Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a testing tooling and testing equipment. Background Technology

[0002] Currently, most existing current sensor products are single-channel or multi-channel current components. These sensors do not contain an internal copper busbar structure; instead, current transmission is achieved through external connections. Although mounting holes for the copper busbar are provided, in some cases, users may require additional tools or expertise to correctly install it, increasing the time and difficulty of initial setup. Because the sensor housing has pre-drilled mounting holes for the copper busbar, the sensor's performance and reliability depend to some extent on the quality and installation process of the external copper busbar, thus increasing assembly complexity and dependence on external components.

[0033] This utility model proposes a testing fixture and testing equipment.

[0034] Reference Figures 1-2 In this embodiment of the present invention, a testing fixture includes:

[0035] Upper mold 10, wherein the upper mold 10 is provided with a first connector 11;

[0036] The lower mold 20 has a test sample between the upper mold 10 and the lower mold 20. The lower mold 20 has a second connector 21. The power supply interface of the second connector 21 is electrically connected to a power source. The power source supplies power to the second connector 21 to provide current to the detection structure on the test sample.

[0037] A driving component is connected to the upper mold 10 to drive the upper mold 10 to move in the vertical direction, so as to press down onto or away from the lower mold 20;

[0038] When the upper mold 10 is pressed down onto the lower mold 20, the first connector 11 and the second connector 21 form a detection link, and the power supply provides power to the detection link for detecting the test item.

[0039] This application describes a device for testing fixtures (used for quality control or product testing in industrial production). Its main components are an upper mold 10, which is part of the testing fixture and is capable of vertical movement to engage with a lower mold 20 to clamp the test object (DUT). The upper mold 10 has a first connector 11 responsible for forming contact with one side of the DUT. The lower mold 20, the other half paired with the upper mold 10, supports the DUT. A second connector 21, whose power supply interface is connected to a power source, provides power to the entire testing circuit, ensuring its proper functioning. The detection structure receives power from the connectors and uses this power to detect the DUT placed between the upper mold 10 and the lower mold 20. A drive unit connected to the upper mold 10 provides power to move the upper mold vertically. This allows the upper mold to move closer to the lower mold to clamp the DUT for detection, or away from the lower mold to insert or remove the DUT. When the upper mold 10 is pressed down by the drive unit onto the lower mold 20, the first connector 11 and the second connector 21 together form a complete detection link, allowing current to flow through the DUT, thereby enabling electrical performance testing. Understandably, the sample to be tested is first placed on the lower mold 20. The second connector 21 is connected to an external power source via a power supply interface to provide the necessary power to the test sample. The movement of the upper mold 10 is controlled by a drive mechanism (e.g., a cylinder, hydraulic cylinder, or electric motor). The drive mechanism can receive signals from a control system (not mentioned). The drive mechanism moves the upper mold 10 downwards until the first connector 11 is in complete contact with the test sample and the second connector 21, forming a closed detection link. At this point, if the test sample is a circuit board or other components that require contact for testing, once the detection link is established, the power supply begins, and current flows through the test sample. The functional status of the test sample can then be evaluated by monitoring voltage, resistance, or other parameters. After the test is completed, the drive mechanism moves again, lifting the upper mold 10 upwards, disconnecting the detection link, removing the tested sample, and preparing for the next test. This scheme uses a drive mechanism to achieve automatic opening and closing of the upper and lower molds, improving testing efficiency, reducing human intervention, and increasing the consistency and accuracy of test results. Through mechanical positioning and connector design, the detection link is accurately established for each test, ensuring the consistency of measurement conditions. The separate power connection (i.e., power is connected only to the lower die) helps reduce potential safety risks and protect operators and equipment. This design allows for adjustments to the connector layout on the upper die 10 and lower die 20 to accommodate various testing needs based on different types of test pieces. Stable electrical connections ensure stable current transmission during testing, improving the reliability of test data.

[0040] Reference Figures 1-2In this embodiment of the present invention, the second connector 21 is a plurality of first terminal block assemblies 22, which are spaced apart along a first direction. Each first terminal block assembly 22 is provided with an inlet end and an outlet end. The inlet end and the outlet end are connected by a wire between two adjacent first terminal block assemblies 22. The power input end of any first terminal block assembly 22 is used to be electrically connected to a power source to provide current for testing the test object.

