For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of structural improvement of button, the primary structure of its button includes the button in the button socket that is inserted on the keyboard body, and be engaged in and be provided with the elasticity coupler body that can be subjected to compressing of button and make the conducting of circuit board contact between circuit board and button, at the elastic container portion inner face top of elasticity coupler body and be provided with and couple salient point, with by coupling that salient point contacts with contact on the circuit board and the conducting that constitutes this contact use and send the pairing signal of this button, and when user's release is touched the pressure of button, it plays the elasticity coupler body and can form an elastic reaction and return back to original shape, makes to end sending of signal; It is characterized in that: the elastic container portion root edge of this elasticity coupler body is formed with some breach, with when its elasticity coupler body is rebounded original shape via the elastic force effect of elastic container portion, its breach can constitute one allows air enter duct between elasticity coupler body and circuit board, can allow the elasticity coupler body return back to original shape really to avoid producing vacuum phenomenon.
Another feature of the present utility model is that the button socket of this keyboard forms useful trepanning and slot with guiding button knee-action, button then cooperates and is formed with a post that compresses that can penetrate trepanning, and prevent the grab plate that gets loose with formation in order to insert slot, use and button can be limited on the main body of keyboard.
Another feature of the present utility model is that this elasticity coupler body and button compress the joint of post, form the socket end and the covered joint seat of tool positioning action respectively, the elasticity coupler body can be touched and really downwards action, to avoid causing phenomenon crowded, that fill and be out of shape with the pressure of button.
The another lower edge that is characterised in that the button socket of this keyboard of the present utility model is formed with a frame cover portion in order to compress the next place of post at button with the elasticity coupler body is spacing, the main body of this keyboard can cooperate by the covering of upper and lower cover, and constitutes the complete structure of integral keyboard.
The utility model has the advantages that by elastic container portion root edge and be formed with some breach in the elasticity coupler body, with when its elasticity coupler body is rebounded original shape, its breach can constitute one allows air enter duct between elasticity coupler body and circuit board, can allow the elasticity coupler body return back to original shape really to avoid producing vacuum phenomenon, and the joint that compresses post at its elasticity coupler body and button, form the socket end and the covered joint seat of tool positioning action respectively, the elasticity coupler body can be touched and really downwards action with the pressure of button, crowded to avoid causing, the phenomenon of filling and being out of shape, the sense of tangible paragraph difference is arranged when allowing the user beat button, not only can increase the comfortableness of use, and can increase the speed of beaing button.
