  • Patent number: 8004811
    Abstract: The present invention provides a power strip having a surge protective circuit. When a surge is inputted into the power strip, the surge is subject to two-stage suppressions so as to protect the electrical appliances which are electrically connected to the power strip. The surge protective circuit of the power strip includes a first surge protective device, a buffer conductive device and a second surge protective device. The buffer conductive device is relatively small-sized and cost-effective in comparison with the bulky inductor used in conventional power strip.

  • Patent number: 6907122
    Abstract: A rotational split adaptor for engaging with gold-plated contacts of a communication socket is introduced to comprise a common plug, a socket assembly and a rotational joint. The common plug further includes a plug end for engaging with the communication socket and an opposing first oblique surface. The socket assembly further includes a splitter and an opposing second oblique surface. The splitter has a plurality of parallel sockets electrically coupling with the communication socket, and the second oblique surface is used to pair with the first oblique surface. The rotational joint is constructed to pair the first oblique surface and the second oblique surface so as to provide angular sliding in between and thus to alter angling between the socket assemble and the common plug.

  • Patent number: 6805565
    Abstract: A box adaptor with a revolvable socket dome is introduced to have a housing and at least a dome structure. The housing further include a bracket plate. The dome structure further includes a collar shaft at one end for forming a revolvable pair with the bracket plate and a dome surface at another end. At least a socket is constructed to a rim of the dome surface, with a facing direction perpendicular to the dome surface. By providing the engagement of the collar shaft and the bracket plate, the socket can change its facing direction as the respective dome structure revolves about the bracket plate.

  • Publication number: 20030085108
    Abstract: An electrical safety outlet includes a safety switch for a standard three-prong electrical outlet. The switch is located directly between the neutral and voltage slots on the outlet. In its normal state, the switch is not depressed, shutting off all current to the electrical outlet. However, when an electrical plug is inserted into the outlet, the main body of the plug will depress the switch, allowing the flow of current to begin. The addition of the safety switch will considerably reduce the risk of accidental electrical shock, which is especially effective towards children.

  • Publication number: 20030077930
    Abstract: A power plug has a housing, a voltage prong, a neutral prong, and a ground prong, the prongs set in the housing, and a main body elastically set in the housing and encircling the prongs. When plugging the power plug into a socket, the main body retracts toward the housing. When unplugging the power plug from the socket, the main body is pushed outward to cover the prongs. In such a manner, only a small section of each prong is exposed to open air or the prongs are not exposed at all, increasing the safety of the power plug.

  • Patent number: 6528970
    Abstract: A charger includes a direct current (DC) converter and an alternating current (AC) converter. The DC converter includes a DC input port, a conversion circuit, a transmission port for inputting a second voltage, an output port, and a switch for selectively outputting the first voltage or the second voltage. The AC converter has an AC input port, an AC conversion circuit for transforming an AC power source to the second voltage, and a power port corresponding to the transmission port for outputting the second voltage to the transmission port. The DC converter and the AC converter are capable of engaging with each other such that the power port is connected to the transmission port, and the charger can provide power via the output port provided by the AC power source or the DC power source.

  • Patent number: 6135820
    Abstract: A conductive electrode structure for a double-sided multi-socket adapter panel comprising a live conductive electrode bar and a neutral conductive electrode bar that provides the optimal number of plugging sockets as well as distance of separation for neighboring plugging sockets. Furthermore, the plugging sockets in each side of the adapter panel are oriented in such a way that all the live and neutral plugging slots are aligned in a row, thereby eliminating undesirable interference from neighboring plugging cables. In addition, some of the plugging sockets are spaced so far apart that even a large plug from a transformer adapter can be plugged without affecting plugging sockets in its neighborhood.

  • Patent number: 6121868
    Abstract: The present invention provides an electric device comprising two electric terminals, a button mechanism having a push button that can depressed to toggle between "on" and "off" statuses, and a conductive reed that conducts electric current between the two electric terminals when connected and disables the passage of current when disconnected. When the button is set "on", a reserve space exists between the reed and the button for the reed to spring upward without pushing the button upward. When the current passing through the reed exceeds a predetermined current level, the reed will become heated and spring upward and rest in the reserve space so as to electrically disconnect the two electric terminals.

  • Patent number: 5971808
    Abstract: A double-sided multi-socket adapter panel whose plugging sockets alternate between two opposite sides of the adapter panel such that some of the sockets are separated further apart so that even large-size plug of a transformer adapter can be accommodated without affecting the availability of neighboring plugging sockets. The electrode-plugging slots are aligned along a straight line parallel to the general layout direction of the plugging sockets, and therefore suitable for plugging vertical plugging head. Furthermore, each plugging socket has a protective cover capable of sliding so that whenever a plugging socket is unused, the plugging slots of the socket can be shut to prevent dust from entering or any accidental touching by somebody. The conductive electrode structures are designed such that the optimal number of plugging sockets and distance of separation between two sockets are obtained.
