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. During testing, due to factors such as installation and manufacturing errors, the positions of the server and the test head of the test module can easily deviate. Existing test modules struggle to effectively correct these positional deviations, potentially leading to server damage during testing. 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 testing module that can correct positional deviations between the server and the test head, reducing the risk of server damage during testing.
[0005] This utility model provides a server testing module, comprising: a mounting mechanism including a floating block, a connecting structure, a connector, and a first elastic element; the first elastic element connecting the floating block and the connecting structure; the connecting structure having a mounting hole with an annular protrusion on the inner wall of the mounting hole; the annular protrusion having a first conical surface facing away from the floating block; the connector including a rod and a head; one end of the rod connecting to the floating block, and the other end passing through the annular protrusion and connecting to the head; the head having a second conical surface; the inner side of the second conical surface connecting to the outer peripheral surface of the rod; and the outer side of the second conical surface having a rounded corner abutting against the first conical surface; the taper of the second conical surface being greater than the taper of the first conical surface; and a test head passing through the floating block and the connecting structure and mounted on the floating block, 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 creating mounting holes in the connecting structure and forming an annular protrusion on the inner wall of the mounting holes, the rod of the connector is connected to the floating block, and the head of the connector abuts against the first conical surface of the annular protrusion facing away from the floating block. This allows the rod of the connector to drive the floating block and the test head to move along the first conical surface, correcting the positional deviation between the server and the test head and reducing the risk of damage to the server during testing. Furthermore, a second conical surface is provided on the head, and the rounded corner formed on the outer side of the second conical surface abuts against the first conical surface, which can significantly reduce the frictional force of the rod sliding along the first conical surface. When there is a positional deviation, the floating block can more easily drive the test head to move along the first conical surface to absorb the error. After the test, the floating block can more easily reset under the elastic force of the first elastic element, allowing the test to proceed smoothly. In addition, setting the taper of the second conical surface to be greater than that of the first conical surface can ensure that the head always abuts against the first conical surface through the rounded corner during the correction of positional deviation, keeping the frictional force at a low value.
[0008] In one embodiment of this implementation, the floating block has an installation groove, the first elastic member is sleeved on the rod, one end of the first elastic member extends into the installation groove and abuts against the bottom wall of the installation groove, and the other end of the first elastic member abuts against the annular protrusion.
[0009] In one embodiment of this implementation, the bottom wall has a mating hole, the rod is threaded into the mating hole, and the outer peripheral surface of the rod has a boss that abuts against the bottom wall.
[0010] In one embodiment of this implementation, the annular protrusion surrounds and forms a movable hole, a portion of the rod is located in the movable hole and has a gap with the inner wall of the movable hole, and the ratio of the radius of the fillet to the gap is 10%-20%.
[0011] In one embodiment of this implementation, the plane passing through the axis of the connector is defined as the reference plane, and the angle between the second conical surface and the reference plane is less than 45°.
[0012] In one embodiment of this implementation, the mounting mechanism includes a mounting block, a guide post, and a second elastic element. The mounting block is used to mount on a machine base. The connecting structure is slidably connected to the mounting block via the guide post. The guide post is coaxially arranged with the connecting element. The second elastic element connects the connecting structure and the mounting block.
[0013] 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 disposed on the side of the first connecting block opposite to the floating block and is connected to the guide post.
[0014] In one embodiment of this implementation, the second connecting block has a first receiving groove, the mounting block has a second receiving groove, one end of the second elastic member is received in the first receiving groove, and the other end of the second elastic member is received in the second receiving groove; when the second connecting block and the mounting block slide relative to each other and approach each other to their limit positions, the second connecting block and the mounting block abut against each other, and the first elastic member is housed in the first receiving groove and the second receiving groove.
[0015] In one embodiment of this implementation, there are multiple connectors and guide posts, and they are arranged in a one-to-one correspondence.
