Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to a novel external structure of a chip inductor. Background Art

[0002] A chip inductor refers to an inductor used in surface mount technology. Its main function is to store energy in a circuit and provide a stable current. As electronic products develop towards miniaturization and integration, the design and manufacturing of components are constantly innovating. As an important passive component, the chip inductor plays an indispensable role in various electronic devices. With its characteristics of small size, light weight, and easy installation, the chip inductor is widely used in high-frequency circuits, filters, DC / DC converters and other fields, meeting the requirements of modern electronic products for high performance and high density.

[0003] In the existing inductor structure, relatively thick copper wires or copper foils are often used to replace the leads. When using relatively thick copper wires as the leads, it is often very difficult to make the leads flat, which easily leads to the problem of unstable lead connection during the inductor mounting stage, and it is difficult to control the lead pitch and position. Therefore, a large amount of manual labor hours will be consumed to straighten the leads. Moreover, when using copper foil to connect with the leads first to replace the leads, it will cause very troublesome operations when the inductor needs to be repaired.

[0004] In view of this, it is necessary to propose a new technical solution to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to provide a technical solution that can solve the above problems in order to overcome the above deficiencies.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A novel external structure of a chip inductor, including a skeleton, a coil is wound inside the skeleton, and leads are led out from the coil;

[0007] First fixing blocks and second fixing blocks are arranged on both sides of the lower end of the skeleton. Hanging feet are provided on both the first fixing block and the second fixing block, and the leads can be connected to the hanging feet;

[0008] Among them, the first fixing block and the second fixing block are respectively inserted and fixed on both sides of the skeleton.

[0009] As a further scheme of the utility model: A plurality of T-shaped insertion blocks are arranged on the sides of the first fixing block and the second fixing block away from the hanging feet. T-shaped insertion grooves corresponding to the T-shaped insertion blocks are opened on both sides of the skeleton, and the T-shaped insertion blocks are tightly inserted and fixed with the T-shaped insertion grooves.

[0010] As a further scheme of the utility model: The hanging feet are in an "L" shape, and a plurality of the hanging feet are respectively fixed to the first fixing block and the second fixing block.

[0011] As a further solution of the present utility model: the hanging foot with an "L" - shaped structure includes a vertical part and a horizontal part, wherein the outgoing lead is wound around the vertical part.

[0012] As a further solution of the present utility model: both the first fixing block and the second fixing block are provided with a relief notch for the outgoing lead to pass through.

[0013] As a further solution of the present utility model: the edge of the T - shaped socket groove facing the external space has an inclined chamfer.

[0014] Compared with the prior art, the beneficial effects of the present technical solution are as follows:

[0015] 1. By using the hanging feet of the first fixing block and the second fixing block to connect with the outgoing leads of the coil, the outgoing leads can be replaced by the hanging feet. When performing the surface - mounting of the inductor and the PCB board, the hanging feet can provide stable support for the inductor, and at the same time, can be more firmly connected to the welding points of the PCB, solving the problem that the direct outgoing of the existing thick copper wire leads to an insecure connection with the PCB board.

[0016] Moreover, the first fixing block and the second fixing block are fixed with hanging feet, and the pitch between several hanging feet is fixed. Therefore, there is no need to spend labor to arrange the outgoing copper wires, and contact between the outgoing leads can be avoided.

[0017] 2. Furthermore, during the inductor assembly process, both the first fixing block and the second fixing block are tightly fitted into the T - shaped socket groove from both sides of the skeleton through the T - shaped plug blocks, so that the T - shaped plug blocks are inserted and fixed with the T - shaped socket groove. Then, the outgoing leads are connected to the hanging feet, thus quickly completing the inductor assembly. When the inductor needs to be repaired, the first fixing block and the second fixing block can be pulled outwards to separate the T - shaped plug blocks from the T - shaped socket groove, facilitating the repair work of the inductor, and solving the problem of troublesome repair when using copper sheets to replace the outgoing leads in the prior art.

