Abstract
The utility model discloses a common mode choke. The common mode choke comprises a magnet ring, a pair of coils, and a fixing part, wherein two bulges protruding outside the surface of the magnet ring is integrally formed on the magnet ring, the pair of coils is wound on the magnet ring, and the pair of coils is arranged on two sides of a connection line of the two protrusions, and therefore time of winding the coils is saved and the common mode choke is convenient to use. In addition, due to the facts that the magnet ring and the pair of coils are both installed on a shell body, and the fixing part is connected with the shell body in clamped mode, resistance and inductance value of the common mode choke is improved.
Description
Technical field
The utility model relates to the inductors technique field, relates in particular to a kind of common mode inductance.
Background technology
Existing common mode inductance twines one section enamelled wire at its magnet ring usually, but this can reduce impedance and the inductance value of common mode inductance.
Summary of the invention
In order to overcome defects, the utility model provides a kind of common mode inductance, and this common mode inductance has high impedance and high inductance.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of common mode inductance, comprise magnet ring, a pair of coil and fixture, be formed with two projections that protrude from the magnet ring surface at described magnet ring, this all is wrapped on the described magnet ring coil, and this lays respectively at the both sides of this two protruding line to coil, described magnet ring is installed on the housing coil jointly with this in addition, and described fixture buckle is connected on the described housing.
As further improvement of the utility model, this is wrapped in respectively the two ends of described housing to the lead terminal of coil.
As further improvement of the utility model, this two projection is symmetricly set on the inner surface of described magnet ring.
As further improvement of the utility model, this to the equal winding of single layer of coil on described magnet ring.
The beneficial effects of the utility model are: the utility model is connected with a fixture by buckle on the housing of magnet ring, has improved impedance and the inductance value of common mode inductance; Be formed with two projections that protrude from the magnet ring surface and be convenient to this is separated coil at magnet ring in addition, thereby the time of having saved winding around is easy to use.
