In this example, a vertical inductor includes a housing 1 and a coil assembly 2, wherein the coil assembly 2 is located inside the housing 1. Specifically, the coil assembly includes a mounting base 21, a U-shaped coil 22, and an I-shaped coil 23. The U-shaped coil 22 and the I-shaped coil 23 are both located on one side of the mounting base 21, and the I-shaped coil 23 is sleeved around the periphery of the U-shaped coil 22. Specifically, one end of the U-shaped coil 22 and the I-shaped coil 23 has an opening, both of which are facing one end of the housing 1. The U-shaped coil 22 has two first contact pins 221 on either side of the opening, and the I-shaped coil 23 has two second contact pins 231 on either side of the opening. The first contact pins 221 and the second contact pins 231 are both exposed from one end of the housing 1 to the outside of the housing 1 and serve as electrodes. When in use, the inductor is placed vertically on the circuit board. At this time, the coil assembly 2 is in an upright position, and the first contact pin 221 and the second contact pin 231 are both located at the bottom of the housing 1. The first contact pin 221 and the second contact pin 231 can be connected to the circuit board. It can be understood that because the coil assembly 2 is in an upright position and the "X"-shaped coil 23 is arranged on the periphery of the U-shaped coil 22, the U-shaped coil 22 and the "X"-shaped coil 23 overlap in the same plane. This not only greatly reduces the size of the inductor, but also realizes the simultaneous operation of two sets of circuits, greatly reducing the area occupied by the inductor on the circuit board. In this example, the housing 1 is formed in one piece using powder die-casting to improve the product's magnetic shielding effect.

[0022] Further, the mounting base 21 comprises a base body 211 and a mounting platform 212, the mounting platform 212 is arranged on one side of the mounting base 21, and the U-shaped coil 22 is sleeved on the mounting base 21, that is, during installation, the U-shaped coil 22 is sleeved on the mounting platform 212, so that the U-shaped coil 22 is quickly positioned, the production efficiency of the product is improved, and meanwhile, during the molding of the shell 1, the mounting platform 212 can also prevent the U-shaped coil 22 from being deviated, and the stability of the product is improved.

[0024] Further, the two second contact feet 231 are bent away from each other at the opening of the second contact foot 23, each second contact foot 231 has a second contact surface 2311 on the side away from the mounting platform 212, the second contact surface 2311 is exposed outside the shell 1 and flush with the first contact surface 2211, and the mounting base 21 further comprises two limiting platforms 213, the two limiting platforms are arranged on both sides of the base body 211 and close to one end of the second contact foot 23, and one end of each limiting platform 213 respectively abuts on the side of the two second contact feet 231 away from the second contact surface 2211. Similarly, when the several-shaped coil 23 is installed, the several-shaped coil can also be quickly positioned, and the stability of the several-shaped coil during the molding of the shell 1 is improved. In this example, the first contact surface 2211 and the second contact surface 2311 are both formed into electrodes by electroplating, so that no additional pin is needed to connect the solder pad of the circuit board during use, the resistance is reduced, and the performance of the product is improved.

[0026] In specific implementation, the U-shaped coil and the several-shaped coil can be used for round copper wire, flat copper wire, square copper wire or coated copper wire, and can be flexibly used in different scenes to meet different performance requirements.
