Embodiment

Following with reference to accompanying drawing, be that example is further described the utility model keyboard with the computor-keyboard.

Please refer to Fig. 1-shown in Figure 4, the utility model keyboard 100 comprises loam cake 1, lower cover 2, keypad (rubber) 3, conductive foil (membrance) 4, pcb board 5 and iron plate (not shown), and described keypad 3, conductive foil 4, pcb board 5 and iron plate are according to being set in sequence between loam cake 1 and the lower cover 2 from the top down.

Please be simultaneously with reference to Fig. 6-Fig. 8, loam cake 1 comprises loam cake body 10, is arranged on the some keycaps 11 on the loam cake body 10, the interspersed plastic cement post 15 of the some reference columns (not label) on the loam cake 1, the leaded light post 12 that is arranged on loam cake 1 neighboring edge place, contiguous loam cake 1 relative both sides of the edge and the grab 13 and fixture block 14 at contiguous loam cake 1 other edge, two opposite sides of being arranged on.Described keycap 11 can be wholely set with loam cake 1, also can be to be embedded separably in loam cake 1.Described grab 13 comprises the grab main body 131 of extending perpendicular to loam cake 1 back side and with reference column and plastic cement post 15 almost parallels and from the crook 132 of grab main body 131 projectioies.

Please be simultaneously with reference to Fig. 2-Fig. 5, Fig. 9, keypad 3 is a sheet, comprises key panel 30 and is wholely set button 31 on key panel 30.Described keypad 3, conductive foil 4 and iron plate are provided with the some pilot holes corresponding with the loam cake reference column (not label) respectively.

Described lower cover 2 comprises lower cover main body 20, is enclosed the receiving space 21 that forms, is arranged on support slot 23 and the draw-in groove 24 on lower cover main body 20 two opposite side walls and is arranged on fin 22 in the receiving space 21 by the wall of lower cover main body 20.Described support slot 23 is arranged on receiving space 21 inside, and described draw-in groove 24 is arranged on the outside of receiving space 21, and lower cover 2 is provided with and also is provided with the trough 25 that passes for cable on the wall of draw-in groove 24.The lower surface of described lower cover 2 is provided with some pilot holes (not label) and accepting groove 28, offer pilot hole (not shown) on accepting groove 28 diapires for tightening member 27 fastening upper and

lower covers

1,2, described lower cover 2 also is provided with the feet 26 that can stack or open, and described feet 26 can cover accepting groove 28 when folding.

During assembling, iron plate is positioned on the fin 22 in lower cover 2 receiving spaces 21, pcb board 5, conductive foil 4 and keypad 3 are by successively being successively set in the receiving space 21 and entirely being positioned on the iron plate, the mode of aiming at the pilot hole of keypad 3, conductive foil 4, iron plate and lower cover 2 with the keycap 11 of loam cake 1 facing to the button 31 on the keypad 3, reference column is inserted the grab 13 of loam cake 1 in the support slot 23 of lower covers 2, fixture block 14 inserts in the draw-in grooves 24, realizes the fastening of upper and lower cover 1,2.For prevent that grab 13, fixture block 14 from easily coming off from support slot 23, draw-in groove 24, insert in the plastic cement post 15 that is arranged on the loam cake 1 from lower cover 2 basal surfaces with tightening member 27.

When keyboard 100 needs to clean, with tightening member 27 take off, grab 13, fixture block 14 break away from support slot 23, draw-in groove 24 respectively, take off loam cake 1 from lower cover 2 again, because keypad 3 designs for one, therefore button 31 can be not at random because of removing of keycap 11, and because electronic component, all be placed on as pcb board 5, conductive foil 4 in the receiving space 21 of lower cover 2, loam cake 1 can immerse fully to be scrubbed in the water till the cleaning fully.
