Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application discloses an inductance device, and the inductance device can be applied to various illumination lamp products such as a barrel-shaped spotlight, a bulb and the like, an illumination module, a ceiling lamp, a street lamp, an industrial and mining lamp and the like, and in addition, the inductance device can also be applied to products in other electronic fields. The lamp product generally comprises a lamp body, a light source module and a driving module, wherein the light source module and the driving module are both arranged on the lamp body and are electrically connected with each other, the light source module is used for emitting illumination light, the driving module is used for driving the light source module, the driving module comprises a circuit board, and the inductance device is arranged on the circuit board. As shown in fig. 1 to 7, the inductance device includes an inductance skeleton 1, a winding 2, a first magnetic core 4 and a second magnetic core 5, and in some embodiments, the inductance device may further include an auxiliary coil 3.

The inductance framework in this embodiment may be made of an insulating material, and in order to reduce the cost, phenolic plastic is recommended as the material of the inductance framework 1. Specifically, as shown in fig. 2, 3, 4, 6 and 7, the bobbin 1 includes a main winding portion 10, and at least one winding slot 100 is disposed in the main winding portion 10. For a common inductive device, one winding slot 100 is typically provided inside the main winding portion 10, while for a common mode inductive device, two or more winding slots 100 may be provided inside the main winding portion 10. One winding 2 is correspondingly wound in each winding slot 100.

The winding slot 100 in the related art is generally a single slot, and a conductive wire with an insulating sheath, such as a flat wire, an enameled wire, a multi-strand wire, a triple-layer wire, or a covered wire, is spirally wound from an initial end to another end in the single slot, and then spirally wound from the other end to the initial end, and so on, to form a winding 2 having a multilayer structure from inside to outside in the single slot.

If the potential difference a between two adjacent turns (two turns) of wires is considered to be substantially equal, in such a winding 2 structure, the average potential difference b between two adjacent layers of wires is equivalent to the number m of turns of each layer of wires multiplied by the potential difference a, i.e., b ═ ma. And b is bigger, parasitic capacitance between two adjacent layers of wires is also bigger, and overlarge parasitic capacitance can generate high-frequency noise to influence the product performance.

In order to reduce the parasitic capacitance in this embodiment, each winding slot 100 is divided into at least two winding regions 100a as shown in the figure, and a wire passing channel 101a is disposed between the two winding regions 100 a. When winding the winding 2, a coil 20 is first wound and formed in one of the winding areas 100a, and the winding manner of the coil 20 is the same as that of the winding 2, i.e., the coil is wound from the initial end to the other end in a spiral manner, and then returns, and the coils are wound and stacked layer by layer. After the coil 20 is wound to the required number of layers, winding is completed, and then the end of the wire is guided into another adjacent winding area 100a from the wire passing channel 101a to continue winding to form a new coil 20, and the process is repeated in this way until all the winding areas 100a are wound to form the coil 20, and then the outlet end is led out, and winding of one winding 2 is completed. Wherein a section of the conductive wire passing through the wire passage 101a and connecting the adjacent two coils 20 can be referred to as a wire connection section 21.

Compared with the winding adopting the single-slot winding in the related art, in the case that the number of turns and the number of layers of the winding 2 of the inductance framework 1 adopting the embodiment are the same, the winding 2 in the embodiment is divided into the plurality of coils 20 connected in series in sequence, and the number of turns of the single-layer wire of each coil 20 is only a fraction of that of the related art, so that the average potential difference b between two adjacent layers of wires in the coil 20 is correspondingly reduced, and the parasitic capacitance possessed by the coil 20 is smaller.

Moreover, since the coils 20 are sequentially connected in series, the parasitic capacitance of the coils 20 is also sequentially connected in series, and the value of the capacitance after the series connection is smaller than the value of the parasitic capacitance with the minimum parasitic capacitance in the coils 20, so that the parasitic capacitance of the winding 2 formed in this embodiment is greatly reduced compared with the related art, thereby effectively reducing high-frequency noise and improving product performance.

