Abstract

This invention discloses a network module connection testing device, relating to the field of network connection testing technology. It includes a platform, a workstation track, a workpiece pushing system, a workpiece progressive conveying module, and a pressing system. The pressing system has a support and a clamping part at its end. The clamping part is slidably mounted on the support and equipped with a pushing part. A separable permanent magnet is located between the pushing part and the clamping part. The support has a counterweight. The workpiece is pushed and progressively conveyed to the testing station. After the clamping part clamps the wire, the pushing part applies a pulling force. The maximum attraction between the two permanent magnets is set as the sum of the preset pull-out force, the counterweight pulling force, and the frictional force. When the pulling force reaches the target, the permanent magnets separate, and the counterweight drives the clamping part to reset. The sensor detects the wire displacement to determine whether it is qualified or not. This invention eliminates the need to control the pull-out distance and can stably maintain the force after reaching the preset pulling force. It solves the problems of high cost, low efficiency, unstable load holding, and easy missed detection and non-compliance with standards in traditional equipment. It has a simple structure, stable testing, is suitable for batch testing on production lines, and meets the IDC terminal pull-out force standard requirements.

Description

Technical Field

[0001] This invention relates to the field of network connectivity detection technology, specifically to a network module connectivity detection device. Background Technology

[0002] In the field of network communication, RJ45 or similar network modules serve as the core connection components of integrated cabling systems. They have eight independent IDC (Insulation Displacement Connection) terminals on the back, arranged in two columns. The left column has terminals 1, 3, 5, and 7 in sequence, and the right column has terminals 2, 4, 6, and 8 in sequence. Each core of the 8-core network cable is inserted into an independent IDC terminal. The U-shaped tuning fork structure of the IDC terminal pierces the cable insulation layer and clamps the copper core, achieving mechanical fixation and electrical conduction.

[0003] According to international and domestic industry standards such as IEC 60352, UL 1863, and YD / T 926, pull-out force testing of network modules needs to be differentiated based on the scenario: For wall-mounted network modules used for external network connections, each core wire corresponds to an independent IDC terminal, and pull-out force testing must be performed on each wire individually to ensure reliable connection between the core wire and the terminal, guaranteeing network transmission stability. However, modules used internally for switching, not directly connected to the external network, and only responsible for internal signal transmission do not require pull-out force testing, as they do not require external pulling force and do not need to verify connection reliability through pull-out force testing. Therefore, pull-out force testing equipment has become an indispensable testing device in the production process of wall-mounted network modules, directly determining the product's qualification and safety in use.

[0004] Currently, the equipment used for testing the pull-out force of network module cables in the industry is mainly divided into two categories, but both have obvious technical defects and are difficult to meet the needs of efficient, accurate and standard-compliant batch testing.

[0005] The first type is direct force measurement testing equipment, which uses a structure where the tension sensor is arranged coaxially with the direction of the pull wire, and completes the test by acquiring dynamic force-displacement curves in real time. The core drawback of this type of equipment is that it requires strict control of the pull-out speed and pull-out distance during the test, and requires a precision servo displacement control system, resulting in a complex equipment structure and high manufacturing costs. At the same time, it is susceptible to the effects of inertia, vibration and sensor response lag during dynamic loading, resulting in large fluctuations in force value, making it difficult to achieve constant load after reaching the preset tension, and unable to truly simulate the "constant force continuous action" working condition required by the standard. In addition, the testing cycle of a single core wire is long and the detection efficiency is low, making it difficult to adapt to the batch one-by-one testing requirements of network module production lines, which restricts the improvement of production efficiency.

