Abstract
Description
Technical Field
[0001] This application relates to the field of adapter board testing technology, specifically to an adapter board testing fixture. Background Technology
[0002] In the field of electronic equipment manufacturing and system integration, adapter boards are key components for realizing circuit connections, signal transmission, or interface conversion between different modules. Their electrical connection performance directly determines the stability and reliability of the entire electronic system. Whether in consumer electronics, industrial control equipment, or battery management systems (BMS) in the new energy field, adapter boards must ensure good conductivity between all pins and test points, without open circuits, short circuits, or poor contact. Otherwise, it will lead to system signal distortion, functional failure, or even equipment damage.
[0003] Currently, the testing of adapter board connection performance in the industry still largely relies on manual wiring: testers must hold wires or test probes and temporarily connect each test point on the adapter board to an external testing circuit one by one. They then use instruments such as multimeters and oscilloscopes to read the continuity status or signal parameters of each test point to ultimately determine whether the adapter board is qualified. However, this traditional testing method has the following significant technical problems:
[0004] ①Low testing efficiency: The number of test points on the adapter board is usually dozens or even hundreds. The manual connection and disconnection process is cumbersome and time-consuming. Especially in mass production scenarios, the testing time for a single adapter board can be as long as several minutes, which is difficult to meet the needs of efficient production and leads to limited production line capacity.
[0005] ② Poor test accuracy: Manual operation is easily affected by subjective factors, such as unstable contact pressure between the wire and the test point. If it is too loose, it will lead to poor contact; if it is too tight, it will damage the test point. If different test points are connected incorrectly, the wiring sequence will be confused. Instrument reading errors may also lead to misjudgment of test results, which will affect product quality control.
[0006] ③ High operational threshold and insufficient safety: Manual testing requires testers to be familiar with the circuit principle of the adapter board, the definition of test points and the operation of instruments, which requires high professional skills. At the same time, some adapter board tests need to be carried out in a powered state. When manually handling the wires, there is a risk of electric shock. In addition, metal wires and probes can easily scratch the circuits or components on the surface of the adapter board, causing secondary damage to the product.
[0007] Therefore, in response to the technical pain points of "low efficiency, poor accuracy, and complex operation" in existing adapter board testing methods, there is an urgent need in this field to develop an adapter board testing fixture that can achieve rapid connection of test points, intuitive judgment of results, and adaptability to batch testing, so as to solve the above technical problems and meet the needs of the electronic equipment manufacturing industry for efficient and accurate testing of adapter boards. Utility Model Content

[0015] Furthermore, the pressing mechanism also includes a fixed plate and a handle operating assembly that are detachably connected to the vertical support. One end of the handle operating assembly is fixedly connected to the fixed plate, and the other end is connected to the pressing plate.
[0016] Furthermore, the handle operation assembly includes a fixed frame, a handle rod, a central rod, and a hollow sleeve, with the central rod passing through the hollow sleeve and moving up and down along it.

The accompanying drawings, which constitute a part of this application, are used to provide a further understanding of this application. The illustrative embodiments and descriptions of this application are used to explain this utility model and do not constitute an improper limitation of the application.

[0034] It should be noted that, in this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "connection" can refer to a fixed connection, a detachable connection, or an integral part, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0036] Example 1
[0037] See Figure 1As shown, this embodiment provides a test fixture for an adapter board, including a fixture body 1. The fixture body 1 is the basic load-bearing and functional integration component of the test fixture, specifically composed of a horizontal base 2 and a vertical support 3. The horizontal base 2 is horizontally set to realize the positioning and installation of the adapter board and the integration of the test circuit. The vertical support 3 is vertically fixed to one side of the horizontal base 2 to support and install the pressing mechanism. Together, they form a stable "L"-shaped structure to ensure that the fixture does not shake during the test, providing a structural foundation for accurate testing.
[0038] Using the technical solution of this embodiment, the adapter plate testing fixture of this application implements the test process by installing and fixing the adapter plate in the limiting groove 20, and then operating the pressing mechanism to make the probe 421 of the pressing plate 42 quickly connect with the test point of the adapter plate. The result is visually detected by the indicator light 23, which has the beneficial effects of high testing efficiency and high accuracy.
