Description

A kind of inductance facilitating production

Technical field

The utility model relates to electronic components, and in particular to inductance.

Background technique

Traditional heavy-current inductor, coil are wound on magnetic core using regular copper lines, but since operating current is larger, generally Between 30A to 40A, even more greatly, generally requires thicker copper wire and carry out coiling, but excessively thick copper wire winding is difficult, and And be difficult to control in terms of foot span, it is time-consuming and laborious in terms of whole foot.

Utility model content

Technical problem to be solved in the utility model is just to provide a kind of heavy-current inductor for facilitating production.

In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of inductance facilitating production, including The coil of magnetic core and copper wire winding, the magnetic core have closed-loop, and the coil is made of flat copper wire, and the coil is inserted Enter in closed-loop.

Preferably, the coil directlys adopt the flat copper wire of U-shaped structure.

Preferably, the coil is by multi-turn flat copper wire coiling ovalisation or circular configuration.

Preferably, the magnetic core is formed by two the first magnetic cores of separate structure and the second core combination.

Preferably, first magnetic core is U-shaped magnetic core, and second magnetic core is I type magnetic core, and I type magnetic core closes U-shaped magnetic core Opening to form the closed-loop.

Preferably, first magnetic core and the second magnetic core are U-shaped magnetic core, and the oral area docking of two U-shaped magnetic cores is to shape At the closed-loop.

Preferably, first magnetic core and the second magnetic core are combined using adhesive tape.

Preferably, the circle or ellipsoidal structure that the magnetic core is integrated.

Preferably, the coil and magnetic core are fixed together by glue.

The technical solution adopted in the utility model has the advantages that：

1, it directlys adopt in the insertion magnetic core closed-loop of coil made of flat copper wire, coil uses the preparatory coiling of flat copper wire It forms, high degree of automation, design simplifies wire winding in this way, and the assembling of coil and magnetic core is simple.

2, the coil made of flat copper wire coiling, not only coil tightness is good, and parasitic capacitance is small, and EMC effect It is good.

3, the coil made of flat copper wire coiling, so that the area-volume ratio of product increases, than regular copper lines coil More easily radiate.

4, minimum with size D.C. resistance using flat copper wire coiling, it is ensured that the resistance to current inductance value range of decrease is smooth and bears Instantaneous large-current ability is good.

Detailed description of the invention

The utility model is further described with reference to the accompanying drawings and detailed description：

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of the first magnetic core；

Fig. 3 is the structural schematic diagram of the second magnetic core；

Fig. 4 is the flat copper wire structural schematic diagram of U-shaped structure.

Specific embodiment

It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to this is practical Novel and its application or any restrictions used.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, is fallen within the protection scope of the utility model.

Embodiment one, as shown in Figure 1, a kind of heavy-current inductor for facilitating production, operating current is greater than 30A, generally in 30A To between 40A comprising the coil 2 of magnetic core 1 and copper wire winding, the magnetic core 1 have closed-loop, and the coil 2 is using flat Flat copper wire is made, and the coil 2 is inserted into closed-loop, and the coil 2 is fixed together with magnetic core 1 by glue, or can also With viscous and fixed by adhesive tape.Firstly, coil 2 is formed using the preparatory coiling of flat copper wire, high degree of automation；Secondly, flat Coil 2 made of copper wire is inserted into magnetic core closed-loop, is not necessarily to the coiling on magnetic core 1, and assembling is simple, facilitates production.

Refering to what is shown in Fig. 4, the flat copper wire of U-shaped structure can be directly used in the coil 2, the trouble of coiling is saved, into One step simplifies manufacture craft.

Shown in referring to figs. 1 to Fig. 3, in the present embodiment, the magnetic core 1 is by separate structure the first magnetic core 11 and the second magnetic core 12 are composed.First magnetic core 11 is U-shaped magnetic core, and second magnetic core 12 is I type magnetic core, and I type magnetic core closes U-shaped magnetic core Opening to form the closed-loop.First magnetic core 11 and the second magnetic core 12 can be combined together using adhesive tape.

As the deformation of above-described embodiment, the magnetic core 1 or integral structure, such as be integrated round or ellipse The structure of circular configuration or other shapes.

It will be appreciated by those skilled in the art that being, coil 2 can also be formed using flat copper wire coiling, such as coil is by more Enclose the flat copper wire coiling ovalisation perhaps structure of circular configuration or other shapes.

Certainly, the structure of the first magnetic core 11 and the second magnetic core 12 can make variation.For example, the first magnetic core 11 and the second magnetic Core 12 is U-shaped magnetic core, and the oral area docking of two U-shaped magnetic cores is to form the closed-loop.

To sum up, the utility model manufacture craft is convenient, saves many costs of labor, can be with automated production.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to attached drawing and specific embodiment party above Content described in formula.The modification of any function and structure principle without departing from the utility model is intended to be included in claims Range in.
