Transformer skeleton structure integrated with heat-conducting bridge

Abstract

This utility model discloses a transformer frame structure with integrated heat-conducting bridge, belonging to the field of transformer technology. It includes a winding frame and a protective cover mounted on the winding frame. Through the coordinated use of the above devices and the installation / removal mechanism, the grooves on both sides of the protective cover are aligned with the protrusions on both sides of the winding frame, allowing the inclined surfaces of the two inserts to contact the inclined surfaces at the top of the protrusions and be squeezed into the first mounting groove. At this time, the telescopic rod retracts, compressing the first spring. When the protective cover is in place, the spring force of the first spring ejects the inserts, allowing them to insert into the slots on both sides of the protrusions, thus achieving a stable installation. During disassembly, pressing the pressure plate moves the insert bar downwards, and the inclined surface of the insert bar pushes the inclined block, thereby moving the insert into the first mounting groove and removing it from the slot. This allows for easy removal of the protective cover, effectively reducing the contact between the wires and leads of the winding frame and the equipment's gripping mechanism during transfer.

Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically a transformer frame structure with integrated heat-conducting bridge. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. It mainly consists of a magnetic core, primary winding, secondary winding, frame, and pins. The frame is used to fix and support the windings and provide electrical insulation. The pins, as important interfaces for connecting to external circuits, are usually soldered onto a circuit board to ensure reliable current transmission. Transformers are widely used in power systems, electronic equipment, communication devices, and various power adapters, playing key roles in isolation, impedance matching, and voltage transformation. Existing transformer frames also integrate thermal bridges. The core function of thermal bridges on transformer frames is to establish an efficient "heat highway" that quickly conducts the heat generated inside the transformer to external heat sinks or the environment, thereby significantly reducing the operating temperature of the transformer.

[0003] After the metal wire is wound around the outside of the transformer frame, it is transferred by the automatic gripping mechanism of the transformer production machine, and then the quality is inspected manually. During the transfer of the winding frame, the wire wrapped around the outside of the frame may come into contact with the gripping mechanism of the equipment, causing the wire to break.

[0004] Therefore, this utility model provides a transformer frame structure with integrated thermal bridge to solve the above problems. Utility Model Content

[0005] This invention provides a transformer frame structure with an integrated thermal bridge, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transformer frame structure with integrated heat-conducting bridge, including a winding frame, and further including: a protective cover disposed on the winding frame, protrusions fixedly installed on both sides of the winding frame, grooves formed on both sides of the protective cover that are adapted to the protrusions, and a loading and unloading mechanism disposed inside the grooves for installing and removing the protective cover.

[0007] The loading and unloading mechanism includes a first mounting groove formed on the inner walls of both sides of the groove, a telescopic rod fixedly installed on the inner wall of one side of the first mounting groove, an insert block fixedly installed on the movable end of the telescopic rod, a first spring sleeved on the side surface of the telescopic rod, slots formed on both sides of the protrusion for the insert block to be inserted, inclined blocks fixedly installed on both sides of the insert block, an insert strip slidably installed inside the first mounting groove, and a pressure plate fixedly installed on the top of the insert strip.

[0008] Preferably, the insert extends through the first mounting groove, and the insert is elastically connected to one side inner wall of the first mounting groove by a first spring.

[0009] Preferably, the inclined surface of the insert is in contact with the inclined surface of the inclined block, and the insert passes through the first mounting groove.

[0010] Preferably, a second mounting groove is provided at the bottom of the first mounting groove, and a pad is fixedly connected to the bottom of the insert, the pad being slidably connected inside the second mounting groove.

[0011] Preferably, a second spring is provided inside the second mounting groove, and the pad is elastically connected to the bottom of the second mounting groove through the second spring.

[0012] Preferably, a base is provided below the winding skeleton, and pins are fixedly connected to the bottom of the base. Multiple pins are provided, and the pins are distributed in a linear array at the bottom of the base.

