Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As Fig. 1-shown in Figure 8, a kind of noise reduction does not have the push-button switch of rocking, comprise button cap 1, transmission body 2, housing 3, flexible keypad 4, circuit board 5 and base 6, wherein: the top clamping of button cap 1 and transmission body 2, the bottom of transmission body 2 be placed in the housing 3 and with housing 3 clampings, the top clamping of the bottom of housing 3 and base 6, flexible keypad 4 and circuit board 5 are fixed in the top of base 6 from top to bottom successively and are in the housing 3.
The top clamping of button cap 1 and transmission body 2, button cap 1 is the pressing part of hand;
Be respectively equipped with a conduit 15 on the lateral wall of housing 3 front, rear, left and right, be respectively equipped with a lead 11 that matches with U type gathering sill 10 on the madial wall of housing 3 front, rear, left and right, so that transmission body 2 slides up and down, also be respectively equipped with two connecting holes 13 with base 6 clampings in the bottom of housing 3 forward and backward lateral walls in housing; Be respectively equipped with two and be located at the card fast 9 that matches in the front side wall of transmission body 2 and the right-angled trapezium hole on the rear wall on the front side wall of housing 3 and the rear wall, card in the present embodiment fast 9 is the rectangle fixture block, the trans D of rectangle fixture block is greater than the trans D of quadrilateral hole 7 bottom end openings, and the volume of rectangle fixture block is less than the volume in right-angled trapezium hole in addition.
Being shaped as of fixture block 9 can also be circle in the present embodiment.
As can be seen from the above embodiments, the utility model is by being provided with special quadrilateral hole 7 on transmission body 2, and the hypotenuse on the quadrilateral hole 7 17 is made as hanging shape, the fixture block 9 that matches with quadrilateral hole 7 is set on housing 3, be arranged to special elasticity inclined-plane line contact stop structure, when transmission body 2 returns, be located at the hypotenuse 17 of the quadrilateral hole 7 on the transmission body 2 and contact, form the zero clearance of horizontal direction, solved the problem of rocking of button initial position with fixture block 9 on being located at housing 3.Simultaneously in the moment that transmission body 2 returns stop, the contact site of the fixture block 9 on being located at the hypotenuse 17 of the quadrilateral hole 7 on the transmission body 2 and being located at housing 3 contacts for linear, has reduced the area that transmission body 2 and housing 3 collide; And the hypotenuse 17 of being located at the quadrilateral hole 7 on the transmission body 2 is the elastic cantilever structure, plays cushioning effect, thus the noise problem that collision causes easily when having reduced return.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
