Description

Technical Field

[0001] The utility model relates to the field of bending devices, in particular to an electric connector pin bending device. Background Art

[0002] Electrical connectors are important connection devices, often used in electronic product interfaces. Common devices like mobile phones and computers that need to plug into various external devices require connectors for connection. Electrical connectors consist of a housing and pins. The pins are responsible for connecting and transmitting electronic signals, while the housing is responsible for positioning and protecting the pins. Because the pins are relatively small, precise and stable pin processing requires more professional and precise machine design. To meet the needs of different interfaces, the pins need to be bent using a bending device.

[0003] At present, the authorized patent publication number: CN217545202U discloses a bending device for processing electrical connector pins, comprising a workbench, a mounting block is provided on the upper outer surface of the workbench, a hydraulic lifting and bending mechanism for improving bending efficiency is provided on the upper outer surface of the mounting block, the hydraulic lifting and bending mechanism comprises a support plate, a mounting plate is fixedly installed between the inner surfaces of the support plate, a hydraulic pump is provided on the upper outer surface of the mounting plate, a piston rod is provided on the lower outer surface of the mounting plate, and a connecting block is provided on the other end of the piston rod. The bending device for processing electrical connector pins described in the utility model has a simple structure and convenient operation by being provided with a spiral clamping device, which not only improves the convenience of fixing the pins and improves work efficiency, but also improves the stability of the pins during bending, prevents sliding, improves the accuracy of bending, and prevents the pins from bouncing during bending, thereby improving safety.

[0004] In summary, the above-mentioned prior art improves the stability of the pin during fixation, but it cannot adjust the bending length of the pin, resulting in low pin bending precision. In order to solve the above-mentioned problems, we propose an electrical connector pin bending device. Utility Model Content

[0011] With the above technical solution, the guide groove is provided to guide and limit the connecting block, thereby preventing the threaded plate at the bottom of the connecting block from rotating along with the rotation of the adjusting screw.

[0012] The utility model is further configured as follows: a fixing seat fixedly connected to the cylinder is provided at the top of the inner cavity of the bracket, a slider is fixedly connected to the bottom of the fixing seat, and a sliding groove is provided at the bottom of the inner cavity of the bracket to be slidably connected to the slider.

[0016] The utility model is further configured as follows: the surface of the adjusting screw is rotatably connected to the support plate through a bearing, the bottom of the guide groove is also connected to a movable groove, and the threaded plate is located inside the movable groove.

[0017] With the above technical solution, the setting of the bearing is used to limit the rotation of the adjusting screw at a specific position; the setting of the movable groove facilitates the movement of the threaded plate under the drive of the adjusting screw.

[0018] In summary, the present invention has the following beneficial effects:

[0019] This utility model uses a motor to drive an adjusting screw to rotate clockwise or counterclockwise. The adjusting screw can drive a threaded plate to drive several connecting blocks and several limiting blocks to adjust the position within the corresponding pin placement slots. The limiting blocks can thus limit the length of the pins inserted into the pin placement slots, thereby limiting the bending length of the pins. By providing several pin placement slots for placing pins, lowering the pressure plate to cooperate with the support plate to press the pins, and pushing the bending head upward to bend the pins, the device can not only limit the bending length of the pins, but also meet the bending requirements of multiple pins at a time, helping to improve the bending efficiency of the pins.

And by providing several pin placement grooves 9 for placing pins, the pressure plate 2 is lowered to cooperate with the support plate 3 to press the pin, and the cylinder 10 pushes the bending head 11 upward to bend the pin, so that the device can not only limit the bending length of the pin, but also meet the bending work of multiple pins at a time, which helps to improve the bending efficiency of the pin.

[0030] Furthermore, two cylinders three 14 are provided on the top of the pressure plate 2. The surface of the cylinder three 14 is fixedly connected to the interior of the bracket 1, and the output end of the cylinder three 14 is installed with the pressure plate 2. Through the setting of the cylinder three 14, it is used to push the pressure plate 2 down, thereby pressing the pin down to limit the pin.

[0031] Furthermore, the bottom of the needle groove 9 is connected to a guide groove 15, and the interior of the guide groove 15 is slidingly connected to the connecting block 7. Through the setting of the guide groove 15, it is used to guide and limit the connecting block 7 to prevent the threaded plate 6 at the bottom of the connecting block 7 from rotating with the rotation of the adjusting screw 5.
