  • Patent number: 8106323
    Abstract: A potential switching apparatus for a power adapter which transforms input power to output power delivered through a power output cord. The potential switch apparatus switches the potential of the output power. It includes a first body and a second body located on the power output cord. The first body has a first contact and a second contact. The second body has a switch element connectable to the first contact to deliver the output power at a first potential and connectable to the second contact to deliver the output power at a second potential. Thus the potential of the output power can be switched. The present invention improves the conventional potential switch device on the power adapter that is too bulky in size.

  • Publication number: 20100062652
    Abstract: A power adapter with a changeable plug includes a positioning surface and an electric connecting surface connected to an edge of the positioning surface. The plug has a positioning plate and an electric connecting plate corresponding to the positioning surface and the electric connecting surface. The electric connecting surface and the electric connecting plate have a first socket and a second socket, and the plug has a transmission terminal electrically connected to the second socket, such that the power adapter and the plug are disposed on different distal surface through the positioning surface and the electric connecting surface as well as the positioning plate and the electric connecting plate to improve the shortcomings of traditional power adapters having a poor contact when conducting components are worn out or damaged in a process of installing or removing the plug, so as to improve the quality of power transmission.

  • Publication number: 20090168400
    Abstract: In a light emitting frame and a heat dissipating fan using the light emitting frame, a light emitting element can be installed freely on the heat dissipating fan by a detachable light emitting frame composed of a separate main frame body, and the main frame body has a limit position portion passed through by a same fixing element, such that when the heat dissipating fan is installed to an electronic device, the light emitting frame is fixed. The invention overcomes the shortcomings of a prior art design of integrating the light emitting element with the heat dissipating element. In addition to lowering the manufacturing cost, the invention provides a number of selections for the material of the light emitting element and the light projecting angle.
