Description

Technical Field

[0001] This application relates to the field of winding technology, and more specifically, to an enameled wire winding coil. Background Technology

[0002] Enamelled wire coils are components made by winding enamelled wire into a coil of a specific shape according to certain rules. They are used in electronic components such as inductors and transformers. The winding of enamelled wire realizes the electromagnetic induction function and is a basic component in electronic equipment for realizing energy conversion or signal transmission.

[0003] Used enameled wire ends are often mixed in with the complex layers of wire on the surface of the winding spool. Workers have to spend a lot of time looking for the ends, which not only reduces work efficiency, but may also damage or tangle the enameled wire due to repeated searching.

[0004] In view of this, this application proposes an enameled wire wound coil. Utility Model Content

[0005] The purpose of this application is to provide an enameled wire wound coil that solves the technical problems in the background art.

[0006] This application provides a wire winding coil, including a winding drum, with an insertion hole on one side of the outer wall of the winding drum, and limiting mechanisms at both ends of the winding drum;

[0007] The two limiting mechanisms include limiting plates located at both ends of the winding drum. A slot is provided on the upper part of the outer wall of the limiting plate. A threaded hole communicating with the slot is provided on the outer wall of the limiting plate. A knob is rotatably connected to the inside of the threaded hole by a thread. One end of the knob is rotatably connected to a top plate, and the lower end face of the top plate is in contact with the lower part of the inside of the slot.

[0008] Optionally, the limiting plate has a through-hole for installation, a fixing ring is fixedly connected inside the installation hole, and multiple limiting blocks are fixedly connected to the inner wall of the fixing ring.

[0009] Optionally, both ends of the winding spool are fixedly connected to an extension ring, and the extension ring extends into the fixed ring.

[0010] Optionally, each of the two extension rings has a fixed ring fixedly connected to its far-away end faces.

[0011] Optionally, the outer wall of the extension ring is provided with multiple fixing grooves, and a locking block is slidably connected inside the fixing groove.

[0012] Optionally, the card block is internally fixedly connected with multiple springs, and the springs are fixedly connected to the fixing groove.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] 1. This application utilizes a slot on the limiting plate, providing a dedicated storage location for the enameled wire end. After use, the enameled wire end is placed into the slot for quick and easy re-use, eliminating the need for workers to search for the end amidst the complex layers of wire on the winding spool. Rotating the knob moves the top plate, achieving precise clamping of the enameled wire end via threaded transmission. This not only prevents accidental detachment of the end but also allows adjustment of the clamping force according to the thickness of the enameled wire, ensuring compatibility with different wire specifications and a stable and reliable fixing effect.

[0015] 2. This application utilizes a limiting plate that rotates, causing the limiting block on the inner wall of the fixed ring to contact the locking block on the extension ring via an inclined surface. A compressed spring temporarily inserts the locking block into the fixing groove. After passing the limiting block, the spring rebounds and locks the locking block, forming a unidirectional rotational constraint. This ensures that the limiting plate can only rotate in the winding and tightening direction, preventing the enameled wire from loosening due to external forces during use and ensuring tight winding of the enameled wire.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-3 This application provides an enameled wire winding coil, including a winding drum 1. A hole 2 is provided on one side of the outer wall of the winding drum 1, and a limiting mechanism 3 is provided at both ends of the winding drum 1. The two limiting mechanisms 3 include limiting plates 301 located at both ends of the winding drum 1. A slot 302 is provided on the upper part of the outer wall of the limiting plate 301. The slot 302 provides a dedicated storage position for the end of the enameled wire. The end of the enameled wire after use is placed into the slot 302 for easy and quick use later.

[0022] The outer wall of the limiting plate 301 has a threaded hole 303 that communicates with the slot 302. A knob 304 is rotatably connected to the inside of the threaded hole 303 via a threaded connection. One end of the knob 304 is rotatably connected to a top plate 305, and the lower end face of the top plate 305 is in contact with the lower part of the slot 302. This eliminates the need for workers to search for the wire end amidst the complex layers of wire wound on the surface of the winding spool 1. Rotating the knob 304 drives the top plate 305 to move, achieving precise clamping of the enameled wire end through threaded transmission. This not only prevents accidental detachment of the end but also allows adjustment of the clamping force according to the thickness of the enameled wire, ensuring compatibility with different wire specifications and a stable and reliable fixing effect.

[0023] The limiting plate 301 has a through-hole 306. A fixing ring 307 is fixedly connected inside the mounting hole 306. Multiple limiting blocks 308 are fixedly connected to the inner wall of the fixing ring 307. Both ends of the winding drum 1 are fixedly connected to extension rings 309, which extend into the fixing ring 307. Multiple fixing grooves 311 are formed on the outer wall of the extension ring 309. A locking block 312 is slidably connected inside the fixing groove 311. Multiple springs 213 are fixedly connected inside the locking block 312, and the springs 213 are fixedly connected to the fixing groove 311. When the limiting plate 301 rotates, the limiting block 308 on the inner wall of the fixing ring 307 and the locking block 312 on the extension ring 309 make contact through the inclined surface. The compression of the spring 213 causes the locking block 312 to temporarily enter the fixing groove 311. After passing the limiting block 308, the spring 213 rebounds and locks the locking block 312, forming a unidirectional rotation constraint. Ensure that the limit plate 301 can only rotate in the winding and tightening direction to prevent the enameled wire from loosening due to external force during use and to ensure that the enameled wire is tightly wound.

[0024] The two extension rings 309 are fixedly connected to the far ends of each other by a retaining ring 310, which plays a good limiting role and prevents the limiting plate 301 from falling off.

[0025] Working principle: Insert one end of the enameled wire into the insertion hole 2 on the winding drum 1, and then wind the enameled wire onto the winding drum 1. Later, after using the enameled wire, the end of the wire wound on the conventional winding drum 1 is not easy to find, and the staff needs to spend a lot of time looking for it. However, when using this enameled wire winding coil, the end of the enameled wire can be placed into the end slot 302 near the end, and the knob 304 inside the threaded hole 303 is rotated. The rotation of the knob 304 drives the top plate 305 to move until the top plate 305 holds one end of the enameled wire to prevent the end of the enameled wire from falling off. Putting the end of the enameled wire into the slot 302 makes it easy for the staff to quickly find the end of the enameled wire and use it quickly.

[0026] After the enameled wire end is fixed, rotate the limiting plate 301. The fixing ring 307 inside the mounting port 306 rotates on the extension rings 309 at both ends of the winding drum 1. Multiple limiting blocks 308 on the inner wall of the fixing ring 307 will pass through the locking block 312 on the extension ring 309. The inclined surface of the locking block 312 and the inclined surface of the limiting block 308 will contact each other. The limiting block 308 will push the locking block 312 into the fixing groove 311. At the same time, the spring 213 is compressed. After passing through one limiting block 308, the spring 213 rebounds, and the locking block 312 pops out from the fixing groove 311. During rotation, the plane of the locking block 312 contacts the plane of the limiting block 308. The plane of the locking block 312 abuts against the plane of the limiting block 308, thereby preventing multiple limiting blocks 308, fixing ring 307 and limiting plate 301 from rotating, so that the limiting plate 301 can only rotate in one direction. By rotating the limiting plate 301, the end of the enameled wire can be tightly wound to prevent the enameled wire from loosening.

[0027] 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.
