Embodiment

Refer to Fig. 1 and Fig. 2.Keyboard 200 comprises keyboard body 210, connecting line 150 and shielding case 121.These shielding case 121 telescopicallies are contained in this keyboard body 210, and this shielding case 121 has shielding space 120, for shielding electromagnetic wave.

This connecting line 150 comprises the first link 151 and the second link 152 that are oppositely arranged.This first link 151 is for being connected with external device (as host computer 100).This second link 152 is connected with keyboard body 210.This second link 152 comprises first interface 1097 and at least one the second interface 1095.This first interface 1097 is for transmitting the operational order of keyboard.This at least one second interface 1095 is arranged in shielding case 121, and for transmission of data signals, these shielding case 121 activities are housed in this keyboard body 210 and can stretch out this keyboard body 210 by keyboard body 210 1 sides.

This connecting line 150 can arrange hub and receive the keyboard operation instruction of first interface 1097 and data-signal to the first link 151 of the second interface 1095, particularly, this hub can be the hub (Universal Serial Bus hub, USB HUB) of USB (universal serial bus).This connecting line 150 also can receive the keyboard operation instruction of first interface 1097 and the data-signal of the second interface 1095 same up to the first link 151 simultaneously.In the present embodiment, employing is that the second receives and transmission mode.Particularly, this first link 151 comprises at least two the first connectivity ports 1093.In each first corresponding first interface in connectivity port 1,093 1097 and at least one the second interface 1095 one, for transmitting a kind of electric signal.Wherein the first connectivity port 1093 is opposite ends of a data line 109 with first interface 1097 or at least one the second interface 1095 one to one.In other words, this connecting line 150 comprises at least two data lines 109.These at least two the first connectivity ports 1093 are connected with an external device (as host computer 100), in these at least two the first connectivity ports 1093, have keyboard connectivity port and general series bus connection port, this two port is connected with USB (universal serial bus) 108 with the keyboard interface 108 being electrically connected with its circuit board 106 on host computer 100 respectively.At least one the second interface 1095 that the USB (universal serial bus) 108 with on host computer 100 circuit boards 106 of this connecting line 150 is connected is arranged in this electromagnetic wave shielding space 120, the electromagnetic wave producing when shielding work further; The first interface 1097 being connected with the keyboard interface 108 on host computer 100 circuit boards 106 is electrically connected with the keyboard pcb 1098 of the interior reception keyboard operation of keyboard 200 instruction, for transmitting the entering the operating instructions to host computer 100 of keyboard 200.Understandably, this at least one second interface 1095 can adopt hub to utilize same data lines 109 to carry out data transmission, also can utilize respectively a data lines 109 to carry out data transmission by each second interface 1095.

Preferably, this shielding case 121 is metal shell formation.

Particularly, the inside of this keyboard body 210 has a receiving space 211, and this receiving space 211 is for accommodating this shielding case 121.This shielding case 121 comprises Part I 122 and is flexibly connected the Part II 123 of this Part I 122.In the present embodiment, Part I 122 is arranged on the inwall of this receiving space 211 of formation of this keyboard body 210 and in the face of this Part II 123.This Part II 123 is inside and outside two side shiftings of this keyboard body 210 relatively, in the time that Part II 123 moves to keyboard body 210 outside, this shielding case 121 is opening, at least one the second interface 1095 being connected with the USB (universal serial bus) 108 of circuit board 106 is exposed, be convenient to Portable movable memory device, as the grafting of USB flash disk.In the time that Part II 123 moves to the receiving space 211 of keyboard body 210 inner sides, this shielding case 121 closes, this Part I 122 covers this Part II 123 completely, and this Part II 123 forms the shielding space 120 sealing to shield preferably the electromagenetic wave radiation producing in the time that at least one the second interface 1095 is worked with Part I 122.

Above-mentioned keyboard 200 has the second interface 1095 of transmission data, makes keyboard the function in entering the operating instructions with transmission of data signals is provided, easy to use.Further, because the second interface 1095 is contained in the shielding case 121 of keyboard 200, this shielding case 121 can reduce the impact to external world of electromagnetic wave that the second interface 1095 produces in when work.

Understandably, in present embodiment, because shielding case 121 is arranged in keyboard body 210, therefore its space size is limited, the second interface 1095 being contained in shielding case 121 can be the interface end that USB (universal serial bus) end, SD card (safe digital card) interface end etc. are connected with small-sized memory device, is convenient to memory device small-sized after this Part II 123 coordinates with Part I 122 and can be contained in shielding space 120.

In the present embodiment, this Part I 122 is tabular, and this Part II 123 comprises rectangular base plate 125 and end to end four sidewalls 126 that the edge of this base plate 125 extends to homonymy certainly, and this at least one second interface 1095 is arranged on this base plate 125.The shielding space 120 that this base plate 125 and this four sidewall 126 and Part I 122 form is to shield this second interface 1095.Wherein on two sidewalls 126 that are oppositely arranged in the outside in the face of this keyboard body 210 in Part II 123, there is respectively projection 128, one side of the projection 128 in the face of this Part II 123 of this keyboard body 210 has chute 222, and the slip of projection 128 in this chute 222 realizes Part II 123 in inside and outside the stretching of this keyboard body 210.The xsect of this projection 128 is T-shaped, and the xsect of this chute 222 is T-shaped.

In addition, the special construction of keyboard 200, can reduce the open amount of host computer 100 casings while making it be applied to host computer 100, further can reduce the amount to extraneous radiated electromagnetic wave of host computer 100.Particularly, this host computer 100 has the first housing 102.This first housing 102 is accommodated circuit board 106 and interface 108 thereof.The first link 151 of this connecting line 150 stretches into this first housing 102 inside, and these at least two the first connectivity ports 1093 are connected with the interface 108 on circuit board 106 in these the first housing 102 inside.
