Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic coils, specifically to a coil frame and an electromagnetic coil. Background Technology

[0002] The coil bobbin, also known as a winding bobbin, spool, or wire frame, is a key component in electronic components, especially in electromagnetic devices such as inductors, transformers, and relays. An electromagnetic coil is a helical coil made of wire that can generate magnetic flux based on the principle of electromagnetic induction.

[0003] A search revealed Chinese patent publication number CN218069511U, which discloses an electromagnetic coil frame and an electromagnetic coil. This invention effectively solves the problem of poor winding tightness of the electromagnetic coil on the outside of the frame body due to the fixing of the upper and lower flanges to the frame body. The invention includes an inner frame, with a first flange installed at one end and a clamping assembly installed inside the first flange. A second flange is installed at the other end of the inner frame, and a wire exit assembly is installed inside the second flange. The clamping assembly includes a mounting groove on one side near the inner frame, with a pressure ring installed inside the mounting groove. Limiting holes are evenly spaced inside the pressure ring, and limiting rods are inserted into the limiting holes. The limiting rods are fixedly connected to the inner wall of the mounting groove. In this invention, the rotation of a first screw pushes the pressure ring towards the electromagnetic coil, causing the pressure ring to press the side of the electromagnetic coil tightly, thereby improving the winding tightness of the electromagnetic coil and thus improving the winding effect.

[0004] However, the coil frame cannot limit the position of the coil in time after the coil is wound, which makes the position of the coil easy to loosen after the winding work, thus reducing the efficiency of the coil frame and making the coil unable to be used effectively. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a coil frame and an electromagnetic coil, which solves the problem that the coil frame cannot promptly limit the position of the coil after winding, causing the coil to loosen after winding, thus reducing the efficiency of the coil frame and making the coil unusable.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a coil frame and an electromagnetic coil, including a winding roller and a coil, wherein the coil is wound around the outside of the winding roller, and fixed rings are respectively rotatably sleeved at both ends of the winding roller, and an arc-shaped block is fixedly installed between the two fixed rings and disposed below the winding roller.

[0007] Preferably, support plates are fixedly installed at both ends of the winding roller, and fixing rings are symmetrically arranged between the two support plates, so as to facilitate the rotation of the winding roller.

[0008] Preferably, the inner sidewall of the arc-shaped block is rotatably connected with protective rollers at equal intervals, and the distance between each roller and the sidewall of the winding roller is equal, thereby facilitating the protection of the coil.

[0009] Preferably, the distance between the protective roller and the sidewall of the winding roller is matched with the thickness of the coil after winding, so as to facilitate limiting the winding length of the coil.

[0010] Preferably, the protective rollers at both ends of the arc-shaped block are located on the top surface of the arc-shaped block, thereby enabling simultaneous protection of the coil and the arc-shaped block.

[0011] Preferably, each of the fixing rings has symmetrically arranged wire outlet holes inside, and the fixing rings do not contact the side wall of the support plate, thereby facilitating the wire outlet operation of the coil.

[0012] This invention provides a coil frame and an electromagnetic coil. It has the following beneficial effects: This coil frame and electromagnetic coil, when used, by setting an arc-shaped block, when the winding roller rotates during coil winding, can prevent the position of the arc-shaped block from moving under the action of coil winding. Thus, when the side wall of the coil is in contact with the arc-shaped block during coil winding, the limiting position can be effectively limited and pressed. This coil frame and electromagnetic coil, when used, can conveniently protect the coil during winding by the protective rollers that are equally spaced inside the side wall of the arc block, preventing the coil from being damaged by friction with the arc block.

[0014] In the diagram, 1 is the winding roller; 2 is the coil; 3 is the arc-shaped block; 4 is the fixing ring; 5 is the support plate; 6 is the wire outlet hole; and 7 is the protective roller. Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-3 This utility model embodiment provides a coil frame and an electromagnetic coil, including a winding roller 1 and a coil 2. The coil 2 is wound around the outside of the winding roller 1. Fixed rings 4 are rotatably sleeved at both ends of the winding roller 1. An arc-shaped block 3 is fixedly installed between the two fixed rings 4 and is located below the winding roller 1. Support plates 5 are fixedly installed at both ends of the winding roller 1, and the fixed rings 4 are symmetrically arranged between the two support plates 5. Protective rollers 7 are rotatably connected at equal intervals inside the side wall of the arc-shaped block 3, and the distance between them and the side wall of the winding roller 1 is equal. The distance between the protective rollers 7 and the side wall of the winding roller 1 matches the thickness of the coil after winding. The protective rollers 7 at both ends of the arc-shaped block 3 are located on the top surface of the arc-shaped block 3. The inside of the fixed rings 4 is symmetrically provided with wire outlet holes 6. The fixed rings 4 do not contact the side wall of the support plate 5.

[0017] It should be noted that, in this embodiment, as Figure 1-3 As shown, when the coil 2 is wound, it needs to be wound on the winding roller 1, and the support plates 5 on both sides are clamped by the external clamping device, so that the coil 2 is wound on the winding roller 1. When the winding roller 1 rotates, it will drive the position of the coil 2 to move and be evenly wound on the winding roller 1. As the coil is wound, the diameter between the winding roller 1 and the wound coil 2 will gradually increase until the side wall of the coil and the side wall of the protective roller 7 are in contact with each other, which can effectively protect the side wall of the coil and prevent damage caused by friction, thus improving the efficiency of the device.