[0016] In one embodiment of this implementation, the installation mechanism includes a guide sleeve, which is installed on the side of the floating block facing away from the connecting structure by a snap fastener, and the test head is installed on the guide sleeve.

[0034] Please see Figures 1 to 3 , 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 cross-sectional schematic diagram of the server test module 100 via connector 13;
[0035] Figure 3 yes Figure 2 An enlarged schematic diagram of area A. This utility model provides a server test module 100, which includes a mounting mechanism 10 and a test head 20. The mounting mechanism 10 includes a floating block 11, a connecting structure 12, a connector 13, and a first elastic member 14. The first elastic member 14 connects the floating block 11 and the connecting structure 12. The connecting structure 12 has a mounting hole 1201, and an annular protrusion 1202 is formed on the inner wall of the mounting hole 1201. The annular protrusion 1202 has a first conical surface 1203 facing away from the floating block 11. The connector 13 includes a rod portion 131 and a head 132. One end of the rod portion 131 is connected to the floating block 11, and the other end of the rod portion 131 passes through the annular protrusion 1202 and is connected to the head 132. The head 132 has a second conical surface 1321. The inner side of the second conical surface 1321 is connected to the outer peripheral surface of the rod 131, and the outer side of the second conical surface 1321 has a rounded corner 1322, which abuts against the first conical surface 1203. The taper of the second conical surface 1321 is greater than the taper of the first conical surface 1203. The test head 20 passes through the floating block 11 and the connecting structure 12, and is installed on the floating block 11. The test head 20 is used to connect to the server under test.
[0036] Specifically, one end of the test head 20 is used to connect to the server under test, and the other end of the test head 20 is used to connect to a signal cable to transmit the test signal to the server. The first elastic element 14 can be a spring, leaf spring, or other elastic device. There is a gap between the floating block 11 and the connecting structure 12, so that when the server inserts the test head 20, the floating block 11 can move closer to the connecting structure 12 and compress the first elastic element 14 to achieve a certain buffer. The server test module 100 can be used to test interfaces of various types on the server, such as SAS interface, SlimSAS interface, GENZ interface, and MCIO interface.
[0037] Understandably, when there is a positional deviation between the server and the test head 20, the floating block 11 will undergo a combination of translation and rotation relative to the connecting structure 12 under the action of the server. For example, in Figure 3 In the schematic diagram shown, when the server is positioned slightly above the test head 20, it exerts a clockwise torque and a rightward thrust on the floating block 11, causing the floating block 11 to simultaneously rotate clockwise and translate to the right, thus bringing it closer to the connecting structure 12. During this process, because the taper of the second conical surface 1321 is greater than that of the first conical surface 1203, it ensures that when the floating block 11 rotates relative to the connecting structure 12 or needs to be rotated and reset after testing, it maintains contact with the second conical surface 1321 via the rounded corner 1322 as much as possible, reducing friction during the reset and docking processes.
[0038] By opening a mounting hole 1201 in the connecting structure 12 and forming an annular protrusion 1202 on the inner wall of the mounting hole 1201, the rod portion 131 of the connector 13 is connected to the floating block 11, and the head 132 of the connector 13 abuts against the first conical surface 1203 of the annular protrusion 1202 facing away from the floating block 11, so that the rod portion 131 of the connector 13 can drive the floating block 11 and the test head 20 to move along the first conical surface 1203, so as to correct the positional deviation between the server and the test head 20 and reduce the risk of damage to the server during the test. Furthermore, a second conical surface 1321 is provided on the head 132, and the rounded corner 1 formed on the outer side of the second conical surface 1321 is utilized. The contact between the 322 and the first conical surface 1203 can effectively reduce the frictional force of the rod 131 sliding along the first conical surface 1203. When there is a positional deviation, the floating block 11 can more easily drive the test head 20 to move along the first conical surface 1203 to absorb the error. After the test is completed, the floating block 11 can more easily reset under the elastic force of the first elastic element 14, so that the test can be carried out smoothly. Furthermore, by setting the taper of the second conical surface 1321 to be greater than the taper of the first conical surface 1203, it can be ensured that during the correction of positional deviation, the head 132 always contacts the first conical surface 1203 through the rounded corner 1322, so that the frictional force is kept at a small value.
