Abstract
Description
Technical Field
[0001] This utility model relates to the field of server testing technology, and in particular to a server testing module. Background Technology
[0002] A server is a common device that provides services to other computers or devices. A server can respond to client requests and provide the required information or perform specific tasks, such as data storage, resource sharing, and application execution.
[0003] Servers typically have multiple interfaces, each requiring a corresponding test module for testing. Some servers are tested using a vertical test bench, where the server and test module are brought close together vertically, allowing the server's interface to mate with the test head on the test module to complete the test. In this testing scenario, a smaller test module is required. Existing technology typically includes a front mounting block, a rear mounting block, and a test head. The test head is mounted on the front mounting block and is used to test the server's interface. To reduce the risk of damage to the server, guide posts and springs are usually placed between the front and rear mounting blocks. The front mounting block slides relative to the rear mounting block via the guide posts, and the springs provide some cushioning during testing. However, an excessively small design reduces the engagement length of the guide posts, making the test module slide less smoothly, and also shortens the spring's cushioning stroke, resulting in poor cushioning. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a server test module that, while having a smaller size, can ensure the mating length of the guide pillars and the buffer stroke, making the test module move more smoothly and providing a stronger buffering effect.
[0005] This utility model provides a server testing module, comprising: a mounting structure including a mounting component, a mounting block, a guide post, and a first elastic element; the mounting component is slidably connected to the mounting block via the guide post; the first elastic element is independently and parallelly disposed outside the guide post; the mounting component has a first mounting groove; the mounting block has a second mounting groove; the first mounting groove accommodates one end of the first elastic element; and the second mounting groove accommodates the other end of the first elastic element; when the mounting component and the mounting block slide relative to each other and approach each other to their extreme positions, the mounting component and the mounting block abut against each other, and the first elastic element is housed within the first mounting groove and the second mounting groove; and a test head, passing through the mounting component and the mounting block and connected to the mounting component, the test head being used to connect to the server to be tested.
[0006] The server testing module provided by this utility model has at least the following beneficial effects:
[0007] By independently and parallelly setting the first elastic element outside the guide post, since the first elastic element and the guide post are separated, there is no need to open slots to accommodate the first elastic element at the position where the mounting component and the mounting block install the guide post. This allows the guide post to have a longer mating length, and the relative sliding of the mounting component and the mounting block is smoother. At the same time, the mounting component has a first mounting slot and the mounting block has a second mounting slot. When the mounting component and the mounting block slide relative to each other and approach each other to their limit positions, the mounting component and the mounting block abut against each other, and the first elastic element is housed in the first mounting slot and the second mounting slot. This ensures that the mounting component and the mounting block have a longer buffer stroke and improves the buffering effect.

The test head is connected to the floating block.
[0009] In one embodiment of this implementation, the first connector includes a first conical surface, the connecting structure has a mounting hole, the inner wall of the mounting hole has an annular protrusion, the surface of the annular protrusion facing away from the floating block is a second conical surface, the first connector passes through the annular protrusion, and the second conical surface contacts the first conical surface.
[0010] In one embodiment of this implementation, the mounting assembly includes a second elastic member, which is sleeved on the first connector and its two ends abut against the floating block and the annular protrusion, respectively. The second elastic member is in a compressed state so that the first conical surface abuts against the second conical surface.
[0011] In one embodiment of this implementation, the connection structure includes a first connecting block and a second connecting block. The mounting hole is formed in the first connecting block, and the second connecting block is connected to the side of the first connecting block facing away from the floating block. The second connecting block has a fixing hole coaxial with the mounting hole, and one end of the guide post is fixed in conjunction with the fixing hole.
[0012] In one embodiment of this implementation, the second connecting block is provided with a positioning protrusion that engages with the mounting hole.
[0013] In one embodiment of this implementation, the connection structure includes a second connector, the second connecting block has a receiving groove, one end of the second connector is received in the receiving groove and abuts against the bottom wall of the receiving groove, and the other end of the second connector passes through the second connecting block and is fixedly connected to the first connecting block.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0034] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0035] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0037] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0038] In existing technologies, springs in test modules are typically fitted around the outer circumference of guide posts to prevent them from detaching. Furthermore, spring holes are created at the guide post mounting positions on both the front and rear mounting blocks to accommodate one end of the spring. While this allows for proper spring mounting, the presence of spring holes shortens the mating length between the guide post and the front (or rear) mounting block. Since vertical server testing requires smaller test module dimensions, this can easily lead to excessively short mating lengths, resulting in poor relative sliding between the front and rear mounting blocks. Additionally, because the spring holes are located coaxially with the guide posts, their depth cannot be excessive to ensure structural strength. This prevents the spring from fully compressing during testing, resulting in a short buffer stroke for the front mounting block and poor buffering performance.
