[0038] like Figure 1 As shown, the test piece in this embodiment includes a body 1, a test part 2, a metal part 3, and a wire 4. The test part 2 and the wire 4 are located at the two ends of the body 1, and the metal part 3 is located at the end of the test part 2 away from the body 1. The test part 2 and the metal part 3 are integrally formed. The test part 2 is coated with an anti-corrosion coating. When performing insulation withstand voltage testing, a shielding part 40 needs to be fitted onto the metal part 3.
[0039] To perform an insulation withstand voltage test on the aforementioned test components, such as Figures 2 to 4 As shown, this embodiment provides a detection device, which includes a first detection component 10 and a second detection component 20. The first detection component 10 includes a base 11 and a first adsorption member 12. The base 11 is provided with a placement groove 111 and a first conductive groove 112 that are interconnected. The first adsorption member 12 protrudes from the first conductive groove 112 and adsorbs a conductive medium. The second detection component 20 includes a cover 21 and a second adsorption member 22. The cover 21 and the base 11 are movably connected. The cover 21 is provided with a second conductive groove 211. The second conductive groove 211 can be arranged opposite to the first conductive groove 112 to form a test space. The second adsorption member 22 protrudes from the second conductive groove 211 and adsorbs a conductive medium.
[0040] Specifically, in the embodiment, the base 11 and the cover 21 are movably connected, which can facilitate the connection or separation of the base 11 and the cover 21, and improve the convenience in use; the placing groove 111 of the base 11 is in communication with the first conductive groove 112, which can enable the measured part 2 of the measured member placed in the placing groove 111 to extend into the first conductive groove 112 for testing; the first suction member 12 is protruded from the first conductive groove 112, and the second suction member 22 is protruded from the second conductive groove 211; the first suction member 12 and the second suction member 22 are provided with detection wire harnesses, and the first suction member 12 and the second suction member 22 are both adsorbed with conductive medium; when testing, the base 11 and the cover 21 are separated first, and then the measured member is placed in the placing groove 111; then the base 11 and the cover 21 are buckled, so that the first suction member 12 and the second suction member 22 are pressed against each other to release the conductive medium; at this time, the detection part of the measured member is located between the first suction member 12 and the second suction member 22, and the conductive medium can completely wrap the measured part 2; then the wires 4 of the measured member and the detection wire harnesses are electrified to perform insulation withstand voltage test on the measured member. The detection device can not only completely wrap the measured part 2 of the measured member with the conductive medium to ensure the detection effect, but also avoid damaging the coating of the measured part 2 by using other clamps; and after the test is completed, the base 11 and the cover 21 are separated, and the first suction member 12 and the second suction member 22 can re-adsorb the released conductive medium to avoid waste of the conductive medium.
[0041] Specifically, in the embodiment, the first suction member 12 and the second suction member 22 are both sponges, and the length of at least one of the sponges is greater than the length of the first conductive groove 112 and the second conductive groove 211, which can ensure that the first suction member 12 and the second suction member 22 are respectively limited in the first conductive groove 112 and the second conductive groove 211, and avoid the second suction member 22 from being detached from the second conductive groove 211 during the separation of the cover 21 and the base 11. The conductive medium in the embodiment is saline water, and the concentration of the saline water is set according to actual use, which will not be described here.
[0042] Specifically, in the embodiment, please refer to Figure 5 The cover 21 and the base 11 are both provided with wire harness channels 17 for accommodating the detection wire harnesses.
[0043] Specifically, in the embodiment, please refer to Figure 5 The base 11 is also provided with a wire channel 18, which is in communication with the outside and the placing groove 111, and the wires 4 of the measured member extend out of the base 11 through the wire channel 18.
[0044] Specifically, in the embodiment, please refer to Figure 6The bottom surface of the placement groove 111 is higher than the bottom surface of the first conductive groove 112. This arrangement can prevent the conductive medium in the first conductive groove 112 from wetting the test piece body 1. Since the conductive medium is salt water, which has a certain degree of corrosiveness, it can prevent corrosion of the test piece body 1.
