DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in combination with the drawings. However, the example implementation can be implemented in various forms, and should not be understood as being limited to the implementation described herein. In the drawings, the same reference signs represent the same or similar structures, so repeated description thereof will be omitted. The expressions of position and direction described in the utility model embodiments are described by taking the drawings as examples, but changes can also be made according to needs, and the changes made are all included in the protection scope of the utility model. The drawings of the utility model embodiments are only used to show the relative position relationship, and do not represent the real proportion.

[0028] It should be noted that specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond those explicitly described, and the present application is not limited to the embodiments described in the following description.

[0029] With the rapid development of big data, artificial intelligence and other technologies, users have higher and higher requirements for server performance and data transmission processing capacity of electronic components inside the server. At present, the data transmission of electronic components inside the server mostly depends on an electrical connector for realizing electrical connection between each electronic component. In the prior art, the electrical connector generally includes a conductive male end and a conductive female end, and the conductive male end is inserted into the conductive female end for realizing electrical connection of the two. In addition, a clamping hook structure is generally designed between the two for improving the electrical connection stability of the conductive male end and the conductive female end. However, in actual use, the connection reliability of the above clamping hook structure is poor, which makes it difficult for the conductive male end and the conductive female end to realize stable electrical connection.

[0030] Therefore, how to improve the mechanical connection reliability and electrical connection reliability of the conductive male end and the conductive female end of the connector has become a difficult problem to be solved by those skilled in the art.

[0031] Therefore, the fastening device provided by the present application is used for abutting against one side of the conductive male end away from the conductive female end along the plug-in direction of the conductive male end, and is used for clamping with the side wall of the conductive female end. For improving the mechanical connection reliability and electrical connection reliability of the conductive male end and the conductive female end of the connector. In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] It should be noted that the present application takes the MCIO connector as an example to describe the fastening device provided by the present application in detail. It can be understood that the fastening device provided by the present application can also be applied to the fastening of other types of connectors.

[0033] Reference Figure 1 , Figure 1 is a structural schematic view of the MCIO connector. The MCIO connector includes a male end 01 (cable end) and a female end 02 (board card terminal, which is used for fixed connection with a board card), part of the male end 01 is inserted into the female end 02 for realizing electrical connection of the male end 01 and the female end 02, as shown in Figure 2 , Figure 2A structure schematic diagram for showing the insertion of the male end 01 and the female end 02. Specifically, the male end 01 comprises a male end shell and a male end PIN, and part of the male end PIN is inserted into the male end shell and fixedly connected with the male end shell. The female end 02 comprises a female end shell and a female end PIN, and part of the female end PIN is inserted into the female end shell and fixedly connected with the female end shell. The male end PIN is electrically connected with the female end PIN. In actual use, due to the limited installation space, the insertion depth of the male end 01 and the female end 02 of the MCIO connector is shallower than that of the SLIMLINE connector, so the insertion reliability of the MCIO connector is relatively poor.

[0034] At present, the insertion reliability of the male end 01 and the female end 02 of the MCIO connector is improved by setting a clamping structure between the male end 01 and the female end 02, and the clamping structure 11 is located at the middle position of the connector. However, in the process of force being applied to the connector, the MCIO connector will tilt along the left and right positions. According to the actual test results, if the tilt gap of the MCIO connector along the left and right positions is too large, the mating PIN contact area of the male end 01 and the female end 02 of the MCIO connector will be reduced, and even the PIN will be separated or misaligned, which will result in poor electrical connection stability of the server and problems such as speed reduction and bandwidth reduction.

[0035] Reference is made to Figure 1 and Figure 3 , Figure 3 A structure schematic diagram of the fastening device provided by the utility model. The fastening device comprises a crimping part 1, a clamping part 2 and a connecting structure 3, wherein the crimping part 1 is oppositely arranged with the clamping part 2 along the insertion direction of the male end 01, and there is a gap between the crimping part 1 and the clamping part 2, as shown in Figure 4 , Figure 4 A schematic diagram for showing the fastening device for fastening the connector. The above gap is used for accommodating at least part of the male end 01 and part of the female end 02. That is, along the Z-axis direction as shown in Figure 3 , as shown in Figure 1 , the male end 01 comprises oppositely arranged top and bottom walls 011 and 012, and the bottom wall 012 of the male end 01 is inserted into the female end 02. Then the crimping part 1 is close to the top wall 011 of the male end 01 relative to the female end 02.

