Description

Technical Field

[0001] This utility model relates to the technical field of inductors, specifically to an adjustable inductor structure. Background Technology

[0002] The inductance of an inductor depends primarily on the number of turns in the coil, the winding method, the presence or absence of a magnetic core, and the material of the core. Generally, the more turns the coil has and the denser the winding, the greater the inductance. Coils with a magnetic core have a larger inductance than those without; and coils with a higher magnetic permeability also have a larger inductance.

[0003] Current inductors have multiple coils arranged between the positive and negative electrodes. Each coil requires a connecting piece, and copper busbars are used to connect and fix the connecting pieces with different numbers of turns to achieve adjustment. This method is not only cumbersome to install and remove, but also makes it impossible to precisely adjust the inductance value. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an adjustable inductor structure that is easy to assemble and disassemble and has high adjustment accuracy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable inductor structure, including a positive electrode, a negative electrode, and a coil disposed between the positive electrode and the negative electrode. The positive electrode and the negative electrode are fixed structures. The coil includes a spiral tubular body and connecting tubes located at both ends of the spiral tubular body. One connecting tube is rotatably electrically connected to the positive electrode, and the negative electrode is movably electrically connected to the spiral tubular body.

[0006] An adjustable inductor structure in this utility model is further configured such that: the negative electrode is a plate-shaped structure, including a fixed plate and a movable plate, a clamping hole is provided between the fixed plate and the movable plate, the spiral tubular body passes through the clamping hole, and the movable plate can move laterally and be locked, thereby changing the size of the clamping hole.

[0007] The adjustable inductor structure of this utility model is further configured such that: an adjusting screw is provided on the movable plate, and the front end of the adjusting screw is threadedly connected to the fixed plate.

[0008] An adjustable inductor structure in this utility model is further configured such that: a movable block is provided on the top of the positive electrode, the movable block is connected to the positive electrode by a fixing screw, an insertion hole is provided between the movable block and the positive electrode, and the connecting tube passes through the insertion hole.

[0009] One adjustable inductor structure in this invention is further configured such that the coil has a hollow water channel inside.

[0010] Compared with the prior art, the present invention has the following advantages: The above-mentioned adjustable inductor structure adopts a spiral inductor coil design, which not only eliminates the connecting piece structure between each turn of the coil, but also allows the inductance value to be adjusted simply by rotating the inductor coil. This adjustment method is linear adjustment, unlike the segmented adjustment currently used, so the adjustment accuracy is higher. Attached Figure Description

[0013] The adjustable inductor structure of this utility model will be further described in detail below through specific embodiments.

[0014] like Figure 1 As shown, an adjustable inductor structure includes a positive electrode 1, a negative electrode 2, and a coil 3 disposed between the positive electrode 1 and the negative electrode 2. The coil 3 has a hollow water channel inside. The positive electrode 1 and the negative electrode 2 are fixed structures. The coil 3 includes a helical tubular body 31 and connecting pipes 32 located at both ends of the helical tubular body 31. One connecting pipe 32 is rotatably electrically connected to the positive electrode 1, and the negative electrode 2 is movably electrically connected to the helical tubular body 31.

[0015] The negative electrode 2 has a plate-like structure, including a fixed plate 21 and a movable plate 22. A clamping hole 23 is provided between the fixed plate 21 and the movable plate 22. The spiral tubular body 31 passes through the clamping hole 23. The movable plate 22 can move laterally and lock, thereby changing the size of the clamping hole 23. An adjusting screw 24 is provided on the movable plate 22, and the front end of the adjusting screw 24 is threadedly connected to the fixed plate 21.

[0016] The top of the positive electrode 1 is provided with a movable block 4, which is connected to the positive electrode 1 by a fixing screw 5. An insertion hole is provided between the movable block 4 and the positive electrode 1, and the connecting tube passes through the insertion hole.

[0017] The working principle of this invention is as follows: During use, the fixing screw 5 on the movable block 4 at the top of the positive electrode 1 is loosened, and the adjusting screw 24 on the movable plate 22 of the negative electrode 2 is also loosened, allowing the coil 3 to rotate. As the coil 3 rotates, it generates a certain axial movement, thereby changing the number of turns of the coil 3 between the positive electrode 1 and the negative electrode 2, thus achieving linear adjustment of the inductance value. After adjustment, simply tighten the fixing screw 5 to lock and electrically connect the coil 3 to the positive electrode 1; tighten the adjusting screw 24 to lock and electrically connect the coil 3 to the negative electrode 2. Its spiral inductor coil 3 design not only eliminates the need for connecting pieces between each turn of the coil 3, but also allows for adjustment of the inductance value simply by rotating the inductor coil 3. This adjustment method is linear, unlike the segmented adjustment currently used, resulting in higher adjustment accuracy.

[0018] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
