Description

Technical Field

[0001] This utility model belongs to the field of chassis module plug-in technology, and specifically relates to a universal module plug-in aid structure. Background Technology

[0002] For applications using miniaturized VPX chassis, the internal modules also need to be miniaturized. Commonly used modules include standard 3U VPX modules, VITA 74 modules, and customized non-standard modules. Taking a standard 3U VPX module as an example, its dimensions are as follows: Figure 1 , Figure 2 , Figure 3 As shown, the module is in the following plug-in and locking state. Figure 4 As shown, the module consists of a cold plate structure, a VPX connector, a puller, and a locking strip. The chassis has a boss. During module insertion, the puller uses leverage to assist in the insertion process. However, due to the limited width of the miniaturized module, only one puller can be installed, assisting insertion on one side only. This can easily lead to incomplete insertion of the VPX connector on the other side, causing one side of the module to tilt upwards. This is especially problematic for miniaturized VPX connectors, where the insertion and extraction force requirements are high within a limited space, making the upward tilting issue even more pronounced. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model proposes a universal module insertion aid structure that enables balanced insertion of auxiliary modules within a miniaturized chassis and allows for detachable installation.

[0004] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a universal module insertion aid structure includes a fixed slider detachably mounted on a chassis side panel. The fixed slider includes a mounting portion detachably mounted on the chassis side panel and an insertion aid portion inside the chassis for assisting module insertion. The thickness of the insertion aid portion in the module insertion direction is greater than that of the mounting portion. The protruding portion of the insertion aid portion relative to the mounting portion is used to contact the side of the module away from the puller. The mounting portion is also provided with mounting holes for passing through set screws. The fixed slider is detachably mounted on the chassis side panel by set screws.

[0005] As an improvement to the above technical solution, the mounting hole is an elongated hole.

[0006] As a further improvement to the above technical solution, the insertion aid is also provided with a clearance ring groove for avoiding the locking bar.

[0007] As a further improvement to the above technical solution, the avoidance ring groove is a long strip-shaped through groove opened on the insertion part.

[0008] As a further improvement to the above technical solution, a flexible rubber pad is also provided on the side of the insertion aid that contacts the module.

[0009] As a further improvement to the above technical solution, a groove is provided on the side of the insertion aid that contacts the module, and the flexible pad is disposed in the groove, the height of the flexible pad being greater than the depth of the groove.

[0010] As a further improvement to the above technical solution, the side panel of the chassis is bent inward at the module insertion port to form a fastening edge, and a number of screw holes adapted to the set screws are provided at intervals along its length on the fastening edge.

[0011] The beneficial effects of this utility model through the above technical solution are: 1. The universal module insertion aid structure of this utility model achieves the auxiliary insertion of the module during the installation of the chassis module by setting a fixed slider with an installation part and an insertion aid part and a set screw, which avoids the situation that the module cannot be inserted properly in the chassis. After insertion, it can be removed by simple operation, avoiding the occupation of space inside the chassis.

[0012] 2. This utility model provides several universal module insertion aids at the corresponding positions of the module installation in the chassis. These several detachable universal module insertion aids simultaneously press and assist the module at both ends of the module installation position, avoiding the problem of the module tilting upwards on one side due to incomplete insertion on the other side when only one side is assisted.

[0013] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, preferred embodiments are given below, and detailed descriptions are provided in conjunction with the accompanying drawings.

[0024] Reference Figure 5 , Figure 6 A general-purpose module insertion aid structure includes a fixed slider 1 and a set screw 2. The set screw enables the fixed slider 1 to be installed in an adjustable and detachable manner on the side panel 4 of the chassis. The position of the fixed slider on the side panel 4 is adjusted to assist in the insertion of the module 5 into the chassis. This auxiliary insertion structure is not only small in size and can be adjusted at the existing edge mounting position of the side panel 5, but it can also be removed after use, avoiding the occupation of space inside the chassis.

