Description

Technical Field

[0001] This invention belongs to the field of connector testing technology, specifically relating to a positioning mechanism for a crystal head female connector used in connector production testing, and a testing device including the positioning mechanism. Background Technology

[0002] In fields such as network communication, industrial control, and consumer electronics, crystal heads (RJ45 connectors) and their corresponding female sockets (also known as network ports or information sockets) are widely used electrical connection devices. To ensure that the electrical and mechanical mating performance of these connectors meets standards, rigorous electrical performance tests, such as continuity tests, withstand voltage tests, and insulation resistance tests, must be conducted on the finished or semi-finished products during the manufacturing process.

[0003] In existing testing processes, manual or semi-automated testing fixtures are typically used. Operators need to place the female connectors to be tested one by one into the positioning slots of the fixture, then manually operate the clamping mechanism, insert the RJ45 test head and probe module, and finally start the electrical testing machine to read the data. This traditional method has the following significant drawbacks and shortcomings: 1. Unstable positioning effect: Existing fixtures have simple positioning structures, usually relying solely on the contour of the positioning groove for limiting, lacking a multi-directional, adjustable active clamping mechanism. During the insertion and removal of the test head, the female socket is prone to slight displacement, leading to poor probe contact or distortion of insertion and removal force test data, affecting the accuracy and consistency of test results.

[0004] 2. Low efficiency and high cost of manual operation: Multiple steps such as feeding, clamping, and splicing rely on manual labor to complete one by one, which is cumbersome and makes it difficult to achieve rapid turnover. When large-scale testing is required, a large amount of manpower is needed, and human fatigue can easily lead to errors, resulting in low overall testing efficiency and high labor costs.

[0005] 3. Lack of modularity and standardization in fixtures: Existing fixtures are mostly integrated designs for a single product model. When the specifications of the female connector product change slightly (such as different dimensions or pin positions), it is often necessary to redesign and manufacture the entire fixture, resulting in long adjustment cycles, high modification costs, and an inability to quickly respond to changing production needs.

[0006] 4. High barriers to entry for fully automated solutions: Although some fully automated testing equipment exists on the market, it typically integrates high-precision servo drives, vision positioning systems, and complex robotic arms, resulting in high equipment costs, high energy consumption, and complex maintenance. For many small and medium-sized manufacturing enterprises, this type of "large and comprehensive" solution is not advantageous in terms of economy and flexibility, and has a long development and debugging cycle.

[0007] Therefore, how to design a mother seat positioning mechanism and testing device that is simple and reliable in structure, accurate in positioning, supports rapid model changeover, has controllable cost, and can significantly improve testing efficiency is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] The present invention aims to solve one or more of the above-mentioned problems in the prior art and to provide a novel crystal head female positioning mechanism and testing device.

[0009] To achieve the above objectives, in one aspect, the present invention provides a crystal head female positioning mechanism, which includes: Machine tool; The first pressing assembly, fixedly installed on the machine base, includes a carrier plate, a first driver, a first pressure rod, a first pressure block, an end plate, and a side panel. The first driver is fixedly installed at one end of the carrier plate and drives the first pressure rod. The first pressure block has an L-shaped structure, and multiple first pressure blocks are evenly arranged along the length direction of the first pressure rod. Two end plates are respectively arranged at both ends of the carrier plate and are passed through by the first pressure rod. Multiple side panels are symmetrically arranged on both sides of the carrier plate, and the end plates and the side panels together form a carrier receiving cavity. A female carrier is detachably installed in the carrier receiving cavity. The female carrier has a plurality of positioning grooves, each positioning groove being used to receive and position a female carrier to be tested. Each positioning groove has a through clearance groove on its side, through which the first pressure block passes. The first driver drives the first pressure rod to perform linear reciprocating motion, and the first pressure rod drives the first pressure block to press the female seat to be tested into the positioning groove in the first direction. The positioning groove is adapted to the first pressure block to press and position the female seat to be tested. The second pressing assembly is fixedly installed on the machine base and includes a support, a second driver, a rocker arm, a second pressure rod, and a second pressure block. Two supports are symmetrically fixedly installed on the machine base. The rocker arm has a V-shaped structure and is rotatably mounted on the support. The second driver is fixedly installed on the machine base and drives one end of the rocker arm. The other end of the rocker arm is fixedly installed with the second pressure rod. A plurality of second pressure blocks are evenly arranged along the length direction of the second pressure rod. The second driver drives the rocker arm to swing, the rocker arm rotates around its rotation center and drives the second pressure rod to move in an arc. The second pressure rod drives the second pressure block to press the female seat to be tested into the positioning groove in the second direction. The positioning groove is adapted to the second pressure block to press and position the female seat to be tested.

