Abstract:
A transmission line that is plugged and unplugged includes a wire and at least one socket connecting to one end of the wire. The socket is connected to an electronic device and coupled with a force applying member. The force applying member rams the electronic device when subject to a force to facilitate separation of the socket and the electronic device. The force applying member is hinged on the socket and is divided by the hinged location to form a force applying portion and a pressing portion. When the force applying portion receives the force, the pressing portion generates a counter force about the hinged location against the electronic device to make the socket to be removed from the electronic device.
Abstract:
An external power distribution architecture of a power supply, wherein the existing DC voltages V1, V2 transformed from AC by the power supply are further transformed into the power used by external electronic devices plugged in external power ports. In the present invention, two different levels of DC voltages V1, V2 transformed by the power supply are defined to be voltage sources, and two different levels of target DC voltages V3, V4 output by the external power ports are respectively derived from the DC voltage sources V1, V2 closest to corresponding target voltages V3, V4. Thereby, the present invention can balance power output and reduce transformation power loss.
Abstract:
A power supply equipped with an independent overload protection mechanism includes a transformation circuit which consists of a plurality of transformers for transforming AC power to DC power. Each transformer has a front end connecting to a power switch. All the power switches are connected to a pulse-width modulation (PWM) controller. Each power switch and the PWM controller are bridged by a switch circuit which is electrically connected to a protection circuit to monitor whether an electronic device is overloaded. In the overload condition, the protection circuit outputs a protection signal to the switch circuit to stop or suspend the DC power cord from delivering electric power to drive the electronic device at the rear end. Hence an independent overload protection can be achieved.
Abstract:
A power supply equipped with an independent overload protection mechanism includes a control circuit and a transformation circuit that form multiple sets of combination circuits for transforming AC power to DC power. Each control circuit is connected to a protection circuit which monitors overload operation conditions of an electronic device. In the event that an overload condition occurs, the protection circuit outputs an individual protection signal to the control circuit to stop or suspend power output on a DC power cord so that the electronic device at the rear end is not driven. Hence an independent overload protection can be achieved.

A power supply load selection control circuit is adopted for use on a power supply which has a maximum power utilization limit. The power supply has a power protection circuit which includes a power reference circuit to provide a limited power value. The limited power value is determined via reference elements located on the power reference circuit to generate different reference power values and a switch electrically connected to the reference element circuits. Users can determine the limited power value according to load requirements to select the optimum power of the power supply and achieve protection purpose.

The present invention discloses a current-limiting protection circuit for a power supply, which applies to a power supply that has a maximum power-limiting function, wherein the user will be alarmed by a time-delay alarm circuit of the current-limiting protection circuit when the power used by the loads is in a heavy-load state or a full-load state, and within the delay time preset in the time-delay alarm circuit, the user can adjust the power-limiting value according to the power needed by the loads. Thus, via the current-limiting protection circuit for the power supply of the present invention, the objective of the best power selection and protection of the power supply is achieved.

A bus interface is installed on the computer host and the bus interface has a power transmission terminal and a data transmission terminal. The data transmission terminal is electrically connected with the data transmission port of the motherboard, and the power transmission terminal is electrically connected to the standby power system such that the bus interface can receive the DC power from the standby power system when the computer host is under operation or shutdown.
Abstract:
The present invention discloses an overload protection control mechanism for a power supply, wherein a control mechanism installed between two connectors automatically switches the DC power states of the output signal of the overload protection circuit according to the electric connection state between two connectors. Thereby, the present invention not only can prevent the user, who lacks the knowledge of the overload protection circuit, from incorrectly operating the overload protection circuit but also can protect electronic devices from the damage induced by that an unintended touch switches the overload protection circuit erroneously.
