[0038] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0040] like Figure 1 As shown, the rod-shaped inductor structure in the related art has only two diagonal pins soldered on the PCB board, which will swing left and right during vibration. In the case of high vibration and long endurance time, fatigue fracture problems may occur in the PIN pins of the rod-shaped inductor, such as Figure 2 As shown in the figure, the PIN pin breakage failure occurred in the board-level test of the 40G sinusoidal rod inductor.

[0041] like Figure 3 As shown, the utility model provides a rod-shaped inductor structure 100, which includes a base 10, an inductor body 11 and a second pin 12. The inductor body 11 is accommodated in the base 10, and the inductor body 11 has two first pins 111. The second pin 12 is connected to the base 10. The second pin 12 and the two first pins 111 are both used to connect to a circuit board.

[0042] It is worth noting that the rod-shaped inductor structure 100 can increase the number of pins connected to the circuit board, reduce the risk of pin breakage failure, and improve the connection stiffness between the rod-shaped inductor and the circuit board, thereby improving its overall first-order mode and enduring more fatigue times.

[0043] like Figure 3 and Figure 4 As shown, the inductor body 11 includes a magnetic rod 112 and an enameled wire 113 . The enameled wire 113 is spirally wound around the magnetic rod 112 , and two ends of the enameled wire 113 are respectively connected to first pins 111 , and the two first pins 111 are diagonally arranged.

[0044] It is worth noting that the two diagonally arranged first pins 111 can reduce the mutual influence between the inductors, thereby improving the stability and performance of the entire circuit. At the same time, the two diagonally arranged first pins 111 are also the rod-shaped inductor structure 100 in the related art, which can reduce production costs and help simplify layout and connection.

[0045] like Figure 5 and Figure 7As shown, the base 10 has a receiving groove 101, and the rod-shaped inductor structure 100 also includes a mounting bracket 13, the mounting bracket 13 has a guide hole 131 and a winding hole 132, the enameled wire 113 is passed through the winding hole 132, the first pin 111 is passed through the guide hole 131, the magnetic rod 112 is mounted on the mounting bracket 13, the mounting bracket 13 and the receiving groove 101 are adapted to each other, and the mounting bracket 13 is embedded in the receiving groove 101.

[0046] It is worth noting that the introduction of the mounting bracket 13 can prevent the inductor body 11 from being directly mounted on the base 10. While being adapted to the base 10, the mounting bracket 13 can provide sufficient holding force for the inductor body 11, thereby reducing the deformation of the rod-shaped inductor structure 100 during use.

[0047] like Figure 6 and Figure 7 As shown, an adhesive is coated between the accommodating groove 101 and the mounting bracket 13, and / or between the mounting bracket 13 and the magnetic rod 112. In one implementation of this embodiment, the adhesive includes epoxy resin glue. It can be understood that epoxy resin glue has the advantages of strong bonding, high temperature resistance, and chemical corrosion resistance. At the same time, it has good electrical insulation properties and can be used in electronic devices, circuit boards and other occasions that require insulation protection. Using epoxy resin glue as an adhesive can increase the holding force between the inductor body 11 and the base 10, thereby improving the first-order mode of the rod-shaped inductor structure 100 and improving the stiffness of the overall structure.

[0048] Please refer again Figure 7 There are two mounting brackets 13 , and the two mounting brackets 13 are respectively embedded at the two ends of the receiving groove 101 , and the two ends of the magnetic bar 112 are respectively mounted on the two mounting brackets 13 .

[0049] It is worth noting that the use of two segmented mounting brackets 13 makes the installation process more flexible and adjustable, and its length or position can be adjusted as needed to accommodate inductor bodies 11 or accommodating slots 101 of different sizes or shapes. In addition, the segmented mounting bracket 13 is easier to install than a single long bracket. The installer can install it segment by segment instead of installing the entire long bracket at one time, thereby improving the installation efficiency. At the same time, the segmented mounting bracket 13 has better parts interchangeability, and a single part can be easily replaced or repaired without disassembling the entire bracket system.

[0050] In this embodiment, the bottom plane of the first pin 111 overlaps with the bottom plane of the second pin 12. It can be understood that the bottom plane of the first pin 111 overlaps with the bottom plane of the second pin 12, which can simplify the design, reduce costs, and improve reliability and maintainability.

[0051] like Figure 4 and Figure 7 As shown, the number of the second pins 12 is multiple. In this embodiment, the cross section of the base 10 is rectangular, the number of the second pins 12 is two, and the two second pins 12 and the two first pins 111 are respectively located at the four corners of the base 10. Depending on the specific implementation environment, the number of the second pins 12 can also be 3, 4, etc., and this embodiment does not constitute a limitation on the specific number and position thereof, as long as it can increase the structural strength of the rod-shaped inductor structure 100 when connected to the circuit board.

[0052] In addition, in this embodiment, the second pin 12 and the base 10 are integrally formed.

[0053] It is worth noting that the integrally formed base 10 and second pin 12 can increase the holding force between the rod-shaped inductor and the base 10. Figure 8 and Fig. 9 As shown, through simulation analysis, the first-order mode of the conventional rod-shaped inductor structure 100 in the related art is 732Hz, and the first-order mode of the rod-shaped inductor structure 100 provided in this embodiment is 1955Hz. Compared with the rod-shaped inductor structure 100 in the related art, the first-order mode of the rod-shaped inductor structure 100 of this embodiment is improved to meet higher vibration requirements. Vibration simulation analysis of conventional rod-shaped inductors and high-vibration resistant rod-shaped inductors is performed in response to the random vibration requirements of commercial vehicle transmission controllers. The high-vibration resistant rod-shaped inductor structure 100 has a smaller deformation and can withstand more fatigue times. The high-vibration resistant rod-shaped inductor structure 100 provides more selection and design guidance for the high vibration requirements of high electronic devices in commercial vehicle transmission controllers.

[0054] The embodiment of the utility model also provides a transmission controller, including the above-mentioned rod-shaped inductor structure, having all its beneficial effects.
