[0040] The embodiments of the present disclosure will be described below in conjunction with Figures 1 to 5 to introduce a test tool provided by the embodiments of the present disclosure.

[0041] According to the embodiments of the present disclosure, a test tool is provided for testing the insulation of a product to be tested 100, wherein, as shown in Figures 1 to 3 the test tool includes a base 10, an adjusting plate 20, a first conductive plate 30 and a second conductive plate 40, wherein the adjusting plate 20 is movably arranged on the base 10, the first conductive plate 30 is arranged on the base 10 as one electrode of the test tool, the second conductive plate 40 is connected with the adjusting plate 20 (for example, arranged on the lower surface of the adjusting plate 20) and faces the first conductive plate 30 as another electrode of the test tool. Among them, moving the adjusting plate 20 can adjust the distance between the first conductive plate 30 and the second conductive plate 40, so that a plurality of products to be tested 100 can be installed in parallel between the first conductive plate 30 and the second conductive plate 40.

[0042] According to the test tool provided by the embodiment of the utility model, by installing multiple products to be tested 100 in parallel between the first conductive plate 30 and the second conductive plate 40, the test tool can complete the insulation test of multiple products to be tested 100 at one time, and the test efficiency is higher, which can meet the demand of batch manufacturing.

[0043] As an example, in use, the adjusting plate 20 can be moved upwards to adjust the distance between the first conductive plate 30 and the second conductive plate 40, then multiple products to be tested 100 are installed in parallel between the first conductive plate 30 and the second conductive plate 40, and finally the adjusting plate 20 is moved downwards, which can conveniently position multiple products to be tested 100 between the first conductive plate 30 and the second conductive plate 40, so that the test tool can complete the insulation test of multiple products to be tested 100 at one time, the test speed is faster, which is convenient for batch test requirements, and the test efficiency is higher.

[0044] According to the application, when the product to be tested 100 is installed to the test tool, it can be connected with the external detection device. Specifically, the first conductive plate 30 of the test tool provides one electrode (end point) for insulation test, the second conductive plate 40 of the test tool faces the first conductive plate 30 and provides another electrode (end point) for insulation test, one end of the detection device is connected with the first conductive plate 30, and the other end is connected with the second conductive plate 40, so that the detection device and the first conductive plate 30 and the second conductive plate 40 form a test loop together. In the test process, the current passes through the product to be tested, and the insulation performance is measured. The detection device records the size of the current for subsequent analysis and judgment. If the size of the test current is very small (close to zero or much lower than the set threshold), it means that the current cannot pass through the product to be tested, and it can be judged that the product to be tested meets the insulation requirement, and the insulation test is passed. If the size of the test current is relatively obvious (higher than the set threshold), it means that the current can pass through the product to be tested, which may indicate that the insulation performance of the product to be tested has a problem. At this time, further test needs to be carried out on the batch of products to be tested. According to the embodiment of the application, the test tool can test the insulation performance of the product to be tested 100, and can be applied to batch test, and can also be suitable for products to be tested with different thicknesses or sizes, and has high test efficiency and universality.

[0045] According to the application, the adjusting plate 20 is movable, so that the distance between the first conductive plate 30 and the second conductive plate 40 of the test tool is adjustable. It can be understood that the first conductive plate 30 and the second conductive plate 40 have an adjustable test space, which makes the test tool more suitable for testing products of different sizes, increases the universality and flexibility of the test tool, and ensures the universality of the test tool. In addition, by adjusting the test space, good contact between the tested product and the conductive plate can be ensured, thereby improving the accuracy of the test result.

[0046] According to the present application, the "product under test 100" refers to a specific product that needs to be tested for insulation performance. As an example, the "product under test 100" can be a collector ring, a rubber product, etc. It should be noted that the specific type of "product under test 100" is not limited in this application, and those skilled in the art can apply the test tool to similar products as the exemplary embodiments of the present application under the teaching of the present application.

[0047] According to the present application, the first conductive plate 30 is connected to the base 10, and the first conductive plate 30 can be made of materials with good conductivity and corrosion resistance, such as copper, aluminum or stainless steel, etc. These materials not only have excellent conductivity, but also can resist corrosion that may occur during testing, ensuring long-term stability and accuracy of testing. In addition, the surface of the first conductive plate 30 can be flat or have appropriate grooves to accommodate different shapes and sizes of products under test. The flat surface is suitable for products with regular shape and small size; while the surface with grooves can better fix and support products with irregular shape or large size, ensuring the stability and accuracy of the products during testing. Similar to the first conductive plate 30, the second conductive plate 40 can also be made of materials with good conductivity and corrosion resistance to ensure the accuracy and long-term stability of the test. And also can have grooves and other features to facilitate the setting of the product under test.

