[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figures 1-5 An automatic testing device for a wire harness system in this embodiment includes a testing platform 1. A testing panel 2 is fixedly installed on the outer surface of the testing platform 1. One side of the testing platform 1 is inclined. The testing panel 2 is installed on the inclined surface of the testing platform 1. Several large wire harness testing plates 3, small wire harness testing plates 4, wire harness sleeve testing plates 5, wire harness insertion testing plates 6, letter positioning plates 8, and number positioning plates 9 are fixedly installed on the upper end of the testing panel 2. The letter positioning plates 8 are installed in the longitudinal edge area of ​​the upper end of the testing panel 2, and the number positioning plates 9 are installed in the transverse edge area of ​​the upper end of the testing panel 2.

[0025] When testing a multi-wire harness system, the corresponding testing board is first located according to the interface number on each wire harness testing board. Then, the wire harness to be tested is connected to different testing boards, which solves the problem of testing multiple wire harness models. During testing, when an abnormal wire harness is detected, the digital positioning board 9 and the letter positioning board 8 on the testing panel 2 realize the rapid positioning of the wire harness through the horizontal and vertical coordinates, reducing the fault location time.

[0026] A fixing plate 11 is fixedly installed on the upper end of the large wire harness detection board 3. A large wire harness insertion hole 10 is opened on the upper surface of the large wire harness detection board 3. A fixing strip 12 is fixedly installed on the upper end of the fixing plate 11. At least two rotating pieces 13 are rotatably installed on one side of the fixing strip 12. The rotating pieces 13 are located outside the fixing strip 12 and the two rotating pieces 13 are fixedly connected. A rotating column 16 is rotatably installed between the two rotating pieces 13. The rotating column 16 is also rotatably installed on the other side of the fixing strip 12. A hollow column 20 is fixedly installed on the upper end of the rotating column 16. A spiral rod 18 is installed inside the hollow column 20. The spiral rod 18 extends to the outside of the hollow column 20 and is threadedly engaged with the hollow column 20. A fixing column 19 is fixedly installed on one end of the spiral rod 18.

[0027] When the large wire harness is positioned on the large wire harness detection board 3 according to the interface number on the wire harness board, the wire harness is inserted into the large wire harness socket 10. The connection of the wire harness is detected by sending an electrical signal. At this time, the rotating plate 13 and the rotating column 16 on the fixing plate 11 are rotated. The rotation of the rotating column 16 will drive the spiral rod 18 and the fixing column 19 to move. The large wire harness is fixed by pressing the wire harness through the fixing column 19.

[0028] The upper surface of the small wire harness detection board 4 is provided with a small wire harness insertion hole 21. A fixing plate 22 is fixedly installed on the upper end of the small wire harness detection board 4. A sliding space 23 is provided inside the fixing plate 22. The sliding space 23 extends to the outside of the fixing plate 22. A fixing block 24 is slidably installed inside the sliding space 23. At least two sliding brackets 25 are fixedly installed on the outside of the fixing block 24. At least two sliding grooves 26 are provided on the inner wall of the sliding space 23. One end of the sliding bracket 25 is slidably installed inside the sliding groove 26. A spring 27 is fixedly installed inside the sliding space 23. One end of the spring 27 is fixedly connected to the fixing block 24, and the other end is fixedly connected to the inner wall of the sliding space 23.

[0029] When the miniature wire harness is positioned on the miniature wire harness detection board 4 according to the interface number on the wire harness board, the wire harness is inserted into the miniature wire harness socket 21. The connection of the wire harness is detected by sending an electrical signal. Because part of the fixing block 24 is placed above the miniature wire harness socket 21, when the wire harness is inserted, the fixing block 24 needs to be squeezed. The fixing block 24 will squeeze the spring 27 and move along the slide groove 26 into the sliding space 23 until the miniature wire harness socket 21 is fully exposed. The wire harness is inserted into the miniature wire harness socket 21. At this time, the fixing block 24 is affected by the spring 27 and generates a pushing force on the wire harness, thereby achieving the effect of fixing the wire harness.

[0030] The upper end of the wire harness sleeve detection plate 5 is fixedly provided with a detection post 28 and a sleeve power-conducting post 20. A sleeve power-conducting post 29 is provided through the inside of the detection post 28 and extends to the outside of the detection post 28.

[0031] When the wire harness is positioned on the wire harness mounting detection board 5 according to the interface number on the wire harness board, the wire harness is fitted into the mounting power-conducting post 29 and the mounting power-conducting post 30. The mounting power-conducting post 29 and the mounting power-conducting post 30 contact the wire harness terminals and send an electrical signal to detect whether the wire harness is connected. The fitting method will use gravity to fix the wire harness.

[0032] The upper surface of the wire harness insertion detection board 6 is provided with a wire harness insertion hole 33, and a plug plate 31 is fixedly provided on the upper end of the wire harness insertion detection board 6. The upper surface of the plug plate 31 is provided with at least two insertion holes 32.

[0033] When the wire harness is positioned on the wire harness plug-in detection board 6 according to the interface number on the wire harness board, the wire harness is inserted into the wire harness plug-in hole 33. The connection of the wire harness is detected by sending an electrical signal. At the same time, another part of the wire harness is inserted into the plug-in board 31 through the plug-in hole 32 to achieve the effect of fixing the wire harness.

[0034] A wire harness detection display 7 is fixedly installed on the upper end of the testing station 1. The wire harness detection display 7 is connected to each wire harness detection board to receive and display the test data.

[0035] When all the wire harnesses are connected to the corresponding wire harness detection board, the wire harness detection display 7 will display the test results of each wire harness and the corresponding coordinates of the faulty wire harness. At this time, the digital positioning board 9 and the letter positioning board 8 on the detection panel 2 can be used to quickly locate the fault and reduce the fault location time.

[0036] The circuit connection and the display of the corresponding coordinates of the faulty wire harness by the wire harness detection display instrument 7 are common technologies. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in this field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
