Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated, in order to facilitate drawing performance and explanatory note, the accompanying drawing except Fig. 1 represents with single button, and certain cantilever type keyboard can comprise several buttons.
Consult Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the utility model cantilever type key board unit comprises a metal base plate 1, a circuit board 2, an actuating unit 3, an interval box 4, and a push-button unit 5.This circuit board 2 is arranged at this base plate 1 top and comprises several switches 21.
This actuating unit 3 comprises that one is layed in this circuit board 1 top and for being electrically insulated slide glass 31, several metallic elastic domes 32 that are convexly set in respectively this slide glass 31 and are positioned at described switch 21 tops of body, and several are arranged at respectively the elastic cushion 33 of described elasticity dome 32 tops.
Described elasticity dome 32 is compressive deformation and activate corresponding switch 21 respectively.Described elastic cushion 33 is used for the buffering user and points the reaction force that is subject to when typewriting is stroked, and can improve comfort.
This interval box 4 is the body that is electrically insulated, and utilizes two-sided viscose 6 gluings to be arranged at this slide glass 31 tops.
This push-button unit 5 comprises a connection box 51, several are spaced the perforation 52 in this connection box 51, and several be arranged at respectively described perforation 52 and wherein a lateral margin be connected in the key body 53 of this connection box 51.
This connection box 51 is layed in this actuating unit 3 and these interval box 4 tops and shape corresponding to the shape of this interval box 4, and utilizes two-sided viscose 6 gluings in these interval box 4 end faces, thereby this interval box 4 is located in 51 of this slide glass 31 and this connection boxes.The position of described perforation 52 is corresponding to the position of elasticity dome 32, and the size of described perforation 52 is greater than the size of elasticity dome 32.Key body 53 is positioned at the top of corresponding elastic cushion 33.