[0006] The second type is indirect detection testing equipment. This type of equipment does not directly measure the pull-out force on the core wire. Instead, it infers the reliability of the connection between the IDC terminal and the core wire by detecting indirect indicators such as whether the core wire displacement exceeds limits, whether the contact resistance changes abruptly, and whether the circuit is conductive. While this type of equipment is relatively simple in structure and low in cost, it suffers from serious reliability defects: Firstly, it lacks a real mechanical loading process, making it impossible to quantify the specific value of the pull-out force. The test results lack standard compliance and fail to meet the mandatory requirements of national and industry standards for quantitative verification of pull-out force. Secondly, it is prone to missed detections where "the displacement does not exceed limits but the core wire has loosened and the clamping has failed." Furthermore, the test results are greatly affected by factors such as cable deformation and fluctuations in contact status, resulting in poor repeatability and consistency. This makes it impossible to accurately reflect the actual clamping capacity of the IDC terminal, potentially leading to substandard products entering the market and creating hidden dangers for network transmission failures.

[0007] In summary, existing network module cable pull-out force testing equipment is either costly, inefficient, and has poor load-bearing capacity, or lacks sufficient testing accuracy, does not meet standards, and is prone to missed detections. None of these methods can effectively balance testing accuracy, standard compliance, and production efficiency. Therefore, developing a pull-out force testing device that can overcome these technical shortcomings, eliminates the need to control the pull-out distance, and stably maintains the applied force after reaching a predetermined pull-out force has become a pressing technical problem for those skilled in the art. To this end, we propose a connection testing device for network modules. Summary of the Invention

[0008] The purpose of this invention is to provide a network module connection detection device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a network module connection detection device, comprising a station track mounted on a platform, a workpiece pushing system on one side of the station track, a workpiece conveying module on the platform, several stations on the station track, and a mounting base on the platform corresponding to each station. A pressing system is mounted on the mounting base, a bracket is provided at the pressing end of the pressing system, and a clamping part for clamping wires is mounted on the bracket. The clamping part is slidably disposed on the bracket along the direction of the wire pull-out force, and a pushing part is provided on the bracket. Two [unclear] are provided between the working end of the pushing part and the clamping part. The two permanent magnets are relatively separable. The support is also equipped with a counterweight connected to the clamping part. The workpiece pushing system arranges the workpieces and sends individual workpieces into the workstation through the workpiece advancing and conveying module. The pressing system sends the clamping part into both sides of the wire and clamps the wire. Under the action of the pushing part, the wire is pulled to test the pull-out force. The maximum attraction between the two permanent magnets is the sum of the wire's preset pull-out force, the counterweight's pulling force, and the component's friction force. When the pushing part advances, when the pull-out force transmitted to the wire reaches the preset value, the two permanent magnets separate, and the counterweight resets the clamping part. The mounting base is also equipped with a sensor to detect the wire's displacement state.

[0010] Preferably, the propulsion unit includes a fixed plate installed at the end of the pressing system and synchronized with it. The fixed plate has a pressing plate that can be reset and slidably mounted along the normal direction of its lower end face. A bracket is fixedly mounted on the pressing plate. A base is slidably mounted at one end of the bracket. The bracket is mounted with a clamping part through the base. A sliding plate is slidably mounted in the middle of the pressing plate along the normal direction of its lower end face. A pull cable is connected to the sliding plate. A sleeve is slidably fitted between the two corresponding bases. Two permanent magnets are located in the sleeve. One permanent magnet is fixed to the base, and the other is connected to the sliding plate through the pull cable. A connecting rod is also provided on the pressing plate. When the fixed plate moves down, it abuts against the connecting rod, causing the sliding plate to move up and generate a pulling force.

[0011] Preferably, the clamping part includes two clamping arms, which are slidably and repositionably mounted on the base. A rotating arm is axially connected to the opposite sides of the two clamping arms. A protrusion and a matching groove are provided between the opposite sides of the rotating arm and the clamping arm. When the rotating arm is pressed down and rotated, the protrusion and groove push the clamping arms to move towards each other. A waist-shaped groove is provided in the middle of the rotating arm. A pressure rod is fixed to the lower end face of the fixed plate. When the rotating arm is not pressed down, the protrusion and groove are in a separated or engaged state. The end of the pressure rod is slidably connected to the waist-shaped groove of the rotating arm through the fixed shaft. A guide is also fixed under the lower pressure plate. The guide is used to limit the position of the base when the rotating arm rotates to prevent it from sliding.

