Embodiment Construction

[0015] like Figure 1-Figure 4 As shown, the present invention is an improvement to the existing keyboard, and its main purpose is to improve the radiation protection function of the keyboard. The improvement of the present invention mainly includes the following points.

[0016] A copper plate with a thickness of 0.2mm is installed above the circuit board, and an iron plate with a thickness of 0.4mm is installed under the circuit board. The copper plate has good conductivity. At high frequency, the good magnetic permeability of copper foil makes the equipment have good electromagnetic shielding performance, and the iron plate has the characteristics of low magnetic resistance. At low frequency, the magnetic permeability of the iron plate is not reduced, and the characteristics of low magnetic resistance make the equipment Good electromagnetic shielding performance.

[0017] There is a hot-melt column with a diameter of 1mm between any two keys on the middle plate. The thickn...

Abstract

The invention belongs to the field of design computers and in particular to a keyboard. The low radiation keyboard includes a mechanical part and a circuit board which are intended for realizing restoration of a keycap after clicking the keycap. The mechanical part includes silica gel particles, a first scissors kick, a keycap, a second scissors kick and a middle plate. A copper plate having a thickness of 0.2mm is disposed between the circuit board and the mechanical part. An iron plate having a thickness of 0.4mm is disposed below the circuit board. The copper plate is provided with a circle hole having a diameter of 5.5mm-6.5mm at a position corresponding to keys. According to the invention, the keyboard herein has the following beneficial advantages: the keyboard herein has the characteristics of low radiation, water resistance and lightness; the keyboard can be applied to different devices in the field of national defense, army, petroleum and petrochemical industries, and special environments such as exploration.

Description

technical field [0001] The invention relates to the field of computers, in particular to a keyboard. Background technique [0002] In recent years, with the continuous development of science and technology, computers have been integrated into all aspects and fields of today's society. The application and development of computer technology are impacting and changing the way people think and work. With the development of scientific and technological productivity, the requirements for computer technology and products in various fields are constantly increasing, especially specialized products applied in special environments such as national defense, petroleum, petrochemical, and electric power exploration will inevitably become the foundation of computer technology and product development. a trend. [0003] As an independent input device of the computer, the keyboard is changed to the main structure mostly made of ABC plastic or PC material, without electromagnetic shielding t...
