Embodiment Construction

[0038] main reference figure 1 and figure 2 The structure of the coil component 20 manufactured by the manufacturing method of this invention is demonstrated. More specifically, the illustrated coil component 20 constitutes a common mode choke coil as an example of a coil component.

[0039] The coil component 20 includes a core 22 having a winding core portion 21 . The core 22 has a drum shape, and includes a first flange portion 23 and a second flange portion 24 provided at respective ends of the winding core portion 21 . The core 22 is made of, for example, a magnetic material such as ferrite.

[0040] The flange portions 23, 24 respectively have inner end surfaces 25, 26 facing the winding core portion 21 side and positioning the respective ends of the winding core portion 21, and outer end surfaces 27, 28 facing outside on the opposite side of the inner end surfaces 25, 26, It also has bottom surfaces 29 and 30 facing the mounting substrate (not shown) side during m...

Abstract

The invention provides a method of manufacturing a coil component which can reduce the complexity of the shape of metal terminals, the complexity of machining for obtaining metal terminals and the complexity of apparatuses for connecting wires and metal terminals. A metal terminal where a connecting portion (49) has a receiving portion (50) which receives a wire (35) and a contact segment (51) which extends from the receiving portion by way of a bending scheduled portion (55) is prepared. By applying heat and pressure in a state where the wire is placed on the receiving portion for temporarilyfixing the wire, the wire is adhered to the receiving portion using a molten or softened insulating resin coating (39) as an adhesive agent. Next, the connecting portion is bent by way of the bendingscheduled portion such that the contact segment faces the receiving portion by way of the wire and the contact segment is brought into contact with the wire. Next, by irradiating a laser beam to a portion of the metal terminal, the wire and the metal terminal are welded to each other.

Description

technical field [0001] The invention relates to a method for manufacturing a coil component, in particular to a method for connecting wires and metal terminals. Background technique [0002] As a technique of interest in the present invention, there is, for example, the technique described in Japanese Patent No. 4184394 (Patent Document 1). Figure 9 and Figure 10 are drawings cited from Patent Document 1, and correspond to the drawings in Patent Document 1, respectively. figure 2 and Figure 4 . exist Figure 9 and Figure 10 In the drawing, one flange portion 1 which is a part of the core included in the coil component, a metal terminal 2 arranged on the flange portion 1 , and an end portion of a wire 3 connected to the metal terminal 2 are shown. [0003] Such as Figure 9 and Figure 10 As shown, the wire 3 includes a core wire 4 made of a conductor and an insulating resin cover 5 covering the peripheral surface of the core wire 4 . The metal terminal 2 includes ...
