Abstract

The invention provides a coil device with a high degree of freedom of design. A transformer (10) is provided with: a bobbin (20) around which a first winding wire (37) constituting a first coil part (35) and a second winding wire (38) constituting a second coil part (36) are wound; a first terminal block (81) in which a pair of first lead portions (37a, 37b) of the first winding (37) are led out;and a first insulating plate (91), at least a part of which is located between the first lead parts (37a, 37b) led out to the first terminal block (81) and a case (100) housing the bobbin (20). The first terminal block (81) is formed separately from the frame (20) and is attached to the frame (20). The first insulating plate (91) is formed separately from the first terminal block (81) and is attached to the first terminal block (81).

Description

technical field [0001] The present invention relates to a coil arrangement suitable for use as, for example, a transformer or the like. Background technique [0002] Patent Document 1 discloses a coil device including a terminal block from which a pair of lead wire portions of a wound wire are drawn out. However, in the coil device of Patent Document 1, the terminal block and the bobbin are integrally formed. Therefore, when the specification of the terminal block is changed, the entire bobbin must be replaced from scratch, and the degree of freedom in design is low. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-254890 Contents of the invention [0006] The present invention has been made in view of the current situation, and an object of the present invention is to provide a coil device with a high degree of freedom in design. [0007] In order to achieve the above object, the coil device accordi...
