Description

A floating anti-detachment structure for AMC panels Technical Field

[0001] This utility model belongs to the technical field of electronic device connection structure, specifically relating to a floating anti-detachment structure for AMC panels. Background Technology

[0002] Currently, in the field of electronic equipment, misalignment frequently occurs during the mating process between AMC panels and MTCA chassis, and gaps easily form between the connectors upon contact. This directly leads to frequent power outages and poor contact during equipment operation, severely affecting normal use. To achieve a reliable connection between AMC panels and MTCA chassis, existing technologies typically require the production of structural components in various sizes to ensure that the AMC panel can fit different chassis models, thereby ensuring a secure connection between the AMC panel and the chassis backplane. However, this approach has many drawbacks, not only significantly increasing production costs but also making chassis replacement extremely cumbersome, difficult to guarantee product consistency, unable to achieve mass production, and unable to meet flexible interchangeability requirements. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a floating anti-detachment structural component for AMC panels, which solves the problems of poor versatility and low flexibility of the structural components used in existing AMC panels.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a floating anti-detachment structural component for an AMC panel, comprising a structural plate that can be connected to the AMC panel and several fasteners that are movably connected to the structural plate;

[0005] The structural plate includes a U-shaped structural plate and two extension plates that are slidably connected to the inner side of the U-shaped structural plate. The extension plates are provided with strip-shaped through holes along their sliding direction. The U-shaped structural plate is provided with limiting through holes corresponding to the strip-shaped through holes. The U-shaped structural plate and the extension plates are connected and fixed by bolt assemblies that can pass through the strip-shaped through holes and the limiting through holes.

[0006] The extension plate has an ear hole at one end for installing the fastener. The fastener includes a hollow tube that is floatingly connected to the ear hole and a hand-tightening bolt that is threadedly connected to and passes through the hollow tube. The hand-tightening bolt can be threadedly connected to the back panel of the chassis, and one end of the hand-tightening bolt can abut against the end of the hollow tube.

[0007] Optionally, the hollow tube is provided with an upper riveting limiting part and a lower riveting limiting part on its outer periphery, and a section of the hollow tube located between the upper riveting limiting part and the lower riveting limiting part can pass through the ear hole, with a gap between the outer periphery of this section and the inner wall of the ear hole; and the distance between the upper riveting limiting part and the lower riveting limiting part is greater than the depth of the ear hole, and the outer diameter of the upper riveting limiting part and the lower riveting limiting part is greater than the inner diameter of the ear hole.

[0008] Optionally, one side of the extension plate can be abutted against the back panel of the chassis, and a rubber pad layer is provided on the side of the extension plate that can abut against the back panel of the chassis.

[0009] Optionally, the head diameter of the hand-tightening bolt is larger than the inner diameter of the hollow tube, and the outer periphery of the head of the hand-tightening bolt is provided with anti-slip texture.

[0010] Optionally, a sealing gasket is fitted around the outer periphery of a section of the hollow tube positioned between the upper riveting limiting part and the lower riveting limiting part.

[0011] Optionally, the hand-tightened bolt can be threaded onto one end of the chassis back panel in a tapered shape.

[0012] Optionally, the U-shaped structural plate is a one-piece sheet metal component.

[0013] Optionally, the bolt assembly includes a bolt capable of passing through the strip-shaped through hole and the limiting through hole, and a nut threaded onto the bolt, wherein the outer periphery of the nut is provided with anti-slip texture.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by using a sliding extension plate in conjunction with a U-shaped structural plate, and combining the strip-shaped through hole and the limiting through hole with the bolt assembly, the fasteners on the two extension plates can be flexibly adjusted in position. This allows the AMC panel to be adapted to different specifications of AMC panels through the floating anti-detachment structure in this technical solution. At the same time, it can also reduce the operation steps of replacing the chassis of the AMC panel and meet the flexible interchangeability requirements. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] As shown in Figures 1-4, a floating anti-detachment structural component for an AMC panel includes a structural plate that can be connected to the AMC panel and several fasteners that are movably connected to the structural plate. The structural plate includes a U-shaped structural plate 1 and two extension plates 2 that are slidably connected to the inner side of the U-shaped structural plate 1. Specifically, the U-shaped structural plate 1 can be connected to the AMC panel using existing connection methods such as magnetic connection, snap-fit ​​connection, riveting connection, hinge connection, press-fit connection, and dovetail groove connection. As shown in Figure 1, when the extension plates 2 are placed inside the U-shaped structural plate 1, due to the U-shaped cross-sectional structure of the U-shaped structural plate 1, the extension plates 2 can slide along a fixed direction. The extension plate 2 has a strip-shaped through hole 201 along its sliding direction, and the U-shaped structural plate 1 has a limiting through hole 101 corresponding to the strip-shaped through hole 201. The U-shaped structural plate 1 and the extension plate 2 are connected and fixed by a bolt assembly 3 that can pass through the strip-shaped through hole 201 and the limiting through hole 101. One end of the extension plate 2 has an ear hole 202 for installing fasteners. The fasteners include a hollow tube 4 that is floatingly connected to the ear hole 202 and a hand-tightening bolt 5 that is threaded and passes through the hollow tube 4. The hand-tightening bolt 5 can be threaded to the back panel of the chassis, and one end of the hand-tightening bolt 5 can abut against the end of the hollow tube 4. It should be noted that the bolt assembly 3 is existing technology, consisting of a bolt 301 and a nut 302. When the nut 302 threaded onto the bolt 301 is loosened, the position between the extension plate 2 and the U-shaped structural plate 1 floats relative to each other, and the distance the extension plate 2 extends from the U-shaped structural plate 1 can be adjusted. When the nut 302 threaded onto the bolt 301 is tightened, the position between the extension plate 2 and the U-shaped structural plate 1 is relatively fixed. Therefore, by adjusting the distance the extension plate 2 extends from the U-shaped structural plate 1, it is possible to adjust the position so that the hand-tightening bolt 5 on the extension plate 2 can correspond to the pre-drilled mounting holes (not shown in the figure) on the back panel of different models and specifications of the chassis, thereby increasing the compatibility of the AMC panel.

