Abstract

The utility model relates to a button structure and is used for cooperating with the touch switch of a PCB, aiming at solving the problem that the button and the PCB touch switch can not fully contact with each other when two ends of the button structure are pressed down. The button structure is provided with a contact at the bottom, with the contact comprising a long edge and a short edge and the contact being corresponding to the touch switch. The button contact can fully contact with the PCB touch switch when any part of the button structure is pressed down, thereby realizing full conduction. Moreover, the button can bounce out no matter how hard the button is pressed down.

Description

Press-key structure

Technical field

The utility model relates to a kind of press-key structure.

Background technology

Fig. 1 illustrates the press-key structure on the pcb board, and as shown in Figure 1, the control switch on the pcb board 10 uses circular touch-switch 11 (with reference to Fig. 3) usually, and configuration button 12 on it.At present, columniform design is adopted in the contact 13 of button 12, as shown in Figure 2.When the user pressed at button 12 two ends, the serious deflection in contact caused contact 13 can't fully contact with touch-switch 11 on the pcb board and can't conducting.If excessive press button 12 to be sagged can't eject come, influence the button effect.

The utility model content

The problem that button and pcb board touch-switch can't fully contact when pressing at the button two ends in order to solve, the utility model provides a kind of button that improves contact structure that has.

The utility model is that to solve the problems of the technologies described above the technical scheme that adopts be to propose a kind of press-key structure, is used for cooperating with the touch-switch of pcb board.The bottom surface of this press-key structure has a contact, and this contact has a long limit and a minor face, and this contact is relative with this touch-switch.

In above-mentioned press-key structure, the cross sectional shape of this contact is an O shape.

In above-mentioned press-key structure, this touch-switch is circular.

The utility model is owing to adopt above technical scheme, make it compared with prior art, the contact design of elongated cylindrical, no matter when where button is pressed, can both reach the contact fully contact with the pcb board touch-switch and make the abundant conducting of pcb board, can not produce situation about not going out because of the excessive bullet that pushes button.

Description of drawings

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, wherein:

Fig. 1 illustrates existing button and contacts schematic diagram with circular touch-switch on the pcb board.

Fig. 2 illustrates existing keyboard structure.

Fig. 3 illustrates the circular touch-switch on the existing P CB plate.

Fig. 4 illustrates the press-key structure of one embodiment of the invention.

Fig. 5 illustrates button of the present utility model and contacts schematic diagram with circular touch-switch on the pcb board.

Embodiment

Fig. 4 illustrates the press-key structure of the utility model one embodiment.With reference to shown in Figure 4, the bottom surface of the press-key structure 22 of present embodiment has contact 23, and this contact 23 is equivalent to a cylinder from radially being elongated.That is to say that the cross section of contact 23 is " O " shape, two end is semicircle, and the middle part is a rectangle.Like this, this cross section has long limit and minor face.If press-key structure 22 is rectangle or other shapes with long limit and minor face, easy of big deflection at two ends, long limit usually, the long limit bearing of trend of contact 23 is consistent with the long limit bearing of trend of press-key structure 22 usually so.Be appreciated that the utility model is not limited to this contact, but can use the contact of other shapes, for example ellipse, rectangle etc. with long limit and minor face.

When this press-key structure is installed on the pcb board, contact 23 is relative with the circular touch-switch 11 of pcb board, the direction that may occur big deflection when the long limit bearing of trend of contact 23 should be pressed with button at this moment, for example long limit of press-key structure 22 (if button has long limit) unanimity.

With reference to shown in Figure 5, when an end of press-key structure 22 was pressed, although produce bigger deflection, its contact 23 can contact with the touch-switch 11 of pcb board.

Therefore, the embodiment of the described press-key structure of the utility model, make that can both reach key contacts when pressing in any position of button fully contacts with the pcb board touch-switch and make abundant conducting, can not produce the situation that the excessive bullet that can't push button, reduce the damage of key contacts and touch-switch, allow make client more cosily use product.

Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