The two adjacent winding regions 100a may be formed by relatively independent structures, or a plurality of partition plates 101 may be disposed in one large winding slot 100 to partition the winding slot 100 into a plurality of winding regions 100a, and the two adjacent winding regions 100a are partitioned by the partition plates 101, in which case the wire passing passage 101a may be a wire passing slot disposed on the partition plate 101. Although the through-hole type of wire passage provided in the partition plate 101 can also be used for the wire connection section 21, this structure requires that the wires are sequentially passed through the through-holes from the head, which is troublesome. The wire-passing gap can enable the wiring section 21 to directly slide into the gap from one end of the gap, and the operation is very simple and convenient.

When two or more winding slots 100 are simultaneously formed in the main winding portion 10 of the bobbin 1 in the present embodiment, two adjacent winding slots 100 may be insulated and isolated by the isolating plate 102. The partition plate 102 has substantially the same shape as the partition plate 101 except that the partition plate 102 does not need to have the wire passage 101 a.

To simplify the design, the main winding part 10 in this embodiment may have one main winding leg 103, and all the winding slots 100 are arranged along the axis of this main winding leg 103 and around the main winding leg 103. At the same time, the winding sections 100a in each winding slot 100 are also arranged along the axis of the main winding leg 103 and around the main winding leg 103.

More specifically, as shown in fig. 3, 4 and 7, the main winding portion 10 in the present embodiment further includes a first end plate 104 and a second end plate 105, the main winding pillar 103 is located between the first end plate 104 and the second end plate 105, edges of the first end plate 104 and the second end plate 105 extend beyond the main winding pillar 103 and together with the main winding pillar 103 form an integral winding slot, and the winding slot 100 is formed by at least a portion of the winding slot. When the main winding portion 10 is provided with a plurality of winding slots 100, all the winding slots 100 constitute a complete winding slot. When only one winding slot 100 is provided in the main winding portion 10, the winding slot 100 is a winding slot.

Both the divider plate 101 and the divider plate 102 may be fixedly connected to the main winding post 103 to directly divide the area of the main winding post 103. The main winding post 103 may have various applicable shapes such as a cylindrical shape, a square cylindrical shape, etc., and is not limited in this embodiment.

Inductance devices in the related art usually penetrate through a Printed Circuit Board (PCB) through a direct-insert pin and then are connected with the PCB in a welding mode, however, with the large-scale application of a high-efficiency chip mounting process, components adopting a direct-insert pin structure are gradually eliminated due to the fact that the direct-insert pin structure cannot be applied to the chip mounting process.

In order to make the inductor apparatus in this embodiment suitable for the chip mounting process, the inductor bobbin 1 further includes an auxiliary winding portion 11. The auxiliary winding portion 11 is connected to a bottom of the main winding portion 10 and protrudes from the main winding portion 10 in a horizontal direction.

The downward side of the auxiliary winding portion 11 is a welding surface 110, the auxiliary winding portion 11 is used for winding the auxiliary coil 3, and the wound auxiliary coil 3 is formed to cover at least a part of the welding surface 110 for welding. The auxiliary winding portion 11 in the present embodiment may have any of various structures suitable for winding the auxiliary coil 3, such as a square, a rectangular parallelepiped, a cylindrical body, a prism, and a prism. Meanwhile, the shape of the auxiliary coil 3 in the present embodiment is also not particularly limited as long as it can cover a part of the soldering face 110. For example, in the case of the square or rectangular auxiliary winding portion 11 shown in fig. 3 and 4, the auxiliary coil 3 may be annularly wound between two

vertical surfaces

111 and 112 adjacent to the welding surface 110 and an upward side surface 113 of the auxiliary winding portion 11, may be wound between the

vertical surfaces

111 and 112 and a side surface 114 of the auxiliary winding portion 11 away from the main winding portion 10, and may also be wound in other more complicated manners, which will not be described herein again.