[0018] 3. By setting the hanging feet in an "L" - shaped structure and using the vertical part of the hanging feet to facilitate the winding of the outgoing leads, the connection between the outgoing leads and the hanging feet is convenient and fast. When performing the surface - mounting of the inductor, the bottom surface of the horizontal part of the hanging feet is flat, improving the stability of the inductor when placed on the PCB board and avoiding the movement and offset of the inductor during the welding with the PCB board.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-3 A novel chip inductor structure includes a frame 1, a coil 2 wound inside the frame 1, and a lead 21 extending from the coil 2;

[0028] Preferably, a first fixing block 3 and a second fixing block 4 are provided on both sides of the lower end of the frame 1, and hanging feet 5 are provided on the first fixing block 3 and the second fixing block 4, and the protruding feet 21 can be connected to the hanging feet 5;

[0029] The first fixing block 3 and the second fixing block 4 are respectively plugged and fixed to the two sides of the frame 1;

[0030] Several T-shaped plug-in blocks 6 are set on the side of the first fixing block 3 and the second fixing block 4 away from the hanging foot 5, and T-shaped plug-in grooves 11 corresponding to the T-shaped plug-in blocks 6 are opened on both sides of the skeleton 1, and the T-shaped plug-in blocks 6 are tightly plugged and fixed with the T-shaped plug-in grooves 11.

[0031] Specifically, by setting the first fixing block 3 and the second fixing block 4, and connecting the hanging foot 5 with the lead-out foot 21 of the coil 2, the hanging foot 5 can replace the lead-out foot 21. When performing the patch mounting of the inductor and the PCB board, the hanging foot 5 can provide stable support for the inductor, and at the same time, it can be more firmly connected to the welding point of the PCB, solving the problem that the direct lead-out of the existing thick copper wire leads to an insecure connection with the PCB board;

[0032] Moreover, the first fixing block 3 and the second fixing block 4 are fixed with the hanging foot 5, and the pitch between several hanging feet 5 is fixed. Therefore, there is no need to spend labor to sort out the copper wire lead-out feet, and contact between the lead-out feet 21 can be avoided;

[0033] Furthermore, during the inductor assembly process, both the first fixing block 3 and the second fixing block 4 are inserted and fitted into the T-shaped insertion slot 11 from both sides of the skeleton 1 through the T-shaped insertion block 6, and after insertion, the T-shaped insertion block 6 and the T-shaped insertion slot 11 are closely fitted, so that the T-shaped insertion block 6 and the T-shaped insertion slot 11 are inserted and fixed. Then, the lead-out foot 21 and the hanging foot 5 are connected, thus quickly completing the inductor assembly. When the inductor needs to be repaired, the first fixing block 3 and the second fixing block 4 can be pulled outwards manually to separate the T-shaped insertion block 6 from the T-shaped insertion slot 11, facilitating the repair work of the inductor and solving the problem of troublesome repair when using copper sheets to replace the lead-out foot 21 in the prior art;

[0034] Among them, the skeleton 1, the first fixing block 3, the second fixing block 4, and the T-shaped insertion block 6 are all made of plastic materials with good heat resistance. Utilizing the toughness of the plastic material itself, after the T-shaped insertion block 6 is inserted and fitted with the T-shaped insertion slot 11, it can maintain good stability and avoid falling off easily. At the same time, it can also be insulated from the coil 2.

[0035] Preferably, the hanging foot 5 has an "L" - shaped structure, and several hanging feet 5 are respectively fixedly connected to the first fixing block 3 and the second fixing block 4.

[0036] Preferably, the hanging foot 5 with an "L" - shaped structure includes a vertical part 51 and a horizontal part 52, and among them, the lead-out foot 21 is wound around the vertical part 51.

[0037] Specifically, when the inductor is assembled, by setting the hanging foot 5 to have an "L" - shaped structure and using the vertical part 51 of the hanging foot 5 to facilitate the winding of the lead-out foot 21, the connection between the lead-out foot 21 and the hanging foot 5 is convenient and fast. When performing the surface mounting of the inductor, the bottom surface of the horizontal part 52 of the hanging foot 5 is flat, improving the stability when the inductor is placed on the PCB board and avoiding the inductor from moving and shifting during welding with the PCB board.

[0038] Preferably, both the first fixing block 3 and the second fixing block 4 have a relief notch 7 for the lead-out foot 21 to pass through.

[0039] Specifically, when the pin 21 is led out from the coil 2 and connected to the hanging pin 5, the pin 21 can be passed through the clearance gap 7, and then the position of the pin 21 can be fixed by using the clearance gap 7. At the same time, it is also convenient to pass the pin 21 through the first fixing block 3 and the second fixing block 4.

[0040] Preferably, the edge of the T-shaped inserting slot 11 facing the external space has an inclined chamfer.

[0041] Specifically, the inclined chamfer can play a guiding role when the T-shaped plug-in block 6 is plugged into the T-shaped plug-in slot 11, making it easier to align the T-shaped plug-in block 6 and smoothly insert it into the T-shaped plug-in slot 11, thereby reducing the resistance when the T-shaped plug-in block 6 is inserted, making the assembly process of the first fixed block 3 and the second fixed block 4 smoother and more convenient.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
