Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, and in particular to a low-voltage wire harness testing device. Background Technology

[0002] In today's manufacturing environment, low-voltage wire harnesses are a critical component of many devices, making their quality inspection essential. Traditional low-voltage wire harness testing methods primarily rely on manual point-by-point measurements using a multimeter. While this approach was effective in past production environments, with the continuous development of industrial production and the expansion of production scale, the demands for efficiency and accuracy in wire harness testing are increasing. Against this backdrop, the shortcomings of traditional testing methods have become increasingly apparent, urgently requiring a more efficient and accurate low-voltage wire harness testing device to meet the testing needs of modern industrial production.

[0003] Traditional methods suffer from poor probe adaptability, requiring frequent fixture changes for different specifications and types of wire harnesses. This not only increases operational complexity but also significantly reduces testing efficiency, wasting considerable manpower and time. Secondly, they cannot simultaneously perform composite tests such as continuity, insulation, and withstand voltage. In actual testing, different tests are often performed multiple times, extending the testing cycle and potentially leading to omissions or errors, making it impossible to comprehensively and accurately assess the quality of the wire harness. Furthermore, traditional testing methods lack intelligent error compensation, making it difficult to maintain stable testing accuracy under complex environmental interference, easily leading to misjudgments or inaccurate results, posing potential risks to product quality and production safety.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-5 This utility model provides a low-voltage wire harness testing device, including a base 1, a testing device body 2, and a feeding mechanism. The feeding mechanism includes a driving component, a moving component, a moving frame 3, a supporting component, two supporting plates 4, and a placement plate 5. The testing device body 2 is mounted on the base 1, the driving component is installed inside the base 1, the moving component is mounted on the driving component, the moving frame 3 is slidably connected to the base 1 and connected to the moving component, the supporting component is mounted on the moving frame 3, both supporting plates 4 are mounted on the supporting component, and the placement plate 5 is fixedly connected to the moving frame 3 and located on the moving frame 3.

[0020] In this embodiment, the base 1 provides installation conditions for the detection device body 2 and the feeding mechanism. When low-voltage wire harnesses need to be tested, the wire harnesses to be tested are placed sequentially on the placement plate 5. The holding component is activated, and the holding component drives the two holding plates 4 to move closer to the placement plate 5 until the two holding plates 4 are released from the wire harness and the two ends of the wire harness are held and fixed. Then, the driving component is activated, and the driving component drives the moving component to move on the base 1. The moving component drives the multiple wire harnesses on the moving frame 3 to move closer to the detection device body 2 until the detection ends of the multiple wire harnesses are inserted into the corresponding detection ports of the detection device body 2. Then, the detection device body 2 can be activated to test the multiple wire harnesses, thereby solving the problem that the existing low-voltage wire harness testing method can only test one wire at a time with low efficiency.

[0021] Furthermore, the drive assembly includes a motor 6, a bidirectional screw 7, and two movable cylinders 8. The motor 6 is fixedly connected to the base 1 and located inside the base 1. The bidirectional screw 7 is fixedly connected to the output end of the motor 6 and rotatably connected to the base 1. The two movable cylinders 8 are respectively threadedly connected to the bidirectional screw 7 and are respectively located on the bidirectional screw 7.

[0022] In this embodiment, the operation of the motor 6 can drive the bidirectional screw 7 to rotate. The rotation of the bidirectional screw 7 can cause the two moving cylinders 8 to move closer to each other or further away from each other. The movement of the two moving cylinders 8 can cause the two transmission rods 11 to rotate.

[0023] Furthermore, the drive assembly also includes a guide rail 9 and two guide blocks 10. The guide rail 9 is fixedly connected to the base 1 and located inside the base 1. The two guide blocks 10 are slidably connected to the guide rail 9 and fixedly connected to the two movable cylinders 8 respectively.

[0024] In this embodiment, the guide rail 9 provides installation conditions for the two guide blocks 10. The two guide blocks 10 can guide and limit the two moving cylinders 8, thereby improving the stability of the two moving cylinders 8 when they move.

[0025] Furthermore, the moving assembly includes two transmission rods 11, a top rod 12, and a connecting rod 13. The two transmission rods 11 are rotatably connected to the two moving cylinders 8 respectively and are located on the two moving cylinders 8 respectively. The top rod 12 is rotatably connected to the two transmission rods 11 and is located between the two transmission rods 11. The connecting rod 13 is fixedly connected to the top rod 12 and fixedly connected to the moving frame 3, and is located between the moving frame 3 and the top rod 12.

[0026] In this embodiment, when the two moving cylinders 8 move, they drive the two transmission rods 11 to move. When the angle between the two moving cylinders 8 and the two transmission rods 11 decreases, the two transmission rods 11 drive the top rod 12 to move closer to the bidirectional screw 7, thereby driving the moving frame 3 on the connecting rod 13 to move away from the detection device body 2. When the angle between the two moving cylinders 8 and the two transmission rods 11 increases, the two transmission rods 11 drive the top rod 12 to move away from the bidirectional screw 7, thereby driving the moving frame 3 on the connecting rod 13 to move closer to the detection device body 2.

[0027] Furthermore, the supporting assembly includes an electric push rod 14, a mounting plate 15, and two guide rods 16. The electric push rod 14 is fixedly connected to the movable frame 3 and located on the movable frame 3. The mounting plate 15 is fixedly connected to the output end of the electric push rod 14 and slidably connected to the movable frame 3, and is also fixedly connected to the two supporting plates 4. The two guide rods 16 are respectively fixedly connected to the mounting plate 15 and slidably connected to the movable frame 3, and both penetrate the movable frame 3.

[0028] In this embodiment, the electric actuator 14 can drive the mounting plate 15 to move. The movement of the mounting plate 15 can cause the two abutment plates 4 to move towards the side closer to the placement plate 5 or away from the placement plate 5. The two guide rods 16 can guide and limit the mounting plate 15, thereby improving the stability of the mounting plate 15 during movement.
