CN2514412Y - Switch key for computer keyboard - Google Patents

Abstract

The utility model discloses a computer keyboard switch key which is matched with a key switch. The utility model is composed of a crossed connecting body and a pedestal, wherein the side wall of the pedestal of the key is provided with a salient paling which is close to the upper edge of the side wall. When the computer keyboard switch key is used, the key is positioned in the key switch. When the key moves downward, the salient paling at the side wall of the pedestal can make the elastic sheet at the side surface of the key switch be strutted. When a hollow column body of a key cap is pressed to the bottom, the hollow column body just keeps away from the elastic sheet; thereby, the elastic sheet is guaranteed to be not squeezed. The utility model has characteristics of flexible key press, firmness, durability and long service life. In addition, the sound produced by pressing the key is silvery.

Description

The Computer keyboard switch button

Technical field

The utility model relates to a kind of computor-keyboard pushbotton switch, especially a kind of mechanical type keyboard switch.

Background technology

At present, common computor-keyboard pushbotton switch, its structure as shown in Figure 1, keyswitch is connect electroplax, spring, button, shell fragment and loam cake and is formed by pedestal, two, two lead-in wires that connect electroplax are passed by the bottom of pedestal, and spring is connected on the newel of loam cake and button, and certain mobile space is arranged when making button pressed, inboard connect electroplax and shell fragment all bends inwards, hook joint is on the lower limb of button.Two parts that button is formed in one, top are divided into cross connector, are used to connect button cap, and the bottom is divided into base.Its weak point is the cross button that is adopted, and when pressing downwards, the shell fragment of both sides can be pushed in the hollow cylinder bottom of the keycap that is connected, and easily causes the distortion of shell fragment, so that button is dumb, and sound is gently crisp inadequately.

Summary of the invention

The purpose of this utility model is to provide a kind of cross button, can protect the contact in the computor-keyboard pushbotton switch not to be squeezed, and button is flexible, sound is gently crisp and long service life.

For achieving the above object, solution of the present utility model is: a kind of Computer keyboard switch button, and cooperate keyswitch to implement, form by cross connector and base, wherein, the button base side wall is provided with protruding wall, and approaches the coboundary of sidewall.

Adopt said structure, button is built in the keyswitch.When button moved down, the protruding wall of its base side wall strutted the shell fragment of keyswitch side, when the hollow cylinder of keycap is pressed the bottom, avoided shell fragment just, had guaranteed that shell fragment is not extruded.The utlity model has button flexibly and the sound that is produced when pressing button gently crisp, have the characteristics of firm and durable, long service life.

Embodiment

As shown in the figure, the utility model provides a kind of Computer keyboard switch button 1, cooperates keyswitch 2 to implement, and button 1 is formed in one, and is made up of cross connector 11 and base 12, and base 12 sidewalls are provided with protruding wall 121, and approach the coboundary of sidewall.

Above-mentioned button 1 is built in the keyswitch 2, connect electroplax 22,23, a spring 24, a shell fragment 25 and a loam cake 26 combinations with a pedestal 21, two, the connector 11 of button 1 is passed the center pit of pedestal 21, protrusion is outside pedestal 21, two connect electroplax 22,23 and shell fragment 25 is inserted respectively in the clip slot 211 at pedestal 21 two ends, and collude respectively on the sidewall lower limb that is against button base 12 on the top that connects electroplax 22,23 and shell fragment 25.Spring 24 1 ends are set on the newel 13 of button base 12, and the other end is set on the newel of loam cake 26 central portions, and two lead-in wires that connect electroplax 22,23 pass loam cake, and loam cake 26 is fastened togather with pedestal 21.

Open column 31 in the keycap 3 is enclosed within on the cross body connector 11 of button.When pressing keycap 3, button 1 moves down, as shown in Figure 5, the shell fragment 25 of side breaks away from the lower limb of button base 12, and on top edge is strutted by protruding wall 121, at this moment, the open column 31 of keycap 3 is also along with button 1 moves downward, and the bottom of straight-through pedestal 21 is because of shell fragment 25 is strutted by the protruding wall 121 of button 1, the bottom of open column 31 can not contact with it, avoids being extruded.Unclamp keycap 3, under the restoring force effect of spring 24, button 1 resets.

Claims (1)

1, a kind of Computer keyboard switch button cooperates keyswitch to implement, and is made up of cross connector and base, and it is characterized in that: the button base side wall is provided with protruding wall, and approaches the coboundary of sidewall.
