Description

Technical Field

[0001] This utility model relates to the technical field of inductors, and in particular to a short-circuit resistant dual magnetic ring inductor. Background Technology

[0002] Common mode inductors are typically used in network transformers. A conventional common mode inductor uses a magnetic ring with two wires wound on each side of the same magnetic ring. When the two wires are energized, they are prone to accidentally touching each other, causing a short circuit. Moreover, if a problem occurs on one side, the entire magnetic ring needs to be replaced. Utility Model Content

[0003] One objective of this invention is to provide a short-circuit protected dual-magnetic-ring inductor, wherein each of the two magnetic rings independently drives a single conductor, facilitating maintenance, and the two conductors are separated by a partition, thereby improving the short-circuit protection capability.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A short-circuit resistant dual-magnetic-ring inductor includes a base bracket, a first magnetic ring, and a second magnetic ring. The base bracket has a first cavity and a second cavity, with a partition between them. The lower ends of both the first and second cavities are arc-shaped. A first wire is wound around the first magnetic ring, positioned above the first cavity. A second wire is wound around the second magnetic ring, positioned above the second cavity. Pins are fixed to the lower end of the base bracket, and both ends of the first and second wires are connected to the pins.

[0006] As a preferred technical solution, the partition is integrally formed with the base support, and the partition is cuboid in shape.

[0007] As a preferred technical solution, a guide groove is provided on the outer side of the base bracket, the guide groove extends in a vertical direction, and both the first wire and the second wire pass through the guide groove.

[0008] As a preferred technical solution, adhesive is used to connect the first magnetic ring to the base bracket, the second magnetic ring to the base bracket, the first wire to the pin, and the second wire to the pin.

[0009] As a preferred technical solution, the number of pins is six, wherein three pins are installed at equal intervals along a straight line below the first wire, and the other three pins are installed at equal intervals along a straight line below the second wire.

[0010] The beneficial effects of this utility model are as follows: It provides a short-circuit-proof dual magnetic ring inductor, which is used in network transformers. Two magnetic rings are mounted on a base bracket to form a bidirectional filter and have the ability to protect against short circuits. This solves the problem of short circuits caused by direct power supply and makes it easier to disassemble when there is a problem with a single-sided conductor and maintenance is required.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 3 As shown in this embodiment, a short-circuit-proof dual-magnetic-ring inductor includes a base bracket 1, a first magnetic ring 2, and a second magnetic ring 3. The base bracket 1 is provided with a first cavity 4 and a second cavity 5. A partition 6 is provided between the first cavity 4 and the second cavity 5. The lower ends of the first cavity 4 and the second cavity 5 are both arc-shaped. A first wire 7 is wound on the first magnetic ring 2 and is located above the first cavity 4. A second wire 8 is wound on the second magnetic ring 3 and is located above the second cavity 5. A pin 9 is fixed at the lower end of the base bracket 1. Both ends of the first wire 7 and the second wire 8 are connected to the pin 9.

[0019] The first wire 7 is wound around the upper end of the first magnetic ring 2 and extends to both ends of the first wire 7. The second wire 8 is wound around the upper end of the second magnetic ring 3 and extends to both ends of the second wire 8. The injection-molded base bracket 1 is placed face up. The base bracket 1 has a partition 6 in the middle. The partition 6 has a first cavity 4 and a second cavity 5 on both sides. The first magnetic ring 2 is placed vertically in the first cavity 4, and the second magnetic ring 3 is placed vertically in the second cavity 5. The two ends of the first wire 7 and the two ends of the second wire 8 are connected to the pins 9 installed at the lower end of the base bracket 1 to form an inductor structure.

[0020] The partition 6 is integrally formed with the base bracket 1. The partition 6 is cuboid in shape. The structure of the partition 6 is integrally formed during the injection molding of the base bracket 1, making the structure more stable.

[0021] The outer side of the base bracket 1 is provided with a guide groove 10. The guide groove 10 extends vertically. The first wire 7 and the second wire 8 both pass through the guide groove 10. The first wire 7 extending from the first magnetic ring 2 and the second wire 8 extending from the second magnetic ring 3 are guided through the guide groove 10 and then connected to the pin 9, effectively protecting the wires from damage.

[0022] Adhesive is used to connect the first magnetic ring 2 to the base bracket 1, the second magnetic ring 3 to the base bracket 1, the first wire 7 to the pin 9, and the second wire 8 to the pin 9. The adhesive is used to assemble the first magnetic ring 2, the second magnetic ring 3, the base bracket 1, and the pin 9, thereby improving the stability of the structure.

[0023] In addition, in this product, there are six pins 9, of which three pins 9 are installed at equal intervals along a straight line below the first conductor 7, and the other three pins 9 are installed at equal intervals along a straight line below the second conductor 8.
