[0045] The following combination Figures 1 to 6 The tooling 100 and testing equipment provided in the embodiments of this application will be described in detail.

[0046] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the tooling 100 provided in an embodiment of this application. Figure 2 This is an exploded view of tooling 100 provided in an embodiment of this application. Figure 3 yes Figure 1 Sectional view of AA, Figure 4 yes Figure 3 Enlarged structural diagram at point B. Figure 5 This is a schematic diagram of the structure for testing the insulation withstand voltage performance of sample 41 according to an embodiment of this application. In a first aspect, an embodiment of this application provides a fixture 100. The fixture 100 includes a first insulating shell 11, a second insulating shell 12, a first conductive element 21, and a second conductive element 22. The first insulating shell 11 has a first wiring hole 111. The second insulating shell 12 is detachably connected to the first insulating shell 11. The second insulating shell 12 has a second wiring hole 121. The first wiring hole 111 and the second wiring hole 121 communicate with each other. The first conductive element 21 is disposed in the first wiring hole 111. The second conductive element 22 is disposed in the second wiring hole 121. The first conductive element 21 and the second conductive element 22 are spaced apart to form a sample mounting cavity 40.

[0047] The first insulating shell 11 can be located above the second insulating shell 12. Correspondingly, the first conductive element 21 can be inserted into the first wiring hole 111 and engage with the hole wall of the first wiring hole 111 in a direction away from the second insulating shell 12, so that after the first insulating shell 11 and the second insulating shell 12 are engaged, the first conductive element 21 can press the sample 41 onto the second conductive element 22. Alternatively, the first conductive element 21 can be glued into the first wiring hole 111 to fix it relative to the first insulating shell 11, so that after the first insulating shell 11 and the second insulating shell 12 are engaged, the first conductive element 21 can press the sample 41 onto the second conductive element 22.

[0048] Additionally, the second insulating shell 12 can be located below the first insulating shell 11. Correspondingly, one end of the second wiring hole 121 faces the first insulating shell 11, and the other end communicates with the side wall of the second insulating shell 12. In this way, the second insulating shell 12 can support the second conductive element 22, so that after the first insulating shell 11 and the second insulating shell 12 are engaged, the second insulating shell 12 can restrict the movement of the sample 41 and the second conductive element 22, allowing the first conductive element 21 to press the sample 41 tightly onto the second conductive element 22.

[0049] Specifically, the first conductive element 21 is attached to the inner wall of the first wire hole, and the second conductive element 22 is attached to the inner wall of the second wire hole.

[0050] It is understood that the first insulating shell 11 and the second insulating shell 12 are made of rigid plastics with insulating properties, such as phenolic resin, epoxy resin, silicone resin, polypropylene, etc.

[0051] It is understood that the first conductive component 21 and the second conductive component 22 are made of materials with good electrical conductivity, such as copper, aluminum, graphite, etc.

[0052] The insulating sample 41, used for testing the insulation withstand voltage performance, is placed inside the sample mounting cavity 40, such as... Figure 5 As shown.

[0053] Specifically, the first conductive element 21 and the second conductive element 22 are connected to the positive and negative terminals of the high-voltage power supply, respectively. When testing the insulation withstand voltage performance of the sample 41, the sample 41 is first placed in the mounting cavity, and then energized, thus placing the sample 41 in a high-voltage circuit. Simultaneously, the voltage applied to the sample 41 can be determined using a voltmeter, and the presence or absence of leakage current can be monitored using an ammeter to determine whether the sample 41 has been broken down (e.g., a sudden increase in current indicates insulation failure of the sample 41). A timer can also be used to determine the duration of high voltage withstand by the sample 41.

[0054] In this embodiment, by providing a first insulating shell 11 and a second insulating shell 12 to cover the sample 41 to be tested and the first conductive component 21 and the second conductive component 22 connected to the sample 41, the insulation isolation between the high-voltage circuit and the operator during the testing process can be improved, thereby enhancing the safety protection of the fixture 100. This reduces safety risks during the testing process, thus improving the safety of the operator.

[0055] In addition, the first conductive element 21 and the second conductive element 22 are respectively mounted on the first insulating shell 11 and the second insulating shell 12, so that the required structure and size of the first conductive element 21 and the second conductive element 22 can be selected according to different products, which helps to expand the applicability of the tooling 100 and thus meet the electrical connection requirements of different types of insulation withstand voltage test equipment.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the first conductive element 21 includes a conductive post 211 and a conductive foam 212. Both the conductive post 211 and the conductive foam 212 are disposed within the first wiring hole 111. The conductive post 211 is in contact with the conductive foam 212. The conductive foam 212 is located between the conductive post 211 and the sample mounting cavity 40. The surface area of ​​the conductive foam 212 facing the sample mounting cavity 40 is larger than the surface area of ​​the conductive post 211 facing the sample mounting cavity 40.

