DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0040] As an embodiment of the present application, Figure 2 the reference signs 1 and 2 in the embodiment of the present application, Figure 5 The numbers 5 and 6 are all "guide rail structures"; Figure 1 Reference numeral 20 denotes a guide rail unit; reference numeral 21 denotes an upper guide rail unit, and reference numeral 22 denotes a lower guide rail unit; the upper guide rail unit 21 and the lower guide rail unit 22 may be different from each other, and are not identical; the differences here are irrelevant to the technical concept of the present invention.

[0041] Example 1

[0042] The present application provides a guide rail structure comprising a guide rail unit, wherein the guide rail unit comprises at least two first and second grooves of different widths, the first and second grooves extending inwardly from the surface of the guide rail unit to different depths. The guide rail unit supports the insertion of SSDs of various shapes and is not limited to SSD testing, but can also be used to carry a variety of SSDs in use.

[0043] Example 2

[0044] like Figure 1 As shown, the present application provides a guide rail device supporting various forms of SSDs, including: a tray 100 and a guide rail structure 200, the guide rail structure 200 is installed on the tray 100; the tray 100 has a back plate ( Figure 1 (not shown in the figure), a plurality of connectors are arranged on the backplane; the guide rail structure 200 includes a guide rail unit 20 arranged on the tray 100, the guide rail unit 20 includes an upper guide rail unit 21 and a lower guide rail unit 22, and a storage space for inserting the SSD is formed between the upper guide rail unit 21 and the lower guide rail unit 22; the storage space includes multiple storage spaces, and the multiple storage spaces are distributed along the length direction of the tray 100, and one SSD can be inserted into each storage space. After the SSD is inserted into the storage space, the connector of the SSD forms an electrical connection with the connector on the backplane.

[0045] As a specific embodiment of the present invention, at least one guide rail structure 200 is provided on the pallet 100. A plurality of guide rail structures 200 may be provided on the upper side of the pallet 100, and all the guide rail structures 200 on the upper side are collectively referred to as the first group of guide rail structures. A plurality of guide rail structures 200 may be provided on the lower side of the pallet 100, and all the guide rail structures on the lower side are collectively referred to as the second group of guide rail structures. It can be understood that the first group of guide rail structures may include one or more guide rail structures 200. The second group of guide rail structures may include one or more guide rail structures 200. Thus, the plurality of guide rail structures jointly occupy the space (length) of the pallet in the left and right directions, so that the size of a single guide rail structure 200 does not need to change with the length of the pallet 100. The guide rail structure 200 can be used as a modular unit to adapt to pallets 100 of different sizes.

[0046] The first set of guide rail structures and the second set of guide rail structures are fixedly connected to the tray 100, and a storage space for inserting the SSD is formed between the first set of guide rail structures and the second set of guide rail structures. The first set of guide rail structures and the second set of guide rail structures are fixed to the upper and lower parts of the tray 100, respectively. Preferably, the first set of guide rail structures and the second set of guide rail structures are distributed up and down in the vertical direction and are both fixed to the tray 100. The first set of guide rail structures and the second set of guide rail structures each include a plurality of guide rail units 20 spaced apart along the length direction of the tray 100. The guide rail units of the guide rail structure located at the upper part of the tray 100 correspond one-to-one to the guide rail units of the guide rail structure located at the lower part of the tray 100. The two guide rail units corresponding to each other are called a set of guide rail belt units. Each set of guide rail belt units forms at least two rails of different widths, and the rails of different widths are respectively suitable for installing SSDs of different forms. The SSD is inserted into the storage space along its length direction, and the width direction ( Figure 1 The thickness direction of SSD is located between the upper and lower guide rail structures. Figure 1 The left and right directions. This allows the tray 100 equipped with the guide rail structure of the present application to simultaneously carry SSDs with both U.2 and E3.S standards. Therefore, when testing SSDs of these two standards, there is no need to replace the tray 100 and the guide rail structure, nor is there a need to prepare multiple versions of guide rail structures for SSDs of different standards. This greatly improves the ease of use of the test tool and reduces the complexity of test equipment maintenance.

