Description

Technical Field

[0001] This utility model relates to the field of connector processing technology, and in particular to a connector pin bending device. Background Technology

[0002] In the field of connector manufacturing, pin bending is a crucial process to ensure the compatibility of subsequent connector assembly. It requires precisely bending the upper and lower rows of pins at the connector end to a specific angle. However, existing connector bending devices have significant technical shortcomings: First, low processing efficiency, with most devices only capable of bending a single connector at a time, making it impossible to process multiple connectors simultaneously and failing to meet the demands of mass production; second, poor versatility, lacking flexible adaptability structures for different connector specifications, requiring overall equipment adjustments when changing processing models, resulting in cumbersome operations and high adaptation costs; and third, insufficient positioning stability, lacking a reliable positioning structure, causing connectors to easily shift vertically or deviate in the bending direction during bending, leading to inconsistent pin bending angles and misaligned bending positions, severely impacting connector processing accuracy and product yield.

[0003] Therefore, those skilled in the art have provided a connector pin bending device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connector pin bending device.

A positioning bracket is connected to the carrier via a detachable structure. One end of the positioning bracket has a slot that matches the contour of the connector to be processed, and the connector to be processed is inserted and positioned through the slot. A row of pins to be bent is provided on the upper and lower sides of the end of the connector to be processed. Support plates are symmetrically fixedly connected to the top two sides of the base. Rotating shafts are rotatably installed on the opposite sides of the two support plates. A swing arm is fixedly connected to the adjacent end of the two rotating shafts. A crossbar is fixedly connected between the two swing arms. Bending plates are fixedly connected to the top two sides of the crossbar by fastening screws. The free end of the bending plate faces the bottom of the single row of pins of the corresponding connector to be processed, and the top of the bending plate is in contact with the bottom surface of the pin to be bent. One of the rotating shafts has a rotating handle fixedly connected to one end extending outside the support plate.

[0006] Preferably, a rotating disk is fixedly sleeved on the outer side of each of the two rotating shafts, and the two rotating disks are respectively attached to the opposite sides of the two support plates; The outer wall of the rotating disk has a notch, and a spring fixing column is fixedly connected to the top edge of the outer side of the support plate. A tension spring is installed between the spring fixing column and the side wall of the notch away from the center of the rotation axis.

[0007] Preferably, a stop post is fixedly connected to the outer side of the support plate and the area inside the notch.

[0008] Preferably, the inner wall of the U-shaped slide block is provided with sliding grooves on both the left and right sides, and the left and right ends of the bearing slide block are fixedly connected with sliders, and the two sliders slide in cooperation with the two sliding grooves respectively.

[0009] Preferably, an L-shaped block is fixedly connected to one end of the carrier facing the bending plate. The L-shaped block includes an integrally formed vertical section and a horizontal section, with the horizontal section located below the vertical section. A limiting member is fixedly connected to the side of the L-shaped block, and the limiting member includes an upper limiting rod and a lower limiting rod. An upper limit rod is horizontally fixedly connected to the side of the vertical section away from the horizontal section, and a lower limit rod is horizontally fixedly connected to the side of the horizontal section away from the vertical section. The upper limit rod is located above the upper row of pins of the connector to be processed, and the lower limit rod is located above the lower row of pins of the connector to be processed. A stop bar is horizontally fixed to the side of the vertical section near the connector to be processed, and the stop bar is in close contact with the end face of the connector to be processed.

[0010] Preferably, a folded winding rod is fixedly connected to the side of the L-shaped block away from the limiting member, and a T-shaped guide block is fixedly connected to the free end of the folded winding rod after it passes over the top of the carrier. A T-shaped guide groove adapted to the T-shaped guide block is opened on the side of the carrier away from the connector to be processed, and the T-shaped guide block is slidably connected in the T-shaped guide groove.

