Abstract
The utility model relates to an integratedly arranged I/O interface board, wherein, an input terminal of the interface board is provided with a switching insertion opening circuit which is connected with a wiring interface of a relative peripheral device on a main board. The output terminal of the circuit is connected with a keyboard, a mouse, a USB interface and an outer connection display interface. A high frequency filter circuit is arranged among the USB interface, the outer connection display interface and the switching insertion opening circuit. The high frequency filter circuit is composed of inductance and capacitance. The utility model switches the connection of each peripheral device of a computer and a host computer, and each peripheral device is arranged singly. The interface of each peripheral device of is concentrated so that the size of the main board is reduced. The flexible wiring and the wire output of the mother board are convenient, the utility model brings bigger space for the integrated design of a system so that use operation is simple.
Description
The utility model relates to a kind of mainboard interface parts of each peripherals of computing machine, especially a kind of I/O interface board that can dwindle the concentrated setting of mainboard size, handled easily significantly.
Along with the microminiaturized requirement of using development trend of computing machine, the size of mainboard size is limiting the integrally-built change of computing machine always at present.Existing computer mainframe structure is that each peripherals must directly be connected with the interface position of mainboard.Because each peripherals is different with the link position of mainboard, occupies than large space respectively.Also just because of the taking of space, the wiring of mainboard is subjected to bigger restriction.Have again in traditional Computer System Design, because the mainboard size is bigger, and will look after the fixed relationship of CPU and heat radiator thereof, and the position of PCI plug-in card relation, the position of mainboard can not arbitrarily be moved.Each peripherals must directly be connected with mainboard, and line outlet can only be fixed with the structure of mainboard, is unfavorable for the system design of computing machine integral body.In addition, the present interfaces scattered distribution brings inconvenience to the user, and increasing people require the simple to operate easy-to-use of each peripherals line of computing machine.Therefore be necessary very much to design to concentrate the I/O interface board that is provided with, so that overcome many deficiencies of prior art.
Fundamental purpose of the present utility model is to provide a kind of I/O interface board of concentrated setting, each peripherals of computing machine and being connected of main frame are transferred, the independent setting, and concentrate each peripheral interface, so that dwindle the mainboard size, make things convenient for the flexible wiring and the outlet of mainboard, bring bigger space, also use operation more simple to overall system design.
Another purpose of the present utility model is to provide a kind of I/O interface board of concentrated setting, increases on this interface board to be provided with external display interface device.
The purpose of this utility model is achieved in that
A kind of I/O interface board of concentrated setting, the input end of wherein said interface board be provided with mainboard on the socket circuit of corresponding peripheral device line interface switching, the output terminal of this circuit is connected to keyboard, mouse, USB interface.
Be provided with high-frequency filter circuit between described USB interface and the switching socket circuit.
Described switching socket circuit is connected to external display interface device.
Be provided with high-frequency filter circuit between described external display interface device and the switching socket circuit.
Described high-frequency filter circuit can be the high-frequency filter circuit of inductance, electric capacity composition.
Because the utility model can be transferred each peripherals of computing machine and being connected of main frame, therefore each peripherals directly is not connected with mainboard, mainboard is provided with the position of connection needn't for each peripherals, as long as keep and line interface of the present utility model, thereby dwindled the size of mainboard greatly, make mainboard that more integrated circuit can be set, also made things convenient for the wiring of mainboard simultaneously.Have again, mainboard to go out line position flexible, no longer be restricted, be convenient to whole structural design.Because it has concentrated each peripheral interface independently, user's line operation is very simple.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
The structured flowchart of Fig. 1 for concerning between the utility model formation and mainboard, each peripherals.
Fig. 2 is the utility model circuit theory diagrams.
Referring to Fig. 1,2, the utility model is a kind of I/O interface board of concentrated setting.The input end of interface board be provided with mainboard on the switching socket circuit PS2/COM/LPT of corresponding peripheral device line interface, the output of this circuit is connected to keyboard KEY, mouse MOUSE, USB interface, and external display interface device VGA.For guaranteeing the quality of signal output/input, improve antijamming capability, and guarantee the electromagnetic radiation shielding of mainboard, be provided with high-frequency filter circuit between USB interface and the switching socket circuit and between external display interface device VGA and the switching socket circuit, this high-frequency filter circuit can be a plurality of resistance R, inductance L, capacitor C composition.High-frequency filter circuit between USB interface and the switching socket circuit is by inductance L 1-L9, and capacitor C 1, C7 form; High-frequency filter circuit between external display interface device VGA and the switching socket circuit is by inductance L 11-L12, and capacitor C 8, C10 and resistance R 1-R3 form.
The peripheral hardware that adopts the utility model originally must be connected with mainboard changes into the I/O interface board of concentrating and being connected.Because the utility model circuit is simple, do not have that volume is big, the heavier integrated circuit of weight, so can optionally be arranged in the Computer Systems Organization.
