The nameplate 2 is integrally punched with a pair of positioning portions 5 at a position for mounting the button 4. Positioned by a balance foot 6 of a set of vulgar scissors feet. The circuit film 1 is provided with an electrical contact h at a position for mounting the button 4, and an elastic coupling body 8 is disposed between the electrical contact 7 and the button 4. When the operator touches the button 4 downward, At the same time, the elastic coupling body 8 can be pressed to form the electrical contact 7 of the circuit film i, and the elastic coupling body 8 is elastically deformed to generate a force for the button 4 to be reset upward. The balance foot 6 maintains the upper and lower movements of the button 4. balance. However, the above-mentioned keyboard has the following disadvantages: The circuit film 1 is relatively disposed on the pure 2 and the button 4, and the perforation 9 is additionally provided for the positioning and sliding of the positioning portion 5 through the rod 6 to avoid Balance foot 6 complex: G, short circuit of electrical contact 7, so that the processing work tends, and the traditional, relatively increased overall manufacturing of the keyboard, especially 1 Ray Road old 1 is not subject to any shielding, easier to derive waterproof: Can = M345289 questions. 2. The positioning part 5 is damaged on the nameplate 2, and the assembly work is complicated. 3, circuit film! The circuit design on the line is to make the overlap line or to solve the problem by using a jumper. The problem of flying fresh is 'increasing the overall keyboard 4, the circuit film 1 is directly set on the ton 2, and the circuit film has the elastic coupling body 8, which balances the interference of the foot rod 6 and the connector 8, so it will be strong _ difficult 7 . The time is subject to elasticity. [New content] ‘Lie’s is to change the above-mentioned shipbuilding::=:Γ can simplify the assembly method, reduce the manufacturing cost and the keyboard structure that can achieve better waterproof function. The main system of the keyboard with -m is set up from the bottom to the bottom according to the _ mounting position, below the circuit film circuit film, the _ branch #=^.^^ struts are placed above the film. The clamp plate is connected to the electrical contact with the electrical contact: the plate for one plate has: set and use the space a 7 and the position of the electrical contact? (, elastic coupling _ part relative stretch The bit plate is in contact with the 6 M345289 key. The effect of this creation is that the positioning parts of the positioning plate are plastic-body-shaped dental holes and cause the original. The core is low-processing system, and the other functions are The second one is that the circuit film is set under the positioning plate and the manufacturing cost is 2. The exposed perforation of the mosquito part is opened, so that the third effect of the work can be greatly reduced, and the circuit film is set on the positioning plate and the support is flat = The contact between the member and the flat rod can effectively avoid the function of the circuit board m2. The electric_is difficult to be placed on the positioning plate and the support θ, and can be shielded by the positioning plate and the support plate, so that a better waterproof effect can be obtained. m [Implementation] The characteristics of this creation can be found in the drawings and the details of the examples. The description is clearly understood. As shown in the second to fourth figures, the keyboard improved structure package of the present invention includes: a circuit film 10, a support plate 20, a positioning plate 3〇, and a plurality of buttons 40, The plurality of balance legs 5 〇 and the plurality of elastic coupling bodies 6 〇; wherein: the circuit film 10 is provided with electrical contacts 11 at positions corresponding to the buttons 40; the support plate 20 is disposed under the circuit film 10, To support the circuit film; the positioning plate 30 is disposed above the circuit film 1 ,, which is provided with a through hole 31 at a position corresponding to the electrical contact ,, and a plate surface corresponding to the M345289 mounting button 40 at the positioning plate 3 〇 The positioning portion 32 is disposed at a position, and the through hole 31 may be a square hole or a circular hole corresponding to the elastic coupling body 6 (as shown in FIG. 6). The plurality of balance legs 50 are respectively disposed in the positioning. The plate 3 〇 corresponds to the plate surface on which the button 40 is mounted, and the bottom edge thereof can be restrained by the positioning portion; each button 40 is mounted on the positioning plate 3 透过 through the balance foot bar 50, and each elastic The connectors are respectively mounted on the circuit film 1 and are electrically connected. The position of the point 11 is the top of each elastic coupling body 60 and is in contact with the button 4 through the through hole 31 relative to the positioning plate 30. As shown in the fifth figure, when the operator touches the button 40 downward, The button 40 has the same pressure to compress the top of the elastic coupling body to elastically deform the elastic coupling body, thereby forming the electrical contact u of the circuit thin (4), and generating a force for resetting the button 40 upward; as for the balance foot The action of the 〇 即 即 即 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程 过程The surrounding plate surface is provided with a sliding plate 33 for sliding the bottom edge of the balance foot 50, so that the upper and lower movements of the button 4 () are smoother, and the balance leg 5 is prevented from damaging the positioning plate and the member (such as the circuit film 10). ° Since the positioning plate in the overall keyboard of the present invention is formed by the plastic injection molding method, the (4) hole 31 and the positioning portion 32 are formed, thereby greatly reducing the manufacturing cost; and the circuit film 丨_臾 under the positioning (4) does not need another The opening of the perforation for the positioning part is opened, so that the processing and manufacturing cost can be greatly reduced; the 'circuit thinness is disposed between the positioning plate 3G and the support plate 20 M345289, and is not in contact with the balance leg 5〇, and can effectively avoid being balanced. In particular, the circuit board 10 is disposed between the positioning plate 30 and the support plate 20 to shield the Ai plate 3 and the support plate 2, so that a better waterproof effect can be obtained. As shown in the fourth figure, the balance leg 5〇 is a two-piece plate which is continuously assembled in the positioning portion 32 and overlapped with each other at the same time, so that the assembly method can be simplified and the manufacturing cost can be greatly reduced. In summary, the present invention provides a better and feasible keyboard improvement structure, and submits a new patent application according to law; the technical content and technical features of the present invention are disclosed above, but those skilled in the art may still be based on the present creation. The disclosure reveals various substitutions and modifications that do not depart from the spirit of the creation of the case. Therefore, the scope of protection of this creation should not be limited to those disclosed in the examples, but should include all kinds of replacements and modifications from the creations and are covered by the following patent applications.