[0039] In one embodiment of this implementation, please refer to Figure 3 The floating block 11 has a mounting groove 111. A first elastic element 14 is sleeved on the rod portion 131. One end of the first elastic element 14 extends into the mounting groove 111 and abuts against the bottom wall 112 of the mounting groove 111. The other end of the first elastic element 14 abuts against the annular protrusion 1202. By sleeved on the rod portion 131 and having both ends abut against the bottom wall 112 of the mounting groove 111 and the annular protrusion 1202 respectively, the space occupied by the first elastic element 14 can be reduced.
[0040] In this embodiment, the diameter of the first elastic member 14 is between the diameter of the mounting hole 1201 and the inner diameter of the annular protrusion 1202, so that the first elastic member 14 can be stably positioned between the bottom wall 112 of the mounting groove 111 and the annular protrusion 1202. The first elastic member 14 will not interfere with the movement of the connector 13, thereby reducing the resistance to the movement of the floating block 11.
[0041] In this embodiment, the mounting hole 1201 has an opening 1204 facing the floating block 11, and the annular protrusion 1202 is spaced apart from the opening 1204 to form a mounting chamber 1206 opposite to the mounting groove 111. The end of the first elastic member 14 away from the bottom wall 112 is housed in the mounting chamber 1206. When the floating block 11 and the connecting structure 12 approach each other to their extreme positions, the floating block 11 and the connecting structure 12 are in contact, and the first elastic member 14 is housed in the mounting groove 111 and the mounting chamber 1206. This arrangement can increase the buffer stroke between the floating block 11 and the connecting structure 12, thereby improving the impact resistance.
[0042] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , Figure 4 yes Figure 2 A three-dimensional structural diagram of the connector 13 is shown. The bottom wall 112 has a mating hole 1121, and the rod portion 131 is threaded into the mating hole 1121. A boss 1311 is provided on the outer circumferential surface of the rod portion 131, and the boss 1311 abuts against the bottom wall 112. This arrangement allows the rod portion 131 to obtain support after threading into the mating hole 1121, through the abutment between the boss 1311 and the bottom wall 112, thus improving the installation accuracy of the connector 13.
[0043] In this embodiment, the boss 1311 extends along the axial direction of the rod 131 to form a ring. The ring-shaped boss 1311 fits against the bottom wall 112 to increase the support area and further improve the installation accuracy of the connector 13.
[0044] In one embodiment of this implementation, please refer to Figure 3The annular protrusion 1202 encloses and forms a movable hole 1205. A portion of the rod portion 131 is located in the movable hole 1205 and has a gap D with the inner wall of the movable hole 1205. The ratio of the radius R of the fillet 1322 to the gap D is 10%-20%. Specifically, the ratio of radius R to gap D can be selected as 10%, 13.5%, 14.5%, 16.7%, 18.6%, 20%, etc. Understandably, when the ratio of the radius R of the fillet 1322 to the gap D is less than 10%, the radius R of the fillet 1322 is too small, resulting in insufficient structural strength in the area corresponding to the fillet 1322. Frequent testing can easily damage the surface, leading to increased friction. Conversely, when the ratio is greater than 20%, the radius R of the fillet 1322 is too large, and the curvature of the fillet 1322 is too small. This can easily lead to the area outside the fillet 1322 contacting the first conical surface 1203, further increasing friction. By setting the ratio of the radius R of the fillet 1322 to the gap D to 10%-20%, sufficient structural strength in the area corresponding to the fillet 1322 is ensured, while the fillet 1322 can maintain contact with the first conical surface 1203 as much as possible, thus keeping the friction within a relatively small range.
