In the related art, in order to ensure stable signal transmission between the first connector and the second connector, the first connector is generally manually bent to make the first connector inclined relative to the second connector, and then signal testing is performed. In the related art, the angle between the second connector and the first connector is not easy to control, and the testing accuracy is insufficient. CONTENT OF THE UTILITY MODEL

The connector after adjustment and the test tool are placed in a whole machine server for testing, which eliminates uncertain factors of manual inclination. Not only can the connection reliability of the connector itself be quickly detected, such as whether there is a signal or an influence on the signal strength, but also the performance of the whole machine server and the signal stability of the connector in the inclined state can be tested. The operation is simple, the cost is low, the applicability is wide, and the test result is more accurate.

[0007] In some embodiments, the adjusting device comprises a screw rod, an abutting column and a sleeve, the limiting device is provided with a mounting hole, the sleeve is arranged in the mounting hole, the abutting column is slidably arranged in the sleeve, an inner thread is arranged on the inner wall of the sleeve, the screw rod is connected with the inner thread, and the screw rod is used to abut against the abutting column, so that the abutting column extends out of the mounting hole and abuts against the fixing plate.

[0008] By rotating the screw rod, the screw rod is abutted against the abutment post to extend out of the sleeve and abut against the fixed plate, the sleeve moves away from the fixed plate, the overall length of the adjusting device changes, the limiting device is deflected, and the first connector is deflected relative to the second connector and can be kept in the deflected state.

[0009] In some embodiments, the adjusting device further comprises an elastic member, the elastic member is arranged in the sleeve, and the elastic member is located between the abutment post and the screw rod.

[0011] In some embodiments, one end of the abutment post is provided with a first stopper, the first stopper is located in the sleeve, and the end of the sleeve is provided with a second stopper for abutting against the first stopper to prevent the first stopper from extending out of the sleeve.

[0012] The arrangement of the stopper can limit the stroke of the abutment post, prevent the screw rod from rotating too much, and prevent the abutment from causing too much pressure. When the elastic member is not arranged, the damage of the first connector and the second connector caused by the excessive stroke of the abutment can be avoided, and when the elastic member is arranged, the failure of the elastic member caused by excessive pressure can also be avoided.

[0013] In some embodiments, a scale line is arranged on the abutment post, and the scale line is arranged along the center line direction of the abutment post.

[0014] By changing the position of the lowermost edge of the sleeve on the scale line of the abutment post, the inclination angle of the limiting block can be calculated, the quantitative adjustment of the inclination angle can be realized, and the influence of the deflection of the first connector and the second connector on the performance of the whole server can be quantified.

[0015] In some embodiments, the adjusting device comprises a first adjusting device and a second adjusting device, the first adjusting device and the second adjusting device are arranged at intervals along a first direction, and the first direction is perpendicular to the plug-in direction of the connector.

[0016] By arranging one adjusting device at each end of the length direction of the limiting device, the influence of the deflection on the performance of the whole server can be tested at both ends of the length direction of the connector.

[0017] In some embodiments, the adjusting device further comprises a third adjusting device, the third adjusting device is located between the first adjusting device and the second adjusting device, and the third adjusting device is spaced apart from the connecting lines of the first adjusting device and the second adjusting device.

[0018] Through the above arrangement, not only the length direction deflection test requirement of the connector can be met, but also the width direction deflection test requirement of the connector can be met, and the test requirement of the width direction and the length direction deflection can be met at the same time, which is beneficial to test more complex situations.

[0019] In some embodiments, the limiting device comprises a limiting block and a locking device, the limiting block is provided with a limiting channel, the limiting channel is used to pass through the first connector, the locking device is connected with the limiting block, and the locking device is used to lock the first connector to prevent the first connector from moving relative to the limiting block.

[0020] By dividing the limiting device into a limiting block and a locking device that can be detachably connected, the locking device can prevent the first connector from being separated from the limiting device during the adjustment of the adjusting device, and the adjusting device can be adjusted.

[0021] In some embodiments, the limiting channel is provided with an opening, the locking device comprises a locking plate, the locking plate is detachably connected with the limiting block, the locking plate covers at least part of the opening, and the locking plate is used to abut against the first connector at the opening.