In order to prevent the auxiliary coil 3 from being separated from the auxiliary winding portion 11, a stopper structure 115 may be provided on the auxiliary winding portion 11, and the auxiliary coil 3 may be restrained by the stopper structure 115, thereby preventing the auxiliary coil 3 from being separated from the auxiliary stopper portion 11. In this embodiment, the position-limiting structure 115 may be disposed on any surface of the auxiliary winding portion 11, and since the auxiliary coil 3 is a whole, the purpose of preventing the auxiliary coil 3 from being separated from the auxiliary position-limiting portion 11 can be achieved as long as any position of the auxiliary coil 3 can be prevented from being separated from the auxiliary position-limiting portion 11. However, in order to ensure the soldering effect, it is preferable to place the soldering surface 110 as close to the PCB as possible when the inductance device is assembled, and therefore, the position limiting structure 115 in this embodiment is preferably disposed on the other surface of the auxiliary winding portion 11 than the soldering surface 110.

In this example, the limiting structure 115 may be a limiting block, a limiting baffle, etc., wherein a form of a limiting groove is recommended. A part of the auxiliary coil 3 can be received by the stopper groove 115 (for convenience of description, reference numerals of the stopper structure are used hereinafter) so that the part cannot be separated from the auxiliary winding portion 11. The extending direction of the limiting groove 115 may be the same as or perpendicular to the extending direction of the main winding post 103, and may even be inclined relatively. The number of the limiting grooves 115 may be more than one, for example, one limiting groove 115 may be respectively disposed on the

vertical surfaces

111 and 112, or one limiting groove 115 extending in the same direction as the main winding post 103 may be disposed on the vertical surface 111, and a limiting groove 115 extending in a direction perpendicular to the axis of the main winding post 103 may be disposed on the surface 114, and the limiting grooves 115 may cooperate to limit the position. In addition, a plurality of segments of the limiting grooves 115 may be formed on the same surface, which is not illustrated here.

In this embodiment, when winding the winding 2 and the auxiliary coil 3, the winding 2 and the auxiliary coil 3 may be sequentially wound by the same enameled wire or other conducting wires with insulating sheaths, so that the winding 2 and the auxiliary coil 3 formed by winding are electrically connected, and the winding 2 may be directly powered by the auxiliary coil 3. In addition, the winding 2 and the auxiliary coil 3 in the present embodiment may be formed by winding different wires having insulating sheaths. At this time, there is no electrical connection between the auxiliary coil 3 and the winding 2, and the auxiliary coil 3 is only used for welding and fixing.

Since the windings 2 require at least one input and one output, each winding 2 is usually formed by winding the same enameled wire with two auxiliary coils 3. The two auxiliary coils 3 can be used as input and output terminals of the winding 2, respectively. Of course, the number of the input terminals and the output terminals of the winding 2 may be changed to cope with different application environments, and in this case, the number of the auxiliary coils 3 electrically connected to the winding 2 may be further increased.

When the inductance device is assembled on the PCB, the inductance device can be directly attached to the surface of the PCB, each auxiliary coil 3 on the inductance device is aligned to a corresponding welding pad on the PCB, then the metal wire inside the auxiliary coil 3 is exposed by melting the paint coating on the part, covering the welding surface 110, of the auxiliary coil 3 at high temperature, the metal wire can be melted and flows onto the welding pad on the PCB under the action of high temperature, and the auxiliary coil 3 and the welding pad can be welded after cooling and solidification.

In order to improve the stability of the assembly, the auxiliary winding portion 11 may be formed to extend on both sides of the main winding portion 10 in symmetry, and the auxiliary coil 3 may be wound on the auxiliary winding portion 11 on each side. Therefore, both sides of the inductance device can be connected with the PCB in a welding mode through the auxiliary coil 3 during welding operation, and stability is high. The number of the auxiliary winding parts 11 and the auxiliary coils 3 may be adjusted according to the required structural strength and the electrical connection requirement. Generally, the number of the auxiliary winding portions 11 is between 2 and 5.

