Abstract
Description
Technical Field
[0001] This utility model relates to the field of inductor technology, and in particular to an inductor that is easy to detach from its wires. Background Technology
[0002] An inductor is made by winding a conductor one turn after another around an insulating tube. The conductors are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. An inductor works on the principle of electromagnetic induction. When current flows through a conductor, an electromagnetic field is generated around that conductor, and this electromagnetic field itself induces an effect on other conductors within that field.
[0003] In the existing technology, the wires in the inductor coil are directly wound on the insulating tube. When the insulating tube or the core inside it fails, the whole thing can only be replaced, which results in a lot of waste. At the same time, because the wires are difficult to disassemble, the subsequent maintenance work is more troublesome and has certain limitations. Utility Model Content
[0004] The purpose of this invention is to provide an inductor coil that facilitates the removal of wires, so as to at least achieve the purpose of convenient wire removal.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An inductor coil with easily detachable wires includes a cylindrical core, multiple arc-shaped blocks circumferentially distributed on the outer wall of the cylindrical core and slidingly engaged with the outer wall of the cylindrical core, a limiting component that limits the arc-shaped blocks to the cylindrical core, and wires wound together around the outside of the multiple arc-shaped blocks; gaps exist between adjacent arc-shaped blocks.
[0007] Preferably, a slider is provided on the side of the arc-shaped block near the columnar core, and a groove is provided on the outer wall of the columnar core to slide with the slider, the length direction of the groove being the same as the length direction of the columnar core.
[0008] Preferably, the limiting component includes a limiting ring disposed at one end of the columnar core, and the limiting ring and the columnar core are threadedly connected; the end of the slide groove away from the limiting ring is not connected to the outside, and the end of the slide groove near the limiting ring is connected to the outside.
[0009] Preferably, each of the arc-shaped blocks has a first insertion hole on the side away from the limiting ring, the multiple first insertion holes are circular, each first insertion hole has a first insertion post, and the end of the first insertion post away from the first insertion hole is provided with a first ring; the first insertion post and the first insertion hole are interference-fitted.
[0010] Preferably, each of the arc-shaped blocks has a second insertion hole on the side near the limiting ring, the multiple second insertion holes are circular, each second insertion hole has a second insertion post, and the end of the second insertion post away from the second insertion hole is provided with a second ring; the second insertion post and the second insertion hole are interference-fitted.
[0011] Preferably, the surfaces of the first and second inserts are provided with an anti-slip insulating layer.
[0012] Preferably, the columnar core is a hollow insulating cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] By evenly distributing multiple identical arc-shaped blocks around the circumference of the outer wall of the columnar core, the wire can be wound around the outside of the multiple arc-shaped blocks. By making the multiple arc-shaped blocks slidably connected to the outer wall of the columnar core, when repairing or replacing the columnar core, the multiple arc-shaped blocks and the wire can slide out from the outer wall of the columnar core at the same time. After sliding out, because the adjacent arc-shaped blocks are gap-fitted, the arc-shaped blocks can separate from the wire and move freely inside the wire without the support of the columnar core. This achieves the purpose of separating the wire from the arc-shaped blocks and disassembling the wire from the surface of the columnar core.
[0015] By setting a limiting component to limit the arc-shaped blocks to the cylindrical core, after multiple arc-shaped blocks are slidably installed on the cylindrical core, the limiting component can limit the arc-shaped blocks to the cylindrical core, thus preventing the arc-shaped blocks from moving axially along the cylindrical core during inductor operation, which would have an adverse effect on the operation and performance of the inductor.

[0023] Example 1
[0024] An inductor coil with easily detachable wires, such as Figure 1 As shown, the device includes a columnar core 1, multiple arc-shaped blocks 2 (three blocks in this embodiment) evenly distributed around the outer wall of the columnar core 1 and slidingly engaged with the outer wall of the columnar core 1, a limiting component that limits the arc-shaped blocks 2 to the columnar core 1, and a wire (such as...) wound around the outside of the multiple arc-shaped blocks 2. Figure 1 (As shown); there are gaps between adjacent arc-shaped blocks 2. Further, as... Figure 2 and Figure 3 As shown, a slider 3 is provided on the side of the arc-shaped block 2 near the columnar core 1, and a groove 4 is provided on the outer wall of the columnar core 1 to slide in cooperation with the slider 3. The length direction of the groove 4 is the same as the length direction of the columnar core 1. Further, as Figure 1 As shown, the limiting assembly includes a limiting ring 5 disposed at one end of the cylindrical core 1, and the limiting ring 5 and the cylindrical core 1 are threadedly connected (e.g., Figure 2 As shown, the cylindrical core 1 has a threaded end on the surface of the limiting ring 5; as Figure 2 As shown, the end of the slide groove 4 furthest from the limiting ring 5 is not connected to the outside (to facilitate limiting the side of the arc-shaped block 2 furthest from the limiting ring 5), while the end of the slide groove 4 closest to the limiting ring 5 is connected to the outside. Further, as... Figure 3 As shown, the columnar core 1 is a hollow insulating cylinder. The arc-shaped block 2 is an insulator.