[0048] According to the present application, the first conductive plate 30 is fixedly connected to the base 10, so that the connection is firm and reliable, and can ensure that there is no loosening or deformation during testing. As an example, the connection method can adopt bolt connection, welding or buckle connection, etc. The specific choice should be determined according to the actual situation and use requirements. Similar to the first conductive plate 30, the second conductive plate 40 can also be fixedly connected to the adjusting plate 20 to ensure the reliability during testing. It should be noted that the first conductive plate 30 and the second conductive plate 40 according to the present application can also be detachably connected to the corresponding parts, so that the first conductive plate 30 and the second conductive plate 40 can be replaced according to actual needs to meet more testing needs and improve the versatility of the product.

[0049] In some embodiments, a plurality of first mounting grooves and second mounting grooves are respectively provided on the first conductive plate 30 and the second conductive plate 40, so that the positioning and installation of the product under test 100 can be facilitated, and the accuracy and efficiency of the test can be improved.

[0050] As an example, as shown in FIG. 1, Figure 2 , Figure 4 and Figure 5As shown, the first conductive plate 30 is provided with a plurality of first mounting slots 31, and the second conductive plate 40 is provided with a plurality of second mounting slots 41. The plurality of first mounting slots 31 respectively face the plurality of second mounting slots 41. The two ends of the product 100 to be tested can be respectively embedded in a pair of first mounting slots 31 and second mounting slots 41 that face each other, that is, the plurality of first mounting slots 31 are used to accommodate one end of the product 100 to be tested, and the plurality of second mounting slots 41 correspond to the first mounting slots 31 and are used to accommodate the other end of the product to be tested.

[0051] In the embodiments of the present application, the size of the mounting slot can be determined according to the size and shape of the product 100 to be tested. In this way, it can be ensured that the mounting slot can tightly accommodate and fix the product 100 to be tested, so that the test tool can be suitable for a plurality of different types of products to be tested, and the versatility and flexibility of the test are improved. As an example, the product to be tested is cylindrical, and the cross section of the mounting slot can be a circle with a diameter of 5-10 cm.

[0052] In these embodiments, by respectively providing the first mounting slots 31 and the second mounting slots 41 on the first conductive plate 30 and the second conductive plate 40, the mounting slots can enable the product 100 to be tested to be quickly positioned and installed, shorten the preparation time of the test, and further improve the test efficiency. In addition, the mounting slots that face each other can improve the stability of the installation of the product 100 to be tested, so as to ensure the stability and consistency during the test, reduce the test error, and improve the accuracy of the test. In addition, the arrangement of the mounting slots also helps to protect the edges and connecting parts of the product 100 to be tested, avoiding damage during the test.

[0053] In some embodiments, the plurality of first mounting slots 31 and the plurality of second mounting slots 41 are respectively arranged in an array. Here, the array arrangement refers to arranging a plurality of first mounting slots and second mounting slots in a regular manner into rows and columns. The plurality of first mounting slots 31 and the plurality of second mounting slots 41 are respectively arranged in an array, so that the arrangement of the mounting slots is more neat, which can ensure the structural beauty of the test tool. In addition, the neat arrangement facilitates the adjacent mounting slots to have a suitable spacing, avoiding interference between the products to be tested during installation, and also facilitates the user to quickly position and install. In addition, the array arrangement can make full use of the available space on each conductive plate, and more mounting slots can be easily arranged to install the product to be tested, which can further improve the test efficiency.

[0054] In some embodiments, the adjusting plate 20 is provided with a through hole 23, and the second mounting slot 41 is opposite to and communicates with the through hole 23.