[0011] Preferably, the side of the carrier is provided with a mounting groove that matches the contour of the positioning card seat, and the positioning card seat is slidably inserted into the mounting groove; Positioning blocks are fixedly connected to both sides of the positioning card holder, and positioning slots that are adapted to the positioning blocks are opened on both sides of the mounting slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By using two carriers with horizontal and vertical bidirectional staggered settings, the upper row of pins of the unbent connector on the left and the lower row of pins of the connector with the completed upper row bend on the right can be processed simultaneously, significantly improving processing efficiency compared to traditional devices that bend a single connector at a time. The positioning bracket and carrier are detachable and adaptable, allowing for quick replacement to match different connector specifications, effectively solving the problem of poor versatility. The positioning bracket slot restricts the connector's vertical movement, the stop rod prevents it from shifting in the bending direction, and the stop post limits the bending angle. The combination of multiple positioning and limiting structures avoids connector shifting and pin bending angle deviation, ensuring processing accuracy. At the same time, the tension spring can drive the bent parts to automatically reset, eliminating the need for manual repositioning and reducing operational intensity. Overall, it balances high efficiency, versatility, and precision, meeting the needs of mass production. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-6 A connector pin bending device includes a base 1, a U-shaped slide 2 with an upward opening fixed to the top of the base 1, a carrying slide 3 slidably connected to the inner side of the U-shaped slide 2, a carrier 4 fixedly connected to both sides of the top of the carrying slide 3, a positioning card 5 connected to the carrier 4 by a detachable structure, a slot adapted to the contour of the connector 24 to be processed at one end of the positioning card 5, and the connector 24 to be processed is positioned by inserting into the slot, and a row of pins to be bent is provided on the upper and lower sides of the end of the connector 24 to be processed. Support plates 6 are symmetrically fixedly connected to the top two sides of the base 1. Rotating shafts 7 are rotatably installed on the opposite sides of the two support plates 6. A swing arm 8 is fixedly connected to the adjacent end of the two rotating shafts 7. A crossbar 9 is fixedly connected between the two swing arms 8. A bending plate 10 is fixedly connected to both sides of the top of the crossbar 9 by fastening screws. The free end of the bending plate 10 faces the bottom of the single row of pins of the corresponding connector 24 to be processed, and the top of the bending plate 10 is in contact with the bottom surface of the pin to be bent. One of the rotating shafts 7 extends outward from the support plate 6 and is fixedly connected to a rotating handle 11.

[0019] Using the above technical solution, the base 1 provides a stable support foundation, and the U-shaped slide 2 cooperates with the bearing slide 3 to adjust the position of the connector to be processed, ensuring that the connector can be accurately approached by the bending mechanism. The carrier 4 and the positioning card 5 form a detachable positioning structure, which can not only achieve a stable insertion of the connector 24 to be processed through the slot, but also facilitate the replacement of the appropriate positioning card according to different connector specifications, improving the versatility of the device. When the rotating shaft 7 rotates, it will synchronously drive the swing arms 8 fixed at both ends to rotate around the axis of the rotating shaft, and the crossbar 9 connects the two swing arms, thereby driving the bending plate 10 at the top of the crossbar to rotate synchronously with the swing arms. Since the free end of the bending plate is pre-fitted to the bottom surface of the pin to be bent on the connector 24, its rotation process is equivalent to forming a bending fulcrum around its own free end. The force applied by the rotation causes the pin to be bent along the fulcrum, and finally the pin can be accurately bent to about ninety degrees, which meets the conventional assembly angle requirements of the connector pin. Moreover, the overall transmission path is direct, the bending action is stable and controllable, and the consistency of the pin bending angle is ensured.

[0020] A rotating disk 12 is fixedly sleeved on the outer side of each of the two rotating shafts 7, and the two rotating disks 12 are respectively attached to the opposite sides of the two support plates 6. The outer wall of the rotating disk 12 has a notch 13. A spring fixing post 14 is fixedly connected to the top edge of the outer side of the support plate 6. A tension spring 15 is installed between the spring fixing post 14 and the side wall of the notch 13 away from the center of the rotating shaft 7.