[0041] The second connector 21 consists of multiple first terminal block assemblies 22, with adjacent first terminal block assemblies 22 connected by wires to their input and output terminals. This structure effectively forms a series connection. Current flows sequentially from the power source through each terminal block assembly, forming a continuous path. In a series circuit, the current across all components is the same. The total voltage is distributed across all components; that is, the sum of the voltages across each terminal block assembly equals the total voltage supplied by the power source. The presence of multiple first terminal block assemblies 22 means that multiple electrical connection points can be established simultaneously at different locations on the device under test (DUT). This is extremely useful for complex circuit boards that require current injection or voltage measurement at multiple points. Since any terminal block assembly can serve as a power input, this provides great flexibility, allowing the selection of the most suitable terminal block assembly to connect to the power source based on actual needs, optimizing the current path. If some terminal block assemblies fail, the others can continue to operate, ensuring the reliability and continuity of the system. The design of multiple first terminal block assemblies 22 helps to distribute current more evenly across the DUT, reducing the possibility of localized current overload and thus improving the accuracy of test results. Specifically, the device under test (DUT) is placed at a designated position between the upper mold 10 and the lower mold 20. One or more first terminal assemblies 22 are selected, and their power inputs are connected to an external power source, ensuring that the power supply can power the entire circuit. The actuator moves the upper mold 10 downwards until it contacts the lower mold 20, at which point the first connector 11 (located in the upper mold) and the multiple first terminal assemblies 22 (located in the lower mold) form a complete electrical connection path, i.e., a detection link. Once the detection link is established, the power supply applies current to the DUT through the selected first terminal assembly 22. The current characteristics flowing through the DUT are recorded, and the functionality and quality of the DUT are evaluated based on this information. After the test is completed, the actuator moves the upper mold 10 away from the lower mold 20, disconnects the electrical connection, removes the DUT, and repeats the above process to test the next sample. It is understood that the first terminal assembly 22 can be a copper busbar as part of the terminal, exposed for mating with external wires or terminals on the other side, simplifying the structure, reducing the number of additional components, and improving integration. It is necessary to ensure that the surface of the copper busbar is flat and smooth to avoid oxidation or contamination affecting electrical contact. At the same time, additional fixing devices may be required to ensure the accurate positioning of the copper busbar. Embedded copper busbars can also be used, where the copper busbar can be embedded in the lower mold or other structures, exposing only the necessary contact surfaces as terminals. Alternatively, a modular design can be used, where the copper busbar is combined with other types of terminals (such as bolt-type, spring clip-type, etc.) to form a hybrid structure, which combines the high conductivity of the copper busbar with the ease of operation of other terminals, providing better performance and user experience.

[0042] Reference Figures 1-2In this embodiment of the present invention, the plurality of first terminal assembly 22 includes at least a first terminal assembly 211, a second terminal assembly 212, and a third terminal assembly 213. The first terminal assembly 211 includes a first terminal 2111 and a second terminal 2112. The second terminal assembly 212 includes a third terminal 2121 and a fourth terminal 2122. The third terminal assembly 213 includes a fifth terminal 2131 and a sixth terminal 2132. The first terminal 2111, the third terminal 2121, and the fifth terminal 2131 are spaced apart on the same side of the lower mold 20. The second terminal 2112, the fourth terminal 2122, and the sixth terminal 2132 are spaced apart on the other side of the lower mold 20. The first terminal 2111 and the third terminal 2121 are electrically connected. The second terminal 2112 and the fifth terminal 2131 are electrically connected. The fourth terminal 2122 and the sixth terminal 2132 are electrically connected.

[0043] The lower mold 20 has a first terminal 2111, a third terminal 2121, and a fifth terminal 2131 on one side; and a second terminal 2112, a fourth terminal 2122, and a sixth terminal 2132 on the other side. This layout ensures that current can flow from one side to the other. The current flows along a specific path, entering from the terminals on one side, passing through the test object, and then exiting from the corresponding terminals on the other side, forming a closed circuit. The connection relationship between the two terminals within each terminal assembly (211, 212, 213) ensures that the current can flow smoothly throughout the entire detection link. This design allows for more precise control of the current path, thereby improving detection accuracy. Furthermore, by adjusting the electrical connection between different terminals, it can accommodate test objects of different types or sizes, increasing the system's flexibility and applicability. Specifically, the current enters from the first terminal 2111, where the positive terminal of the power supply is connected, and the current begins to flow in. Current enters the device under test (DUT) through the contact point between the first connector 11 of the upper mold 10 and the first terminal 2111 on the lower mold 20. Reaching the second terminal 2112, the current flows through the DUT and exits from the other side, returning to the second terminal 2112. From the second terminal 2112 to the fifth terminal 2131, according to electrical connection rules, the current is transferred directly or indirectly (through internal circuitry) from the second terminal 2112 to the fifth terminal 2131. Flowing through the third terminal assembly 213, the current again passes through the DUT, entering from one side of the fifth terminal 2131 and then exiting from the sixth terminal 2132. From the sixth terminal 2132 to the fourth terminal 2122, according to electrical connection rules, the current is transferred from the sixth terminal 2132 to the fourth terminal 2122. Flowing through the second terminal assembly 212, the current continues through the DUT, entering from one side of the fourth terminal 2122 and then exiting from the third terminal 2121. Returning to the first terminal 2111, the current finally flows from the third terminal 2121 back to the first terminal 2111, forming a closed loop.

