Description

Technical Field

[0001] This utility model relates to the field of resistance testing technology, specifically a high-voltage energy storage harness resistance testing device. Background Technology

[0002] During the production and testing process, some high-voltage energy storage harnesses, such as charging cables for new energy vehicles and other harnesses used for power transmission, undergo resistance testing. The resistance of high-voltage energy storage harnesses directly affects the current transmission efficiency. Excessive resistance can lead to increased power loss, potentially causing the harness to overheat or even melt, affecting system stability and safety. Therefore, resistance testing of high-voltage energy storage harnesses is essential.

[0003] In existing technologies, when conducting resistance tests on high-voltage energy storage harnesses, it is usually necessary to manually insert the high-voltage energy storage harness into the connection circuit before powering on for testing. This makes it impossible to control the automatic power-on operation of the high-voltage energy storage harness. Furthermore, in some high-voltage energy storage harness resistance testing devices, the resistance testing components are exposed to the outside environment. Although personnel are kept away from the testing components during the testing process, if a short circuit occurs in the high-voltage energy storage harness, the high-voltage energy storage harness or the testing components may explode, which still affects the safety of the testing personnel and poses a certain degree of danger.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a high-voltage energy storage harness resistance testing device includes a resistance testing platform 1. A display screen 2 for displaying the test status is installed in the middle of the resistance testing platform 1. A base plate 3 is fixedly installed on the worktable of the resistance testing platform 1. A power connection component 4 is installed at one end of the base plate 3. A wire placement frame 5 is slidably installed in the middle of the base plate 3. Wire placement grooves 6 are formed at both ends of the wire placement frame 5 corresponding to the positions of the power connection component 4. An electric push rod 7 for driving the wire placement frame 5 to move is fixedly installed in the middle of the base plate 3. Isolation covers 8 are symmetrically slidably installed on the worktable of the resistance testing platform 1. The two isolation covers 8 are close to each other to seal the power connection component 4. Guide rods 18 are symmetrically fixedly installed at the two guide rods 18. The isolation cover 8 is slidably installed between the two guide rods 18. The two ends of the high-voltage energy storage wire harness are placed inside the two wire slots 6 at the end of the wire rack 5, and the ends of the high-voltage energy storage wire harness are pressed tightly against the ends of the wire slots 6. Then, the two isolation covers 8 are moved closer to each other. The isolation covers 8 will isolate and seal the components such as the closed power connection component 4 on the base plate 3. The power connection component 4 is energized and operated. The personnel move away from the resistance test platform 1. Then, the personnel control the electric push rod 7 to operate. The electric push rod 7 drives the wire rack 5 to move and insert the two ends of the high-voltage energy storage wire harness on the wire rack 5 into the power connection component 4 to realize the resistance test of the high-voltage energy storage wire harness. The resistance test process and results will be displayed on the display screen 2.

[0022] like Figures 1 to 4 As shown, guide rails 9 are symmetrically fixedly installed on both sides of the base plate 3, the wire rack 5 is slidably installed between the two guide rails 9, a connecting frame 10 is fixedly installed on one side of the wire rack 5, and the moving end of the electric push rod 7 is fixedly connected to the connecting frame 10.

[0023] The operation of the electric push rod 7 can drive the wire rack 5 to move along the trajectory of the two guide rails 9.

[0024] like Figures 1 to 4As shown, a fixed plate 11 is slidably mounted on the top of the cable holder 5. The two ends of the fixed plate 11 are set corresponding to the cable slots 6. A sliding hole 12 is symmetrically opened in the middle of the cable holder 5. A sliding rod 13 is slidably mounted inside the sliding hole 12. The tops of the two sliding rods 13 are fixedly connected to the middle of the fixed plate 11. A spring 14 is sleeved on the outer side of the top of the sliding rod 13. One end of the spring 14 is fixedly connected to the fixed plate 11, and the other end of the spring 14 is fixedly connected to the cable holder 5. A right-angled triangular block 15 is fixedly mounted at the bottom of the two sliding rods 13. A right-angled trapezoidal block 16 is fixedly mounted in the middle of the base plate 3 corresponding to the position of the right-angled triangular block 15. The hypotenuse of the right-angled trapezoidal block 16 is in contact with the hypotenuse of the right-angled triangular block 15.

[0025] During the process of moving the high-voltage energy storage harness and connecting the power assembly 4, the spring 14 on the wire rack 5 will continuously pull the fixing plate 11. Since the hypotenuse of the right-angled trapezoidal block 16 and the hypotenuse of the right-angled triangular block 15 are always in contact, the right-angled triangular block 15 will descend when the wire rack 5 moves, which will drive the fixing plate 11 indirectly connected to the right-angled triangular block 15 to descend until the fixing plate 11 presses and fixes the high-voltage energy storage harness inside the wire rack 6.

[0026] like Figures 1 to 4 As shown, a magnet 17 is fixedly installed at a position close to the top of the isolation cover 8.

[0027] When the two isolation covers 8 are brought close to each other, they are magnetically fixed by two magnets 17 on the top of the two isolation covers 8, which can be used to close the two isolation covers 8.

[0028] like Figures 1 to 4 As shown, grating assemblies 19 are installed on both sides of the resistance test stage 1.

[0029] The grating assembly 19 can be used to monitor whether personnel are still inside the resistance testing station 1.

[0030] This utility model provides a high-voltage energy storage harness resistance testing device, the specific working principle of which is as follows:

[0031] When using the device, place both ends of the high-voltage energy storage harness inside the two wire slots 6 at the end of the wire holder 5, and press the ends of the high-voltage energy storage harness tightly against the ends of the wire slots 6. Then, move the two isolation covers 8 closer together along the tracks of the two guide rods 18, and fix them together by magnetic attraction between the two magnets 17 on the top of the two isolation covers 8. This is used to isolate and seal the components such as the closed connection assembly 4 on the base plate 3. After the connection assembly 4 is energized, the personnel move away from the resistance test platform 1. Then, the personnel control the electric push rod 7 to operate. The electric push rod 7 drives the wire holder 5 to move along the tracks of the two guide rails 9, inserting both ends of the high-voltage energy storage harness on the wire holder 5 into the connection assembly 4 to realize the resistance test of the high-voltage energy storage harness. The resistance test process and results will be displayed on the display screen 2. In the middle, the spring 14 on the wire placement frame 5 will continuously pull the fixing plate 11. Since the hypotenuse of the right trapezoid block 16 and the hypotenuse of the right triangle block 15 are always in contact, the right triangle block 15 will descend when the wire placement frame 5 moves, which will drive the fixing plate 11 indirectly connected to the right triangle block 15 to descend until the fixing plate 11 squeezes and fixes the high-voltage energy storage wire bundle inside the wire placement groove 6. After the test is completed, the electric push rod 7 drives the wire placement frame 5 to move in the opposite direction along the trajectory of the two guide rails 9, and pulls the two ends of the high-voltage energy storage wire bundle on the wire placement frame 5 out of the power connection component 4. During the movement of the wire placement frame 5, the hypotenuse of the right trapezoid block 16 will squeeze the hypotenuse of the right triangle block 15, which will drive the fixing plate 11 indirectly connected to the right triangle block 15 to rise, which is used to cancel the squeezing and fixing of the high-voltage energy storage wire bundle inside the wire placement groove 6 by the fixing plate 11.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