[0036] When the connecting structure 3 and the crimping part 1 are specifically arranged, the connecting structure 3 is arranged outside the side wall of the male end 01 and the side wall of the female end 02, and one end of the crimping part 1 is connected with the connecting structure 3. Along the insertion direction of the male end 01, the side of the crimping part 1 facing the clamping part 2 is used for abutting against the side of the male end 01 away from the female end 02. For example, the crimping part 1 can abut against the top wall 011 of the male end.

[0037] In addition, as shown in Figure 3 The clamping portion 2 is arranged on the connecting structure 3 and protrudes from the surface of the connecting structure 3. The clamping portion 2 is used for clamping the female end 02. Specifically, as shown in Figure 5 Figure 5 In order to show the structure of the female end 02 of the connector, the side wall of the female end 02 shell is provided with a first gap 021, the clamping portion 2 is inserted into the first gap 021, and the side wall of the clamping portion 2 close to the crimping portion 1 abuts against the top wall 011 close to the crimping portion 1 of the first gap 021 in the direction from the clamping portion 2 to the crimping portion 1, so as to realize the clamping of the clamping portion 2 and the female end 02. As shown in Figure 4 It can be understood that when the clamping portion 2 is clamped with the female end 02, the clamping portion 2 protrudes from the surface of the connecting structure 3 in the direction towards the female end 02.

[0038] It should be noted that the number of clamping portions 2 is not limited, and one or more clamping portions 2 can be arranged. When multiple clamping portions 2 are arranged, the side wall of the female end 02 shell is provided with multiple first gaps 021, and the multiple first gaps 021 correspond to the multiple clamping portions 2 one by one.

[0039] The fastening device provided by the utility model is arranged between the crimping portion 1 and the clamping portion 2. When the connector is connected with the fastening device, the male end 01 and the female end 02 of the connector are arranged in the gap between the crimping portion 1 and the clamping portion 2, and the side of the crimping portion 1 close to the clamping portion 2 is used for abutting against the side of the male end 01 away from the female end 02 in the inserting direction of the male end 01, and the clamping portion 2 is clamped with the female end 02. In order to limit the male end 01 in the inserting direction of the male end 01, the risk of the male end 01 tilting relative to the female end 02 and the risk of the male end 01 separating from the female end 02 are effectively reduced, and the mechanical connection reliability and the electrical connection reliability of the male end 01 and the female end 02 of the connector are improved.

[0040] It can be understood that the fastening device provided by the utility model only needs to be connected with the existing structure of the connector on the board card, and does not need to reserve a related structure on the board card to fix the fastening device, so that the layout space of the case and the board card can be effectively saved.

[0041] In a specific embodiment, as shown in Figure 6 Figure 6 In order to show a state in the mounting process of the fastening device and the connector, the connecting structure 3 can be arranged around the side wall of the male end 01, and part of the connecting structure 3 is used for abutting against the side wall of the male end 01. As shown in Figure 6 ​​As shown in the Y-axis direction, the inner side wall of the connecting structure 3 abuts against the side wall of the male end 01 to limit the male end 01 in the Y-axis direction, thereby effectively reducing the risk of the clamping portion 2 being separated from the female end 02 due to external force, which is beneficial to further improve the mechanical connection reliability and electrical connection reliability of the male end 01 and the female end 02 of the connector.

[0042] In the specific arrangement of the connecting structure 3, in an optional embodiment, as shown in the drawings, Figure 3 The connecting structure 3 includes a first bending structure 31 and a second bending structure 32 that are hingedly connected, and the first bending structure 31 and the second bending structure 32 are buckled to form an accommodation space for accommodating part of the male end 01 and part of the female end 02. That is, as shown in the drawings, Figure 4 Along the circumference of the male end 01, the first bending structure 31 and the second bending structure 32 surround the side wall of the male end 01. It is worth mentioning that the first bending structure 31 and the second bending structure 32 can be connected by a hinge or can be an integral structure. For example, when the first bending structure 31 and the second bending structure 32 are an integral structure, the integral structure can be a plastic part, and the thickness of the connection position of the two is less than the thickness of the rest of the integral structure, so as to meet the hinging requirement of the two while reducing the manufacturing cost.

