Abstract
Description
Technical Field
[0001] This invention relates to the field of communication cable processing technology, and more specifically, to a simple apparatus and method for manufacturing a 2M connector for coaxial cables. Background Technology
[0002] In telecommunications engineering, the on-site fabrication of 2M coaxial cable connectors is a common and precise task. Traditional fabrication processes usually require operators to use multiple independent tools (such as multiple wire strippers, crimping pliers, soldering irons, etc.) to complete the process in steps, including: stripping the cable sheath, processing the shielding layer, stripping the inner insulation layer, pre-positioning the core wires, crimping the outer conductor, and soldering the inner conductor.
[0003] During the connector fabrication process, operators need to frequently change tools, which can lead to process interruptions and increased time consumption. Furthermore, the processing depth, force, and position of each step are highly dependent on the operator's experience and feel, which can easily cause various quality problems: excessive stripping may damage the wire core, while insufficient stripping can easily lead to poor contact; if the crimping or soldering is not secure, it can also cause signal loss or connection failure.
[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the present invention aims to provide a simple manufacturing device and method for 2M connectors of coaxial cables. This device integrates four core functions: outer sheath removal, insulation layer removal, crimping, and welding. Through mechanical positioning and sequential control, it enables one-time clamping and multi-step completion, thereby significantly reducing operational difficulty, ensuring the stability and reliability of connector manufacturing quality, and improving work efficiency.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A simple manufacturing device for a 2M connector of coaxial cable includes a base plate, on which a wire stripping mechanism, a crimping mechanism and a welding mechanism are provided. The wire stripping mechanism includes a placement frame fixedly connected to the base plate, a limiting roller rotatably connected to the placement frame, a sliding frame slidably connected to the placement frame, a cutting roller rotatably connected to the sliding frame, and a threaded rod connected to the placement frame. The threaded rod is slidably connected to the sliding frame, and a nut is threadedly connected to the threaded rod. A spring is sleeved between the threaded rod and the sliding frame. The base plate is provided with a stripping component for stripping the outer sheath and insulation layer of the sub-wire.
[0007] The present invention is further configured such that: a positioning plate is slidably connected to the placement rack, and the positioning plate has a plurality of holes, the diameter of which is different.
[0008] The present invention is further configured such that: the stripping assembly includes a placement platform fixedly connected to the base plate, two wire strippers fixedly connected to the placement platform, a positioning ring sleeved on the control handle of the wire strippers, two motors fixedly connected to the placement platform, a threaded rod two fixedly connected to the output shaft of the motors, and a connecting plate threadedly connected to the threaded rod two, wherein the connecting plate is fixedly connected to the adjacent positioning ring.
[0009] The present invention is further configured such that the crimping mechanism includes a controller fixedly connected to the base plate and crimping clamps connected to the controller.
[0010] The invention is further configured such that: the welding assembly includes a control console fixedly connected to the base plate, a winding cylinder fixedly connected to the output shaft of the control console, an electric slide rail fixedly connected to the control console, a slider slidably connected to the electric slide rail, a soldering iron tip fixedly connected to the slider, and a placement seat fixedly connected to the control console; solder wire is wound on the winding cylinder; a guide rod is fixedly connected to the control console; the guide rod has a through hole through which the solder wire can pass; and a protective cover is detachably connected to the control console.
[0011] A simplified method for fabricating a 2M connector for coaxial cables: The method includes the following steps: S1, Conductor end treatment: The stripping mechanism removes the outer sheath of the cable to expose the sub-conductor, and then the stripping assembly removes the outer sheath and insulation layer of the sub-conductor to expose the center conductor, and checks whether the required center conductor is scratched; S2, Crimping Connection: The sub-wire is fixedly connected to the 2M connector through a crimping mechanism, and a tensile test is performed; S3, Welding Connection: The center conductor is welded to the 2M connector welding cup using a welding mechanism, and the welding is inspected.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] A simple apparatus and method for manufacturing a 2M connector for coaxial cables, such as... Figures 1-4 As shown, the device includes a base plate 1, on which a wire stripping mechanism, a crimping mechanism, and a welding mechanism are provided. The wire stripping mechanism includes a placement frame 2 fixedly connected to the base plate 1, a limiting roller 3 rotatably connected to the placement frame 2, a sliding frame 4 slidably connected to the placement frame 2, a cutting roller 5 rotatably connected to the sliding frame 4, and a threaded rod 6 threadedly connected to the placement frame 2. The threaded rod 6 is slidably connected to the sliding frame 4, and a nut 7 is threadedly connected to the threaded rod 6. A spring 8 is sleeved between the nut 7 and the sliding frame 4 on the threaded rod 6. The base plate 1 is provided with a stripping assembly for stripping the outer sheath and insulation layer of the sub-wire. A positioning plate 9 is slidably connected to the placement frame 2. The positioning plate 9 has several holes with different diameters.