[0039] Specifically, in this embodiment, the limiting groove 20 and the limiting post 21 of the horizontal base 2 are used to achieve precise positioning of the adapter plate and solve the problem of manual positioning deviation.
[0040] like Figure 1 As shown, the upper surface of the horizontal base 2 is provided with a limiting groove 20 that perfectly matches the shape and size of the adapter plate to be tested. The depth of the limiting groove 20 is slightly less than the thickness of the adapter plate, ensuring that the adapter plate can be limited by the groove wall after being placed in, avoiding horizontal displacement. At the same time, 2-6 limiting posts 21 are evenly arranged on the periphery of the limiting groove 20, and the periphery of the adapter plate to be tested is pre-set with limiting holes corresponding to the position and diameter of the limiting posts 21. When the adapter plate is placed in the limiting groove 20, the limiting posts 21 can be inserted into the limiting holes of the adapter plate, realizing the "unique position positioning" of the adapter plate in the limiting groove 20.
[0041] With the dual positioning structure of limiting groove and limiting post, the position of the adapter plate can be adjusted manually, ensuring that all test points of the adapter plate are precisely aligned with the probes of the subsequent pressure plate. This completely solves the problem of wiring misalignment caused by test point positioning deviation in traditional manual testing, providing a prerequisite for stable contact between the probe and the test point. At the same time, it simplifies the placement action of the operator, requiring only "place and lock" to complete the positioning, reducing the operation threshold.
[0042] Example 2
[0043] Based on Embodiment 1, this embodiment, as a preferred implementation, integrates a test circuit for detecting the connection performance of the adapter board inside the horizontal base 2. Figure 4As shown, the test circuit specifically includes a power supply module (such as a 12V DC power supply or a rechargeable lithium battery), several indicator lights 23 (such as LEDs, with colors selectable as red or green), and wires. During testing, simply turn on the power switch of the power supply module, and the connection performance of the adapter board can be directly judged by the on / off state of the indicator lights 23, thus solving the problem of "human reading error".
[0044] Specifically, the positive terminal of the power supply module is connected to the positive terminal of each indicator light 23 one by one through a wire, and the negative terminal of the indicator light 23 is connected to the probe 421 of the pressure plate one by one through a wire; the probe 421 and the test point of the adapter board are electrically connected through the pressing action of the pressing mechanism, thus forming a complete conductive loop of "power supply module → indicator light → probe → adapter board test point → adapter board internal circuit → power supply module negative terminal".
[0045] If all indicator lights 23 are lit, it means that the circuit between all test points on the adapter board is conducting normally and there is no open circuit or short circuit fault.
[0046] If one or more indicator lights 23 are not lit, it indicates that there is an open circuit in the circuit between the test points connected to the corresponding probe, such as a broken circuit or poor contact in the internal circuit of the adapter board. The faulty test point can be directly located by the "position of the indicator light that is not lit". For example, if the 3rd indicator light is not lit, it means that the 3rd group of test points on the corresponding adapter board is faulty.
[0047] This design eliminates the need for manual reading of instrument parameters, and the test results are intuitive and unambiguous, completely solving the problems of reading errors, omissions, and misrecordings in traditional manual testing. At the same time, it provides accurate fault location, facilitating rapid processing of subsequent maintenance procedures and further improving production efficiency.
[0048] Example 3
[0049] This embodiment, based on Embodiment 1 and Embodiment 2, is a preferred implementation method, such as... Figure 1 , Figure 2 As shown, a pressing mechanism is installed on the vertical support 3. This pressing mechanism enables rapid and stable contact between the probe and the test point, solving the problem of low efficiency in manual wiring. In this embodiment, the pressing mechanism is the core component for achieving rapid connection between the probe and the adapter board test point. Specifically, it includes a fixing plate 40, a handle operation assembly 41, and a pressing plate 42. The implementation methods and functions of each component are briefly described below:
[0050] In this embodiment, a fixed plate 40 is set to achieve a detachable connection between the pressing mechanism and the vertical support, thereby improving the compatibility of the tooling. The fixed plate 40 is detachably connected to the vertical support 3 by bolts. The fixed plate 40 or the vertical support 3 is provided with an elongated adjustment hole, which can be adjusted along the height direction of the vertical support 3 to fix the position.
