Abstract

In a coil device for an antenna, a wide surface of a connector connecting section and a mounting surface of a fixing section are substantially vertically arranged. A connecter terminal can take a first arrangement or a second arrangement to a resin member. In the first arrangement the connector terminal can take, the connector connecting section is positioned on one end side in the width direction of the resin member, and in the second arrangement, the connector connecting section is positioned on the other end side in the width direction of the resin member by turning the connector connecting section in the first arrangement 180 degrees.

Claims

1. A coil device for antenna comprising:

a winding coil;

a bar-like magnetic core inserted into the winding coil;

a connector terminal provided with a connector connecting section and a first engaging portion for engaging one end of the winding coil thereto;

a mounting terminal provided with a fixing section having a mounting surface, and a second engaging portion for engaging the other end of the winding coil thereto; and

a resin member to which the mounting terminal and the connector terminal are attached and on which the winding coil is mounted,

wherein a wide surface of the connector connecting section is perpendicular to the mounting surface of the fixing section, and

wherein the connector terminal can take a first arrangement or a second arrangement to the resin member, where in the first arrangement, the connector connecting section is positioned on one end side in the width direction of the resin member, and in the second arrangement, the connector connecting section is positioned on the other end side in the width direction of the resin member by turning the connector connecting section in the first arrangement 180 degrees.

2. The coil device for antenna according to claim 1, wherein a line connecting a winding start point of the one end of the winding coil and a center point of a winding axis of the winding coil and a line connecting a winding end point of the other end of the winding coil and the center point of the winding axis of the winding coil are both substantially in parallel with the mounting surface and the fixing section.

3. A antenna system for rear window of vehicle comprising a coil device for antenna according to claim 1 or 2.
