Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to an integrated inductor. Background Art

[0002] An inductor is an electronic component whose basic structure is a conductive coil, sometimes with a magnetic core inside, which is used to store energy and exhibit specific electrical characteristics in the circuit. The core functions of inductors are filtering, oscillation, delay, notch, signal screening, current stabilization, and electromagnetic interference suppression. The characteristics of inductors mainly include inductive reactance, energy storage, self-inductance, nonlinearity, Q value, etc. Inductors are widely used in power electronics, communication equipment, radio systems, switching power supplies, filter circuits and other fields.

[0003] With the development of miniaturization of electronic products, the size of small inductors has been reduced to the physical limit. It can be seen that the future development direction of inductors is integration. Inductors will be combined with other discrete devices into complex modules to provide users with a complete system that is easy to use. However, for now, miniaturized discrete devices are still the main ones, and there is still some distance to achieve integration.

[0004] Based on this, Chinese patent CN210606918U discloses an integrated inductor, which includes: a metal plate, a winding and a magnetic core. The winding is arranged on the metal plate, some pins of the winding are inserted into the metal plate, and the winding is electrically connected to the metal plate. The magnetic core includes a first magnetic core and a second magnetic core that are connected to form a closed magnetic circuit, the first magnetic core and the second magnetic core are arranged on the metal plate, and the winding is wound between the first magnetic core and the second magnetic core. The integrated inductor disclosed in this patent can electrically connect the winding through the metal plate, reduce the wiring on the PCB board, reduce the number of solder joints between the integrated inductor and the PCB board, facilitate installation, and the structure is convenient for automated production.

[0005] However, the integrated inductor disclosed above still has the technical problem of serious heat accumulation. Specifically, the main function of the inductor in the circuit is to filter, time, and be a two-terminal element for power electronics applications. It is a kind of energy storage element that can convert electrical energy into magnetic energy and store it. The inductor is usually composed of a coil and a magnetic core. When current flows through the coil, a magnetic field is generated around the coil. The magnetic field interacts with the change of the current to generate inductive reactance, which hinders the change of the current. The coil will generate resistance when current passes through, resulting in energy loss. This part of the lost energy will be converted into heat, causing the inductor to heat up. The integrated inductor disclosed in the existing patent is mainly to facilitate the automated assembly of the integrated inductor by first setting the winding on the metal plate and then installing the magnetic core; thus, the winding located on the corresponding metal plate will continue to accumulate heat, and because the metal plate is a structure installed close to the circuit board, the position where the metal plate is corresponding to the circuit board will have serious heat accumulation.

[0028] Please also read Figures 1 to 4 The utility model discloses an integrated inductor comprising: a skeleton body 1, a connection hole 2, a connection column 3, a layout groove 4, a coil 5, an insulating block 6, a padding structure 7 and a pin structure 8; a plurality of the connection holes 2 and a plurality of the connection columns 3 are respectively arranged on the two sides of the skeleton body 1; each of the connection holes 2 corresponds to a connection column 3; a plurality of the layout grooves 4 are arranged between the connection holes 2 and the connection columns 3, and a plurality of the layout grooves 4 are evenly distributed on the skeleton body 1; each of the layout grooves 4 corresponds to a sleeve of a coil 5, and an insulating block 6 is arranged between every two coils 5; a plurality of the padding structures 7 are evenly distributed at the bottom of the skeleton body 1, and a plurality of the pin structures 8 are evenly distributed and connected under the skeleton body 1.

[0029] Specifically, the skeleton body 1 provided in the integrated inductor of the utility model is made of insulating material, for example, plastic, rubber and the like. The two sides of the skeleton body 1 are respectively provided with a plurality of connection holes 2 and a plurality of connection pillars 3. The two adjacent skeleton bodies 1 can be connected to the connection holes 2 provided on the other side of the other skeleton body 1 by using the connection pillars 3 provided on one side of the skeleton body 1 to match and connect the connection holes 2 provided on the other side of the other skeleton body 1, so that the two skeleton bodies 1 are assembled to form an assembly body. By analogy, a plurality of skeleton bodies 1 can be connected in a row by connecting end to end to form an integrated whole. Thereafter, the integrated whole can be connected to an external circuit board or other assembly through the pin structure 8 provided at the bottom thereof. In addition, a plurality of layout grooves 4 are evenly provided in the skeleton body 1, and each layout groove 4 can be correspondingly sleeved with a coil 5, and the coil 5 can be made of a conductor material such as copper wire, and each two coils 5 are insulated and isolated by an insulating block 6, so as to form a magnetic induction structure of the inductor. Furthermore, the bottom of the skeleton body 1 is provided with the padding structure 7. When the pin structure 8 is connected to an external circuit board or other structure, the padding structure 7 is located between the skeleton body 1 and the circuit board or other structure. Firstly, the coil 5 can be raised to prevent the coil 5 from contacting an external conductor; secondly, the skeleton body 1 can be raised to form a sufficient air flow channel at the bottom of the skeleton body 1, thereby achieving a heat dissipation effect. Therefore, the utility model can prevent the occurrence of heat accumulation in the skeleton body 1 or the circuit board.

[0035] Furthermore, a ventilation slot 104 is provided at the bottom of the skeleton body 1; a plurality of ventilation slots 104 are evenly provided on the side of each layout slot 4, and each ventilation slot 104 is connected to the side of a corresponding coil 5. Specifically, the ventilation slot 104 is conducive to quickly guiding the heat out of the coil 5, thereby enhancing the heat dissipation effect.
