Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a keyboard with a film circuit board positioning structure. Background Art

[0002] Because the scissor feet were installed directly on the film circuit board from above during keyboard assembly, the film circuit board was laid directly on the bottom plate, and positioning columns were set on the bottom plate to limit the movement of the film circuit board in the X and Y directions. However, with the upgrade of the automated assembly method of the scissor feet, the more efficient assembly method is to place the scissor feet in the jig, and after the bottom plate and the film circuit board are assembled, turn the film circuit board over and place it face down on the jig where the scissor feet are placed, and then press them in together. However, under this production method, the film circuit boards at both ends will fall off the bottom plate during the flipping process, affecting the assembly efficiency and yield rate. Utility Model Content

[0003] Purpose of the utility model: The utility model aims to provide a keyboard and a keyboard with a thin film circuit board positioning structure that can prevent the thin film circuit board from falling off during the assembly process.

[0004] Technical solution: The utility model provides a keyboard with a thin film circuit board positioning structure, comprising a base plate and a thin film circuit board. The base plate is provided with a positioning structure for the thin film circuit board. The positioning structure comprises a main body. The top of the main body is provided with a bending portion for supporting the upper surface of the thin film circuit board. The thin film circuit board is provided with a through hole matching the positioning structure.

[0005] Furthermore, the bending portion is bent to one side, and the bending surface abuts against the upper surface of the film circuit board.

[0006] Furthermore, the bending portion is bent toward two sides, and the bending surface abuts against the upper surface of the film circuit board.

[0007] Furthermore, the positioning structure is an iron plate hook fixedly connected to the bottom plate.

[0008] Furthermore, the positioning structure body and the bending portion are integrally formed

[0009] Furthermore, the positioning structure and the base plate are embedded in the molding.

[0010] Furthermore, there are a plurality of positioning structures.

[0011] Furthermore, it also includes a key cap, a scissor foot, and an elastic element, and the base plate is also provided with a fixing hook for the scissor foot.

[0012] The utility model provides a keyboard, the keys of which adopt the keyboard structure with the film circuit board positioning structure as described above.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model limits the Z-direction movement of the thin film circuit board through the setting of the thin film circuit board positioning structure, so that the thin film circuit board is always in contact with the base plate during the automated assembly flipping process, thereby improving the keyboard assembly efficiency and yield rate.