[0057] It is understandable that conductive foam 212 combines the flexibility and conductivity of foam materials by incorporating conductive substances (such as metal plating, metal powder, carbon fiber, etc.) into foam materials (such as polyurethane, polyethylene, etc.).

[0058] In this embodiment, by providing conductive foam 212, firstly, it can buffer the direct contact between the conductive post 211 and the sample, thereby protecting the integrity of the sample's surface structure and improving the accuracy of the insulation withstand voltage test results. Secondly, by increasing the size of the conductive foam 212 while controlling the size of the conductive post 211, the contact area between the first conductive element 21 and the sample 41 can be increased, thereby improving the reliability of the electrical contact between the first conductive element 21 and the sample 41 and improving their overcurrent capacity.

[0059] In addition, the conductive post 211 is connected to the high-voltage test rod. Specifically, the end of the conductive post 211 away from the conductive foam 212 is provided with a tapered hole 2111 for insertion into the end of the high-voltage test rod.

[0060] Please see Figure 2 and Figure 4 In some embodiments, the tooling 100 further includes an insulating sheet 23. The insulating sheet 23 is located between the conductive post 211 and the second conductive element 22. The insulating sheet 23 is circumferentially disposed around the conductive foam 212. One side of the insulating sheet 23 contacts the second conductive element 22. The conductive foam 212 is configured to be compressed and integrally located within the inner hole of the insulating sheet 23.

[0061] It is understandable that when the conductive foam 212 is in its original state, its height is greater than that of the insulating sheet 23, such as... Figure 2 As shown. The sample 41 is installed in the sample mounting cavity 40, and after the first insulating shell 11 and the second insulating shell 12 are fastened together, the conductive post 211 presses the conductive foam 212 tightly onto the sample 41. The conductive foam 212 is compressed, thus shrinking into the inner hole of the insulating sheet 23, as shown. Figure 5 As shown.

[0062] In this embodiment, the conductive foam 212 is surrounded by the insulating sheet 23, which improves the insulation of the fixture 100 and enhances the safety protection of the fixture 100 for test personnel.

[0063] It is understandable that the insulating sheet 23 can also increase the creepage distance between the first conductive element 21 and the second conductive element 22, thereby improving the accuracy of the insulation withstand voltage test results.

[0064] In addition, by setting the insulating sheet 23, the circumference of the conductive foam 212 can be limited, so that the conductive foam 212 is compressed in the vertical direction, improving the consistency of the compression direction of each part of the conductive foam 212, which helps to improve the reliability of the bonding between the conductive foam 212 and the sample sheet 41.

[0065] Please see Figure 4In some embodiments, the insulating sheet 23 is an insulating rubber pad; a portion of the insulating sheet 23 is located between the sample mounting cavity 40 and the first insulating shell 11. This allows the first insulating shell 11 to use the elasticity of the insulating sheet 23 to press the sample 41 firmly against the second insulating shell 12, creating a preload between the first insulating shell 11 and the sample 41. This effectively prevents the sample 41 from shaking relative to the fixture 100, improving the positional stability of the sample 41 within the sample mounting cavity 40. This, in turn, improves the accuracy of the insulation withstand voltage test results for the sample 41.

[0066] Please see Figure 4 In some embodiments, a first groove 112 is provided on the surface of the first insulating shell 11 facing the second insulating shell 12. The first groove 112 surrounds and communicates with the first wiring hole 111. The insulating sheet 23 is located within the first groove 112. This increases the mating area between the first insulating shell 11 and the insulating sheet 23, which helps to improve the positional stability of the insulating sheet 23.

[0067] For example, the insulating sheet 23 is bonded to the inner wall of the first groove 112, or the insulating sheet 23 is snapped into the first groove 112.

[0068] In some embodiments, the conductive post 211 is a copper post.

[0069] It is understandable that the copper pillar is made of copper, which has good electrical conductivity, helping to ensure stable transmission of large currents and avoiding performance degradation caused by resistance heating. This improves the accuracy of the insulation withstand voltage test results for sample 41.

[0070] Please see Figure 6 , Figure 6 This is a schematic diagram of the internal structure of the first housing provided in an embodiment of this application. In some embodiments, the first wiring hole 111 is a T-shaped hole. The first wiring hole 111 includes a horizontal hole section 1111 and a vertical hole section 1112 communicating with the middle of the horizontal hole section 1111. A conductive post 211 is disposed in the vertical hole section 1112. Conductive foam 212 is disposed in the horizontal hole section 1111. In this way, the conductive foam 212 can have a larger length dimension, thereby increasing the contact area between the conductive foam 212 and the sample 41, which is beneficial to improving the current flow capacity between the sample 41 and the conductive foam 212.

[0071] Please see Figure 2 and Figure 4 In some embodiments, a mounting groove 223 is provided on the surface of the second conductive element 22 facing the first conductive element 21. The mounting groove 223 is used to form at least a portion of the sample mounting cavity 40.

[0072] It is understandable that at least part of the sample 41 is located within the mounting slot 223.

