Specific embodiment
The application is described in further detail below by specific embodiment combination attached drawing.
Shown in Figure 1, button cap provided in this embodiment includes: nut cap 10 and ennation 20, and ennation 20 is arranged
In the bottom surface of nut cap 10, the top surface of nut cap 10 is the arc surface of convex or concave, which is press surface, and as finger presses
Face, be set to arc surface to adapt to the pressing of finger.In the present embodiment, the top surface of nut cap 10 is specially the circular arc of evagination
Face.As shown in fig. 1, the bottom surface of nut cap 10 is the lower surface of nut cap 10, and the top surface of nut cap 10 is the upper surface of nut cap 10.
Ennation 20 includes: main body 21, at least one guiding rib 22, and the recessed portion to 20 sunken inside of ennation
23.At least one guiding rib 22 along the outer wall that main body 10 is arranged in the length direction of main body 21, prolonging by the setting of recessed portion 23
The bottom of body 20 is stretched, the bottom of the ennation 20 is the lower end surface of ennation 20.The recessed portion 23 with key 30 for contacting
The pressing force for being applied to the top surface of nut cap 10 is passed to key 30, to touch actuation of keys, key is made to be switched on or switched off electricity
Road.
In the present embodiment, guiding rib 22 is provided with multiple, and the equal subarrays of multiple guiding ribs 22 are fixed on main body 21
Outer wall on, and multiple guiding ribs 22 extend the bottom of main body 21 after form recessed portion 23.Shown in referring to fig. 2, main body
21 be cross-type shape, and there are four the settings of guiding rib 22, and four guiding ribs 22 are separately positioned on the four of cross main body 21
On a side, four guiding ribs 22 and main body 21 form cross shape.Recessed portion 23 be arranged in the cross shape bottom,
And to cross-type shape sunken inside.The length of four guiding ribs 22 is greater than the length of main body 21, in the bottom surface of main body 21
End forms four protruding portions, the bottom end formation recessed portion 23 of four protruding portions and main body 21.
Shown in Figure 3, the side wall of recessed portion 23 has the inclined gradient of outer wall to ennation 20, and Formation cross-section is ladder
The recessed portion 23 of shape shape.As described above, the side wall of recessed portion 23 is to be formed after four guiding ribs protrude from main body 21
Four protruding portions inside.The circumferential extent of the top side wall of recessed portion 23 is less than the circumferential extent of sidewall bottom, and is recessed
The circumferential extent of the top side wall in portion 23 is suitable for the circumferential extent of key 30.I.e. the circumferential extent at the top of recessed portion 23 and its
The circumferential extent of bottom is all larger than the circumferential extent of key 30, has certain interval between key 30 and the side wall of recessed portion 23,
In this way at the top surface of pressing keys cap 10, key 30 will not be stuck in recessed portion 23.When ennation 20 moves down, main body
