Description

Technical Field

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

[0002] Coil Inductor, also known as inductor or coil, is a component used to store magnetic energy in a circuit. It is made of wire wound one by one on an insulating tube, and these wires are insulated from each other during the winding process. The insulating tube can be hollow or contain an iron core or a magnetic powder core. When current passes through the coil, it generates a magnetic field around the inductor, which stores magnetic energy. When current passes through the coil, it generates a magnetic field around it. If the current changes, then the magnetic field will also change, which will generate an induced electromotive force in the wire. This induced electromotive force will oppose the change of current. Inductors have many applications in circuits.

[0003] For example, the Chinese authorized patent "A Coil Inductor" with announcement number CN215680364U includes a box body, a cylinder is fixedly installed on the bottom wall of the box body, a base is fixedly installed on the upper end of the cylinder, a cylinder is sleeved on the outside of the cylinder, a coil is fixedly installed on the outer wall of the cylinder, a pair of connecting wires are fixedly installed at the upper and lower ends of the coil, a fixing mechanism is installed in the cylinder, an iron core is inserted in the base, an end cover is provided at the upper end of the box body, a clamping mechanism is installed on the end cover, and a first circular groove and a second circular groove are respectively opened inside the upper ends of the two side walls of the box body.

[0004] Although the above-mentioned prior art can realize the disassembly and assembly of the coil inductor, the disassembly and assembly structure is relatively complicated and inconvenient to operate. In addition, when the inductor is working, the coil and magnetic material inside it will be affected by thermal stress. Long-term high-temperature operation may cause material aging and performance degradation. At the same time, the heat generated by the inductor will convert electrical energy into heat energy, resulting in a decrease in circuit efficiency. Heat may also increase the noise inside the circuit and affect the stability of the circuit. Therefore, it does not meet the existing needs. In this regard, we propose a coil inductor. Utility Model Content

[0005] The utility model aims to provide a coil inductor to solve the problems of inconvenient assembly and disassembly of the coil inductor and high heat generation during operation proposed in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a coil inductor, comprising a mounting plate, a fixing seat is arranged above the mounting plate, a magnetic core is installed inside the fixing seat, and both ends of the magnetic core are fixed to the fixing seat, and a winding group is wound around the outside of the magnetic core; and further comprising:

[0007] A semiconductor electronic refrigeration sheet is arranged inside the fixing seat, and the edge of the semiconductor electronic refrigeration sheet is snap-connected with the fixing seat, and a cooling plate is arranged on the upper end surface of the semiconductor electronic refrigeration sheet;

[0008] A limiting slide groove is arranged at the front and rear of both sides of the mounting plate, a support block is installed inside the limiting slide groove, and the support block and the limiting slide groove are slidably limited, a threaded hole is arranged inside the support block, a rotating rod is arranged at the front and rear of both sides of the mounting plate, a stud is arranged at one end of the rotating rod, one end of the stud is fixed to the rotating rod, and the other end of the stud extends to the inside of the support block, and the stud is matched with the threaded hole through a thread.

[0009] Preferably, the winding assembly comprises a coil, the outside of the coil is coated with a primer layer, the outside of the primer layer is coated with a functional layer, and the outside of the functional layer is coated with a protective layer.

[0010] Preferably, a heat dissipation channel is provided at the bottom of the fixing seat, a heat dissipation plate is installed inside the heat dissipation channel, and the heat dissipation plate is fixed to the bottom of the semiconductor electronic refrigeration sheet, and heat dissipation fans are fixedly installed on both sides of the bottom of the heat dissipation plate.

[0011] Preferably, the outer wall of the rotating rod is provided with annularly distributed protrusions, and the protrusions are higher than the upper end surface of the mounting plate.

[0012] Preferably, both ends of the winding group are provided with ends.

[0013] Preferably, a rubber pad is provided on the outer side of the support block, and the rubber pad is adhered and fixed to the support block.

[0014] Preferably, the heat dissipation channel runs through the front and rear of the fixing seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model installs a semiconductor electronic cooling sheet inside a fixing seat. When a direct current passes through a thermocouple pair composed of two different conductive materials, heat transfer is generated at the connection of the materials, so that one end absorbs heat and the other end releases heat. The cold end absorbs the heat generated by the inductor through the cooling sheet, while the hot end discharges the heat to the surrounding environment through the heat dissipation structure. In this way, the semiconductor cooling sheet can effectively reduce the temperature of the coil inductor and reduce the influence of thermal stress on the material, thereby extending the service life of the inductor and improving the efficiency and stability of the circuit.

[0017] 2. The utility model provides support blocks at the front and back of the mounting plate. Under normal circumstances, the support blocks are located inside the limiting slide groove, so that the mounting plate can be inserted and limited corresponding to the mounting groove. After the positioning is completed, the staff can push the upper end of the rotating rod to drive it to rotate, thereby driving the stud to rotate. One end of the stud is located in the inner screw hole of the support block, and thread friction occurs therewith. With the guiding effect of the limiting slide groove on the support block, the support block is gradually extended toward the outside of the limiting slide groove. On the one hand, the support block can be inserted and matched with the slot on the side wall of the mounting groove, thereby limiting the inductor at this position. On the other hand, if the side wall of the mounting groove is not provided with a slot, the support block directly contacts the inner wall of the mounting groove. As the extrusion force continues to increase, the inductor is fixed at this position. This structure is not only convenient to operate, but also can effectively improve the fixing effect of the inductor.

[0018] 3. The utility model provides a composite coating consisting of a base coating, a functional layer and a protective layer on the outside of the coil. The conductive material in the functional layer can optimize the circuit response time of the inductor coil and improve the accuracy and stability of the inductor. The thermal resistance material can effectively reduce the heat generated by the inductor during operation and prevent overheating, thereby extending the service life of the inductor. The electromagnetic shielding material can weaken the electromagnetic radiation inside the inductor coil, reduce interference with surrounding electronic devices, and improve the stability of the entire electronic system. The wear resistance and corrosion resistance of the outer protective layer can significantly improve the durability of the inductor coil, so that it can maintain stable operation in various harsh environments.

The stud 14 and the threaded hole 13 are matched through threads.

[0028] During use, under normal circumstances, the support block 6 is located inside the limiting slide groove 12, so that the mounting plate 1 can be inserted and limited to the corresponding mounting groove. After the positioning is completed, the staff can push the upper end of the rotating rod 5 to drive it to rotate, thereby driving the stud 14 to rotate. One end of the stud 14 is located in the inner screw hole of the support block 6, and thread friction occurs therewith.

On the other hand, if the side wall of the mounting groove is not provided with a slot, the support block 6 directly contacts the inner wall of the mounting groove.

The functional layer 16 can contain a variety of functional materials, conductive materials to improve inductance and stability, thermal resistance materials to optimize heat dissipation performance, and electromagnetic shielding materials to reduce electromagnetic interference. These materials can be mixed together to form a functional layer 16 with comprehensive performance.
