Problems solved by technology

[0002] Ferrite core is a high-frequency magnetic material, mainly for high-frequency transformers (such as switching power supplies, line output transformers, etc.), high-frequency magnetic rings (for anti-interference), etc., the existing double-layer combination The combined installation of ferrite cores is inconvenient to operate, and the fixation stability between the sector cores of the same layer of combined ferrite cores and between the upper and lower layers of combined ferrite cores is poor. For this reason, we propose A cross buckle fan-shaped seven-part double-layer combined ferrite core for radio frequency transformers and its manufacturing process to solve the problems mentioned in the above background technology

Abstract

The invention discloses a cross-buckle fan-shaped seven-part double-layer combined ferrite magnetic core for a radio frequency transformer. The combined ferrite magnetic core comprises an upper-layercombined ferrite magnetic core body, a lower-layer combined ferrite magnetic core body, an upper protective cylinder and a lower fixed seat, wherein the upper protective cylinder and the lower fixed seat are fixed at upper and lower ends of the two combined ferrite magnetic core bodies; the middle parts of the combined ferrite magnetic core bodies are fixedly connected through a connecting mechanism; the combined ferrite magnetic core body on the same layer is formed by combining seven groups of fan-shaped magnetic cores; winding grooves are formed in the bottoms of the fan-shaped magnetic cores; the winding grooves at the bottoms of the seven groups of fan-shaped magnetic cores form a circular ring groove for arranging a coil. According to the invention, the middle parts of the combined ferrite magnetic core bodies on the upper and lower layers are fixedly connected through the connecting mechanism, so the fan-shaped magnetic cores of the combined ferrite magnetic core bodies on the same layer are firmly combined, and the combined ferrite magnetic core bodies on the upper and lower layers are stably fixed.

Description

Technical field [0001] The invention belongs to the technical field of ferrite cores, and specifically relates to a cross-buckle sector-shaped seven-part double-layer combined ferrite core for radio frequency transformers and a manufacturing process thereof. Background technique [0002] Ferrite core is a high-frequency magnetic material, mainly used for high-frequency transformers (such as switching power supplies, line output transformers, etc.), high-frequency magnetic rings (for anti-interference), etc., the existing double-layer combination The combined installation of ferrite cores is not easy to operate, and the fixed stability between the sector cores of the same layer of combined ferrite cores and between the upper and lower layers of combined ferrite cores is poor. For this reason, we propose A cross-buckle sector-shaped seven-part double-layer combined ferrite magnetic core for a radio frequency transformer and a manufacturing process thereof are used to solve the prob...
