Description

Technical Field

[0001] The invention relates to the technical field of key switches, and in particular to a conducting member 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. The cost of a mechanical keyboard is relatively higher than that of a membrane keyboard. It has the characteristics of better feel, crisp sound, and long mechanical life. However, mechanical switches have poor performance in terms of waterproofing and dustproofing, so failures are inevitable.

[0003] The mechanical switches of existing mechanical keyboards are directly soldered on the PCB board, which has obvious defects: once the mechanical switch is defective or damaged, it is difficult to replace the mechanical switch and the maintenance cost is high. End users generally cannot replace it by themselves. Even if they can replace it, it wastes a lot of time and there are hidden dangers of soldering. 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 addition, the conduction structure of the existing mechanical switch needs to be fixed on a structure such as a housing or a conductor core. The structure is relatively delicate and requires high precision for fixation. The technology is difficult and consumes a lot of manpower and material resources, which is not suitable for current rapid production needs.

[0005] As electronic products tend to be thinner and thinner, existing pluggable and replaceable keyboard switches are increasingly unable to keep up with the trend of thinning. Summary of the invention

[0006] In view of the above-mentioned deficiencies, the object of the present invention is to provide a pluggable ultra-thin mechanical keyboard switch conductive component, which has good contact stability, convenient and quick internal structure installation, easy replacement, accurate conduction and disconnection action, good elastic recovery force, and a relatively 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 conductive part of a pluggable ultra-thin mechanical keyboard switch includes a fixing seat and a conductive part. The conductive part is a conductive elastomer, and a fixing part is arranged in the middle of the conductive elastomer; a first elastic arm and a second elastic arm extend to both sides respectively from the fixing part, a conductive driving part is arranged at the end of the first elastic arm, and a conductive fixing part is arranged at the second elastic arm.

[0009] As a further improvement of the present invention, the conductive elastomer is a torsion spring, which includes a fixed portion mounted on the fixed seat, a first elastic arm extending outward from the fixed portion, a conductive driving portion integrally formed at the outermost end of the first elastic arm and bent to extend outward, a second elastic arm extending outward from the fixed portion toward the other end, and a conductive fixed portion integrally formed at the outermost end of the second elastic arm and bent to extend inward.

[0010] As a further improvement of the present invention, a conductive contact portion bent downward is formed on the first elastic arm.

[0011] As a further improvement of the present invention, the fixing seat is provided with a mounting portion for installing the conductive part, and the mounting portion includes a first transverse mounting groove for the conductive driving part to be placed, a first longitudinal mounting groove connected to one side of the first transverse mounting groove and for the first elastic arm to be placed in a movable manner, a fixing portion mounting groove connected to the tail end of the first longitudinal mounting groove and for the fixing portion to be placed in, a second longitudinal mounting groove connected to the other end of the fixing portion mounting groove and for the second elastic arm to be placed in a movable manner, and a second transverse mounting groove connected to the tail end of the second longitudinal mounting groove and for the conductive fixing portion to be placed in.

[0012] As a further improvement of the present invention, the PCB board is provided with an electrical connection static contact directly opposite to the conductive fixing portion, and an electrical connection moving contact directly opposite to the conductive contact portion, and the conductive fixing portion is fixedly pressed against the electrical connection static contact.

[0013] The beneficial effects of the present invention are as follows: by setting the conducting part as a conductive elastomer and hooking the conducting part on the conducting hook, the installation of the conducting part is easier. Only the torsion spring needs to be placed on the driving rod and the fixing seat to realize the conduction and disconnection of the mechanical key. No welding and fixing are required. The installation technology requirements are low, the installation is convenient and quick, and manpower and material resources are saved. In addition, the conduction and disconnection actions are accurate, and the elastic recovery force is good, thereby improving the practicality of the mechanical keyboard switch.

[0014] The above is an overview of the technical solution of the invention. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 to 5 The embodiment of the present invention provides a conducting member 3 of a pluggable ultra-thin mechanical keyboard switch, comprising a fixing seat 1 and a conducting member 3. The conducting member 3 is a conductive elastic body, and a fixing portion 31 is provided in the middle of the conductive elastic body; a first elastic arm 32 and a second elastic arm 34 extend from the fixing portion 31 to both sides, respectively, and a conducting driving portion 33 is provided at the end of the first elastic arm 32, and a conducting fixing portion 35 is provided at the second elastic arm 34. By setting the conducting member 3 as a conductive elastic body, the conducting fixing portion 35 thereof is stably electrically connected and conducted with the PCB board 6. When the user presses the pluggable ultra-thin mechanical keyboard switch, the driving rod 4 in the pluggable ultra-thin mechanical keyboard switch moves downward, and the conducting driving portion 33, under the action of its own elastic restoring force, takes the fixing portion 31 as the axis, and the conducting driving portion 33 rotates downward to the middle of the first elastic arm 32 to be electrically connected and conducted with the PCB board 6, completing a signal input. When the user releases the pluggable ultra-thin mechanical keyboard switch, the balance frame assembly 2 in the pluggable ultra-thin mechanical keyboard switch drives the driving rod 4 in the pluggable ultra-thin mechanical keyboard switch to move upward, and the driving rod 4 pulls up the conduction driving part 33, so that the conduction member 3 undergoes elastic deformation, and the first elastic arm 32 connected to the conduction driving part 33 is driven to separate from the PCB board 6, thereby realizing the disconnection of the electrical signal. It has good contact stability, convenient and quick installation of the internal structure, accurate conduction and disconnection actions, and good elastic recovery force, thereby improving the accuracy and installation efficiency of the mechanical keyboard switch.

