Description

Technical Field

[0001] This utility model relates to the field of coil frame technology, specifically a coil frame that is easy to wrap. Background Technology

[0002] The coil bobbin can fix and support the winding, ensuring that the winding maintains the correct shape and position during the winding process, thereby facilitating the installation and maintenance of the winding.

[0003] In the past, fixing the lead wires relied heavily on the experience and skill of workers, which led to human error and scattered lead wire positions. This caused problems for the subsequent connection of the coil and the stator, and in severe cases, the coil would break, rendering the product unusable. Traditional coil frames not only relied too much on the stability of workers, but also had the problems of single workstation and difficulty in learning. For an assembly line operation, instability and irreplaceability are not in line with the laws of efficient production. Traditional coil frames also relied too much on the binding force of tape, which required frequent wrapping of tape, increasing the difficulty of using the coil frame and reducing the installation stability between the coil frame and the lead wires. Utility Model Content

[0004] The purpose of this invention is to solve the problems of increased difficulty in using the coil frame and reduced installation stability between the coil frame and the lead wire, and to propose a coil frame that is easy to wrap.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a coil frame for easy wrapping, including a straight cylinder and a second ring. The rear end face of the straight cylinder is fixedly connected to the front face of the second ring. A wire control structure is connected to the front face of the straight cylinder. A bracket is connected to the upper front face of the wire control structure. A limiting structure is connected to the outer wall of both the second ring and the wire control structure.

[0007] Preferably, the control line structure includes a first ring, a groove, and an opening. The rear end face of the first ring is fixedly connected to the front face of the straight cylinder. A groove is machined on the upper left side of the front face of the first ring, and an opening is machined on the upper right side of the front face of the first ring.

[0008] Preferably, a curved plate is fixedly attached to the upper front side of the first ring.

[0009] Preferably, the front surface of the first ring is fixedly connected to the rear end face of the bracket, and the bracket is located below the curved plate.

[0010] Preferably, the limiting structure includes a concave plate and a screw. The inner walls of the concave plate are respectively fitted to the outer walls of the first ring and the second ring at their front and rear ends. The front and rear circular openings of the concave plate are respectively threaded to the outer wall of the screw. A handle is fixedly attached to the outer side of the screw.

[0011] Preferably, the inner sides of the outer walls of the plurality of screws are respectively threaded to the outer circular openings of the first ring and the second ring.

[0012] The present invention provides a coil frame that is easy to wrap, with the following advantages: The lead wire is guided through the right-side curved plate from top to bottom via a control structure. The passed portion is then pulled to the right, allowing the lead wire to pass through the opening. The lead wire is then wound around the outer wall of the straight cylinder. Once the winding requirement is met, the lead wire emerges from the slot and passes through the left-side curved plate from bottom to top. The lead wire is then placed inside the bracket. No tape is needed to control the lead wire, facilitating wrapping and reducing the difficulty of using the coil frame. This ensures the stability of the installation between the coil frame and the lead wire. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings: Example

[0019] Please see Figure 1-4 In this embodiment, a coil frame that is easy to wrap includes a straight cylinder 1 and a second ring 4. The rear end face of the straight cylinder 1 is fixedly connected to the front face of the second ring 4. A stator can be inserted into the inner wall of the straight cylinder 1. The model of the stator can be matched with the inside of the straight cylinder 1. A wire control structure 2 is connected to the front face of the straight cylinder 1. A bracket 5 is connected to the upper front face of the wire control structure 2. A limiting structure 3 is connected to the outer wall of both the second ring 4 and the wire control structure 2.

[0020] The control structure 2 includes a first ring 201, a groove 202, and an opening 203. The rear end face of the first ring 201 is fixedly connected to the front face of the straight cylinder 1. A groove 202 is machined on the upper left side of the front face of the first ring 201, which is a winding outlet. An opening 203 is machined on the upper right side of the front face of the first ring 201, which is a winding inlet. A bent plate 204 is fixedly connected to the upper front face of the first ring 201. The upper front face of the first ring 201 is fixedly connected to the rear end face of the bracket 5. The bracket 5 is located below the bent plate 204. The bracket 5 can be used with a wire pressing terminal. The type of wire pressing terminal is selected according to the usage requirements and can be matched with the bracket 5.

[0021] The lead wire is passed through the right-side curved plate 204 from top to bottom in the control structure 2. Then, the passed part is pulled to the right. Next, the lead wire passing through the curved plate 204 passes through the opening 203. Then, the lead wire is wrapped around the outer wall of the straight cylinder 1. When the lead wire reaches the winding requirement, the lead wire is brought out at the slot 202. The lead wire passes through the left-side curved plate 204 from bottom to top. Then, the lead wire is placed inside the bracket 5. No tape is needed to control the lead wire, which is convenient for wrapping the lead wire, reduces the difficulty of using the coil frame, and ensures the installation stability between the coil frame and the lead wire.

[0022] The limiting structure 3 includes a concave plate 301 and a screw 302. The front and rear ends of the inner wall of the concave plate 301 are respectively attached to the outer walls of the first ring 201 and the second ring 4. The front and rear round openings of the concave plate 301 are respectively threaded to the outer wall of the screw 302. The screw 302 rotates back and forth through the round opening of the outer wall of the concave plate 301 under force. A handle 303 is fixed to the outer side of the screw 302. The handle 303 facilitates the rotation of the screw 302. The inner sides of the outer walls of the multiple screws 302 are respectively threaded to the round openings of the outer walls of the first ring 201 and the second ring 4.

[0023] Working principle:

[0024] Coil bobbin usage:

[0025] Pass the lead wire through the right-side curved plate 204 from top to bottom, then pull the passed portion to the right. Next, pass the lead wire through the curved plate 204 through the opening 203. Then, wrap the lead wire around the outer wall of the straight cylinder 1. When the lead wire reaches the required winding position, let the lead wire emerge at the slot 202. Pass the lead wire through the left-side curved plate 204 from bottom to top. Then, place the lead wire inside the bracket 5. No tape is needed to control the lead wire, which facilitates the wrapping of the lead wire.

[0026] Coil bobbin winding control:

[0027] After the lead wire is wound around the outer wall of the straight cylinder 1, the inner ends of the two concave plates 301 are respectively attached to the outer walls of the first ring 201 and the second ring 4. Then, the handle 303, along with the screw 302, rotates inward through the concave plates 301, so that the inner sides of the outer walls of the multiple screws 302 are respectively connected to the outer circular openings of the first ring 201 and the second ring 4, thus fixing the position of the concave plates 301. The concave plates 301 can prevent the lead wire wound around the outer wall of the straight cylinder 1 from becoming loose. Example

[0028] Please see Figure 1-4 In this embodiment, a coil frame that is easy to wrap also includes a groove plate 6, and the rear end faces of the two groove plates 6 are respectively fixed to the left and right sides below the front of the first ring 201.

[0029] Working principle:

[0030] The inner wall of the slot plate 6 is machined with an opening, and the lead wire can pass through the inner wall of the slot plate 6 to complete the restriction and prevent the lead wire from swinging.
