Description
Technical field
The utility model relates to a kind of computer power supply card extender of externally powering.
Background technology
At present relevant with computing machine movably external unit is more, for example mobile CD writer, portable hard drive, part LCD etc., and they all are to adopt dc power source adapter to power.When adopting power supply adaptor to power,, can make desktop seem very in disorder because power supply adaptor is placed on the computer desk; On the other hand, the user need pay the expense of buying power supply adaptor.
Also having a kind of mode, is that a plug is installed on the computer power supply rear wall, from drawing 12V in the power supply to this plug, is outwards powered by this plug.Power supply in this way may need large current charge powering up moment because of the movable part internal capacitance, thereby cause the current foldback circuit action of power supply inside, makes power supply enter guard mode, and external unit also can't operate as normal.
Summary of the invention
The purpose of this utility model provides a kind of computer power supply card extender of externally powering, it utilizes the afterpower of computer power supply to realize safe power supply to external unit, improved the safe reliability of computer power supply and external unit, and make the user not need to buy the power supply adaptor that connects external unit, reduce the quantity of equipment on the desktop.
The technical solution of the utility model is: the designed computer power supply of the utility model externally power card extender by the power input interface that connects this main frame power output end, be used for forming to outside power devices and the power output interface and the filtering circuit that connect external unit, filtering circuit is connected between power input interface and the power output interface.
In the utility model, filtering circuit can comprise inductor and capacitor, and inductor is serially connected with between power input interface and the power output interface, and capacitor connects power output interface and ground respectively.
In the utility model, power output interface can comprise 12V DC voltage output interface and 5V DC voltage output interface, and the size of these two kinds of DC voltage output interfaces is inconsistent, the user can not caused when pegging graft obscure.
In the utility model, can comprise the multiple power supplies output interface.As required, each road power output interface can connect a filtering circuit.The user can power to a plurality of external units according to the afterpower amount of computer power supply.
The computer power supply of the utility model card extender of externally powering can be installed on the cabinet of this main frame.
The utility model is the output terminal of drawing relevant voltage from computer power supply, and the afterpower of utilizing computer power supply is to outside power devices, and increases filtering circuit on the circuit of drawing, and is simple and practical.The utility model not only can provide direct supply to external unit easily, user's external unit of pegging graft is also very simple and convenient, and can be suppressed at the heavy current impact of the powered on moment of external unit by filtering circuit, thereby cause that with the overcurrent protection that prevents too high current trigger computer power supply inside computer operation is undesired, also protect external unit can not damage simultaneously because of rush of current; The all right absorption portion electromagnetism clutter of filtering circuit, thus Conduction Interference reduced, improve the performance of anti-electromagnetic-radiation interference.
Description of drawings
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the block diagram of the embodiment of the utility model;
Fig. 2 is the structural representation of embodiment when using of the utility model;
Fig. 3 is the circuit diagram of the embodiment of the utility model.
Embodiment
Fig. 1 and Fig. 2 illustrate basic structure and the annexation of the embodiment of the utility model.
It goes without doing any change of power supply 200 in the main frame, being connected on the power supply card extender 100 of the utility model is one tunnel big 4PIN accessory power outlet 400.The output of power supply 200 through after the processing of circuit, is exported 12V and 5V from three DC jacks of power supply card extender 100 at power supply card extender 100, and wherein the DC jack size of 12V and 5V is inconsistent, can not cause and obscure.By electric power connection line, the user just can connect portable hard drive, mobile CD-ROM drive or LCD (LCD), and to they power supplies, pegs graft easily.
For from computer power supply 200 to outside power devices, the 5V and the 12V that adopt the power supply card extender 100 of the utility model that power supply 200 is exported draw, as shown in Figure 2.The output interface of computer power supply 200 is still the socket 400 of big 4 PIN, does not need to change.The 5V of power supply on the card extender 100 is respectively the different DC jack of size dimension with the 12V output interface, each other can not interfix, in order to avoid cause the phenomenon that equipment burns out.When needs use external unit, be connected to external unit and just can realize power supply with will power 5V on the card extender 100 or 12V output interface of an electric power connection line to external unit, one end of this electric power connection line should be the DC plug that is complementary on the card extender 100 with power supply, and the other end should be the plug with the external unit coupling.
The filtering circuit circuit of on the power supply card extender 100 of the utility model, forming by inductance and electric capacity; shown in Figure 3 is an embodiment of filtering circuit; this circuit can suppress the rush of current of powered on moment; in case the overcurrent protection of too high current trigger computer power supply inside; thereby cause that computer operation is undesired, also protect external unit can not damage simultaneously because of rush of current.But this circuit is the absorption portion clutter simultaneously, thereby reduces Conduction Interference, improves the EMI performance.
For from computer power supply to outside power devices, computer power supply must have afterpower.As, when adopting the mainboard of INTEL 845 CHIPSET, the power supply of system can be with the 250W P4 power supply that meets the INTEL standard, also available 180W PS3 power supply, the net capability of 12V is the 13A electric current in 250W P4 power specification, the net capability of 5V is the 25A electric current, but the net capability of 12V is the 10A electric current in 180W PS3 power supply, the net capability of 5V is the 12A electric current, relatively can find, if adopt 250W P4 power supply, under the situation of this system, the 12V of this power supply can provide 3A electric current to external equipment, and 5V can provide 13A electric current to external equipment.
As shown in Figure 3, power supply 200 is from 4 PIN sockets, 400 output 12V and 5V voltages, and through the circuit of inductance on the power supply card extender 100 and little electric capacity composition, the DC plug by varying in size is exported to external units such as LCD more then.In this embodiment, the socket J of power supply on the card extender be as power input interface, the socket 400 of can pegging graft; Jack J1, J2, J3, J4 connect external unit as power output interface by electric power connection line.The filtering circuit that is made of inductor L1 and capacitor C1 is connected 1 pin of socket J, and the filtering circuit that is made of inductor L2 and capacitor C2 is connected 4 pin of socket J, exports 12V and 5V to J1 and J2, J3 and J4 respectively.According to the afterpower amount of computer power supply and the power consumption of external unit, a plurality of jacks can be set.Also can dispose a filtering circuit respectively for jack J1, J2, J3 and J4.
If the power of computer power supply is enough big, also its a plurality of power output ends can be connected the power supply card extender of the utility model respectively, to a plurality of external unit power supplies.
