Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to an inductive network transformer module. Background Technology

[0002] A network transformer is a type of transformer used in data communication and computer networks. It can convert electrical signals into digital signals and performs multiple functions in computer networks, including signal coupling, isolation, impedance matching, and electromagnetic interference suppression.

[0003] Traditional network transformers connect to the pins inside the housing by winding wires. This structure is not only slow to produce, but also increases the space occupied by the network transformer, especially for network transformers with a large number of pins.

[0004] See also Figure 1 As shown, this is a traditional network transformer structure, where A is the pin, B is the transformer body, and C is the housing. The pins A are set on the two side walls of the housing C, and the transformer body B is placed on a single plane. As the number of pins and transformer bodies increases, the area occupied by the network transformer housing will increase accordingly, which is not conducive to the compact design of the network transformer. Utility Model Content

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an inductive network transformer module 10 includes: a housing 100 and a transformer assembly 200. The housing 100 includes a base 110, on which a plurality of pin groups 111 are disposed. The transformer assembly 200 includes a bracket 210, an inner PCB (printed circuit board) 220, an inner transformer element 230, an outer PCB 240, and an outer transformer element 250. The bracket 210 is provided with an inner mounting area and an outer mounting area. The inner transformer element 230 is mounted on the inner PCB 220, and the outer transformer element 250 is mounted on the outer PCB 240. Each row of pin groups 111 extends to the inner mounting area and the outer mounting area. The inner PCB 220 is located on the inner mounting area and is connected to the pin groups 111. The outer PCB 240 is located in the outer mounting area and is connected to the pin groups 111.

[0026] It should be noted that by setting inner and outer layer mounting areas on the bracket 210 respectively, and placing the inner layer PCB 220 and inner layer transformer element 230 on the inner layer mounting area, and placing the outer layer PCB 240 and outer layer transformer element 250 on the outer layer mounting area, an inner and outer layer stacked structure is formed. This reduces the area occupied by the housing 100, thereby achieving a compact housing design. Furthermore, since traditional network transformers connect the coils on the transformer to the pins of the housing 100 through winding, and winding is usually done manually... The traditional wire-winding process results in low production efficiency. Therefore, in this invention, the inner transformer element 230 is mounted on the inner PCB 220 and connected to the pin group via the inner PCB 220. Similarly, the outer transformer element 250 is mounted on the outer PCB 240 and connected to the pin group via the outer PCB 240. In other words, the transformer element and the pin group on the housing 100 are connected via a PCB, replacing the existing wire-winding network transformer structure. Furthermore, surface mount technology enables more automated production, thus improving production efficiency. Please refer to [link to previous invention]. Figure 2 As shown, a 96-pin inductive network transformer module 10 is presented. In this 96-pin network transformer structure, two sets of transformer assemblies 200 are provided, each set mounted on a base 110. This achieves a compact design of the network transformer module by modularly integrating the components of the transformer assemblies 200. Furthermore, it should be noted that the number of transformer assemblies 200 can be adaptively adjusted according to the number of transformers and the number of pins.

[0027] Specifically, the pin group 111 includes an inner pin group 111a and an outer pin group 111b, which are respectively mounted on the bracket 210. The inner pin group 111a extends to the inner mounting area and connects with the inner transformer element 230; the outer pin group 111b extends to the outer mounting area and connects with the outer transformer element 250. Each row of pin groups 111 is neatly arranged, thereby further improving the overall compactness of the inductive network transformer module 10.

[0028] In one embodiment, the inner PCB 220 has a plurality of inner layer connection holes 221, and the inner layer pin group 111a includes a plurality of inner layer pins. Each inner layer pin is respectively housed in the inner layer connection hole 221. A conductive layer, such as a copper conductive layer, is provided on the hole wall of the inner layer connection hole 221. After the inner layer pins are connected to the inner layer connection holes 221, the inner layer pins and the inner layer connection holes 221 can be fixed by soldering, thereby ensuring the stability of the connection between the inner PCB 220 and the inner layer pin group 111a. Similarly, the outer PCB 240 has multiple outer connection holes 241, and the outer pin group 111b includes multiple outer pins. Each outer pin is housed in an outer connection hole 241. A conductive layer, such as a copper conductive layer, is provided on the wall of the outer connection hole 241. After the outer pins are connected to the outer connection holes 241, they can be fixed by soldering, thereby ensuring the stability of the connection between the outer PCB 240 and the outer pin group 111b.

[0029] In one embodiment, the bracket 210 includes an inner support 211 and an outer support 212. Support legs 212a are respectively provided on both sides of the outer support 212. The two support legs 212a are connected to the two sides of the inner support 211 to form an inner mounting area. The side of the outer support 212 away from the inner mounting area forms an outer mounting area. This allows the inner and outer mounting areas to form an inner-outer stacked structure, saving space occupied by the outer casing 100 and achieving a compact design for the inductive network transformer module.

[0030] In one embodiment, a clearance groove 222 is provided on the inner PCB 220, and the support foot 212a on one side of the outer support 212 is located in the clearance groove 222. In this way, the overall space occupied by the inductive network transformer module 10 can be further reduced, making the overall structure more compact.

[0031] In one embodiment, a first side mounting portion and a second side mounting portion are respectively provided on both sides of the inner PCB 220, and the inner layer transformer element 230 is respectively mounted on the first side mounting portion and the second side mounting portion. That is, the inner layer transformer element 230 is mounted on both sides of the inner layer PCB 220, thereby reducing the area occupied by the inner layer PCB 220 and further realizing the compact design of the inductive network transformer module 10. Specifically, an inner layer clearance cavity 211a is provided on the inner layer support 211, and the inner layer transformer element 230 mounted on the second side mounting portion is housed in the inner layer clearance cavity 211a, thereby realizing the compact design of the inductive network transformer module 10.

[0032] In one embodiment, the inner transformer element 230 includes an inner transformer body 231 and an inner common-mode inductor 232. Similarly, the outer transformer element 250 includes an outer transformer body 251 and a common-mode inductor 252. Both the outer transformer element 250 and the inner transformer element 230 are mounted on the PCB using surface mount technology. Since surface mount technology makes it easier to automate production, it can further improve production efficiency compared to the traditional network transformer structure that requires winding.

[0033] In one embodiment, the housing 100 further includes a top cover that is fastened to the base 110, thereby enabling the housing 100 to isolate and protect the transformer assembly 200 from external contamination of the internal transformer assembly 200.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