[0073] In this embodiment, the contact area between the second conductive element 22 and the sample 41 can be increased by the above-mentioned arrangement, thereby improving the current carrying capacity between the sample 41 and the second conductive element 22.

[0074] Please see Figure 2 and Figure 3 In some embodiments, the tooling 100 further includes a first protective shell 31. The first protective shell 31 covers the outer surface of the first insulating shell 11. A first mating hole is provided on the first protective shell 31. The first mating hole communicates with the first wiring hole 111. Thus, by providing the first protective shell 31, the protective properties of the first insulating shell 11 can be improved, preventing the first insulating shell 11 from being damaged or deformed due to collisions or other reasons, thereby extending the service life of the first insulating shell 11.

[0075] In some embodiments, the first protective shell 31 is a metal component. This allows the first protective shell 31 to have higher hardness to withstand impacts and other stresses, thereby improving the protective performance of the first protective shell 31 against the first insulating shell 11.

[0076] Please see Figure 2 and Figure 3 In some embodiments, the tooling 100 further includes a second protective shell 32. The second protective shell 32 covers the outer surface of the second insulating shell 12. A second mating hole is provided on the second protective shell 32. The second mating hole communicates with the second wiring hole 121. Thus, by providing the second protective shell 32, the protective properties of the second insulating shell 12 can be improved, preventing the second insulating shell 12 from being damaged or deformed due to collisions or other reasons, thereby extending the service life of the second insulating shell 12.

[0077] In some embodiments, the second protective shell 32 is a metal component. This allows the second protective shell 32 to have higher hardness to withstand impacts and other stresses, thereby improving the protective performance of the second protective shell 32 against the second insulating shell 12.

[0078] Please see Figure 2 In some embodiments, the second conductive element 22 is a plate-like structure. One plate surface of the second conductive element 22 faces the first conductive element 21. This allows the second conductive element 22 to have a larger contact area with the sample 41, thereby improving the current-carrying capacity between the sample 41 and the second conductive element 22.

[0079] Please see Figure 2In some embodiments, the second wiring hole 121 includes a main body 1211 and an opening 1212. The main body 1211 is disposed on the end face of the second insulating shell 12 facing the first insulating shell 11. The opening 1212 is disposed on the side wall of the second insulating shell 12. The opening 1212 communicates the main body 1211 with the outside. The second conductive element 22 includes a plate portion 221 and a protruding portion 222 connected to each other. The plate portion 221 is disposed on the main body 1211. The protruding portion 222 is disposed on the opening 1212. Thus, while ensuring that the second conductive element 22 has a large contact area with the sample 41, it also has a small end for connecting to the high-voltage power supply, thereby improving the coverage of the second conductive element 22 by the second insulating shell 12, which helps to improve the safety protection of the tooling 100.

[0080] In some embodiments, the plate portion 221 and the protrusion 222 are integrally formed. This improves the reliability of the connection between the plate portion 221 and the protrusion 222, thereby enhancing the structural reliability of the second conductor.

[0081] In some embodiments, the second conductive element 22 is a copper plate.

[0082] It is understandable that the copper plate is made of copper, which has good electrical conductivity, helping to ensure stable transmission of large currents and avoiding performance degradation due to resistance heating. This improves the accuracy of the insulation withstand voltage test results for sample 41.

[0083] Please see Figure 1 and Figure 2 In some embodiments, one side of the first insulating shell 11 is hinged to one side of the second insulating shell 12. The other side of the first insulating shell 11 is connected to the other side of the second insulating shell 12 by a latch 33.

[0084] For example, the latch 33 may be an adjustable bolt-type lock clip.

[0085] In this embodiment, the above-mentioned configuration makes the opening and closing of the first insulating shell 11 and the second insulating shell 12 simple and convenient, thereby improving the operability of the tooling 100 and improving the efficiency of the insulation withstand high voltage test of the insulating layer.

[0086] Specifically, when the tooling 100 also includes a first protective shell 31 and a second protective shell 32, the first insulating shell 11 is fixedly connected to the first protective shell 31, and the second insulating shell 12 is fixedly connected to the second protective shell 32. One side of the first protective shell 31 is hinged to one side of the second protective shell 32, thereby achieving hinged connection between one side of the first insulating shell 11 and one side of the second insulating shell 12. The other side of the first protective shell 31 is connected to the other side of the second protective shell 32 via a latch 33, thereby achieving connection between the other side of the first insulating shell 11 and the other side of the second insulating shell 12 via a latch 33.

[0087] Secondly, embodiments of this application provide a testing device, which includes the aforementioned tooling 100.

[0088] It is understood that the testing equipment may also include a voltmeter for monitoring the voltage applied to the sample 41, an ammeter for monitoring the current magnitude, a timer for monitoring the time the sample 41 withstands high voltage, etc.

[0089] It is understood that the testing equipment includes the aforementioned tooling 100, and the testing equipment has all the beneficial effects of the aforementioned tooling 100, which will not be described in detail in this embodiment.

[0090] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
