Description

Technical Field

[0001] This utility model relates to the field of positioning and detection technology, and in particular to a terminal positioning and detection device for preventing terminal misalignment. Background Technology

[0002] In the field of electrical connector and terminal testing technology, accurate terminal positioning and stability are key factors in ensuring electrical connection quality and equipment performance. Chinese Utility Model Patent, authorized publication number "CN218567584U", discloses a terminal positioning and testing device to prevent terminal misalignment. This invention adds an anti-misalignment component to the testing device. During the testing phase, when the connector terminal is misaligned, the terminal cannot contact the testing probe through the terminal inspection hole, resulting in test failure. This ensures that 100% of wire harnesses with misaligned terminals fail the test. Thus, during terminal testing, it is possible to directly detect whether the terminal has internal deformation or other misalignment issues. Simultaneously, it eliminates the need for inspection tools and visual inspection, reducing an inspection station and saving inspection time. The test results can be automatically recorded in the production management system by the testing instrument.

[0003] While the above-mentioned technical solution can detect terminal misalignment during use, it can only manually pick up and place one terminal at a time, which wastes a lot of time and leads to discontinuous terminal detection. This discontinuous detection method is inefficient and cannot meet the needs of modern large-scale, high-efficiency production. The detection speed and continuity of the detection device seriously restrict the improvement of production efficiency. Therefore, we propose a terminal positioning detection device to prevent terminal misalignment. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a terminal positioning detection device for preventing terminal misalignment, comprising:

[0028] Terminal testing station 1, with a fixed frame 2 fixedly connected to the top of terminal testing station 1, the fixed frame 2 having a "C" shaped structure;

[0029] Terminal detection structure, located on terminal detection stage 1;

[0030] The terminal detection structure includes a rotating platform 3, a detection positioning column 5, and an electric push rod 6. The rotating platform 3 is rotatably connected to the top of the terminal detection platform 1. The top of the rotating platform 3 has multiple slots 4. The electric push rod 6 is fixedly installed on the top of the fixed frame 2. The telescopic end of the electric push rod 6 slides into the interior of the fixed frame 2 and is fixedly connected to the detection positioning column 5. The interior of the detection positioning column 5 has a sliding groove 19. The inner wall of the sliding groove 19 has two moving grooves 14. The bottom of the detection positioning column 5 has a through groove 18 that communicates with the interior of the sliding groove 19. The inner top wall of the sliding groove 19 is fixedly installed with a fixing patch 13. The sliding groove 19 and the two moving grooves 14 are slidably connected with moving patches 15. The interior of each of the two moving grooves 14 is fixedly connected with a limit rod 17. The two ends of the moving patch 15 are slidably sleeved on the outer surface of the corresponding limit rod 17. The outer surface of each of the two limit rods 17 is sleeved with a spring 16.

[0031] A rotating shaft 9 is fixedly connected to the bottom of the rotating platform 3. The bottom end of the rotating shaft 9 rotates through the terminal detection platform 1. A main gear 8 is fixedly sleeved on the outer surface of the rotating shaft 9. A mounting bracket 10 is fixedly connected to one side of the terminal detection platform 1. A drive motor 11 is fixedly installed inside the mounting bracket 10. A special-shaped gear 12 is fixedly connected to the output end of the drive motor 11. The special-shaped gear 12 meshes with the main gear 8.

[0032] The bottom ends of both springs 16 are fixedly connected to the top of the movable patch 15, and the top ends of both springs 16 are fixedly connected to the inner top wall of the corresponding movable groove 14.

[0033] A prompter 7 is fixedly installed on the top of the mounting bracket 2. The prompter 7 is connected to the fixed patch 13 and the movable patch 15 respectively via connecting wires. The inner wall of the sliding groove 19 is provided with a wire hole and a wire groove, and the two connecting wires are located in the corresponding wire hole and wire groove respectively.

[0034] Furthermore, when using the device, the user inserts the terminal into the slot 4 and starts the drive motor 11 by connecting an external power source. The drive motor 11 drives the shaped gear 12 to rotate. The rotation of the shaped gear 12 drives the main gear 8 meshing with it to rotate. Since the shaped gear 12 is an shaped gear, its teeth will only cause the main gear 8 to rotate at a certain angle, so that the main gear 8 can drive the rotating table 3 to rotate through the rotating shaft 9. This makes it easier to rotate the slot 4 on the rotating table 3 to the bottom of the detection positioning post 5, so that the terminals to be detected next to the detection positioning post 5 will rotate to the bottom of it one by one.

[0035] Furthermore, when using this device, the electric push rod 6 is activated by connecting an external power source. The electric push rod 6 will drive the detection positioning post 5 to move downward. The downward movement of the detection positioning post 5 will cause the top of the terminal to be inserted into the sliding groove 19 through the through groove 18, so that the top of the terminal presses against the movable patch 15. When the movable patch 15 is pressed, it will compress the two springs 16 under the guidance of the two limit rods 17. Thus, the movable patch 15 will come into contact with the fixed patch 13 under the pressure of the terminal. The parts of the fixed patch 13 and the movable patch 15 that come into contact are both iron sheets. After the movable patch 15 and the fixed patch 13 come into contact, the connecting wires on them will cause the current to flow, which will facilitate the display of a green light on the detection light of the indicator 7. When the terminal is crooked, it will not be inserted into the detection positioning post 5, and thus the indicator 7 will not be able to display a green light. After one test, the movable patch 15 will be reset under the action of the two springs 16.

[0036] With the cooperation of the rotating table 3, main gear 8, special gear 12, fixed patch 13 and movable patch 15, the rotating table 3 can drive the terminal to rotate at equal intervals. Thus, when the fixed patch 13 and the movable patch 15 are in contact and energized, the normal terminal can display the correct light color, while the skewed terminal cannot enter the sliding groove 19 to squeeze the movable patch 15, reducing the time when the terminal is picked up and put down, thereby facilitating continuous detection of the terminal and further improving the efficiency of terminal detection.
