Keyboard adopting plastic-injection baseboard and production method of keyboard

Abstract

The invention relates to a keyboard adopting plastic-injection baseboard and a production method of the keyboard, and the keyboard is used for laps or desktop computers. The keyboard comprises a plurality of button caps arranged at interval, scissor legs, a plurality of elastic colloidal silica, a plurality of lower pin fixing seats, a keyboard baseboard and a printed circuit film covered on the surface of the keyboard baseboard, wherein the bottom surface of the button cap is provided with upper pin fixing seats; after the components are assembled, the upper pins of the scissor legs are spliced and fixed on the upper pin fixing seats; the lower pins of the scissor legs are spliced and fixed on the lower pin fixing seats; the top of the elastic colloidal silica is propped against the bottom surface of the button cap; the bottom of the elastic colloidal silica is positioned on the button switch of the printed circuit film; and each lower pin fixing seat and the keyboard baseboard are the same plastic piece injected and shaped once by a plastic material. According to the invention, the production process is simplified, production cost is lowered, assembling accuracy and automated assembling efficiency are improved, product quality is guaranteed, and the invention is suitable for automated production.

Description

A keyboard using a plastic injection molding bottom plate and its production method technical field The invention relates to the technical field of computer keyboards, in particular to a keyboard using a plastic injection molding bottom plate for a notebook computer or a desktop computer and a production method thereof. Background technique With the development of the information industry, computers have been increasingly widely used. No matter be the application of notebook computer or desktop computer all be unable to do without computer keyboard, existing notebook keyboard and some desktop computers such as the light and thin type keyboard that Apple computer adopts, its structure mostly adopts the keycap that several slices are distributed at intervals, and keycap One-to-one correspondence of several scissor feet and several elastic silicon gels, several lower pin holders corresponding to the lower pins of several scissor feet, keyboard bottom plate and printed circuit...

No matter be the application of notebook computer or desktop computer all be unable to do without computer keyboard, existing notebook keyboard and some desktop computers such as the light and thin type keyboard that Apple computer adopts, its structure mostly adopts the keycap that several slices are distributed at intervals, and keycap One-to-one correspondence of several scissor feet and several elastic silicon gels, several lower pin holders corresponding to the lower pins of several scissor feet, keyboard bottom plate and printed circuit film covering the surface of the keyboard bottom plate are assembled. As shown in Figure 1, holes b are directly punched on the aluminum plate a and a number of fixing hooks c are formed to form the lower pin fixing seat. The accuracy of the hook is poor, it is difficult to realize automatic production in assembly, the cost of manual operation is high, and automatic assembly cannot be realized
