Description

Technical Field

[0001] This application relates to the field of connector testing technology, specifically a testing device for computer connectors. Background Technology

[0002] Connectors, also known as plugs or sockets, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, when in contact, can transmit information or current; hence, they are called connectors.

[0003] Chinese utility model patent CN22158014256U discloses a testing device for computer connectors. It uses a slider that is pierced by a limiting rod and a lead screw. A hydraulic cylinder is fixedly connected to the side of the slider away from the limiting rod, and a hydraulic rod is fixedly connected to the bottom of the hydraulic cylinder. A testing device is fixedly connected to the end of the hydraulic rod away from the hydraulic cylinder, and the testing device is located directly above the connector. The connector is located below the testing device, which facilitates more stable clamping of the connector by the clamping device, improving the safety of the device and reducing material consumption. A second motor drives the lead screw to rotate, causing the slider to move on the lead screw and the limiting rod. The slider drives the hydraulic cylinder to move on the lead screw, calibrating the position of the testing device above the connector. The lead screw facilitates adjustment of the testing device's position above the connector, enabling the testing device to perform insertion and removal tests on the connector. However, due to the lack of effective limitation on the stroke of the hydraulic cylinder, the output end of the hydraulic cylinder (such as the detection device driven by the hydraulic rod) is prone to excessive impact on the connector during the insertion and removal process; this can easily lead to connector damage. Excessive impact can cause problems such as connector interface deformation and internal contact wear, which not only affects the accuracy of the test results, but also increases the cost of connector wear and reduces the testing efficiency.

[0004] Therefore, this application provides a testing device for computer connectors to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a testing device for computer connectors, which aims to solve the problems mentioned in the background art, such as the lack of limitation on the stroke of hydraulic cylinders, which easily leads to damage to connectors due to excessive impact.

[0006] To achieve the above objectives, this application provides the following technical solution: a testing device for computer connectors, comprising a base, a bracket mounted on the base, a fixed clamp mounted on the base, a movable clamp mounted above the fixed clamp, and a hydraulic cylinder mounted on the top of the bracket for driving the movable clamp to move closer to or away from the fixed clamp. A counter is electrically connected to the hydraulic cylinder, and a controller electrically connected to the hydraulic cylinder and the counter is mounted on the base. A limit switch is mounted above the base to limit the extension length of the hydraulic cylinder's output end, and the installation height of the limit switch is higher than the sum of the heights of the fixed clamp and the movable clamp. An indicator plate adapted to the limit switch is fixedly connected to the output end of the hydraulic cylinder. An adjustment mechanism is mounted on the base to drive the limit switch to move closer to or away from the base. Through the cooperation of the indicator plate and the limit switch, the extension length of the hydraulic cylinder's output end can be precisely limited, effectively preventing collisions between the movable clamp and the fixed clamp, significantly improving safety during the testing process, preventing clamp damage and connector damage caused by collisions, reducing equipment maintenance costs and testing errors, and ensuring stable and reliable testing operations.

[0007] Preferably, the adjusting mechanism includes a guide rail fixedly mounted on the base and a second slider slidably sleeved on the guide rail. A knurled bolt, which abuts against the guide rail, is threaded into the top of the second slider. The limit switch is fixedly mounted on the bottom of the second slider. This adjusting mechanism allows for flexible adjustment of the limit switch position. Through the sliding engagement between the guide rail and the second slider, the distance between the limit switch and the base can be easily changed, meeting the personalized requirements for hydraulic cylinder stroke limitation during the testing of connectors of different sizes, thus improving the versatility and adaptability of the testing device. The knurled bolt securely fixes the second slider to the guide rail after the position is adjusted, ensuring the stability of the limit switch position during testing and guaranteeing the accuracy and reliability of the limit function.

