One built-up circuit, itself and the above-mentioned inner port of respectively importing electrically connect;
Several output interfaces, it comprises an output external port and an output inner port respectively, each is exported inner port and electrically connects with above-mentioned built-up circuit respectively;
Some patchcords, it comprises a switching input and a switching output respectively, and each input of transferring electrically connects with an above-mentioned output external port respectively, and each output model of transferring is different.
Especially, above-mentioned input external port is the different input external port of several models, so can make things convenient for the patching of power interface of all kinds power supply adaptor or power supply unit.
Especially, above-mentioned input interface is one, and the output external port model of the input external port of this input interface and several output interfaces is identical, makes that so the input/output port of power-supply adapter is unified.
Especially, above-mentioned built-up circuit comprises a switch, in order to the output of control power supply.
Whether normally especially, above-mentioned built-up circuit comprises a display lamp, in order to show the output of this power supply.
Especially, above-mentioned built-up circuit comprises several diode groups, each diode group comprises the diode of the unidirectional conducting of two parallel connections respectively, and each diode group is connected with an output inner port respectively, the anti-filling of power supply that causes in order to prevent above-mentioned input external port and output external port from mispluging.
Compared with prior art, utilize power-supply adapter of the present invention, because the switching output model of each patchcord is different, by offering the laptop electric power input port of various models after the patchcord, compatibility is very strong, can make control to power supply rapidly and easily, saves time conveniently.
[description of drawings]
Fig. 1 illustrates the structural representation into power-supply adapter one preferred embodiment of the present invention.
[embodiment]
See also Fig. 1, Fig. 1 illustrates the structural representation into power-supply adapter one preferred embodiment of the present invention.
For reaching above-mentioned purpose, power-supply adapter provided by the invention is done switching in order to the power interface that power supply adaptor or power supply unit are provided, and uses for different laptop electric powers input port, and in present embodiment, this power-supply adapter 1 comprises:
An input interface 10, it comprises an input inner port 101 and an input external port 100, wherein this input external port 100 electrically is plugged with power supply adaptor 2 power interfaces 20;
One built-up circuit 11, itself and above-mentioned input inner port 100 electrically connect, this built-up circuit 11 comprises a switch 110, output, this built-up circuit 11 in order to the control power supply comprise a display lamp 111, in order to show this power supply whether normally output, this built-up circuit 11 comprise several diode groups 112, each diode group 112 comprises the diode of the unidirectional conducting of two parallel connections respectively;
Two output interfaces 12, it comprises an output external port 121 and an output inner port 120 respectively, each is exported inner port 120 and electrically connects with above-mentioned built-up circuit 11 respectively, each is exported inner port 120 and electrically connects with a diode group 112 respectively, the anti-filling of power supply that causes in order to prevent above-mentioned input external port 100 and output external port 121 from mispluging;
