Coil component and method of producing the same

Abstract

The invention relates to a coil component and a method of producing the same. The coil component is provided with first and second wires that are wound around a winding core. The nth turns of the first and second wires are wound around a surface of the winding core in this order in parallel and form a first winding layer. Each of the n+1th and subsequent turns of the second wire is wound around the surface of the winding core so as to be parallel to a previous turn of the second wire and form the first winding layer. Each of the n+1th and subsequent turns of the first wire is wound on the first winding layer so as to be fitted into a valley of the first winding layer formed by the same and previous turns of the second wire and form a second winding layer. The same turns of the first and second wires are adjacent to each other at each turn.

Description

technical field [0001] The present invention relates to a coil component and a manufacturing method thereof, and particularly to a coil component having a winding structure in which two wires are wound around a winding core and a manufacturing method thereof. Background technique [0002] Coil components such as transformers, common mode filters, and baluns have a pair of coils that are magnetically coupled to each other. In a wound-type coil component, two wires are wound around a magnetic core to form a pair of coils. [0003] As one of the winding structures in the winding type coil component, a two-layer winding structure is known. In a general two-layer winding structure, after the first wire is wound into the first layer, the wire of the second layer is wound on the winding of the first layer. However, in a general two-layer winding structure, the second layer is wound after the first layer is wound, so the winding operation time (takt time) until all two wires are wo...

Problems solved by technology

[0005] However, in the conventional coil component described in Japanese Patent No. 4148115, since the same turns of the first wire and the second wire are not adjacent to each other and separated by a distance between the wires, the magnetic coupling between the same turns is low. The problem

In addition, since there is a distance between the wires of the same turn, it is difficult to wind the same turn at the same time with high precision, and there are also problems such as winding collapse and winding disorder.
