[0002] Network transformers, also known as Ethernet transformers or LAN transformers, are key components used in Ethernet interfaces. They are mainly used for signal isolation, impedance matching, and electromagnetic compatibility (EMC) protection. A network transformer mainly consists of a transformer housing, coils, and pins. The coils are formed by winding high-conductivity leads (enameled wire) onto a magnetic ring, which is the core component inside the network transformer. During the production process of network transformers, winding equipment is often used to wind the wires onto the magnetic ring.

[0003] When winding the magnetic rings of a network transformer, it is not convenient to adjust and fix them according to different sizes of magnetic rings, which will reduce the efficiency of the winding and affect the performance. Utility Model Content

[0023] Example:

[0024] Reference Figures 1-4A winding assembly for a network transformer includes a base 1, on which a circular ring 102 for winding is rotatably mounted. A vertical plate 101 is fixedly mounted on the base 1. Preferably, the circular ring 102 is rotatably mounted on the vertical plate 101. Multiple sets of circumferentially evenly distributed limiting wheels 103 are rotatably mounted on the vertical plate 101. Two to ten sets of limiting wheels 103 are provided, preferably three sets, evenly distributed circumferentially on the vertical plate 101. The outer wall of the circular ring 102 abuts against the outer wall of the limiting wheels 103. In use, by using the limiting wheels 103 to abut against the outer wall of the circular ring 102, the reliable rotation of the circular ring 102 is ensured, and its position is reliable, preventing it from falling off. A fourth gear is rotatably mounted on the vertical plate 101, meshing with the outer wall of the circular ring 102 to drive it. The ring 102 rotates to wind the wire. A third motor for driving the fourth gear is fixed on the vertical plate 101. A wire coil 104 is rotatably mounted on the inner wall of the ring 102. The fixing plates at both ends of the wire coil 104 are fixed to the inner wall of the ring 102 with screws. A notch is provided on the ring 102, and a retaining ring matching the ring 102 is detachably installed in the notch. It can be detached and connected to the ring 102 by clips or bolts. In use, by removing the retaining ring on the ring 102, it is easy to put the magnetic ring on the ring 102. Then, one end of the wire coil 104 is fixed to the magnetic ring. The third motor drives the fourth gear to rotate, which drives the ring 102 to rotate and wind the wire onto the magnetic ring. At this time, the guide wheel 4 can drive the magnetic ring to rotate accordingly, so that the coil is wound as evenly as possible, improving the performance. It also includes three sets of circumferentially distributed uprights 2, all of which are slidably mounted on the base 1. During use, the three sets of uprights 2 can move closer or further apart to fix and limit the magnetic ring. Each upright 2 has a guide wheel 4 rotatably mounted on its top, which abuts against the outer wall of the magnetic ring. A support plate 401 is fixedly mounted on the bottom end face of the guide wheel 4. A drive unit for driving the uprights 2 to slide is provided inside the base 1. During use, the drive unit can be activated to drive two sets of uprights 2 to move closer together. At this time, the magnetic ring is placed between the three sets of guide wheels 4, and the outer wall of the guide wheel 4 gradually abuts against the magnetic ring, and the bottom of the magnetic ring abuts against the support plate 401. At this time, the position of the guide wheel 4 can be adjusted according to the diameter of the magnetic ring to limit and fix magnetic rings of different diameters, thereby improving the user experience.

[0025] In use, by driving the disc 3 to rotate, the three sets of uprights 2 can be driven to move closer or further apart via the helical teeth 301, thereby fixing or loosening the magnetic ring. The adjustment is convenient and it is easy to fix magnetic rings of different diameters to achieve the winding effect and improve production efficiency. By setting an upper baffle 5 on the top of the guide wheel 4, the upper end of the magnetic ring can be limited, reducing the possibility of the magnetic ring slipping upward along the axial direction during the winding process and improving the winding effect.

[0026] Reference Figures 1-3 Three sets of guide grooves 105 evenly distributed in a circle are provided on the top end face of the base 1. Limiting blocks 201 are fixedly provided at the bottom of the upright 2. The three sets of limiting blocks 201 are slidably set in the corresponding guide grooves 105. In use, by providing guide grooves 105 on the base 1, the upright 2 can be reliably slid, and the limiting blocks 201 can be prevented from sliding off the base 1, thus improving the use effect.

[0027] Reference Figures 1-3 Here, the drive unit is designed with a disc 3 rotating within the base 1. A helical tooth 301 is fixedly mounted on the top surface of the disc 3, and the bottom of the limiting block 201 meshes with the helical tooth 301. A first motor is fixedly mounted within the base 1, and a first gear is fixedly mounted at the output end of the first motor, meshing with the outer wall of the disc 3. In use, by starting the first motor and rotating the first gear, the limiting blocks 201 can be driven to move closer or further apart via the helical tooth 301, thus fixing magnetic rings of different diameters and improving the performance. The principle is similar to the driving principle of the jaws on a three-jaw chuck.

[0028] Reference Figure 3 A second motor is fixedly installed on one of the uprights 2, and a second gear is fixedly installed at the output end of the second motor. A third gear is fixedly installed on one of the guide wheels 4. The second gear and the third gear are meshed. In use, the second motor is started to drive the second gear to rotate. The second gear meshes with the third gear, which can drive the current guide wheel 4 to rotate. This can realize the rotation of the magnetic ring to wind the wire during the winding process, so that the winding on the magnetic ring is as uniform as possible and the use effect is improved.

[0029] Reference Figure 3 and Figure 4 An upper baffle 5 is raised and lowered on the top of the guide wheel 4. The bottom of the upper baffle 5 abuts against the top of the magnetic ring. A limiting groove 402 is opened in the guide wheel 4, and a limiting plate 502 is slidably arranged in the limiting groove 402. The upper baffle 5 is fixedly connected to the limiting plate 502 through a connecting post 501, and a spring is sleeved on the connecting post 501. The two ends of the spring abut against the limiting groove 402 and the limiting plate 502 respectively. In use, by raising and lowering the upper baffle 5 on the top of the guide wheel 4, the magnetic ring can be limited from above, and magnetic rings of different thicknesses can also be limited, thus improving the use effect.

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.
