The mechanical switch can be inserted into the conductive sleeve to achieve a stable and effective electrical connection; and the flexible protective cover added between the keycap and the mechanical switch can effectively isolate the falling from the panel without affecting the feel of the mechanical switch. liquid and dust.

Description

technical field [0001] The invention relates to the technical field of input devices, in particular to an improvement technology for the installation structure and waterproof of a mechanical switch in a mechanical keyboard. Background technique [0002] The mechanical keyboard is a more complex keyboard than the membrane keyboard. The mechanical switch is used under the keycap of the mechanical keyboard; the cost of the mechanical keyboard is higher than that of the membrane keyboard, and it has the characteristics of better hand feeling, crisp sound and long mechanical life. However, mechanical switches have poor waterproof and dustproof performance, so failures cannot be avoided. [0003] The mechanical switch of the existing mechanical keyboard is directly welded on the PCB, and its defects are very obvious: once the mechanical switch is defective or damaged, it is difficult to replace the mechanical switch and the maintenance cost is high.

AI Technical Summary

Problems solved by technology

[0002]The mechanical keyboard is a more complicated keyboard than the membrane keyboard. The mechanical switch is used under the keycap of the mechanical keyboard; the cost of the mechanical keyboard is higher than that of the membrane keyboard , has the characteristics of good hand feeling, crisp sound, and long mechanical life, but the mechanical switch has poor waterproof and dustproof performance, so failures cannot be avoided

[0003] The mechanical switch of the existing mechanical keyboard is directly welded on the PCB, and its defects are very obvious: once the mechanical switch is defective or damaged, it is difficult to replace the mechanical switch and the maintenance cost is high. Generally, end users cannot replace it by themselves, even if it can be replaced. It takes a long time to waste, and there are hidden dangers of welding; in addition, this existing technology also prevents end users from choosing different types of mechanical switches for different keys of the keyboard according to their own preferences.

[0004] In order to solve the problem of difficult replacement of mechanical switches, the prior art provides a mechanical keyboard, in which a conductive sheet is welded on the PCB, and the plug pins of the mechanical switch form single-sided contact with the conductive sheet, thereby realizing electrical connection

Although this technology solves the problem that the mechanical switch is welded on the PCB and cannot be easily replaced, its defects are also obvious: the material of the pins of the mechanical switch is generally soft, prone to bending deformation, and single-sided contact is very easy to occur. In the case of poor contact, in addition, the conductive sheet is directly exposed and welded on the PCB board, which is also easy to cause looseness, and is more susceptible to poor contact due to the influence of water vapor and dust
