Abstract
The invention provides a filter and relates to electronic technical field. A filter comprises a coil holder 1, a coil 2, leading-out pins 6, a first magnetic core 3, and a second magnetic core 4. The coil 2 is wound around the coil holder 1. The first side of the first magnetic core 1 and the first side of the second magnetic core 4 are inserted into the coil 2 along a direction vertical to the leading-out pins 6 and are combined mutually. The second side of the first magnetic core 1 and the second side of the second magnetic core 4 are wound around the coil 2 and are mutually combined. The first magnetic core 3 and the second magnetic core 4 are connected with the coil holder 1 through epoxy glue 5. The first magnetic core 3 is connected with the second magnetic core 4 through epoxy glue 5. The filter is uneasy to loosen and has a stable inductance characteristic.
Description

Wherein, the first magnetic core 3, the second magnetic core 4 and coil holder 1, and by epoxy glue 5, interconnect between the first magnetic core 3 and the second magnetic core 4.
Preferably, the mesopore height of described coil holder 1 is 2.0～3.0mm.
Preferably, described the first magnetic core 3 and the second magnetic core 4 are wrapped up by metal around the limit of coil, for clamping the first magnetic core 3 and the second magnetic core 4.
Preferably, described coil holder 1 is double flute coil holder, and described coil 2 is twin coil.
(3) beneficial effect
The present invention is by a kind of filter is provided, and by magnetic core and coil holder and magnetic core and magnetic core junction, adopts epoxy glue as fixative, makes that filter is firm to be difficult for looseningly, and inductance characteristic is stable.
By reducing the height of coil holder mesopore, arrive preset range, make it possible to realize and Horizontal multi-shaft coil winding machine automatic winding coil, and then automated production in enormous quantities, significantly improved production efficiency.
