Abstract: A hinge antenna comprises a major conductor, a first rotating element and a second rotating element. The stretching arms on both sides of the major conductor are assembled to the first rotating element and the second rotating element, respectively. The first rotating element further comprises a torque device and a first vice conductor, and the second rotating element further comprises a signal feeding line, a connection device, and a second vice conductor. The signal feeding line is electrically connected to the connection device and the second vice conductor, by which a high frequency signal can be passed to the major conductor, and then passed to the torque device on the other side and the first vice conductor. The aforementioned configuration is utilized to form an antenna loop. In addition, the configuration of this antenna can be applied to a foldable electronic device.

Abstract: The present device is a Universal Serial Bus (USB) connector which includes a first terminal set and a second terminal set. By increasing the width of a connection portion of a ground terminal of the second terminal set, and bending two pairs of the signal terminal within the second terminal set toward one side respectively and surrounding two sides of the ground terminal connecting section so as to let two pairs of the signal terminals away from the signal terminals in the first terminal set so as avoid the crosstalk interference caused by the first pair of the signals terminals in the second pair of the signal terminals and the third pair of the signal terminals to stabilize the transmission.

Abstract: A plug connector is for connecting to a receptacle connector. The receptacle connector comprises two resilient plates. The plug connector has an insulating housing and a metal shell. The insulating housing includes a tongue portion and a base portion for accommodating and connecting the terminals. The metal shell has a top plate, bottom plate, and two side plates. Multiple recesses, protrusions or elongated recesses are selectively formed on at least one of the top plate, the bottom plate for connecting the resilient plates. These can avoid electromagnetic interference, dusts or any external substances from attaching to the insulating house and also ensure a high quality of the insertion force and the extraction force after frequent uses.

Abstract: The present invention discloses a subscriber identity module connector which places a detecting terminal and a grounding terminal into a same contact area. The above placement of the detecting terminal and the grounding terminal form a circuit to determine if a SIM card is inserted appropriately. As a result, there is no need to set conventional detecting unit, and the space of the subscriber identity module connector are advantageously saved. It not only simplifies the placement of circuit board (PCB) and but also reduces the manufacturing cost.