[0022] The limiting block can limit the first connector from three directions in the horizontal direction, and the locking plate can limit the first connector in the last direction of the limiting device in the horizontal direction. Through the above arrangement, the horizontal direction has been completely limited. Since the locking plate can generate a large locking force, the first connector and the limiting block can be tightly locked, which facilitates the subsequent adjustment of the adjusting device to the limiting device.

[0023] In some embodiments, the locking plate comprises a first locking plate and a second locking plate, and the first locking plate and the second locking plate are spaced apart in the vertical direction of the connector insertion direction.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the application will be described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application.

[0037] Hereinafter, the terms "first", "second", and the like are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0038] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left", "right", "horizontal" and "vertical" are defined with respect to the orientation of the components shown in the drawings. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0039] In the embodiments of the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be fixed connection, electrical connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0040] Servers are generally used in large enterprises, data centers, and cloud computing fields, and servers have various types, common servers include computing servers, storage servers, and AI servers, etc., different types of servers have their specific application scenarios, but servers generally have connectors for signal transmission, connectors are mainly used for data transmission between chips and external devices, connectors include male and female heads, the male head generally has a protruding insertion part, and the female head generally has a recessed slot, the male head and the female head are inserted with each other, and the connector has a conductor inside for transmitting signals, so that the male head and the female head are inserted to complete signal transmission, common connector types include high-speed connectors, high-density connectors, MCIO connectors, etc. It should be noted that the connector can also be applied to other scenes, such as the connection between cables.

[0041] The performance of the server is not only related to the performance of the internal components themselves, but also inseparable from the connection reliability of the connector, so it is necessary to test the connection reliability of the connector, in the connector testing link of the server, the common way is for the operator to manually bend one of the male head and the female head inserted with each other, so that the male head and the female head are skewed, in order to observe the influence of the skew state on the data transmission of the connector, but it is difficult to accurately judge the degree of skew of the male head and the female head by manually bending, there is a large error, and the male head and the female head cannot be kept in the skewed state for a long time, therefore, it can only be determined whether the male head and the female head are connected or the strength of the signal in the skewed state, that is, only component-level testing can be achieved.

[0042] The ideal test scene is that the male head and female head in stable skew state are put into the whole machine server, so that the performance of the whole machine server in this state is monitored in a long time period, and further, the influence of the skew angle of the male head and the female head on the performance of the whole machine server is quantitatively detected by adjusting the skew angle of the male head and the female head.

[0043] To realize the above test requirement, the application provides a test tool, and the design idea is that the male head and the female head are first formed in a skew state, and then the skew state of the two is maintained, and the performance of the whole machine server is tested in the skew state of the two.

[0044] For the convenience of the following description, the connected male head is taken as the first connector 4000, and the connected female head is taken as the second connector 5000. Of course, in some embodiments, the first connector 4000 can also be a female head, and the second connector 5000 can be a male head, and the embodiments of the application do not limit this. Please refer to Figures 1-4 The application provides a test tool, which includes a limiting device 1000 and an adjusting device 2000. In order to facilitate replacement and reuse, the limiting device 1000 is detachably connected with the first connector 4000 of the connector on the fixing plate 3000. The first connector 4000 is inserted into the second connector 5000, and the second connector 5000 is connected to the fixing plate 3000. The fixing plate 3000 is a circuit board, which is provided with electronic components such as chips, power management elements, display devices and other electronic components or switches of other electrical equipment. The inside of the fixing plate 3000 also has a conductor electrically connected with the second connector 5000, so as to realize the connection of the second connector 5000 with other electrical equipment or power supply. The first connector 4000 can be connected with other electrical equipment or power supply through a wire.

