[0031] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.

[0032] Please refer to Figs. 1 to 4 The novel pulse transformer of this application includes a magnetic core 1, a winding coil 2, and an electrode group 3.

[0033] In specific implementation, the magnetic core 1 includes a central column 11 and flanges 12 connected to both ends of the central column 11. The winding coil 2 is wound on the central column 11, and several lead wire connectors 21 extend from both ends of the winding coil 2. The electrode group 3 is respectively disposed on the flanges 12 at both ends of the central column 11, including C-type electrodes 5 arranged at intervals on the same flange 12. The lead wire connectors 21 are electrically connected to each C-type electrode 5 at the top and / or bottom of the flange 12. Alternatively, the electrode group 3 includes L-type electrodes 4 and C-type electrodes 5 arranged at intervals on the same flange 12. The lead wire connectors 21 are electrically connected to each L-type electrode 4 at the top of the flange 12 and to each C-type electrode 5 at the top and / or bottom of the flange 12.

[0034] In one application scenario, the spaced C-type electrodes 5 allow the lead connectors 21 at both ends of the winding coil 2 to selectively connect to each C-type electrode 5 at the top and / or bottom of the flange 12, thus streamlining the lead arrangement and avoiding the overlap or crossing of traditional lead connectors when connecting to electrodes. In another application scenario, L-type electrodes 4 and C-type electrodes 5 are spaced apart on the same flange 12, allowing the lead connectors 21 to connect electrically to the L-type electrode 4 at the top of the flange 12 and to the C-type electrode 5 at the top and / or bottom of the flange 12. This design structure avoids the overlap or crossing of traditional lead connectors when connecting to electrodes, effectively ensuring the withstand voltage performance of the winding coil and thus improving the overall reliability of the device.

[0035] It is understood that among the several lead connectors 21 extending from both ends of the winding coil 2, there may be two end connectors of the primary winding coil, two end connectors of the secondary winding coil, and a pair of center taps for the primary and secondary winding coils. In this embodiment, the structural design of the C-type electrode 5 or the combination of L-type electrode 4 and C-type electrode 5 of the novel pulse transformer can reasonably lead out the end connectors and center taps of the primary and secondary windings and connect them to the electrode group 3. This not only optimizes the electrical connection structure between the windings, but also reduces the risk of lead crossing and overlapping, thereby improving the withstand voltage performance of the pulse transformer and ensuring the stability and reliability of the network transformer in high-frequency, high-power operating environments. At the same time, this lead layout is suitable for automated assembly, further improving product consistency and production efficiency.

[0036] The novel pulse transformer of this application embodiment also includes a magnetic cover plate 6, which is connected to the flanges 12 at both ends of the central column 11 to form a closed loop with the magnetic core 1. It can be understood that the magnetic cover plate 6 maintains a clearance between itself, the central column 11 and the winding coil 2, and the bottom end of the flange 12 in this embodiment can be regarded as the end connected to the magnetic cover plate 6, while the top end of the flange 12 is the end away from the magnetic cover plate 6.

[0037] Among them, the C-type electrode 5 at the top of the flange 12 and the magnetic cover plate 6 facing the flange 12 have a preset gap. The preset gap can serve as a clearance space, which helps to prevent the lead connector 21 on the C-type electrode 5 from directly contacting the magnetic cover plate 6.

[0038] In one embodiment, the flange 12 can be designed as a rectangular structure. The flange 12 not only facilitates precise matching with the central column 11 and the magnetic cover plate 6 to form a stable closed magnetic circuit, but also provides a good installation platform for the arrangement of C-type electrodes 5 or the combination and snapping of L-type electrodes 4 and C-type electrodes 5. This makes the layout between electrodes clearer and more regular, thereby reducing the crossing and overlapping of lead wire connectors 21, and further ensuring the withstand voltage effect of the winding coil and the reliability of the electrical connection.

[0039] In one embodiment, a first functional groove 13 is provided on the side of the flange 12 away from the central column 11. The first functional groove 13 extends to the top and bottom of the flange 12. The C-shaped electrode 5 is fastened to the first functional groove 13, thereby ensuring the positional stability and assembly accuracy of the electrode during the installation process. That is, the design of the first functional groove 13 provides a dedicated space for fixing the electrode, so that the C-shaped electrode 5 can be accurately assembled therein, avoiding displacement or loosening of the electrode during operation.

