Abstract
The utility model provides a key. The key comprises a plastic piece, wherein a plastic film is arranged on the upper surface of the plastic piece, the position where the plastic piece corresponds to the key is a hollow space, the hollow space is formed below the plastic piece, the key comprises a metal spring piece arranged on a PCB, the metal spring piece is positioned in the hollow space, a key contact point is arranged between the top part of the metal spring piece and the plastic piece, the metal spring piece is arc-shaped, and the top part of the circular arc is contacted with the key contact point. The key provided by the utility model can prevent water and dusts from entering the PCB through the plastic thin film, and has the advantages of powerful press, convenient use, and artistic and novel appearance through improving the structures of the plastic piece and the spring.
Description
Technical field
The utility model relates to technical field of electronic products, particularly a kind of button that is used on the electronic product.
Background technology
Electronics applications is very extensive, general electronic product needs people to operate, most electronic product is to realize electronic product is controlled and operated by the button that is arranged on the PCB, the button that prior art provides contacts with pcb board and is not very tight, cause water to enter into pcb board easily, the keyboard structure that provides of prior art is unreasonable besides, causes pushing unable and not too convenient.
The utility model content
The utility model provides a kind of and pushes conveniently, and button that can waterproof.
To achieve these goals, the utility model provides following technical scheme:
A kind of button comprises sheet 103, and described sheet 103 upper surfaces are provided with plastic film 102.
Wherein, preferred, for emptying the space, and the described space of emptying is below described sheet 103 corresponding to the position of button for described sheet 103.
Wherein, preferred, described button comprises the metal spring sheet 104 that is arranged on the pcb board, and described metal spring sheet 104 is arranged in the described space of emptying, and is provided with key contacts 101 between the top of described metal spring sheet 104 and the described sheet 103.
Wherein, preferred, described metal spring sheet 104 is a circular arc, and the top of described circular arc contacts with described key contacts 101.
By above technical scheme as can be seen, the button that the utility model provides can enter pcb board by anti-sealing of plastic film and dust are set, and the structure of structure by improving sheet and spring make push strong, easy to use, good looking appearance is novel.
Description of drawings
The press-key structure schematic diagram that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of button, and as shown in Figure 1, this button comprises the sheet 103 that is used to push, and described sheet 103 upper surfaces are provided with plastic film 102.To prevent that water and dust from flowing into pcb board 105, infringement pcb board 105 from the space between the sheet 103.
In a further embodiment, for emptying the space, and the described space of emptying is below described sheet 103 corresponding to the position of button for described sheet 103.Make when pressing keys flexible and make things convenient for pressing keys.In the present embodiment, described button comprises the metal spring sheet 104 that is arranged on the pcb board 105, described metal spring sheet 104 is arranged in the described space of emptying, and be provided with key contacts 101 between the top of described metal spring sheet 104 and the described sheet 103, this keyboard contact point 101 is used for touching the metal spring sheet 104 on the pcb board 105, and metal spring sheet 104 pressurizeds are the function of switch-on keying to the plane and with pcb board 105 touchings.In other embodiments, also can be directly spring leaf is set realizes the switch-on keying function emptying the space.
Further among the embodiment, described spring leaf 104 is a circular arc, and the top of described circular arc contacts with described key contacts 101, makes when pushing more flexible.
More than a kind of button that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