[0051] By setting a detachable adjustment structure, the height of the fixing plate 40 can be adjusted according to the adapter plate of different thicknesses, thereby adjusting the distance between the pressure plate 42 and the limiting groove 20, ensuring that the contact pressure of the probe 421 is moderate when pressing down, ensuring both conductivity and no damage to the adapter plate; at the same time, for different models of adapter plates, the appropriate pressure plate can be quickly disassembled and replaced, such as pressure plates with different numbers and spacing of probes, so that the fixture can be compatible with testing of multiple specifications of adapter plates, solving the problem of poor compatibility in traditional manual testing.
[0052] Combination Figure 2 , Figure 3 As shown, the handle operation assembly 41 includes a fixed frame 411, a handle rod 412, a rotating rod 413, a hollow sleeve 414, and a central rod 415. The operator can drive the lower pressure plate 42 to rise and fall by moving the handle rod 412.
[0053] The fixing frame 411 is fixed to the middle of the fixing plate 40 by welding or bolts. A horizontal rotating shaft is provided at the upper end of the fixing frame 411. The handle rod 412 is rotatably connected to the fixing frame 411 through the rotating shaft. The handle rod can be moved up and down around the rotating shaft.
[0054] The hollow sleeve 414 is vertically fixed to the lower end of the fixing frame 411. The central rod 415 passes through the hollow sleeve 414 and can slide up and down along the axis of the hollow sleeve. The hollow sleeve guides the central rod to prevent it from shifting. The hollow sleeve 414 can be welded or integrally connected to the lower end of the fixing frame 411.
[0055] The rotating rod 413 has circular rotating connection holes at both ends. The handle rod 412 near the rotating shaft and the upper end of the middle rod 415 are both provided with pins that match the rotating connection holes. The rotating rod 413 is sleeved on the pins of the handle rod 412 and the middle rod 415 through the connection holes at both ends, forming a linkage structure of handle rod-rotating rod-middle rod.
[0056] When the handle 412 is pushed and rotated towards the vertical support, the handle 412 drives the middle rod 415 to slide down along the hollow sleeve 414 through the rotating rod 413, thereby pushing the lower pressure plate 42 to descend synchronously, so as to achieve contact between the probe and the test point of the adapter plate.
[0057] When the lever 412 is rotated away from the vertical support, the middle rod 415 slides upward with the rotating rod 413, and the lower pressure plate 42 rises and resets, completing the test point separation.
[0058] This linkage structure utilizes the lever principle, allowing operators to achieve stable raising and lowering of the lower pressure plate with only a small force. Compared to manually holding the probe and connecting the wires, the operational intensity is significantly reduced. At the same time, the guiding effect of the hollow sleeve ensures that there is no deviation during the raising and lowering of the middle rod, and the descent path of the lower pressure plate is precise, further ensuring the alignment accuracy between the probe and the test point and avoiding probe bending or test point damage due to the deviation of the lower pressure plate.
[0059] The lower pressure plate 42 is preferably a rectangular insulating plate, made of epoxy glass cloth, which has good insulation and high strength. Several probes 421 are fixed on its lower surface by welding or spring clips. The probes are made of gold-plated copper alloy, which has good conductivity and wear resistance. The number, position and spacing of the probes 421 are completely matched with the test points of the adapter board to be tested. The upper surface of the lower pressure plate 42 is fixedly connected to the connecting plate at the lower end of the middle rod 415 by bolts. The connecting plate is preferably made of metal and plays a role in force transmission.
[0060] When the pressure plate 42 descends under the drive of the middle rod 415, all probes 421 can simultaneously contact all test points of the adapter board. A single pressing action can complete the docking of dozens or even hundreds of test points. Compared with manual point-by-point wiring, it can realize batch and synchronous docking of test points, improve testing efficiency, greatly shorten the testing time of the adapter board, and fully meet the high-efficiency testing needs in mass production scenarios.