[0043] In addition, when the fastening device is provided with a plurality of clamping portions 2, the plurality of clamping portions 2 can be arranged on the first bending structure 31 and the second bending structure 32. At the same time, one end of the compression portion 1 is connected to the first bending structure 31, and the other end is used to clamp the second bending structure 32. In this way, during the connection of the fastening device and the connector, the first bending structure 31 can be arranged outside the side wall of the male end 01 of the connector, and the clamping portion 2 arranged on the first bending structure 31 is clamped with the female end 02 of the connector. Then, the second bending structure 32 is buckled towards the first bending structure 31, so that after the clamping portion 2 arranged on the second bending structure 32 is clamped with the female end 02 of the connector, the compression portion 1 connected to the first bending structure 31 is clamped with the second bending structure 32, so as to realize the abutment of the compression portion 1 and the side of the male end 01 away from the female end 02 along the insertion direction of the male end 01, thereby improving the electrical connection reliability and mechanical connection reliability of the male end 01 and the female end 02 of the connector, and effectively improving the installation convenience of the fastening device and the connector.

[0044] It should be noted that the utility model does not limit the connecting mode of the crimping part 1 and the first bending structure 31. Exemplarily, one end of the crimping part 1 can be connected with the first bending structure 31 through a fastener. In addition, one end of the crimping part 1 and the first bending structure 31 can be hingedly connected, so as to further improve the installation convenience of the fastening device and the connector. Specifically, the crimping part 1 and the first bending structure 31 can be an integral structure, and the connecting mode of the first bending structure 31 and the second bending structure 32 can be referred to, which will not be described here.

[0045] When the first bending structure 31 is specifically arranged, in an optional embodiment, continuing to refer to Figure 2 , the first bending structure 31 comprises a first bending part 311, a second bending part 312 and a connecting part 313, the connecting part 313 is located between the first bending part 311 and the second bending part 312, and is connected with the first bending part 311 and the second bending part 312. Exemplarily, the first bending structure 31 can be an integral structure, and specifically, the first bending structure 31 can be a bent plate structure. One end of the crimping part 1 is connected with the connecting part 313, and the crimping part 1 and the connecting part 313 can also be an integral structure. It should be noted that the connecting mode of the crimping part 1 and the connecting part 313 can refer to the connecting mode of the first bending structure 31 and the second bending structure 32, which will not be described here.

[0046] In addition, when the clamping part 2 is specifically arranged, in the direction from the connecting part 313 to the second bending structure 32, a part of the clamping part 2 protrudes from the surface of the connecting part 313, so as to realize the clamping with the female end 02. It is worth mentioning that, when the clamping part 2 is clamped with the female end 02, along the Y-axis direction as Figure 6 indicated, the first bending part 311 and the second bending part 312 are separately arranged on the two sides of the shell of the male end 01, and the inner side wall of the first bending part 311 and the inner side wall of the second bending part 312 are both used for abutting against the side wall of the shell of the male end 01. This can be used for limiting the male end 01 along the Y-axis direction, so as to effectively reduce the risk that the clamping part 2 is separated from the female end 02 due to external force, which is beneficial to further improve the mechanical connection reliability and the electrical connection reliability of the male end 01 and the female end 02 of the connector.

[0047] The utility model provides a fastening device, through the first bending structure 31 is set to the form of above-mentioned bending part and connecting part 313, and the clamping part 2 protrudes 3111 connecting part 313, one end of the crimping part 1 is connected with the connecting part 313, the other end is clamped with the second bending structure 32, and the second bending part 312 is hingedly connected with the second bending structure 32, and the first bending part 311 is detachably connected with the second bending structure 32. This can meet the demand that the fastening device is used for fastening the connector, and simplify the first bending structure 31 at the same time.

