Problems solved by technology

[0004] Usually, high-current planar inductors are assembled with a single multi-layer circuit board, or a single spiral flat copper coil, or multiple flat copper sheets, with a fixed number of turns, low compatibility, simple assembly process, but different current levels. high
Due to the limitations of the laminated structure of the multilayer circuit board, a single spiral flat copper coil has a helical inclination, and the interlayer connection of multiple flat copper sheets accounts for too much, which makes it impossible to achieve multi-specification and high-current
A planar inductor with a composite structure can reach a high current level above 50A, but the composite structure leads to high assembly difficulty requirements, long assembly time, low yield and consistency

Abstract

The invention relates to the technical field of inductors, in particular to a high-current-carrying planar inductor and a manufacturing method thereof.The high-current-carrying planar inductor comprises a first bottom plate, lower mounting plates are arranged on the surface of the top end of the first bottom plate, adjusting mechanisms are arranged at the bottom ends of the lower mounting plates and used for adjusting the distance between the two lower mounting plates, and each adjusting mechanism comprises a sliding rod and a sliding piece; and the sliding rod is elastically connected with the sliding sheet through a spring. According to the assembling process of the planar inductor of the composite structure, the assembling difficulty can be reduced, the assembling efficiency can be improved, and the assembling yield and consistency can be improved.

Description

technical field [0001] The invention relates to the technical field of inductors, in particular to a high current-carrying planar inductor and a manufacturing method thereof. Background technique [0002] Inductors are a common electronic component. With the rapid development of the electronic information industry, inductors are used more frequently in the electronic information field, so the development of inductors is relatively rapid. [0003] For example, the authorized announcement number is CN107768069A, which discloses an inductor and its manufacturing method. On the basis of obtaining a large inductance inductor, it has a relatively high self-resonance frequency. Therefore, the existing inductors basically meet the needs of people, but still There are some problems. [0004] Usually, high-current planar inductors are assembled with a single multi-layer circuit board, or a single spiral flat copper coil, or multiple flat copper sheets, with a fixed number of turns, l...
