Description

Technical Field

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

[0002] Electronic components are basic elements in electronic circuits, usually referring to devices with two or more leads or metal contacts in individual packages. They must be connected to each other to form electronic circuits with specific functions, such as amplifiers, radio receivers, oscillators, etc. Electronic components may be individual packages, such as resistors, capacitors, inductors, transistors, diodes, etc., or groups of varying complexity, such as integrated circuits, i.e. operational amplifiers, resistor arrays or logic gates.

[0003] Electronic components can be roughly divided into two categories: active components and passive components, based on their different roles in the circuit. Active components can amplify or control electrical signals and usually require an external power supply to work, such as transistors or integrated circuits. Passive components do not have amplification functions, and they mainly play the role of storing or consuming energy, such as resistors, capacitors, and inductors.

[0004] Inductors are an important category of passive components. They are also often called coils or chokes. They are electronic components that can store magnetic energy and convert electrical energy into magnetic energy. When current passes through an inductor, a magnetic field is generated around it; and this magnetic field can resist rapid changes in current. The basic function of an inductor is to achieve resistance to current changes in a circuit, which is expressed as inductance, with the unit being Henry.

[0005] Based on this, Chinese patent CN210403470U discloses an inductor resistant to high-voltage shock, which includes a winding frame, a coil and an inductor shell; the coil is wound on the winding frame using a honeycomb winding method to form a number of inductor wire packages, there are gaps between the inductor wire packages, and the connection between the inductor wire packages is in a tensioned state; the winding frame is a hollow structure, and a through hole for potting is set on the winding frame; the coil uses multiple strands of Litz wire; the inductor shell is provided with a fixing hole and an electrode lead-out hole; the winding frame and the inductor wire package are placed in the inductor shell; a frame fixing guide groove is set on the inner side of the inductor shell, and the two ends of the winding frame are placed in the frame fixing guide groove; the inside of the inductor shell is vacuum potted with epoxy resin potting glue or polyurethane resin potting glue. This kind of inductor solves the problem that the insulation problem is difficult to handle when using a magnetic core to meet the protection inductor requirements, and the magnetic core reaches a saturated state and cannot achieve the protection effect.

[0006] However, the above disclosed inductor that resists high-voltage shock still has technical problems that the inductance value is difficult to meet the demand and the assembly is inconvenient. Specifically, the structure of the inductor that resists high-voltage shock disclosed by the existing patent is coreless as a whole. The inductor without a core structure has the following advantages: there is no saturation in the design without a core. There is no need to consider the inductance saturation during the design calculation process. It is only necessary to calculate the peak current in the inductance according to the discharge voltage waveform, and select the appropriate protection inductance according to the peak current that can be tolerated; the coreless structure is more friendly in insulation treatment, and there is no need to specially design insulation for the core. Although the structural form of removing the core can simplify the insulation treatment of the core to a certain extent; however, the main function of the inductor core is to provide an environment with high magnetic permeability to enhance the magnetic flux of the coil, thereby increasing the inductance value of the inductor. The material of the core is usually a soft magnetic material, such as ferrite, nickel-zinc ferrite, manganese-zinc ferrite, etc. These materials have high magnetic permeability and low magnetic loss. The presence of the magnetic core enables the inductor to store more magnetic energy in a smaller volume, which is particularly important in high-frequency circuits; because, in high-frequency applications, the volume of the inductor is limited, and the magnetic core can help the inductor provide the required inductance value within a limited volume. Utility Model Content

[0028] Please also read Figure 1 to Figure 2 The utility model is an inductor that is easy to assemble, comprising: a skeleton structure 1, a winding structure 2, a magnetic core bar 3, a first stopper 4, a second stopper 5 and an elastic clamping block 6; the skeleton structure 1 has a main structure 101, a surrounding groove structure 102, an insulating isolation block 103 and a core cavity 104; a plurality of the surrounding groove structures 102 are evenly arranged on the side of the main structure 101, and an insulating isolation block 103 is arranged between every two surrounding groove structures 102; the core cavity 104 is arranged at the center of the main structure 101; a plurality of the winding structures 2 surround the core cavity 104 ... The winding is arranged on the side of the skeleton structure 1, and each of the winding structures 2 is correspondingly arranged in one of the surrounding groove structures 102; the magnetic core bar 3 is movably sleeved in the core cavity 104, and the first stop block 4 and the second stop block 5 are relatively connected to the two end sides of the skeleton structure 1, one end of the first stop block 4 and one end of the second stop block 5 respectively abut the two ends of the magnetic core bar 3, and the other end of the first stop block 4 and the other end of the second stop block 5 are connected to each other; the elastic clamping block 6 is respectively connected to the first stop block 4 and the second stop block 5.

