Technical Field

[0001] This utility model relates to the technical field of inductors, and more particularly to a common-mode inductor. Background Technology

[0002] Inductors are currently used in switching power supplies, motherboards, tablets, and relays. However, the coils on both sides of an existing inductor generate magnetic fields that affect each other during the energization process, causing the inductor's quality to deteriorate during use. Utility Model Content

[0003] One objective of this invention is to provide a common-mode inductor by adding an insulating partition between the conductors on both sides to block magnetic lines of force, thereby enabling the conductors on both sides to operate independently.

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

[0005] A common-mode inductor includes a base bracket and a magnetic ring. Pins are fixed around the lower end of the base bracket. An arc-shaped groove is formed on the upper surface of the base bracket. The magnetic ring is fixed vertically in the arc-shaped groove. A first wire and a second wire are wound around the two sides of the magnetic ring, respectively. The two ends of the first wire and the two ends of the second wire are wound around the four pins, respectively. An insulating partition is provided between the first wire and the second wire, and the insulating partition is located at the center of the magnetic ring.

[0006] As a preferred technical solution, a wire groove is provided on the outer side of the base bracket, and both the first wire and the second wire pass through the wire groove.

[0007] As a preferred technical solution, the lower end of the base bracket is integrally formed with pads.

[0008] As a preferred technical solution, the magnetic ring is a cylinder with rounded edges.

[0009] As a preferred technical solution, the base bracket is provided with mounting holes, the pins pass through the mounting holes from top to bottom, and adhesive is used to connect the pins to the mounting holes.

[0010] As a preferred technical solution, an adhesive is used to connect the insulating partition and the magnetic ring.

[0011] As a preferred technical solution, the lower ends of the four pins are flush with each other at the same height.

[0012] The beneficial effects of this utility model are as follows: It provides a common mode inductor, which connects the base bracket to the area where it is needed by inserting pins, and the insulating partition in the middle of the magnetic ring blocks the magnetic lines of force on both sides, thus ensuring the normal use of the first conductor and the second conductor.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 2 As shown in this embodiment, a common-mode inductor includes a base bracket 1 and a magnetic ring 2. Pins 3 are fixed around the lower end of the base bracket 1. An arc-shaped groove 4 is formed on the upper surface of the base bracket 1. The magnetic ring 2 is fixed vertically in the arc-shaped groove 4. A first wire 5 and a second wire 6 are wound around the two sides of the magnetic ring 2, respectively. The two ends of the first wire 5 and the two ends of the second wire 6 are wound around the four pins 3, respectively. An insulating partition 7 is provided between the first wire 5 and the second wire 6. The insulating partition 7 is located at the center of the magnetic ring 2.

[0020] After the pins 3 are installed on the injection-molded base bracket 1, the first wire 5 and the second wire 6 are wound around the two sides of the magnetic ring 2 respectively. Then the magnetic ring 2 is placed upright in the arc-shaped groove 4 of the base bracket 1. After the two ends of the first wire 5 and the two ends of the second wire 6 are wound with the pins 3, an insulating partition 7 is inserted in the middle of the magnetic ring 2 to separate the first wire 5 and the second wire 6, thereby reducing the mutual influence between the first wire 5 and the second wire 6 during operation.

[0021] The outer side of the base bracket 1 is provided with a wire groove 8. The first wire 5 and the second wire 6 both pass through the wire groove 8, hiding the first wire 5 and the second wire 6 inside the wire groove 8, ensuring the integrity of the outer side of the base bracket 1, and the wires will not be affected by external contact.

[0022] The lower end of the base bracket 1 is integrally formed with pads 9 to support and elevate the inductor. The magnetic ring 2 is cylindrical with rounded corners 10 on its edges for better structural integrity and easier installation and use. The insulating partition 7 is connected to the magnetic ring 2 with adhesive. The base bracket 1 is provided with mounting holes, through which pins 3 pass from top to bottom. Adhesive is used to connect the pins 3 to the mounting holes, assembling the insulating partition 7 and the magnetic ring 2 together. The first wire 5 and the second wire 6 can also be bonded to the pins 3. The lower ends of the four pins 3 are flush at the same height. With the pins 3 at the same height, it is easier to solder when installed in a switching power supply, motherboard, tablet, or relay.

[0023] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
