Description
Technical field
The utility model relates to panel TV field, particularly relate to a kind of for panel TV profile as the mechanical key structure of piano.
Background technology
Along with the diversified trend of panel TV set outward appearance in recent years, on television set, key support is as the requisite part of outward appearance, and button form is also more and more diversified.How, in guaranteeing usability, realize the variation of key support form, proposed more and more higher requirement for the detailed design of key support.
Utility model content
The purpose of this utility model is for addressing the above problem, and proposes a kind of structure of novel mechanical button, is made up of key support and printed board.Between key support and printed board, adopt clamping form to connect.
The utility model adopts following technical scheme: a kind of structure of mechanical key, comprise key support and printed board, and the corresponding position, the button back side on described key support arranges printed board, and described printed board is fastening by it by being fixed on snap fit on key support.
In technique scheme, the described button back side is provided with five place's snap fits, in described printed board, offers square hole with snap fit corresponding position.
In technique scheme, it is in a symmetrical arrangement that described snap fit is arranged between button both sides.
In technique scheme, the described key support back side is provided with locating button, and the described printed board position corresponding with locating button is provided with breach.
The beneficial effects of the utility model: key support adopts common ABS material compacting, outward appearance shape is as key, key mapping is cantilever design, utilize suitable gap between the certain wall thickness of cantilever root and key, guarantee the good certain wall thickness of effect utilization and the suitable gap of pressing, guarantee the good effect that presses, the outward appearance that meets present panel TV is beautified demand.
Accompanying drawing explanation
The present invention will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is connection diagram in the utility model;
Wherein: the 1st, key support, the 2nd, printed board, the 3rd, locating button, the 4th, snap fit.
Embodiment
As shown in Figure 1, the utility model comprises key support 1 and the printed board 2 that is arranged on key support 1 back side; Key support 1 back side is provided with locating button 3, and buckle 4 is arranged at the both sides of key support 1 along rectangular direction, and locating button 3 is arranged on the two ends of key support 1, squarely; The position of printed board 2 and bayonet socket 4 correspondences is provided with square hole, and is provided with breach on printed board 2 position corresponding with locating button 3.
In the time that needs are installed printed board 2, to the position of its printed board 1 and locating button 3, firmly, downwards by printed board 2, snap fit 4, by stress deformation, outwards opens, and through the square hole in printed board 2, then snap fit 4 reduces, and locks printed board 2.
When practical the utility model, depress key support keyboard, transmit strength to touch-switch by key contacts, while unclamping button, by the reset force reinstatement state of button cantilever and touch-switch.
Key support profile shape, as piano keyboard, adopts common ABS injection mo(u)lding, and overall wall thickness is 1mm, and for guaranteeing appearance looks elegant, between key support, fit clearance is controlled at 0.5mm; For guaranteeing the enough elasticity of key support, key support partial wall b reduces to 1mm, has both guaranteed injection moulding requirement, has guaranteed again the life-span of button.
Disclosed all features in this specification, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