[0044] Reference Figures 1-2 In this embodiment of the present invention, the first connector 11 is a plurality of second terminal block assemblies 111, the plurality of second terminal block assemblies 111 are spaced apart along the first direction, and the plurality of second terminal block assemblies 111 are arranged in a one-to-one correspondence with the plurality of first terminal block assemblies 22.

[0045] Specifically, the first connector 11 consists of multiple second terminal block assemblies 111, which correspond one-to-one with multiple first terminal block assemblies 22 on the lower mold 20. This design ensures that each test point has an independent current path and allows for more precise control and monitoring of current flow. The first connector 11 of the upper mold 10 contains multiple second terminal block assemblies 111, which are spaced apart in the same direction and correspond one-to-one with multiple first terminal block assemblies 22 on the lower mold 20. This means that each second terminal block assembly 111 is specifically responsible for forming a pair of contacts with a specific first terminal block assembly 22, thereby providing independent detection links for different parts of the test object. Because a one-to-one relationship is formed between each second terminal block assembly 111 and its corresponding first terminal block assembly 22, current can flow from one terminal to another without being confused or interfering with other current paths. This design improves test accuracy and simplifies the troubleshooting process. The one-to-one terminal block assembly design allows for independent current supply and monitoring for each test point, reducing mutual influence between different test points and improving the accuracy of test results. When a problem occurs at a test point, the issue can be quickly located by checking the corresponding terminal block assembly, eliminating the need to check other locations one by one, saving time and effort. This modular design allows for adjustments to the number and layout of terminal block assemblies based on different test objects, adapting to more diverse testing needs. Since each test link is independent, even if one link experiences a short circuit or other fault, it will not affect the operation of other links, reducing overall system risk. Understandably, the second terminal block assembly 12 can be a copper busbar directly as part of the terminal block, exposed for mating with external wires or terminals on the other side, simplifying the structure, reducing the number of additional components, and improving integration. It is necessary to ensure the copper busbar surface is flat and smooth to avoid oxidation or contamination affecting electrical contact; additional fixing devices may be needed to ensure accurate positioning of the copper busbar; alternatively, it can be an embedded copper busbar, embedded within the lower mold or other structure, exposing only the necessary contact surface as a terminal block; or it can be a combined design, using the copper busbar in conjunction with other types of terminals (such as bolt-type, spring-clip type, etc.) to form a hybrid structure, combining the high conductivity of the copper busbar with the ease of operation of other terminals, providing better performance and user experience.

[0046] Reference Figures 1-2In this embodiment of the present invention, the plurality of second terminal assembly 12 includes at least a fourth terminal assembly 111, a fifth terminal assembly 112, and a sixth terminal assembly 113. The fourth terminal assembly 111 includes a seventh terminal 1111 and an eighth terminal 1112. The fifth terminal assembly 112 includes a ninth terminal 1121 and a tenth terminal 1122. The sixth terminal assembly 113 includes an eleventh terminal 1131 and a twelfth terminal 1132. The seventh terminal 111... 11. The ninth terminal 1121 and the eleventh terminal 1131 are spaced apart on the same side of the upper mold 10, and the eighth terminal 1112, the tenth terminal 1122 and the twelfth terminal 1132 are spaced apart on the other side of the upper mold 10. The seventh terminal 1111 and the ninth terminal 1121 are electrically connected, the eighth terminal 1112 and the eleventh terminal 1131 are electrically connected, and the tenth terminal 1122 and the twelfth terminal 1132 are electrically connected.

[0047] One side of the upper mold 10 has a seventh terminal 1111, a ninth terminal 1121, and an eleventh terminal 1131. The other side of the upper mold 10 has an eighth terminal 1112, a tenth terminal 1122, and a twelfth terminal 1132. This layout ensures that current can flow from one side to the other. The current flows along a specific path, entering from the terminals on one side, passing through the test object, and then exiting from the corresponding terminals on the other side, forming a closed circuit. The connection relationship between the two terminals within each terminal assembly (111, 112, 113) ensures that the current can flow smoothly throughout the entire detection link. This design allows for more precise control of the current path, thereby improving detection accuracy. Furthermore, by adjusting the electrical connections between different terminals, it can accommodate test objects of different types or sizes, increasing the system's flexibility and applicability. Specifically, the power supply is connected to the seventh terminal 1111 in the fourth terminal assembly 111 (as the positive input). The current flow is as follows: it enters from the seventh terminal 1111, where the positive terminal of the power supply is connected, and the current begins to flow in. The current enters the test object (DUT) through the contact point between the first connector 11 of the upper mold 10 and the corresponding first terminal assembly 22 on the lower mold 20. Reaching the ninth terminal 1121, according to electrical connection rules, the current is transferred from the seventh terminal 1111 to the ninth terminal 1121. Flowing through the fifth terminal assembly 112, the current again passes through the DUT, entering from one side of the ninth terminal 1121 and then exiting from the tenth terminal 1122. From the tenth terminal 1122 to the twelfth terminal 1132, according to electrical connection rules, the current is transferred from the tenth terminal 1122 to the twelfth terminal 1132. The current flows through the sixth terminal assembly 113, continues through the device under test (DUT), enters from the twelfth terminal 1132, and exits from the eleventh terminal 1131. Returning to the eighth terminal 1112, according to electrical connection rules, the current flows from the eleventh terminal 1131 back to the eighth terminal 1112. Finally, the current returns from the eighth terminal 1112 to the negative power supply or ground, forming a complete closed loop.