[0047] like Figure 3 As shown, the guide rail unit of the guide rail structure located on the upper part of the tray 100 includes a plurality of guide rails in the width direction of the tray 100 ( Figure 1 The two grooves stacked in the vertical direction are respectively a first U2 groove 202 and a first E3S groove 201. The first U2 groove 202 and the first E3S groove 201 have different widths and depths.

[0048] like Figure 6 As shown, the guide rail unit of the guide rail structure located at the bottom of the tray 100 includes two grooves stacked in the width direction of the tray 100, namely the second E3S groove 301 and the second U2 groove 302. The second E3S groove 301 and the second U2 groove 302 have different widths and depths.

[0049] The upper guide rail assembly 8 includes multiple upper guide rail structures, and the lower guide rail assembly 9 includes a lower guide rail structure. A first track is formed between the first E3S groove 201 and the second E3S groove 301 of two opposing guide rail units in the upper and lower guide rail structures. A second track is formed between the first U2 groove 202 and the second U2 groove 302 of two opposing guide rail units in the upper and lower guide rail structures. The distance d1 between the first E3S groove 201 and the second E3S groove 301 of the two opposing guide rail units and the distance d2 between the first U2 groove 202 and the second U2 groove 302 of the two opposing guide rail units are of different sizes. The first track and the second track are respectively used to insert SSDs of different shapes.

[0050] like Figure 1 As shown, the first U2 groove 202, the second U2 groove 302 and the first E3S groove 201, the second E3S groove 301 are used to form a track for accommodating U.2 SSD and a track for E3.S SSD respectively. The first E3S groove 201 of the guide rail structure located at the upper part of the tray 100 and the second E3S groove 301 of the guide rail structure located at the lower part of the tray 100 are arranged opposite to each other, and a storage space for accommodating SSD is formed between the first E3S groove 201 and the second E3S groove 301, and a storage space for accommodating SSD is formed between the first U2 groove 202 and the second U2 groove 302. Therefore, the width of the first U2 groove 202 and the second U2 groove 302 (in Figure 1 The size of the left and right directions (slightly larger than 15mm) corresponds to the thickness of the U.2SSD to be accommodated, and the width of the first E3S groove 201 and the second E3S groove 301 (in Figure 1 The dimension in the left-right direction (slightly larger than 7.5mm) corresponds to the thickness of the E3.S SSD to be accommodated.

[0051] In order to improve the integration level or the number of SSDs accommodated in a unit space, the first U2 groove 202 and the first E3S groove 201 are overlapped in the left and right directions. For example, the first E3S groove 201 is located inside the first U2 groove 202. Figure 1In the vertical direction, the guide rail structure located above is the upper guide rail structure, and the guide rail structure located below is the lower guide rail structure. In the upper guide rail structure, the first E3S groove 201 is located above the first U2 groove 202. In the lower guide rail structure, the second E3S groove 301 is located below the second U2 groove 302. As a result, the distance between the two opposing guide rail units in the upper and lower guide rail structures is greater than the distance between the paired first E3S grooves 201 and second E3S grooves 301. The distance between the paired first E3S grooves 201 and second E3S grooves 301 (slightly greater than 76 mm) is designed to accommodate the width of an E3.S SSD, and the distance between the paired first U2 grooves 202 and second U2 grooves 302 (slightly greater than 69.85 mm) is designed to accommodate the width of a U.2 SSD.

[0052] Preferably, a plurality of accommodating spaces for inserting SSDs are formed between the guide rail structure located at the upper portion and the guide rail structure located at the lower portion of the tray 100 , thereby being suitable for batch testing of a plurality of SSDs to improve testing efficiency.