[0026] Regarding the specific structural arrangement of the conductive member 3, as shown in FIG. Figure 1 to Figure 2 ,as well as Figure 5 As shown, the conductive elastic body is a torsion spring, which includes a fixing portion 31 mounted on the fixing seat 1, a first elastic arm 32 extending outward from the fixing portion 31, a conductive driving portion 33 integrally formed at the outermost end of the first elastic arm 32 and bent 90 degrees to extend outward, a second elastic arm 34 extending outward from the fixing portion 31 toward the other end, and a conductive fixing portion 35 integrally formed at the outermost side of the second elastic arm 34 and bent inward to extend. By setting the conductive member 3 as a torsion spring and the overall integrally formed structure, the conductive member 3 is not easy to break, which increases its service life, and does not need to be molded separately, saving costs, and further improving the practicality of the conductive member. By setting a conductive driving portion 33 extending outward in a bent manner at the outermost end of the first elastic arm 32, the driving rod 4 can better pull up the conductive driving portion 33. By arranging a conductive fixing portion 35 that is bent and extends inwardly at the outermost side of the second elastic arm 34 , the contact surface is large, so that the conductive member 3 can be better fixedly electrically connected to the PCB board 6 .

[0027] Preferably, the angle at which the conducting fixing portion 35 bends inwardly extends is 90 degrees, and its contact surface is large, so that the conducting member 3 is more fixed and electrically connected with the PCB board 6 .

[0028] Preferably, the angle at which the conducting driving portion 33 bends outwardly extends is 90 degrees, so that the driving rod 4 can better pull the conducting driving portion 33 up.

[0029] For other structural settings of the pluggable ultra-thin mechanical keyboard switch, such as Figure 1 and Figure 2 As shown, the pluggable ultra-thin mechanical keyboard switch also includes a balance frame assembly 2 rotatably arranged on the fixed seat 1, and the balance frame assembly 2 includes a balance frame A21 rotatably connected to the fixed seat 1, a balance frame B22 rotatably connected to the fixed seat 1 and the balance frame A21, and a tension spring 23 connected between the balance frame A21 and the balance frame B22. The balance frame assembly 2 provides balance and stability for the pressing of the mechanical keyboard switch, and the tension spring 23 provides elastic restoring force for pressing and resetting. The balance frame assembly 2, the driving rod 4 and the fixed seat 1 cooperate, and the driving rod 4 is linked to combine the pressing balance function and the pressing conduction function, thereby reducing the overall height, improving the balance, and having good contact stability, which meets the use needs of different people. In specific use, a key cap is installed on the balance frame A21 and the balance frame B22. The specific structure of the balance frame A21 and the balance frame B22, and the installation method of the keycaps are not the innovation points of the present invention. As for the specific structure, the patent number is 202121092814.4, and the patent name is "A photoelectric key switch with increased pressing feel", which will not be repeated here.

[0030] For the connection between the drive rod 4 and the balance frame assembly 2 , such as Figure 1 and Figure 2 As shown, a pressing linkage block 41 is provided on one end of the driving rod 4, and a pressing protrusion 221 is provided on the balancing frame assembly 2 and is located above the pressing linkage block 41. When the balancing frame assembly 2 is pressed and moved downward, the pressing protrusion 221 directly acts on the pressing linkage block 41, thereby driving the driving rod 4 to move downward, and the driving rod 4 moves downward while driving the other end of the conductive member 3 to move downward, so that the conductive member 3 is connected to the PCB board 6, and the input is completed. The whole structure is simple and clear, and the stability is high.

[0031] For the connection mode of the driving rod 4 and the conductor 3, such as Figure 2 and Figure 3As shown, the lower part of one end of the driving rod 4 close to the pressing linkage block 41 is formed with a conducting hook 42 in the shape of "∟". The conducting driving part 33 in the conducting member 3 is hooked on the conducting hook 42. The "∟"-shaped structural setting makes the conducting member 3 more stable when hooked, and is convenient for the manufacturer to install the conducting member 3 on the conducting hook 42 from the side, thereby reducing technical difficulty, facilitating and quickly installing, saving manpower and material resources, and achieving accurate conducting and disconnecting actions, thereby improving the accuracy and installation efficiency of the pluggable ultra-thin mechanical keyboard switch.