[0048] Reference Figures 1-2 In this embodiment of the present invention, a guide structure 30 for vertical movement of the upper mold 10 is connected between the upper mold 10 and the lower mold 20.

[0049] A guide structure 30 connects the upper mold 10 and the lower mold 20 for the vertical movement of the upper mold 10. This design ensures that the upper mold 10 can be stably and accurately positioned during vertical movement, and avoids unnecessary lateral displacement or tilting, thereby improving the accuracy and reliability of the test. It is understood that the guide structure 30 can consist of a guide rail, a slider, or other form of guiding device, installed between the upper mold 10 and the lower mold 20, or directly fixed to the frame of the test fixture. Its main function is to guide the upper mold 10 to move smoothly in the vertical direction, ensuring consistency in the contact position each time. The guide structure 30 works in conjunction with the driving components (such as cylinders, electric push rods, etc.) to enable the upper mold 10 to complete downward pressing or upward lifting actions under precise control. The guide structure 30 ensures the accurate vertical positioning of the upper mold 10, reducing the risk of lateral displacement or tilting, thereby improving the accuracy of contact at each test point. With the support of the guide structure 30, the upper mold 10 is more stable during movement, avoiding errors caused by vibration or other external factors, and ensuring the reliability of the test results. A stable motion trajectory reduces friction and wear between mechanical parts, which helps extend the overall service life of the equipment and lowers maintenance costs.

[0050] Reference Figures 1-2 In this embodiment of the present invention, the guide structure 30 includes a plurality of guide posts and a plurality of limiting holes. The plurality of limiting holes are disposed on the lower mold 20, and the plurality of guide posts are disposed on the upper mold 10. The plurality of guide posts are adapted to the plurality of limiting holes.

[0051] Multiple limiting holes are provided on the lower mold 20 to provide precise positioning and restraint for the guide pillars of the upper mold 10, ensuring accurate alignment each time the upper mold 10 descends. Multiple guide pillars are mounted on the upper mold 10, passing through corresponding limiting holes, ensuring that the upper mold 10 can only move vertically, avoiding lateral displacement or tilting. The guide pillars work in conjunction with driving components (such as cylinders, electric push rods, etc.) to enable the upper mold 10 to perform downward pressing or upward lifting actions under precise control. The cooperation of multiple limiting holes and guide pillars ensures accurate vertical positioning of the upper mold 10, reducing the risk of lateral displacement or tilting, thereby improving the accuracy of contact at each test point. Supported by multiple guide pillars, the upper mold 10 is more stable during movement, avoiding errors caused by vibration or other external factors, and ensuring the reliability of test results. The stable motion trajectory reduces friction and wear between mechanical parts, helping to extend the overall service life of the equipment and reduce maintenance costs. The cooperation of multiple guide pillars and limiting holes makes the movement of the upper mold 10 more automated and controllable, reducing the need for manual intervention and improving work efficiency.

[0052] Reference Figures 1-2In this embodiment of the present invention, the testing fixture further includes a switch, which corresponds to the working position of the lower mold 20.

[0053] The test fixture also includes a switch corresponding to the working position of the lower mold 20. This design ensures that the circuit closes, thus initiating the test process, only when the upper mold 10 and lower mold 20 are correctly aligned and in their working positions. Understandably, the switch is mounted on or near the lower mold 20, corresponding to its working position. When the upper mold 10 descends and fully contacts the lower mold 20, the switch is triggered to close the circuit. The switch can be mechanical (e.g., a microswitch), photoelectric (e.g., a photoelectric sensor), or other types of sensors to detect whether the upper mold 10 has reached the predetermined working position. The switch can also serve as part of a safety interlock, ensuring that operations such as power supply or data acquisition are only performed in the correct position, preventing misoperation or unsafe operating conditions.

[0054] Reference Figures 1-2 In this embodiment of the present invention, the testing fixture further includes a display screen, which is connected to the upper mold 10.

[0055] The testing fixture also includes a display screen connected to the upper mold 10.