[0053] like Figure 1 As shown, the guide rail structure located at the top and bottom of the tray 100 has corresponding guide rail units 20. The paired guide rail units 20 overlap in the left-right direction, so that the pair of U2 grooves (first U2 groove 202 and second U2 groove 302) provided by the paired guide rail units 20 overlap in the left-right direction, and the pair of E3S grooves (first E3S groove 201 and second E3S groove 301) overlap in the left-right direction. The pair of U2 grooves (first U2 groove 202 and second U2 groove 302) together provide two tracks for accommodating a U.2 SSD, namely an upper track and a lower track. The upper and lower parts of the U.2 SSD are inserted into the guide rail structure along the upper and lower tracks, respectively, for inserting the U.2 SSD into the tray 100. A pair of E3S grooves (first E3S groove 201 and second E3S groove 301 ) together provide two tracks, namely an upper track and a lower track, for accommodating an E3.S SSD. The upper and lower parts of the E3.S SSD are respectively inserted into the guide rail structure along the upper track and the lower track for inserting the E3.S SSD into the tray 100 .

[0054] As a specific embodiment of the present invention, the tray 100 is connected to a backplane, which includes a plurality of connectors. Figure 1 The tray 100 is inserted in the direction of the cross section shown, so that the connector of the SSD is electrically connected to the connector of the backplane, thereby enabling testing of the SSD.

[0055] Optionally, the tray 100 may use a single guide rail structure to accommodate the SSD. The number of guide rail structures is not limited and those skilled in the art may independently configure them according to actual conditions.

[0056] like Figure 2 As shown, two guide rail structures are provided on the upper portion of the tray 100, and the two guide rail structures constitute a first group of guide rail structures, and the two guide rail structures are fastened together with the upper sheet metal structure 3 by screws 4. The upper sheet metal structure 3 is used to fix the guide rail structure on the tray 100.

[0057] Figure 3 In the figure, the first E3S groove 201 is below the first U2 groove 202. It can be understood that after the guide rail structure is installed in the tray 100, the first E3S groove 201 will be above the first U2 groove 202 because the guide rail unit 20 is flipped.

[0058] As a specific embodiment of the present invention, two adjacent guide rail structures among the multiple guide rail structures located on the upper portion of the tray 100 are arranged side by side, and multiple guide rail units 20 of a single guide rail structure are arranged side by side. Figure 2 The figure also shows the gaps between two adjacent guide rail structures 200. These gaps provide clearance between the SSDs housed in the adjacent guide rail structures 200. These gaps facilitate the flow of cooling air through the SSDs and improve heat dissipation. The gaps also facilitate the installation of screws, screw holes, and other fixing structures between adjacent guide rail structures 200 for securing or mounting the guide rail structures to the sheet metal structure.

[0059] Figure 4 The upper sheet metal structure 3 is shown. It is used to mount the guide rail structure located above the tray 100, thereby enabling modularization of the upper guide rail structure. For example, the guide rail structure located above the tray 100 can be shorter than the upper sheet metal structure 3, allowing for multiple upper guide rail structures to be mounted on the upper sheet metal structure 3. The upper sheet metal structure 3 includes screw holes, into which fasteners (e.g., screws) are mounted to securely connect the upper guide rail structure to the upper sheet metal structure 3.

[0060] like Figure 2 、 9 As shown, the upper guide rail assembly 8 includes a first upper guide rail structure 1 and a second upper guide rail structure 2. The first upper guide rail structure 1 and the second upper guide rail structure 2 are arranged along the length direction of the pallet 100. The first upper guide rail structure 1 and the second upper guide rail structure 2 are installed on the pallet 100 through the upper sheet metal structure 3.

[0061] As a specific embodiment of the present invention, the upper sheet metal structure 3 is further used to be fixed to the U-shaped support structure 10 , thereby fixing the first upper guide rail structure 1 and the second upper guide rail structure 2 to the U-shaped support structure 10 .

[0062] As a specific embodiment of the present invention, the lower guide rail structure is similar to the upper guide rail structure, and also consists of two guide rail structures.

[0063] like Figure 5 and 6 As shown, the lower guide rail assembly 9 includes a first lower guide rail structure 5 and a second lower guide rail structure 6. The first lower guide rail structure 5 and the second lower guide rail structure 6 are respectively fixedly connected to the sheet metal structure. Specifically, the first lower guide rail structure 5 and the second lower guide rail structure 6 are fastened together with the sheet metal structure by screws 4.

[0064] like Figure 6 As shown, the first lower guide rail structure 5 and the second lower guide rail structure 6 are both provided with a second U2 groove 302 and a second E3S groove 301 , so that a U.2 SSD can be inserted into the second U2 groove 302 and an E3.SSSD can be inserted into the second E3S groove 301 .