[0039] Please see Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of the server test module 100 before testing, according to one embodiment of this utility model. Figure 2 yes Figure 1 A three-dimensional structural diagram of the server test module 100 when the mounting components 11 and mounting block 12 are in their extreme positions; Figure 3 yes Figure 1 A schematic diagram of the cross-section of the server test module 100 after passing through the guide post 13; Figure 4 yes Figure 2A cross-sectional view of the server test module 100 passing through the guide post 13 is shown in this embodiment of the present invention. The server test module 100 includes a mounting structure 10 and a test head 20. The mounting structure 10 includes a mounting component 11, a mounting block 12, a guide post 13, and a first elastic member 14. The mounting component 11 is slidably connected to the mounting block 12 via the guide post 13. The first elastic member 14 is independently and parallelly disposed outside the guide post 13. The mounting component 11 has a first mounting groove 1101, and the mounting block 12 has a second mounting groove 1201. The first mounting groove 1101 accommodates one end of the first elastic member 14, and the second mounting groove 1201 accommodates the other end of the first elastic member 14. When the mounting component 11 and the mounting block 12 slide relative to each other and approach each other to their extreme positions, the mounting component 11 and the mounting block 12 abut against each other, and the first elastic member 14 is housed within the first mounting groove 1101 and the second mounting groove 1201. The test head 20 passes through the mounting component 11 and the mounting block 12 and is connected to the mounting component 11. The test head 20 is used to connect to the server to be tested.
[0040] Specifically, the mounting block 12 is used to mount on the vertical base. One end of the test head 20 passes through the mounting assembly 11 and is exposed outside the mounting assembly 11 for connection to the server under test. The other end of the test head 20 passes through the mounting block 12 and is exposed outside the mounting block 12 for connection to the cable transmitting the test signal. The test head 20 can be fixedly connected to the mounting assembly 11 by screws, pins, or other devices, so that during testing, the thrust of the server on the test head 20 can be transmitted to the mounting assembly 11. The mounting assembly 11 and the mounting block 12 slide relative to each other and move closer together through the guide post 13, compressing the first elastic element 14, thereby achieving a buffering effect. The extension direction of the guide post 13 is vertical, and the elastic deformation direction of the first elastic element 14 is vertical, which can better absorb the impact brought by the test.
[0041] By independently and parallelly arranging the first elastic element 14 outside the guide post 13, since the first elastic element 14 and the guide post 13 are separated, there is no need to open slots to accommodate the first elastic element 14 at the positions where the mounting assembly 11 and the mounting block 12 install the guide post 13. This allows the guide post 13 to have a longer mating length, and the relative sliding of the mounting assembly 11 and the mounting block 12 is smoother. At the same time, the mounting assembly 11 has a first mounting groove 1101, and the mounting block 12 has a second mounting groove 1201. When the mounting assembly 11 and the mounting block 12 slide relative to each other and approach each other to their limit positions, the mounting assembly 11 and the mounting block 12 abut against each other, and the first elastic element 14 is housed in the first mounting groove 1101 and the second mounting groove 1201. This ensures that the mounting assembly 11 and the mounting block 12 have a longer buffer stroke, thus improving the buffering effect.
[0042] In one embodiment of this implementation, please refer to Figure 3 The mounting assembly 11 includes a floating block 111, a connecting structure 112, and a first connector 113. One end of the first connector 113 is connected to the floating block 111, and the other end of the first connector 113 engages with the conical surface of the connecting structure 112, allowing the floating block 111 to move relative to the connecting structure 112 in a direction intersecting the guide post 13. The first connector 113 and the guide post 13 are coaxially arranged. A first mounting groove 1101 is formed on the side of the connecting structure 112 facing away from the floating block 111. The test head 20 is connected to the floating block 111. This configuration allows the floating block 111 and the connecting structure 112 to be connected via the first connector 113, enabling the test head 20 to gain freedom of movement along a plane perpendicular to the test direction via the floating block 111, thus effectively correcting the positional deviation between the server and the test head 20.
[0043] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 , Figure 5 yes Figure 3 An enlarged schematic diagram of region A is shown. The first connector 113 includes a first conical surface 1131. The connecting structure 112 has a mounting hole 1120. The inner wall of the mounting hole 1120 has an annular protrusion 1121. The surface of the annular protrusion 1121 facing away from the floating block 111 is a second conical surface 1122. The first connector 113 passes through the annular protrusion 1121, and the second conical surface 1122 contacts the first conical surface 1131. With this configuration, the annular protrusion 1121 can limit the first connector 113, thereby preventing the connecting structure 112 from detaching from the first connector 113. At the same time, the annular protrusion 1121 can also cooperate with the conical surface of the first connector 113 to absorb errors in multiple directions.
