Description

Technical Field

[0001] This utility model belongs to the field of conductive connector technology, and specifically relates to a combined terminal structure for hot-swappable keyboards. Background Technology

[0002] With the rise of the PC and e-sports markets, the demand for mechanical keyboards has increased exponentially, leading to a surge in demand for hot-swappable switch bases. Since a hot-swappable switch is a signal switch that uses two terminals to achieve on / off switching, and traditional hot-swappable switches have two staggered signal pins, the assembly of the switch base and the two terminals must be done one at a time. This double-assembly process results in dimensional instability due to accumulated assembly differences, low assembly efficiency, and separate surface treatment for each component, significantly increasing product costs. Therefore, there is an urgent need to develop a modular terminal structure to improve assembly efficiency and quality while reducing production costs. Utility Model Content

[0003] To address the above problems, this utility model provides a combined terminal structure for hot-swappable keyboards.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A combined terminal structure for hot-swappable keyboards includes a substrate and one or more terminal groups. Each terminal group includes two terminals, which are disposed in a cutout area on the substrate. The two terminals are arranged opposite to each other and connected to the substrate. The two terminals are staggered to correspond to two staggered signal pins of the hot-swappable shaft.

[0006] Furthermore, the material plate includes one or more long strips arranged in parallel, and each set of terminal groups has a bridge strip connecting the two parallel strips on both sides, and the two strips and the two bridge strips surround each other to form a hollow area.

[0007] Furthermore, the terminal, bridge strip, and material strip are an integrated structure, processed from a single flat plate.

[0008] Furthermore, the strip is provided with a row of connecting holes.

[0009] Furthermore, the material strips are in pairs or more, with two adjacent material strips forming an integral structure and two adjacent rows of connecting holes arranged alternately; two adjacent sets of terminal groups on the left and right are separated by a bridge strip.

[0010] Furthermore, a row of positioning holes is provided between two adjacent rows of connecting holes, and the positioning holes are arranged alternately with the connecting holes.

[0011] Furthermore, the terminal is divided into a connecting part, a positioning part, and a plug-in part along its length. The connecting part is used to connect to the material plate and can be soldered to the keyboard circuit. The positioning part is used to connect to the keyboard switch base. The plug-in part is used to clamp the keyboard switch. The bottoms of the connecting part, positioning part, and plug-in part are flush. The height of the positioning part is lower than the height of the connecting parts and plug-in parts on both sides. The height of the connecting part is lower than the height of the plug-in part. The connecting part, positioning part, and plug-in part are all formed by punching and bending.

[0012] Furthermore, the connecting part has elongated punched holes on both sides of its side walls, and the upper ends of both sides of the connecting part are bent inward at 90° to form a horizontal shape, with the ends abutting to form a rectangular shell; the bottom center of the positioning part has a first U-shaped hole punched in, and the free end of the first punched part is bent inward and upward to form an upright shape; the upper part of both sides of the positioning part has a second U-shaped hole punched in, and the free end of the second punched part is inclined towards the inner cavity.

[0013] Furthermore, the upper part of both sides of the plug-in part is bent inward twice to form an upper bend. The two upper bends are X-shaped and opposite each other, and the gap between them forms an upper plug-in space. The bottom end of the plug-in part is an L-shaped edge, and the roots of the two L-shaped edges are bent inward towards the cavity. The upper and lower ends of the two L-shaped edges are bent to the sides to form lower bends, and the upper end of the lower bends extends into the interior of the upper bends. The two lower bends are X-shaped and opposite each other, and the gap between them forms a lower plug-in space. The upper plug-in space and the lower plug-in space are directly opposite each other, and the gap between them is smaller than the diameter of the keyboard switch.

[0014] The technological advancements achieved by this invention compared to existing technologies are as follows:

[0015] This invention, by misaligning two terminals within a hollowed-out area of ​​the material plate, allows the two terminals to align with the two misaligned signal pins of the hot-swappable shaft during assembly. This facilitates the simultaneous assembly of multiple pairs of terminals, significantly increasing assembly efficiency and improving the stability and consistency of assembly dimensions, thereby raising the product yield. The multi-terminal design increases terminal connection strength and facilitates simultaneous electroplating of multiple sets, greatly reducing electroplating labor costs and ultimately lowering electroplating costs. This invention features a compact structure, good versatility, high compatibility, and is easy to promote and apply. Attached Figure Description

[0026] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown in the figure, this utility model provides a combined terminal structure for a hot-swappable keyboard, including a material plate 1 and one or more terminal groups 00. Each terminal group 00 includes two terminals 100, which are disposed in a hollow area 2 on the material plate. The two terminals 100 are arranged opposite to each other and connected to the material plate 1. The two terminals 100 are staggered according to the size of the keyboard shaft pins they contact, so as to correspond to the two staggered signal pins of the hot-swappable shaft. The material plate 1 includes one or more parallel elongated strips 11. Each terminal group 00 has a bridge strip 12 on both sides connecting the two parallel strips 11. The two strips 11 and the two bridge strips 12 surround each other to form the hollow area 2. Figure 1 The illustrated embodiment features four terminal groups, the number of which can be designed according to actual needs. In this structure, the terminals, arranged in pairs, form a unified whole with the surrounding material strips and bridge strips, facilitating the simultaneous assembly of multiple pairs of terminals with the signal pins of multiple keyboard switches. This improves assembly efficiency and dimensional stability, significantly increasing the product yield.

