Description

Technical Field

[0001] This utility model relates to the field of winding skeleton technology, specifically, to a multi-strand parallel-wound anti-displacement limiting skeleton. Background Technology

[0002] In the field of electronic component manufacturing, especially in the production of magnetic components such as high-frequency transformers, inductors, and common-mode chokes, multi-strand wire parallel winding technology is often used to reduce the skin effect, improve current carrying capacity, and optimize electromagnetic performance. The multi-strand parallel winding process requires that each strand of wire remain synchronous and in a fixed position during the winding process to avoid problems such as uneven number of turns, inter-turn short circuits, and degraded electrical performance caused by wire retraction, axial movement, or offset.

[0003] In the manufacturing process of multi-strand fine wire coils, traditional bobbins only provide basic winding space and lack the function of independent guidance and positioning of each strand of wire. This makes it easy for strands to cross, squeeze each other or be subjected to uneven force during winding, which in turn causes defects such as disordered arrangement and short circuit between turns, seriously affecting winding accuracy and product consistency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a multi-strand parallel-wound anti-displacement limiting skeleton. It solves the problem that traditional skeletons only provide basic winding space and lack independent guidance and positioning functions for each strand of wire, which leads to strand crossing, mutual compression or uneven force during winding, resulting in defects such as disordered arrangement and short circuits between turns, seriously affecting winding accuracy and product consistency.

[0005] To achieve the above objectives, this utility model provides a multi-strand parallel-wound anti-displacement limiting skeleton, including a central shaft and multiple winding shafts for winding wires. The multiple winding shafts are symmetrically fixedly connected to the central shaft. The central shaft is symmetrically fixedly connected to two first circular plates. Multiple wire channels are symmetrically opened on the two first circular plates and the central shaft. Each of the multiple winding shafts is fixedly connected to a ring plate. Each ring plate has a connection port. Each connection port is aligned with the port of the wire channel opposite to the first circular plate. A limiting component is provided in the port of each wire channel on the first circular plate. The limiting component is used to limit and prevent displacement of the wires passing through the wire channels.

[0006] Preferably, each of the limiting components includes a placement ring plate, a ring cylinder is fixedly connected to the placement ring plate, the ring cylinder is disposed in the wire channel, the ring cylinder has two symmetrical arc grooves, a limiting arc plate is disposed in the arc groove, a spring is fixedly connected to the limiting arc plate, and the end of the spring away from the limiting arc plate is fixedly connected to the inner wall of the arc groove.

[0007] Preferably, the limiting arc plate is made of rubber, and the limiting arc plate protects the wire.

[0008] Preferably, each of the winding shafts is fixedly connected to a second circular plate, and each of the second circular plates has a circular hole through which the wire passes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Symmetrically distributed winding shafts and conductor channels ensure uniform force distribution when multiple conductors are wound together, avoiding mutual interference. The central shaft provides overall rigid support and suppresses torsional displacement.

[0010] 2. By setting a limiting component at the entrance of the conductor channel, the limiting arc plate driven by the spring elastically clamps the conductor. After the conductor is inserted, frictional resistance is automatically generated, which effectively prevents the conductor from retracting or moving axially when the winding tension is released or the equipment vibrates, ensuring accurate positioning of the starting end.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4This embodiment provides a multi-strand parallel winding anti-displacement limiting skeleton, including a central shaft 1 and multiple winding shafts 2 for winding the conductor 3. The multiple winding shafts 2 are symmetrically fixedly connected to the central shaft 1. Considering that the traditional skeleton only provides basic winding space and lacks independent guidance and positioning functions for each strand of conductor 3, it is easy for strands to cross, squeeze each other or be unevenly stressed during winding, which in turn causes defects such as disordered arrangement and short circuit between turns. The central shaft 1 is symmetrically fixedly connected to two first circular plates 4. The two first circular plates 4 and the central shaft 1 are symmetrically provided with multiple conductor channels 5. The multiple winding shafts 2 are all fixedly connected to circular ring plates 6. Each circular ring plate 6 is provided with a connection port 7. Each connection port 7 is aligned with the port of the conductor channel 5 away from the first circular plate 4. Each conductor channel 5 is provided with a limiting component in the port on the first circular plate 4. The limiting component is used to limit and prevent displacement of the conductor 3 passing through the conductor channel 5.

[0015] In summary, the improvement of this embodiment lies in: The symmetrically distributed winding shafts 2 and conductor channels 5 ensure uniform force distribution when multiple conductors are wound together, avoiding mutual interference. The central shaft 1 provides overall rigid support and suppresses torsional displacement.

[0016] Based on the above, other structures also need to be disclosed in detail, such as: Please see Figure 4 During the winding process, the tension of the conductor 3 changes, causing the winding to loosen and the starting end to be inaccurately positioned. Therefore, the limiting components all include a placement ring plate 1001, and a ring cylinder 1002 is fixedly connected to the placement ring plate 1001. The ring cylinder 1002 is set in the conductor channel 5. The ring cylinder 1002 has two symmetrical arc grooves, and a limiting arc plate 1003 is set in the arc groove. A spring 1004 is fixedly connected to the limiting arc plate 1003. The end of the spring 1004 away from the limiting arc plate 1003 is fixedly connected to the inner wall of the arc groove. The limiting arc plate 1003 is made of rubber and protects the conductor 3. By setting the limiting components at the entrance of the conductor channel 5, the spring 1004 drives the limiting arc plate 1003 to elastically clamp the conductor 3. After the conductor is inserted, frictional resistance is automatically generated, which effectively prevents the conductor from retracting or axially moving when the winding tension is released or the equipment vibrates, ensuring accurate positioning of the starting end.

[0017] Please see Figures 1-3 Each winding shaft 2 is fixedly connected to a second circular plate 8, and each second circular plate 8 has a circular hole 9. The wire 3 passes through the circular hole 9. After the wire 3 is wound around the winding shaft 2 multiple times, its end passes out through the circular hole 9 of the second circular plate 8. In summary, the working principle of this solution is as follows: Eight strands of wire 3 enter through the wire channel 5 on the outside of the first circular plate 4. After being clamped by the limiting component, they enter the winding groove of the corresponding winding shaft 2 through the connecting port 7. After the wire 3 is wound multiple times on the winding shaft 2, the end of the wire 3 exits through the circular hole 9 of the second circular plate 8. When the wire 3 enters the wire channel 5, the limiting arc plate 1003 is pressed tightly against the surface of the wire 3 under the action of the spring 1004. The rubber arc plate generates frictional resistance to prevent the wire 3 from retracting or moving axially. When the wire 3 is subjected to vibration or tension, the limiting arc plate 1003 compensates for the displacement through elastic deformation. The spring 1004 further adjusts the clamping force to avoid damaging the insulation layer of the wire 3. The alignment design of the connecting port 7 and the wire channel 5 ensures that the wire enters the winding area without deviation. The symmetrically distributed winding shaft 2 and wire channel 5 ensure that the force is uniform when multiple strands of wire are wound together, avoiding mutual interference. The central shaft 1 provides overall rigid support and suppresses torsional displacement.