[0044] Specifically, the first conical surface 1131 and the second conical surface 1122 can be in point contact (i.e., the first conical surface 1131 and the second conical surface 1122 have different tapers), or the first conical surface 1131 and the second conical surface 1122 can be in surface contact (i.e., the first conical surface 1131 and the second conical surface 1122 have the same taper).
[0045] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 The mounting assembly 11 includes a second elastic element 114, which is sleeved on the first connector 113. Both ends of the second elastic element 114 abut against the floating block 111 and the annular protrusion 1121, respectively. The second elastic element 114 is in a compressed state, causing the first conical surface 1131 to abut against the second conical surface 1122. This arrangement allows the floating block 111 to be reset by the elastic force of the second elastic element 114 after testing, facilitating the next test.
[0046] In one embodiment of this implementation, please refer to Figure 3 The connecting structure 112 includes a first connecting block 1125 and a second connecting block 1126. A mounting hole 1120 is formed in the first connecting block 1125. The second connecting block 1126 is connected to the side of the first connecting block 1125 facing away from the floating block 111. The second connecting block 1126 has a fixing hole 1127 coaxial with the mounting hole 1120. One end of the guide post 13 is fixed in place with the fixing hole 1127. This arrangement, with the mounting hole 1120 for the first connecting member 113 and the fixing hole 1127 for the guide post 13 respectively located in the first connecting block 1125 and the second connecting block 1126, simplifies assembly.
[0047] Specifically, one end of the guide post 13 is threaded into the fixing hole 1127 to achieve a fixed connection.
[0048] In one embodiment of this implementation, please refer to Figure 3 The second connecting block 1126 is provided with a positioning protrusion 1128, which mates with the mounting hole 1120. By providing a positioning protrusion 1128 on the second connecting block 1126 that mates with the mounting hole 1120, the assembly difficulty can be reduced, and the relative positional accuracy of the first connecting block 1125 and the second connecting block 1126 can be improved, ensuring that the test head 20 can be better aligned with the server.
[0049] In one embodiment of this implementation, please refer to Figure 1 and Figure 6 , Figure 6 yes Figure 1 The diagram shows a cross-section of the server test module 100 passing through the second connector 1123. The connection structure 112 includes the second connector 1123. A second connecting block 1126 has a receiving groove 1124. One end of the second connector 1123 is received in the receiving groove 1124 and abuts against the bottom wall of the receiving groove 1124. The other end of the second connector 1123 passes through the second connecting block 1126 and is fixedly connected to the first connecting block 1125. This configuration allows the first connecting block 1125 and the second connecting block 1126 to be connected and fixed via the second connector 1123. Simultaneously, the receiving groove 1124 can accommodate the end of the second connector 1123, ensuring that the presence of the second connector 1123 does not affect the buffer stroke.
[0050] In one embodiment of this implementation, please refer to Figure 3 and Figure 4The mounting block 12 has a connecting guide hole 1202 and a locking hole 1203. The diameter of the locking hole 1203 is larger than the diameter of the guide hole 1202. The guide post 13 includes a sliding part 131 and a locking part 132 connected to each other. The sliding part 131 is slidably engaged with the guide hole 1202, and the locking part 132 is located in the locking hole 1203 to restrict the sliding part 131 from sliding toward the mounting assembly 11. With this configuration, the engagement of the locking part 132 and the locking hole 1203 can prevent the mounting assembly 11 from detaching from the mounting block 12 in the axial direction, thus affecting the safety of the test.
[0051] Specifically, a first transition cone surface is provided between the locking hole 1203 and the guide hole 1202, and a second transition cone surface is also provided between the locking part 132 and the sliding part 131. The first transition cone surface and the second transition cone surface can abut each other to fully absorb the collision generated by the first elastic member 14 during reset.
[0052] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 There are multiple guide posts 13 and first connectors 113, and they are all coaxially arranged in a one-to-one correspondence. This arrangement can improve the accuracy of the relative sliding and the connection strength of the mounting assembly 11 and the mounting block 12, so as to better cope with high-intensity tests.
[0053] In one embodiment of this implementation, please refer to Figure 1 The mounting assembly 11 includes a guide sleeve 115, which is disposed on the side of the mounting assembly 11 facing away from the mounting block 12. The test head 20 is mounted on the guide sleeve 115. Specifically, the guide sleeve 115 is used to guide the server interface so that the server interface can smoothly dock with the test head 20. In this embodiment, the guide sleeve 115 is mounted on the mounting assembly 11 by a snap-fit and a pin.
[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