[0010] Preferably, the first pressure rod is connected to a stabilizing seat at both ends, and the stabilizing seat is slidably mounted on the carrier plate.

[0011] Preferably, the bottom of the stabilizer is provided with a first slider, and the carrier plate is provided with a first slide rail, wherein the first slider is slidably mounted to fit the first slide rail.

[0012] Preferably, the carrier plate is provided with a plurality of positioning posts on its upper surface, the positioning posts being located within the receiving cavity, and the bottom surface of the female carrier is provided with a limiting groove corresponding to the positioning posts, the female carrier being positioned and installed by adapting to the positioning posts through the limiting groove.

[0013] Preferably, the rocker arm is rotatably connected to the support via a pin.

[0014] Preferably, the female carrier includes a base, a first template and a second template. The base is symmetrically provided with mounting grooves. The first template and the second template are respectively fixedly installed in the mounting grooves. Replacing different first templates and second templates can change the specifications of the positioning grooves to adapt to different female carrier positioning.

[0015] Preferably, the bottom of the substrate is provided with a through groove along its length, and the through groove is adapted to be installed relatively movable to the first pressure rod.

[0016] Preferably, the machine base also integrates a control module and a control switch. The control module is electrically connected to the first driver and the second driver, and the control module controls the first driver and the second driver to work in an orderly manner according to a preset program through the control switch.

[0017] On the other hand, the present invention also provides a testing device, including the crystal head female positioning mechanism described above, and further including: The first test module is slidably mounted on the machine base and includes a third driver and multiple crystal head modules. The third driver drives and connects the crystal head modules. The first test module is located on one side of the first clamping assembly. The third driver can drive the crystal head modules to electrically connect to the female connector under test located on the positioning slot. The second test module is slidably mounted on the machine base and includes a fourth driver and multiple probe modules. The fourth driver drives the probe modules. The second test module is located on the other side of the first clamping assembly. The fourth driver can drive the probe modules to electrically connect to the test socket located on the positioning groove.

[0018] Preferably, the machine base is provided with a second slide rail and a third slide rail, the bottom of the crystal head module is equipped with a second slider, the bottom of the probe module is equipped with a third slider, the second slider is slidably mounted to the second slide rail, and the third slider is slidably mounted to the third slide rail.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. High positioning accuracy and good stability: This invention abandons the passive method of traditional fixtures that rely solely on the contour limitation of the positioning groove, and innovatively adopts an active bidirectional clamping mechanism combining a first clamping component (horizontal direction) and a second clamping component (vertical or lateral direction). The first clamping component achieves synchronous horizontal clamping at multiple stations through a linearly driven L-shaped clamping block, while the second clamping component utilizes the force amplification and self-locking characteristics of a V-shaped rocker arm to achieve reliable clamping in the vertical direction. The clamping actions in the two directions are independent and sequentially controllable, which can firmly fix the female connector under test on the reference surface of the positioning groove, effectively avoiding female connector displacement caused by the insertion and extraction force of the crystal head or probe, and significantly improving the repeatability and consistency of test results.

[0020] 2. High testing efficiency and support for rapid product changeover: This invention features a modular female carrier that can be quickly disassembled as a whole. The carrier achieves precise pin-type positioning through a limiting groove at the bottom and positioning posts on the carrier plate, allowing operators to complete the loading and unloading of an entire batch of products within seconds. Simultaneously, the carrier itself adopts a combined structure of a base and replaceable templates (first template, second template). When product specifications change, only the low-cost templates need to be replaced for adaptation, without the need to replace the entire carrier or adjust the entire clamping system. This design reduces product changeover time from several hours to just a few minutes, significantly improving the flexibility and responsiveness of the production line.