[0017] like Figures 1-4 As shown, when making a 2M connector, first insert the cable into the corresponding hole of the positioning plate 9, then slide the positioning plate 9 so that the cable can be laid on the limiting roller 3. Then rotate the threaded rod 6 to drive the sliding frame 4 and the cutting roller 5 to approach and abut against the cable laid on the limiting roller 3. Then continue to rotate the threaded rod 6. At this time, the cutting roller 5 will be inserted into the cable due to the obstruction of the cable, and the spring 8 is in a deformed state. Then the cable can be slowly pulled. During the pulling process, the cable will be cut by the cutting roller 5 to expose several sub-wires.
[0018] like Figures 1-2As shown, the wire stripping assembly includes a placement platform 10 fixedly connected to a base plate 1, two wire strippers 11 fixedly connected to the placement platform 10, a positioning ring 12 sleeved on the control handle of the wire stripper 11, two motors 13 fixedly connected to the placement platform 10, a threaded rod 14 fixedly connected to the output shaft of the motor 13, and a connecting plate 15 threadedly connected to the threaded rod 14. The connecting plate 15 is fixedly connected to the adjacent positioning ring 12. When removing the outer sheath of the sub-wire while retaining the insulation layer, the length of the insulation layer to be stripped is first accurately measured and marked according to the technical document requirements. Then, the sub-wire is placed between the jaws of one of the wire strippers 11 (this wire stripper 11 is used to strip the outer sheath of the sub-wire), ensuring that the cutting position is aligned with the stripping edge. Once the jaws of wire stripper 11 are aligned, motor 13 can be started to rotate threaded rod 14, which in turn moves connecting plate 15 downward. At this time, connecting plate 15 will also move positioning ring 12 downward, causing the jaws of wire stripper 11 to move closer together to strip the outer sheath of the sub-wire. After stripping, motor 13 will reverse to reset wire stripper 11. Then, when it is necessary to remove the insulation layer of the sub-wire while retaining the center conductor, another wire stripper 11 can be controlled in the same way to remove the insulation layer. After the removal is completed, check whether the insulation layer cut is clean and neat, and ensure that the center conductor of the sub-wire is free of broken wires, scratches, and twists, and that the length of the center conductor of the sub-wire meets the requirements.
[0019] like Figures 1-2 As shown, the crimping mechanism includes a controller 16 fixedly connected to the base plate 1 and crimping pliers 17 connected to the controller 16. When crimping the 2M connector to the sub-line, first carefully fold or straighten the exposed shielding layer (foil layer) backward to evenly cover the outer sheath, avoiding excessive pulling that could cause broken wires or sparse areas. Then, use sharp scissors to neatly trim the shielding layer along the edge of the outer sheath, ensuring that the end of the shielding layer is flat and free of excessively long loose wires. Afterward, install the shielding protective layer (first, put a section of metal sleeve on the shielding layer and pull it tight, then reliably tie and fix it at both ends of the sleeve with thin copper wire or cable ties to ensure that it is secure to the outer sheath). (After ensuring good contact of the shielding layer, a layer of ordinary heat shrink tubing is placed over the metal sleeve for protection and insulation.) Then, crimping can be performed. The stripped insulation layer of the sub-wire is fully inserted into the crimping sleeve of the 2M connector. At this time, the sub-wire conductor will be inserted into the solder cup of the 2M connector. Then, the crimping sleeve of the 2M connector is placed in the jaws of the crimping pliers 17. Then, the crimping pliers 17 are controlled by the controller 16 to perform crimping. After that, the crimping is checked to ensure that the crimped part is symmetrical, without cracks, and without excessive deformation. Then, the 2M connector is gripped and the sub-wire is gently pulled to ensure that the sub-wire connection is secure.
[0020] like Figures 1-4As shown, the welding assembly includes a control console 18 fixedly connected to the base plate 1, a winding drum 19 fixedly connected to the output shaft of the control console 18, an electric slide rail 20 fixedly connected to the control console 18, a slider 21 slidably connected to the electric slide rail 20, a soldering iron tip 22 fixedly connected to the slider 21, and a placement seat 23 fixedly connected to the control console 18 (which can restrict the front and rear positions of the 2M connector). Solder wire 24 is wound on the winding drum 19. A guide rod 25 is fixedly connected to the control console 18, and the guide rod 25 has a through hole for the solder wire 24 to pass through. A protective cover 26 is detachably connected to the control console 18 (for easy replacement of the winding drum 19). During welding, the soldering iron tip 22 is first turned on for preheating. Then, the 2M connector can be placed on the placement seat 23, ensuring that the front of the 2M connector is facing upwards. Then, the output shaft of the control console 18 can be driven to rotate, at which time the winding drum 19 will also rotate, winding the winding drum 19... Solder wire 24 on the soldering iron tip 22 is guided by guide rod 25 to the space between the soldering iron tip 22 and the 2M connector. Simultaneously, the electric slide rail 20 starts, moving the slider 21 and soldering iron tip 22 closer to the 2M connector. When the soldering iron tip 22 contacts the solder wire 24, it melts and carries the molten solder wire 24 into the solder cup of the 2M connector, wetting the inner wall of the solder cup and forming a thin, uniform solder layer. Then, the soldering iron tip 22 contacts the solder cup of the 2M connector and heats it for soldering. The solder inside the 2M connector solder cup is completely melted. At this point, the molten solder will flow naturally into and fill the solder cup due to capillary action. Then, the electric slide rail 20 will move the soldering iron tip 22 away from the 2M connector. When the solder has completely cooled and solidified, the soldering is considered complete. Then, the soldering inspection can be performed. When inspecting, ensure that the solder completely wets the center conductor and the inner wall of the solder cup, and ensure that there are no cracks, no pores, no spikes, no cold solder joints, no solder splatter, and no excessive flux residue.