[0008] Preferably, to facilitate fine-tuning of the hydraulic cylinder's lateral position: a first slider is fixedly connected to the bottom of the hydraulic cylinder; the output end of the hydraulic cylinder passes through the first slider and is fixedly connected to the movable clamp; a one-way lead screw, rotatably connected to the bracket, is threaded into one side of the first slider via a threaded hole; one end of the one-way lead screw passes through the bracket; a first motor, electrically connected to the controller, is fixedly mounted on the outside of the bracket; the output end of the first motor is fixedly connected to the end of the one-way lead screw; and a guide rod, fixedly connected to the bracket, is slidably inserted into the other side of the first slider via a round hole. This structure allows for convenient fine-tuning of the hydraulic cylinder's lateral position. By driving the one-way lead screw to rotate via the first motor, the first slider fixed to the bottom of the hydraulic cylinder can be moved laterally along the bracket under the guidance of the guide rod, achieving precise adjustment of the hydraulic cylinder's position. This function helps to accurately align the movable clamp with connectors at different positions during the testing process, improving the accuracy and efficiency of testing, reducing testing errors and operational inconveniences caused by positional deviations, and enhancing the practicality of the testing device.

[0009] Preferably, to clamp connectors of different sizes: both the fixed clamp and the movable clamp include a fixed base and clamping plates symmetrically slidably sleeved on the fixed base. The fixed base has a guide groove, and a bidirectional lead screw rotatably connected to the fixed base is disposed within the guide groove. Threaded sleeves symmetrically threaded onto the bidirectional lead screw are fixedly connected to the clamping plates. A second motor electrically connected to the controller is fixedly mounted at one end of the fixed base, and the output end of the second motor is fixedly connected to one end of the bidirectional lead screw. The fixed clamp and the movable clamp can stably clamp connectors of different sizes. By driving the bidirectional lead screw to rotate via the second motor, the threaded sleeves symmetrically mounted on the bidirectional lead screw can cause the clamping plates to slide towards or away from each other within the guide groove of the fixed base, thereby flexibly adjusting the distance between the clamping plates to adapt to the clamping requirements of connectors of different sizes.

[0010] Preferably, to reduce scratches on the connector surface caused by the clamping plate: an anti-slip pad is fixedly connected to the inner side of the clamping plate, and the outer surface of the anti-slip pad is provided with anti-slip texture. The anti-slip pad effectively reduces the risk of scratching the connector surface by the clamping plate. The anti-slip pad has a certain degree of softness, which allows it to fit tightly against the connector surface when clamping the connector, reducing hard contact; the anti-slip texture on its outer surface increases the friction with the connector surface, ensuring a firm clamping while avoiding scratches, wear, and other damage to the connector surface caused by excessive clamping force or surface friction, protecting the appearance and performance of the connector, improving the reliability of test results and the yield rate of the connector.

[0011] This application, through the cooperation of an indicator plate and a limit switch, can precisely limit the extension length of the hydraulic cylinder output end, effectively preventing collisions between the moving fixture and the fixed fixture, significantly improving safety during the testing process, preventing fixture damage and connector damage caused by collisions, reducing equipment maintenance costs and testing errors, and ensuring stable and reliable testing.

[0012] This application allows for easy adjustment of the distance between the limit switch and the base by sliding the guide rail and the second slider. This meets the personalized requirements for hydraulic cylinder stroke limitation when testing connectors of different sizes, improving the versatility and adaptability of the testing device. The knurled bolts can then firmly fix the second slider on the guide rail after the position is adjusted, ensuring the stability of the limit switch position during testing and guaranteeing the accuracy and reliability of the limit function.