[0024] Furthermore, as shown in Figure 2, the hollow tube 4 is provided with an upper riveting limiting part 401 and a lower riveting limiting part 402 on its outer periphery. A section of the hollow tube 4 positioned between the upper riveting limiting part 401 and the lower riveting limiting part 402 can pass through the ear hole 202, with a gap between the outer periphery of this section and the inner wall of the ear hole 202. The distance between the upper riveting limiting part 401 and the lower riveting limiting part 402 is greater than the depth of the ear hole 202, and the outer diameter of the upper riveting limiting part 401 and the lower riveting limiting part 402 is greater than the inner diameter of the ear hole 202. This allows the hollow tube 4 and the hand-tightening bolt 5 to move within a small range relative to the extension plate 2, further improving the accurate alignment and threaded connection between the hand-tightening bolt 5 and the pre-drilled mounting holes on the chassis back plate.

[0025] It is important to note that before threading the hand-tightening bolt 5 into the pre-drilled mounting hole on the chassis back panel, the hollow tube 4 can be manually supported to keep it relatively stationary relative to the hand-tightening bolt 5. Then, the hand-tightening bolt 5 can be turned until one end of the bolt 5 abuts against the end of the hollow tube 4. Furthermore, in this technical solution, the internal thread direction of the hollow tube 4 is consistent with the internal thread direction of the pre-drilled mounting hole on the chassis back panel. This ensures that when the hand-tightening bolt 5 is further turned until it is threaded into the mounting hole, the hollow tube 4 rotates synchronously with the hand-tightening bolt 5 until it is securely threaded into the mounting hole. The upper riveting limit part 401 on the hollow tube 4 then abuts tightly against the extension plate 2, and the extension plate 2 fits tightly against the chassis back panel, thus completing a stable connection between the AMC panel and the chassis back panel. Simultaneously, because the end of the hand-tightening bolt 5 that is threaded into the chassis back panel is tapered, the operator can quickly and accurately align the hand-tightening bolt 5 with the mounting hole.

[0026] As shown in Figure 2, a sealing gasket 6 is fitted around the outer periphery of a section of the hollow tube 4 between the upper riveting limit part 401 and the lower riveting limit part 402. The sealing gasket 6 is placed between the upper riveting limit part 401 and the extension plate 2. The sealing gasket 6 can buffer the pressure exerted by the upper riveting limit part 401 on the extension plate 2. At the same time, it can fill the gap between the ear holes 202 of the hollow tube 4 when the hand-tightened bolt 5 is screwed and tightened between it and the chassis back plate, so as to prevent dust and other impurities from entering the chassis through the ear holes 202.

[0027] As described above, one side of the extension plate 2 can be attached to the back panel of the chassis, and a rubber pad (not shown in the figure) is provided on the side of the extension plate 2 that can be attached to the back panel of the chassis to avoid direct rigid contact between the extension plate 2 and the back panel of the chassis.

[0028] As shown in Figures 1, 3, and 4, the bolt assembly 3 includes a bolt 301 that can pass through the strip-shaped through hole 201 and the limiting through hole 101, and a nut 302 that is threaded onto the bolt 301. The outer periphery of the nut 302 is provided with anti-slip texture to facilitate manual operation by the operator.

[0029] In this embodiment, the head diameter of the hand-tightening bolt 5 is larger than the inner diameter of the hollow tube 4, and the outer periphery of the head of the hand-tightening bolt 5 is provided with anti-slip texture to facilitate manual operation by the operator.

[0030] In this technical solution, the U-shaped structural plate 1 is a sheet metal integral part, which can be manufactured by stamping and bending. It has high structural strength and is easy to promote.

[0031] It should be noted that the hollow tube 4 in this technical solution can be connected to the ear hole 202 by riveting.

[0032] Working principle: When the nut 302 threaded onto bolt 301 is loosened, the position between extension plate 2 and U-shaped structural plate 1 floats relative to each other, and the distance the extension plate 2 extends from the U-shaped structural plate 1 can be adjusted. When the nut 302 threaded onto bolt 301 is tightened, the position between extension plate 2 and U-shaped structural plate 1 is relatively fixed. Therefore, by adjusting the distance the extension plate 2 extends from the U-shaped structural plate 1, it is possible to adjust the position so that the hand-tightening bolt 5 on the extension plate 2 can correspond to the pre-drilled mounting holes (not shown in the figure) on the back panel of different models and specifications of the chassis, thereby increasing the compatibility of the AMC panel.

[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