[0021] 3. Simple and reliable structure with significant cost advantages: Compared to fully automated high-end equipment that relies on servo motors, precision guide rails, and vision systems, this invention extensively uses mature and low-cost mechanical transmission components such as standard cylinders, linear guide rails, and pin-shaft rocker arms. The entire mechanism is ingeniously designed and logically clear, requiring no complex programming or debugging. While achieving semi-automatic / fully automatic testing processes, it significantly reduces the manufacturing cost, maintenance cost, and energy consumption of the equipment, making it particularly suitable for large-scale application by cost-sensitive small and medium-sized manufacturing enterprises.

[0022] 4. Automated Testing Process, Reduced Reliance on Manual Labor: The integrated testing device of this invention, through unified scheduling by control modules such as PLC, achieves full automation of the entire process from "product clamping → test module docking → electrical performance testing → automatic reset". Operators only need to perform two simple actions: placing the device in the carrier and pressing the start button; all other insertion / removal and testing steps are completed automatically by the equipment. This not only significantly reduces the skill requirements for operators and alleviates labor intensity, but also avoids the risk of testing errors or product damage caused by inconsistencies in manual operation.

[0023] In summary, this invention achieves an excellent balance between positioning accuracy, changeover efficiency, manufacturing cost, and automation through its ingenious mechanical structure design, providing a highly practical technical solution for batch electrical performance testing of connector products such as crystal head sockets.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example like Figures 1-7 As shown, this embodiment provides a testing device for RJ45 female connectors. The testing device is equipped with a positioning mechanism for the RJ45 female connectors. Its core components include: a machine base 10 serving as an installation reference, and a first clamping component 20, a female connector carrier 30, and a second clamping component 40 fixedly mounted on the machine base 10. After the positioning mechanism clamps and positions the RJ45 female connector, performance testing can be performed.

[0031] Specifically, in this embodiment, please refer to the following: Figures 1-3 and Figure 6 The first clamping component 20 is the core module of this invention for achieving horizontal (first direction) clamping. It is fixedly mounted on a roughly rectangular flat plate 201. The plate 201 itself is securely connected to the table surface of the machine base 10 by bolts or other fasteners.

[0032] Among them, at one end of the carrier plate 201 (e.g. Figure 6 As shown on the left end, a first actuator 202 is horizontally mounted. In this embodiment, the first actuator 202 is preferably a double-acting, compound-actuated cylinder, because it has the advantages of fast response speed, low cost, moderate output force, and easy control. Of course, in other modified embodiments, the first actuator 202 can also be an electric actuator or a hydraulic cylinder.

[0033] In this design, the piston rod (i.e., the power output end) of the first actuator 202 is connected to the end of a long, narrow first pressure rod 203 via a floating joint. The first actuator 202 can drive the first pressure rod 203 to perform linear reciprocating motion. The floating joint can compensate for minor coaxiality errors between the piston rod and the first pressure rod 203, preventing jamming. The main body of the first pressure rod 203 is a long rod with a rectangular cross-section to ensure sufficient bending stiffness.

[0034] Multiple first pressure blocks 204 are fixedly arranged at equal intervals along the length of the first pressure rod 203. The shape of the first pressure block 204 is designed as L-shaped, with one arm fixedly connected to the first pressure rod 203 (e.g., by screws or welding), and the other arm extending in the forward direction of the first pressure rod 203 for direct contact and pressing against the female seat 50 to be tested.

[0035] To ensure the stability and straightness of the first pressure rod 203 during long-distance reciprocating motion, a stabilizing seat 208 is provided at each of its two ends. A first slider 209 is fixedly mounted on the bottom of the stabilizing seat 208, while two parallel first slide rails 210 are correspondingly mounted on the carrier plate 201. The first slider 209 and the first slide rails 210 are precisely fitted together to form a linear guide pair. This design allows the entire first pressure rod 203, along with the first pressure block 204 on it, to move smoothly like a slide table on a precision machine tool, greatly improving the repeatability accuracy of the pressing position.