[0061] Example 4
[0062] This embodiment is a preferred implementation method based on Embodiment 1, Embodiment 2, or Embodiment 3, such as... Figure 1 As shown, the horizontal base 2 is also provided with an integrated connection port 22, such as a USB interface, a CAN bus interface or a dedicated aviation plug. The integrated connection port 22 is electrically connected to the test circuit through internal wires to realize the extended connection with the external system and expand the tooling function.
[0063] Integrated connection port 22 enables extended connections between the test fixture and external systems, such as:
[0064] When connected to a battery management system (BMS), the adapter board can be directly tested in actual working scenarios to simulate the connection performance of the BMS's power supply and signal transmission environment, making the test results more in line with actual application requirements and avoiding the performance deviation between traditional "offline testing" and "online use".
[0065] When connected to a computer or industrial control terminal, test data can be output through the port, such as the on / off status of each indicator light, test time, fault point number, etc., to realize the automatic recording, storage and statistical analysis of test results, which facilitates quality traceability and data management of the production line and further improves the level of intelligent testing.
[0066] Example 5
[0067] Based on the above embodiments, the complete testing steps of the adapter board testing fixture of this application are as follows:
[0068] Step 1, Fixture adaptation and adjustment: According to the specifications of the adapter board to be tested, select a matching pressure plate (probe quantity and position are adapted), install it on the vertical bracket 3 through the fixing plate 40, and adjust the height of the fixing plate to ensure that the probe can make normal contact with the test point when the pressure plate is lowered;
[0069] Step 2, Adapter plate positioning and installation: Place the adapter plate to be tested into the limiting groove 20 of the horizontal base 2, so that the limiting post 21 is inserted into the limiting hole of the adapter plate to complete the precise positioning of the adapter plate.
[0070] Step 3, Test point docking: Move the handle lever 412 to drive the lower pressure plate 42 to descend through the handle operation component 41 until the probe 421 is in stable contact with all test points of the adapter plate;
[0071] Step 4, Test Result Judgment: Turn on the power switch of the test circuit and observe the status of indicator light 23 on the horizontal base 2:
[0072] If all indicator lights 23 are lit, the adapter board is deemed qualified. Move the handle lever 412 upward to reset the lower pressure plate and remove the adapter board.
[0073] If indicator light 23 is not lit, record the fault test point number corresponding to the non-lit indicator light, determine the adapter board fault, remove it and proceed to the repair process;
[0074] Step 5, Batch Test Cycle: Repeat steps 2-4 to achieve continuous testing of multiple adapter boards.
[0075] The adapter board testing fixture of this embodiment, through the synergistic effect of the technical features in Embodiments 1, 2, 3, and 4, has the following significant advantages compared to the prior art:
[0076] ①High testing efficiency: The downward movement of the pressing plate of the pressing mechanism in a single operation allows the probes on the pressing plate to quickly complete the docking of all test points on the adapter plate, greatly shortening the testing time and improving the efficiency of batch testing;
[0077] ② High testing accuracy: Through the coordinated operation of the limiting groove structure and the pressing mechanism, the probe is precisely aligned with the test point. The elastic probe on the pressing plate provides stable contact pressure, and the indicator light provides intuitive judgment of the results, which greatly reduces the false detection rate and the missed detection rate, and improves the overall testing accuracy.
[0078] ③ Simple and safe operation: No highly skilled operators are required. Operators only need to complete the test in three steps: "place the adapter plate, operate the handle, and observe the indicator light". The entire process does not require holding the wires, avoiding the risk of electric shock and product damage.
[0079] ④ Functionality expandable: The integrated connection port can be connected to external systems such as BMS and computers to realize scenario-based testing and intelligent data management, meeting diverse testing needs.
[0080] In summary, the adapter board testing fixture of this application effectively solves the technical problems of "low efficiency, poor accuracy and complex operation" in the prior art. It can be widely used in batch testing scenarios of adapter boards in consumer electronics, industrial control, new energy and other fields, and has significant practical value and industrialization prospects.
