Embodiment
With reference to the accompanying drawings preferred implementation of the present invention is elaborated.
Fig. 1 and Fig. 2 a are decomposing schematic representation and the cutaway views of push-button switch device of the present invention, and push-button switch device of the present invention comprises the hexahedron shell 10 with inner space.Shell 10 is made by injection molding forming method by insulating resin, and the top opening to be arranging parts in inside, set up parts after, the cover plate 20 that utilizes metal material to make covers its opening portions.
Be provided with the first fixed terminal 12 of on-off action and the second fixed terminal 13 in the shell 10 and be connected to connect or disconnect above-mentioned the first fixed terminal 12 and the second fixed terminal 13 to realize the movable terminal 14 of switching function.
The first fixed terminal 12 and the second fixed terminal 13 are made by conducting metal, such as Fig. 1 and shown in Figure 3, and together moulding when shell 10 is carried out injection mo(u)lding, and be embedded in the shell 10.The first fixed terminal 12 and the second fixed terminal 13 comprise respectively outside terminal 12a, 13a, and being connected with external power source, described outside terminal 12a, 13a exposes and be arranged on the below of shell 10 two sides; Also comprise respectively brace 12b, 13b, being connected with above-mentioned movable terminal 14, described brace 12b, 13b exposes and be arranged on shell 10 inner bottom surface.Wherein, the brace 12b of the first fixed terminal 12 is arranged on shell 10 bottom surface middle positions, and the brace 13b of the second fixed terminal 13 arranges 2 altogether, is separately positioned on dual-side edge, shell 10 bottom surface.
Pressurized operation to above-mentioned movable terminal 14 apex 14a is realized by the cover plate 20 of covering shell 10 opening portions.
As long as press cover plate 20, make it that strain occur downwards, strain will occur downwards in middle body, and stud bump 21 is mobile downwards, finally makes stud bump 21 press the apex 14a of movable terminal 14.When stud bump 21 is pressed movable terminal 14, can concentrate pressing force, make the apex 14a of movable terminal 14 that sufficient strain occur downwards.
In addition, the fixed structure of shell 10 and cover plate 20 is as follows.The marginal portion of cover plate 20 is formed with a plurality of U-shaped flexible fastening sheets 22, and the opening portion upper surface of shell 10 is formed with a plurality of holddown grooves 11 that can insert and fix above-mentioned flexible fastening sheet 22.
Wherein, above-mentioned flexible fastening sheet 22 and holddown groove 11 all equidistantly form 4 with 90 degree intervals, and the open-ended interval of above-mentioned U-shaped flexible fastening sheet 22 is greater than the width of the holddown groove 22 of the shell corresponding with it 10.The open-ended interval of flexible fastening sheet 22 is larger, and when flexible fastening sheet 22 was inserted into holddown groove 22, its elastic recovering force was also just larger, thus the stationary state between raising and holddown groove 22 sidewalls.
In addition, the present invention has adhered to the diaphragm 30 that the synthetic resin of thin layer is made at the upper surface of the opening portion of shell 10 upper surface and cover plate 20 by binding agent, prevents that the foreign matters such as dust or moisture from entering shell 10 inside.
In addition, as a distortion example of above-mentioned cover plate 20, as shown in Figure 4, be preferably in and form a plurality of through holes 23 between its edge part and the stud bump 21, in order to strain occurs.Above-mentioned a plurality of through hole 23 uniformly-spaced is arranged on the circumference centered by the stud bump 21 of central authorities, preferably is arranged on a plurality of circumference along radial direction interlacedly, and the shape of through hole 23 is along the circumferential direction slotted hole preferably.
Below, the operation principle of the present invention with said structure is described.
Shown in Fig. 2 a and Fig. 2 b, for carrying out button operation, press the central authorities of cover plate 20, because the edge of cover plate 20 is fixed, strain will occur downwards in middle body, and stud bump 21 contacts and it is pressed with the apex 14a of movable terminal 14 to movable terminal 14 side shiftings.
Because cover plate 20 is made by the thin metal blank that can deform under self elastic reaction and restore, so strain can very successfully occur.
As mentioned above, the apex 14a pressurization of 21 pairs of movable terminals 14 of stud bump of cover plate 20, shown in Fig. 2 b, strain occurs downwards in the apex 14a of movable terminal 14, contact with the brace 12b of the first fixed terminal 12 that arranges on the shell 10, the first fixed terminal 12 and the second fixed terminal 13 are connected mutually.
At this moment, the pressurization projection 36 of cover plate 20 will make pressure concentration at the apex 14a of movable terminal 14, therefore can guarantee that sufficient strain occurs the apex 14a of movable terminal 14 downwards.
Then, remove the pressure to cover plate 20, movable terminal 14 and cover plate 20 be involution original position under self elastic recovering force effect respectively.Like this, the apex 14a of movable terminal 14 will separate with the brace 12b of the first fixed terminal 12, makes between the first fixed terminal 12 and the second fixed terminal 13 to disconnect.
As mentioned above, push-button switch device of the present invention is by realizing can repeatedly carrying out switching manipulation to the switching function of the apex 14a pressurization of movable terminal 14 to the pressing operation of cover plate 20.
In addition, the present invention can finish the assembling operation of shell 10 and cover plate 20 very simply, easily.Namely, as long as the U-shaped flexible fastening sheet 22 of cover plate 20 is inserted in the holddown groove 11 of shell 10, flexible fastening sheet 22 will produce elastic recovering force when shrinking, make flexible fastening sheet 22 be close to the sidewall of holddown groove 11 by above-mentioned elastic recovering force, keeps the stationary state of cover plate 20 and shell 10.
More than the preferred embodiment for the present invention is had been described in detail, but the present invention is not limited to above-mentioned execution mode, under the prerequisite that does not break away from the technology of the present invention thought and claim scope, association area practitioner can carry out numerous variations, distortion or displacement, and these execution modes all should belong to the scope of claim of the present invention.
