[0027] Currently, the insulation withstand voltage of injection-molded copper busbars is the core guarantee for the safe operation of high-voltage electrical systems in new energy vehicles. However, the existing insulation withstand voltage test method usually involves manually clamping the injection-molded copper busbars at both ends of the tester. The test conditions are unstable, which can easily lead to missed tests and reduce the stability of the test results.
[0028] To address the issues of missed tests and low stability of test results, this application provides an insulation withstand voltage testing fixture and an insulation withstand voltage testing system. The fixture includes: an insulating base with a first recess and a second recess. The first recess is located on one side of the insulating base, and the second recess is located in the center of the insulating base. The first recess is used to place the first connecting terminal of the injection-molded copper busbar, and the second recess is used to place the plastic body of the injection-molded copper busbar; a first copper post is disposed in the first recess and is used to connect to the first connecting terminal of the injection-molded copper busbar; a second copper post is disposed on the other side of the insulating base and is used to connect to the second connecting terminal of the injection-molded copper busbar; an interface circuit is disposed inside the insulating base, and the first copper post is connected to the voltage terminal of the tester through the interface circuit, and the second copper post is connected to the ground terminal of the tester through the interface circuit; and a fixing buckle is disposed on one side of the insulating base and is used to fix the injection-molded copper busbar. According to the solution provided in the embodiments of this application, the insulating base is provided with a first recess and a second recess. The first recess is located on one side of the insulating base, and the second recess is located in the center of the insulating base. A first copper post is disposed in the first recess, and a second copper post is disposed on the other side of the insulating base. Therefore, the first recess of the injection-molded copper busbar can accommodate the first connecting terminal of the injection-molded copper busbar, the second recess can accommodate the plastic body of the injection-molded copper busbar, the first copper post can connect to the first connecting terminal of the injection-molded copper busbar, and the second copper post can connect to the second connecting terminal of the injection-molded copper busbar. This provides a standardized testing environment for the injection-molded copper busbar, thereby preventing missed tests. To improve the stability of test results, the interface circuit is located inside the insulating base. The first copper pillar is connected to the voltage terminal of the tester through the interface circuit, and the second copper pillar is connected to the ground terminal of the tester through the interface circuit, thus constructing a complete test environment. A fixing buckle is located on one side of the insulating base. The fixing buckle is used to fix the injection-molded copper busbar, which can prevent the injection-molded copper busbar from shifting during the test and prevent poor contact between the two ends of the injection-molded copper busbar and the copper pillar, thereby preventing missed tests and further improving the stability of the insulation withstand voltage test results. In addition, the interface circuit can also assist the insulation withstand voltage test, thereby improving the accuracy, efficiency and safety of the test.
[0029] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0030] Reference Figures 1 to 4 This application provides an insulation withstand voltage test fixture 100, comprising:
[0031] An insulating base 110 is provided with a first recess 111 and a second recess 112. The first recess 111 is located on one side of the insulating base 110, and the second recess 112 is located in the center of the insulating base 110. The first recess 111 is used to place the first connecting terminal 210 of the injection-molded copper busbar 200, and the second recess 112 is used to place the plastic body 220 of the injection-molded copper busbar 200.
[0032] The first copper pillar 120 is disposed in the first recess 111, and the first copper pillar 120 is used to connect the first connecting terminal 210 of the injection-molded copper busbar 200.
[0033] The second copper post 130 is disposed on the other side of the insulating base 110. The second copper post 130 is used to connect the second connection terminal 230 of the injection-molded copper busbar 200.
[0034] An interface circuit (not shown in the figure) is set inside the insulating base 110. The first copper pillar 120 is connected to the voltage terminal of the tester (not shown in the figure) through the interface circuit, and the second copper pillar 130 is connected to the ground terminal of the tester through the interface circuit.
[0035] The fixing buckle 140 is located on one side of the insulating base 110 and is used to fix the injection-molded copper busbar 200.
[0036] The insulating base 110 can be rectangular in shape, and its length-to-width ratio can be 2:1. This embodiment of the present disclosure does not limit the shape.