[0065] As a specific embodiment of the present invention, the first lower guide rail structure 5 and the second lower guide rail structure 6 both include multiple guide rail units 20, the first lower guide rail structure 5 includes multiple second U2 grooves 302 and second E3S grooves 301; the second lower guide rail structure 6 includes multiple second U2 grooves 302 and second E3S grooves 301.

[0066] like Figure 7 As shown, a region between two adjacent guide rail structures 200 is hollowed out to form a cavity 203. The cavity 203 is used to assist ventilation, thereby providing ventilation and heat dissipation for the SSD mounted on the guide rail structure 200 and reducing weight.

[0067] like Figure 8 The figure shows a schematic diagram of the lower sheet metal structure 7. The lower sheet metal structure 7 is used to mount the lower guide rail structure, thereby allowing the lower guide rail structure to be modularized. For example, the lower guide rail structure can be shorter than the lower sheet metal structure 7, and multiple lower guide rail structures (e.g., a first lower guide rail structure 5 and a second lower guide rail structure 6) can be mounted on the lower sheet metal structure 7. The lower sheet metal structure 7 includes screw holes for securing the lower guide rail structure to the lower sheet metal structure 7.

[0068] As a specific embodiment of the present invention, the lower sheet metal structure 7 is further used to be fixed to the U-shaped support structure 10 , thereby fixing the first lower guide rail structure 5 and the second lower guide rail structure 6 to the U-shaped support structure 10 .

[0069] As a specific embodiment of the present invention, the lower sheet metal structure 7 is provided with a plurality of openings, which correspond to the gaps between the adjacent guide rail units of the lower guide rail structure, so that air can flow through the openings to enhance the heat dissipation of the SSD.

[0070] Example 3

[0071] like Figure 9 As shown, a guide rail structure supporting various types of SSDs includes: a supporting structure, an upper guide rail assembly 8, and a lower guide rail assembly 9. The upper guide rail assembly 8 and the lower guide rail assembly 9 are mounted on the supporting structure.

[0072] Preferably, the supporting structure is a U-shaped supporting structure 10 .

[0073] like Figure 10 As shown, a back plate 12 is mounted on the back side of the U-shaped supporting structure 10 .

[0074] As a specific embodiment of the present invention, backplane 12 includes multiple connectors for electrically connecting to each SSD inserted into tray 100. Each SSD plugs into a connector on backplane 12. The connector complies with the SFF8639 standard and is designed to directly connect to a U.2 SSD. Backplane 12 also includes other components, such as cables, for connecting the connector to a cable or other interface, and then to an external computer. Backplane 12 is assembled to U-shaped support structure 10 using screws 4.

[0075] As a specific embodiment of the present invention, there is no need to worry about mis-insertion or mixing of SSDs of different standards when inserting them into the tray 100 of the present application. The U2 groove 202 can only accommodate U.2 SSDs, and the E3S groove 201 can only accommodate E3.S SSDs. Since the width of the E3S groove 201 is smaller than the thickness of the U.2 SSD, the U.2 SSD cannot be inserted into the E3S groove 201. Optionally, the distance between the U2 grooves 202 of the upper and lower guide rail units 200 is smaller than the width of the E3.S SSD, so that if the E3.SSSD is not inserted into the E3S groove 201, it cannot enter between the U2 grooves 202 of the upper and lower guide rail units 200, making it impossible for the E3.S SSD to be inserted into the U2 groove 202.

[0076] As a specific embodiment of the present invention, the connector on the backplane 12 is suitable for inserting a U.2 SSD, but not for inserting an E3.S SSD, because they have interface connectors of different standards.

[0077] like Figure 11 and 12As shown, it is a schematic diagram of the adapter plate 204, which has a top surface and a bottom surface, and the top surface and the bottom surface of the adapter plate are respectively provided with connectors for inserting different forms of SSDs; the connectors on the top surface of the adapter plate and the connectors on the bottom surface are one-to-one electrically connected. The side marked TOP (i.e. the top surface) is provided with a plurality of connectors suitable for connecting E3.S SSDs (for example, in accordance with the SFF-TA-1002 standard), and the side marked Bottom (i.e. the bottom surface) is provided with a plurality of connectors suitable for connecting U.2 SSDs (for example, in accordance with the SFF8639 standard). The connectors on the Top surface and the Bottom surface are one-to-one electrically connected.