[0045] In one embodiment of this implementation, please refer to Figure 3 The plane passing through the axis of connector 13 is defined as reference plane 91, and the angle α formed between the second conical surface 1321 and reference plane 91 is less than 45°. Specifically, the angle α formed between the second conical surface 1321 and reference plane 91 can be selected as 15°, 30°, or 45°. This setting ensures that the head 132 has sufficient structural strength to facilitate contact between the fillet 1322 and the second conical surface 1321.
[0046] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The mounting mechanism 10 includes a mounting block 15, a guide post 16, and a second elastic element 17. The mounting block 15 is used to mount the device on the machine. The connecting structure 12 is slidably connected to the mounting block 15 via the guide post 16. The guide post 16 and the connector 13 are coaxially arranged. The second elastic element 17 connects the connecting structure 12 and the mounting block 15. This arrangement allows the second elastic element 17 to absorb the impact force during server testing. Furthermore, the coaxial arrangement of the guide post 16 and the connector 13 reduces the module's dimensions in the x and y directions (i.e., the cross-sectional dimensions perpendicular to the guide post 16), which is beneficial for testing servers with compact interface layouts.
[0047] In one embodiment of this implementation, please refer to Figure 1 and Figure 2The connecting structure 12 includes a first connecting block 121 and a second connecting block 122. A mounting hole 1201 is formed in the first connecting block 121, and the second connecting block 122 is located on the side of the first connecting block 121 facing away from the floating block 11 and is connected to the guide post 16. This arrangement allows the guide post 16 and the connector 13 to be installed separately, which helps to reduce the assembly difficulty.
[0048] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 5 , Figure 5 yes Figure 1 This is a three-dimensional structural diagram of the server test module 100 when the second connecting block 122 and the mounting block 15 are in their extreme positions. The second connecting block 122 has a first receiving groove 1221, and the mounting block 15 has a second receiving groove 151. One end of the second elastic member 17 is received in the first receiving groove 1221, and the other end of the second elastic member 17 is received in the second receiving groove 151. When the second connecting block 122 and the mounting block 15 slide relative to each other and approach each other to their extreme positions, the second connecting block 122 and the mounting block 15 abut against each other, and the first elastic member 14 is housed in the first receiving groove 1221 and the second receiving groove 151. With this configuration, the second elastic member 17 is installed through the first receiving groove 1221 and the second receiving groove 151. The installation structure is simple, and it can provide space for the second elastic member 17 when the second connecting block 122 and the second mounting block 15 slide relative to each other to their extreme positions, so as to ensure that the second elastic member 17 does not affect the buffer distance of the second connecting block 122 and improve the buffer stroke.
[0049] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The number of connectors 13 and guide posts 16 is multiple, and they are arranged in a one-to-one correspondence. In this way, the floating block 11 and the first connecting block 121 can be floated by multiple connectors 13, which improves the connection strength between the floating block 11 and the first connecting block 121. The sliding connection between the second connecting block 122 and the mounting block 15 can be achieved by multiple guide posts 16, which improves the connection strength between the second connecting block 122 and the mounting block 15. At the same time, the space occupied by multiple connectors 13 and multiple guide posts 16 can be reduced to a large extent, ensuring that the module has a small size in the x and y directions.
[0050] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The mounting mechanism 10 includes a guide sleeve 18, which is mounted on the side of the floating block 11 facing away from the connecting structure 12 via a snap fastener 181. The test head 20 is mounted on the guide sleeve 18. This configuration allows the server interface to be guided by the guide sleeve 18, ensuring that the server interface is aligned with the test head 20.
[0051] Understandably, during the testing process, the server interface is first inserted into the guide sleeve 18. Due to the positional deviation, the interface will apply a push and / or torque to the guide sleeve 18, causing the guide sleeve 18 to drive the floating block 11 to translate and / or rotate relative to the first connecting block 121 and move closer to the first connecting block 121, thereby achieving floating correction of the positional deviation.
[0052] 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.