[0037] The first connecting terminal 210 is provided with a first through hole 211 for the first copper post 120 to pass through; the second connecting terminal 230 is provided with a second through hole 231 for the second copper post 130 to pass through.
[0038] It should be noted that when the first copper post 120 passes through the first through hole 211, the first copper post 120 contacts the first connecting terminal 210; when the second copper post 130 passes through the second through hole 231, the second copper post 130 contacts the second connecting terminal 230.
[0039] The injection-molded copper busbar 200 can be formed by injection molding from multiple independent copper busbars. For example, the injection-molded copper busbar 200 can include two copper busbars, which are separated by injection molding. When the injection gap between the two copper busbars is insufficient or there is contact, the tester will display that the pressure resistance value is insufficient, indicating that the test of this injection-molded copper busbar 200 is unqualified; otherwise, it indicates that it is qualified.
[0040] It should be noted that the specific testing steps are as follows: Power on the tester and adjust it to the specified parameters to ensure that the tester is working properly. Then, place the injection-molded copper busbar 200 on the insulation withstand voltage test fixture 100 and fix the injection-molded copper busbar 200 in place with the fixing buckle 140. Then, ensure that the first copper post 120 and the second copper post 130 on the insulation withstand voltage test fixture 100 are in good contact with the injection-molded copper busbar 200. Then, start the test. After the tester continuously applies voltage to the injection-molded copper busbar 200 for the specified time, wait for the tester to display whether it is qualified or unqualified.
[0041] Understandably, testing the insulation requirements of 200 injection-molded copper busbars reduces the risk of short circuits. At the same time, the insulation testing fixture allows for rapid testing without the need for manual inspection of individual products, thus improving testing efficiency.
[0042] It should be noted that the insulation withstand voltage test fixture 100 can be changed according to the shape of the injection-molded copper busbar 200, and different injection-molded copper busbars 200 can be tested quickly.
[0043] It should be noted that the interface circuit can be a protection circuit, which can automatically cut off the power when the current is too high, or prevent the generation of electric arc when the injection-molded copper busbar 200 is unqualified. For example, the tester may be unable to prevent the internal circuit of the insulation test fixture or the two ends of the tester from burning out due to response delay, while the local protection of the insulation test fixture can intercept the fault in advance.
[0044] Based on this, the insulating base 110 is provided with a first recess 111 and a second recess 112. The first recess 111 is located on one side of the insulating base 110, and the second recess 112 is located in the center of the insulating base 110. Then, a first copper post 120 is disposed in the first recess 111, and a second copper post 130 is disposed on the other side of the insulating base 110. Therefore, the first recess 111 of the injection-molded copper busbar 200 can accommodate the first connecting terminal 210 of the injection-molded copper busbar 200, the second recess 112 can accommodate the plastic body 220 of the injection-molded copper busbar 200, the first copper post 120 can connect to the first connecting terminal 210 of the injection-molded copper busbar 200, and the second copper post 130 can connect to the second connecting terminal 230 of the injection-molded copper busbar 200. The system provides a standardized testing environment to prevent missed tests and improve the stability of test results. The interface circuit is located inside the insulating base 110. The first copper pillar 120 is connected to the voltage terminal of the tester through the interface circuit, and the second copper pillar 130 is connected to the ground terminal of the tester through the interface circuit, thus constructing a complete testing environment. The fixing buckle 140 is located on one side of the insulating base 110. The fixing buckle 140 is used to fix the injection-molded copper busbar 200, which can prevent the injection-molded copper busbar 200 from shifting during the test and prevent poor contact between the two ends of the injection-molded copper busbar 200 and the copper pillar, thereby preventing missed tests and further improving the stability of the insulation withstand voltage test results. In addition, the interface circuit can also assist the insulation withstand voltage test, thereby improving the accuracy, efficiency and safety of the test.
[0045] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the insulating base 110 is further provided with a third recess 113, which is located on the side of the second recess 112 near the second copper pillar 130.
[0046] Based on this, the insulating base 110 is also provided with a third recess 113, which is located on the side of the second recess 112 near the second copper column 130. This allows the insulation test fixture to better match the structure of the injection-molded copper busbar 200, thereby improving the accuracy and stability of the test results.