[0028] As a preferred structure, the terminal 100, bridge strip 12, and material strip 11 are integrated into a single piece of flat sheet metal. During design, the center lines of the two terminals in each terminal group are staggered to match the corresponding keyboard pivot centers, improving assembly accuracy. In actual manufacturing, a high-speed punch press and high-speed electric cylinder are used on a flat sheet metal to achieve high-speed punching and die assembly. This operation is similar to the principle of continuous stamping dies, completing terminal processing and assembly, terminal riveting, and scrap cutting in one set of actions. The material strip, bridge strip, and terminal formed by a single punching and bending process simplify the overall structure, improve overall strength, reduce material input costs, and further reduce production costs. Compared to traditional segmented cylinder assembly, efficiency is increased several times, significantly reducing assembly process costs.

[0029] In specific manufacturing, the strip 11 has a row of connecting holes 3 for easy fixing of the material plate; there are two or more pairs of strips 11, with adjacent strips 11 forming an integral structure and adjacent rows of connecting holes 3 arranged alternately; two adjacent sets of terminal groups 00 are separated by a bridge strip 12. This structure can be expanded into multiple sets, allowing for the assembly of multiple products at once, greatly increasing assembly efficiency, reducing assembly costs, and avoiding the potential for dimensional instability caused by the cumulative assembly difference between two assemblies. This multi-strip structure also increases the terminal connection strength, allowing for simultaneous electroplating during subsequent surface treatment, reducing the risk of electroplating deformation, saving considerable labor costs, significantly reducing the cost of subsequent electroplating, and enhancing product competitiveness.

[0030] Further optimize the above solution, such as Figure 1 As shown, a row of positioning holes 4 is provided between two adjacent rows of connecting holes 3, and the positioning holes 4 are arranged alternately with the connecting holes 3. The positioning holes can be used to position the material plate and terminals, and at the same time meet the requirements of lightweight design.

[0031] In specific embodiments of this utility model, such as Figure 2-4 As shown, the terminal 100 is divided into a connecting part 110, a positioning part 120, and a plug-in part 130 along its length. The connecting part 110 is used to connect to the material plate 1 and can be soldered to the keyboard circuit. The positioning part 120 is used to connect to the keyboard switch base. The plug-in part 130 is used to clamp the keyboard switch. The bottoms of the connecting part 110, the positioning part 120, and the plug-in part 130 are flush. The height of the positioning part 120 is lower than the height of the connecting parts 110 and the plug-in part 130 on both sides. The height of the connecting part 110 is lower than the height of the plug-in part 130. The connecting part 110, the positioning part 120, and the plug-in part 130 are all punched and bent, resulting in high overall strength.

[0032] In specific processing, such as Figure 2 , 3As shown, the connecting part 110 has elongated punched holes 101 penetrating both the inside and outside on its two side walls. The upper ends of the two side walls of the connecting part 110 are bent inward at 90° to form a horizontal shape, and the ends abut against each other to form a rectangular shell. The bottom center of the positioning part 120 has a first U-shaped hole 102 punched in, and the free end of the first punched part 103 is bent inward and upward to form an upright shape. The upper part of the two side walls of the positioning part 120 has a second U-shaped hole 104 punched in, and the free end of the second punched part 105 is inclined towards the inner cavity. This structure can improve the strength of the connecting part and the positioning part.

[0033] like Figure 4 As shown, the upper parts of both sides of the insertion part 130 are bent inward twice to form upper bends 106. The two upper bends 106 are X-shaped and opposite each other, and the gap between them forms an upper insertion space 107. The bottom end of the insertion part 130 is an L-shaped edge, and the roots of the two L-shaped edges are bent inward towards the cavity. The upper and lower ends of the two L-shaped edges are bent outward to form lower bends 108, and the upper end of the lower bends 108 extends into the interior of the upper bends 106. The two lower bends 108 are X-shaped and opposite each other, and the gap between them forms a lower insertion space 109. The upper insertion space 107 and the lower insertion space 109 are vertically aligned, and the gap between them is smaller than the diameter of the keyboard switch. When the keyboard switch is inserted into the upper insertion space and the lower insertion space, the elasticity of the upper and lower bends on both sides clamps the upper and lower parts of the keyboard switch firmly at the same time. Both the upper and lower bends on both sides have a certain degree of elasticity, which can accommodate keyboard switches of different diameters. Moreover, the wider the upper and lower bends are, the greater the clamping force on the keyboard switches.

[0034] In summary, this utility model has the advantages of simple and compact structure and convenient and quick assembly. The terminals are arranged in pairs with staggered placement in the hollow area of ​​the material plate. During assembly, the two staggered signal pins of the hot-swappable shaft are inserted into the upper and lower insertion spaces of the terminals, respectively. The upper and lower parts of the keyboard shaft are clamped by the elastic force of the upper and lower bending parts on both sides. This structure allows for the assembly of multiple sets of terminals at once, significantly increasing assembly efficiency, reducing the labor intensity of workers, improving assembly accuracy and consistency, and increasing the product qualification rate. Simultaneously, multiple assembly groups facilitate subsequent electroplating, greatly reducing electroplating time and costs. Furthermore, it possesses the advantages of good versatility and high compatibility, making it easy to promote and apply.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
