Description

Inductive component

The present invention relates to the technical field of manufacturing and structure of an inductor component, and more particularly to an inductor component.

Inductors have been developed to a wide range of applications, including communication systems, signal processing systems, filters, tank circuits, and the like, all requiring inductors for circuit purposes. As the times change, electronic systems are shrinking, and electronic components must be scaled down. Therefore, when inductors cannot be eliminated in circuit design, engineers are working to reduce the size of inductors, increase the withstand voltage and eliminate The probability of arc generation.

The inductive component is a passive component in an electronic circuit, and the basic component includes a magnetic core and a coil. In order to respond to different electronic circuits, different types of inductance components are designed. Different types of inductance components have different inductance properties, such as gapped inductor components and gapless inductor components have different characteristics. Compared with the inductive component with gap, the gapless inductor component has no gap on the ferromagnetic, which can make the inductor component have higher inductance value and smaller current, and the gap component can prevent the gap on the ferromagnetic. When a current flows through the inductive component, the inductive component enters a magnetic saturation state and cannot be used.

Please refer to FIG. 1 , which is a perspective view of a conventional inductive component. The conventional inductive component comprises a winding portion P11 and two flange portions P12, and each flange portion P12 has four enameled wire receiving portions P121. Thus, in the conventional inductive component manufacturing process, four enameled wires P2 are first wound around the same. The winding portion P11 is further provided on each of the enameled wire receiving portions P121 at both ends of each of the enameled wires P2.

Further, please refer to FIG. 1 and refer to FIG. 2 at the same time, which is a schematic diagram of a conventional inductive component coupled to a circuit board; as shown in the figure, in the application of the inductive component, it is necessary to The two enameled wire receiving portions P121 located in the middle are short-circuited. Therefore, when the conventional inductive component is disposed on the circuit board P3, the four enameled wire receiving portions P121 are electrically electrically connected to the first on the circuit board P3. The conductive sheet P31 and the second conductive sheet P32 are arranged such that the four enameled wires P2 are respectively short-circuited with each other.

However, in the conventional inductive component and its manufacturing process, since the two flange portions P12 are disposed at both ends of the winding portion P11, the number and length of windings of the enamel wire P2 are directly limited to the winding portion P11. The length, so, when it is desired to increase the inductance characteristics of the inductance component, it is usually completed by increasing the volume of the winding portion P11, but in this way, the volume of the overall inductance component is increased, so how is the inductance A balance between features and component volume often leads to a dilemma between manufacturers and designers.

In the above description, the conventional inductive component structure is respectively configured to receive the two ends of the enameled wire P2 through the four enameled wire receiving portions P121, and then pass through the second conductive sheet P32 on the circuit board P3. In the process of the circuit board P3, the second conductive sheet P32 is connected to the two enameled wire accommodating portions P121, so that the area thereof is relatively large, and thus, This leads to disadvantages such as increased manufacturing costs and waste of resources.

Referring to FIG. 4, since the primary side and the secondary side wire are respectively connected to the bottom solder joint via the two side wire grooves 126', when a plurality of inductors 1' are soldered side by side to the PCB circuit board 2' and When operating in a high-voltage environment (eg 2500V), the primary side conductor of the inductor 1' is easily air-discharged to the secondary side conductor of the adjacent inductor 1', affecting the withstand voltage of each inductor 1', to improve this problem. The distance between the individual inductors 1' must be pulled apart to reduce the discharge effect, but this method will affect the space utilization of the PCB board 2'.
