When finger presses the button cap 30 towards the direction of button connector 40, the button cap 30 drives the button
Connector 40 is moved along through hole 15 towards the direction of button conducting piece 50, and then is promoted the button conducting piece 50 and described pressed
Key switch 60 is moved, and such key switch 60 triggers the connection of a certain functional circuit, so as to realize a certain specific function.
Please join Fig. 3, in the present embodiment, two guide pads 11 and two locating parts 13 are convexly equipped with the key base 10.It is each
Individual guide pad 11 is correspondingly arranged with a locating part 13, is close to the through hole 15 and sets, and is relatively arranged on the through hole 15
Opposite sides.It is each when the button cap 30 and the button connector 40 are installed in the through hole 15 of the key base 10
Individual guide pad 11 and its corresponding locating part 13 are partly placed in second pilot hole 307 of the button cap 30 and court
The direction projection of the key switch 60；It is the button connector between each guide pad 11 and its corresponding locating part 13
40 extension 43.In this way, the button connector 40 can be limited between the guide pad 11 and locating part 13 well.
As shown in figure 3, the guide pad 11 has a confined planes 111 concordant with the hole wall (not shown) of through hole 15 and court
To the spigot surface 113 of the key switch 60.So-called confined planes 111 are just to the extension 43 of the button connector 40.It is described
The relative limit face 111 of spigot surface 113 inclines.In the present embodiment, the company of being also associated between the spigot surface 113 and confined planes 111
Junction 115, the joint face 115 is vertical with the confined planes 111.In the present embodiment, the spigot surface 113 and 111 one-tenth of confined planes 45
The angle of degree.During assembling, the spigot surface 113 can be attached in the inclined plane 503 of the button conducting piece 50, make key base
10 slided towards the mounting seat 80 along the inclined plane 503 of the button conducting piece 50 the button conducting piece 50 is pushed it is described
Between button connector 40 and the key switch 60.In this way, the button conducting piece 50 more easily can be pushed into described pressing
Be bonded between fitting 40 and the key switch 60, it is ensured that the button conducting piece 50 is pushed in place, and will not cause it is described by
Key conducting piece 50 too extrudes the button connector 40.
When assembling the button module 200, the button connector 40 is installed on the assembling of the button cap 30 first
In groove 305, the button cap 30 and the button connector 40 are then loaded logical from the side of the through hole 15 of the key base 10
In hole 15；Then the key switch 60 and the button conducting piece 50 are installed in mounting seat 80, it is concretely described
Key switch 60 is installed in the stopper slot 801, and the button conducting piece 50 is sheathed in the lead column 800；Then will
Key base 10 is fastened in mounting seat 80, and specially the spigot surface 113 of key base 10 is along the button conducting piece 50
Inclined plane 503 is slided towards the mounting seat 80, so as to key base 10 be fastened with the mounting seat 80, and make it is described by
Key conducting piece 50 is pushed between the button connector 40 and the key switch 60 and assembled in place.
It should be understood that the spigot surface 113 can be adjusted as needed with the angle of confined planes 111, it is ensured that can be compared with
Easily the button conducting piece 50 is pushed between the button connector 40 and the key switch 60.
The button connector 40 has certain elasticity, is made of elastomeric material.It is described by being bonded in the present embodiment
Fitting 40 is made of polyurethane elastomer rubber.Preferably, use hardness to be made up of 65 degree of polyurethane elastomer rubber, such as
, in pressing, the compression compression deformation of the button connector 40 can prevent from damaging the key switch 60 by pressure, and can absorb the system of part for this
Tolerance and build-up tolerance are made, while providing the pressing feel of button.Assemble when in place, the button connector 40 is by the button
The decrement of the compression of conducting piece 50 is only 0.15 millimeter.
The button conducting piece 50 is pushed when between the button connector 40 and the key switch 60, is pressed by described
The push-in extruding of key conducting piece 50, the button connector 40 can be towards the extruding of the direction of the locating part 13, said locating part
13 can support the button connector 40, it is to avoid the excessive distortion of button connector 40 deformation.
As shown in figure 3, in the present embodiment, the locating part 13 includes spaced two limiting sections 131.It is appreciated that
, the shape of the locating part 13 is not limited to two limiting sections 131 of this case diagram, it is also possible to be arranged to a limiting section, only
Can play and support the button connector 40, it is to avoid the excessive distortion of button connector 40 deformation both may be used.
It should be understood that the quantity of the button conducting piece 50 and key switch 60 is not limited to be set to two, can also set
It is set to one and two or more.Then corresponding, guide pad 11, the quantity of locating part 13 are according to the button conducting piece 50 and button
The quantity of switch 60 is adjusted, changes.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although reference
Preferred embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to of the invention
Technical scheme is modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