[0029] Specifically, the skeleton structure 1 is made of insulating material, preferably PPS, i.e., polyphenylene sulfide. The PPS material has high mechanical strength, good heat resistance and chemical corrosion resistance, and excellent dimensional stability. Especially in high temperature, high pressure, and highly corrosive environments, the PPS material can ensure that the inductor works stably for a long time and is not prone to deformation or damage.

[0030] Specifically, the core cavity 104 is arranged at the center of the main structure 101, and a plurality of the surrounding slot structures 102 are arranged around the core cavity 104, and each of the slow-winding slot structures 102 is not connected, that is, it can be ensured that the winding structure 2 arranged in the surrounding slot structure 102 can ensure mutual insulation with the magnetic core bar 3 arranged in the core cavity 104; more specifically, the magnetic core bar 3 is accommodated in the core cavity 104, and the winding structure 2 is accommodated in the surrounding slot structure 102. The core cavity 104 and the surrounding slot structure 102 are physically separated by the insulating material of the main structure 101 itself, which can ensure the insulation performance and improve the impact resistance and high voltage resistance of the inductor; at the same time, the introduction of the magnetic core bar 3 also increases the upper limit of the inductance value of the inductor.

[0031] Furthermore, in order to ensure the insulation performance of the magnetic core bar 3, the two ends thereof are respectively connected to the first stopper 4 and the second stopper 5, and the first stopper 4 and the second stopper 5 are symmetrical L-shaped structures, and the first stopper 4 and the second stopper 5 can be made of the same material as the skeleton structure 1, that is, the first stopper 4 and the second stopper 5 can also be made of PPS material; thus, the first stopper 4 and the second stopper 5 are also insulating materials; after the two are connected, although they will be located on the adjacent side of the winding structure 2, due to their own insulation properties, they can also ensure the insulation performance of the inductor when it is working.

[0032] Specifically, the first stopper 4 and the second stopper 5 are connected as L-shaped structures respectively, and the advantages of not forming the two as a whole U-shaped structure are: the PPS material lacks elasticity, and if it is formed as a U-shaped structure, it is difficult to assemble with the skeleton structure 1 and the magnetic core bar 3. The utility model proposes a more optimal assembly scheme for an inductor that is easy to assemble, that is, the first stopper 4 and the second stopper 5 are respectively formed as two L-shaped structures into a U-shaped structure, and the two are clamped and connected by the elastic clamping block 6, so as to be fixed to the side of the skeleton structure 1; thereby, the assembly convenience between the components is improved.

[0033] Furthermore, the skeleton structure 1 is provided with a side slot structure 105; the side slot structure 105 is a T-shaped slot, and the two side slot structures 105 are relatively arranged at the two end sides of the main structure 101; the first stopper 4 or the second stopper 5 is correspondingly movably connected to one of the side slot structures 105. Specifically, the side slot structure 105 is preferably a T-shaped slot structure, and each of the side slot structures 105 can be provided with one of the first stopper 4 or one of the second stopper 5, so as to facilitate the fixed connection between the two. In addition, the shape of the T-shaped slot can also allow the first stopper 4 or the second stopper 5 to change the direction of connection, such as Figure 3 As shown, the two can be connected to the top or side of the main structure 104, so that the inductor can be easily adapted to different installation environments; and the first stopper 4 or the second stopper 5 can be prevented from interfering with the electronic components around the inductor.