[0045] Since the purpose of the test is to maintain a fixed skew angle a of the two connectors inserted into each other, please refer to Figure 4 , and the two connectors are placed in the whole machine server to test the performance of the whole machine server. Therefore, the first connector 4000 is fixed by using the limiting device 1000 in the embodiment, and the limiting device 1000 is also connected with an adjusting device 2000 which can adjust the height of one end of the limiting device 1000. The upper end of the adjusting device 2000 is fixed with the limiting device 1000, and the adjusting device 2000 abuts against the fixing plate 3000. When the length of the adjusting device 2000 changes, the height of one end of the limiting device 1000 changes, and the height of other positions does not change, so that the limiting device 1000 drives the first connector 4000 to skew relative to the second connector 5000 and can maintain the skew angle a.

[0046] The test tool provided by the embodiment of the application limits the first connector 4000 through the limiting device 1000, drives the limiting device 1000 to be skewed to one end through the adjusting device 2000, and keeps the skewed state between the first connector 4000 and the second connector 5000, so that the connector after adjustment and the test tool are placed in the whole server for testing, the uncertain factors of manual skewing operation are avoided, the connection reliability of the connector itself can be quickly detected, for example, whether there is a signal or an influence on the signal strength, and the performance of the whole server and the signal stability of the connector in the skewed state can be tested, the operation is simple, the cost is low, and the applicability is wide.

[0047] Please refer to Figure 5 In some embodiments, the adjusting device 2000 includes a screw rod 2100, an abutting column 2200 and a sleeve 2300, the screw rod 2100 and the abutting column 2200 are arranged in the sleeve 2300, the limiting device 1000 is provided with a mounting hole, the mounting hole is a through hole and is arranged at one end of the limiting device 1000, the sleeve 2300 is arranged in the mounting hole, the sleeve 2300 is fixedly connected with the limiting device 1000, and the fixed connection mode can adopt threaded connection or buckle connection, so that the adjusting device 2000 can drive the one end of the limiting device 1000 to move when the length of the adjusting device 2000 changes, the inner wall of the sleeve 2300 is provided with an internal thread, the screw rod 2100 is matched with the internal thread, the screw rod 2100 moves in the sleeve 2300 during the process of rotating the screw rod 2100, for example, the screw rod 2100 is screwed downward, the abutting column 2200 is slidably arranged in the sleeve 2300, the screw rod 2100 abuts against the abutting column 2200, the abutting column 2200 is given a downward force, the abutting column 2200 moves downward relative to the sleeve 2300, so that the abutting column 2200 extends out of the mounting hole and abuts against the fixed plate 3000, since the abutting column 2200 is blocked by the fixed plate 3000, it is equivalent to that the sleeve 2300 moves upward relative to the fixed plate 3000, the sleeve 2300 drives part of the limiting device 1000 to move upward, and the other part of the limiting device 1000 does not change in height, so that the skewed state is formed.

[0048] The screw rod 2100 abuts against the abutting column 2200 and extends out of the sleeve 2300 and abuts against the fixed plate 3000 by rotating the screw rod 2100, the sleeve 2300 moves away from the fixed plate 3000, so that the overall length of the adjusting device 2000 changes, the limiting device 1000 is skewed, and the first connector 4000 is skewed relative to the second connector 5000 and can keep the skewed state.

[0049] In some embodiments, the adjusting device 2000 further comprises an elastic member 2400, which is arranged in the sleeve 2300 and between the abutting column 2200 and the screw rod 2100. The lower end of the screw rod 2100 abuts against the elastic member 2400. During the screwing process of the screw rod 2100, the elastic member 2400 is compressed. The elastic member 2400 can be a spring or other elastic element. For example, a block-shaped element made of elastic material can be arranged between the screw rod 2100 and the abutting column 2200 to achieve the above function.

[0050] The arrangement of the elastic member 2400 has a good protection mechanism. The maximum elastic force that the elastic member 2400 can withstand is set to be less than the stroke of the screw rod 2100 when the first connector 4000 and the second connector 5000 are damaged. It can be ensured that when the screw rod 2100 cannot be screwed, the first connector 4000 and the second connector 5000 have not been damaged. Otherwise, continuously screwing the screw rod 2100 will cause the inclination angle a of the first connector 4000 and the second connector 5000 to be too large, resulting in damage to the first connector 4000 and the second connector 5000.

