Description

Technical Field

[0001] This utility model relates to a floating connector device, and more particularly to a floating connector device for plugs and sockets used in data centers, such as plugs or sockets for connecting to GPUs. Background Technology

[0002] In GPU connection, multiple plugs are arranged in an array on the base to form a module, which is then plugged into the GPU socket in one go from top to bottom or from bottom to top.

[0003] To compensate for positional errors of the plugs in the module, each plug is equipped with an X-axis and / or Y-axis guide sliding mechanism and a guide post. With the cooperation of the guide pin and the socket in the socket, the plug is guided to adaptively adjust the terminal position on the corresponding X-axis and / or Y-axis.

[0004] This guiding sliding mechanism consists of a Z-axis pin passing through an X-axis or Y-axis slot, which slides under the drive of the guide pin and the socket. Although the plug is inserted in the Z-axis (up or down), the data cable connected to the plug enters from both sides and connects to the terminal. Therefore, the weight of the data cable will exert a biased pulling force on the plug, causing "off-center loading". This will cause the pin and slot surface in the off-center loading direction to be excessively squeezed, resulting in poor sliding or wear and jamming. Moreover, since the plugs in the module are distributed in an array, the tolerance directions of each plug are inconsistent. Therefore, when inserting the module, the adjustment direction of each plug is different. Poor sliding adjustment or jamming will not only make the operation difficult, but also cause the adjustment speed of each plug to be different, resulting in the whole module not being able to be inserted into place.

[0031] In this invention, the directions of the X-axis, Y-axis, and Z-axis are shown in the figure. The Z-axis represents the insertion / removal direction of the plug, and the X-axis and Y-axis are perpendicular to the Z-axis. This embodiment uses a plug as an example, and the plug-in assembly is a wire harness terminal.

[0032] Referring to the accompanying drawings, the floating connector device of this embodiment includes a terminal mounting bracket 3 (i.e., a connector mounting bracket) and a mounting component for the connector mounting bracket; the floating connector device is also provided with a base 4, and a Z-direction support spring 5 is provided between the base 4 and the mounting component for the connector mounting bracket to provide a Z-direction floating function.

[0033] In this embodiment, the mounting components of the plug-in assembly mounting bracket include a lifting frame 1 and an intermediate frame 2. The intermediate frame 2 and the lifting frame 1 are provided with holes 10 and 20 for the wire harness 200 to pass through. A Z-axis support spring 5 is provided between the base 4 and the lifting frame 1, so that the lifting frame 1, the intermediate frame 2, and the terminal mounting bracket 3 (including the wire harness terminal 100 in the terminal mounting bracket) connected together in the Z-axis can float as a whole in the Z-axis. In this embodiment, a Z-axis limiting screw 51 is provided. The limiting screw is threadedly connected to the lifting frame 1. The support spring 5 is sleeved on the Z-axis limiting screw 51 and supported between the base 4 and the lifting frame 1. The base 4 is provided with a hole for the limiting screw 51 to pass through, and the head of the limiting screw and the base 4 form a limiting fit.

[0034] The floating connector is equipped with an X-axis displacement mechanism on the first pair of sides and a Y-axis displacement mechanism on the second pair of sides. The first and second pairs of sides are the four sides of a rectangle. The relative motion pair formed by the lifting frame 1 and the intermediate frame 2 is equipped with the Y-axis displacement mechanism, while the relative motion pair formed by the intermediate frame 2 and the terminal mounting frame 3 is equipped with the X-axis displacement mechanism. A guide post 30 with a tapered needle is provided on the top of the terminal mounting frame 3. When the plug is inserted into the socket, the guide post 30 first guides and engages with the hole on the socket. When there is partial misalignment, the X-axis displacement mechanism and / or the Y-axis displacement mechanism can make corresponding linear displacement adjustments through the guidance of the tapered surface of the guide post 30, causing the terminal mounting frame 3 (including the connecting terminal 100 in the terminal mounting frame) to float in the X and / or Y directions. This floating performance will not cause jamming or floating jamming problems due to the lateral tension F or off-center load of the wire harness 200.

[0035] The X-axis and Y-axis displacement mechanisms employ the rolling friction linear track of this invention. Each rolling friction linear track includes a rolling mechanism and a linear raceway that engages with the rolling mechanism through rolling friction. The linear raceway and the rolling mechanism form a locking relationship in the Z-axis direction. The reference numeral for the rolling mechanism of the X-axis displacement mechanism is 61, and the reference numeral for the linear raceway is 62; the reference numeral for the rolling mechanism of the Y-axis displacement mechanism is 71, and the reference numeral for the linear raceway is 72. During X-axis displacement adjustment and / or Y-axis displacement adjustment, the rolling mechanism 61 and the linear raceway 62 and / or the rolling mechanism 71 and the linear raceway 72 undergo relative displacement and corresponding floating. Since it is a rolling friction mechanism, the sliding in the X and Y directions is smooth, and there will be no jamming or floating jamming problems caused by the lateral tension F or off-center load of the wiring harness 200.

