[0002] Currently, the development of new energy vehicles is becoming more and more widespread. Considering the lightweight development of vehicle bodies is becoming a key issue in the industry. The use of injection-molded copper busbars is inevitable. While using injection-molded copper busbars can help reduce vehicle weight, the safe distance between copper busbars has also become a key concern in the current industry. Therefore, it is necessary to conduct electrical withstand voltage testing on the electrical safety distance of injection-molded copper busbars. Generally, the condition cycle of electrical withstand voltage testing is long and the time is not fixed.

[0024] See also Figure 1 The utility model provides a multi-station injection molded copper busbar withstand voltage detection device, including multiple test stations 10, multiple test stations 10 are connected in parallel through parallel end electronic wires 22, the parallel end electronic wires 22 are connected to the input end probes 20 of the test stations 10, and the input end probe 20 of one test station 10 is connected to the withstand voltage tester through the input end electronic wire 21.

[0025] Specifically, in an embodiment of the present invention, the electrical withstand voltage testing device for an injection-molded copper busbar 100 includes two test stations 10. The two ends of a parallel-end electronic wire 22 are connected to the input-end probes 20 of the two test stations 10, respectively. One end of an input-end electronic wire 21 is connected to one of the test stations 10, and the other end of the input-end electronic wire 21 is connected to a withstand voltage tester. Thus, the electrical withstand voltage test of the injection-molded copper busbar 100 can be performed by installing the two injection-molded copper busbars 100 to be tested on the two test stations 10, respectively, and then connecting the parallel-end electronic wire 22 and the input-end electronic wire 21 to the withstand voltage tester.

[0026] More specifically, the test station 10 is provided with input probes 20 corresponding to the number of terminals of the injection-molded copper busbar 100. For example, for a common three-wire circuit, three input probes 20 are provided on the test station 10 corresponding to the three terminals on the injection-molded copper busbar 100. Three input electronic wires 21 and three parallel electronic wires 22 are also provided. In other words, the required test station 10, the number of input probes 20, the number of input electronic wires 21, and the number of parallel electronic wires 22 are selected based on the number of terminals of the injection-molded copper busbar 100, the number of terminals involved in the withstand voltage test, and the number of injection-molded copper busbars 100 to be tested. Detailed description is omitted here.

[0027] It should be noted that by using parallel-end electronic wires 22 to connect multiple test stations 10 in parallel, the withstand voltage testing device can be connected to multiple stations, allowing simultaneous testing of multiple products such as injection-molded copper busbars 100. Furthermore, the multiple test stations 10 connected in parallel can perform withstand voltage testing simultaneously or individually, thereby identifying the location of defective products in the test results, thereby improving the testing efficiency and test application diversity of the withstand voltage testing device.

[0028] In one embodiment, a plurality of test stations 10 are installed on a base. For products such as the injection molded copper busbar 100, it is widely used in lightweight structures of new energy vehicle bodies and other electrical structures. Therefore, the output of the injection molded copper busbar 100 is large, and there is a need to quickly perform a withstand voltage test. For example, a plurality of test stations 10 can be arranged and installed on the same base (not shown in the accompanying drawings), and other forms can also be used to install them on other structural parts, and then other manipulators and other devices can be used to load and unload the injection molded copper busbar 100 to achieve automated withstand voltage testing, thereby further improving the withstand voltage testing efficiency of products such as the injection molded copper busbar 100.

[0029] See also Figure 1 and Figure 2 In one embodiment, the test station 10 is further provided with a pair of connection end probes 30 , and the connection end probes 30 are connected by connection end electronic wires 31 .

[0030] Specifically, in the embodiment of the present invention, for injection-molded copper busbars 100 of different types or complex structures, which have different forms of terminal structures, the connection end probes 30 designed on the test station 10 allow the disconnected ends of the copper busbars 100 to be connected together by two pairs of connection end probes 30 when testing non-integrated injection-molded copper busbars 100, and a single withstand voltage measurement is performed to meet the test of the entire injection-molded copper busbar 100 structure, avoiding multiple measurements of disconnected paths in the injection-molded copper busbar 100 structure, thereby improving the withstand voltage test efficiency of the tooling, i.e., the test station 10, on the injection-molded copper busbar 100.

[0031] More specifically, the connection end probes 30 are arranged at corresponding positions of the test station 10 according to the structure of the injection-molded copper busbar 100 to be tested, and the pairs of connection end probes 30 are connected via the connection end electronic wires 31, thereby reconnecting the broken paths in the structure of the injection-molded copper busbar 100. Similarly, for a structure with multiple broken paths in the structure of the injection-molded copper busbar 100, the connection end probes 30 corresponding to the number of paths can also be arranged at corresponding positions of the test station 10 to connect multiple paths of different types, thereby facilitating direct voltage withstand testing.

[0032] See also Figures 1 to 3 In one embodiment, a telescopic cylinder 40 is further mounted on the test station 10, and an input probe 20 is mounted on the telescopic cylinder 40. The telescopic cylinder 40 is mounted upside down on the test station 10. The telescopic cylinders 40 on multiple test stations 10 are controlled by a single air valve switch.