[0078] When it is necessary to test E3.S SSDs, the adapter plate 204 is installed on the backplane 12 so that the connectors on the Bottom surface of the adapter plate 204 are connected to the connectors on the backplane 12, and the connectors on the Top surface of the adapter plate 204 are used to insert E3.S SSDs. By inserting E3.S SSDs into the adapter plate 204, the electrical connection between the SSDs and the backplane 12 is achieved, thereby achieving the test of E3.S.

[0079] Optionally, the adapter plate 204 is also fixed on the backplane 12, or fixed on the U-shaped support structure 10.

[0080] As Figure 13 shown, it is a schematic diagram of the guide rail device with the U.2 to E3.S adapter plate 16 installed. The U.2 to E3.S adapter plate 16 is installed on the sheet metal fixing member 15, and the E3.S SSD 17 is installed on the U.2 to E3.S adapter plate 16.

[0081] As Figure 11 shown, the Top surface of the adapter plate 204 includes four connectors, and four E3.S SSDs can be inserted.

[0082] Optionally, a plurality of adapter plates 204 can be installed on the backplane 12. In the optional scheme, the connectors on the backplane 12 are connectors suitable for E3.S SSDs, and the adapter plate 204 provides connectors suitable for U.2 SSDs.

[0083] As a specific embodiment of the present invention, the connector of the backplane 12 is suitable for inserting a U.2 SSD, which is relatively better. Because the width of the E3.S SSD is larger, the sheet metal fixing 15 will occupy part of the space when the adapter plate 204 is used. In the presence of the sheet metal fixing 15, the U.2 SSD can still be inserted into the backplane 12 without being blocked. Therefore, regardless of whether the E3.S SSD is connected or not, the sheet metal fixing 15 can remain on the tray 100 without having to be removed. At this time, both the U.2 SSD and the E3.S SSD can be inserted into the backplane 12. If the connector of the backplane 12 is a connector suitable for the E3.S SSD, when the sheet metal fixing 15 is present, the E3.S SSD will be blocked by the sheet metal fixing 15, causing an obstacle when inserting it into the backplane 12.

[0084] It is understood that the sheet metal fastener 15 is not necessary. The sheet metal fastener 15 is used to strengthen the fixation between the adapter plate 204 and the back plate 12, and the distance between the sheet metal fastener 15 and the back plate 12 is substantially equivalent to the height of the connector on the back plate 12.

[0085] Example 4

[0086] like Figure 14 FIG. 1 is a schematic diagram of the first test equipment assembly structure. A U.2 SSD is inserted into the tray 100 through the upper and lower guide rail structures to form a test equipment assembly 13. The SSD can then be tested.

[0087] like Figure 14 In the test device assembly, only the U.2 SSD 14 is inserted, while the E3.S SSD 17 is not inserted, and the adapter board 204 is not installed.

[0088] Example 5

[0089] like Figure 15 The figure shows a schematic diagram of the second test equipment assembly. This assembly includes both E3.S and U.2 SSDs, allowing for simultaneous testing of multiple SSDs. A U.2 SSD 14 is inserted on the left side, while a U.2 to E3.S adapter board 16 is installed on the right side and an E3.S SSD 17 is inserted.

[0090] Figure 15 One adapter board is installed in the backplane, onto which four E3.S SSDs 17 can be inserted. Optionally, additional U.2 to E3.S adapter boards 16 can be installed on this board to accommodate more E3.S SSDs 17. The U.2 to E3.S adapter boards 16 cover all connectors on the backplane 12, allowing all slots to accommodate E3.S SSDs 17. Flexible configuration is possible based on production needs.

[0091] The beneficial effects achieved by this application are as follows:

[0092] (1) The test disk of this application is convenient and can quickly realize the fast plug-in and pull-out test of U.2 and E3.S SSD products.
