Embodiment
It is clearer for the technical scheme and the technique effect that reaches that make technical problem that the utility model solves, use,
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Referring to Fig. 6 to Figure 10, a kind of anti-clamping stagnation button, including housing 1, button 2, driving member 3 and printed board 4, housing 1 be
The hollow cavity of both ends open, button 2 and driving member 3 are respectively positioned in housing 1 and can slided between both ends open, button 2
Just it is located at the bottom end opening of housing 1 facing to the top end opening of housing 1, printed board 4；Also include protective case 5, the buckle closure of protective case 5
In the top of housing 1, spacing hole 51 is offered on protective case 5, the edge of spacing hole 51 is provided with the annular limit upwardly extended
Position flange 52；Lug boss 21 on button 2 is located in spacing hole 51, and the side of lug boss 21 and the inner surface of defining flange 52 have
Gap.The size in gap is 0.2~0.4mm.In pressing keys 2, the side of lug boss 21 and the inner surface of defining flange 52
Random contact, it is also possible to do not contact.
The edge of protective case 5 is provided with the flange 53 of downward bending, flange 53 and the clamping of housing 1.Flange 53 is provided with
At least one neck 531, the correspondence position on housing 1 in neck 531 are provided with the buckle 11 that is engaged with neck 531.Protection
Set 5 can not distort, button bit fixation non-loosening.
Fixed part 12 is provided with two relative lateral surfaces of housing 1, the first fixing groove is offered on fixed part 12
121, for button to be fixed on into installation panel 6.The position that the edge of protective case 5 is in the face of fixed part 12 is provided with level
Extension 54, second fixing groove 541 relative with the first fixing groove 121 is offered on extension 54.First fixing groove 121 and
Two fixing grooves 541 are U-type groove.Mounting hole 61 and butt-joint stud 62, the first fixing groove 121 and are provided with installation panel 6
Two fixing grooves 541 can be set on butt-joint stud 62, then fixed again with nut.
Protective case 5 is made up of the shaping of stainless steel material mould punching.The thickness of protective case 5 is 0.2~0.3mm.Protection
Set 5 as far as possible do it is thin, to reduce the gap between active key 2, protective case 5 and the three of button installing hole 61.Defining flange 52
Inner surface does polishing, ensures smooth.Caused burr in punch forming is removed, prevents protective case 5 and the clamping stagnation of button 2.
Driving member 3 is provided with spring between button 2 and printed board 4 between driving member 3 and printed board 4；Printed board 4
At least one touch-switch is provided with towards the surface of driving member 3 and is electrically connected with touch-switch multiple equally distributed
LED, button 2 can drive the slide trigger touch-switch of driving member 3, lightening LED lamp.
During assembling, first driving member 3 and button 2 are sequentially loaded into housing 1, then by protective case 5 and the clamping of housing 1, this
When, the lug boss 21 of button 2 is located in spacing hole 51, and the side of lug boss 21 contacts with the inner surface of defining flange 52；Then
Printed board 4 at spring and the bottom end opening of housing 1 is installed, button is completed；By the first fixing groove 121 and the second fixing groove
541 are set on the butt-joint stud 62 of installation panel 6, now the outer surface of defining flange 52 of protective case 5 and the installation of panel
The inner surface contact in hole 61, is then again fixed button with nut, and simple in construction, packaging efficiency is high.
In use, pressing button 2, driving member 3 is driven to slide, spring transmission part 3 compresses, and reaches certain position, transmission
Part 3 triggers the touch-switch in printed board 4, and LED is bright, and button 2 is luminous, and tactile depressing action is completed；Button 2 is unclamped, spring will pass
Moving part 3 is upspring, and button 2 resets；In the process, protective case 5 and the geo-stationary of mounting hole 61.
Protective case prevents the button of button directly to coordinate with mounting hole, the problem of avoiding friction from causing clamping stagnation, using more
It is convenient；Attractive in appearance during guarantee button installation, button assembling required precision is not high, easily fabricated and easy for installation.No matter butt-joint stud
Big deviation is whether there is, protective case can make button relative with mounting hole placed in the middle, and button is in the defining flange with protective case
Side throwing smooth surface does relative motion, the mounting hole geo-stationary of protective case and installation panel, is not in thus that button blocks
(stagnant) phenomenon.
Embodiment of above simply elaborates general principle and characteristic of the present utility model, and the utility model is not by above-mentioned reality
The mode of applying limits, and on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change and change,
These changes and modifications are both fallen within claimed the scope of the utility model.The utility model requires protection scope is by appended
Claims and its equivalent thereof.
