Description

Increased inductance and current inductance under height restrictions

This creation is an inductor, especially an inductor that increases the sense and current under height restrictions.

Common inductors can be used as chokes, windings, high and low frequency signal filters or transformer power conversions. Therefore, an inductor is disclosed. Referring to the first figure, there is a magnetic body assembly 10 and a substantially inverted U-shaped conductive plate 15. The magnetic assembly 10 includes a first magnetic body 11 and a set. a second magnetic body 12 above the first magnetic body 11, and the magnetic body assembly 10 is provided with a receiving groove 13 at the junction of the first magnetic body 11 and the second magnetic body 12 for the conductive The first magnetic body 11 is provided with a terminal receiving groove 14 at the bottom of the first magnetic body 11. The two ends of the conductive plate 15 are respectively bent inward to form a terminal portion 16 for use as an inductor. The terminal electrode of the conductive plate 15 is buried and latched against the terminal receiving groove 14 to form an inductor.

In this technical solution, in order to improve the characteristics of the inductor, such as the sense value and the current value, the inductor is usually designed to have a high height (for example, the entire magnetic component 10), or is designed to have a long length, thereby achieving better characteristics of the inductor. . However, in modern electronic products, designing too high or too long inductance is contrary to the direction of its design (except for the specific power capacity of the transformer), otherwise it should move toward volume reduction (especially height, height is too high) Will affect the thickness of the product) Inductors assembled by Surface-mount technology (SMT).

Therefore, how to provide inductance that can improve the sense and current under the height limit is the technical difficulty point that the applicant of the case wants to solve.

In view of the lack of practice, the purpose of this creation is to develop an inductor that increases the length of the magnetic (coupling) path under height constraints.

In order to achieve the above object, the present invention provides an inductor capable of improving the sense value and current under a height limitation, comprising: a conductor formed in a bent shape, and the conductor is provided with a plurality of bent portions, and the two ends of the conductor are respectively a first pin and a second pin are disposed; a first core is provided with a first joint surface, the first joint surface forms a groove for receiving the conductor; and a second core is a second bonding surface is disposed, the second bonding surface is coupled to the first bonding surface; wherein the conductor is disposed between the first magnetic core and the second magnetic core and the first pin is exposed And the second pin.

The first pin and the second pin respectively extend a first support portion and a second support portion, and the first support portion and the second support portion are symmetrically disposed.

Therefore, the creation of the magnetic (coupling) path length can be increased under the height limitation, and the effect of improving the sense value and current can be produced. In addition, the creation of the stilts can be made in a high-profile manner, so that additional space can be left on the circuit substrate under the inductor, so that other electronic components can be accommodated under the creative inductor, thereby saving the circuit substrate. The circuit layout space is reduced, and the use area of the circuit substrate is reduced to achieve the effect.

In order for your review board to have a clear understanding of the content of this work, please refer to the following examples with diagrams and symbols, please refer to it.

Referring to the second and third figures, the present invention provides an inductance that increases the sense and current under a height limitation, and includes: a conductor 2, a first core 3, and a second core 4.

The conductor 2 is formed in a bent shape, and the conductor 2 is provided with a plurality of bent portions 21, and the bent portions 21 can extend infinitely, not limited to the drawings, and the first ends of the conductors 2 are respectively provided with a first pin. 22 and a second pin 23. The first magnetic core 3 is provided with a first bonding surface 31. The first bonding surface 31 defines a recess 32 for receiving the conductor 2. In this embodiment, according to the bending shape of the conductor 2, a first forming surface 31 is formed. A plurality of cylinders 100 are not limited thereto.

The second core 4 is provided with a second bonding surface 41. The second bonding surface 41 is coupled to the first bonding surface 31. The conductor 2 is overlaid on the first magnetic core 3 and the second magnetic core. The first pin 22 and the second pin 23 are disposed between the cores 4 and exposed. In this embodiment, the bonding between the conductor 2, the first core 3 and the second core 4 is followed by an adhesive, which may be a thermosetting adhesive, a thermoplastic adhesive, Silicone adhesive, etc., and is not limited thereto.

Therefore, please continue to refer to the third figure, where 俾 can make the creation under the height limit of 200, increasing the magnetic (coupling) path length by 300, meaning that the inductance is extended from the horizontal direction, and According to the principle of inductive energy storage, the cross-sectional area of the creation becomes larger, which produces an effect of improving the sense value and current, which is superior to the prior art and is a feature of the creation.

Further, please refer to the fourth and fifth figures, wherein in addition to the height limit 200, the magnetic (coupling) path length 300 is increased, which can improve the sense value and the current value. In this embodiment, A main structure is similar to the same inductor, and the main difference is that the first pin 22 and the second pin 23 respectively extend a first support portion 5 and a second support portion 6. The first support portion 5 The second support portion 6 is symmetrically arranged, so that the design can be stepped on the high-pitched design, so that additional space can be left on the circuit substrate under the inductor, so that other electrons can be accommodated under the creative inductor. Components (such as integrated circuit ICs) can further save the circuit layout space of the circuit board, and reduce the use area of the circuit board to achieve the effect.
