  • Patent number: 7524205
    Abstract: The present invention is related to a conducting wire anti-drop structure for fixing two mutually connected conducting wires, which respectively have a connecting terminal for connecting with each other. The conducting wire anti-drop structure is characterized in that a positioning device is mounted on the connecting terminal of one of the conducting wires and has a positioning portion. The positioning portion is used to connect with a position-limiting device, which has an engaging portion extended from the connecting terminal for engaging with the other connecting terminal so as to limit the connection between the connecting terminals and provide stability.

  • Patent number: 7254020
    Abstract: The present invention discloses a fan assembly for a power supply and improves the traditional installation of a fan onto a power supply that leaves insufficient spaces for designing the connecting holes as required by the existing installation specification, and mounts the fan into a power supply at a specific position by a specific fixing member and uses the fixing member to keep the fan at a specific interval from the end surface of the power supply without being in direct contact with the power supply. Therefore, the interval from the end surface provides sufficient space for the design of the ventilation holes for the airflow and the connecting holes as required by the installation specification of the power supply.
