[0002] The main purpose of the tensile test of the connector of the power system of new energy vehicles is to evaluate the strength and reliability of the connector when subjected to tension. Through the test, it can be ensured that the connector can withstand the expected tension in the power system, thereby avoiding safety hazards caused by connector breakage or failure during vehicle operation.

[0003] When conducting tensile tests on connectors for new energy vehicle power systems, tensile testing equipment is often used.

In addition, the integrated type is adopted to improve the test efficiency and reduce the cost.

[0055] Working principle: When conducting a tensile test, the two ends of the sample are placed between the two clamping assemblies 202, and the handle 2023 is turned, so that the handle 2023 drives the screw rod 2022 to rotate, and the screw rod 2022 and the threaded barrel 2024 are threadedly transmitted, so that the threaded barrel 2024 drives the movable plate 2025 to move, and the movable plate 2025 drives the assembly frame 2026 to move, and the assembly frame 2026 drives the clamping member 2027 to clamp and fix the end of the sample;

[0056] After the two ends of the sample are fixed, the motor 3015 drives the stud 3012 to rotate, and the stud 3012 drives the nut 3013 to move upward, so that the nut 3013 drives the fixing plate 3021 to move, and the fixing plate 3021 drives the first positioning sleeve 3039 and the bracket 3031 to move upward through the sliding rod 3024, and the bracket 3031 drives the rotating member 3034 and the monitoring structure 304 to move through the rotating shaft 3032, so that the monitoring structure 304 applies an upward force to the clamping component 202. At this time, the clamping component 202 can apply an upward force to the sample, so that the sample can be subjected to a tensile test, and the data of the tensile process is transmitted to the testing device 100 through the monitoring structure 304. At the same time, the two ends of the wire can also be directly clamped on the upper and lower clamping components 202, and the tensile test is performed according to the above steps;

[0057] When the bending tensile test of the wire is required, first remove the bolts of the adjustment sleeve 2012, and pull the adjustment column 2014 through the handle 2015, so that the adjustment column 2014 drives the clamping assembly 202 below to move to the left, and then fix the position of the adjustment column 2014 with bolts;

[0058] Then, the fixing bolt 3035 is rotated to disengage from the fixing opening 3038, and the disc 3037 is rotated, so that the disc 3037 drives the rotating shaft 3032 to rotate, and the rotating shaft 3032 drives the rotating member 3034 to rotate, so that the rotating member 3034 drives the upper clamping assembly 202 to flip upward and keep it upright through the monitoring structure 304, and after adjustment, the fixing bolt 3035 is screwed into the fixing opening 3038 for fixing;

[0059] After the clamping assembly 202 is flipped and adjusted, the operating handle 3025 is pulled again, so that the operating handle 3025 drives the spring 3023 to deform, so that the operating handle 3025 drives the slide bar 3024 to separate from the first positioning sleeve 3039, and the bolts of the first movable sleeve 3033 are removed, and the position of the bracket 3031 is adjusted downward, so that the adjustment assembly 303 drives the upper clamping assembly 202 to move downward and move to the lower part of the clamping assembly 202, and then the position of the first movable sleeve 3033 is fixed by bolts;

[0060] Then, the bolts on the second movable sleeve 3054 are removed, and the position of the mounting member 3053 is adjusted downward to adjust the test wheel 3051 to a suitable position, and then the position of the second positioning sleeve 3055 is fixed by bolts. At the same time, the operating handle 3025 is reset by the reset force of the spring 3023, and the slide bar 3024 is reset. The slide bar 3024 is engaged in the second positioning sleeve 3055. At this time, the wire is passed around the test wheel 3051, and both ends are placed between the clamping members 2027. Then, the clamping assembly 202 fixes the wire. After fixation, the wire assembly assembly 305 can be pulled upward by the tensile test assembly 301 again to perform the wire bending tensile test.

[0061] When the bending and tensile position of the wire rod needs to be adjusted, the upper and lower positions of the clamping assembly 202 are adjusted through the adjusting assembly 303, so as to adjust the bending and tensile position of the wire rod.

[0062] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