[0045] Further, please refer to Figure 4 The detection device also includes a first locking member and a second locking member. The first locking member is disposed on the base 11, and the second locking member is disposed on the cover 21. The first locking member and the second locking member are detachably connected. Specifically, in this embodiment, the first locking member is disposed on the base 11, and the second locking member is disposed on the cover 21. The first locking member and the second locking member are detachably connected, which can ensure that the base 11 and the cover 21 can be tightly attached to each other, so as to exert a strong squeezing effect on the first adsorption member 12 and the second adsorption member 22, thereby ensuring that the conductive medium can be released normally and ensuring the accuracy of the detection results of the tested item. At the same time, it can also ensure that the relative position of the cover 21 and the base 11 will not move during the test, thereby avoiding affecting the detection effect of the tested item.
[0046] Further, please refer to Figure 4 The first locking element is a first magnet 13, and the second locking element is a second magnet 23. The first magnet 13 and the second magnet 23 are magnetically attracted together. Specifically, in this embodiment, the first magnet 13 and the second magnet 23 are attracted together when the cover 21 and the base 11 are fastened together, which can fix the relative positions of the cover 21 and the base 11 and ensure that the two opposing surfaces of the cover 21 and the base 11 are in close contact. This ensures that the first adsorption element 12 and the second adsorption element 22 can be squeezed against each other, ensuring the normal release of the conductive medium, and thus ensuring the normal progress of the experiment.
[0047] In another embodiment, a pressure plate can be provided on the base 11. After the cover plate is fastened to the base 11, the pressure plate can press firmly on the top of the cover plate. This can ensure the stability of the relative position of the cover plate and the base 11, and also ensure the mutual compression of the first adsorption member 12 and the second adsorption member 22, ensuring the normal release of the conductive medium and the normal progress of the experiment.
[0048] Further, please refer to Figure 5 and Figure 6The base 11 is provided with an overflow groove 14, which is spaced apart from the first conductive groove 112 and connected through a medium channel 15. Specifically, in this embodiment, the base 11 is provided with an overflow groove 14 that is spaced apart from and connected to the first conductive groove 112. During the actual test, the first adsorption member 12 and the second adsorption member 22 are squeezed against each other, and the conductive medium is released. When there is too much conductive medium, the excess conductive medium can enter the overflow groove 14 through the medium channel 15, preventing the conductive medium from overflowing from the gap between the cover 21 and the base 11, thereby avoiding short circuits. When the conductive medium in the first adsorption member 12 and the second adsorption member 22 is insufficient, the conductive medium in the overflow groove 14 can enter the first conductive groove 112 through the medium channel 15 to replenish the conductive medium, thereby ensuring that the conductive medium can fully cover the tested part 2 of the test piece, thereby improving the accuracy of the experimental results.
[0049] Specifically, in this embodiment, please refer to Figure 5 and Figure 6 There are two medium channels 15, which are spaced apart. This arrangement can improve the efficiency of the conductive medium flow and effectively prevent the conductive medium from flowing out along the gap between the cover 21 and the base 11. At the same time, it can prevent the conductive medium in the first conductive groove 112 from being insufficient and replenish the conductive medium in the first conductive groove 112 in time to ensure the efficiency of the test.
[0050] Optionally, in this embodiment, please refer to Figure 4 Another overflow groove 14 corresponding to the overflow groove 14 is also provided on the cover 21. The other overflow groove 14 is connected to the second conductive groove 211 of the cover 21. This arrangement enables the normal export and replenishment of the conductive medium in the second conductive groove 211 even when the detection device needs to be inverted, thereby improving the flexibility of use.
[0051] Further, please refer to Figure 5 and Figure 6 An avoidance groove 16 is provided between the overflow groove 14 and the first conductive groove 112, and the avoidance groove 16 is spaced apart from the medium channel 15. Specifically, in this embodiment, considering that the tested part 2 of some test pieces is located in the middle section of the test piece, an avoidance groove 16 is provided between the overflow groove 14 and the first conductive groove 112 to accommodate the part of the test piece that is not being tested. This can avoid bumping and wear on the untested part, and also ensure that the cover 21 and the base 11 are properly and tightly attached, ensuring the normal conduction of the test of the tested part 2.