[0036] At both ends of the carrier plate 201, two end plates 205 are fixed vertically upwards. These two end plates 205 have guide holes that match the cross-sectional shape of the first pressure rod 203. The first pressure rod 203 passes through these guide holes, providing further support and guidance. On both sides of the carrier plate 201, multiple side panels 206 are symmetrically fixed. These end plates 205 and side panels 206 together form a rectangular space with an open top, namely the carrier receiving cavity 207. The size of this receiving cavity forms a clearance fit with the outer contour dimensions of the female carrier 30, ensuring that the female carrier 30 can be easily inserted without significant shaking.

[0037] Furthermore, in this embodiment, please refer to the following key points. Figures 1-5 The mother carrier 30 adopts a modular design. It is a detachable, independent component, with its main body being a base 301. The base 301 is typically made of wear-resistant and dimensionally stable engineering plastics (such as bakelite or glass fiber reinforced plastics) or aluminum alloys (such as A6061).

[0038] In this embodiment, multiple parallel positioning grooves 304 are formed on the base 301 along its length. To test six products simultaneously, six positioning grooves 304 are provided. The shape of each positioning groove 304 conforms to the outer contour of the female connector 50 under test, but is not a perfect fit; a small adjustment gap is reserved.

[0039] Each positioning slot 304 has a through-hole 305 on its side (the side closest to the first driver 202). When the female carrier 30 is correctly placed into the carrier receiving cavity 207, each first pressing block 204 on the first pressing assembly 20 will pass exactly through a corresponding through-hole 305, with the front end of the first pressing block 204 facing the side of the female carrier 50 to be tested on the positioning slot 304. In this way, the first pressing block 204 can directly contact the side of the female carrier 50 to be tested located in the positioning slot 304 during movement, pressing it against the opposite side.

[0040] The mother carrier 30 of this invention has a modular interchangeable structure. Specifically, from Figure 5 The exploded view clearly shows that symmetrical mounting slots 307 are formed on both sides of the base 301. The first template 302 and the second template 303 are fixed in these two mounting slots 307 by screws. The complete shape of the positioning slot 304 is actually formed by the bottom surface of the base 301, the inner side surface of the first template 302, and the inner side surface of the second template 303. Therefore, when it is necessary to test the female base with different widths or different shape features, it is only necessary to replace the first template 302 and the second template 303 with the corresponding inner contours, while the main structures such as the base 301 and the spacing of the positioning slots 304 remain unchanged. This greatly reduces the cost and time of model changeover.

[0041] The base 301 has a through groove 308 extending along its length at its bottom. The position of the through groove 308 corresponds to the first pressure rod 203. When the female carrier 30 is installed in the carrier receiving cavity 207, the first pressure rod 203 is accommodated in the through groove 308 and can move freely back and forth. This "embedded" design makes the overall structure more compact.

[0042] Furthermore, to achieve rapid and precise positioning of the female carrier 30 on the carrier plate 201, multiple vertical positioning posts 211 are provided on the upper surface of the carrier plate 201, in the area located within the carrier receiving cavity 207. Correspondingly, limiting grooves 306 (usually blind holes or through holes) corresponding to the positioning posts 211 are formed on the bottom surface of the base 301 of the female carrier 30. During installation, simply place the female carrier 30 into the carrier receiving cavity 207, align the limiting grooves 306 at its bottom, and fit them onto the positioning posts 211 to complete precise positioning in the X and Y directions. This pin positioning method is simple and reliable, and is key to achieving the "quick release" function.

[0043] Furthermore, in this embodiment, please refer to the following key points. Figures 1-3 and Figure 7 The second clamping assembly 40 is responsible for clamping the female seat 50 to be tested in the vertical direction (second direction). It mainly includes a support 401, a second driver 402, a rocker arm 403, a second pressure rod 404, and a second pressure block 405.

[0044] Two identical supports 401 are symmetrically fixedly mounted on the machine base 10 and arranged on one side of the first clamping assembly 20. Each support 401 is rotatably connected to a rocker arm 403 via a high-strength pin 406. The rocker arm 403 has a V-shaped structure, with its corners connected to the pin 406 via bearings to reduce rotational friction. Preferably, the included angle of the V-shape is 120-150 degrees.

[0045] The second actuator 402 is preferably a cylinder, the cylinder body of which is mounted on the machine base 10 via a hinged seat, allowing it to swing within a small range to adapt to the arc motion trajectory of the end of the rocker arm 403. The piston rod of the second actuator 402 is connected to one end (active arm) of the rocker arm 403 via a pin or a joint bearing, and the second actuator 402 drives the rocker arm 403 to perform a swing arm movement.

