, making the clasping hooks change positions.

Abstract: Provided is an ultra-wideband dipole antenna. In one embodiment, the antenna comprises a first outer sleeve, an intermediate sleeve surrounded by the first outer sleeve, a second outer sleeve above the first outer sleeve, a conductive interconnection interconnected the outer sleeves, and an inner coaxial conductor surrounded by the intermediate sleeve. A distance between the first outer sleeve and the intermediate sleeve can be changed for adjusting the generated capacitance for obtaining a required impedance matching in the resonance mode of an antenna operating bandwidth and an ultra-wideband characteristic. The antenna is particularly suitable for operating in a frequency range of 2.1 GHz to 11.7 GHz.
