  • Publication number: 20190204518
    Abstract: The present invention provides a fiber transmission device including a fiber optic connector, a receiver, and a control circuit board; wherein an optical fiber core is set inside the fiber optic connector; and the receiver sets a plurality of pins. The control circuit board is electrically connected with the plural pins of the receiver. A first signal, such as the optical signal, received by the receiver is transformed into a second signal, such as the electric signal, and then output to the control circuit board through the pins, and then the control circuit board is electrically connected with the transmission line having a signal connector, such as a USB Type-C connector, an HDMI connector, . . . , etc. Thus, achieving that the optical signal can be directly transformed into the electric signal and output the signal through the transmission line and the signal connector which does not need a conventional external signal adapter.

  • Patent number: 9935380
    Abstract: The antenna device includes a first antenna module and a second antenna module. The first antenna module includes a number of first antennas disposed at intervals. The second antenna module includes a number of second antennas disposed at intervals within a space surrounded by the first antennas. The first and second antennas are of different polarization directions. In one embodiment, the first antennas are horizontally polarized antennas having omnidirectional field patterns. The second antennas are inverted F antennas. By arranging the first and second antennas along an outer ring and an inner ring respectively, the distance between the first and second antenna modules are maximized. Furthermore, by having the first and second antennas with orthogonal polarization directions, the mutual interference between the radiation energy of the first and second antenna modules is effectively reduced.

  • Patent number: 8840419
    Abstract: A communication connector comprises a connector body and a tab operating mechanism. The connector body has a locking tab at a front top portion thereof and is fitted to a case at a rear portion thereof, wherein the case is provided with a pivot portion. The tab operating mechanism includes a press member and spring means. The press member is pivotally mounted to the pivot portion of the case. The spring means is disposed between the case and the locking tab for engaging with the locking tab from a lower position. With the present invention, the spring means can assist the locking tab 11 to return to its normal position, while the press member can limit the locking tab within an angle for protecting the locking tab from being overly bent by improper external force. Such features make the present invention a robust and reliable communication connector.

  • Patent number: 7396250
    Abstract: The plugging device of the present invention provides a pair of sticks similar to the blades of a scissor on top of the connector of the plugging device. The pair of sticks is closed together when they are plugged into a network socket along with the connector. Then, by twisting a knob of the plugging device behind the connector, the two sticks are opened so that the hooks at the front ends of the sticks lock to the network socket for reliable connection. To unplug, the knob is twisted in a reversed direction and the two sticks are closed together again so that they are free to be pulled out of the network socket along with the connector.