[0032] The specific method of electrically connecting the first elastic arm 32 and the PCB board 6 is as follows: Figure 2 and Figure 5 As shown, a conductive contact portion 36 is formed on the first elastic arm 32 and bent downward. When the balance frame assembly 2 is pressed downward, the pressing protrusion 221 acts on the driving rod 4, and the driving rod 4 acts on the conductive driving portion 33 of the torsion spring through the conductive hook 42, thereby driving the conductive contact portion 36 until it contacts the PCB board 6 to achieve electrical connection and complete a signal input. The conduction and disconnection actions are accurate, which improves the accuracy and installation efficiency of the pluggable ultra-thin mechanical keyboard switch.

[0033] The specific method of installing the conductive member 3 on the fixing seat 1 is as follows: Figure 2 and Figure 4 As shown, the fixing seat 1 is provided with a mounting portion 11 for mounting the conductive member 3, and the mounting portion 11 includes a first transverse mounting groove 111 for the conductive driving portion 33 to be placed, a first longitudinal mounting groove 112 connected to one side of the first transverse mounting groove 111 and for the first elastic arm 32 to be placed and moved, a fixing portion mounting groove 113 connected to the tail end of the first longitudinal mounting groove 112 and for the fixing portion 31 to be placed, a second longitudinal mounting groove 114 connected to the other end of the fixing portion mounting groove 113 and for the second elastic arm 34 to be placed and moved, and a second transverse mounting groove 115 connected to the tail end of the second longitudinal mounting groove 114 and for the conductive fixing portion 35 to be placed. The conductive fixing portion 35 is pressed against the PCB board 6 through the lower end of the second transverse mounting groove 115. Through the one-to-one corresponding installation groove arrangement, the conductive member 3 is stably installed on the fixing seat 1, and has sufficient space to move up and down to realize different operations of conduction and disconnection, and accurately limits the moving stroke of each part of the conductive member 3, effectively preventing the conductive member 3 from shifting during the activity and causing the problem of not being able to operate normally. The conduction and disconnection actions are accurate, which improves the input efficiency of the mechanical keyboard switch.

[0034] Regarding the specific method of conducting the conductive member 3 with the PCB, as shown in FIG. Figure 2As shown, the PCB board 6 is provided with an electrical connection static contact 61 facing the conductive fixing portion 35, and an electrical connection moving contact 62 facing the conductive contact portion 36. The conductive fixing portion 35 is fixedly pressed against the electrical connection static contact 61, thereby realizing the conduction of one end of the conductive member 3. When the conductive contact portion 36 is pressed by the user, it moves downward due to its own elastic restoring force, so that the conductive contact portion 36 contacts the electrical connection moving contact 62 to realize electrical connection and conduction. When the two ends are conductive, a complete circuit is formed between the conductive member 3 and the PCB board 6, completing a signal input.

[0035] Regarding the specific relationship between the driving rod 4 and the fixing base 1 when the driving rod 4 moves, as shown in FIG. Figures 1 to 3 As shown, the driving rod 4 is provided with an embedding groove 43 located just above the mounting portion 11. When the driving rod 4 moves downward, the mounting portion 11 is embedded in the embedding groove 43, so that the driving rod 4 can move on the fixing seat 1, thereby realizing the elastic reset of the conductive driving portion 33 and the conductive hook 42, so that the switch of the mechanical keyboard is turned on. When the driving rod 4 moves upward, the mounting portion 11 leaves the embedding groove 43, and the conductive hook 42 of the driving rod 4 pulls up the conductive driving portion 33 and the first torsion arm 32, thereby realizing the disconnection of the switch of the mechanical keyboard. The whole operation is smooth, and the mounting portion 11 corresponds to the structure that moves on the embedding groove 43, so that the movable stroke of the embedding groove 43 is limited, thereby improving the activity accuracy of the driving rod 4 and improving the input efficiency.

[0036] In order to prevent the conductive member 3 from being separated from the upper part of the fixing seat 1 during the pulling process, Figures 1 to 3 As shown, the mechanical keyboard switch also includes a dust cover 5 covering the embedding groove 43, and the upper part of the conductive member 3 is blocked by the dust cover 5, so that the conductive member 3 is better restricted by the mounting portion 11, thereby improving the accuracy of the movement and effectively preventing the conductive member 3 from detaching from the upper part of the fixing seat 1 when being pulled.

[0037] The driving rod 4 touches and presses down to make the conductive contact part 36 just conduct the PCB board 6, or the driving rod 4 applies force to further press the conductive contact part 36 down and then conduct the PCB board 6, which are all within the protection scope of the present invention.

[0038] It should be noted that the pluggable ultra-thin mechanical keyboard switch conductive member disclosed in the present invention is an improvement on the specific structure, and the specific control method is not the innovation of the present invention. The key caps, PCB boards and other components involved in the present invention can be universal standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0039] The above description is only 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-mentioned embodiments of the present invention are within the protection scope of the present invention.