[0013] This application utilizes a fixed clamp and a movable clamp to stably hold connectors of different sizes. A second motor drives a bidirectional lead screw to rotate, causing threaded sleeves symmetrically mounted on the lead screw to slide the clamping plates towards or away from each other within the guide groove of the fixed seat. This allows for flexible adjustment of the distance between the clamping plates, adapting to the clamping requirements of connectors of different sizes. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] This embodiment provides a testing device for computer connectors, such as... Figure 1-4 As shown, the testing device includes a base 1, a bracket 2 mounted on the base 1, a fixed clamp 3 mounted on the base 1, a movable clamp 4 mounted above the fixed clamp 3, and a hydraulic cylinder 5 mounted on the top of the bracket 2 for driving the movable clamp 4 to move closer to or away from the fixed clamp 3. A counter 6 is electrically connected to the hydraulic cylinder 5, and a controller 7 electrically connected to the hydraulic cylinder 5 and the counter 6 is mounted on the base 1. A limit switch 8 is mounted above the base 1 to limit the extension length of the output end of the hydraulic cylinder 5, and the installation height of the limit switch 8 is higher than the sum of the heights of the fixed clamp 3 and the movable clamp 4. An indicator plate 801 adapted to the limit switch 8 is fixedly connected to the output end of the hydraulic cylinder 5. Through the cooperation of the indicator plate 801 and the limit switch 8, the extension length of the output end of the hydraulic cylinder 5 can be precisely limited, effectively preventing the movable clamp 4 from colliding with the fixed clamp 3, significantly improving the safety during the testing process, preventing clamp damage and connector damage caused by collisions, reducing equipment maintenance costs and testing errors, and ensuring stable and reliable testing. When the output end of the hydraulic cylinder 5 moves the movable clamp 4 closer to the fixed clamp 3, it simultaneously moves the indicator plate 801 fixed to the output end downwards. When the indicator plate 801 moves to contact the limit switch 8, whose installation height is higher than the sum of the heights of the fixed clamp 3 and the movable clamp 4, the limit switch 8 triggers a signal. This signal is transmitted to the controller 7, which is electrically connected to the hydraulic cylinder 5. The controller 7 controls the hydraulic cylinder 5 to stop extending, thereby limiting the extension length of the output end of the hydraulic cylinder 5.

[0022] The base 1 is equipped with an adjustment mechanism 9 for driving the limit switch 8 to move closer to or further away from the base 1. The adjustment mechanism 9 includes a guide rail 901 fixedly mounted on the base 1 and a second slider 902 slidably sleeved on the guide rail 901. A knurled bolt 903, which abuts against the guide rail 901, is threaded into the top of the second slider 902. The limit switch 8 is fixedly mounted on the bottom of the second slider 902. The adjustment mechanism 9 allows for flexible adjustment of the position of the limit switch 8. Through the sliding engagement of the guide rail 901 and the second slider 902, the distance of the limit switch 8 closer to or further away from the base 1 can be easily changed, meeting the personalized requirements for limiting the stroke of the hydraulic cylinder 5 during the testing of connectors of different sizes, thus improving the versatility and adaptability of the testing device. The knurled bolt 903 securely fixes the second slider 902 to the guide rail 901 after the position is adjusted, ensuring the stability of the limit switch 8 during testing and guaranteeing the accuracy and reliability of the limit function. When the position of the limit switch 8 needs to be adjusted, loosen the knurled bolt 903 so that it no longer abuts against the guide rail 901. At this time, the second slider 902 can slide freely on the guide rail 901. According to the testing requirements, after sliding the second slider 902 to the appropriate position, tighten the knurled bolt 903 so that it is in close contact with the guide rail 901, thereby fixing the second slider 902 and thus fixing the position of the limit switch 8, realizing the adjustment of the stroke limit position of the hydraulic cylinder 5.

