[0003] Early common inductor designs often used the method of leading out pins from the bottom board. This design may have been a common and relatively simple implementation method at the time. However, as electronic devices became increasingly complex and diverse, this design gradually exposed some shortcomings.

[0004] In terms of operation, the structure of the baseboard lead pins may not be flexible and convenient enough. During installation and maintenance, specific tools and skills may be required to handle the pins, which increases the difficulty and time cost of operation. Moreover, this pin structure may not be compatible with modern automated production and assembly processes, which is not conducive to improving production efficiency and reducing production costs.

[0005] In terms of insulation, different components in electronic circuits need to be well insulated to prevent current leakage, electromagnetic interference and other problems. The inductor of the above structure cannot effectively isolate itself from the surrounding components, and thus cannot provide reliable insulation protection. This may lead to circuit failure, performance degradation and even safety hazards in the case of high circuit density and complex working environment.

[0006] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0014] As a further solution of the utility model: the bottom surface of the first conductive part is lower than or flush with the bottom surface of the insulating shell, and the bottom surface of the second conductive part is higher than the bottom surface of the insulating shell.

[0015] As a further solution of the utility model: a positioning structure is arranged between the magnetic core and the receiving groove to fix the magnetic core and the coil thereon in the receiving groove.

[0016] As a further solution of the utility model: the magnetic core is interference fit with the accommodating groove.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-2 In the embodiment of the utility model, an inductor structure with integrated patch and insulation functions includes an insulating shell 1, a concave receiving groove 2 is provided along the bottom end of the insulating shell 1, a magnetic core 3 and a coil 4 wound on the magnetic core 3 are arranged in the receiving groove 2, and a conductor is integrally fixed on the side of the bottom end of the insulating shell 1, and the conductor is horizontally extended;

[0029] The conductor includes a first conductive part 5 and a second conductive part 6 which are sequentially connected to the housing, and a lead wire 7 of the coil 4 extends out of the receiving groove 2 and is connected to the first conductive part 5, wherein the second conductive part 6 is a flat structure.

[0030] In the technical solution of the utility model, through the design of the insulating shell 1, the insulating shell 1 can provide reliable insulation performance, effectively prevent the current transmission and electromagnetic interaction between the inductor and adjacent components, reduce the risk of potential circuit failure and performance degradation, and the insulating shell 1 can provide physical protection for the magnetic core 3 and the coil 4 inside the inductor to avoid damage such as collision, extrusion, friction, etc. from the outside during installation, use or transportation, thereby extending the service life and reliability of the inductor;

[0033] In the embodiment of the utility model, a concave clearance groove 8 is further provided along the bottom end of the insulating shell 1 , and the clearance groove 8 is connected to the accommodating groove 2 , so that the lead wire 7 of the coil 4 is connected to the first conductive part 5 through the clearance groove 8 .

[0034] The give way groove 8 can provide a special channel for the lead wire 7 of the coil 4, so that the lead wire 7 can be connected to the first conductive part 5 more neatly and orderly, avoiding line confusion and crossing, and improving the regularity and aesthetics of the wiring; at the same time, it can effectively reduce the exposed part of the lead wire 7 and reduce the risk of external damage, such as scratches, extrusion, etc., thereby enhancing the durability and reliability of the lead wire 7 and not affecting the flatness of the patch.

[0035] In the embodiment of the utility model, the receiving groove 2 is opened at the central position of the bottom end of the insulating shell 1, and the bottom end of the shell and the peripheral side of the receiving groove 2 form the giving groove 8.

[0036] The accommodating groove 2 is in the center, and the circumferential side forms a relief groove 8. This layout can more effectively utilize the bottom space of the insulating housing 1, making the structure more compact and further leaving more peripheral space for other components.

[0037] In the embodiment of the present invention, the first conductive portion 5 is cylindrical.

[0038] Compared with other shapes, the cylindrical shape can provide a larger contact area when connected to the lead wire 7 of the coil 4, thereby reducing contact resistance, improving conductivity, and facilitating the welding work of the operator, thereby improving production efficiency.

This method can provide better positioning and stability; or the magnetic core 3 and the coil 4 can be bonded to the inner wall of the shell with glue or adhesive. Selecting a suitable adhesive can ensure the firmness and insulation of the connection.

[0045] By designing the positioning structure, the magnetic core 3 and the coil 4 can be effectively fixed in position in the accommodating groove 2, reducing displacement caused by factors such as vibration, impact or temperature change during use, thereby improving the stability and reliability of the overall structure of the inductor.

[0046] In the embodiment of the utility model, the magnetic core 3 is interference fit with the receiving groove 2 .
