[0001] This utility model relates to the field of wiring harness testing, and in particular to a device for testing wiring harnesses for automotive air vents. Background Technology

[0002] Automotive wiring harnesses connect the entire vehicle body and form the main network of automotive circuits. A wiring harness is a component that connects circuits by crimping copper contact terminals with wires and cables, then molding an insulator or adding an outer metal shell, and bundling the wires together.

[0003] To ensure the proper functioning of automobiles, every automotive wiring harness produced must be tested. Testing typically checks for continuity and whether the harness fulfills its intended function. Wiring harnesses used in the side air vents of automobiles must have correct wiring sequence and proper continuity. Finding a simple and convenient way to perform this testing has been a continuous research and development direction. To address the above issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle air vent wiring harness detection device, which has the advantage of being able to detect the wiring sequence and the continuity function of the wiring harness at the same time.

The wiring harness under test includes a terminal block, two first wires, two second wires, a PCB board, and a resistive element. One end of each of the four wires is connected to the terminal block, the other end of the two first wires is connected to the PCB board, and one end of the two second wires is connected to the resistive element. The base is provided with a first fixed platform, a second fixed platform, a testing platform, and a resistance testing fixture. The first fixed platform has a first fixed groove, into which a terminal block is inserted. The second fixed platform is located in front of the first fixed platform and has two wire grooves. Two wires are respectively inserted into the two wire grooves. The second fixed platform is embedded with a visual inspection device. A visual hole is opened in the middle of each of the two wire grooves. The visual inspection device performs visual inspection on the two wires through the visual hole. The PCB board is equipped with LED lights, and the detection platform has a detection hole with the same shape as the PCB board. A photosensitive sensor is installed inside the detection hole. The resistance test fixture is connected to an external resistance detector. The resistance test fixture has a plug-in hole, the size of which matches the resistance element. The resistance element is plugged into the plug-in hole to perform resistance testing on the resistance element.

[0006] Preferably, the upper opening of the fixing groove is matched with the size of the terminal block, and the front opening of the fixing groove is smaller than the size of the terminal block.

[0007] Preferably, the upper end face of the second fixing platform is provided with an electromagnetic lock, and a fixing plate is also provided on one side of the second fixing platform. One side of the fixing plate is rotatably connected to the second fixing platform via a rotating rod. The fixing plate is used to fix the wire in the wire groove, and the electromagnetic lock is used to lock the fixing plate.

[0008] Preferably, the base is also provided with two display screens, which are used to display the voltage during detection and the current passing through the wire, respectively.

[0013] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0014] like Figure 1As shown, a testing device for automotive air vent wiring harness mainly includes a base 1, which serves as the supporting foundation for the entire device. A first fixed platform 2, a second fixed platform 3, a testing platform 4, and a resistance testing fixture 5 are mounted on the base 1. The wiring harness under test includes terminals, two first wires, two second wires, a PCB board, and a resistive element. One end of each of the four first wires is connected to the terminals, the other end of the two first wires is connected to the PCB board, and one end of the two second wires is connected to the resistive element.

[0015] The mounting platform 2 is mounted on the base 1, and a mounting groove 6 is provided on its upper part. The mounting groove 6 is designed to match the size of the wiring terminal, allowing the wiring terminal to be vertically inserted into the mounting groove 6. The upper opening of the mounting groove 6 is sized to match the wiring terminal for easy insertion and fixation, while the front opening of the mounting groove 6 is smaller than the size of the wiring terminal to prevent the wiring terminal from coming out from the front, ensuring stable insertion of the wiring terminal during testing.

[0016] Fixing platform 2 (3) is located in front of fixing platform 1 (2). The upper surface of fixing platform 2 (3) has two wire grooves (7) for securing two wires (1). Fixing platform 2 (3) is internally equipped with visual inspection devices, such as cameras or image sensors. Visual inspection holes (8) are provided in the center of each of the two wire grooves (7). The visual inspection devices use these visual holes (8) to capture images of the wires, detecting their color, wiring sequence, or appearance, thereby determining whether the wire connection is correct.

[0017] To secure the wire, an electromagnetic lock 11 is installed on the upper surface of the second fixing platform 3. A fixing plate 12 is rotatably connected to one side of the second fixing platform 3 via a rotating rod. The fixing plate 12 can cover the wire groove 7 and press the wire tightly into the wire groove 7. The electromagnetic lock 11 is used to lock the fixing plate 12 when it is closed to prevent the wire from moving during the testing process.

[0018] The testing platform 4 has a testing hole 9, the shape of which matches the PCB board, allowing the PCB board to be accurately placed inside. An LED is mounted on the PCB board, and a photosensitive sensor is installed inside the testing hole 9. When the PCB board is placed in the testing hole 9, the photosensitive sensor detects whether the LED is lit, thus verifying the continuity of the first wire and whether the LED is functioning correctly.

[0019] The resistance test fixture 5 is also mounted on the base 1 and connected to an external resistance detector, such as a multimeter. The resistance test fixture 5 has a plug-in hole 10, the size of which matches the resistance element. The resistance element can be inserted into the plug-in hole 10. The resistance value of the resistance element is measured by the resistance test fixture 5 and the external resistance detector to ensure that the resistance element meets the specifications.

[0020] In addition, two displays 13 are installed on the base 1, which are used to display the voltage value and the current value through the wire in real time during the testing process, so that the operator can easily monitor the testing status. An alarm 14 is also set on the base 1. When an incorrect wiring sequence, LED light not lit, or abnormal resistance value is detected, the alarm 14 will sound an alarm to indicate that the wiring harness is defective.

[0021] When a failed product is detected, it must be placed in a dedicated recycling bin before the alarm 14 will stop.

[0022] The workflow of the entire device is as follows: First, insert the terminal block into the fixing slot 6 of the fixing platform 12, then insert the two wires into the wire slot 7 of the fixing platform 23 and press them with the fixing plate 12, and check the wire sequence through the visual inspection equipment. Then the PCB board is placed into the detection hole 9 of the detection stage 4, and the LED light emission status is detected by the photosensitive sensor; Simultaneously, the resistive element is inserted into the insertion hole 10 of the resistance test fixture 5 for resistance testing; By combining the voltage and current data displayed on the screen 13, the correctness of the wiring harness connection and the integrity of its functions are comprehensively determined, and the test results are finally fed back through the alarm 14. This application realizes rapid and comprehensive testing of the wiring harness, ensuring the quality of the wiring harness.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
