Embodiment
Referring to shown in Figure 4, a preferred embodiment of the utility model keyboard comprises a housing 40 and a plurality of being located on the housing 40, and the confession user pushes the button 4 to import.
Referring to Fig. 5 and shown in Figure 6, be respectively the side-looking exploded view and the constitutional diagram of the one key 4 among Fig. 4.As shown in the figure, button 4 comprises a metal fixed head 41, one is located at the metal keyboard 42 of metal fixed head 41 upper surfaces, one base plate 43, one is located at the circuit board 44 on the base plate 43, one is located at the insulation film 45 on the circuit board 44, one is located between insulation film 45 and the metal fixed head 41, with the elastic component 46 that an elastic-restoring force is provided, an and lifting support unit 47 of being located between metal fixed head 41 and the base plate 43, when metal keyboard 42 stressed pressing down, metal fixed head 41 can be with lifting support unit 47 towards base plate 43 direction vertical moving.
The metal keyboard 42 of present embodiment also can be one-body molded with metal fixed head 41 except seeing through scolding tin welding or viscose stick on the metal fixed head 41, as shown in Figure 7.And the material of metal keyboard 42 and metal fixed head 41 can adopt aluminium alloy or almag.
The lower surface of metal fixed head 41 is by punching press and be bent to form a pair of first chute 411 and a pair of first draw-in groove 412, and the upper surface of base plate 43 is provided with a pair of second chute 431 and a pair of second draw-in groove 432.Circuit board 44 is film circuit boards, and a switch (figure does not show) is set on it, for example thin film switch (membrane switch) or other triggering property switch.Insulation film 45 can be a wheat membrane (mylar film) or other can be used as the plastic material of insulation applications.
