[0002] In modern electronic equipment and mechanical assembly, especially in assembly involving board-to-board connections, ensuring tight fit between components is crucial. However, due to part tolerance stacking and dimensional deviations, loose components or improper fit often occur during assembly. This can lead to poor connections, functional failures, or decreased overall component performance.

[0003] For example, in automotive electronics, radios, navigation systems, and other electronic devices are often housed in metal enclosures (silver boxes) to provide electromagnetic shielding. However, when assembling the panel assembly with the silver box and other components, mechanical tolerances and dimensional variations between the panel and silver box can lead to loose or incomplete assembly. This problem not only affects the appearance of the device but can also cause electrical connection failure.

[0029] Figure 2A FIG2 is a cross-sectional view illustrating a threaded connection assembly 200 according to one or more embodiments of the present invention. The threaded connection assembly 200 includes a screw 100, a first component 210, and a second component 260. The first component 210 includes a support structure 220. The second component 260 includes a threaded hole 270. The shank 120 of the screw 100 engages with the threaded hole 270 of the second component 260, and the screw head 110 presses the support structure 220 of the first component 210 against the second component 260, thereby securing the first component 210 to the second component 260 along the axis of the screw 100. Figure 2A The first component 210 and the second component 260 shown are schematic. In one or more embodiments according to the present invention, the first component 210 and the second component 260 can be any suitable electronic or mechanical components that need to be connected together.

[0030] Figure 2B and Figure 2C2 is a perspective view of a threaded connection assembly 200, wherein the second assembly 260 is omitted to illustrate the support structure 220 of the first assembly 210. As shown in the figure, the support structure 220 includes an opening 230. The opening 230 is an elongated opening and has a length direction. The screw 120 of the screw 100 passes through the opening 230 of the support structure 220 and is threadedly connected to the threaded hole 270 of the second assembly 260 (at Figure 2B and 2C (not shown). In the assembled position of the threaded connection assembly 200, the length direction of the opening 230 of the support structure 220 is perpendicular to the axial direction of the screw 100. The opening 230 of the support structure 220 includes a first linear edge or upper edge 232 and a second linear edge or lower edge 234 along its length. The support structure 220 also includes a linear rack 240 formed on the first linear edge or upper edge 232 of the opening 230. In one or more other embodiments, the linear rack 240 can be formed on the second linear edge or lower edge 234.

[0031] exist Figures 2A-2C In the position shown, the screw 120 of the screw 100 engages with the threaded hole 270 of the second component 260, and the circular gear 130 of the screw 100 engages with the linear rack 240 on the opening 230 of the support structure 220. When the screw 100 is rotated in the first direction or clockwise, the screw 120 of the screw 100 is further screwed into the threaded hole 270 of the second component 260, thereby further pressing the support structure 220 of the first component 210 against the second component 260. At the same time, the circular gear 130 of the screw 100 is engaged with the linear rack 240 on the opening 230 of the support structure 220. Figure 2B Arrow 2B and Figure 2C The linear rack 240 on the opening 230 of the bracket structure 220 is driven in the direction indicated by the arrow 2C, thereby driving the first component 210 to move relative to the second component 260 in the direction indicated by the arrow, thereby further tightening the first component 210 and the second component 260 in the direction indicated by the arrow.

[0032] During the tightening process of threaded connection assembly 200, shank 120 of screw 100 is first passed through opening 230 of support structure 220 and aligned with threaded hole 270 of second component 260. Screw 100 is then rotated in a first direction, or clockwise, to threadably engage shank 120 of screw 100 with threaded hole 270 of second component 260. At this point, only a portion of shank 120 of screw 100 is engaged with threaded hole 270 of second component 260. The circular gear 130 of screw 100 does not mesh with the linear rack 240 on opening 230 of support structure 220, and screw 100 operates in the same manner as a conventional screw without a circular gear 130.

[0033] As shown in the figure, the circular gear 130 occupies only a small portion of the length of the screw 120 at the root of the screw 120 of the screw 100. In one or more embodiments, the circular gear 130 occupies only about 1 / 5, about 1 / 8, about 1 / 10 or less of the length of the screw 120. As the screw 100 is gradually tightened, the circular gear 130 of the screw 100 begins to engage with the linear rack 240 on the opening 230 of the support structure 220. At this time, the further tightening of the screw 100 further presses the support structure 220 of the first component 210 against the second component 260 along the axial direction of the screw 100. At the same time, the circular gear 130 of the screw 100 is engaged with the linear rack 240 on the opening 230 of the support structure 220. Figure 2B Arrow 2B and Figure 2C The first component 210 and the second component 260 are further fastened in the direction indicated by the arrow 2C. In one or more embodiments, the extension direction of the linear rack 240 ( Figure 2B Arrow 2B and Figure 2C The direction indicated by arrow 2C is perpendicular to the axial direction of screw 100's shank 120, so screw 100 can fasten first component 210 and second component 260 in the axial direction of screw 100 and in another direction perpendicular to the axial direction. After threaded connection assembly 200 is tightened, the engagement or friction between threads 122 on shank 120 of screw 100 and threaded hole 270 of second component 260 prevents screw 100 from accidentally loosening, thereby ensuring a secure connection between first component 210 and second component 260.

[0034] Therefore, during the tightening process, the threaded connection assembly of the present invention can tighten the first component 210 to the second component 260 in two directions (i.e., the axial direction of the screw 100 and the extension direction of the linear rack 240 of the first component 210), so that even if there is a certain error between the first component 210 and the second component 260, it can ensure that the two are tightly combined in two directions.