[0052] Further, please refer to Figure 3The cover 21 and the base 11 are rotatably connected by a hinge 30. Specifically, in this embodiment, the cover 21 and the base 11 are rotatably connected by a hinge 30. In actual use, the base 11 is placed on a flat surface, and the cover 21 and the base 11 are rotatably connected by a hinge 30, which makes it easy to separate or attach the cover 21 and the base 11, improving the convenience of use, and ensuring the integrity of the cover 21 and the base 11, preventing the cover 21 from being lost.
[0053] Optionally, in another embodiment, a guide rail is vertically arranged on the base 11, and the cover 21 is slidably arranged on the guide rail. When it is necessary to separate the cover 21 from the base 11, the cover 21 moves away from the base 11 along the guide rail. When it is necessary to fit the cover 21 and the base 11 together, the cover 21 moves closer to the base 11 along the guide rail until it fits the base 11, which also allows the detection to proceed normally.
[0054] Further, please refer to Figure 4 and Figure 7 A toggle block 212 is provided on the cover 21, and the toggle block 212 is located on the side of the cover 21 away from the hinge 30. Specifically, in this embodiment, when it is necessary to separate the cover 21 and the base 11, the operator can rotate the cover 21 by using the toggle block 212, thereby improving the convenience of use.
[0055] Further, please refer to Figure 5 The base 11 is also provided with guide members 113. Two guide members 113 are spaced apart on the surface of the base 11 to form a receiving space, and the cover 21 is located in the receiving space. Specifically, in this embodiment, the two guide members 113 form a receiving space on the surface of the base 11, which can guide the cover 21, thereby ensuring that the first conductive groove 112 and the second conductive groove 211 can be aligned, thereby ensuring the relative position of the first adsorption member 12 and the second adsorption member 22, thus ensuring the normal release of the conductive medium and ensuring the accuracy of the test results.
[0056] Further, please refer to Figure 6 The base 11 is also provided with an abutment block 114, which protrudes from the bottom surface of the placement groove 111 and abuts against the first adsorption member 12. Specifically, in this embodiment, the abutment block 114 can both abut against the first adsorption member 12 to ensure the accurate positioning of the first adsorption member 12 and abut against the test piece to improve the positional stability of the test piece. In this embodiment, the test piece includes two test parts 2, which are located on both sides of the abutment block 114, thereby improving the positional stability of the test piece and ensuring the normal conduct of the test.
[0057] In another embodiment, the number of abutment blocks 114 can be specifically set according to actual use, which will not be elaborated here.
[0058] Further, please refer to Figure 1 The testing device also includes a shielding component 40, which shields the metal portion 3 of the test piece. Since some test pieces have their test portion 2 directly connected to the metal portion 3, and the metal portion 3 needs to be shielded during the insulation withstand voltage test, the shielding component 40 ensures the insulation of the metal portion 3 during the test, preventing any disruption to the normal conduct of the test. Specifically, in this embodiment, the shielding component 40 is a rubber sleeve, which is fitted over the metal portion 3 of the test portion 2 of the test piece, effectively providing insulation and ensuring the normal conduct of the test.
[0059] The detection process of the detection device in this embodiment is described in detail below. First, the cover 21 is rotated relative to the base 11 by the actuating component, causing the cover 21 and the base 11 to separate. Then, the first adsorbent 12 and the second adsorbent 22 adsorb the saline solution, and the first adsorbent 12 is placed in the first conductive groove 112, the second adsorbent 22 is placed in the second conductive groove 211, and the detection harness is connected to the first adsorbent 12 and the second adsorbent 22. The other end of the detection harness extends out of the base 11 through the harness channel 17. The shielding component 40 is sleeved on the metal part 3 of the part being tested 2. The test piece is placed in the placement slot 111, so that the abutment block 114 and the test piece abut against each other, and the two test parts 2 are located on both sides of the abutment block 114. The cover 21 is rotated relative to the base 11 by the actuating component, and the cover 21 and the base 11 are in contact. Under the action of the first magnet 13 and the second magnet 23, the first adsorption component 12 and the second adsorption component 22 are squeezed against each other, and the salt water is released to coat the coating of the test part 2. Then, the wire 4 and the detection wire harness of the test piece are energized to carry out the insulation withstand voltage test of the test piece.
