  • Publication number: 20250062532
    Abstract: An antenna structure is disposed on a metal unit and includes a first slot, a second slot, a grounding portion and a short-circuiting portion. The first slot is formed on the metal unit along an axis direction and configured to receive a signal feed. The second slot is formed on the metal unit along the axis direction and separated from the first slot by a distance along the axis direction. The grounding portion is coupled to the metal unit. The short-circuiting portion crosses the second slot and is coupled to the grounding portion.

  • Publication number: 20150229075
    Abstract: An electrical plug connector includes a connector body including a base member, a terminal holder, conducting terminals, a cable, a mount and a metal shield, a springy positioning member positioned in the mount and including a base plate, two hooks and a pressure plate, a slide shell slidably mounted around the connector body and having a front push-pull bar and compression springs set between the connector body and the slide shell. When moving the slide shell to disconnect the electrical plug connector from the connected mating electrical socket connector, the push-pull bar of the slide shell is moved over the pressure plate of the springy positioning member to disengage the hooks of the base plate from the respective hook holes of the metal shield of the mating electrical socket connector. Thus, the user can remove the electrical plug connector from the mating electrical socket connector with one single hand in one single operation step conveniently with less effort.
