Embodiment Construction

[0057] Below, will be based on Figure 1 to Figure 8 The coil component and the wiring method of the coil component according to the embodiment of the present invention will be described. figure 1 The shown coil component 1 mainly includes an iron core 2 , terminal fittings 5 ​​and winding wires 6 .

[0058] The core 2 is composed of a drum core 3 and an outer peripheral core 4 . Drum core 3 is provided with substantially disk-shaped flanges 3A at both ends, and the flanges 3A at both ends are connected by winding cores (not shown) around which winding wire 6 is wound. The outer peripheral core 4 has an octagonal substantially annular shape, and a hole 4 a into which the drum core 3 can be inserted is formed at the center of the octagon. In addition, a groove-shaped recess 4b is formed on one end surface (upper end surface) of the hole 4a in the penetrating direction of the outer peripheral core 4 , and the recess 4b extends continuously from the inner surface of the hole 4a...

Abstract

PROBLEM TO BE SOLVED: To provide a line connection method of a coil component simplified in structure of line connection portion. ŽSOLUTION: The line connection is performed including: a core preparation process of preparing a core 2; a terminal fitting preparation process of preparing a holding piece for holding on a terminal fitting 5 an end of wiring 6 pulled out from a core 2 and a melted piece protruding from the holding piece in a direction where the winding 6 held on the holding piece is pulled out from the holding piece; an arrangement process of disposing one end part of the winding 6 along the melted piece and protruding the tip of the one end part from the tip end part of the melted piece and disposing the same on the holding piece; an earth process of taking a ground electrode for arc welding on the other end of the winding 6; a discharge process of performing arc discharge from the tip of the one end part of the winding 6; and a welding ball forming process of melting the tip of the one end part therefrom by arc formed in the discharge process and forming a welded ball together with the one end part and the melted piece.

Description

Technical field [0001] The invention involves a wiring method of a coil part, especially a welded wiring method. Background technique [0002] The coil parts have iron hearts, rolls that are wrapped in iron, and the terminal accessories that are assembled in the installation site that are assembled in the iron heart and wiring rolls at the same time. Tin welding is used when the roll line is wiring to the terminal accessories of the roll line.In the tin welding roll line, in order to reliable tin welding through the sewing of the tin welding site in advance, tin welding is reliable, and tin welding and other tin welding are required for treatment. [0003] In order to omit this extra procedure, as shown in Patent Literature 1, the applicant publicized the method of integrating the electrical and mechanical electrical of the roll line and the terminal accessories through welding. [0004] Patent Literature 1: Japan Special Development 2007-258201 Bulletin [0005] In order to use ...