[0051] Please refer to Figures 5-6 In some embodiments, one end of the abutting column 2200 is provided with a first stopper 2210. The first stopper 2210 is arranged at the upper end of the abutting column 2200. The first stopper 2210 has a stepped surface. The first stopper 2210 is arranged in the sleeve 2300. The end of the sleeve 2300 is provided with a second stopper 2310. The second stopper 2310 also has a stepped surface. The stepped surface of the second stopper 2310 is used to abut against the stepped surface of the first stopper 2210 to prevent the first stopper 2210 from extending out of the sleeve 2300.

[0052] The arrangement of the stopper can limit the stroke of the abutting column 2200, prevent the screw rod 2100 from rotating too much, and cause excessive pressure on the abutting column 2200. When the elastic member 2400 is not arranged, the excessive stroke of the abutting column 2200 can be avoided to damage the first connector 4000 and the second connector 5000. When the elastic member 2400 is arranged, the excessive pressure on the elastic member 2400 can be avoided to cause failure of the elastic member 2400.

[0053] In some embodiments, the abutting column 2200 is provided with a scale line 2220. The scale line 2220 is arranged along the center line direction of the abutting column 2200. The inclination angle a of the limiting block 1100 can be calculated by changing the position of the lowermost edge of the sleeve 2300 on the scale line 2220 of the abutting column 2200. The quantitative adjustment of the inclination angle a can be achieved. The influence of the deflection of the first connector 4000 and the second connector 5000 on the performance of the whole server can be quantified.

[0054] Please refer to Figure 7In some embodiments, the adjusting device 2000 comprises a first adjusting device 2500 and a second adjusting device 2600, the first adjusting device 2500 and the second adjusting device 2600 are arranged at intervals along a first direction, the first direction is perpendicular to the plugging direction of the connector, in the present embodiment, the first direction is the length direction of the limiting device 1000, and the two adjusting devices 2000 can be arranged at two ends of the limiting device 1000.

[0055] By arranging one adjusting device 2000 at each end of the length direction of the limiting device 1000, the influence of the inclination degree on the performance of the whole server can be tested at both ends of the length direction of the connector.

[0056] Please refer to Figure 8 In some embodiments, the adjusting device 2000 further comprises a third adjusting device 2700, the third adjusting device 2700 is arranged between the first adjusting device 2500 and the second adjusting device 2600, and the third adjusting device 2700 is arranged at intervals with the connecting lines of the first adjusting device 2500 and the second adjusting device 2600, that is, one adjusting device 2000 is arranged at each end of the length direction of the limiting device 1000, and one adjusting device 2000 is arranged at one end of the width direction of the limiting device 1000.

[0057] Through the above arrangement, not only the test requirement of the inclination of the length direction of the connector can be met, but also the test requirement of the inclination of the width direction of the connector can be met, and the test requirement of the inclination of the width direction and the length direction at the same time can be met, which is beneficial to test more complex situations.

[0058] In some embodiments, one adjusting device 2000 is arranged at one side of the length direction of the limiting device 1000, and one adjusting device 2000 is arranged at one end of the width direction of the limiting device 1000, so that the inclination of the length direction and the width direction of the limiting device 1000 can be realized, if the inclination of the other side of the length direction and the width direction of the limiting device 1000 is required to be realized, the limiting device 1000 can be removed from the first connector 4000, then the limiting device 1000 is rotated by 180° in the horizontal direction, and then the limiting device 1000 is installed on the first connector 4000, so that the inclination of the other side of the length direction and the width direction of the limiting device 1000 can be realized.

[0059] Please refer to Figure 8In some embodiments, the limiting device 1000 comprises a limiting block 1100 and a locking device 1200, i.e. the limiting device 1000 is divided into two parts, which facilitates replacement and disassembly. The limiting block 1100 is provided with a limiting passage 1110, which is used to pass through the first connector 4000. The limiting passage 1110 can be sleeved on the first connector 4000 and is adapted to the outer dimensions of the first connector 4000. The locking device 1200 is connected with the limiting block 1100. The limiting block 1100 is passed through the cable on the upper end of the first connector 4000, and then is slid to a specified position on the first connector 4000. The limiting block 1100 is locked together with the first connector 4000 by the locking device 1200, so as to prevent the first connector 4000 from moving relative to the limiting block 1100.