[0021] By adopting the above technical solution, when the rotating handle drives the bending plate to complete the pin bending, the rebound force of the tension spring can drive the rotating disk to rotate in the opposite direction when the rotating handle is released. Then, through the rotating shaft, swing arm and other transmission components, the bending plate is automatically reset to the initial position. There is no need for manual reset, which reduces the labor intensity of the operator and avoids subsequent feeding or bending operations being blocked due to forgetting to reset. This significantly improves the ease of operation and processing efficiency of the device.

[0022] A stop post 16 is fixedly connected to the outer side of the support plate 6 and the inner area of ​​the notch 13.

[0023] By adopting the above technical solution, by setting the stop post 16 on the outer side of the support plate 6 and the inner side of the notch 13, the rotation range of the rotating disk can be physically limited during the rotation of the rotating disk with the rotating shaft. When the rotating disk rotates to the point where the side wall of the notch abuts against the stop post, the rotating shaft can no longer rotate, thereby limiting the maximum bending angle of the bending plate 10. This effectively avoids the problem of over-bending of the pins or inconsistent bending angles caused by excessive force when the operator manually rotates the handle, ensuring the uniformity of the pin bending accuracy of each batch of connectors and reducing the defect rate.

[0024] Slide grooves 17 are provided on both the left and right sides of the inner wall of the U-shaped slide block 2. Slide blocks 18 are fixedly connected to both the left and right ends of the bearing slide plate 3. The two slide blocks 18 slide in cooperation with the two slide grooves 17 respectively.

[0025] Using the above technical solution, the sliding groove 17 on the inner wall of the U-shaped slide block 2 and the sliders 18 at both ends of the bearing slide plate 3 slide together, which can provide precise guidance for the bearing slide plate and prevent it from deviating during sliding; and the end of the groove facing the bending plate 10 is a closed end. When the slider slides to the closed end, the bearing slide plate drives the connector 24 to be processed to reach the bending working position. No additional calibration is required, and the connector and the bending plate are quickly and accurately aligned, improving the feeding efficiency and bending accuracy.

[0026] An L-shaped block 19 is fixedly connected to one end of the carrier 4 facing the bending plate 10. The L-shaped block 19 includes an integrally formed vertical section and a horizontal section, with the horizontal section located below the vertical section. A limiting member 20 is fixedly connected to the side of the L-shaped block 19. The limiting member includes an upper limiting rod and a lower limiting rod. An upper limit rod is horizontally fixedly connected to the side of the vertical section away from the horizontal section, and a lower limit rod is horizontally fixedly connected to the side of the horizontal section away from the vertical section. The upper limit rod is located above the upper row of pins of the connector 24 to be processed, and the lower limit rod is located above the lower row of pins of the connector 24 to be processed. A stop rod 21 is horizontally fixedly connected to the side of the vertical section near the connector 24 to be processed, and the stop rod 21 is tightly fitted to the end face of the connector 24 to be processed.

[0027] Using the above technical solution, the L-shaped block 19 fixed on the carrier 4 is divided into a vertical section and a horizontal section. The lower limit rod and the upper limit rod connected to the horizontal section and the vertical section respectively can cover the lower row and the upper row of pins of the connector 24 to be processed. When the bending plate bends the pins, it effectively restricts the pins from tilting upwards and avoids deformation or positional displacement of the pins during the bending process. Meanwhile, combined with the slot design of the positioning bracket 5 shown in the figure, the connector to be processed is inserted and positioned from one end of the slot. The slot contour is adapted to the connector, which can physically limit the connector from the top and bottom, effectively restricting the connector from moving in the vertical direction. The abutment 21 of the vertical section of the L-shaped block 19 is tightly fitted with the end face of the connector 24 to be processed, which can directly prevent the connector from shifting and sliding towards the bending plate 10 during the bending process, avoiding the connector from moving due to force, and ensuring the alignment accuracy of the pins and the bending plate.

[0028] A folded winding rod 22 is fixedly connected to the side of the L-shaped block 19 away from the limiting member 20. After the free end of the folded winding rod 22 passes over the top of the carrier 4, a T-shaped guide block 23 is fixedly connected. A T-shaped guide groove adapted to the T-shaped guide block 23 is opened on the side of the carrier 4 away from the connector 24 to be processed. The T-shaped guide block 23 is slidably connected in the T-shaped guide groove.

