Description

Inductors that can increase inductance and current under height restrictions

technical field

In this technical solution, in order to improve the characteristics of the inductor such as the inductance value and the current value, the inductor is usually designed to have a higher height (for example, the magnetic component 10 as a whole), or to design a longer length to achieve better characteristics of the inductor. . However, in modern electronic products, designing an inductance that is too high or too long is against the direction of its design (except that the transformer needs a specific power capacity), otherwise it should move towards size reduction (especially the height, if the height is too high, the It will affect the thickness of the product), and it is common to use inductors for surface mount technology (Surface-mount technology, SMT).

Therefore, how to provide an inductor that can increase the inductance and current under the height limit is the technical difficulty that the applicant of this case wants to solve.

Utility model content

In view of the existing deficiencies, the purpose of this utility model is to develop an inductor that increases the length of the magnetic (coupling) path under height constraints.

In order to achieve the above objectives, the utility model provides an inductor that can increase the inductance value and current under the height limit, which includes: a conductor formed in a bent shape, and a plurality of bent parts are arranged on the conductor, and the two ends of the conductor A first pin and a second pin are respectively provided; a first magnetic core is provided with a first joint surface, and a groove for accommodating the conductor is formed on the first joint surface; a second magnetic core is provided with There is a second joint surface, the second joint surface is combined with the first joint surface; wherein the conductor is covered between the first magnetic core and the second magnetic core and the first pin and the second magnetic core are exposed. Second pin.

Wherein the first pin and the second pin are respectively extended with a first support portion and a second support portion, and the first support portion and the second support portion are arranged symmetrically.

Therefore, the utility model can increase the length of the magnetic (coupling) path under the height limit, and produce the effect of increasing the inductance value and the current. In addition, the utility model can also be designed to be elevated by walking on stilts, so that extra space can be vacated on the circuit substrate under the inductor of the utility model, so that other electronic components can be accommodated under the inductor of the utility model, which can save The circuit layout (layout) space of the circuit substrate reduces the use area of the circuit substrate to achieve the effect.