[0033] Specifically, in an embodiment of the present invention, after the injection-molded copper busbar 100 to be tested is installed on the test station 10, the input-end probe 20 is driven by the telescopic cylinder 40 to abut against the corresponding terminal of the injection-molded copper busbar 100. Compared with installing the injection-molded copper busbar 100 on the test station 10 to form a overlap with the input-end probe 20, it is more stable and avoids errors caused by poor contact between the input-end probe 20 and the injection-molded copper busbar 100 during the withstand voltage test.

[0034] More specifically, by inverting the telescopic cylinder 40 installed on the test station 10, the input end probe 20 can be connected through the support base 41 installed on the telescopic rod of the telescopic cylinder 40, thereby shortening the stroke of the telescopic cylinder 40, so that a larger cylinder model can be selected when selecting the cylinder. At the same time, the overall volume can be reduced when installed on the test station 10, making the pressure resistance detection device lighter.

[0035] It should be noted that the telescopic cylinders 40 on multiple test stations 10 are controlled by a single air valve switch. When one or more products such as the injection molded copper busbar 100 to be tested are installed on multiple test stations 10, the single air valve switch is operated to control all the telescopic cylinders 40 to move and clamp on the terminal blocks of the injection molded copper busbar 100, thereby connecting the input probe 20 to the injection molded copper busbar 100 on the test station 10 and performing a withstand voltage test. In the test station 10 where the injection molded copper busbar 100 to be tested is not installed, the movement of the input probe 20 driven by the telescopic cylinder 40 will not be affected, and a connection with the input electronic wire 21 and the withstand voltage tester is formed between the multiple test stations 10 through the parallel end electronic wire 22 to perform a withstand voltage test. This allows for convenient control of the telescopic cylinders 40 in multiple test stations 10 by a single air valve switch.

[0036] In one embodiment, springs connect the telescopic cylinder 40 and the input probe 20, as well as the connection probe 30 and the test station 10. The input probe 20 and the connection probe 30 abut the connection terminals of the injection-molded copper busbar 100. The parallel-end electronic wire 22 and the connection-end electronic wire 31 are movably connected to the input probe 20 and the connection probe 30.

[0037] Specifically, in an embodiment of the present invention, the input terminal probe 20 and the connection terminal probe 30 for contacting the connection terminals of the injection molded copper bar 100 are both connected to the test station 10 by a spring (not shown in the accompanying drawings), wherein at the position of the input terminal probe 20, the spring is installed on the support base 41 of the telescopic cylinder 40. In this way, when installing products such as the injection molded copper bar 100 to be tested, the input terminal probe 20 and the connection terminal probe 30 can be provided with prestressed contact on the connection terminals corresponding to the injection molded copper bar 100 to be tested, maintaining the stability of the electrical connection therebetween. The input terminal probe 20 can also cooperate with the drive of the telescopic cylinder 40 to further control the prestressed force applied to the connection terminals on the injection molded copper bar 100 to be tested, thereby ensuring the contact state between the input terminal probe 20 and the connection terminals of the injection molded copper bar 100 to be tested, and maintaining the stability of the electrical connection during the withstand voltage test.

[0038] More specifically, in the lightweight structure and electrical structure of the vehicle body using the injection-molded copper busbar 100, there are also injection-molded copper busbars 100 of various different models and structures. Therefore, the positions of the input end probe 20 and the connection end probe 30 need to be adjusted accordingly in the test station 10. Similarly, in the process of adjusting the positions of the input end probe 20 and the connection end probe 30, the electronic wires connected therebetween also need to be rewired. Therefore, the parallel end electronic wire 22, the input end electronic wire 21 and the connection end electronic wire 31 can be installed and connected to the input end probe 20 and the connection end probe 30 through nuts, and can be synchronously loaded and unloaded as the positions of the input end probe 20 and the connection end probe 30 are adjusted, thereby improving the flexibility of the voltage withstand test device.

[0039] See also Figure 1 and Figure 3 In one embodiment, the test station 10 is further provided with a contoured groove 50 that matches the outer contour of the injection-molded copper busbar 100. Specifically, to further improve the assembly efficiency and accuracy of the injection-molded copper busbar 100 and other products to be tested on the test station 10, a contoured groove 50 structure corresponding to the outer contour of the injection-molded copper busbar 100 and other products to be tested can be provided on the test station 10. This allows for more convenient positioning and subsequent securing of the injection-molded copper busbar 100 and other products to be tested on the test station 10. Furthermore, when the product is placed on the tooling for measurement, it is more securely positioned to prevent movement, resulting in more accurate measurement results.

[0040] In summary, the utility model provides a multi-station injection molded copper busbar withstand voltage test device. By providing multiple test stations and the telescopic cylinders respectively installed thereon, the respective input end probes and the parallel end electronic wires connected therebetween, the respective connection end probes and the connection end electronic wires connected therebetween, and the air valve switches connected to the respective telescopic cylinders, the withstand voltage test device can be connected to multiple stations and can simultaneously measure multiple injection molded copper busbars and other products. The multiple test stations connected in parallel can perform withstand voltage tests simultaneously or separately, and thus the location of defective products in the test results can be identified, thereby improving the test efficiency and test application diversity of the withstand voltage test device.
