Description

Technical Field

[0001] This utility model relates to the field of non-standard automated parts inspection technology, and in particular to a connector inspection and positioning structure. Background Technology

[0002] Connector inspection and positioning structures are core auxiliary devices in the post-production and assembly inspection of connectors. They are primarily used to precisely constrain the connector in a preset position during performance (e.g., conductivity, insulation), dimensional (e.g., pin spacing, shape deviation), and appearance (e.g., shell damage, pin deformation) inspections, ensuring that inspection equipment (e.g., probes, vision cameras, sensors) can stably align with the target inspection point. Their core function is to limit the connector's displacement and movement in space, preventing misjudgments, missed detections, or damage to the inspection equipment or connector due to positional deviations.

[0003] However, in actual testing, the following technical problems were found in the existing positioning structure: Firstly, most designs employ "customized fixing fixtures," which can only accommodate connectors of a single size. When the production line needs to switch to different specifications, the entire positioning component must be replaced, which is not only cumbersome but also causes the production line to stop for 10-30 minutes, significantly reducing production efficiency. Furthermore, multiple sets of different fixtures need to be stocked, significantly increasing equipment procurement and storage costs. Secondly, in pursuit of a "tightly fixed positioning" effect, designs often use closed slots or excessively tight clamping blocks. Operators must forcefully pull when picking up or placing connectors, increasing labor intensity, slowing down the testing pace, and easily scratching the connector shell, leading to a higher product damage rate and affecting the pass rate. Thirdly, they lack flexible adaptive adjustment capabilities. During clamping, they cannot automatically adjust the clamping force and position according to the connector size. Either the clamping is too loose, causing connector displacement during testing and affecting testing accuracy, or the clamping is too tight, further aggravating shell damage. At the same time, some structures lack protective designs, with direct metal-to-metal contact with the connector surface, further amplifying the risk of scratches. This makes it difficult to meet the comprehensive requirements of industrial batch testing for efficiency, cost, and product protection.

[0004] In response to this technical problem, this application proposes a connector detection and positioning structure. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing connector positioning structures, which are mostly custom-made fixtures, which are cumbersome to change, have long downtime and high cost, require force to pick up and put down and are easy to scratch, and lack flexible adaptive adjustment. Therefore, a connector detection and positioning structure is proposed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A connector detection and positioning structure includes a mounting base. Each of the four corners of the top of the mounting base is threaded with fixing bolts. A movable plate is connected to the front end of the top of the mounting base via a transmission assembly. The bottom end of the movable plate is slidably connected to the top of the mounting base. Guide rods are slidably connected to both ends of the movable plate. An abutment plate is fixedly connected to the rear end of each guide rod. A spring is provided on the side of the abutment plate and the movable plate adjacent to each other. The spring is fitted onto the outer rear end of the guide rod. A fixed support plate is fixedly connected to the rear end of the top of the mounting base. A connector body is placed on the side of the fixed support plate and the abutment plate adjacent to each other.

[0007] Furthermore, both ends of the rear side of the abutment plate are fixedly connected to a horizontal plate, and the rear end of the horizontal plate is rotatably connected to a rotating roller, the outer wall of the rotating roller abutting against the opposite side of the side clamping plate.

[0008] Furthermore, both ends of the fixed support plate are provided with reserved sliding grooves, and the inner wall of the reserved sliding groove is slidably connected to a side clamping plate. A sliding rod is fixedly connected to the rear end of each side clamping plate on the same side. The sliding rod is connected to the rear side of the fixed support plate through a reset assembly.

[0009] Furthermore, the transmission assembly includes a connecting rod rotatably connected to the middle of the front side of the movable plate, a cam rotatably connected to the front end of the connecting rod, a motor connected to the bottom of the cam, and the motor being installed inside the front end of the mounting base.

[0010] Furthermore, the reset assembly includes a guide support and a slider. The guide support is fixedly connected to the middle rear side of the fixed support plate. A slider is fixedly connected to the side of the guide support. The outer side of the slider is slidably connected to the inner wall of the guide support. A second spring is sleeved on the outer side of each slider rod. The two ends of the second spring abut against the side clamp and the side of the guide support, respectively.

[0011] Furthermore, the opposite side of the side clamp is a beveled surface facing the front end, and the adjacent side of the side clamp abuts against the bottom left and right sides of the connector body.

[0012] Furthermore, a protective gasket is fixedly connected to each adjacent side of the side clamp, and a protective gasket is fixedly connected to the middle of the rear side of the abutment plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the cam driven by the motor and the connecting rod drive the movable plate and the abutment plate to slide back and forth automatically. With the help of the second spring, the side clamping plate is automatically reset. When picking up or putting down, there is no need to manually disassemble or forcefully pull. Only the motor needs to be controlled to quickly release the three-sided clamping, which greatly improves the picking and putting efficiency. At the same time, the protective pad of the side clamping plate and the protective pad of the abutment plate can directly buffer the clamping force and avoid scratching the shell, effectively reducing the damage rate of the connector.

