Description

Technical Field

[0001] The utility model relates to the technical field of inductor products, in particular to a vertical SQ inductor. Background Art

[0002] In daily life, switching power supplies need to use power factor correction circuits to reduce reactive power in the circuit and improve the effect of power conversion. Inductors work with other components to reduce the phase difference between the fundamental current and voltage of the AC input and improve the electrical characteristics of the circuit. SQ inductors, as common-mode inductors, can be used to suppress the electromagnetic waves generated by high-speed signal lines from radiating outward. Conventional SQ inductors expose the magnetic core to the outside, so that factors such as electromagnetic induction affect the use of the inductor itself. The electromagnetic induction and coil effect generated during the operation of the inductor will be affected by the non-inductor part, resulting in reduced energy efficiency and shortened service life.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figure 1 to Figure 2 As shown, in this embodiment, a vertical SQ inductor includes a bottom shell 1, a first copper wire loop 2, a second copper wire loop 3, a front shell 4, a rear shell 5 and a magnetic core 6. The first copper wire loop 2 and the second copper wire loop 3 are respectively wound on both sides of the magnetic core 6, and the front shell 4 and the rear shell 5 are respectively closed and fixed from the front and back of the magnetic core 6 and clamp the magnetic core 6. The front shell 4 and the rear shell 5 form a shell, and a partition 7 passes through the middle of the shell. A placement cavity 8 is set in the middle of the bottom shell 1, and the shell is pressed into the placement cavity 8 from top to bottom.

[0018] During production, the front shell 4 in the front and the rear shell 5 in the rear are closed toward the middle, and the shell composed of the front shell 4 and the rear shell 5 covers the magnetic core 6, and then the first copper wire loop 2 and the second copper wire loop 3 are respectively wound around the two sides of the shell outside the magnetic core 6 in a winding manner. At this time, the first copper wire loop 2 is on the left side of the shell, and the second copper wire loop 3 is on the right side of the shell. Then the partition 7 is inserted into the middle of the shell to separate the first copper wire loop 2 from the second copper wire loop 3. Finally, the whole is placed into the bottom shell 1 from top to bottom for fixation to form a vertical inductor structure.

[0019] The front end and the rear end of the bottom shell 1 are integrally formed with a clamping column 9, and a limiting groove 10 is arranged on the inner side of the clamping column 9. The lower end of the partition 7 is inserted into the limiting groove 10, and the magnetic core 6 with the partition 7 is lowered from top to bottom. The lower end of the partition 7 is clamped in the limiting groove 10 front and back, which restricts the partition 7 from falling off.

[0020] Guide plate grooves 11 are provided at both upper and lower ends of the middle of the shell, and the partition plate 7 is inserted into the guide plate groove 11. When the partition plate 7 is inserted into the shell horizontally, it enters the middle of the shell under the guidance of the guide plate groove 11 to separate the copper wire rings on both sides.

[0021] A baffle 12 is formed on one side of the partition 7, and the baffle 12 is pressed on both sides of the front shell 4. The baffle 12 limits the position of the partition 7 to the middle of the shell without being uncertain in the front and back positions, thereby ensuring smooth installation.

[0022] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
