Abstract
The utility model relates to the technical field of electronic devices, and particularly relates to a common mode inductor. The common mode inductor provided by the utility model comprises oppositely parallel magnetic cores, wherein a first coil and a second coil are arranged between the magnetic cores, a first input pin, a second input pin, a first output pin and a second output pin are oppositely arranged on the upper ends of the magnetic cores, and the central axis of the first coil and the central axis of the second coil are perpendicular to the magnetic cores; the first input pin, the second input pin, the first output pin and the second output pin are respectively perpendicular to the central axis of the first coil and the central axis of the second coil; and each winding of the first coil and the second coil comprises multiple separator plates. According to the common mode inductor, height of product can be reduced, and the occupied longitudinal space is reduced, so that installation of product is facilitated.
Description
Technical field
The utility model relates to technical field of electronic components, refers in particular to a kind of common mode inductance.
Background technology
A kind of small-sized common mode inductance of now domestic production, adopt the noise of high frequency to suppress countermeasure, the common mode choke coil structure, signal is unattenuated, volume is little, easy to use, have the advantages such as the degree of balance is good, easy to use, high-quality, be widely used in two balance tuning devices, multifrequency transformer, impedance transformer, balance and uneven conversion transformer etc.
Certainly, existing common mode inductance also has the certain deficiency on the project organization, and it is not too reasonable with the Position Design of, coil, pin mainly to be magnetic core, so that common mode inductance takies larger space, installs and has certain inconvenience.
Therefore, based on the defective of above-mentioned existing common mode inductance, need to improve existing common mode inductance.
The utility model content
The purpose of this utility model is to provide a kind of common mode inductance for the deficiencies in the prior art, and it is existing that this common mode inductance has solved existing common mode inductance: the Position Design of magnetic core and, coil, pin not too rationally, common mode inductance takies larger space, the defective such as inconvenience is installed.
For achieving the above object, the utility model is achieved through the following technical solutions:
Common mode inductance, the magnetic core that comprises opposing parallel, be provided with first, second coil between the magnetic core, magnetic core upper end is relative arranges the first input pin, the second input pin, the first output pin, the second output pin, and the axis of first, second coil is perpendicular to magnetic core.
Described the first input pin, the second input pin, the first output pin, the second output pin are respectively perpendicular to the axis of first, second coil.
Each winding of described first, second coil has a plurality of dividing plates.
The beneficial effects of the utility model are: can reduce the height of product, shared height space reduces, thereby is convenient to the installation of product.
