[0016] Embodiment: A wire processing detection auxiliary jig includes a jig plate 1, a terminal buckle 2, a vibrator 3, a resistance detector 4, a resistance analysis device 5, a controller, a test result output device 7 and a power supply. Two groups of terminal buckles 2 are fixedly installed on the jig plate 1 at intervals. The vibrator 3 is fixedly installed on the jig plate 1 and can drive the jig plate 1 to vibrate. The controller can control the start and stop and vibration frequency of the vibrator 3. The resistance detector 4 is electrically connected and communicated with the resistance analysis device 5. The resistance analysis device 5 is electrically connected and communicated with the test result output device 7. The two groups of terminal buckles 2 are respectively connected in series with the resistance detector 4 through wires. The continuous end connectors 81 at both ends of the wire to be tested 8 can be plugged and connected with the two groups of terminal buckles 2 in a one-to-one correspondence, so that the wire to be tested 8 and the resistance detector 4 form a series circuit. The power supply supplies power to the series circuit. 4 can output the resistance value detected by it to the resistance analysis device 5. The resistance detector 4 can detect the resistance value of the series circuit. The resistance analysis device 5 includes a preset data input module, a data receiving module, a data storage module and a data comparison and analysis module. The preset data input module is electrically connected and communicates with the data storage module. The data storage module can store preset data input by the preset data input module. The data receiving module can receive real-time resistance detection data transmitted by the resistance detector 4.

The data comparison and analysis module can output the comparison and analysis results to the test result output device 7. The test result output device 7 can output the detection data of the tested wire 8.

[0017] When testing the wire harness, place the entire bundle of wires on the jig plate 1, and connect the continuous end connectors 81 at both ends of the wires to the terminal buckles 2 on the jig plate 1. Then start the vibrator 3 to make the jig plate 1 vibrate to simulate the vibration of industrial equipment. Then turn on the power start switch, and the resistance detector 4 begins to detect the resistance of the line and feeds back the real-time detected resistance value to the resistance analysis device 5. The resistance analysis device 5 compares the real-time resistance value with the upper and lower limits of the pre-stored resistance fluctuation range. During the continuous vibration process, the continuous end connector 81 that is poorly crimped may have problems such as momentary disconnection. This problem will be reflected in the change of resistance. It can be found in the resistance analysis device 5 that when the resistance change fluctuation exceeds the set resistance fluctuation range, it means that the continuous end connector 81 of the wire is poorly crimped. This test result will be displayed by the test result output device 7 of the detector.

[0018] The fixture plate 1 is located between the two sets of terminal buckles 2 and is further provided with a wire harness receiving groove 9 , in which the wires 8 to be tested can be received. The vibrator 3 is fixed at the bottom of the wire harness receiving groove 9 .

[0019] During testing, the entire bundle of wires is placed in the wire harness receiving groove 9, with both ends of the wires extending out of the wire harness receiving groove 9 and connected to the terminal buckle 2. The vibrator 3 vibrates at the bottom of the wire harness receiving groove 9. On the one hand, it can fully simulate the vibration working conditions of the wires, and on the other hand, it can prevent the wires from being vibrated and moving around on the jig plate 1, causing tangled chaos.

[0020] A wire harness device is also provided, which can be fixedly connected to both sides of the wire harness receiving slot 9. The wire harness device can cover the opening of the digital display receiving slot to prevent the wires being tested in the digital display receiving slot from escaping the wire harness receiving slot 9.

[0021] The harness device is a cover plate that is snap-fitted to the fixture plate 1 on both sides of the harness receiving groove 9 or a magic adhesive harness tape fixed to the two side walls of the harness receiving groove 9. In addition, other structures can also be used to block the harness.

[0022] The fixture plate 1 includes a fixed plate 10, a movable plate 11 and a locking device 15. The fixed plate 10 is provided with a linear guide rail 12. The movable plate 11 can be installed on the fixed plate 10 by sliding along the linear guide rail 12. The fixed plate 10 is formed with a first groove that is open both above and below the movable plate 11. The movable plate 11 is formed with a second groove that is open both above and toward the fixed plate 10. The first groove and the second groove are spliced together to form a wire harness receiving groove 9. The length of the wire harness receiving groove 9 can be changed as the movable plate 11 slides. The locking device 15 can lock the movable plate 11 at any position into position with the fixed plate 10. Two sets of terminal buckles 2 are respectively provided on the fixed plate 10 and the movable plate 11. By sliding the movable plate 11 on the fixed plate 10 along the linear guide rail 12, the length of the wire harness receiving groove can be changed, thereby adapting to the detection of wires of different lengths.

[0023] A high-voltage tester 6 is also provided. The high-voltage tester 6 and the resistance detector 4 are connected in parallel. The high-voltage tester 6 is electrically connected and communicated with the test result output device 7. The high-voltage tester 6 can apply a high voltage higher than the working voltage to the series circuit where the test wire 8 is located. The high-voltage tester 6 can detect the leakage current of the series circuit and judge the high-voltage resistance of the test wire 8 according to the magnitude of the leakage current. The high-voltage tester 6 can transmit its detection data to the test result output device 7. While detecting the crimping condition of the continuous end connector 81 of the wire, the wiring harness is also tested for high-voltage resistance through the high-voltage tester 6 to prevent voltage breakdown during use.

[0024] There is also a connector pin detection device 13, which is connected in parallel with the resistance detector 4. The connector pin detection device 13 is provided with several groups of SOT signal pins. The pin positions of each group of SOT signal pins are different from each other. Each group of SOT signal pins is electrically connected and conductive with each group of terminal buckles 2.

The connector pin detection device 13 is electrically connected and communicates with the test result output device 7. The test result output device 7 can display information on whether the connector pins of the test harness are connected incorrectly. When the harness is tested, the connector pin detection device 13 is used to detect whether there is any misalignment when the harness is plugged into the terminal buckle 2. If there is any misalignment, the circuit corresponding to the connector pin detection device 13 cannot form an SOT signal. This device can prevent the connector pins of the harness from being connected incorrectly during testing, which may cause false detection.

[0025] An alarm 14 is also provided. The alarm 14 is electrically connected to the test result output device 7 and can send different alarms based on the detection information output by the test result output device 7. When an error or defect occurs during the detection process, the alarm will promptly issue an alarm based on the test result to facilitate workers to promptly discover it.
