Technology, means and effect of taking for reaching predetermined object in order further to understand the utility model, refer to following relevant detailed description of the present utility model and accompanying drawing.The purpose of this utility model, feature or feature, when obtaining thus one deeply and concrete understanding, but appended graphic only provide with reference to and explanation use, not in order to in addition limitr of the utility model.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model button preferred embodiment.
Fig. 2 is the cutaway view of the utility model button preferred embodiment in the time not being pressed.
Fig. 3 is the cutaway view of the utility model button preferred embodiment in the time being pressed.
Embodiment
As shown in Figure 1-2, the button 1 of the utility model preferred embodiment, can be applicable to various electronic equipments, in order to be arranged on a circuit board 2 of electronic equipment, presses and circuits for triggering, thereby carry out electronic equipment operation for user.
This button 1 comprises main part 11, loading wall 12, extension 13, conductive base 14 and multiple support column 15.Wherein, main part 11 use are pressed for user; Loading wall 12 is tilted to outer and is extended to form downwards by main part 11 bottom outer rims, and the extension side of this loading wall 12 is connected to extension 13, that is to say, main part 11 is connected by loading wall 12 with extension 13; This extension 13 is for being arranged at the circuit board 2 of electronic equipment; Conductive base 14 is arranged at the bottom of main part 11, and it is column, convexedly stretches in 110 centers, bottom surface of main part 11, corresponding to conducting strip set on circuit board 2 21.
Multiple support columns 15 are arranged at the bottom of main part 11, convexedly stretch on main part 11 bottom surfaces 110.The plurality of support column 15 can be arranged at conductive base 14 around, or arranges along main part 11 bottom outer rims, contiguous loading wall 12.Preferably, the plurality of support column 15 is arranged at symmetrically or equably the surrounding of conductive base 14 or arranges along main part 11 bottom outer rims, close loading wall 12, for example when main part length is large, width hour, can be symmetrical arranged two support columns near loading wall in main part both sides along its length, but be not limited to this.Certainly, the plurality of support portion 15 also can asymmetric or inhomogeneous setting.Preferably, the height of the plurality of support column 15 is slightly less than the height of conductive base 14, to guarantee the fully conducting strip 21 on contact circuit plate 2 of conductive base 14; And in the time that main part 11 pressurizeds tilt, be positioned at main part 11 pressurized one sides support column can with circuit board butt, main part 11 is produced and supports, and now, the also abundant conducting strip 21 on contact circuit plate 2 of conductive base 14.
As shown in Figures 2 and 3, in the time that this button 1 is arranged on circuit board 2, the extension 13 of button 1 is fixed on circuit board 2, so that this button 1 is located.This extension 13 can be directly fixed on circuit board 2 by modes such as boning, be spirally connected, also can be limited on circuit board 2 by circuit board 2 and the respective outer side edges of the housing (not shown) of electronic equipment.Now, conductive base 14 is corresponding to the conducting strip 21 on circuit board 2.
Press main part 11, conductive base 14 together moves down with main part 11 with multiple support columns 15, even if not pressing main part 11 in the centre of main part 11, user make main part 11 along tilted by force direction, as power F direction in Fig. 3, once support column 15 and circuit board 2 butts, main part 11 is produced and supported, make main part 11 be adjusted to normal level state, can guarantee that thus the conducting strip 21 of conductive base 14 complete contact circuit plates 2 is with the circuit on circuits for triggering plate 2, as shown in Figure 3, thus electronic equipment is operated.When main part 11 is discharged by user, this main part 11 can be under the elastic force effect of loading wall 12, returns to normally not pressed state (shown in Fig. 2).
Visible, the utility model button 1 is by arranging support column 15 in main part 11 bottoms, main part 11 is provided support in the process being pressed at main part 11, can make this button 1 automatically adjust the heeling condition of main part 11 in the process of being pressed, guarantee fully contacting of conductive base 14 and circuit board 2 conducting strips 21, avoid its loose contact.Meanwhile, because support column 15 can provide support and automatically adjust to main part 11 heeling condition of main part 11, therefore can avoid this button 1 to be installed in electronic equipment time, produce collision friction and cause card key with the shell of electronic equipment.
The utility model button is applicable to that the key device of various electronic equipments, particularly main part have more greatly or the key device of longer size.In addition, this button forms the situation of key-press module applicable to multiple buttons are connected, between adjacent key, be connected by its extension.
The foregoing is only preferred embodiment of the present utility model, not in order to limit claim scope of the present utility model, therefore all other do not depart from the equivalence completing under the spirit that the utility model discloses and changes or modify, and all should be contained in scope of the present utility model.