[0029] Using the above technical solution, the folded winding rod 22 bypasses the interference area above the carrier 4 through a bending design. The T-shaped guide block 23 connected to it slides in cooperation with the T-shaped guide groove on the rear side of the carrier (not shown in the figure), which provides horizontal guidance for the L-shaped block 19 and prevents the slider from falling out because the two ends of the guide groove are closed. After the connector 24 to be processed is installed, the sliding L-shaped block can drive the upper limit rod and the lower limit rod to move precisely to the position to be limited, ensuring bending stability. After bending is completed, the L-shaped block is slid in the opposite direction, which allows the stop rod 21 and the limit rod to be separated from the connector area, which is convenient for quick and easy picking and putting away of the connector, taking into account both adjustment accuracy and operation convenience. At the same time, the folded winding rod 22 and the T-shaped guide block 23 can be designed to be detachably connected, which makes it easy to replace the appropriate limit rod 20 according to different connectors.

[0030] The side of the carrier 4 is provided with an installation groove that matches the contour of the positioning card 5, and the positioning card 5 is slidably inserted into the installation groove. Positioning blocks 51 are fixedly connected to both sides of the positioning base 5, and positioning grooves that are adapted to the positioning blocks 51 are opened on both sides of the mounting groove. Multiple fastening screws are installed through the top of the carrier 4, and the bottom of the fastening screws are threadedly connected to the threaded hole at the top of the positioning block 51.

[0031] Using the above technical solution, the mounting slot of the carrier 4 and the positioning card 5 are fitted and inserted, and the positioning block 51 and the positioning slot are limited. The positioning block is then locked by the fastening screw. This allows for quick disassembly and assembly of the positioning card to adapt to connectors 24 of different specifications to be processed, and also firmly fixes the positioning card to prevent the card from loosening during bending and causing the connector to shift. This balances versatility and positioning stability.

[0032] The two carriers 4 are staggered in both the horizontal and vertical directions, with the free end of one bending plate 10 facing below the upper row of pins of the left connector 24 to be processed, and the free end of the other bending plate 10 facing below the lower row of pins of the right connector 24 to be processed.

[0033] Using the above technical solution, the two carriers 4 are staggered horizontally and vertically to precisely adapt to the step-by-step bending requirements of the connector pins: the vertical stagger ensures that the upper and lower rows of pins of the connector 24 to be processed on the two carriers are at different vertical heights, ensuring that the bending plates 10 on both sides can respectively correspond to the upper row of pins of the unbent connector on the left and the lower row of pins of the connector with the upper row of pins already bent on the right, providing independent bending space; the horizontal stagger ensures that the bending positions of the subsequent upper and lower rows of pins of the same connector are staggered, avoiding overlap after bending, and ensuring that the two rows of pins are finally in a parallel state to meet assembly requirements. In actual use, the unbent connector is placed on the left carrier and the connector with the upper row of pins already bent is placed on the right carrier. The bending plates on both sides work simultaneously to achieve simultaneous operation of "upper row bending of unbent connectors + lower row bending of bent connectors", effectively improving processing efficiency.

[0034] Working principle: Place the connector with two rows of unbent pins into the left positioning slot 5, and the connector with the upper row of pins bent into the right positioning slot 5. Push the bearing slide plate 3 to make the slider 18 slide along the slide groove 17 of the U-shaped slide block 2 to the closed end. At this time, the connector reaches the bending working position. Slide the L-shaped block 19, and through the cooperation of the bending rod 22 and the T-shaped guide block 23, drive the limiting rod and the stop rod 21 to position the connector. Rotate the rotating handle 11, and the rotating shaft 7 drives the swing arm 8, the crossbar 9 and the bending plate 10 to rotate. The bending plates on both sides bend the upper row of pins of the left connector and the lower row of pins of the right connector by about 90 degrees. After bending, release the rotating handle 11, and the tension spring 15 drives the parts to reset. Slide the L-shaped block 19 in the opposite direction to take out the connector and complete the bending operation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
