Abstract
The utility model discloses a television button device comprising a front shell, a button switch and a circuit board. The button switch comprises a bridge cap, a bridging and an elastic unit which are connected orderly from outside to inside, the elastic unit vertically faces the top surface of the circuit board, and a through hole is arranged at the position where the top surface of the circuit board corresponds to the elastic unit vertically. The external diameter of the elastic unit is greater than the diameter of the through hole, and an outward notch is arranged at the edge of the through hole. The elastic unit is a spring and/ or an elastic plastic cement, and the circuit board is a flexible circuit board. The front shell is equipped with a penetrating hole for accommodating the bridge cap, and the bridge cap penetrates the penetrating hole. The bridge cap of the utility model is connected with the bridging via the elastic unit, so that the bridge cap, the bridging and the elastic unit are firm and do not fall off; by arranging the through hole at the position where the top surface of the circuit board corresponds to the elastic unit vertically, the elastic unit and the circuit board are firm and do not fall off, the button assembly working procedures and the production cost are reduced, and the operation is simple and convenient. The television button device of the utility model can be used in various types of television buttons.
Description
Technical field
The utility model belongs to field of television, more specifically relates to a kind of television set key device.
Background technology
The TV machine is very universal, becomes one of electrical equipment of family's indispensability.Because utilization rate is very frequent, so higher to the button quality requirement of television set.And the television set button is generally that Flexible element simply contacts with bridge plate and without any fixture, is easy to cause Flexible element to come off at present, when assembling, particularly refills timing after laid-up to be easy to come off, and difficulty is installed; And the Flexible element of traditional television set button is also simply to contact with circuit board and without any fixture, also be easy to cause Flexible element and other key component to come off, also easily come off between Flexible element and circuit board, be difficult for installing, often first to and then assemble with other securing members fixing circuit board as first in screw, operation is many, and efficient is low.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of television set key device, realizes that Flexible element is not easy to come off, and easy to assembly, and operation is few, and efficient is high, and cost is low.
For achieving the above object, the technical scheme that adopts of the utility model is:
A kind of television set key device comprises fore shell, key switch and circuit board, and described key switch comprises bridge cap, bridge formation and the Flexible element that ecto-entad connects successively, and described Flexible element and board top surface are vertically opposite.
More excellent, described board top surface and Flexible element be vertically opposite should locate to be provided with a through hole, and described Flexible element external diameter is greater than through-hole diameter.
More excellent, described through hole edge is provided with outside recess.
More excellent, described Flexible element is spring and/or Elastic plastic-rubber.
More excellent, described circuit board is flexible PCB.
More excellent, described circuit board is screwed on a base plate.
More excellent, described fore shell is provided with the perforation of holding the bridge cap, and described bridge cap passes perforation.
After adopting technique scheme, its beneficial effect is: the bridge cap is connected with bridge formation by Flexible element, realizes firmly and not coming off between bridge cap, bridge formation and Flexible element; Be provided with a through hole by board top surface and vertically opposite should the locating of Flexible element, realize firmly and not coming off between Flexible element and circuit board, and reduce the key assembling operation, simple to operation, improved operating efficiency, reduced production cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
as shown in Figure 1, a kind of television set key device of the utility model, be provided with fore shell, key switch and circuit board 12, key switch comprises the bridge cap 15 that ecto-entad connects successively, bridge formation 14 and Flexible element 13, one end of Flexible element 13 is relative with circuit board 12 planes, circuit board 12 end faces and Flexible element 13 be vertically opposite should locate to be provided with a through hole 121, Flexible element 13 external diameters are greater than through hole 121 diameters, through hole 121 edges are provided with outside recess 122, Flexible element 13 is spring, it can be also Elastic plastic-rubber, circuit board 12 is that flexible PCB is better, circuit board 12 can be screwed on a base plate 11, fore shell is provided with the perforation of holding bridge cap 15, bridge cap 15 passes perforation, Flexible element 13 is outstanding to circuit board 12 directions, the through hole 121 that arranges with Flexible element 13 places of offseting on circuit board 12 can be also the projection that arranges for inner concavity or surrounding, like this when by breaking the bridge cap 15, Flexible element 13 is held to be pressed in through hole 121 fix and be electrically connected to, and when bridge cap 15 ejects (when closing), Flexible element 13 is electrically connected to disconnection with circuit board 12, but Flexible element 13 is still fixed in through hole 121 and can not moved and come off to circuit board 12 planes peripheries, assembling process can not need other securing members such as screw to carry out first fixing circuit board 12, only need circuit board 12 and Flexible element 13 are socket-connected and get final product.
During work, by breaking the bridge cap 15, bridge formation 14 steadily moves inward bridge cap 15, and Flexible element 13 is pressed into fixing in through hole 121 and is electrically connected to circuit board 12.And when quitting work, ejecting bridge cap 15, Flexible element 13 is electrically connected to disconnection with circuit board 12, but Flexible element 13 is still fixed in through hole 121 and can not moved and come off to circuit board 12 planes peripheries.Realize that so Flexible element 13 firmly and not comes off, and reduce the key assembling operation, simple to operation, improved operating efficiency, reduced production cost.
Above-described is only the preferred implementation of a kind of television set key device of the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