In the present embodiment, each auxiliary coil 3 is usually wound on one auxiliary winding portion 11 individually. However, the present embodiment does not exclude the auxiliary coils 3 being wound around the plurality of auxiliary winding portions 11 located on the same side of the main winding portion 10 at the same time. For example, the auxiliary coil 3 may be formed by winding an enameled wire around two auxiliary winding portions 11 located on the same side as two supporting points to form one elongated auxiliary coil 3. The auxiliary coil 3 has a larger welding area with the PCB, so that the structure stability and the electrical stability are more excellent. Of course, the middle portion of the auxiliary coil 3 may include other auxiliary winding portions 11 to support the middle portion thereof in addition to the two auxiliary winding portions 11 as fulcrums when being wound, and thus the same auxiliary coil 3 may be simultaneously wound on two or more auxiliary winding portions 11.

Besides, the enamel wire may be led from the surface 113 of one auxiliary winding portion 11 to the surface 113 of another auxiliary winding portion 11, or from the welding surface 110 of one auxiliary winding portion 11 to the welding surface 110 of another auxiliary winding portion 11, or from the surface 113/welding surface 110 of one auxiliary winding portion 11 to the welding surface 110/surface 113 of another auxiliary winding portion 11, thereby forming a monoclinic or crossed structure. In addition to the above-described structure, in some embodiments, the enamel wire may be wound around the auxiliary winding portion 11 by lengthening the auxiliary winding portion 11 to form the elongated auxiliary coil 3.

For the common mode inductance, two windings 2 are usually provided, and therefore, a solution in which 4 auxiliary winding portions 11 are provided symmetrically in pairs is preferably adopted. The input end and the output end of each winding 2 are respectively wound on the two auxiliary winding parts 11 arranged on the same side to form two auxiliary coils 3.

In this embodiment, the inductive device may be a vertical inductive device or a horizontal inductive device, as shown in fig. 1 to 4, in the vertical inductive device, the axis of the main winding post 103 is perpendicular to the horizontal plane, the first end plate 104 is located at the bottom of the main winding post 103, and the second end plate 105 is located at the top of the main winding post 103. All the auxiliary winding portions 11 at this time are connected to the side surface of the first end plate 104. Since all the windings 2 in the vertical inductor are sequentially arranged in a direction perpendicular to the horizontal plane, the input end and the output end of the windings 2 need to be led out to the auxiliary winding portion 11 in the vertical direction to wind the auxiliary coil 3.

In order to facilitate the winding 2 above to be led out to the auxiliary winding portion 11 and to limit the position of the lead wire not to be moved randomly to cause wire disconnection, the partition plate 101 and the partition plate 102 may be provided with a wire-passing limiting portion 106 corresponding to the auxiliary winding portion 11. In the present embodiment, the wire-passing stopper 106 is generally disposed near the upper side of the auxiliary winding portion 11, and may be directly above or obliquely above. The wire-passing limiting portions 106 corresponding to the same auxiliary wire-winding portion 11 and having different heights may form vertical channels or inclined channels.

The heights led out from the input end and the output end of each winding 2 may be different, and the number of the wire-passing limiting portions 106 corresponding to each auxiliary winding portion 11 may be set on the inductance skeleton 1 according to a winding manner designed in advance, but this may result in poor universality of the inductance skeleton 1 and low winding efficiency. Therefore, the inductance skeleton 1 in the present embodiment may be provided with the corresponding wire-passing limiting portion 106 on each of the partition plate 101 and the partition plate 102 corresponding to each of the auxiliary winding portions 11, so that the inductance skeleton 1 can be adapted to whatever winding form is adopted.