[0046] The other end of the rocker arm 403 (driven arm) is fixedly connected to the second pressure rod 404. The second pressure rod 404 is a long rod that spans the entire length of the female carrier 30. On the second pressure rod 404, corresponding to the position of each positioning slot 304 on the female carrier 30, a second pressure block 405 is fixedly installed. The shape of the second pressure block 405 is designed according to the pressing direction. In this embodiment, pressing is required from top to bottom, so the second pressure block 405 can be designed with a downward protruding pressure head.

[0047] When the piston rod of the second actuator 402 extends, it pushes the active arm of the rocker arm 403 forward. The rocker arm 403 rotates counterclockwise around the pivot 406 (rotation center), and its driven arm drives the second pressure rod 404 and the second pressure block 405 to move downward in an arc, thereby pressing the female seat 50 under test against the bottom surface of the positioning groove 304. Due to the force-multiplying effect of the rocker arm mechanism, the second actuator 402 can generate a large end-pressing force with a relatively small force, and can achieve self-locking at the end of the stroke (when the active arm of the V-shaped rocker arm is close to a straight line with the piston rod), ensuring a stable and reliable pressing state.

[0048] Furthermore, the working process of this positioning mechanism is as follows: In the initial state, both the first driver 202 and the second driver 402 are in a retracted state, and the first pressure block 204 and the second pressure block 405 are away from the positioning groove 304 of the mother carrier 30.

[0049] The operator places the female connectors 50 to be tested one by one into the respective positioning slots 304 of the female connector carrier 30. At this time, the female connectors 50 to be tested are only roughly located in the slots and are not compacted.

[0050] The operator places the entire female carrier 30 filled with products into the carrier receiving cavity 207 of the first pressing assembly 20, and achieves precise alignment through the positioning post 211 and the limiting groove 306. The first pressing block 204 passes through the clearance groove 305 and its forward end faces the female carrier 50 to be tested in the positioning groove 304.

[0051] The operator presses control switch 80. The control module (not shown) first sends a signal to the solenoid valve of the first driver 202, driving its piston rod to extend. The control module is preferably a PLC control module. The piston rod pushes the first pressure rod 203, which moves forward smoothly under the guidance of the stabilizer 208, the first slide rail 210, and the end plate 205. The first pressure rod 203 drives all the first pressure blocks 204 to move synchronously. The advancing end of the first pressure block 204 pushes each female seat 50 to be tested from the side (first direction) towards the other side wall of the positioning groove 304 until they are completely fitted. The first pressing action is completed.

[0052] Subsequently, the control module sends a signal to the solenoid valve of the second actuator 402, driving its piston rod to extend. The piston rod pushes the rocker arm 403 to rotate, and the rocker arm 403 drives the second pressure rod 404 and the second pressure block 405 to move, pressing the female seat 50 under test from the vertical direction (second direction). At this time, the female seat 50 under test is completely fixed in the positioning groove 304 by forces in two directions, achieving high-precision and stable positioning.

[0053] After the test is completed, the control module releases the clamping force in the reverse order (first the second drive 402 retracts, then the first drive 202 retracts), and the operator can then remove the female carrier 30 and replace it with the next batch of products.

[0054] Furthermore, such as Figures 1-3 As shown, this embodiment provides a testing device that integrates the above-mentioned positioning mechanism, and also includes a first testing module 60 and a second testing module 70, for testing the crystal head female connector.

[0055] Specifically, the first test module 60 is located on the rear side of the positioning mechanism (within the rear side of the positioning mechanism). Figure 3(For reference only). It includes a third driver 601 and a crystal head module 602 connected to the third driver 601, wherein the third driver 601 is preferably a cylinder. The crystal head module 602 may integrate a standard crystal head plug, circuit board, and signal lines, etc. The third driver 601 is fixed on the machine base 10, and its piston rod is connected to the crystal head module 602. A second slider 604 is installed at the bottom of the crystal head module 602, and a second slide rail 603 that mates with it is installed on the machine base 10. When the third driver 601 is activated, the crystal head module 602 moves precisely back and forth along the second slide rail 603 to achieve insertion or disconnection with the female connector 50 under test.

