Abstract

The utility model relates to a keyboard button with a novel structure, which comprises a cover body (1), a base (2), a press body (3), springs (4) and spring pieces, wherein, the side faces of the spring pieces can generate sound (5). A small hole is arranged in the middle below the base (2), and the spring piece, the side face of which can generate sound (5), is attached to one inner side of the base (2). The spring (4) is positioned above the small hole in the base (2), and the base (2) is provided with a convex place. The fixed spring (4) and the press body (3) are positioned above the spring (4), and the lower end of the press body (3) is provided with a small column. The small column body passes through the middle of the spring (4). The press body (3) is fixed in the middle of the spring (1) and the base (2). The utility model has the advantages of simple structure, a few fittings, low manufacture cost and convenient maintenance, and is used for the keyboard button of a conductive film structure.

Description

The new construction keyboard

The utility model relates to a kind of keyswitch, is particularly useful for the button of computer keyboard.

Conventional computer keyboard key, its structure as shown in Figure 1 and Figure 2, by cover body (1), (7), form by body (2), spring (3), shell fragment (6) and guide card (4), (5), be set as two clip slots in the cover body, be respectively forward and backward clip slot, integrated plastic cement tab forms at interval two clip slots in the body by putting, make preceding guide card (4) be inserted in preceding clip slot, back guide card (5) is inserted in the back clip slot, this kind structure needs composition element many, material cost height not only, the manufacturing cost height, and also it is also quite high to assemble spent manpower.

The purpose of this utility model provides a kind of simple in structure, the new construction keyboard that production cost is low.

Structure of the present utility model comprises cover body (1), base (2), presses body (3), spring (4) and side are rung shell fragment (5), one aperture is arranged in the middle of the below of base (2), side is rung the inboard that shell fragment (5) is attached to base (2), spring (4) places the top of the interior aperture of base (2), base (2) has a protruding position, fixing spring (4), there is a small column top that places spring (4) by body (3) by the lower end of body (3), small cylinder penetrates the centre of spring (4), by body (3) by putting body (1) and base (2) is fixed in therebetween.

The utility model has the advantages that simple in structurely, spare and accessory parts are few, and production cost is low, and is easy to maintenance, is applicable to the keyboard of conducting membrane structure.

Below in conjunction with drawings and Examples structure of the present utility model is further described.

Fig. 1 is the exploded view of conventional each parts of button.

Fig. 2 is conventional press-key structure cut-open view.

Fig. 3 is the exploded view of the utility model parts.

Fig. 4 is the utility model structure cut-open view.

By accompanying drawing (3), (4) as can be known, structure of the present utility model comprises cover body (1), base (2), press body (3), spring (4) and side are rung sheet (5), one aperture is arranged in the middle of the below of base (2), side is rung the inboard that shell fragment (5) is attached to base (2), spring (4) places the top of the interior aperture of base (2), base (2) has a protruding position, fixing spring (4), place the top of spring (4) by body (3), there is a small column lower end by body (3), small cylinder penetrates the centre of spring (4), be fixed in therebetween by spring (1) and base (2) by body (3), be provided with the groove position, play a part with to put body (1) fixing by en on the two sides of body (3), be fixed in therebetween by cover body (1) and base (2) by body (3), press body (3) can elastic force with spring (4) pressurized on, lower slider.

After pressing body (3) pressurized, move down by body (3), its side rings sheet (5) and spring (4) can be pressed off and depress, and sense of hearing and hand sense of touch are arranged, pass the interstitial hole position of base (2) simultaneously by the terminal small column of body (3), press to contact on the conductive film of outer circuit grillage, two conductive films that separate are connect to conduct, after relying on the elastic force of spring (4) to withdraw from by body, conductive film is got back to former disconnected position, keeps off-position.Cover body (1), base (2), make by plastic cement by body (3).