[0055] As an example, each mounting slot is correspondingly provided with a through hole 23 above the mounting slot, so that the overall strength of the adjusting plate 20 can be ensured without affecting the accuracy of the test. In this way, the stability and reliability of the structure can be ensured while meeting the functional requirements. It should be noted that the embodiments of the present application are not limited thereto, and those skilled in the art can adjust the form of the through hole 23 on the adjusting plate 20 under the teaching of the present application, for example, two or more mounting slots can be provided with one through hole 23. In addition, by opening the through hole 23 on the adjusting plate 20 and being opposite and communicating with the second mounting slot 41, when the product to be tested 100 is placed between the first conductive plate 30 and the second conductive plate 40, the through hole 23 on the adjusting plate 20 corresponding to the mounting slot can facilitate the installation of the product to be tested 100, simplify the installation method, and improve the installation efficiency.

[0056] According to the present application, the base 10 as the supporting structure of the test tool can ensure the stability of the test tool and the stability and accuracy of each component during the test.

[0057] In some embodiments, the base 10 includes a bottom plate 11 and a plurality of connecting guide columns 12, wherein the bottom plate 11 can serve as a supporting part of the test tool and provide a mounting site for the first conductive plate 30. As an example, the first conductive plate 30 is arranged on the bottom plate 11, for example, mounted on the upper surface of the bottom plate 11. The plurality of connecting guide columns 12 extend upward from the bottom plate 11 and connect the adjusting plate 20 to provide stable support and guidance for the adjusting plate 20. As an example, the plurality of connecting guide columns 12 are connected to the upper surface of the bottom plate 11. In the case where the connecting guide columns 12 are made of metal material, the plurality of connecting guide columns 12 are arranged at positions separated from the first conductive plate 30 to avoid contact with the first conductive plate 30. The adjusting plate 20 is movably arranged on the plurality of connecting guide columns 12, so that the user can adjust the distance between the first conductive plate 30 and the second conductive plate 40 as needed, so that a plurality of products to be tested 100 can be installed in parallel between the first conductive plate 30 and the second conductive plate 40, and can adapt to different sizes or types of products to be tested 100.

[0058] As an example, the connecting guide column 12 can be an optical axis, which as a guiding component can ensure that the adjusting plate 20 moves smoothly in the vertical direction. In addition, the optical axis has low friction resistance and small wear, which can improve the stability and service life of the test tool.

[0059] As an example, the number of connecting guide columns 12 can be at least three, so that the adjusting plate 20 moving thereon can have higher stability, while a reasonable number of connecting guide columns 12 will not occupy too much space and will not hinder the installation and testing of the product to be tested 100.

[0060] In some embodiments, the test tool further comprises a plurality of locking devices 50 respectively arranged on the corresponding connecting columns 12, for locking the adjusting plate 20 on the connecting columns 12.

[0061] In these embodiments, the locking devices 50 are respectively arranged on the corresponding connecting columns 12, for locking the adjusting plate 20 on the connecting columns 12 at a specific position, so as to ensure that the adjusting plate 20 will not be accidentally moved due to external force (such as vibration, impact, etc.) during the test process, thereby ensuring the stability of the test process and the accuracy of the test result.

[0062] In use, the height of the adjusting plate 20 can be adjusted according to the size and type of the product 100 to be tested, so that the distance between the first conductive plate 30 and the second conductive plate 40 is moderate. Then, the adjusting plate 20 is locked by the locking device to maintain the distance between the two. Then, the product 100 to be tested is installed on the first conductive plate 30 to fix the lower end of the product 100 to be tested. Subsequently, the locking device 50 is unlocked to release the adjusting plate 20, and the second conductive plate 40 can fix the upper end of the product 100 to be tested, so that the two ends of the product to be tested can be fixed on the first conductive plate 30 and the second conductive plate 40 respectively, facilitating the fixing operation of the product to be tested. In addition, during use, since the locking device is provided, the operator can complete the fixing and unlocking operations of the adjusting plate 20 alone without the assistance of others, greatly reducing the number of required operators and improving the operation efficiency and flexibility of the test tool.

[0063] In some embodiments, the locking device 50 is a locking linear bearing, which is sleeved on the connecting column 12, can move in the length direction of the connecting column 12, and can be selectively locked at any position in the length direction of the connecting column 12. The adjusting plate 20 is installed on the locking linear bearing, and it can be understood that the locking linear bearing serves as a support and locking mechanism for the adjusting plate 20. In the embodiments of the present application, a commercially available locking linear bearing can be selected.

