Description

Technical Field

[0001] The utility model relates to a connecting terminal, in particular to a keyboard shaft base terminal supporting hot plugging. Background Art

[0002] Due to the rise of the PC e-sports market, the demand for mechanical keyboards has grown exponentially. Although a mechanical keyboard has dozens to hundreds of keys, users tend to focus on a few of them when using them, causing these keys to be damaged earlier than other keys. At this time, if the entire keyboard cannot be used because of one key, the cost of using the mechanical keyboard will be very high. Based on this, hot-swappable keyboard axes have been developed on the market, and consumers can replace damaged keyboard axes by themselves.

[0003] However, due to the wide variety of keyboard axes on the market, users may encounter situations where the keyboard axis does not match the terminal after purchasing the keys; or even if the keyboard axis can be inserted, the unstable contact may cause a disconnection.

[0004] At present, some keyboard axis base terminals are equipped with multiple contact points to improve the contact stability with the keyboard axis, such as the terminal structure disclosed in Chinese utility models CN218038900U and CN218182099U. However, the multiple contact points of the above terminals all apply force through a bending area at the top, and the contact force is limited, resulting in the inability to further improve the contact stability. In addition, the above terminals are still incompatible with the keyboard axis. Utility Model Content

[0005] The technical solution of the present utility model is aimed at the above situation. In order to solve the above problem, a keyboard axis base terminal supporting hot plugging is provided, wherein the terminal has a welding section, a positioning section and a clamping section, and the welding section, the positioning section and the clamping section are connected in sequence along the front-to-back direction; the clamping section has at least two first spring pieces and at least two second spring pieces, the first spring piece has a first bending portion and a first contact portion, the first bending portion is connected to the first contact portion, the two first contact portions are opposite to each other along the left-right direction to form a first clamping space, the second spring piece has a second bending portion and a second contact portion, the second bending portion is connected to the second contact portion, the two second contact portions are opposite to each other along the left-to-right direction to form a second clamping space, and the first clamping space and the second clamping space are opposite to each other along the up-down direction.

[0006] Furthermore, the first bent portion is connected to the first contact portion along the up-down direction, and the second bent portion is connected to the second contact portion along the front-back direction.

[0007] Furthermore, the first clamping space is located directly above the second clamping space.

[0008] Furthermore, the first bent portion is located above the first contact portion, and the second bent portion is located behind the second contact portion.

[0009] Furthermore, the second elastic sheet also has an upper extension portion and a lower extension portion, the upper extension portion and the lower extension portion are respectively connected to the upper end and the lower end of the second contact portion, and the upper extension portion and the lower extension portion are both bent relative to the second contact portion.

[0010] Furthermore, the positioning section has at least two buckles and a limit buckle that are opposite to each other in the left-right direction, the two buckles protrude outward from the left wall and the right wall of the positioning section respectively, and the limit buckle protrudes inward from the lower wall of the positioning section.

[0011] After adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. Since the clamping section of the terminal is provided with at least two oppositely arranged first spring sheets and at least two oppositely arranged second spring sheets, and the first spring sheets and the second spring sheets are independently arranged and have independent bending parts, sufficient clamping force can be applied to the keyboard axis, thereby improving contact stability.

[0013] 2. Since the first spring sheet and the second spring sheet are independently arranged, the sizes of the first clamping space and the second clamping space can be freely adjusted. In this way, whether it is thicker or thinner keyboard axis, it can be compatible with the terminal, thereby improving the compatibility of the terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described below by way of embodiments:

[0018] The utility model provides a keyboard shaft base terminal supporting hot plugging, combined with Figures 1-2As shown, the terminal has a welding section 1, a positioning section 2 and a clamping section 3, and the welding section 1, the positioning section 2 and the clamping section 3 are connected in sequence along the front-to-back direction; the clamping section 3 has at least two first spring pieces 31 and at least two second spring pieces 32, the first spring piece 31 has a first bending portion 311 and a first contact portion 312, the first bending portion 311 is connected to the first contact portion 312, the two first contact portions 312 are opposite to each other along the left-right direction to form a first clamping space, the second spring piece 32 has a second bending portion 321 and a second contact portion 322, the second bending portion 321 is connected to the second contact portion 322, the two second contact portions 322 are opposite to each other along the left-right direction to form a second clamping space, and the first clamping space and the second clamping space are opposite to each other along the up-down direction.

[0019] When installing the terminal, the terminal is fixed in the groove of the keyboard shaft base, the positioning section 2 is fixed to the keyboard shaft base, and the welding section 1 is used to weld with the circuit, such as Figure 3 As shown, the clamping section 3 is used to clamp the keyboard shaft 100 of the key. When the keyboard shaft 100 is inserted, the first bent portion 311 applies a force toward the first clamping space to the first contact portion 312, and the second bent portion 321 applies a force toward the second clamping space to the second contact portion 322, thereby clamping the keyboard shaft 100.

[0020] In the utility model, since the clamping section 3 of the terminal is provided with at least two oppositely arranged first spring pieces 31 and at least two oppositely arranged second spring pieces 32, and the first spring pieces 31 and the second spring pieces 32 are independently arranged and have independent bending parts, sufficient clamping force can be applied to the keyboard axis 100, thereby improving the contact stability.

[0021] In addition, since the first spring piece 31 and the second spring piece 32 are independently arranged, the sizes of the first clamping space and the second clamping space can be freely adjusted, such as increasing the first clamping space and reducing the second clamping space. In this way, whether it is a thicker or thinner keyboard axis 100, it can be compatible with the terminal, thereby improving the compatibility of the terminal.

[0022] Specifically, please continue to combine Figures 1-2 As shown, the first bending portion 311 is connected to the first contact portion 312 in the up-down direction, and the second bending portion 321 is connected to the second contact portion 322 in the front-back direction. The above structure makes the first spring piece 31 arranged vertically, and the second spring piece 32 is arranged horizontally, and the two terminals are arranged perpendicular to each other, which fully utilizes the space in two directions of the groove of the keyboard axis base. Compared with the structure that concentrates on utilizing the space in a single direction of the groove, the above structure can be used to set a larger space for the spring piece, and the larger the size of the spring piece, the greater the clamping force.

[0023] More specifically, the first clamping space is located directly above the second clamping space. Generally, the horizontal space at the lower end of the groove of the keyboard axis base is larger, so arranging the second spring piece 32 below the first spring piece 31 can provide more space for setting the size of the second spring piece 32.

[0024] More specifically, the first bent portion 311 is located above the first contact portion 312, and the second bent portion 321 is located behind the second contact portion 322. The above arrangement can fully utilize the external space of the terminal.

[0025] For details, please continue to refer to Figure 3 As shown, the second elastic piece 32 further has an upper extension portion 323 and a lower extension portion 324, which are respectively connected to the upper end and the lower end of the second contact portion 322, and the upper extension portion 323 and the lower extension portion 324 are both bent relative to the second contact portion 322. The upper extension portion 323 and the lower extension portion 324 can increase the contact area with the keyboard shaft 100 when the second contact portion 322 is deformed, thereby improving the contact stability.

[0026] For details, please continue to refer to Figure 2 As shown, the positioning section 2 has at least two buckles 21 and a limit buckle 22 facing each other in the left-right direction, the two buckles 21 protrude outward from the left wall and the right wall of the positioning section 2 respectively, and the limit buckle 22 protrudes inward from the lower wall of the positioning section 2. The buckle 21 is used to engage with the locking position of the keyboard shaft base, and the positioning hole 22 is used to engage with the limit pin of the keyboard shaft base, so as to form a fixation.
