Technical Field

[0001] This utility model relates to the field of wire harness testing, and in particular to a wire harness testing device for B-pillar light-emitting modules. 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 B-pillar light-emitting module 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 B-pillar light-emitting module wiring harness testing device includes a base and a wiring harness under test. The wiring harness under test includes a terminal block, two wires, and a PCB board. One end of the two wires is connected to the terminal block, and the other end of the two wires is connected to a circuit on the PCB board. An LED light is installed on the PCB board. The base is provided with a first fixed platform, a second fixed platform, and a testing platform. The first fixed platform is provided with a first fixed groove, into which the terminals of the wire harness to be tested are inserted. The second fixed platform is located in front of the first fixed platform and is provided with two wire grooves. Two wires are respectively inserted into the two wire grooves. 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 grooves. The visual inspection device performs visual inspection on the two wires through the visual hole. The testing platform has a testing hole, which is the same shape as the PCB board, and a photosensitive sensor is installed inside the testing hole.

[0006] Preferably, the opening of the fixing groove is matched with the size of the wiring terminal, and the fixing groove is set obliquely upward.

[0007] Preferably, the upper surface 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, and the other side of the fixing plate is provided with a locking groove. The fixing plate is used to fix the wire in the groove, and the electromagnetic lock is used to lock the fixing plate.

[0008] Preferably, one end of the wire groove is provided with a wire harness groove, where two wires are fixed into a wire harness segment by an insulating sleeve. The wire harness segment is snapped into the wire harness groove. A push switch is provided in the wire harness groove, and the push switch is used to start or stop the visual inspection equipment.

[0009] Preferably, the base is also provided with a display screen, which is used to display the voltage and the current passing through the wire during the test.

[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 1 As shown, a B-pillar light-emitting module wiring harness detection device mainly includes a base 1, on which a first fixed platform 2, a second fixed platform 3, and a detection platform 4 are arranged in a linear manner to facilitate the fixing and detection of the wiring harness.

[0016] The mounting platform 2 is located on the rear side of the base 1, and a mounting slot 5 is provided on it. The opening size of the mounting slot 5 matches the wiring terminals of the wire harness being tested, making it easy to insert and fix the wiring terminals. The mounting slot 5 is set at an angle, and the insertion direction of the wiring terminals is angled downward, so that the wiring terminals are not easy to fall out of the mounting slot 5, ensuring connection stability.

[0017] 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.

[0018] 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.

[0019] One end of the wire trough 6 is provided with a wire harness trough 12, where two wires are fixed into a wire harness segment by an insulating sleeve, and the wire harness segment is snapped into the wire harness trough 12. A push switch 13 is provided inside the wire harness trough 12. When the wire harness segment presses on the push switch 13 and the push switch 13 is pressed down, the push switch 13 will start the visual inspection equipment. When the wire harness segment no longer applies downward force to the push switch 13, the push switch 13 will automatically pop up, and the visual inspection equipment will stop operating.

[0020] To further secure the wire, an electromagnetic lock 9 is installed on the upper surface of the fixing platform 2 3, and a fixing plate 10 is also installed on one side of the fixing platform 2 3. One side of the fixing plate 10 is rotatably connected to the fixing platform 2 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, pressing down on the wire and the wire harness segment. Then the electromagnetic lock 9 is activated to lock the fixing plate 10, preventing the wire from shifting or loosening during the testing process, and also ensuring that the wire harness segment can press down the push switch 13.

[0021] 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.

[0022] 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.

[0023] The PCB board in this design is a long and narrow rectangle, with a width equivalent to that of a single LED bead. The detection hole 8 is similar in size. Therefore, to facilitate the placement of the PCB board into the detection hole 8, an inverted trapezoidal guide groove can be provided at the top of the detection hole 8.

[0024] The base 1 is also equipped with a display screen 14, which is 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.

[0025] In addition, an alarm 15 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 15 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 15 will stop.

[0026] 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.

[0027] 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.

[0028] 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.
