Description

A plug-in fixing structure for a pluggable ultra-thin mechanical keyboard switch Technical Field

[0001] The utility model relates to the technical field of key switches, in particular to a plug-in fixing structure of a pluggable ultra-thin mechanical keyboard switch. Background Art

[0002] A mechanical keyboard is a more complex keyboard than a membrane keyboard. Mechanical switches are used under the keycaps. Mechanical keyboards are more expensive than membrane keyboards and have the characteristics of better feel, crisp sound, and long mechanical life. However, mechanical switches have poor performance in terms of water and dust resistance, so failures are inevitable.

[0003] The mechanical switches of existing mechanical keyboards are directly soldered to the PCB board, which has obvious drawbacks: once the mechanical switch becomes defective or damaged, it is difficult and costly to replace. End users generally cannot replace it themselves. Even if they can replace it, it is time-consuming and there are soldering hazards. In addition, this existing technology also prevents end users from choosing different types of mechanical switches for different keys on the keyboard according to their own preferences.

[0004] As electronic products tend to become thinner and thinner, existing pluggable and replaceable keyboard switches are increasingly unable to meet the trend of thinning.

[0005] Utility Model Content

[0006] In response to the above-mentioned shortcomings, the purpose of the present invention is to provide a pluggable ultra-thin mechanical keyboard switch, whose internal structure is easy and quick to install, can be freely plugged in and out, and is easy to replace. It also has a low overall height, good balance, and is lighter and thinner to meet the usage needs of different people.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0008] A pluggable fixing structure for a pluggable ultra-thin mechanical keyboard switch includes a base arranged on a PCB board, a fixing plate arranged parallel to the PCB board, and at least one snap-fit ​​block respectively arranged on both sides of the base. At least one clip corresponding to the snap-fit ​​block and extending upward is respectively provided on both sides of the fixing plate. The snap-fit ​​block and the clip are engaged to fix the base to the fixing plate.

[0009] As a further improvement of the present invention, a guiding inclined surface is provided at the outermost end of the snap-fit ​​block.

[0010] As a further improvement of the present invention, the guide inclined surface is a guide inclined surface that is inclined from the outside to the inside and downward.

[0011] As a further improvement of the present invention, the upper end of the buckle is formed with a support and pressing portion extending outward.

[0012] The beneficial effects of the utility model are:

[0013] By providing a fixed plate arranged parallel to the PCB board and at least one snap-fit ​​block respectively arranged on both sides of the base, at least one clip is provided on each side of the fixed plate, corresponding to the snap-fit ​​block and extending upward. The snap-fit ​​block and the clip are engaged to fix the base to the fixed plate. When disassembly is required, the clip can be opened by simply using a sharp object to separate the snap-fit ​​block from the clip, and the pluggable ultra-thin mechanical keyboard switch can be pulled out for replacement and other operations. The mutual cooperation between the snap-fit ​​block and the clip makes the pluggable ultra-thin mechanical keyboard switch freely pluggable and easy to replace on the PCB board. The plug-in installation method is convenient and quick, improving the user experience. The overall height of the fixed plate and base is relatively low, well-balanced, and more lightweight, which can effectively meet the needs of different users.

[0014] The above is an overview of the technical solution of the utility model. The utility model will be further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] Please refer to Figures 1 to 3. An embodiment of the present invention provides a pluggable and fixed structure for an ultra-thin mechanical keyboard switch, comprising a base 1 arranged on a PCB board 3, characterized in that it comprises a fixing plate 2 arranged parallel to the PCB board 3, and at least one snap-fit ​​block 11 respectively arranged on both sides of the base 1, at least one clip 21 corresponding to the snap-fit ​​block 11 and extending upward is respectively provided on both sides of the fixing plate 2, the snap-fit ​​block 11 and the clip 21 being snap-fitted to fix the base 1 on the fixing plate 2, and other components of the pluggable and ultra-thin mechanical keyboard switch are arranged on the base. When disassembly is required, the clip 21 only needs to be propped open with a sharp object to separate the snap-fit ​​block 11 from the clip 21, and the pluggable and ultra-thin mechanical keyboard switch can be pulled out to achieve operations such as replacement. The mutual cooperation between the snap-fit ​​block 11 and the buckle 21 enables the pluggable ultra-thin mechanical keyboard switch to be freely pluggable on the PCB board 3, which is easy to replace, and the plug-in installation method is convenient and quick, which improves the user experience. The overall height of the matching structure of the fixing plate 2 and the base 1 is low, well-balanced, and thinner, which can effectively meet the usage needs of different people.