[0013] Preferably, a connecting plate is fixedly connected to one side of the base, and the end of the connecting plate away from the base is fixedly connected to one side of the winding frame, and a heat-conducting bridge is fixedly connected inside the winding frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to use. Through the setting of the loading and unloading mechanism, the grooves on both sides of the protective cover are aligned with the protrusions on both sides of the winding frame and inserted, so that the inclined surfaces of the two inserts contact the inclined surfaces on the top of the protrusions on both sides and are squeezed into the first mounting groove. At this time, the telescopic rod retracts and the first spring is compressed. When the protective cover is in place, the elastic force of the first spring pops the inserts out and inserts them into the slots on both sides of the protrusion, thereby achieving a stable installation. When disassembling, press the pressure plate, drive the insert bar to move downward, and the inclined surface of the insert bar pushes the inclined block, thereby driving the insert bar to move into the first mounting groove and remove it from the slot. The protective cover can then be easily removed, effectively reducing the contact between the wire and pins and the equipment gripping mechanism during the transfer of the winding frame.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 6 As shown, this utility model provides a transformer frame structure with integrated heat-conducting bridge. The transformer frame structure with integrated heat-conducting bridge includes a winding frame 1, and further includes: a protective cover 2 disposed on the winding frame 1, protrusions 3 fixedly installed on both sides of the winding frame 1, grooves 4 opened on both sides of the protective cover 2 and adapted to the protrusions 3, and a loading and unloading mechanism 5 disposed inside the grooves 4 for installing and removing the protective cover 2.

[0019] The loading and unloading mechanism 5 includes a first mounting groove 501 formed on the inner walls of both sides of the groove 4, a telescopic rod 502 fixedly installed on the inner wall of one side of the first mounting groove 501, an insert block 503 fixedly installed on the movable end of the telescopic rod 502, a first spring 504 sleeved on the side surface of the telescopic rod 502, slots 505 formed on both sides of the protrusion 3 for the insert block 503 to be inserted into, inclined blocks 506 fixedly installed on both sides of the insert block 503, an insert strip 507 slidably installed inside the first mounting groove 501, and a pressure plate 508 fixedly installed on the top of the insert strip 507.

[0020] The insert 503 passes through the first mounting groove 501, and the insert 503 is elastically connected to the inner wall of one side of the first mounting groove 501 by the first spring 504.

[0021] The inclined surface of the insert 507 fits into the inclined surface of the inclined block 506, and the insert 507 passes through the first mounting groove 501.

[0022] Using the above scheme: When using the transformer frame structure with integrated heat-conducting bridge, first place the winding frame 1 in a suitable position, wrap the metal wire around the outside of the winding frame 1, align the grooves 4 on both sides of the protective cover 2 with the protrusions 3 on both sides of the winding frame 1 and insert them directly. The inclined surfaces of the two inserts 503 will first contact the inclined surfaces at the top of the two sides of the protrusions 3, thereby pressing the two inserts 503 into the interior of the first mounting groove 501. At this time, the telescopic rod 502 retracts, and the first spring 504 is compressed. When the protective cover 2 is fully placed in place, under the elastic force of the first spring 504, the inserts 503... 3. The protrusion pops out and inserts into the slots 505 on both sides of the protrusion 3, so as to achieve a stable installation of the protective cover 2 and the winding frame 1. When it is necessary to remove the protective cover 2, press down the pressure plate 508. The pressure plate 508 drives the insert 507 to move downward. Since the inclined surface of the insert 507 is in contact with the inclined surface of the inclined block 506, the downward movement of the insert 507 will push the inclined block 506, thereby driving the insert 503 to move into the first mounting groove 501, so that the insert 503 is removed from the slot 505. The protective cover 2 can then be removed from the winding frame 1, which facilitates the installation and removal of the protective cover 2 and improves the ease of use.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in order to facilitate the resetting of the pressure plate 508, a second mounting groove 6 is provided at the bottom of the first mounting groove 501, and a pad 7 is fixedly connected to the bottom of the insert 507. The pad 7 is slidably connected inside the second mounting groove 6.

