Problems solved by technology
[0004] At present, the standard horizontal filter products at home and abroad all use single-axis machines and single-wire winding coils, and the two slots cannot be automatically wound by multi-axis machines at the same time, and the efficiency is low; and the fixed magnetic core is the same as the wire frame. Fixed with insulating varnish, affected by environmental factors, the magnetic core is easy to loose, resulting in poor electrical properties

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
technical field [0001] The invention relates to the field of electronic technology, in particular to a filter. Background technique [0002] Filter is an electrical component that reduces or eliminates the influence of harmonics on the power system. Its function is to get a specific frequency or eliminate a specific frequency. [0003] Filter products include vertical filters and horizontal filters. [0004] At present, the standard horizontal filter products at home and abroad all use single-axis machines and single-wire winding coils, and the two slots cannot be automatically wound by multi-axis machines at the same time, and the efficiency is low; and the fixed magnetic core is the same as the wire frame. It is fixed with insulating varnish, and the magnetic core is easy to loose due to the influence of environmental factors, resulting in poor electrical properties. Contents of the invention [0005] (1) Solved technical problems [0006] Aiming at the deficiencies ...
