Abstract
Claims
1. A network transformer, comprising a first magnetic ring, a second magnetic ring, at least one first winding, at least one second winding, at least one third winding, and at least one fourth winding; wherein at least one fourth winding and at least one first winding are twisted together to form a first stranded group, the first stranded group being wound around the first magnetic ring at least one turn; at least one second winding and at least one third winding are twisted together to form a second stranded group, the second stranded group having the same number of turns as the first stranded group wound around the first magnetic ring; the end of the first winding and the beginning of the third winding are twisted together on the outside of the first magnetic ring to form a first tap; the end of the second winding and the beginning of the fourth winding are twisted together on the outside of the first magnetic ring to form a second tap; the beginning of the second winding and the end of the fourth winding are twisted together on the outside of the first magnetic ring to form a third stranded group, the third stranded group being wound around the second magnetic ring at least one turn; wherein, Outside the first magnetic ring, the beginning of the first winding and the end of the third winding are wound in opposite directions around the two ends of the first stranded wire group and the two ends of the second stranded wire group.
2. The network transformer as described in claim 1, wherein, The number of first windings is at least two, and at least two of the first windings and the fourth winding are twisted together to form the first twisted wire group; the number of third windings is the same as the number of first windings, and at least two of the third windings are twisted together with the second winding to form the second twisted wire group; on the outside of the first magnetic ring, the ends of at least two of the first windings and the beginnings of at least two of the third windings are twisted together to form the first tap, the beginnings of at least two of the first windings are twisted together to form a first wire bundle, and the ends of at least two of the third windings are twisted together to form a second wire bundle, and the first wire bundle and the second wire bundle are wound in opposite directions around the two ends of the first twisted wire group and the two ends of the second twisted wire group.
3. The network transformer as described in claim 2, wherein, The first wire harness has a number of turns greater than or equal to 1 / 2 turn, the second wire harness has a number of turns greater than or equal to 1 / 2 turn, and the first wire harness and the second wire harness have the same number of turns.
4. The network transformer as described in claim 3, wherein, The number of turns of the first wire harness and the second wire harness is 1 / 2 turn; or, the number of turns of the first wire harness and the second wire harness is 1 turn.
5. The network transformer as described in any one of claims 1 to 4, wherein, The first strand and the second strand are wound around the first magnetic ring 3 to 7 times; and / or, the first strand is wound around the arc length region of the first magnetic ring with a corresponding central angle less than or equal to 240°.
6. The network transformer as described in any one of claims 1 to 4, wherein, The third stranded wire is wound around the second magnetic ring 3 to 5 times; and / or, the second stranded wire is wound around the arc length region of the second magnetic ring with a corresponding central angle less than or equal to 216°.
7. The network transformer as described in any one of claims 1 to 4, wherein, The network transformer also includes: a fifth winding, the first end of which is twisted together with the end of the second winding and the first end of the fourth winding to form the second tap, and the end of the fifth winding is twisted together with the first end of the second winding and the end of the fourth winding to form the third stranded wire group.
8. The network transformer as described in claim 7, wherein, The first and second stranded wire groups have the same degree of twist; and / or, in the first stranded wire group, the second stranded wire group, and the first tap, the twist rate of the twisted pair structure is 26 to 34 strands per inch, the twist rate of the twisted three structure is 16 to 24 strands per inch, and the twist rate of the twisted four structure is 16 to 20 strands per inch; and / or, the twist rate of the second tap is 16 to 24 strands per inch; and / or, the twist rate of the third stranded wire group is 12 to 16 strands per inch.
9. The network transformer as described in any one of claims 1 to 4, wherein, The end of the second tap has a solder joint area with a length of less than or equal to 6 mm.
10. The network transformer as described in any one of claims 1 to 4, wherein, The diameter of the first magnetic ring is greater than the diameter of the second magnetic ring; and / or, the radial thickness of the first magnetic ring is less than or equal to 5 mm; and / or, the gap between the first magnetic ring and the second magnetic ring is less than or equal to 2 mm.