[0025] Specifically, the fixed slider 1 includes a mounting part 11 for detachable installation on the side panel 4 of the chassis and an insertion aid 12 for inserting the auxiliary module 5 inside the chassis. The thickness of the insertion aid 12 in the insertion direction of the module 5 is greater than that of the mounting part 11, and the protruding portion of the insertion aid 12 relative to the mounting part 11 is used to contact the side of the module away from the puller. The mounting part 11 is also provided with a mounting hole 13 for passing through a set screw 2. The fixed slider 1 is detachably mounted on the side panel 4 of the chassis by the set screw 2. When in use, the fixed slider 1, which is installed by the set screw 2, can be moved within the chassis towards the installation position of the module 5 by tightening and loosening the set screw 2, thereby enabling the fixed slider 1 to push the module 5 and allow the module 5 to be inserted into the installation position.

[0026] In order to enable the fixed slider 1 to adapt to different sizes of chassis and to be installed at the edge of different chassis sides, the mounting hole 13 is an elongated hole. The structure of the elongated hole allows the position of the set screw 2 to be adjusted within the hole, so that the set screw 2 can correspond to the screw hole 42 provided at the edge of the side plate 4 of different models of chassis.

[0027] Reference Figures 1-4 As one embodiment of this application, the aforementioned universal module insertion aid structure can be installed in a miniaturized VPX chassis. Commonly used modules 5 include standard 3U VPX modules 5, VITA 74 modules 5, and customized non-standard modules 5. In this embodiment, the chassis includes a cold plate structure 8, a VPX connector 9, a pull-out device 6, and a locking strip 7. The chassis also has a side panel 4, and the modules 5 are inserted into the chassis within the area enclosed by the side panel 4. The universal module insertion aid structure can be installed on the side panel 4 to facilitate the insertion of the modules 5 within the chassis.

[0028] Reference Figure 7 In this embodiment, the side panel of the chassis is bent inward at the module insertion port to form a fastening edge 41. The fastening edge 41 is provided with screw holes 42. Several general module insertion auxiliary structure fixing sliders 1 are detachably set in the screw holes 42 on the side panel of the chassis by set screws 2, and assist the insertion of the module 5 in the chassis on the side panel of the chassis.

[0029] In this embodiment, each general module 5 is provided with two set screws 2, and the two set screws 2 are respectively used to adjust and fix the fixed slider 1 at both ends of the elongated hole.

[0030] In this embodiment, to prevent module 5 from tilting upwards on one side after insertion, the set screw 2 passes through the mounting hole 13 and is detachably connected to the snap-fit ​​edge 41 of the chassis side panel at the module insertion port. The fixing slider 1 is positioned on the edge of the chassis side panel corresponding to the side of module 5 furthest from the puller 6. During module 5 insertion, one side of module 5 is assisted in insertion by the insertion aid 12, while the other side is assisted by the puller 6. The contact position between the insertion aid 12 and module 5 limits the movement of module 5. When the other side of the module is assisted by the puller, the limitation imposed by the insertion aid 12 also prevents module 5 from tilting upwards on one side due to force applied to that side.

[0031] In this embodiment, a locking strip 7 for locking the module 5 is also provided at the installation position of the module 5. When the fixing slider 1 assists in the insertion of the module 5, it will affect the locking of the locking strip 7. The locking strip 7 is used for locking the module 5 after insertion. Therefore, the insertion assistance part 12 is also provided with an avoidance ring groove 14 for avoiding the locking of the module 5. The avoidance ring groove 14 is an elongated through groove opened on the insertion assistance part 12. The locking strip 7 corresponds to the avoidance ring groove 14 of the module insertion assistance structure in the vertical direction.

[0032] In addition, a groove is provided on the side of the insertion aid 12 that contacts the module 5, and a flexible rubber pad 3 is disposed in the groove. The height of the flexible rubber pad 3 is greater than the depth of the groove. In this embodiment, the groove is located on one side of the avoidance ring groove and the two are parallel and corresponding.

[0033] In other embodiments of this application, each general module insertion aid structure may have only one set screw 2 or more than two. When the set screw 2 is set to a single screw, it is convenient to disassemble the fixed slider 1. When it is set to multiple screws, the installation of the fixed slider 1 can be more stable, and the force applied during the insertion process of the module 5 can be more balanced and stable.

[0034] In other embodiments of this application, the groove at the bottom of the insertion aid 12 can also be configured as an annular groove along the edge of the avoidance annular groove 14, and the annular flexible pad 3 contacts the module 5, further increasing the balance and stability of the force on the module 5 during the assisted insertion process.

[0035] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the technical scope of this utility model and based on its technical essence shall still fall within the scope of this utility model.
