Description

Technical Field

[0001] The utility model relates to the field of keyboards, and particularly relates to a stabilizing ring suitable for an axis body. Background Art

[0002] At present, the bottom shell styles of mechanical axes (including magnetic axes) adopted on mechanical keyboards are usually three-pin axes and five-pin axes. When these two types of axis bodies are fixed to the PCB of the keyboard, they are fixed by first fixing the axis body to the positioning plate and then inserting it into the PCB board. That is, when the bottom pins of the axis body contact the PCB, the metal pins of the axis body will be caught by the hot-swappable socket to play a role of connection and fixation, so as to ensure that there is no error when the axis body is inserted into the PCB board. However, since the entire axis body is fixed by the hot-swappable socket and the positioning plate, this fixing method is not reliable; and due to the direct contact with the PCB board, such axis bodies will generate obvious resonance, and it is necessary to add sandwich cotton or bottom cotton between the axis body and the PCB board to reduce the resonance, which increases the production cost. Content of the Utility Model

[0003] An embodiment of the utility model provides a stabilizing ring suitable for an axis body, aiming to solve the problems that the fixing method of the existing mechanical axis body is not reliable and additional accessories are needed to reduce resonance.