[0047] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, a first copper pillar 120 is vertically inserted into an insulating base 110, and a second copper pillar 130 is vertically inserted into an insulating base 110. The bottom end of the first copper pillar 120 is connected to the voltage terminal of the tester, and the bottom end of the second copper pillar 130 is connected to the ground terminal of the tester.
[0048] Based on this, since the first copper pillar 120 and the second copper pillar 130 are both vertically inserted into the insulating base 110, the bottom ends of both the first copper pillar 120 and the second copper pillar 130 are located on the bottom surface of the insulating base 110. The bottom end of the first copper pillar 120 is connected to the voltage terminal of the tester, and the bottom end of the second copper pillar 130 is connected to the grounding terminal of the tester. Since the bottom surface of the insulating base 110 is usually not exposed to the tester during testing, it can prevent accidental contact by the tester, thereby improving the safety of the test and the accuracy and stability of the test structure.
[0049] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the height of the top of the first copper pillar 120 is greater than the height of the insulating base 110, and the height of the top of the second copper pillar 130 is greater than the height of the insulating base 110. The top of the first copper pillar 120 is used to connect to the first connecting terminal 210 of the injection-molded copper busbar 200, and the top of the second copper pillar 130 is used to connect to the second connecting terminal 230 of the injection-molded copper busbar 200.
[0050] Based on this, since the height of the top of the first copper column 120 is greater than the height of the insulating base 110, and the height of the top of the second copper column 130 is greater than the height of the insulating base 110, the top of the first copper column 120 can be connected to the first connecting terminal 210 of the injection-molded copper busbar 200, and the top of the second copper column 130 can be connected to the second connecting terminal 230 of the injection-molded copper busbar 200. This naturally matches the direction of the tester's vertical placement of the injection-molded copper busbar 200 and the pressure applied by the fixing buckle 140, thus optimizing human-machine interaction and operational efficiency.
[0051] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the cross-sectional shape of the first recess 111 and the third recess 113 is rectangular, and the width of the first recess 111 is smaller than the width of the third recess 113.
[0052] It should be noted that the shape of the first connecting terminal 210 of the injection-molded copper busbar 200 matches the shape of the first recess 111;
[0053] The third recess 113 is also used to place the plastic body 220 of the injection-molded copper busbar 200.
[0054] Based on this, the cross-sectional shape of the first recess 111 and the third recess 113 is rectangular. The width of the first recess 111 is smaller than the width of the third recess 113, which can better match the structure of the injection-molded copper busbar 200, thereby improving the accuracy and stability of the test results.
[0055] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the second recess 112 includes a first sub-recess 114, a second sub-recess 115, and a third sub-recess 116 arranged sequentially. The cross-sectional shape of the first sub-recess 114, the second sub-recess 115, and the third sub-recess 116 is rectangular. The width of the first sub-recess 114 is smaller than the width of the second sub-recess 115, and the width of the second sub-recess 115 is smaller than the width of the third sub-recess 116.
[0056] Based on this, the cross-sectional shape of the first sub-recess 114, the second sub-recess 115, and the third sub-recess 116 is rectangular. The width of the first sub-recess 114 is smaller than the width of the second sub-recess 115, and the width of the second sub-recess 115 is smaller than the width of the third sub-recess 116. This better matches the structure of the injection-molded copper busbar 200, thereby improving the accuracy and stability of the test results.
[0057] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the depth of the first recess 111 is less than the depth of the third recess 113, and the depth of the third recess 113 is less than the depth of the second recess 112.
[0058] Based on this, the depth of the first recess 111 is less than the depth of the third recess 113, and the depth of the third recess 113 is less than the depth of the second recess 112, which can better match the structure of the injection-molded copper busbar 200, thereby improving the accuracy and stability of the test results.