[0060] By dividing the limiting device 1000 into the limiting block 1100 and the locking device 1200 which are detachably connected, the locking device 1200 can prevent the first connector 4000 from being separated from the limiting device 1000 during the adjustment of the adjusting device 2000, and can be adjusted.

[0061] In some embodiments, the locking device 1200 comprises a locking plate 1210, which is detachably connected with the limiting block 1100, such as being connected by a screw 1220. The locking plate 1210 is a cover plate, which is provided with a through hole. The limiting block 1100 is correspondingly provided with a threaded hole. The screw 1220 passes through the through hole on the locking plate 1210 and is screwed into the threaded hole on the limiting block 1100, so as to realize the connection between the limiting block 1100 and the locking plate 1210. The limiting passage 1110 is provided with an opening. The locking plate 1210 is arranged at the position of the opening and covers at least part of the opening. The locking plate 1210 is used to abut against the first connector 4000 at the opening, so as to prevent the first connector 4000 from being separated from the limiting block 1100 along the opening of the limiting block 1100 when the inclination angle a is adjusted. The limiting block 1100 and the locking plate 1210 can also be connected by other detachable connection modes, such as buckle connection, sliding connection of the locking plate 1210 on the limiting block 1100, etc.

[0062] The limiting block 1100 can limit the first connector 4000 from three directions in the horizontal direction. The locking plate 1210 can limit the first connector 4000 from the last direction in the horizontal direction of the limiting device 1000. Through the above arrangement, the horizontal direction has been completely limited. Since the locking plate 1210 can generate a large locking force, the first connector 4000 can be tightly locked with the limiting block 1100, which facilitates the subsequent adjustment of the adjusting device 2000 to the limiting device 1000.

[0063] Please refer to Figure 3In some embodiments, the limiting block 1100 may not have an opening. The size of the limiting channel 1110 of the limiting block 1100 is set to be slightly larger than the outer dimensions of the first connector 4000. The limiting block 1100 is sleeved on the first connector 4000. Threaded holes are provided on both sides of the limiting block 1100 in the width direction. Screws are screwed into the threaded holes and abut against the first connector 4000. This can also prevent the limiting block 1100 from detaching from the first connector 4000.

[0064] Please refer to Figure 3 In some embodiments, the locking plate 1210 includes a first locking plate 1211 and a second locking plate 1212, which are spaced apart along the vertical direction of the connector insertion direction. In this embodiment, the first locking plate 1211 and the second locking plate 1212 are respectively located on both sides of the length direction of the limiting block 1100.

[0065] Using two locking plates allows for a more balanced force distribution on both sides of the first connector 4000, thereby enabling the limiting device 1000 to better fix the first connector 4000.

[0066] Please refer to Figure 3 In some embodiments, a limiting protrusion 1300 is provided on the side wall of the limiting channel 1110. The limiting protrusion 1300 extends inward from the upper surface of the limiting block 1100 and is used to abut against the end of the first connector 4000 away from the second connector 5000, that is, against the upper surface of the first connector 4000.

[0067] Therefore, the limiting protrusion 1300 can further limit the first connector 4000 in the height direction of the limiting device 1000, preventing the first connector 4000 from separating from the limiting block 1100, thereby achieving a better limiting effect.

[0068] It is worth noting that the function of the limiting block 1100 is to limit the first connector 4000. Its shape can be appropriately adjusted according to the external shape of the connector. The main body shape of the first connector 4000 is mostly rectangular, but in special cases, there may be irregular structures. If there are irregular structures on the first connector 4000, a corresponding avoidance structure can be set on the limiting block 1100. For example, if there is a notch or protrusion on the first connector 4000, a corresponding notch or protrusion can also be set on the limiting block 1100. As long as the limiting device 1000 can limit the first connector 4000, it is sufficient to facilitate the adjustment device 2000 to further adjust the limiting device 1000. Therefore, this application has wide applicability and does not need to specifically limit the type of connector.

[0069] The above merely illustrates the specific implementation of the embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