[0034] Furthermore, the skeleton structure 1 is provided with side connection holes 106 and side connection pillars 107; a plurality of the side connection holes 106 are provided at one end side of the main structure 101, and a plurality of the side connection holes 106 are evenly distributed around the side slot structure 105, and the side connection pillars 107 are provided at the other end side of the main structure 101 relative to the side connection holes 106, and each side connection pillar 107 is provided corresponding to one side connection hole 106. Specifically, the provision of the side connection holes 106 and the side connection pillars 107 can facilitate the mutual matching connection of the two adjacent skeleton structures 1, and more specifically, in the two adjacent skeleton structures 1, the side connection holes 106 at the end side of one of the skeleton structures 1 can accommodate the side connection pillars 107 at the adjacent end side of the other skeleton structure 1, so that the two adjacent skeleton structures 1 can be assembled and connected; thereby forming an inductor product with more winding structures 2.

[0035] Furthermore, a pin structure 7 is provided below the skeleton structure 1, and a plurality of the pin structures 7 are evenly distributed and connected to the bottom of the main structure 101. Specifically, the pin structure 7 can be used to connect the inductor to external devices such as a circuit board.

[0036] Furthermore, each of the winding structures 2 can be wound with a flat copper wire, and before winding, the surface of the flat copper wire needs to be insulated.

[0037] Further, the elastic clamping block 6 has a U-shaped bending body 601, an end clamping portion 602 and an upper and lower clamping portion 603; each end of the U-shaped bending body 601 is provided with an end clamping portion 602, and each end clamping portion 602 is connected to the end of the first stopper 4 or the end of the second stopper 5. At least one upper and lower clamping portion 603 is arranged on the side of the U-shaped bending body 601, and the upper and lower clamping portions 603 are respectively connected to the first stopper 4 and the second stopper 5. Specifically, the end clamping portion 602 can clamp the end of the first stopper 4 or the second stopper 5, and the upper and lower clamping portions 603 can clamp the upper and lower sides of the first stopper 4 and the second stopper 5, respectively, so as to realize the clamping connection of the first stopper 4 and the second stopper 5. More specifically, the elastic clamping block 6 can be made of metal springs by connecting and bending, for example, the elastic clamping block 6 can be made of stainless steel, brass or phosphor bronze.

[0038] In summary, the utility model is an inductor that is easy to assemble, which is respectively provided with a skeleton structure 1, a winding structure 2, a magnetic core bar 3, a first stopper 4, a second stopper 5 and an elastic clamping block 6; the skeleton structure 1 has a main structure 101, a surrounding groove structure 102, an insulating isolation block 103 and a core cavity 104; a plurality of the surrounding groove structures 102 are evenly arranged on the side of the main structure 101, and an insulating isolation block 103 is arranged between every two surrounding groove structures 102; the core cavity 104 is arranged at the center of the main structure 101; a plurality of the winding structures 102 are arranged on the side of the main structure 101, and a plurality of the winding structures 102 are arranged on the side of the main structure 101; The structure 2 is arranged around the side of the skeleton structure 1, and each winding structure 2 is correspondingly arranged in one of the surrounding slot structures 102; the magnetic core bar 3 is movably sleeved in the core cavity 104, the first stopper 4 and the second stopper 5 are relatively connected to the two end sides of the skeleton structure 1, one end of the first stopper 4 and one end of the second stopper 5 respectively abut the two ends of the magnetic core bar 3, and the other end of the first stopper 4 and the other end of the second stopper 5 are connected to each other; the elastic clamping block 6 is respectively connected to the first stopper 4 and the second stopper 5. The magnetic core bar 3 is accommodated in the core cavity 104, and the winding structure 2 is accommodated in the surrounding slot structure 102. The core cavity 104 and the surrounding slot structure 102 are physically separated by the insulating material of the main structure 101 itself, so that the inductor can improve the impact resistance and high voltage resistance of the inductor under the premise of ensuring the insulation performance; at the same time, the introduction of the magnetic core bar 3 also increases the upper limit of the inductance value of the inductor. In addition, the utility model combines the two L-shaped structures of the first stopper 4 and the second stopper 5 into a U-shaped structure, and then clamps and connects the two using the elastic clamping block 6, so as to fix them to the side of the skeleton structure 1; thereby, the assembly convenience between the components is improved. Therefore, the utility model solves the technical problem of how to optimize the upper limit of the inductance value of the inductor that resists high-voltage impact and improve the assembly convenience of the inductor.

[0039] The technical features of the above-described embodiments may be arbitrarily combined.