[0040] In one application scenario, when the lead connector 21 is connected to the C-shaped electrode 5 in the first functional groove 13, the lead connector 21 can maintain a height difference with the bottom of the flange 12. That is, under the action of the first functional groove 13, the bottom of the groove extending to the bottom of the flange 12 can form a clearance space relative to the flange 12, which facilitates the placement of the lead connector 21 on the C-shaped electrode 5.

[0041] Furthermore, a second functional groove 14 is provided on the side of the flange 12 away from the central column 11. The second functional groove 14 extends to the top of the flange 12, and the L-shaped electrode 4 is fastened to the second functional groove 14, thereby facilitating the electrical connection of the lead connector 21 to the L-shaped electrode 4 at the top of the flange 12.

[0042] The first functional slot 13 and the second functional slot 14 are arranged alternately.

[0043] In specific implementation, the C-type electrode 5 may include a first main body 51 attached to the side of the flange 12, and a first connecting part 52 attached to the top and bottom of the flange 12 respectively. The lead wire connector 21 is welded to the first connecting part 52 at the top and / or bottom of the flange 12. Through the structural design of the first main body 51 and the first connecting part 52, the C-type electrode 5 is stable in the installation position and is not easy to shift. It also increases the contact area of ​​the welding point, thereby enhancing the durability of the electrical connection.

[0044] Similarly, the L-shaped electrode 4 includes a second main body 41 attached to the side of the flange 12 and a second connecting part 42 attached to the top of the flange 12, with the lead connector 21 welded to the second connecting part 42.

[0045] The novel pulse transformer of this embodiment, through the arrangement design of the second connecting part 42 at the top of the flange 12 and the first connecting part 52 at the top and / or bottom of the flange 12, facilitates the corresponding connection of the lead connectors 21. In one application scenario, one of several lead connectors 21 is connected to the second connecting part 42 at the top of the flange 12, another is connected to the first connecting part 52 at the top of the flange 12, and the third is connected to the first connecting part 52 at the bottom of the flange 12. This avoids the overlapping or crossing of traditional lead connectors and electrodes, effectively ensuring the withstand voltage performance of the winding coil, thereby improving the overall reliability of the device.

[0046] It is understood that the first main body 51 and the first connecting part 52 can also be connected to the first functional slot 13, and the second main body 41 and the second connecting part 42 can also be connected to the second functional slot 14, which will not be elaborated here.

[0047] In conjunction with any of the foregoing embodiments, the electrode group 3 may include an L-shaped electrode 4 and two C-shaped electrodes 5. Specifically, an L-shaped electrode 4 and two C-shaped electrodes 5 are arranged at intervals on the same flange 12. The lead connector 21 is electrically connected to the L-shaped electrode 4 at the top of the flange 12, and the lead connector 21 is electrically connected to each C-shaped electrode 5 at the top and / or bottom of the flange 12, thereby optimizing the spatial arrangement of the lead connector 21 after it is led out from the winding coil 2 and avoiding the overlap or crossing of the lead connector and the electrode when they are connected.

[0048] Alternatively, electrode group 3 may consist of two L-shaped electrodes 4 and one C-shaped electrode 5. Specifically, two L-shaped electrodes 4 and one C-shaped electrode 5 are arranged at intervals on the same flange 12. Lead connector 21 is electrically connected to each L-shaped electrode 4 at the top of flange 12 and to the C-shaped electrode 5 at the top and / or bottom of flange 12.

[0049] In one embodiment, a functional groove 15 is provided on the side of the flange 12 facing the central column 11. The functional groove 15 extends to the top of the flange 12 and is located between the L-shaped electrode 4 and the C-shaped electrode 5. The lead connector 21 is electrically connected to the L-shaped electrode 4 or the C-shaped electrode 5 through the functional groove 15. With the auxiliary guidance of the functional groove 15, the lead connector 21 can smoothly pass through the groove to achieve electrical connection with the L-shaped electrode 4 or the C-shaped electrode 5, thus optimizing the spatial arrangement of the lead connector 21.

[0050] This application also provides a network transformer, which may include the pulse transformers of the above embodiments. Compared with related technologies, the network transformer of this embodiment can avoid the lead connectors from overlapping or crossing each other during the connection with the electrodes, thereby ensuring the withstand voltage effect of the winding coil and improving the reliability of the device.