[0064] In these embodiments, the locking linear bearing can provide sliding support, specifically, in use, the locking linear bearing can move freely in the length direction of the connecting guide column 12, so that the operator can easily adjust the height of the adjustment plate 20 to adapt to different sizes or types of products to be tested. The locking linear bearing also has a locking function, which can lock at any position in the length direction of the connecting guide column 12, thereby fixing the position of the adjustment plate 20, so as to ensure the stability of the adjustment plate 20 during testing and prevent accidental movement due to external forces such as vibration, impact, etc. Because the locking linear bearing realizes the functions of height adjustment and locking, the operator can quickly and accurately adjust the height of the adjustment plate 20 and fix it at the desired position. This will greatly shorten the preparation time of the test and improve the test efficiency. In addition, the operator can easily move the locking linear bearing to adjust the height of the adjustment plate 20 and fix it at the desired position through the locking mechanism, which facilitates one-handed operation, making it easier for the operator to adjust the height and lock the position.

[0065] In some embodiments, the first conductive plate 30 and the second conductive plate 40 are both metal plates, and during testing, the first conductive plate 30 and the second conductive plate 40 need to be connected to the detection device through wires or clamps. Because the metal plate has good electrical conductivity, when the detection device is connected to the first conductive plate 30 and the second conductive plate 40, the detection device can transmit current through these two conductive plates, thereby achieving the purpose of testing insulation performance. At the same time, the metal plate also has the advantages of high mechanical strength, good corrosion resistance, easy processing and manufacturing, etc., which can meet other needs during testing.

[0066] In some embodiments, the adjustment plate 20 is provided with a handle 60 for holding to move the adjustment plate 20. The handle 60 is provided to make it easy for the operator to move or adjust the position of the adjustment plate 20, especially when frequent adjustments are needed, which can significantly improve the convenience of operation.

[0067] As an example, the handle can be provided in the middle region of the adjustment plate 20, formed in a concave shape, and have an arc that conforms to the principles of ergonomics, which can reduce hand fatigue and discomfort for the operator during long-term use.

[0068] In some embodiments, the base is an insulating base, which can prevent current from being transmitted to the ground through the base, so as to ensure the safety of the tester and the normal operation of the detection device in the case of excessively high voltage.

[0069] According to the present application, the adjusting plate 20 is movably arranged on the base 10, and by moving the adjusting plate 20, the distance between the first conductive plate 30 and the second conductive plate 40 can be conveniently adjusted. This makes the test tool flexible to adapt to products 100 of different thicknesses or sizes, and has universality and convenience.

[0070] In some embodiments, the adjusting plate 20 includes a metal plate 21 and an insulating pad 22, the metal plate 21 is movably arranged on the base 10, and the insulating pad 22 is connected between the metal plate 21 and the second conductive plate 40, for isolating the metal plate 21 and the second conductive plate 40.

[0071] As an example, the metal plate 21 can be made of a high-strength material, for example, made of a metal material with high strength, good mechanical properties and corrosion resistance, so that the metal plate 21 can withstand a large load and maintain the stability and reliability of the structure in long-term use. The insulating pad 22 can be made of a material with high insulation resistance and low dielectric constant, such as rubber, plastic or ceramic, etc. These materials can effectively prevent the passage of current while reducing electromagnetic interference and leakage. It should be noted that the present application does not make too many limitations, and those skilled in the art can select other suitable materials to form the structure of the adjusting plate according to the teachings of the present application.

[0072] In these embodiments, the metal plate 21 serves as the main structure of the adjusting plate 20 and has reliable strength, and it is movably arranged on the base 10 and can be moved away from or close to the base 10 as needed to meet the testing requirements, ensuring the stability and durability of the entire adjusting plate during testing.

[0073] Although the metal plate 21 has many advantages (strength, corrosion resistance), its electrical conductivity has become a potential safety hazard. During the insulation test, if the metal plate 21 is in direct contact with the second conductive plate 40, it may cause current leakage or short circuit, thereby affecting the accuracy and safety of the test. Therefore, the insulating pad 22 is connected between the metal plate 21 and the second conductive plate 40, here, the insulating pad 22 serves as an electrical isolation layer and can effectively separate the metal plate 21 and the second conductive plate 40, so that the current can only pass through the product to be tested according to the predetermined path during testing, thereby improving the accuracy and safety of the test. In addition, by introducing the insulating pad 22, the safety of the test tool can be guaranteed. Especially in the case of high voltage, the insulating pad 22 can effectively prevent the passage of current, thereby protecting the safety of the test personnel and the detection equipment.

[0074] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that these modifications and variations will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
