Abstract: An electrical terminal has a soldering plate, a propping plate extending upward and rearward from a front end of the soldering plate, a resilient arm bending upward and then extending forward from a rear end of the soldering plate, and a pressing portion of inverted-V shape connected with a front end of the resilient arm and defining a mouth between a front arm and a rear arm thereof. A top end of the propping plate bends forward and downward to form a lower hook tail stretched in the mouth, resisting against an inner side of the front arm, and apart from an inner turning of the pressing portion. A bottom end of the front arm bends rearward and upward to form an upper hook tail hooking the lower hook tail with a free end thereof resisting against an outer side of the propping plate.

Abstract: This invention is a ground flutter testing system without a wind tunnel, called Dry Wind Tunnel (DWT) System. The DWT system consists of a Ground Vibration Test (GVT) hardware system, a multiple input multiple output (MIMO) force controller software, and a real-time unsteady aerodynamic force generation software, that is developed from an aerodynamic reduced order model (ROM). The ground flutter test using the DWT System operates on a real structural model, therefore no scaled-down structural model, which is required by the conventional wind tunnel flutter test, is involved. Furthermore, the impact of the structural nonlinearities on the aeroelastic stability can be included automatically. Moreover, the aeroservoelastic characteristics of the aircraft can be easily measured by simply including the flight control system in-the-loop. In addition, the unsteady aerodynamics generated computationally is interference-free from the wind tunnel walls.

Abstract: A lens module socket includes an insulating housing, a plurality of conductive terminals, an inner shielding shell and an outer shielding shell. The insulating housing has an accommodating space therein for receiving the lens module and a plurality of buckling grooves distributed at outsides of corresponding side walls thereof.

A free end of the flexible arm is arched upward to form an inverted-V shaped contacting portion adjacent to the bracket plate. Two ends of a distal edge of the contacting portion further extend beyond the two opposite side edges of the bracket plate to form a pair of resisting tails respectively restrained under the blocking ears.