[0035] In one or more embodiments, the circular gear 130 of the screw 100 is a helical gear including a helical tooth portion with a radial dimension gradually decreasing from the screw head 110 toward the screw shaft 120. The helical tooth portion can reduce the impact when the circular gear 130 initially contacts the linear rack 240.

[0036] Figures 2B-2C The support structure 220 and the opening 230 of the first component 210 shown are schematic. In one or more other embodiments of the present invention, the support structure 220 of the first component 210 and the opening formed in the support structure 220 can have any suitable form. For example, the support structure 220 of the first component 210 can have a different Figures 2B-2CAs long as the screw 100 can pass through the opening 230 therein to fasten the support structure 220 (and the first component 210) to the second component 260. The opening 230 of the support structure 220 can have a different shape than Figures 2B-2C The shape shown is any shape as long as it has first and second opposite linear edges, and a linear rack adapted to cooperate with the circular gear 130 of the screw 100 is provided on the first or second linear edge.

[0037] Figures 3A-3B A threaded connection assembly 300 according to one or more embodiments of the present invention is shown, wherein Figure 3A The threaded connection assembly 300 is shown in an assembled position, Figure 3B The screw 100 is removed from the figure to illustrate the structure that cooperates with the screw 100. The threaded connection assembly 300 includes a first component 310, a second component 360, and the screw 100. The first component 310 includes a first component body 312 and a support structure 320 fixedly connected to the first component body 312. The support structure 320 also includes an opening 330 and a linear rack 340 formed in the opening 330. The first component 310 also includes a first surface. The second component 360 includes a first surface and a second surface 364 that is perpendicular or substantially perpendicular to the first surface. In the assembled position shown in the figure, the first surface of the first component 310 and the first surface of the second component 360 are in contact with each other and abut against each other. The screw 100 passes through the opening 330 of the support structure 320 of the first component 310 and is threadedly connected to the threaded hole 370 on the second surface 364 of the second component 360.

[0038] In the final stage of tightening the threaded connection assembly 300, the screw rod of the screw 100 ( Figures 3A-3B 370 of the second component 360, and the circular gear (not shown) of the screw 100 is threadedly engaged with the threaded hole 370 of the second component 360, and the circular gear ( Figures 3A-3B (not shown) meshes with the linear rack 340 of the support structure 320 of the first component 310. Therefore, when the screw 100 is rotated in the first direction or clockwise, the screw rod of the screw 100 is threadedly engaged with the threaded hole 370 of the second component 360, and the support structure 320 and the first component 310 are fastened to the second component 360 along the axial direction of the screw 100. At the same time, the circular gear of the screw 100 is meshed with the linear rack 340 of the support structure 320 of the first component 310, and the support structure 320 and the first component 310 are fastened to the second component 360 along the axial direction of the screw 100. Figure 3A The direction indicated by arrow 3A causes the first surface of the first component 310 and the first surface of the second component 360 to be further attached together.

[0039] Therefore, even if there are some processing errors between the first component 310 and the second component 360 , the threaded connection component 300 of the present invention can firmly and tightly combine the first component 310 and the second component 360 in two directions.

[0040] Figure 4 A threaded connection assembly 400 according to one or more embodiments of the present invention is shown. The threaded connection assembly 400 includes a first component 410, a second component 460, and a screw 100. The first component 410 includes a first component body 412 and two bracket structures 420 fixedly connected to the first component body 412. Each bracket structure 420 includes an opening 430 and a linear rack formed in the opening 330. The first component 410 also includes a first face 416 and a circuit board connector 418 arranged on the first face 416. The second component 460 includes a first face 466 and a second face 464 perpendicular or substantially perpendicular to the first face 466. In the assembled position of the threaded connection assembly 400, the first face 416 of the first component 410 is mated and abutted against the first face 466 of the second component 460, and the circuit board connector 418 on the first face 416 is mated with a corresponding circuit board connector (not shown) on the second face 466. The screw 100 is threadedly connected to the threaded hole 470 on the second surface 464 of the second component 460 through the opening 430 of the support structure 420 of the first component 410 .

[0041] In the final stage of tightening the threaded connection assembly 400, the screw rod of the screw 100 is threadedly engaged with the threaded hole 470 of the second assembly 460, and the circular gear of the screw 100 is meshed with the linear rack of the support structure 40 of the first assembly 310. Therefore, when the screw 100 is rotated in the first direction or clockwise, the screw rod of the screw 100 is threadedly engaged with the threaded hole 470 of the second assembly 460, so that the support structure 420 and the first assembly 410 can be fastened to the second assembly 460 along the axial direction of the screw 100. At the same time, the meshing of the circular gear of the screw 100 with the linear rack of the support structure 420 of the first assembly 410 can be achieved. Figure 4 The first surface 416 of the first component 410 and the first surface 466 of the second component 460 are further pressed together in the direction indicated by the arrow 4A, ensuring a reliable connection between the circuit board connector 418 on the first surface 416 and the corresponding circuit board connector (not shown) on the first surface 466.

[0042] Therefore, even if there are some processing errors between the first component 410 and the second component 460 , the threaded connection component 400 of the present invention can firmly and tightly combine the first component 410 and the second component 460 in two directions.

[0043] exist Figure 4In the illustrated embodiment, first component 410 is a vehicle-mounted panel assembly, and second component 460 is a vehicle-mounted electronic device.
