Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1 and 2, this utility model be the technical scheme is that a kind of keyboard switch, including keycap 1, pedestal 8, static contact 7, movable contact spring 6, upper cover 3 and button 2；Keycap 1 covers at outside upper cover 3, and upper cover 3 is fastened on pedestal 8, and static contact 7 and movable contact spring 6 may be contained within pedestal 8；Button 3 can order about the clutch of the movable contact spring 6 on pedestal 8 and static contact 7 by a spring 4 up and downly, button includes a button lid 21, with a key core 22, key core 22 rivets with the medial surface of button lid 21, it is enclosed within button lid 21 in upper cover 3, button be need not again wear upper cover to stretch out, a button inherently closed state, therefore it is greatly improved dust-proof effect.
Concrete, as it is shown on figure 3, hole 200, location can be arranged on key core 22, button lid 21 arranges locating dowel 20, is inserted in hole 200, location by locating dowel 20, then by locating dowel rivet hot, after the change of locating dowel diameter is big, then rivets with hole, location.Also or on key core 22, arrange locating dowel 20, button lid 21 arranges hole 200, location, with the staking process as the former.By hot riveting, enhance the reliability of button.
Preferably, as shown in Figure 4, keycap 1 arranges buckle 11, button lid 21 arranges draw-in groove 211, by buckle 11 and draw-in groove 211 phase clamping, it is achieved the dual dust-proof effect of button and keycap.
Preferably, as it is shown in figure 5, also set up an X support 5 between pedestal 8 and button lid 21 so that when key switch button, surrounding uniform force, button do not tilts, it is smooth and easy to press.Being improved to further, the medial surface surrounding at button lid 21 arranges the screens 212(of X support 5 as shown in Figure 6), it is achieved button 3 is reliably connected with X support 5.
Further embodiment is, X support 5 is divided into X half support 51 and the 2nd X half support 52 coordinated in X, it is respectively provided with a rotating shaft 511 outside the middle part two of the oneth X half support 51, rotating shaft 511 described in both sides is respectively sleeved in the inner side axis hole 521 of described 2nd X half support 52, is coordinated by rotating shaft so that X support can change in location each other, thus realize pressing and the return state of button, easy for installation, and split-type design, structure replacement cost is low.
It is improved to further, as shown in Figure 7, the side that oneth X half support is relative with described 2nd X half support all coordinates with the screens 212 on button lid 21, concrete, X half support with as described in the relative side of the 2nd X half support lead a post 50, in the movable screens 212 being entrapped on button lid 21, it is achieved X half support is freely rotatable in screens 212 respectively with described 2nd X half support and translation gliding.
Being improved to further, on pedestal 8, also card sets a sound shell fragment 9, while button 2 orders about the movable contact spring 6 on pedestal 8 and static contact 7 clutch, separating with sound shell fragment 9, by when compressing switch, button contacts with sound shell fragment, switch can send sound, sends feedback to user.
Concrete, as Figure 8-9, sound shell fragment 9 includes that one with the slide block 91 of buckle 911, buckle 911 snaps in the bayonet socket 81 on pedestal 8.
Another kind of embodiment is, as shown in figs. 10-11, sound shell fragment 9 includes one with the sound shell fragment lid 92 of hole clipping 921, pedestal 8 being provided with and the deck 82 of sound shell fragment lid 92, and deck 82 is provided with stuck point 821, and stuck point 821 coordinates with hole clipping 921.By the sound elastic piece structure 9 of these 2 kinds deformation, it is all to install for the reliability realized with pedestal 8.
Being improved to further, as shown in Figure 12 and Figure 13, sound shell fragment 9 can also include the shell fragment arm 93 of a strip so that what sound shell fragment 9 was subject to is reduced by bonding force, thus improves the service life of sound shell fragment 9.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