[0024] The second mounting groove 6 is equipped with a second spring 8, and the pad 7 is elastically connected to the bottom of the second mounting groove 6 through the second spring 8.

[0025] The above solution allows the transformer frame structure with integrated heat-conducting bridge to be used in such a way that when the pressure plate 508 is pressed down to move the insert 507 downward, if the pressure plate 508 is released, the pad 7 will move the insert 507 upward under the elastic force of the second spring 8, thereby restoring the pressure plate 508 to its initial position and preparing it for the next pressing operation. This design allows the pressure plate 508 to automatically reset after each pressing, without the need to manually pull it back to its original position, further improving the convenience of use and the smoothness of operation of the transformer frame structure.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, in order to dissipate heat from the metal wire, a base 9 is provided below the winding frame 1. Pins 10 are fixedly connected to the bottom of the base 9. Multiple pins 10 are provided, and the pins 10 are distributed in a linear array at the bottom of the base 9.

[0027] A connecting plate 11 is fixedly connected to one side of the base 9. The end of the connecting plate 11 away from the base 9 is fixedly connected to one side of the winding frame 1. A heat-conducting bridge 12 is fixedly connected inside the winding frame 1.

[0028] The above-mentioned solution is as follows: When the transformer skeleton structure with integrated heat-conducting bridge is in use, the metal wires wound on the winding skeleton 1 will generate heat when energized. The heat-conducting bridge body 12 has good thermal conductivity, and the heat can be dissipated to the surrounding environment more efficiently, thereby effectively reducing the temperature of the metal wires and avoiding the impact of excessive temperature on the performance and service life of the transformer skeleton structure. At the same time, the multiple pins 10 distributed in a linear array not only serve to fix the entire transformer skeleton structure, but also facilitate the connection of the transformer skeleton structure to circuit boards, etc., to ensure stable circuit conduction. The connecting plate 11 further enhances the connection stability between the base 9 and the winding skeleton 1, making the entire structure more robust and reliable.

[0029] Working principle and usage process of this utility model: When using the transformer frame structure with integrated heat-conducting bridge, firstly, the metal wire to be wound is evenly wound around the outside of the winding frame 1. During the winding process, attention should be paid to the neat arrangement of the wires to avoid crossing or other issues that may affect the performance. After winding, the grooves 4 on both sides of the protective cover 2 are aligned with the protrusions 3 on both sides of the winding frame 1 and inserted directly. The inclined surfaces of the two inserts 503 will first contact the inclined surfaces at the top of the two sides of the protrusions 3, thereby pressing the two inserts 503 into the interior of the first mounting groove 501. At this time, the telescopic rod 502 retracts, and the first spring 504 is compressed. When the protective cover 2 is fully in place, under the elastic force of the first spring 504, the inserts 503 pop out and insert into the slots 505 on both sides of the protrusions 3, achieving a stable installation of the protective cover 2 and the winding frame 1. During operation, the heat-conducting bridge 12 continuously conducts the heat generated by the metal wire away. During normal operation of the transformer frame structure, the heat-conducting bridge 12 continuously dissipates heat into the surrounding environment, ensuring that the metal wires are within a suitable temperature range. When it is necessary to repair the transformer frame structure or replace the protective cover 2, the protective cover 2 needs to be removed by pressing down on the pressure plate 508. The pressure plate 508 moves the insert 507 downward. Since the inclined surface of the insert 507 is in contact with the inclined surface of the inclined block 506, the downward movement of the insert 507 will push the inclined block 506, thereby moving the insert 503 into the first mounting groove 501, so that the insert 503 is removed from the slot 505. The protective cover 2 can then be removed from the winding frame 1. The whole process is convenient and quick, effectively improving the operability and maintenance convenience of the transformer frame structure in actual use. The transformer frame structure is fixed to the corresponding position on the circuit board by the pins 10 to ensure a stable connection.