[0012] Preferably, when the rotating arm is pressed down to a horizontal state, the straight section of the side wall where the waist-shaped groove contacts the fixed shaft on the pressure rod tilts downward from the shaft connection end of the rotating arm to the other end, and the moving distance of the base driven by the contact rod is greater than the moving distance of the base pushed by the rotating arm when it rotates.

[0013] Preferably, both the sleeve and the base are made of non-magnetic materials.

[0014] Preferably, the workstation track is equipped with two workstations, and the clamping parts on the different workstations are staggered and complementary.

[0015] Preferably, the clamping parts on the same workstation are spaced apart.

[0016] Preferably, the steel cables connected to the cable and the counterweight are both flexible traction components made of inelastic material.

[0017] Preferably, the end of the workstation track is provided with a sorting and collection area, which includes a sliding plate and a replacement mechanism. When the replacement mechanism is in the connected state, the workpiece is discharged from the sliding plate as a qualified workpiece, and when it is not in the replacement state, the workpiece falls into the unqualified product collection box.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a permanent magnet constant force loading mechanism, eliminating the need for precise control of pull-out distance and displacement, thus removing the need for a servo displacement control system and significantly reducing the complexity of the equipment structure and manufacturing costs. In this invention, the permanent magnet automatically separates when the tension reaches the preset value, and the force is maintained stably without overshoot or attenuation. It truly simulates the constant force load condition required by the standard, and the test results are more in line with actual use scenarios. This invention uses a mechanical structure to achieve quantitative output and load holding of tensile force, which is not affected by inertia, vibration and electrical response lag, and has strong test repeatability and consistency, avoiding missed judgments and misjudgments; This invention enables rapid testing of each core wire, with a short testing cycle per workstation, adapting to the batch testing needs of network module production lines and significantly improving testing efficiency. This invention features a purely mechanical structure combined with sensor judgment, without complex electrical control and wiring, ensuring stable operation, easy maintenance, and compatibility with multiple network module detection specifications, making it highly versatile. The present invention enables automatic reset by separating the counterweight block with the permanent magnet, ensuring a continuous and smooth testing process. Combined with the end-of-line sorting and collection area, it can automatically sort qualified and unqualified products, reducing manual intervention. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1This invention provides a technical solution: a network module connection detection device, comprising a workpiece pushing system 3, a workstation track 2, a workpiece conveying module 4, and a sorting and collection area arranged sequentially from right to left on a platform 1. The workpiece pushing system 3 consists of a guide plate 301 and a pushing cylinder 302. The cross-section of the guide plate 301 conforms to the shape of the network module, and the upper part is open. One edge of the guide plate 301 is folded outward to facilitate the carrying of wires on the workpiece. A stop pin 303 is provided on the leftmost side of the guide plate 301. The stop pin 303 rotates forward under the push of the push cylinder 302. The network modules are arranged and conveyed on the guide plate 301. The push cylinder 302 moves in the front-back direction from the perspective shown in the figure. The front end of the push cylinder 302 is equipped with a single tool that is adapted to the network module. The single network module is sent to the end of the station track 2 through the tool. The workpiece advancing and conveying module 4 consists of a sliding platform 401 and a receiving tool 402. The number of receiving tools 402 corresponds to the station. The sliding platform 401 can slide in the front-back and left-right directions. In the first state, the rightmost receiving fixture 402 receives a workpiece. In this state, the receiving fixture 402 is connected to the guide plate 301, and the stop pin 303 blocks the wire. Then, it rotates to allow the wire to smoothly enter the receiving fixture 402 for easy transfer. Next, the sliding platform 401 moves to the left, moving the receiving fixture 402 with the workpiece to the next testing station. After testing, the sliding platform 401 moves forward, moving the receiving fixture 402 away from the testing station. After moving, the sliding platform 401 moves to the right and then backward, resetting the rightmost receiving fixture 402 to its original position. The next workpiece is pushed into the next receiving fixture and transferred to the next station. At the end of the station track 2 is the sorting and collection area, which mainly consists of a sliding plate 13 and a replacement mechanism 14. The end of the sliding plate 13 does not directly contact the station track 2, but is connected through the replacement mechanism 14. When connected, the workpiece discharged from the sliding plate 13 is a qualified workpiece. When the replacement mechanism 14 is not in the replacement state, the workpiece falls into the non-conforming product collection box 15 below and the test is completed. That is, the overall process is receiving → transfer → testing → sorting.

