Description

Technical Field

[0001] The utility model relates to the technical field of inductor coils, in particular to an inductor coil skeleton. Background Art

[0002] An inductor coil is a device that works on the principle of electromagnetic induction. When current passes through a wire, a certain electromagnetic field is generated around the wire, and the wire of this electromagnetic field itself will have an inductive effect on the wires within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called self-inductance, that is, the changing current generated by the wire itself produces a changing magnetic field, which further affects the current in the wire. The effect on other wires within the range of this electromagnetic field is called mutual induction. In actual use, the wires are mostly wrapped around the coil frame to ensure the normal use of the coil.

[0003] However, the length of the current inductor coil bobbin is generally fixed. Special lengths, shorter or longer, need to be specially customized, which increases manufacturing costs and also makes the adaptation and use of the bobbin less flexible and more restrictive. Utility Model Content

[0021] See also Figures 1 to 4 In the present invention, the inductor coil skeleton includes two side edges 1, and the opposite sides of the two side edges 1 are fixedly connected with an inner slide 2 and an outer slide sleeve 3 respectively. One end of the inner slide 2 passes through and is slidably connected to the interior of the outer slide sleeve 3. The outer side of the inner slide 2 is provided with a ring-shaped hole row 4, and the holes of the hole row 4 are provided with an outward expansion mechanism 5. The interior of the outer slide sleeve 3 is provided with a tension mechanism 6, which extends to the interior of the inner slide 2 and is connected to it.

[0022] When the cam 3 is in the state of being stretched, the cam 3 is tightened and tightened, and the cam 3 is tightened to the left and right sides of the cam 3, so that the cam 3 is tightened and tightened, thereby the cam 3 is tightened and tightened.

[0023] See also Figure 2 and Figure 3 , wherein: the outward expansion mechanism 5 includes a first spring 51 and a protrusion 52, the bottom end of the first spring 51 is fixedly connected to the inside of the hole of the hole row 4, the other end of the first spring 51 is fixedly connected to the protrusion 52, and the outer side of the protrusion 52 is slidably connected to the inside of the hole of the hole row 4.

[0024] In the present invention, the first spring 51 maintains the thrust on the protrusion 52 so that it extends out of the hole position of the hole row 4. All the protrusions 52 form a winding support ring with an outer diameter consistent with the outer diameter of the outer sleeve 3, and the structure is flexible.

[0025] See also Figure 3 and Figure 4 , wherein: the end surface of the protrusion 52 away from the first spring 51 is an arc-shaped surface in side view.

[0026] In the present invention, the curved surface outside the protrusion 52 provides better and smoother support for the coil, making the coil winding smoother.

[0027] See also Figure 2 and Figure 3 , wherein: a spring piece 521 is fixedly connected to the bottom of the protrusion 52 , and the two spring pieces 521 have an outward expansion trend and the outer sides are in close contact with the inner walls of the holes of the hole row 4 .

[0028] In the present invention, after the protrusion 52 is lifted by the spring piece 521 , the spring piece 521 leaves the hole and expands outwards, staggered from the hole, to achieve reverse limit support and ensure stable support for the coil.

[0029] See also Figure 1, wherein: the pulling mechanism 6 includes a sliding rod 61 and a second spring 62, one end of the sliding rod 61 is fixedly connected to the interior of the outer sliding sleeve 3, the other end of the sliding rod 61 passes through the interior of the inner slide cylinder 2 and is slidably connected thereto, one end of the second spring 62 is fixedly connected to the interior of the inner slide cylinder 2, and the other end of the second spring 62 is fixedly connected to the sliding rod 61.

[0030] In the present invention, the slide rod 61 cooperates with the second spring 62 to pull the outer sleeve 3 and the inner slide cylinder 2 relative to each other, thereby maintaining the relative movement trend between the two, improving the compactness of the device and avoiding looseness.

[0031] See also Figure 1 , wherein: a slot 611 is opened inside the slide rod 61, and one end of the second spring 62 extends into the inside of the slot 611 and is fixedly connected to its inner wall.