[0048] In the specific setting of the second bending structure 32, in an alternative embodiment, continuing to refer to Figure 3 , the second bending structure 32 comprises a third bending part 321 and a fourth bending part 322, and the third bending part 321 and the fourth bending part 322 are fixedly connected, and the second bending part 312 of the first bending structure 31 is hingedly connected with the fourth bending part 322. It should be noted that the second bending structure 32 can be an integral structure of a plastic material, and specifically, the second bending structure 32 can be a bent plate structure, and the connection mode of the second bending part 312 and the fourth bending part 322 can refer to the connection mode of the first bending structure 31 and the second bending structure 32, which will not be described here.

[0049] In addition, one end of the crimping part 1 is connected with the connecting part 313, and the other end is used for clamping with the fourth bending part 322, and at the same time, along the direction from the fourth bending part 322 to the connecting part 313, the other part of the clamping part 2 protrudes from the surface of the fourth bending part 322, and the first bending part 311 and the third bending part 321 are detachably connected. In this way, the second bending structure 32 can be simplified while meeting the needs of the fastening device for fastening the connector.

[0050] It should be noted that the connection mode of the first bending part 311 and the third bending part 321 is not limited, and for example, the two can be connected by a fastener or clamped with each other. In an alternative embodiment, the first bending part 311 is provided with a protrusion 3111 in a direction away from the second bending part 312, and the third bending part 321 comprises a clamping hole 3211. When the third bending part 321 is a plate structure, the clamping hole 3211 penetrates the plate surface of the third bending part 321 in the thickness direction of the plate structure, and the clamping hole 3211 is arranged opposite to the protrusion 3111. The protrusion 3111 is used to be inserted into the clamping hole 3211, so as to realize the clamping requirement of the first bending part 311 and the third bending part 321, and simplify the first bending structure 31.

[0051] It is worth mentioning that the first bending part 311 and the protrusion 3111 are plastic parts, and the protrusion 3111 can be chamfered, which is beneficial to improve the clamping convenience of the protrusion 3111 and the clamping hole 3211.

[0052] In a specific embodiment, referring to Figure 7 , Figure 7 for display Figure 3The bottom view of the provided fastening device is shown, one end of the crimping part 1 is hinged with the first bending structure 31, for example, the first bending structure 31 can be a structure comprising the first bending part 311, the second bending part 312 and the connecting part 313, and one end of the crimping part 1 is hinged with the connecting part 313, and the free end of the crimping part 1 is provided with the clamping structure 11, so as to realize the clamping of the crimping part and the second bending structure, thereby effectively improving the installation convenience of the fastening device and the connector.

[0053] It should be noted that the specific structure of the crimping part 1 is not limited, and the crimping part 1 is exemplarily a plate structure, and along the insertion direction of the male end 01, the plate surface of the plate structure is attached to the side of the male end 01 away from the female end 02, which can effectively improve the crimping stability of the crimping part 1.

[0054] In addition, as shown in Figure 3 , the second bending structure 32 is provided with a groove 323, for example, the second bending structure 32 can be a structure comprising the third bending part 321 and the fourth bending part 322, the groove 323 is arranged on the side of the second bending structure 32 away from the first bending structure 31, and the slot of the groove 323 is arranged opposite to the clamping structure 11, and the slot is exemplarily towards the positive direction of the Z axis. It can be understood that the groove 323 is arranged on the side of the fourth bending part 322 away from the connecting part 313 of the first bending structure 31. And as shown in Figure 4 , when the fastening device is used to fasten the connector, the clamping structure 11 is used to be inserted into the groove 323, and the clamping structure 11 is clamped with the side wall of the groove 323, which can improve the abutting stability of the crimping part 1 and the male end 01, and also improve the installation convenience between the fastening device and the connector. In addition, the fastening device can also realize tool-free installation, thereby facilitating the convenience of disassembly and later maintenance.

[0055] It is worth mentioning that along the Y axis direction as shown in Figure 4 , the fastening device can comprise two crimping parts 1, and the interval distance of the two crimping parts 1 is L, and L satisfies 23mm≤L≤28mm. It is beneficial to further reduce the risk of inclination between the side wall of the male end 01 of the connector and the side wall of the female end 02, thereby further improving the mechanical connection and electrical connection reliability of the male end 01 and the female end 02 of the connector.
