  • Publication number: 20080227338
    Abstract: A portable adapter includes a first body; a second body; a pivoting unit, mounted between the first body and the second body; a power input, mounted on the first body; a power output, mounted on the first body near to the pivoting unit; and at least one connector, mounted on the second body. The pivoting unit unfolds the first body and the second body in a manner such that the power output is partially hidden between the first body and the second body. The foldable structure of the portable adapter has a reduced volume and the power output is partially hidden during travel. When in use with a laptop, the first body and the second body unfold to an angle of 90 degrees relative to each other by means of the pivoting unit, so that the connector can be plugged with an electronic device.

  • Patent number: 7374425
    Abstract: A foldable power supply device includes a first socket, a second socket, and a pivoting unit. The first socket has multiple sets of first plugging holes and first conductive plates. The second socket has multiple sets of second plugging holes and second conductive plates. The pivoting unit is located between the first socket and the second socket. The direction of the rotation shaft of the pivoting unit is not parallel to the plugging direction of the first plugging holes and the second plugging holes. Thereby, the foldable power supply device can be opened into a block type to lower its height and be used as a multi-hole type. Alternatively, the device can also be folded to become a vertical type so that one side of the device can align with the wall, and the plugs or the transformers can be plugged into the device in two face-to-face directions.

  • Patent number: 7311533
    Abstract: A light socket structure includes a main body, a plug, a switch control element, and sockets. The plug is movably jointed with the main body. The switch control element is disposed on the main body for controlling the plug to be accommodated within or exposed out from the main body. The sockets are disposed in the main body, and each socket is electrically connected with the plug. In other words, when a user wants to use the light socket structure, he/she can control (by pressing or pulling) the switch control element to expose the plug's conductive terminals out from the main body. When the user does not want to use the light socket structure, he/she can manually push the plug's conductive terminals to return into the main body.

  • Patent number: 6935878
    Abstract: The present invention discloses a link assembly for connectors, which comprises a main body, a live terminal, a neutral terminal, a ground terminal, and a push rod. The live terminal and the neutral terminal are bent directly under two wire sockets of the main body and turned round and extended out from the wire sockets to form a two-terminal connector, or pressed by the push rod to move a support member downward from a positioning channel at one end of a guide channel of the main body to push against the inner wall of the wire socket to move forward to another end of the positioning channel. The support member is latched by a resilient member, such that the ground terminal is extended out from the ground wire hole and the live and neutral terminals are turned round and extended out from the wire socket to drive the latch member and press on a blocking member to constitute a 3-termainal connector.
