Thin combined inductor structure and assembly method thereof

Abstract

The invention discloses a thin combined inductor structure and an assembly method thereof. The thin combined inductor structure comprises a core, a flat coil, a board and an upper cover; the flat coil which is hollow comprises two pin parts extending out; the upper surface of the board is used for holding the core and the flat coil; the upper cover connected with the board is used for covering the cover and the flat coil. In this way, after the core is mounted on the board, by the use of the flat coil allowing the core to be nested in, the core, the board and the upper cover, wherein the core, the board and the upper cover are separated, the problems that non-uniform winding is caused in the prior winding process, parts are difficult to separately manufactured, making use of magnetic materials different in magnetic characteristic is difficult and the shifting of wire ends cause failure of the wire ends to be passed out of hanging slots are avoided.

Description

technical field [0001] The present invention relates to an inductor structure and an assembly method thereof, in particular to a thin combined inductor structure with a flat coil in which a core can be sheathed, and an assembly method of the inductor structure. Background technique [0002] In the current field of electronic components, inductance elements are often used as passive elements in electronic circuits, and the function of the inductance element is usually as a filter for suppressing high-frequency signals in high-frequency circuits. figure 1 It is a structural diagram of a known inductance element, wherein the inductance element has a core 10 , a coil 11 , a base 12 , and a casing 13 . The core 10 is made of an I-shaped magnetic material, and has an upper core plate 101 , a lower core plate 102 , and a column 103 integrally formed. The core lower plate 102 is connected to the lower surface of the cylinder 103, and optionally has an outlet groove 1011 for the two...

Problems solved by technology

[0005] Furthermore, it is known that if the inductance element is in a skewed state after the shell 13 and the core 10 are assembled, a gap will be generated between the shell 13 and the outer edge, which will cause the divergence of the magnetic flux loop and the change of the inductance value.