[0025] Working principle: First, install multiple arc-shaped blocks 2 one by one on the surface of the cylindrical core 1. Specifically, align the slider 3 on the arc-shaped block 2 with the groove 4 on the cylindrical core 1, and then push it into the groove 4. Next, thread the limiting ring 5 onto the end of the cylindrical core 1. After installation, the limiting ring 5 abuts against the arc-shaped block 2. Figure 1 As shown, the wires are then wrapped around the outside of multiple arc-shaped blocks 2 (the wrapping method is existing technology).
[0026] When the columnar core 1 needs to be repaired or replaced, first remove the limiting ring 5 from the end of the columnar core 1. Then, slide multiple arc-shaped blocks 2 along with the wires out from the outer wall of the columnar core 1. After sliding out, because the adjacent arc-shaped blocks 2 are in a clearance fit, the arc-shaped blocks 2 can separate from the wires and move freely inside the wires without the support of the columnar core 1. This achieves the purpose of separating the wires from the arc-shaped blocks 2 and removing the wires from the surface of the columnar core 1.
[0027] Example 2
[0028] In daily operations, when only routine maintenance or replacement of the columnar core 1 is required, and the wire does not need to be completely disassembled, it is not necessary to separate the wire and the arc-shaped block 2. However, in Embodiment 1, when the wire and the arc-shaped block 2 slide out simultaneously, the arc-shaped block 2 will spontaneously separate from the wire because it lacks the support of the columnar core 1. This results in the need to install the arc-shaped blocks 2 one by one on the outside of the columnar core 1 and rewrap the wire around the outside of the arc-shaped block 2 after the maintenance or replacement of the columnar core 1, making the operation extremely inconvenient.
[0029] Based on this, and building upon Example 1, as follows: Figure 4 As shown ( Figure 4 (The limiting ring 5 is not shown in the figure). Each of the arc-shaped blocks 2 has a first insertion hole (not shown in the figure, but the same as the second insertion hole 6; please refer to the figure for details) on the side away from the limiting ring 5. Figure 5 The multiple first sockets are concentric circles, and each first socket is provided with a first insertion post (not shown in the figure, but the same as the second insertion post 8; see reference for details). Figure 6 The first insertion post, at the end furthest from the first insertion hole, is provided with a first ring 10; the first insertion post and the first insertion hole are interference-fitted. Figure 4-6 As shown, each of the arc-shaped blocks 2 has a second insertion hole 6 on the side near the limiting ring 5. Multiple second insertion holes 6 are concentric, and each second insertion hole 6 contains a second insertion post 8. The end of the second insertion post 8 furthest from the second insertion hole 6 is provided with a second circular ring 9. The second insertion post 8 and the second insertion hole 6 are interference-fitted. Furthermore, the surfaces of the first insertion post and the second insertion post 8 are provided with an anti-slip insulating layer, such as a rubber layer.
[0030] Working principle: After the arc-shaped block 2 is installed onto the columnar core 1, the first and second inserts 8 on the first ring 10 and the second ring 9 are respectively interference-fitted into the first and second insertion holes 6. Figure 4As shown, the limiting ring 5 is then installed onto the cylindrical core 1. After installation, the limiting ring 5 abuts against the second ring 9. At this time, the multiple arc-shaped blocks 2, the first ring 10, the second ring 9, the first plug, the second plug 8, and the wires form a whole. When routine maintenance or replacement of the cylindrical core 1 is required, and the wires do not need to be completely disassembled, the limiting ring 5 is removed, and the entire assembly is simultaneously slid off the cylindrical core 1. After sliding off, the first plug hole on the first ring 10 is interference-fitted into the first plug hole, and the second plug hole 6 on the second ring 9 is interference-fitted into the second plug hole 6. The first ring 10, the first plug, the second ring 9, and the second plug 8 can support the multiple arc-shaped blocks 2, preventing the arc-shaped blocks 2 from separating from the wires. After maintenance or replacement, the entire assembly can be directly installed onto the cylindrical core 1. During installation, the slider 3 and the groove 4 cooperate. This solution allows multiple arc-shaped blocks 2 to be installed on the columnar core 1 simultaneously without the need for winding wires, making the operation simpler.
