Description

Technical Field

[0001] This utility model relates to the field of electronic devices, and in particular to a network transformer. Background Technology

[0002] As a key component in the field of electronic communication, network transformers are widely used in Ethernet interfaces, data transmission equipment, and other scenarios. Their main functions include signal isolation, impedance matching, and common-mode interference suppression, which directly affect the stability and transmission efficiency of communication systems. With the miniaturization and integration of electronic devices, the structural design of network transformers has an increasingly significant impact on production efficiency and performance.

[0003] Network transformers consist of a housing, T1 ring, T2 ring, and corresponding winding wires. In some models of network transformers, the T1 and T2 rings are arranged along the length of the housing, with the axis of the T1 ring arranged in the height direction and the axis of the T2 ring arranged in the length direction. Since the pin arrangement on the housing is fixed, and the T2 ring is located on the inside, especially in network transformers with multiple sets of T1 and T2 rings where the T1 ring is on the outside and the T2 ring is on the inside, the lead of the secondary winding of the T2 ring will cross multiple pins and wrap around the outermost pin. This causes the lead to become loose and displaced, making it difficult to adapt to automated winding and welding processes and restricting the improvement of production efficiency. Therefore, a new type of network transformer is urgently needed to solve the above problems. Utility Model Content

[0018] Reference Figures 1-4 In this utility model, the automated production of the network transformer includes magnetic winding, housing installation, and lead winding. Magnetic winding refers to winding the winding wires onto a magnetic ring to form the transformer. Housing installation refers to installing the transformer into a housing. Lead winding refers to winding the transformer's leads onto designated pins. Specifically: This utility model provides a network transformer, including a housing 10, a transformer T1 20, and a transformer T2 30, as shown in the figure. Figure 2 Transformer T1 20 includes T1 ring 21, T1 primary winding 22, T1 secondary winding 23, primary tap 24, and secondary tap 25. Transformer T2 30 includes T2 ring 31, T2 primary winding 32, and T2 secondary winding 33. (Refer to...) Figure 1 , Figures 3-4 The housing 10 is provided with a first pin 41, a second pin 42, a third pin 43, a fourth pin 44, a fifth pin 45 and a sixth pin 46 arranged on both sides in sequence.

[0019] Reference Figure 1 , Figures 3-4T1 ring 21 and T2 ring 31 are arranged at intervals along the length of the housing 10. The central axis of T1 ring 21 is arranged along the height of the housing 10, and the central axis of T2 ring 31 is arranged along the length of the housing 10. When winding the coils, one end of the primary winding 22 of T1 is wound around the first pin 41, the other end of the primary winding 22 of T1 is wound around the third pin 43, the primary tap 24 is wound around the second pin 42, the secondary tap 25 is wound around the fifth pin 45, the other end of the primary winding 32 of T2 is wound around the sixth pin 46, and the other end of the primary winding 32 of T2 is wound around the fourth pin 44. One end of the primary winding 32 of T2 is connected to one end of the secondary winding 23 of T1, and one end of the secondary winding 33 of T2 is connected to the other end of the secondary winding 23 of T1, thus forming a complete two-stage transformer T1 20 and transformer T2 30.

[0020] Furthermore, the housing 10 is provided with a lead wire groove 50 located on the side of the sixth pin 46 facing away from the fifth pin 45. When winding the lead wire, the other end of the primary winding 32 of T2 is first pulled through the lead wire groove 50 by the corresponding wire management device, and then extended from the outside of the sixth pin 46 to the fifth pin 45. Finally, the lead wire is wound onto the sixth pin 46 by the lead wire winding device. Since the lead wire groove 50 is located on the housing 10 and on the side of the sixth pin 46 facing away from the fifth pin 45, the lead wire will be restricted by the lead wire groove 50 and cannot move freely, which facilitates the automated winding of the lead wire in the subsequent stage.

[0021] Reference Figure 3 In the first embodiment of this utility model, the housing 10 is provided with eight pins arranged sequentially on both sides. Transformers T1 20 and T2 30 are set as one group.

The lead groove 50 is set on the side of pin number 8 facing away from pin number 7. Specifically, when winding the pins, one end of the primary winding 22 of T1 is wound around pin number 1, and the other end of the primary winding 22 of T1 is wound around pin number 22. The primary tap 24 is wound around pin number 3, the secondary tap 25 is wound around pin number 7, the other end of the primary winding 32 of T2 is wound around pin number 8, and the other end of the primary winding 32 of T2 is wound around pin number 6. One end of the primary winding 32 of T2 is connected to one end of the secondary winding 23 of T1, and one end of the secondary winding 33 of T2 is connected to the other end of the secondary winding 23 of T1.

[0023] Specifically, the T1 and T2 rings on the left, along with their corresponding windings, belong to the first group of transformers. The T1 and T2 rings on the left, along with their corresponding windings, belong to the second group of transformers. When winding the primary winding 22 of the first group of transformers, one end of the primary winding 22 of T1 is wound onto pin number 1; the other end of the primary winding 22 of T1 is wound onto pin number 3; the primary tap 24 of the first group of transformers is wound onto pin number 2; the secondary tap 25 of the first group of transformers is wound onto pin number 15; and so on. The other end of the T2 primary winding 32 is wound around pin number 16, and the other end of the T2 primary winding 32 of the first transformer is wound around pin number 14. One end of the T2 primary winding 32 of the first transformer is connected to one end of the T1 secondary winding 23 of the first transformer, and one end of the T2 secondary winding 33 of the first transformer is connected to the other end of the T1 secondary winding 23 of the first transformer. The lead wire swaying at the other end of the T2 primary winding 32 of the first transformer is limited by the lead wire groove 50 outside pin number 16.

The lead wire swaying at the other end of the primary winding 32 of the second transformer T2 is limited by the lead wire groove 50 outside pin number 9.

[0025] It should be noted that this utility model can also be applied to network transformers with 3, 4 or even more T1 rings and T2 rings. This will not be elaborated here, nor should it be considered as a limitation of this utility model. In more embodiments, it is sufficient to open a corresponding lead groove 50 on the outside of the pin wound at the other end of the T2 primary winding 32.

[0026] Reference Figure 1 , Figures 3-4 In some embodiments, the bottom of the housing 10 is provided with a first protrusion 61 and a second protrusion 62 arranged on both sides of its length direction. The bottom surfaces of the first protrusion 61 and the second protrusion 62 are flush with or slightly higher than the bottom surface of the pin, which can support the entire network transformer.
