Problems solved by technology
Static electricity will be attracted by the electronic components closest to the keycap, and damage the electronic components and components electrically connected to them, such as circuit boards, etc., thus causing damage to the components
In addition, after the keyboard is completed, static electricity is easily transmitted to the membrane switch layer through the light-emitting element of the keyboard during electrostatic testing, thus causing damage to the membrane switch layer and the components electrically connected to it

The present invention relates to a keyboard structure which comprises a conductive bottom plate, key caps, a film circuit layer, light-emitting elements and a conductive cover. The conductive bottom plate is grounded. The key caps are arranged on the conductive bottom plate and can move up and down relative to the conductive bottom plate. The film circuit layer is arranged between the conductive bottom plate and key caps. The light-emitting elements are arranged on the film circuit layer and are used for emitting light. The conductive cover is arranged on the film circuit layer and covers the light-emitting elements. The conductive cover is provided with a transparent region, and the light can go through the transparent region to reach the key caps. The conductive cover is adjacent to the static electricity leading part of the conductive bottom plate. A discharge path is formed by the conductive cover and the static electricity leading part, static electricity can be conducted and grounded through the discharge path, thus the damage of the light-emitting elements or / and the light emitting elements which are electrically connected to the light-emitting elements such as a circuit board is avoided.
Description
technical field [0001] The present invention relates to a keyboard structure, and in particular to a keyboard structure with a discharge path. Background technique [0002] The keyboard is easy to receive static electricity from fingers during use. Static electricity will be attracted by the electronic components closest to the keycap, and damage the electronic components and components electrically connected to them, such as circuit boards, etc., thus causing damage to the components. In addition, after the keyboard is completed, static electricity is easily transmitted to the membrane switch layer through the light-emitting element of the keyboard during electrostatic testing, thus causing damage to the membrane switch layer and components electrically connected thereto. Therefore, it is urgent to propose a solution that can discharge static electricity. Contents of the invention [0003] Therefore, the present invention proposes a keyboard structure, which provides a ...