[0023] The workstation track 2 connects the guide plate 301 and the sliding plate 13, serving as a workpiece testing area. The workstation track 2 is installed on the platform 1. Figure 1 From this perspective, the workstation track 2 is located behind the sliding platform 401. The terminals on the network module are usually distributed in two rows, four in a single row, and two in a group, that is, divided into four groups in the longitudinal direction. The network module is relatively small, so multiple workstations are set up to test it sequentially, so as to avoid excessive integration leading to increased processing costs and higher precision required for use. Each group can be a single process, or two groups can be staggered, and they can also be horizontally staggered, that is, the terminals on the left and right sides of different groups can be tested simultaneously.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 7 A mounting base 5 is installed on platform 1, located behind the workstation track 2. A pressing system 6 is installed on the mounting base 5, positioned directly above the workstation. The pressing system 6 can move vertically. It is constructed using a combination of a slide rail 601 and a cylinder 602 or a telescopic motor. At the working end of the pressing system 6, a clamping part 8 corresponding to the wires on the network module terminals is installed via a bracket 7. The clamping part 8 is, for example, a controllable mechanical gripper with a control system. As the pressing system 6 moves, the clamping part 8 moves down to both sides of the wires and clamps them, achieving the purpose of clamping the wires. This clamping action is performed along the lateral direction of each set of terminals on the network module. Figure 1 The intermediate workstation track 2 has a pusher 9 mounted on the bracket 7 along its length. The pusher 9 is used to push the clamping part 8. After the clamping part 8 clamps the wire, it pushes and pulls to generate a pull-out test. Figure 7From the perspective shown, the left clamping part 8 moves to the right and pulls the wire under the action of the pushing part 9, while the right side moves in the opposite direction. Two permanent magnets 10 are provided between the pushing part 9 and the clamping part 8, and the permanent magnets 10 can move directionally along the direction of the pull-out force. A counterweight 11 is provided on the other side of the clamping part 8 opposite to the permanent magnets 10. The counterweight 11 is connected to the clamping part 8 by a steel cable 1101. After the clamping part 8 clamps the wire, the pushing part 9 generates a pulling force. The two permanent magnets 10 are initially in a state of contact and attraction. The pushing part 9 and the clamping part 8 move synchronously. When the wire is straightened, the pulling force on the wire increases, and the two permanent magnets 10... Two scenarios may occur: either the two permanent magnets 10 separate, or they remain in close contact and synchronized. The attraction between the two permanent magnets 10 is slightly greater than or equal to the sum of the pull-out force set for the network module wires and the pulling force generated by the counterweight 11. The existing pull-out force is generally ≥15N for a single wire, with commonly tested values ​​of 18N-20N. A predetermined value is selected based on the specific network module and terminals. The pull-out force is the maximum attraction between the two permanent magnets 10 (the maximum pulling force required to separate them) minus the pulling force of the counterweight 11. Therefore, the propulsion unit 9 does not need to control the thrust magnitude and can automatically detach or the wire detach from the terminal after reaching the predetermined value. The "slightly greater" mentioned above takes into account the sliding friction of each component, such as the friction of the clamping part 8 on the bracket 7. For example, if the friction is f, the pull-out force is set to F, the pull force of the counterweight 11 is A, and the maximum attraction of the two permanent magnets 10 is Y, the preferred state is Y > A + F and Y ≤ f + A + F. For specific parameter examples, if F = 18 N, A = 2 N, and f = 2 N, then Y takes the value of 21 N - 24 N. In this state, when the pull force of the pushing part 9 increases, it will first drive the wire and the counterweight 11 to move synchronously. When the pull force on the wire reaches the set pull-out force, the two permanent magnets 10 separate, and the clamping part 8 and the wire will be separated. The weight 11 resets the device. When the terminal is not securely clamped, the wire will be pulled out by the push part 9, and the two permanent magnets 10 will not separate. A sensor (not shown) is also provided on the mounting base 5. The sensor is used to detect the movement of the wire. Specifically, it can directly detect the movement distance of the permanent magnet 10 or the weight 11, or it can use a pressure sensor to monitor the change in gravity (or position change or tension change) of the weight 11. The two situations represent the product's qualification and non-qualification. That is, if the wire is securely connected to the terminal, the permanent magnet will separate first, and the wire pull-out force is qualified; if the connection is not secure, the wire will be pulled out, which is unqualified.