[0014] 2. In this utility model, the oblique surface of the side clamping plate is squeezed by the roller of the abutment plate and combined with the elastic adjustment of the second spring, so that the side clamping plate can slide adaptively along the reserved slide groove. The connector body of different sizes can be stably fixed by the three-sided clamping structure without replacing any components. Attached Figure Description

A connector body 20 is placed on the side of the fixed support plate 9 and the abutment plate 6 that is close to each other. Specifically, this design aims to address the problems of existing positioning structures, which are often designed with closed slots or overly tight clamping blocks for precise positioning. These issues lead to operators having to forcefully pull and tug on connectors, easily scratching the connector housing and resulting in low efficiency. Furthermore, most positioning structures are "custom-made fixing fixtures," requiring the entire positioning assembly to be replaced during model changes, which is time-consuming (e.g., production line downtime of 10-30 minutes) and costly (requiring multiple sets of fixtures). The mounting base 1 has threaded fixing bolts 2 at each of its four corners. These bolts allow the entire positioning structure to be stably installed at the designated position on the production line. A movable plate 5 is connected to the top front end of the mounting base 1 via a transmission assembly. The bottom end of the movable plate 5 is slidably connected to the top of the mounting base 1. Guide rods 7 are slidably connected to both ends of the movable plate 5. An abutment plate 6 is fixedly connected to the rear end of the guide rod 7. A spring 8 is provided on the side of the abutment plate 6 and the movable plate 5. The spring 8 is sleeved on the outer rear end of the guide rod 7. The spring 8 can provide auxiliary elastic force when the abutment plate 6 is reset. A fixed support plate 9 is fixedly connected to the top rear end of the mounting base 1. A connector body 20 is placed on the side of the fixed support plate 9 and the abutment plate 6. Reference Figures 3-5A horizontal plate 18 is fixedly connected to both ends of the rear side of the abutment plate 6. A rotating roller 19 is rotatably connected to the rear end of the horizontal plate 18. The outer wall of the rotating roller 19 abuts against the opposite side of the side clamping plate 11.