[0059] Additionally, refer to again Figures 1 to 4In some embodiments of this application, the fixing buckle 140 includes a base 141, a positioning terminal 144, a first lever arm 142, and a second lever arm 143. The first lever arm 142 is disposed on the side of the base 141 near the insulating base 110, and the second lever arm 143 is disposed on the other side of the base 141 away from the insulating base 110. One end of the first lever arm 142 is rotatably connected to the base 141, and the other end of the first lever arm 142 is connected to the positioning terminal 144. One end of the second lever arm 143 is rotatably connected to the base 141, and the end of the first lever arm 142 near the base 141 is gear-connected to the end of the second lever arm 143 near the base 141.
[0060] It should be noted that when the end of the second lever arm 143 away from the base 141 is pressed, the gear of the second lever arm 143 drives the gear of the first lever arm 142 to rotate, so that the positioning terminal 144 on the first lever arm 142 approaches and presses against the injection-molded copper busbar 200. The contact surface between the positioning terminal 144 and the injection-molded copper busbar 200 is relatively rough, which can effectively prevent the injection-molded copper busbar 200 from sliding, improve the stability of the test, and can also simulate the actual working scenario of the injection-molded copper busbar 200 in combination with the first copper column 120 and the second copper column 130, thereby improving the reliability of the test.
[0061] Based on this, the first lever arm 142 is located on the side of the base 141 near the insulating base 110, and the second lever arm 143 is located on the other side of the base 141 away from the insulating base 110. One end of the first lever arm 142 is rotatably connected to the base 141, and the other end of the first lever arm 142 is provided with a positioning terminal 144. One end of the second lever arm 143 is rotatably connected to the base 141, and the end of the first lever arm 142 near the base 141 and the end of the second lever arm 143 near the base 141 are geared together, which can improve the reliability and stability of the test.
[0062] Additionally, refer to again Figures 1 to 4 In some embodiments of this application, the insulating base 110 is made of wood.
[0063] Based on this, the insulating base 110 is made of wood. Since the damping properties of wood can absorb mechanical vibration, it can reduce the impact of noise on the test results during the test, thereby improving the accuracy and stability of the test results.
[0064] In one possible implementation, the insulating base 110 may also be made of one or more of the following materials: polyamide, polycarbonate, polyetheretherketone, aluminum alloy, stainless steel, glass fiber reinforced plastic, or ceramic matrix composite.
[0065] Additionally, refer to Figure 5 , Figure 5 A top view of the insulation withstand voltage test system provided in the embodiments of this application, and again referring to... Figures 1 to 4According to certain embodiments of this application, an insulation withstand voltage test system 300 includes:
[0066] Support plate 310;
[0067] Multiple insulation withstand voltage test fixtures 100 are arranged side by side on the support plate 310. The first copper column 120 of the insulation withstand voltage test fixture 100 is used to connect to the first connecting terminal 210 of the injection molded copper busbar 200, and the second copper column 130 of the insulation withstand voltage test fixture 100 is used to connect to the second connecting terminal 230 of the injection molded copper busbar 200.
[0068] The tester is equipped with a voltage terminal and a ground terminal. The voltage terminal is connected to the first copper post 120, and the ground terminal is connected to the second copper post 130.
[0069] It should be noted that the tester can be set with multiple detection modules. Each detection module includes a voltage terminal and a ground terminal. Each voltage terminal is connected to the corresponding first copper post 120, and each ground terminal is connected to the corresponding second copper post 130, thereby realizing parallel testing and improving testing efficiency.
[0070] Based on this, multiple insulation withstand voltage test fixtures 100 are arranged side by side on the support plate 310. The tester is equipped with a voltage terminal and a grounding terminal. The voltage terminal is connected to the first copper column 120, and the grounding terminal is connected to the second copper column 130. The first copper column 120 of the insulation withstand voltage test fixture 100 is used to connect to the first connection terminal 210 of the injection-molded copper busbar 200, and the second copper column 130 of the insulation withstand voltage test fixture 100 is used to connect to the second connection terminal 230 of the injection-molded copper busbar 200. This allows for simultaneous testing of the injection-molded copper busbars 200 on multiple insulation withstand voltage test fixtures 100, thereby improving testing efficiency.
[0071] It is understood that the specific implementation of the insulation withstand voltage test system 300 is basically the same as the specific embodiment of the insulation withstand voltage test fixture 100 described above, and will not be repeated here.
[0072] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
