Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency transformers, in particular to an iron core winding structure of a high-frequency transformer. Background Art

[0002] A high-frequency transformer is a power transformer whose operating frequency exceeds the medium frequency. The transformer core winding is mainly composed of an iron core and a coil wound on it. The combination of the iron core and the winding constitutes a complete electromagnetic induction system, which realizes the conversion of electric energy between different voltage levels through the principle of electromagnetic induction. During the operation of the transformer, the alternating current generates a changing magnetic flux through the winding, which passes through the iron core, thereby inducing an electromotive force in the other winding, thereby increasing or decreasing the voltage.

[0003] When the coil is wound on the core of the existing high-frequency transformer, the coil head is generally fixed by a rubber band or a cable tie before winding. However, this fixing method has many operating steps, increases the workload, and is inconvenient to replace the coil. Utility Model Content

[0004] The purpose of the utility model is to provide a core winding structure of a high-frequency transformer to solve the problem proposed in the above-mentioned background technology that the coil head is fixed by a rubber band or a cable tie and then wound. This fixing method has many operating steps, increases the workload, and is inconvenient to replace the coil.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an iron core winding structure of a high-frequency transformer, comprising:

[0007] The main body mechanism comprises an iron core, and two sides of the inner wall of the iron core are symmetrically and movably connected with an iron core movable frame;

[0008] The first fixing mechanism includes a first mounting hole symmetrically opened on the outer wall of the core movable frame, a button is slidably connected to the inner wall of the mounting hole, a first spring is fixedly connected to the outer wall of one side of the button, a push frame is fixedly connected to the end of the first spring, and a first limiting hole is opened through the inner cavity of the push frame.

[0009] Furthermore, the outer wall of the iron core is wound with a coil, the outer wall of the iron core is fixedly connected with a mounting groove, and two sides of the outer wall of one side of the iron core are symmetrically fixedly connected with a support frame;

[0010] The end of the coil is threadedly connected to the inner wall of the button;

[0011] Furthermore, the inner wall of the installation groove is equidistantly fixedly connected with a shock absorbing spring, and both ends of the shock absorbing spring are fixedly connected with a damper fixedly connected to the installation groove and the outer wall of the core movable frame;

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. According to the utility model, when the coil is wound on the iron core, one end of the coil is threadedly connected to the inner cavity of the button, and the button is manually pressed. The button drives the first spring to be squeezed, and the first spring is stretched in the other direction to drive the push frame to move.

[0030] See also Figure 1-4 As shown, this embodiment is a core winding structure of a high-frequency transformer, including:

[0031] The main body mechanism 1 includes an iron core 101, and an iron core movable frame 104 is symmetrically and movably connected to the inner wall of the iron core 101 on both sides;

[0032] The first fixing mechanism 2 includes a first mounting hole symmetrically opened on the outer wall of the core movable frame 104, a button 201 is slidably connected to the inner wall of the mounting hole, a first spring 202 is fixedly connected to the outer wall of one side of the button 201, a push frame 203 is fixedly connected to the end of the first spring 202, and a first limiting hole is opened through the inner cavity of the push frame 203;

[0033] One end of the coil 102 is fixed by the button 201, and the movement of the button 201 drives the push frame 203 to move through the expansion and contraction of the first spring 202, and the movement of the push frame 203 drives the rebound of the second spring 205 to make the first limiting ball 204 extend out of the first mounting hole to limit the button 201;

[0034] The inner wall of the first limiting hole is slidably connected to a first limiting ball 204, and a second spring 205 is fixedly connected between the two first limiting balls 204;

[0035] Working principle: When the coil 102 is wound on the iron core 101, one end of the coil 102 is threadedly connected to the inner cavity of the button 201, and the button 201 is manually pressed. The button 201 drives the first spring 202 to be squeezed, and the first spring 202 is stretched in the other direction to drive the push frame 203 to move. The push frame 203 drives the first limiting ball 204 and the second spring 205 to move until the push frame 203 extends out of the first mounting hole. The second spring 205 rebounds to make the first limiting ball 204 extend out of the first limiting hole and contact the outer wall of the first mounting hole to limit the push frame 203, thereby limiting the button 201 and the head of the coil 102.

[0036] This step facilitates fixing one end of the coil 102 and facilitates the subsequent disassembly of the coil 102 .

[0037] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0038] The outer wall of the iron core 101 is wound with a coil 102, the outer wall of the iron core 101 is fixedly connected with a mounting groove 103, and two sides of the outer wall of one side of the iron core 101 are symmetrically fixedly connected with a support frame 106, and the end of the coil 102 is threadedly connected to the inner wall of the button 201;

[0040] The inner wall of the installation groove 103 is equidistantly fixedly connected with a shock absorbing spring 105, and both ends of the shock absorbing spring 105 are fixedly connected with a damper fixedly connected to the outer wall of the installation groove 103 and the core movable frame 104, and the core movable frame 104 is movably connected to the inner wall of the installation groove 103;

[0041] The iron core movable frame 104 is damped by the damping spring 105 and the damper combination, and the iron core movable frame 104 is used to provide damping protection for the coil 102;

[0045] The rotating frame 302 drives the push rod 303 to move, and the push rod 303 causes the second limiting ball 304 to extend from the second limiting hole to limit the fixed cylinder 301;

[0046] Working principle: Due to the change of magnetic field and the flow of current, the core winding structure is prone to vibration. The support frame 106 is used to stably support the core 101 to reduce the vibration during subsequent use. After the second installation hole is overlapped with the corresponding hole of the to-be-installed position, the fixed cylinder 301 is installed, and the rotating frame 302 is manually rotated to extend it into the fixed cylinder 301. The rotating frame 302 drives the push rod 303 to move, and the push rod 303 extends the second limiting ball 304 from the second limiting hole to contact the inner wall of the corresponding hole, thereby limiting the fixed cylinder 301.

[0047] This step can facilitate fixing the entire device at the location to be installed.
