A Combined Anti-interference Magnetic Core

Abstract

The invention discloses a combined type anti-interference magnetic core which comprises two single magnetic core bodies. Each single magnetic core body comprises a magnetic core body and a magnetic cylinder integrally formed on the magnetic core body. Each magnetic core body comprises an integrally-formed base and three side walls forming a semi-enclosure structure with the base. The magnetic cylinders are arranged on the bases, and winding gaps are reserved between the magnetic cylinders and the three side walls. Each magnetic cylinder is equal to the corresponding three side walls in height. The magnetic cylinders are correspondingly provided with connecting columns and connecting structures connecting the two single magnetic core bodies. The connecting columns after being dismantled can be contained in the connecting structures. The combined type anti-interference magnetic core has the advantages of being capable of being used individually or in a combined mode, wider in application range and ingenious in design; more coils can be wounded around the magnetic cylinders, and therefore the product performance is more excellent; moreover, due to the unique structure, the magnetic core has the good anti-interference performance, and high-frequency interference is effectively restrained; the research shows that the anti-interference performance of the magnetic core can be further improved due to grooves formed in the magnetic cylinders in the length direction.

Description

technical field [0001] The invention relates to a magnetic core, in particular to a combined anti-interference magnetic core. Background technique [0002] The magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures, which is widely used in various magnetic devices such as transformers, high-frequency magnetic amplifiers, and filter choke coils. With the development of the electronics industry, the traditional single magnetic core can no longer fully meet the market demand. If multiple magnetic cores can be used in combination, the volume of the magnetic core can be increased to make it applicable to a wider range, but how to ensure The anti-interference performance of the combined magnetic core is a difficult problem in the industry. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an anti-interference magnetic core that can be used alone or in...