[0036] The linear raceways 62 and 72 of the X-axis and Y-axis displacement mechanisms are mounted on the intermediate frame 2, located on the four sides of a rectangular frame, which is rectangular in shape. The rolling mechanism is mounted on another component (terminal mounting frame 3 or lifting frame 1) that forms a relative motion pair with the intermediate frame 2, located at the lower end of the terminal mounting frame 3 and the upper end of the lifting frame 1. The parts 34 and 11 of the terminal mounting frame 3 and the lifting frame 1 that connect to the rolling mechanism are located inside the intermediate frame 2 for easy assembly.

[0037] The linear raceways 62 and 72 are configured as limiting grooves open to the side of the floating insertion device. Each limiting groove includes a top raceway surface R1 and a bottom raceway surface R2 that engage with the rolling mechanism through rolling friction, as well as limiting ends R3 on both sides of the limiting groove. Using this invention, the cooperation between the linear raceways and the rolling mechanism also serves as a limiting structure for the floating displacement, thus eliminating the need for a separate limiting mechanism. Furthermore, it facilitates the installation or maintenance of the rolling mechanisms 61 and 71 from the outside.

[0038] The X-axis displacement mechanism's linear raceway 62 and the Y-axis displacement mechanism's linear raceway 72 are arranged in multiple segments along the length of the rectangular side, which also serve as a balance support while achieving the limiting function.

[0039] like Figures 1 to 6 As shown, in this embodiment, the rolling mechanisms 61 and 71 include a central connecting shaft M1 and a rotating outer ring M2 sleeved on the central connecting shaft M1. The rotating outer ring is rotatably positioned on the central connecting shaft. One end of the central connecting shaft M1 is a threaded connecting post M4, and the other end is a limiting and screw-operated structure M5. The middle section is a mounting section M3 corresponding to the rotating outer ring M2. The threaded connecting post M4 is threadedly connected to the terminal mounting bracket 3 or the lifting bracket 1 at the part connected to the rolling mechanism. In this embodiment, the mounting section M3 and the rotating outer ring M2 are rotatably connected by ball bearings M6. Figure 7 , 8As shown, the rotating mechanism adopts another implementation method. One end of its central connecting shaft is a threaded connecting post M4, and the other end is a limiting and screw operating structure M5. The middle section is the mounting section M3b corresponding to the rotating outer ring M2b. The threaded connecting post M4 is threadedly connected to the terminal mounting bracket 3 or the part of the lifting bracket 1 that connects to the rolling mechanism. In this embodiment, the rotating outer ring M2b is a bushing, directly fitted onto the mounting section M3b for rotational connection. Other structures and... Figures 1 to 6 The same as Example 1 shown. As... Figure 9 , 10 The rotating mechanism adopts a third implementation method, which, based on embodiment 2, shows that the outer rotating ring M2c engages with the V-shaped or trapezoidal convex rail P on the straight raceway via a V-shaped or trapezoidal straight groove M7 on its outer surface, allowing it to roll along the V-shaped convex rail. Other structures are the same as in embodiment 2. All the aforementioned outer rotating rings engage with the straight raceway through rolling friction. For example... Figure 11 , 12 As shown, the rotating mechanism adopts the fourth embodiment. The rotating mechanism uses steel balls M8, which are rotatably disposed in the mounting hole 21 on the outer side of the intermediate frame 2d, directly engaging with the straight raceway M9 through rolling friction. The mounting hole 21 and the straight raceway M9 each have supporting portions M211 and M91 that engage with the lower apex M82 and upper apex M81 of the steel balls, respectively, providing better support and preventing dents on the side of the straight raceway M9 from affecting rolling smoothness. In this embodiment, a floating displacement limiting mechanism is provided, including a limiting screw 22 connected to the intermediate frame 2d and a limiting hole 35 (or a limiting hole on the lifting frame) disposed on the terminal mounting bracket 3. The outer end of the limiting screw 22 and the limiting hole 35 form a limiting engagement in the floating direction.

[0040] The X-axis displacement mechanism and the Y-axis displacement mechanism can also adopt different schemes, such as Figure 13 As shown, in this embodiment, the Y-axis displacement mechanism adopts the scheme of Embodiment 4, and the X-axis displacement mechanism adopts the scheme of Embodiment 1.

[0041] The rolling mechanism can also be set on the sliding frame, and straight raceways that roll frictionally engage with the rolling mechanism are provided on the first and second components that constitute the relative kinematic pair. The rolling mechanism can be a rolling element.

[0042] The terminal mounting bracket 3 has a rectangular structure, including a frame base 31 with three rectangular sides and a cover plate 32 serving as the other side of the terminal mounting bracket. The cover plate 32 and the frame base 31 are connected to form the terminal mounting bracket 3. The straight rollers 62 provided on the terminal mounting bracket 3 are located at the lower ends of the upright plates 311 on both sides of the frame base. The wire harness terminals 100 provided on the plug are connected to the connection holes 33 provided on the cover plate 32 and the frame base 31.
