Description

Technical Field

[0001] This utility model relates to the field of wiring harness testing, and in particular to a wiring harness testing device for automotive side 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 side 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.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A vehicle side air vent wiring harness testing device includes a base, on which are mounted a first fixed platform, a second fixed platform, and a testing platform. The first fixed platform has a first fixed groove, into which the terminals of the wiring harness to be tested are inserted. The second fixed platform is located in front of the first fixed platform and has two wire slots. Two wires connected from the terminals are respectively inserted into the two wire slots. A visual inspection device is embedded in the second fixed platform. A visual hole is opened in the middle of each of the two wire slots, through which the visual inspection device performs visual inspection on the two wires. The other ends of the two wires are connected to a PCB board, on which LED lights are installed. A detection hole is opened on the detection platform, and the detection hole is consistent with the shape of the PCB board. A photosensitive sensor is installed inside the detection hole.

[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.

[0009] Preferably, an alarm is provided on the base.

[0010] The beneficial effects of this utility model are as follows: by combining the wire sequence results detected by the visual inspection equipment and the results of whether the LED light is emitting light detected by the photosensitive sensor, and by referring to the voltage at both ends of the wire and the current passing through the wire at this time, the system comprehensively judges whether the connection of the tested wire harness is correct and whether the wire harness is qualified, thereby ensuring the quality of the wire harness.

[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 1 As shown, a vehicle side air vent wiring harness testing device mainly includes a base 1, on which a fixing platform 2, a fixing platform 3, and a testing platform 4 are arranged in a linear manner to facilitate the fixing and testing of the wiring harness.

[0015] The mounting platform 2 is located behind the base 1 and has a mounting slot 5. The upper opening of the mounting slot 5 matches the terminal of the wire harness under test, facilitating the insertion and fixation of the terminal from above. The front opening of the mounting slot 5 is smaller than the size of the terminal, preventing the terminal from accidentally falling off during testing and ensuring connection stability. After the terminal of the wire harness under test is inserted into the mounting slot 5, the two wires of the wire harness extend forward from the front opening of the mounting platform 2.

[0016] Fixing platform 2 (3) is located in front of fixing platform 1 (2). Fixing platform 2 (3) has two parallel wire grooves (6), each used to hold one wire. The size of the wire grooves (6) is adapted to the diameter of the wire to ensure that the wire can be tightly held in place.

[0017] The fixed platform 2 3 is equipped with a visual inspection device. The visual inspection device uses a camera or image sensor. A visual hole 7 is opened in the middle of each of the two wire slots 6. The visual hole 7 is aligned with the visual inspection device, so that the visual inspection device can visually identify the two wires stuck in the wire slots 6 through the visual hole 7, detect the color or marking of the wires, and thus determine whether the wire sequence is correct.

[0018] To further secure the wire, an electromagnetic lock 9 is installed on the upper surface of the second fixing platform 3, and a fixing plate 10 is also installed on one side of the second fixing platform 3. One side of the fixing plate 10 is rotatably connected to the second fixing platform 3 via a rotating rod. After the wire is inserted into the wire groove 6, the fixing plate 10 is rotated to cover the wire groove 6 and press the wire down. Then the electromagnetic lock 9 is activated to lock the fixing plate 10, preventing the wire from shifting or loosening during the testing process.

[0019] The other ends of the two wires are connected to a PCB board, which integrates LEDs. These LEDs serve as indicators to verify the continuity of the wiring harness. This PCB board can then be directly connected to the corresponding circuit in the vehicle.

[0020] The testing platform 4 is located in front of the fixed platform 3. The testing platform 4 has a testing hole 8, the shape of which matches the PCB board for easy insertion. A photosensitive sensor is installed inside the testing hole 8, aligned with the LED position on the PCB board. When the wiring harness is powered on, if the wiring sequence is correct and the connection is good, the LED should light up normally. After the photosensitive sensor detects the light signal, it outputs the testing result.

[0021] The base 1 is also equipped with two displays 11, which are used to display the voltage value and the current value through the wire in real time during the detection process, so that the operator can monitor the detection status.

[0022] In addition, an alarm 12 is installed on the base 1. When the visual inspection device detects a wiring error or the photosensitive sensor fails to detect the LED light illuminating, the alarm 12 will sound an audible and visual alarm to indicate a detection failure. When a failed product is detected, it must be placed in a dedicated recycling bin before the alarm 12 will stop.

[0023] Working principle: First, insert the wiring terminals of the wire harness into the fixing slot 5 of fixing platform 2. Then, insert the two wires into the wire slot 6 of fixing platform 3 respectively, and fix them with fixing plate 10 and electromagnetic lock 9. The visual inspection equipment automatically detects the wire sequence.

[0024] Simultaneously, the PCB board is inserted into the detection hole 8 of the detection station 4, and the photosensitive sensor detects whether the LED light is emitting light. Combined with the visual inspection results, the connection of the wire harness is comprehensively judged to ensure the quality of the wire harness.

[0025] 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.