[0023] To facilitate fine-tuning of the lateral position of the hydraulic cylinder 5: a first slider 201 is fixedly connected to the bottom of the hydraulic cylinder 5. The output end of the hydraulic cylinder 5 passes through the first slider 201 and is fixedly connected to the movable clamp 4. A one-way screw 202, rotatably connected to the bracket 2, is threaded into one side of the first slider 201 via a threaded hole. One end of the one-way screw 202 passes through the bracket 2. A first motor 203, electrically connected to the controller 7, is fixedly installed on the outside of the bracket 2. The output end of the first motor 203 is fixedly connected to the end of the one-way screw 202. A guide rod 204, fixedly connected to the bracket 2, is slidably inserted into the other side of the first slider 201 via a round hole. This structure allows for convenient fine-tuning of the lateral position of the hydraulic cylinder 5. By driving the one-way screw 202 to rotate through the first motor 203, the first slider 201, fixed to the bottom of the hydraulic cylinder 5, can move laterally along the bracket 2 under the guidance of the guide rod 204, thus achieving precise adjustment of the position of the hydraulic cylinder 5. This function helps to precisely align the movable fixture 4 with connectors at different positions during the inspection process, improving the accuracy and efficiency of the inspection, reducing inspection errors and operational inconvenience caused by positional deviations, and enhancing the practicality of the inspection device. When it is necessary to make a fine adjustment to the lateral position of the hydraulic cylinder 5, the controller 7 sends a command to the first motor 203, which starts and drives the one-way lead screw 202 to rotate. Since one side of the first slider 201 is threaded into the one-way lead screw 202 through a threaded hole, and the other side is slidably sleeved on the guide rod 204 through a round hole, when the one-way lead screw 202 rotates, the first slider 201 will move laterally along the axial direction of the lead screw under the restriction of the guide rod 204, thereby driving the hydraulic cylinder 5 to move synchronously and completing the fine adjustment of the position.

[0024] To clamp connectors of different sizes, both the fixed clamp 3 and the movable clamp 4 include a fixed base 301 and clamping plates 302 symmetrically slidably sleeved on the fixed base 301. The fixed base 301 has a guide groove 303, within which a bidirectional lead screw 304 rotatably connects to the fixed base 301. Threaded sleeves 305, fixedly connected to the clamping plates 302, are symmetrically threaded onto the bidirectional lead screw 304. A second motor 306, electrically connected to the controller 7, is fixedly mounted at one end of the fixed base 301, and the output end of the second motor 306 is fixedly connected to one end of the bidirectional lead screw 304. The fixed clamp 3 and the movable clamp 4 can stably clamp connectors of different sizes. The second motor 306 drives the bidirectional lead screw 304 to rotate, causing the threaded sleeves 305 symmetrically mounted on the bidirectional lead screw 304 to slide the clamping plates 302 in opposite directions within the guide groove 303 of the fixed base 301. This allows for flexible adjustment of the distance between the clamping plates 302 to accommodate connectors of different sizes. When different sizes of connectors need to be clamped, the controller 7 starts the second motor 306, which drives the bidirectional lead screw 304 to rotate. Since the threads at both ends of the bidirectional lead screw 304 rotate in opposite directions, the threaded sleeves 305 symmetrically mounted on it move in opposite directions along the guide groove 303 as the lead screw rotates. The threaded sleeves 305 drive the clamping plates 302 fixedly connected to them to move synchronously, thereby adjusting the distance between the clamping plates 302 until the connector is stably clamped in the appropriate position.

[0025] To reduce scratches on the connector surface caused by the clamping plate 302, an anti-slip pad 307 is fixedly connected to the inner side of the clamping plate 302, and the outer surface of the anti-slip pad 307 is provided with anti-slip texture. The anti-slip pad 307 effectively reduces the risk of scratching the connector surface caused by the clamping plate 302. The anti-slip pad 307 has a certain degree of flexibility, which allows it to fit tightly against the connector surface when clamping the connector, reducing hard contact; the anti-slip texture on its outer surface increases the friction with the connector surface, ensuring a firm clamping while avoiding scratches, wear, and other damage to the connector surface caused by excessive clamping force or surface friction, protecting the appearance and performance of the connector, improving the reliability of test results and the yield rate of the connector. When the clamping plate 302 clamps the connector under the drive of the bidirectional lead screw 304, the anti-slip pad 307 on the inner side of the clamping plate 302 first contacts the connector surface. The soft material of the anti-slip pad 307 will deform slightly under pressure, tightly wrapping the connector surface; at the same time, the anti-slip texture creates multi-point friction with the connector surface, dispersing contact pressure while providing sufficient clamping force, preventing the clamping plate 302 from directly scratching the connector surface, thus protecting the connector. The anti-slip pad 307 is made of rubber or silicone.

[0026] The wiring diagrams of the first motor 203 and the second motor 306 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring arrangement of the first motor 203 and the second motor 306 will not be explained in detail.

[0027] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0028] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0029] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