In this embodiment, the inductive device may also be a horizontal inductive device, as shown in fig. 5 to 7, in which the axis of the main winding post 103 is parallel to the horizontal plane, and the first end plate 104 is located on one side of the main winding post 103, and the second end plate 105 is located on the other side of the main winding post 103. In this case, a portion of the auxiliary winding portion 11 is connected to a lower side of the first end plate 104, and another portion of the auxiliary winding portion 11 is connected to a lower side of the second end plate 105. Since all the windings 2 in the horizontal inductor are sequentially arranged in the horizontal direction, and the auxiliary winding portions 11 are respectively disposed on the first end plate 104 and the second end plate 105, the input end and the output end of the windings 2 need to be led out to the respective auxiliary winding portions 11 along the axial direction of the main winding post 103 to wind the auxiliary coil 3.

In order to facilitate the winding 2 to be led out to the auxiliary winding portion 11 and to limit the position of the lead wire from moving randomly to cause wire disconnection, in this embodiment, the partition plate 101, the first end plate 104 and the second end plate 105 may be provided with wire-passing limiting portions 106 corresponding to the auxiliary winding portion 11. In the present embodiment, the wire-passing limiting portion 106 is generally horizontally disposed or slightly inclined with respect to the corresponding auxiliary wire-winding portion 11. Each of the wire-passing stoppers 106 corresponding to the same auxiliary winding portion 11 may form a horizontal passage or a relatively inclined passage. Also, the wire-passing stopper 106 is preferably provided at a side surface of the main wire winding part 10, not at a bottom surface, to prevent a short circuit risk caused by contact with a PCB board at the time of soldering.

Similarly, the number of the wire-passing limiting portions 106 corresponding to each auxiliary winding portion 11 may be set on the bobbin 1 according to a winding manner designed in advance, but this may result in poor versatility of the bobbin 1 and low winding efficiency. Therefore, the inductance framework 1 in this embodiment may be provided with corresponding wire-passing limiting portions 106 on the first end plate 104 or the second end plate 105 connected to each auxiliary winding portion 11 and on the corresponding partition plate 101, so that the inductance framework 1 can adapt to any winding form.

In this embodiment, the wire-passing limiting portion 106 may be a limiting notch, regardless of whether the vertical inductor device or the horizontal inductor device is used. The limiting notch is simple in structure, convenient to form and good in wire clamping effect.

As shown in fig. 1 to 7, in the present embodiment, the first magnetic core 4 is buckled on the first end plate 104, the second magnetic core 5 is buckled on the second end plate 105, and the first magnetic core 4 and the second magnetic core 5 form a closed magnetic field. In the present embodiment, the main winding leg 103 may be provided with a through insertion hole 103a, the first end plate 104 may be provided with a first fitting portion 104a for fitting the first magnetic core 4, the second end plate 105 may be provided with a second fitting portion 105a for fitting the second magnetic core, and the insertion hole 103a may communicate the first fitting portion 104a and the second fitting portion 105 a.

When the first core 4 is fitted into the first fitting portion 104a, and a part of the first core 4 is inserted into the insertion hole 103a, for example, the first core 4 has an E-shape, and the central extension of the E-shape is the central post 40, so that the central post 40 is inserted into the insertion hole 103 a. Meanwhile, a part of the second core 5 is inserted into the second fitting portion 105a, and a part of the second core 5 also extends into the insertion hole 103a, for example, the second core 5 may have an E-shape, and the central post 50 extends into the insertion hole 103a when the central post 50 extends from the middle of the E-shape. The first magnetic core 4 and the second magnetic core 5 have extensions on both sides thereof covering the periphery of the winding 2.

In this embodiment, in order to further adapt the inductor device to the chip mounting process, an adsorption plane may be further formed on the upper surface of the inductor device. For a vertical inductive device, the surface of the second magnetic core 5 can be used as a suction plane. For the horizontal type inductance device with the axis of the main winding post 103 parallel to the horizontal plane, most of the upper surface area is the winding 2, which is not flat enough, so that the adsorption structure 6 can be separately arranged in the inductance device, and the adsorption structure 6 can cover the winding slot 100 from above and can be detachably connected with the first magnetic core 4 and/or the second magnetic core 5 through clamping, magnetic connection and the like. Adsorption structure can provide the absorption plane up, makes the whole sucking disc that can be adsorbed by the suction cup and snatchs.