[0056] Furthermore, the second test module 70 is positioned at the front of the positioning mechanism. It includes a fourth actuator 701 and a probe module 702 connected to the fourth actuator 701, wherein the fourth actuator 701 is preferably a cylinder. The probe module 702 can integrate multiple high-precision spring probes (pogo pins) for making electrical contact with the pins or solder joints of the female connector 50 under test. A third slider 704 is mounted on the bottom of the probe module 702, and a cooperating third slide rail 703 is mounted on the machine base 10. When the fourth actuator 701 is activated, the probe module 702 moves precisely back and forth along the third slide rail 703, causing the probes to contact or disengage from the female connector pins.

[0057] Furthermore, to improve testing efficiency, the entire testing device can operate automatically in the following sequence under the unified scheduling of the control module: Material loading and positioning stage: The operator puts the 6 test female seats 50 into the female seat carrier 30, then puts the carrier into the carrier receiving cavity 207 and presses the start button.

[0058] Product clamping stage: As mentioned above, the first clamping component 20 and the second clamping component 40 operate in sequence to accurately and firmly position the six products in their respective positioning slots 304 from two different directions.

[0059] During the testing and docking phase: The control module first controls the third driver 601 to move the crystal head module 602 forward, inserting the crystal head connector into the RJ45 interface of the female connector under test 50. Subsequently, the control module controls the fourth driver 701 to move the probe module 702 backward, ensuring reliable contact between the probe and the pins of the female connector under test 50. It should be noted that when setting the test program, the fourth driver 701 can also activate first, followed by the third driver 601.

[0060] Electrical performance testing phase: Both the RJ45 connector module 602 and the probe module 702 are connected to an external electrical performance tester (such as a network analyzer, withstand voltage tester, etc.) via cables to begin power-on testing. After the control module provides a trigger signal, the tester begins to execute preset test items, such as: continuity resistance, insulation resistance, dielectric strength, near-end crosstalk, return loss, etc., and the test data is automatically recorded.

[0061] Reset and Unloading Stage: After the test is completed, the control module controls the third driver 601 and the fourth driver 701 to retract, causing the crystal head module 602 and the probe module 702 to detach from the product. Next, the second clamping assembly 40 and the first clamping assembly 20 retract sequentially, releasing the clamping force. The operator removes the female carrier 30 and sorts and places the products according to the test results (pass / fail indicator lights).

[0062] As can be seen from the above process, this testing device organically combines precise positioning with automated testing. Operators only need to perform simple loading and unloading actions, while all other pressing, insertion, testing, and resetting steps are completed automatically, greatly improving testing efficiency and consistency. Furthermore, due to the adoption of a modular positioning mechanism and a quick-change female carrier 30, the device can quickly adapt to different product models, exhibiting strong production flexibility.

[0063] Furthermore, in a preferred embodiment of the present invention, to ensure insulation performance during the testing process, the base 301 of the crystal head insertion module and the female carrier 30 is preferably made of bakelite (phenolic plastic) with excellent insulation properties; the probe insertion module, due to its requirement for higher dimensional stability and wear resistance, is preferably made of glass fiber reinforced plastic (FR4). The carrier plate 201, end plate 205, side plate 206, support 401, rocker arm 403, first pressure rod 203, second pressure rod 404, stabilizer 208, slider rail pair, etc., are preferably made of lightweight and high-strength aluminum alloy A6061 and undergo surface anodizing treatment to improve their corrosion resistance and surface hardness.

[0064] It should be noted that although this embodiment uses 6 workstations as an example, the principle and structure of the present invention can be expanded to 2, 4, 8 or more workstations according to actual production needs. Accordingly, the number of the first pressing block 204, the second pressing block 405, the positioning groove 304, the crystal head module 602, and the probe module 702 should also be adjusted accordingly.

[0065] In summary, the crystal head female connector positioning mechanism and testing device provided by the present invention, through the unique combination of the first clamping component, the second clamping component and the modular quick-release carrier, realizes a low-cost, high-efficiency, high-precision and easy-to-change female connector testing solution, which has extremely high industrial practical value and market promotion prospects.

[0066] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