[0026] Regarding the positioning of the fixing plate 2, the fixing plate 2 can be positioned below the PCB board 3, with the base 1 and fixing plate 2 securing the PCB board 3, thereby electrically connecting the other components of the pluggable ultra-thin mechanical keyboard switch on the base 1 to the PCB board 3. Alternatively, the fixing plate 2 can be positioned above the PCB board 3, with the fixing plate 2 secured to the PCB board 3 and the base 1 inserted into the fixing plate 2, thereby electrically connecting the other components of the pluggable ultra-thin mechanical keyboard switch on the base 1 to the PCB board 3. Both approaches can be selected and adjusted based on actual circumstances and are not specifically limited in this embodiment.

[0027] In order to better install the base 1 on the fixed plate 2, as shown in Figures 1 to 3, a guiding inclined surface 111 is provided at the outermost end of the snap-fit ​​block 11. When the user or manufacturer needs to install the base 1 on the fixed plate 2, the guiding inclined surface 111 first contacts the buckle 21. Under the guiding action of the guiding inclined surface 111, the snap-fit ​​block 11 moves toward the inner side of the buckle 21, making it easier to enter the buckle 21 from the inner side of the buckle 21, completing the installation of the pluggable ultra-thin mechanical keyboard switch, facilitating the coordination between the various components, improving the speed and accuracy of installing the base 1 on the fixed plate 2, and further improving the efficiency of installation.

[0028] As for the specific structural setting of the guide inclined surface 111, as shown in Figures 1 to 3, the guide inclined surface 111 is a guide inclined surface 111 that is inclined from the outside to the inside and downward. The structure of inclining from the outside to the inside and downward makes it easier for the snap-fit ​​block 11 to be installed in the buckle 21, and its longest outer end is at a higher position, which effectively prevents the base 1 from detaching from the fixing plate 2 during use, ensures a stable connection between the base 1 and the fixing plate 2, and improves the reliability of this structure.

[0029] As for the specific method of pulling the base 1 out of the fixing plate 2, as shown in Figures 2 to 3, a support groove 12 is provided in the middle of the snap-fit ​​block 11. The user inserts a sharp-headed object into the support groove 12 and applies outward force to the groove to push the buckle 21 outward, thereby disengaging the snap-fit ​​block 11 from the buckle 21. After the disassembly of the base 1 is completed, the pluggable ultra-thin mechanical keyboard switch can be taken out for replacement or repair, etc. The entire operation is convenient and fast, and easy to replace.

[0030] In order to make it easier for objects with sharp heads to be stretched into the stretching groove 12, as shown in Figures 1 to 3, the upper end of the buckle 21 is formed with a stretching and pressing portion 211 extending outward. When the object with a sharp head is inserted into the stretching groove 12 to stretch the stretching groove 12, the action arm of the object with a sharp head will inevitably tilt outward. The outward extending structure of the stretching and pressing portion 211 provides space for the object with a sharp head to tilt outward, so that the action arm of the object with a sharp head can better act on the buckle 21, further improving the speed and efficiency of pulling out the base 1 from the fixing plate 2.

[0031] It should be noted that the pluggable, ultra-thin mechanical keyboard switch fixing structure disclosed in this utility model is an improvement to a specific structure, and the specific control method is not the innovation of this utility model. The PCB board and other components involved in this utility model can be common standard parts or components known to those skilled in the art. Their structure, principles, and control methods are all known to those skilled in the art through technical manuals or routine experimental methods.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the scope of protection of the present invention.
