Description

Technical Field

[0001] This utility model belongs to the field of power electronics technology, and more specifically, it relates to a high-thin high-frequency transformer. Background Technology

[0002] In the field of power electronics, high-frequency transformers are core components for voltage conversion, energy transfer, and isolation, suitable for demanding applications such as new energy and consumer electronics. Existing high-frequency transformers mainly consist of a magnetic core, windings, a frame, an insulation system, and pins. The frame forms the basic framework, with the magnetic core embedded in it to form a closed magnetic circuit. The windings are wound on the frame and nested inside the magnetic core to achieve electromagnetic coupling. The insulation system is located between the winding layers and between the windings and the magnetic core and frame. The pins are fixed to the outside of the frame and connected to the winding leads. The frame positions the components relative to each other, enabling them to work together to complete high-frequency energy conversion.

[0003] Existing application number CN202221474916.7 discloses a high-frequency transformer, relating to the field of transformer technology. It includes a transformer body, a lower base plate, and an upper top plate. The transformer body is provided with pins and windings, which are inserted into a cavity formed by the transformer body, the lower base plate, and the upper top plate. A filter plate and a pull rod are inserted into the upper top plate. The filter plate includes a first connecting part, a second connecting part, and a third connecting part, arranged sequentially from top to bottom, with the dimensions of the first, second, and third connecting parts decreasing sequentially. The upper top plate is provided with an installation groove that mates with the second connecting part. Several insert rods are installed on the filter plate. This utility model provides a high-frequency transformer where the filter plate is easy to install and remove, facilitating regular cleaning of the filter plate. Removing the filter plate does not affect the protective function of the upper top plate and other components for the windings.

[0004] Based on the above, most existing high-frequency transformers are relatively tall and thick, while electronic products are trending towards thinner and smaller designs. The large size of transformers has become a bottleneck restricting the compact design of equipment. Moreover, the winding leads and pins are mostly connected by soldering. In electronic equipment subjected to severe vibration, significant temperature differences, or impacts, the solder joints are prone to failure due to process defects, differences in material thermal expansion, and continuous mechanical stress. This not only affects the normal operation of the equipment and poses potential safety hazards, but also makes troubleshooting difficult. Utility Model Content

[0008] Furthermore, the limiting component includes: a positioning groove, wherein two sets of positioning grooves are provided, and the two sets of positioning grooves are respectively opened on the outer side of the upper frame and the lower frame.

Multiple sets of snap-fit ​​grooves are provided, and multiple sets of snap-fit ​​grooves are respectively opened on the left and right sides of multiple sets of inclined grooves.

[0010] Furthermore, the limiting component also includes: a snap-fit ​​bracket and a sealing plate. The snap-fit ​​bracket is provided in two sets, and the two sets of snap-fit ​​brackets are respectively snapped into the bottom sides of the lower frame. The sealing plate is provided in multiple sets, and the multiple sets of sealing plates are respectively fixedly connected inside the two sets of snap-fit ​​brackets and respectively snapped into the multiple sets of snap-fit ​​slots.

[0011] Furthermore, the warning component includes: a hinge shaft and a limiting paddle; the hinge shaft is provided in multiple sets, and the multiple sets of hinge shafts are respectively hinged to the back of multiple sets of sealing plates; the limiting paddle is provided in multiple sets, and the multiple sets of limiting paddles are respectively fixedly installed on the outside of the multiple sets of hinge shafts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features a limiting component. The upper and lower frame frames limit the coil's position within the winding post enclosure. A positioning groove allows the magnetic core to sink into the inner side of the frame, reducing overall height and volume. L-shaped pins replace traditional vertical pins, further reducing space requirements and meeting the need for thinner electronic products. An inclined groove guides and separates multiple coil ends, preventing them from intertwining. A snap-fit ​​bracket engages a sealing plate in the snap-fit ​​groove, forming a closed protection and preventing short circuits caused by solder failure leading to the coil end detaching and contacting adjacent ends.

[0016] Secondly, this invention features a warning component. A limiting lever is mounted on the back of the sealing plate via a hinge shaft, and its rounded end design prevents damage to the coil tip. An elastic torsion spring drives the limiting lever to gently press the tip, reducing the risk of detachment. When the tip lifts due to solder failure, it rotates the limiting lever, triggering the trigger pin to press and activate the switch, causing the warning mechanism to light up immediately. This allows for direct visualization of the faulty pin location, solving the problem of difficult troubleshooting of traditional soldering failures.

[0017] This utility model has the advantages of reducing occupation, limiting protection, and fault warning, which improves the reliability of high-frequency transformers under vibration and temperature difference environments, reduces safety hazards, and facilitates rapid maintenance.

[0030] The limiting component includes: a positioning groove 201, which is provided in two sets, and the two sets of positioning grooves 201 are respectively opened on the outer side of the upper frame 2 and the lower frame 3.

[0031] The limiting component also includes: a sloping groove 301 and a snap-fit ​​groove 3011.

[0033] The specific usage and function of this embodiment are as follows:

[0034] After the coil 5 is wound around the outside of the winding post 4, the upper and lower ends of the winding post 4 are sealed by the upper frame 2 and the lower frame 3 to achieve stable positioning of the coil 5. Two sets of E-type magnetic cores 1 are respectively inserted into the outside of the upper frame 2 and the lower frame 3. With the pre-set positioning grooves 201 of the two, the assembly positioning accuracy is ensured, and the magnetic cores are sunk into the inner side of the frame, significantly reducing the overall height and volume. The multiple sets of L-shaped pins 6 fixed on the front and rear sides of the lower frame 3 further reduce the height and volume compared with the pins installed vertically on the lower frame 3. The ends of the coil 5 are guided by the inclined groove 301 and soldered to the outside of the L-shaped pins 6. The inclined groove 301 can separate multiple sets of ends and avoid cross-winding. The sealing plate 701 is driven by the snap-fit ​​bracket 7 to snap into the snap-fit ​​groove 3011, which can form a closed protection for the inclined groove 301, effectively preventing the end from lifting off due to solder failure and short-circuiting with adjacent ends.

[0035] Example 2:

[0036] Based on Example 1, such as Figures 1 to 6 As shown, it also includes:

[0037] Warning component, the warning component is set inside the lower skeleton 3.

[0042] When the sealing plate 701 is engaged in the slot 3011, the limiting lever 702 is hinged to the back of the sealing plate 701 via the hinge shaft 7021. The end of the limiting lever 702 is designed to be arc-shaped to avoid scratching damage to the end of the coil 5. The elastic torsion spring 7022 drives the limiting lever 702 to swing moderately with its elastic force, forming a gentle squeeze on the end of the coil 5 in the inclined slot 301, further reducing the risk of end detachment. If the end lifts in the stress release direction due to solder failure, it will simultaneously drive the limiting lever 702 to rotate around the hinge shaft 7021, thereby pushing the trigger pin 7023 to squeeze the trigger switch 7012. After the trigger switch 7012 is triggered, the warning mechanism 7011 connected to the wiring harness will light up immediately, which can intuitively locate the L-shaped pin 6 where the end has detached, realizing rapid warning and accurate troubleshooting of the fault.
