Abstract
The utility model discloses a surface-mounted type common-mode filter inductor comprising a magnetic ring (1), wherein a varnished wire (2) is wound on the magnetic ring (1); a surface-mounted base (4) is arranged on the bottom of the magnetic ring (1) on which the varnished wire (2) is wound; the magnetic ring (1) on which the varnished wire (2) is wound is bonded with the surface-mounted base (4) by using an adhesive (3); an electrode (5) is arranged on the surface-mounted base (4); and the electrode (5) is respectively connected with outgoing lines on the magnetic ring (1). The varnished wire is wound on the magnetic ring, the outgoing end of the varnished wire is welded on the outgoing end of the surface-mounted base, and then, the magnetic ring on which a coil is wound is fixed on the surface-mounted base by using an acrylic acid pre-polymer, so that the magnetic ring common-mode filter inductor has the characteristic of heavy current and a surface mounting function.
Description
Technical field
The utility model relates to surface-mount type common mode filtering inductor, belongs to the inductors technique field.
Background technology
The common mode filtering inductor has the various electronic equipment power source common-mode signals of elimination, prevents that silicon controlled rectifier (SCR), three terminal bidirectional alternating-current switch (TRIAC) from producing noise, eliminates the effects such as power supply conversion tip voltage.Having conventional common mode filtering inductor way now is, direct coiling enamelled wire is wound on the direct scolding tin of line exit on the magnet ring on magnet ring, and product becomes inserter structure.But along with the rise of Surface Mount technology, various electronic electric equipment products are increasing to the demand of Surface Mount electronic devices and components, and the chip type of power inductance is more and more ripe, and existing common mode filtering inductor can not meet the demands.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of a kind of surface-mount type common mode filtering inductor that possesses simultaneously the large electric current characteristics of magnet ring common mode filtering inductor and have the Surface Mount installation function, to satisfy the electronic electric equipment product to the demand of Surface Mount electronic devices and components.
The technical solution of the utility model: surface-mount type common mode filtering inductor, it comprises magnet ring, is wound with enamelled wire on the magnet ring, is provided with the Surface Mount base in the bottom of the magnet ring that is wound with enamelled wire, the magnet ring and the Surface Mount base that are wound with enamelled wire are bonding with solid; Be provided with electrode at the Surface Mount base, electrode respectively with magnet ring on lead-out wire link together.
Described solid is acrylic polymer.
The Surface Mount base has the surface mount function.
Described magnet ring is ferrocart core magnet ring, manganese-zinc magnetic ring, amorphous magnet ring.
Compared with prior art: the utility model is the coiling enamelled wire on magnet ring, and the enamelled wire exit is welded on the exit of Surface Mount base, the magnet ring that will be wound with coil with acrylic polymer again is fixed on the Surface Mount base, so that the magnet ring common-mode inductor is also had a Surface Mount installation function when having large electric current characteristics.