[0025] See Figure 3 , Figure 4 , Figure 5 and Figure 6The propulsion unit 9 includes a fixed plate 901 installed at the end of the pressing system 6. The fixed plate 901 moves synchronously with the pressing system 6. A pressing plate 902 is located directly below the fixed plate 901. The pressing plate 902 is slidably mounted on the fixed plate 901, and a spring or other reset component is provided between the two. Correspondingly, a limiting block 909 is provided on the mounting base 5 to limit the movement distance of the pressing plate 902. A bracket 7 is fixedly installed on the lower surface of the pressing plate 902, and the bracket 7 is hollow and L-shaped. A base 903 is slidably connected to the lower end of the bracket 7. The base 903 is used to install the clamping part 8. A through hole is opened in the middle area of ​​the pressing plate 902, and a sliding plate 904 is slidably connected to the side wall of the through hole in the vertical direction. The bottom of the sliding plate 904 is provided with There are several cables 905, each corresponding to the number of wires to be tested at a workstation. The other end of the cable 905 is used to connect to one of the permanent magnets 10 in the same group. The other permanent magnet 10 is fixed on the base 903. The two permanent magnets 10 are limited and oriented to slide by the sleeve 906. The two longitudinally corresponding (same group or staggered correspondence) use the same sleeve 906. A telescopic sleeve (not shown) is provided between the sleeve 906 and the slide plate 904. The telescopic sleeve limits the left and right movement of the sleeve 906. A connecting rod 907 is also provided on the lower pressure plate 902. The middle part of the connecting rod 907 is rotatably connected to the lower pressure plate 902 through a shaft. One end of the connecting rod 907 is opened with a long groove, which is slidably connected to the fixed shaft fixed on the slide plate 904 through the long groove.

[0026] When the pressing system 6 moves downward, it simultaneously drives the fixing plate 901 and the pressing plate 902 to move downward. This process sends the clamping end of the clamping part 8 to both sides of the wire. After reaching the position, the pressing plate 902 abuts against the limiting block 909, and the clamping part 8 clamps the wire. After clamping, the pressing system 6 continues to press down, and the fixing plate 901 abuts against one end of the connecting rod 907, causing the connecting rod 907 to pull the cable 905 to generate tension, thereby forming a pull-out force test.

