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 high-end wiring harness testing device for automotive side air vents, which has the advantage of being able to test the wiring harness continuity function while testing the wiring sequence.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A testing device for high-voltage wiring harnesses in automotive side air vents includes a base. The wiring harness under test includes three wires, a terminal block, and two PCBs. Two of the wires have one end connected to the terminal block and the other end connected to one PCB, respectively.

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, and 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.

[0006] Preferably, a stop block is provided on the first fixed platform, the stop block is located on one side of the first fixed groove, the stop block is provided with a retaining groove, the width of the retaining groove is less than the width of the first fixed groove, and the depth of the retaining groove is less than the height 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, there are two detection holes, each containing a photosensitive sensor, and the size and shape of the two detection holes are respectively matched with the size and shape of the two PCB boards.

[0014] 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.

[0015] like Figure 1As shown, a high-power wiring harness testing device for automotive side air vents mainly includes a base 1, on which are mounted a first fixing platform 2, a second fixing platform 3, and a testing platform 4, arranged linearly to facilitate the fixing and testing of the wiring harness. The wiring harness under test includes three wires, a terminal block, and two PCBs. One end of two of the wires is connected to the terminal block, and the other end is connected to one PCB. The two ends of the third wire are connected to both PCBs, i.e., the two PCBs are connected in series.

[0016] The mounting platform 2 is located on the rear side of the base 1, and a mounting groove 5 is provided on it. The size of the mounting groove 5 matches the size of the end of the wiring terminal, so that the wiring terminal can be inserted from above.

[0017] A stop block 9 is provided on the fixed platform 2, located in front of the fixed groove 5. The stop block 9 has a retaining groove 10, the width of which is smaller than the width of the fixed groove 5. The tail of the terminal block is smaller than its end, allowing it to snap into the retaining groove 10. The depth of the retaining groove 10 is less than the height of the terminal block, facilitating the placement and removal of the terminal block. The step difference between the retaining groove 10 and the fixed groove 5 prevents the terminal block from accidentally falling off during testing, ensuring connection stability.

[0018] 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.

[0019] 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.

[0020] To further secure the wire, an electromagnetic lock 11 is provided on the upper surface of the second fixing platform 3, and a fixing plate 12 is also provided on one side of the second fixing platform 3. One side of the fixing plate 12 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 12 is rotated to cover the wire groove 6 and press the wire down. Then the electromagnetic lock 11 is activated to lock the fixing plate 12, preventing the wire from shifting or loosening during the testing process.

[0021] The two PCBs are designated Board 1 and Board 2, and the three wires are designated Wire 1, Wire 2, and Wire 3. One end of Wire 1 and Wire 2 is connected to a terminal block, and the other end is connected to Board 1 and Board 2 respectively. Wire 3 is connected to both PCBs. Therefore, the wires to be tested here are Wire 1 and Wire 3. The PCBs integrate LEDs, which act as indicators to verify the continuity of the wiring harness. Afterward, this PCB can be directly connected to the corresponding circuit in the vehicle.

[0022] The testing platform 4 is located in front of the fixed platform 3. Two testing holes 8 are provided on the testing platform 4, each with a shape consistent with one of the two PCB boards for easy insertion. A photosensitive sensor is installed inside each 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 test result.

[0023] The base 1 is also equipped with two displays 13, 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.

[0024] In addition, an alarm 14 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 14 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 14 will stop.

[0025] Working principle: First, insert the wiring terminals of the wire harness into the fixing slot 5 of the fixing platform 12, and snap the tail of the wiring terminal into the retaining slot 10. Then, snap wire 1 and wire 3 into the wire slot 6 of the fixing platform 2, and fix them with the fixing plate 12 and electromagnetic lock 11. The visual inspection equipment automatically detects the wire sequence.

[0026] At the same time, the two PCB boards are inserted into the corresponding detection holes 8. The photosensitive sensor detects whether the LED light is emitting light. Combined with the visual inspection results, the connection of the wire harness is judged to be correct, thereby ensuring the quality of the wire harness.

[0027] 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.