The sliding rod 13 is connected to the rear side of the fixed support plate 9 through a reset assembly. The transmission assembly includes a connecting rod 4, which is rotatably connected to the middle of the front side of the movable plate 5. A cam 3 is rotatably connected to the front end of the connecting rod 4. A motor is connected to the bottom of the cam 3. The motor is installed inside the front end of the mounting base 1. The reset assembly The component includes a guide support 12 and a slider 14. The guide support 12 is fixedly connected to the middle rear side of the fixed support plate 9. The slider 14 is fixedly connected to the side of the guide support 12. The outer side of the slider 14 is slidably connected to the inner wall of the guide support 12. The outer side of the slider 13 is fitted with a second spring 15. The two ends of the second spring 15 abut against the side clamp 11 and the side of the guide support 12 respectively. The side of the side clamp 11 is a beveled surface facing the front end. The side of the side clamp 11 abuts against the left and right sides of the bottom end of the connector body 20. The side of the side clamp 11 is fixedly connected with a first protective gasket 16. The middle rear side of the abutment plate 6 is fixedly connected with a second protective gasket 17. Specifically, both ends of the rear side of the abutment plate 6 are fixedly connected to a horizontal plate 18, and the rear end of the horizontal plate 18 is rotatably connected to a rotating roller 19. The outer wall of the rotating roller 19 abuts against the opposite side of the side clamping plate 11. The rotating roller 19 can reduce the friction between itself and the side clamping plate 11 by rotating, ensuring that the side clamping plate 11 slides smoothly. Both ends of the rear side of the fixed support plate 9 are provided with reserved sliding grooves 10. The inner wall of the reserved sliding grooves 10 is slidably connected to the side clamping plate 11. The reserved sliding grooves 10 provide a guiding function for the sliding of the side clamping plate 11. A sliding rod 13 is fixedly connected to the rear side of the face plate 11 on both sides. The sliding rod 13 is connected to the rear side of the fixed support plate 9 through a reset assembly. The transmission assembly includes a connecting rod 4, which is rotatably connected to the middle of the front side of the movable plate 5. A cam 3 is rotatably connected to the front end of the connecting rod 4. A motor is connected to the bottom of the cam 3. The motor is installed inside the front end of the mounting base 1. The motor is the drive source of the entire positioning structure and can realize automated operation. The reset assembly includes a guide support 12 and a slider 14. The guide support 12 is fixedly connected to the middle of the rear side of the fixed support plate 9. A slider 14 is fixedly connected to the side of the guide support 12 on both sides. The outer side of the slider 14 is slidably connected to the inner wall of the guide support 12. The slider 14 provides stable guidance for the sliding of the sliding rod 13. A second spring 15 is sleeved on the outer side of the sliding rod 13. The two ends of the second spring 15 abut against the side plate 11 and the guide support 12 on both sides respectively. The second spring 15 can drive the side plate 11 to reset when it loses external force. The side of the side plate 11 is separated from the side plate 12. The beveled surface facing the front end facilitates the sliding of the side clamping plate 11 to the adjacent side when the roller 19 is pressing. The adjacent side of the side clamping plate 11 abuts against the left and right sides of the bottom end of the connector body 20. A protective gasket 16 is fixedly connected to the adjacent side of the side clamping plate 11, and a protective gasket 27 is fixedly connected to the middle of the rear side of the abutment plate 6. The protective gasket 16 and the protective gasket 27 can prevent the outer shell of the connector body 20 from being scratched during clamping, and at the same time, they can buffer the clamping force and protect the connector body 20. Working principle: When it is necessary to position and fix the connector body 20, the motor installed inside the front end of the mounting base 1 is started. The motor drives the cam 3 to rotate. During the rotation of the cam 3, it drives the connecting rod 4 that is rotatably connected to it. The connecting rod 4 then drives the movable plate 5 that is rotatably connected to slide along the top of the mounting base 1. When the movable plate 5 slides, it drives the guide rods 7 that are slidably connected at both ends to move synchronously. The abutment plate 6 fixed at the rear end of the guide rod 7 slides backward with the guide rod 7. During the backward sliding of the abutment plate 6, the protective pad 17 at the middle of its rear side gradually approaches the connector. The front side of the device body 20 finally abuts against the abutment plate 6. At the same time, the horizontal plates 18 fixed at both ends of the rear side of the abutment plate 6 move backward synchronously with the abutment plate 6. The rotating roller 19 connected to the rear end of the horizontal plate 18 then contacts the oblique surface of the side clamping plate 11 on the opposite side and generates a squeezing force. Under the action of this force, the side clamping plate 11 slides along the reserved sliding grooves 10 at both ends of the rear side of the fixed support plate 9 to the same side. When the side clamping plate 11 slides, it drives the sliding rod 13 fixed on the same side of the rear end to slide along the slider 14 on the inner wall of the guide support 12. At this time, the spring sleeved on the outside of the sliding rod 13... 15 is compressed and stores elastic potential energy. As the side clamping plate 11 slides, the protective pad 16 on the adjacent side gradually approaches the bottom left and right sides of the connector body 20 and abuts against it. Finally, the abutting plate 6 abuts against the front side of the connector body 20 and the two side clamping plates 11 abut against the bottom left and right sides of the connector body 20, forming a stable three-sided clamping and fixing of the connector body 20. When it is necessary to remove or place the connector body 20, the control motor drives the cam 3 to rotate in the opposite direction. The cam 3 pulls the movable plate 5 forward along the top of the mounting base 1 through the connecting rod 4. As the sliding plate 6 slides forward, the movable plate 5 and the guide rod 7 return to their original positions. At this time, the squeezing force of the roller 19 on the oblique surface of the side clamping plate 11 disappears, and the compressed spring 15 releases its elastic potential energy, pushing the side clamping plate 11 to return to the opposite side along the reserved slide groove 10. At the same time, the spring 8 at the outer rear end of the guide rod 7 assists the movable plate 5 and the abutment plate 6 to return to their original positions quickly. The three-sided clamping state of the connector body 20 is released, and the operator can easily pick up and put down the connector body 20 without having to pull it forcefully, effectively avoiding scratching the outer shell of the connector body 20 and significantly improving the picking and putting efficiency.Furthermore, this structure exhibits excellent adaptability to connector bodies 20 of different sizes. When positioning connector bodies 20 of varying sizes, as the abutment plate 6 slides backward, the rotating roller 19, based on the actual dimensions of the connector body 20, presses the beveled surface of the side clamping plate 11, causing it to slide within the reserved groove 10 to a position compatible with the connector body 20's dimensions. Combined with the elastic force of the second spring 15, this ensures stable clamping of connector bodies 20 of different sizes. Unlike existing customized fixing fixtures, there is no need to disassemble and replace the entire positioning assembly, significantly shortening production line changeover time (no downtime of 10-30 minutes) and eliminating the need for multiple sets of positioning fixtures, thus significantly reducing equipment costs and production time. Simultaneously, the protective pads 16 and 17 further enhance the protection of the connector body 20, reducing damage to the connector body 20's shell during clamping, improving the connector inspection pass rate, and enhancing the reliability of the positioning structure.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