[0021] Working principle: When making a 2M connector, first insert the cable into the corresponding hole of the positioning plate 9, then slide the positioning plate 9 so that the cable can be laid on the limiting roller 3. Then rotate the threaded rod 6 to drive the sliding frame 4 and the cutting roller 5 to approach and abut against the cable laid on the limiting roller 3. Then continue to rotate the threaded rod 6. At this time, the cutting roller 5 will be inserted into the cable due to the obstruction of the cable, and the spring 8 is in a deformed state. Then the cable can be slowly pulled. During the pulling process, the cable will be cut by the cutting roller 5 to expose several sub-wires.
[0022] When removing the outer sheath of the sub-wire while retaining the insulation layer, first accurately measure and mark the length of the insulation layer to be stripped according to the technical document requirements. Then, place the sub-wire between the jaws of one wire stripper 11, aligning the cutting position with the cutting position of the jaws of the wire stripper 11. Then, start the motor 13 to drive the threaded rod 14 to rotate, which in turn drives the connecting plate 15 to move downward. At this time, the connecting plate 15 will also drive the positioning ring 12 to move downward, causing the jaws of the wire stripper 11 to move closer together to strip the outer sheath of the sub-wire. After the stripping is completed, the motor 13 will reverse to reset the wire stripper 11. Then, when it is necessary to remove the insulation layer of the sub-wire while retaining the center conductor of the sub-wire, the other wire stripper 11 can be controlled in the same way to remove the insulation layer of the sub-wire. After the removal is completed, check whether the insulation layer cut is clean and neat, and ensure that the center conductor of the sub-wire is free of broken wires, scratches, twists, and that the length of the center conductor of the sub-wire meets the requirements.
[0023] When crimping a 2M connector to a sub-line, carefully fold or straighten the exposed shielding layer (foil) to evenly cover the outer sheath, avoiding excessive stretching that could cause broken wires or sparse areas. Then, use sharp scissors to neatly trim the shielding layer along the edge of the outer sheath, ensuring the end of the shielding layer is flat and free of excessively long loose wires. Next, install the protective shielding layer (first, slip a section of metal tubing over the shielding layer and tighten it, securing it securely at both ends with thin copper wire or cable ties to ensure good contact with the shielding layer. Then, add another layer over the metal tubing). (Use ordinary heat shrink tubing for protection and insulation), then crimping can be performed. The stripped insulation layer of the sub-wire is fully inserted into the crimping sleeve of the 2M connector. At this time, the sub-wire conductor will be inserted into the solder cup of the 2M connector. Then, place the crimping sleeve of the 2M connector into the jaws of the crimping pliers 17, and then use the controller 16 to control the crimping pliers 17 to perform crimping. After that, perform a crimping inspection to ensure that the crimped part is symmetrical, without cracks, and without excessive deformation. Then, grasp the 2M connector and gently pull the sub-wire to ensure that the sub-wire connection is secure.
[0024] During soldering, first preheat the soldering iron tip 22, then place the 2M connector on the placement base 23, ensuring the 2M connector face up. Then, drive the output shaft of the control console 18 to rotate, which will also rotate the winding drum 19. The solder wire 24 on the winding drum 19 is guided by the guide rod 25 to the space between the soldering iron tip 22 and the 2M connector. Simultaneously, the electric slide rail 20 will start, moving the slider 21 and the soldering iron tip 22 closer to the 2M connector. When the soldering iron tip 22 touches the solder... When the solder wire 24 comes into contact, it melts and carries the molten solder wire 24 into the 2M connector solder cup, wetting the inner wall of the solder cup and forming a thin and uniform solder layer. Then the soldering iron tip 22 will come into contact with the 2M connector solder cup and heat the solder cup until the solder inside the 2M connector solder cup is completely melted. At this time, the molten solder will flow naturally into and fill the solder cup due to capillary action. Then the electric slide rail 20 will move the soldering iron tip 22 away from the 2M connector. When the solder has completely cooled and solidified, the soldering is considered to be completed, and then the soldering inspection can be performed.
