Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an inductor core structure. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only hinders the change of current.

[0003] Inductors are installed in electronic devices, mainly used to change the size and direction of current, and to adjust the frequency and impedance in the circuit.

[0004] However, the existing inductor core structure is an integral whole. When the number of winding turns on the inductor core needs to be increased, a different inductor core structure needs to be replaced to wind more turns. The existing inductor core structure cannot be adjusted in length as needed to adjust the number of winding turns.

[0005] When two coils need to be wound on the inductor core, a partition needs to be installed in the middle of the inductor core to separate them. The existing method is to install a partition in the middle of the inductor core by glue, which is troublesome and cumbersome. Utility Model Content

[0006] The purpose of the utility model is to provide an inductor core structure to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: an inductor core structure, comprising a bottom support plate and an extension column located at the top of the bottom support plate; the top of the bottom support plate is connected to the bottom of the column by welding, the extension column is provided at one end of the column away from the bottom support plate, the extension column is threadedly connected to the top of the column, the end of the extension column away from the column is connected to the top support plate by welding, the outer wall of the column is provided with a partition, and the partition is connected to the outer wall of the column by sliding.

[0008] Preferably, the outside of the column is connected to the winding in a winding form, and the winding and the joint are integrally formed.

[0009] Preferably, grooves are formed on both sides of the bottom support plate and the top support plate, and the joint is located inside the grooves.

[0010] Preferably, the interior of the partition is connected to the support column via a fastener, and one end of the support column away from the partition is connected to the telescopic column in an embedded manner.

[0011] Preferably, the outer wall of the column is provided with limiting grooves, the limiting grooves are distributed at equal intervals on the column, and one end of the telescopic column away from the supporting column is connected to the limiting groove in an embedded manner.

[0012] Preferably, one side of the telescopic column is connected to a push block via a fastener, and the push block is connected to the partition in a penetrating manner.

[0013] Preferably, the interior of the support column is connected to one end of the elastic member via a fastener, and the end of the elastic member away from the support column is connected to the telescopic column via a fastener.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model can adjust the length of the inductor core structure as needed by providing a column and an extension column so as to wind a winding with a suitable number of turns. When the length of the inductor core needs to be adjusted, the bottom support plate is held and then the top support plate is rotated. The rotation of the top support plate drives the extension column to move out of the interior of the column through the thread. The movement of the extension column drives the top support plate to move until the distance between the top support plate and the bottom support plate is suitable for the length of the winding to be wound, that is, the length of the inductor core is adjusted, which reflects the practicality of this device.

[0016] Secondly, the utility model can separate two different coils by providing a partition and an elastic member. Before winding the coil, the push block is moved, and the push block moves to drive the telescopic column to move to the inside of the support column. The telescopic column squeezes the elastic member so that one end of the telescopic column is no longer located in the limiting groove. Then the partition is moved to the middle position of the column, and the push block is released. Through the rebound force of the elastic member, the elastic member pushes one end of the telescopic column to enter the limiting groove again, and the partition is limited. The coil can be wound on both sides of the partition without the need to use glue for assembly. It is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] See also Figure 1-4 , an inductor core structure, comprising a bottom support disk 1 and an extension column 8 located at the top of the bottom support disk 1; the top of the bottom support disk 1 is connected to the bottom of the column 7 by welding, and the end of the column 7 away from the bottom support disk 1 is provided with an extension column 8, and the extension column 8 is threadedly connected to the top of the column 7, and the end of the extension column 8 away from the column 7 is connected to the top support disk 2 by welding, and the outer wall of the column 7 is provided with a partition 6, and the partition 6 is connected to the outer wall of the column 7 by sliding. When the length of the inductor core needs to be adjusted, the bottom support disk 1 is held, and then the top support disk 2 is rotated. The rotation of the top support disk 2 drives the extension column 8 to move out of the interior of the column 7 through the thread, and the movement of the extension column 8 drives the top support disk 2 to move until the distance between the top support disk 2 and the bottom support disk 1 is suitable for the length of the winding 3 to be wound, that is, the adjustment of the inductor core length is achieved, which reflects the practicality of this device.

[0024] Specifically, the outside of the column 7 is connected to the winding 3 in a winding manner, and the winding 3 and the joint 4 are formed as one piece.

[0025] Through the above technical solution, the inductor core is adjusted as needed before winding 3 is performed. After the winding 3 is wound on the column 7 and the extension column 8, it is inconvenient to adjust it.

[0026] Specifically, grooves 5 are formed on both sides of the bottom support plate 1 and the top support plate 2 , and the joint 4 is located inside the groove 5 .

[0027] Through the above technical solution, the groove 5 is used to guide the connector 4 of the inductor, so that the connector 4 can be easily connected to an external electronic device.

[0028] Specifically, the interior of the partition 6 is connected to the support column 11 through a fastener, and one end of the support column 11 away from the partition 6 is connected to the telescopic column 12 in an embedded manner.

[0029] Through the above technical solution, the support column 11 is used to limit and support the telescopic column 12 to prevent the telescopic column 12 from tilting or deflecting when it moves.

[0030] Specifically, the outer wall of the column 7 is provided with limiting grooves 9, which are distributed at equal intervals on the column 7, and one end of the telescopic column 12 away from the supporting column 11 is connected to the limiting grooves 9 in an embedded manner.

[0031] Through the above technical solution, a plurality of limiting grooves 9 are provided on the column 7. When the extension column 8 is moved, the partition 6 can be moved to different positions, so that when the inductor core becomes different lengths, the partition 6 can be located in the middle.

[0032] Specifically, one side of the telescopic column 12 is connected to the push block 10 through a fastener, and the push block 10 is connected to the partition plate 6 in a penetrating manner.

[0033] Through the above technical solution, the pushing block 10 is used to push the telescopic column 12 so that the telescopic column 12 is no longer located inside the limiting groove 9, which facilitates the adjustment of the position of the partition 6.

[0034] Specifically, one end of the elastic member 13 is connected to the inside of the support column 11 through a fastener, and the end of the elastic member 13 away from the support column 11 is connected to the telescopic column 12 through a fastener.

[0035] Through the above technical solution, the elastic member 13 is used to push the telescopic column 12 so that one end of the telescopic column 12 can always be located inside the limiting groove 9. The telescopic column 12 limits the partition 6 through the limiting groove 9 to prevent it from moving randomly after moving to the appropriate position.

[0036] When in use, first hold the bottom support plate 1 when the length of the inductor core needs to be adjusted, and then rotate the top support plate 2. The rotation of the top support plate 2 drives the extension column 8 to move out of the interior of the column 7 through the thread. The movement of the extension column 8 drives the top support plate 2 to move until the distance between the top support plate 2 and the bottom support plate 1 is suitable for the length of the winding 3 that needs to be wound. Move the push block 10, and the push block 10 moves to drive the telescopic column 12 to move to the interior of the support column 11. The telescopic column 12 squeezes the elastic member 13 so that one end of the telescopic column 12 is no longer located in the limiting groove 9. Then move the partition 6 to the middle position of the column 7, release the push block 10, and through the rebound force of the elastic member 13, the elastic member 13 pushes one end of the telescopic column 12 to enter the limiting groove 9 again, limit the partition 6, and the work is completed.
