Description

Technical Field

[0001] The utility model relates to the technical field related to high-frequency transformers, in particular to a high-frequency transformer with a wire bundle structure. Background Art

[0002] The high-frequency transformer is the most important component of the switching power supply. There are many topological structures in the switching power supply. For example, in the half-bridge power conversion circuit, when working, the two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, which is then transformed through a high-frequency transformer to output alternating current. The ratio of the number of turns of each winding coil of the high-frequency transformer determines the output voltage. Therefore, when producing high-frequency transformers in the existing market, multiple sets of coils are generally wound according to the needs of use. When winding the coils, insulating tape is generally used to wrap them in the middle to achieve the effect of wiring protection for the coils. However, when winding the coils in the existing market, the surface of the coils is often unevenly wound. The coil often bulges out or sinks, which results in the tape not being able to completely contact the surface of the coil during subsequent winding. The tape will become loose after long-term use, affecting the normal use of the transformer. Therefore, a wire bundling device is needed to bundle the coils. However, the existing wire bundling devices on the market can only bundle the wires from above, and cannot squeeze and flatten the surface of the coil. This results in an unsatisfactory wire bundling effect, such as the setting of a moving disk that moves up and down in a high-frequency transformer with a wire bundling structure disclosed in Application No. 202323086123.5. Utility Model Content

[0003] The purpose of the utility model is to provide a high-frequency transformer with a wire bundling structure to solve the problem raised in the above background technology that the wire bundling device currently on the market can only perform wire bundling work on the upper side when bundling the wires, and cannot squeeze and flatten the surface of the coil, thereby resulting in an unsatisfactory wire bundling effect.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A high-frequency transformer with a wire bundle structure includes a mounting top plate, which is arranged in a rectangular structure and is arranged at the top of the entire high-frequency transformer for bolt installation with the outside world;

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5, the utility model provides a technical solution: a high-frequency transformer with a wire harness structure, comprising a mounting top plate 1, which is arranged in a rectangular structure, arranged at the top of the entire high-frequency transformer, and used for bolt installation between the outside world;

[0029] The bottom wiring board 2 is also arranged in a rectangular structure, and is arranged at the bottom of the entire high-frequency transformer, and is used for wiring work and installation work between the outside world. The top of the bottom wiring board 2 is provided with four slide grooves 21 distributed at equal angles;

[0030] The frequency conversion coil body 4 is arranged between the mounting top plate 1 and the bottom wiring plate 2;

[0031] Also includes;

[0032] The wire harness body 3 has four rectangularly distributed parts outside the frequency conversion coil body 4, and is used to harness the coils and tapes on the frequency conversion coil body 4. A squeezing mechanism 6 is also provided at the top of the wire harness body 3, and is used to squeeze the surface of the wound frequency conversion coil body 4 to achieve the effect of fastening the wire harness;

[0033] The frequency conversion coil body 4 includes:

[0034] The winding top plate 41 is arranged in a circular structure, and a servo motor 5 is bolted to the middle position of the top thereof, and a mounting top plate 1 is arranged at the top of the servo motor 5;

[0035] The winding center column 43 is arranged at the bottom of the winding top plate 41, and the top end is coaxially connected to the shaft in the middle of the servo motor 5, and the bottom bearing of the winding center column 43 is connected to the winding bottom plate 42;

[0036] Four fixing plates 31 are evenly distributed outside the winding bottom plate 42 and the winding top plate 41 .

[0037] A plurality of coils 44 are respectively wound around the outside of the winding center column 43 , and adhesive tape 45 is provided between adjacent coils 44 .

[0038] The present application provides a high-frequency transformer with a wire bundle structure. Specifically, when it is used, first, the coil 44 that needs to be wound is wound on the top of the winding center column 43, and the servo motor 5 is started to drive the winding center column 43 to rotate between the winding top plate 41 and the winding bottom plate 42. When rotating, the coil 44 can be wound. After the winding of the coil 44 is completed, one end of the tape 45 is bonded to the outside of the wound coil 44 to control the winding center column 43 to rotate again. By rotating the wire harness body 3 times, the winding of the adhesive tape 45 can be completed. During the winding process, the harness body 3 can be controlled to reach a suitable position so that it can squeeze the outside of the coil 44 to ensure that no bulging occurs when the coil 44 is wound. At the same time, since an extrusion mechanism 6 is provided at the top of the harness body 3, it can be ensured that when the adhesive tape 45 is wound, the extrusion mechanism 6 can squeeze the adhesive tape 45 into the gap between the coils 44 to ensure that the adhesive tape 45 can be firmly contacted with the coils 44.

[0039] Among them, according to Figure 2-4 As shown, the harness body 3 includes:

[0040] A fixing plate 31 is provided at the upper and lower positions of the frequency conversion coil body 4. A reserved groove 32 is passed through the middle of the fixing plate 31. A telescopic cylinder 33 is provided at the inner side of the reserved groove 32.

[0041] The cable tie rod 34 has sliders 35 fixed to the tops of both sides, and the outer sides of the sliders 35 are connected to the outer sides of the telescopic cylinder 33;

[0042] The bottom of the slider 35 at the bottom of the cable tie rod 34 is arranged inside the slide groove 21 to slide;

[0043] Specifically, according to the winding position of the coil 44, it is necessary to start the telescopic cylinder 33 so that it can mobilize the slider 35 to move inside the reserved groove 32. When the slider 35 moves, the wire tie rod 34 therein will move toward the position of the winding center column 43 and move to a suitable position to wind the coil 44. The coil 44 can also be squeezed after winding to ensure that the surface of the coil 44 after winding will not be uneven.

[0044] Further, according to Figure 5 As shown, the squeezing mechanism 6 is evenly distributed at the top of the cable tie rod 34, and the squeezing mechanism 6 includes;

[0045] The through hole 61 is embedded in the interior of the cable tie rod 34, and the interior thereof is connected to the extrusion rod 63 via the extrusion spring 62, and the top end of the extrusion rod 63 is arranged in a conical structure;

[0046] Specifically, when the adhesive tape 45 is wound, since the extrusion rod 63 is continuously extended and retracted under the action of the extrusion spring 62, the conical structure at the top of the extrusion rod 63 can squeeze the adhesive tape 45 into the gap between the coils 44 and 44 when the adhesive tape 45 is wound, thereby ensuring that the coils 44 can be stably bonded to the adhesive tape 45.