[0027] See Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 The clamping part 8 consists of two clamping arms 801 slidably mounted on the base 903. A spring or other elastic reset element is provided between the two clamping arms 801. Figure 8From a certain perspective, the two clamping arms 801 slide along the longitudinal direction of the terminals. A guide post 810 is provided in the middle of the clamping arms 801 to restrict their movement. A rotating arm 802 is axially connected to the upper end of the clamping arms 801, with the other end of the rotating arm 802 being a free end. A waist-shaped groove 805 is formed at the free end or in the middle of the rotating arm 802. A pressure rod 806 is fixed to the lower surface of the fixing plate 901. The pressure rod 806 extends through a through hole in the lower pressure plate 902 to the waist-shaped groove 805 on the rotating arm 802 and is slidably connected to the waist-shaped groove 805 via a fixed shaft. A protrusion 803 or a groove 804 is provided on one side near the non-free end of the rotating arm 802. The corresponding clamping arm 801 has a groove 804 or a protrusion 803 on its side wall. By rotating the rotating arm 802, the protrusion 803 slides out of the groove 804, thereby pushing the two clamping arms 801 towards each other to produce a clamping action. When the rotating arm 802 is pushed by the pressure rod 806, a lateral force is generated, causing the base 903 to slide. Therefore, a guide 808 is also provided on the lower surface of the lower pressure plate 902. The guide 808 restricts the rotation of the rotating arm 802 so that it only rotates and does not move. That is, one side wall of the guide 808 is arc-shaped, and the axis of the arc-shaped surface coincides with the axis of rotation of the rotating arm 802. It is better when the restrictor 808 acts on the horizontal state of the rotating arm 802.

[0028] When the pressing system 6 moves downward, it simultaneously drives the fixed plate 901 and the pressing plate 902. When the lower ends of the two clamping arms 801 in the same group are located on both sides of the wire, the pressing plate 902 abuts against the limiting block 909. At the same time, the pressing rod 806 acts on the rotating arm 802, causing the protrusion 803 to gradually move out of the groove 804, so that the clamping arm 801 clamps. After clamping, when the rotating arm 802 rotates to a horizontal state, the fixed plate 901 contacts the connecting rod 907 and causes the cable 905 to pull the permanent cable. The magnet 10 generates a pull-out test. When the rotating arm 802 rotates to a horizontal state, the lateral force of the pressure rod 806 on the rotating arm 802 is minimal (theoretically zero). At this time, the interference factor of the pull-out force of the cable 905 is minimal. In order to achieve the optimal state, the lower straight section of the waist-shaped groove 805 on the rotating arm 802 is inclined, and it is inclined from the non-free end to the free end. This inclined setting allows the rotating arm 802 to move to the left with the base 903 when the rotating arm 802 is horizontal. Figure 10 (From a certain perspective), the pressure between the rotating arm 802 and the pressure rod 806 will decrease, thereby reducing the impact.

[0029] Furthermore, the two ends of the rotating shaft of the connecting rod 907 have a difference in force arm, and the downward movement of the fixed plate 901 causes the sliding movement to drive the rotating arm 802 to move to the left. Figure 10 The movement of the angle causes the pressure rod 806 to move downward, and at the same time, the waist-shaped groove 805 of the rotating arm 802 disengages from the fixed shaft on the pressure rod 806, thus completely eliminating the influence.

[0030] The integrated components enable pressing and clamping actions, making the overall mechanism more centralized and eliminating the need for excessive interference from external wires. Furthermore, the position of the wire to be tested can be adjusted by changing the position of the clamping arm 801 and the connecting cable 905 of the slide plate 904, resulting in high adaptability. In addition, the pure structure is more stable than electrical components.

[0031] All components around the permanent magnet 10 are made of non-magnetic materials to avoid interfering with the attraction between the permanent magnets 10. The cable 905 and the steel cable 1101 connected to the counterweight 11 are made of non-elastic materials to avoid affecting the test. They can automatically detach when the predetermined tension value is reached. The test generated by the scheme can also adapt to the tensile elasticity of the wire itself and the amount of free hanging movement (the amount of movement when pulled to the test horizontal state).

[0032] As one embodiment, a double station is set on the station track 2, and the clamping parts 8 on each station are staggered, that is, the terminals are evenly distributed. As a preferred option, two sets of terminals with a gap of one group are located in the same station. This arrangement can make the structures on the two sets of stations basically completely identical (because the distance between terminals 1 and 3 on the left column is the same as the distance between terminals 2 and 4), that is, the position distances relative to the mounting base 5 are different.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
