Abstract

The invention provides an antenna coil device (100) including: a connector unit (10) mounted with a connector of an external circuit detachably by being plugged-in; and a base unit (30) provided with an antenna body (40) including a coil (42), in which the connector unit (10) and the base unit (30) are constituted by separate members and are used by being combined integrally each other, wherein for the connector unit (10) and the base unit (30), there are formed a connector fitting portion (12) and a base fitting portion (32) which are formed with a concave and a convex in a direction intersecting with respect to the plug-in direction of the connector unit (10), and by fitting the connector fitting portion (12) and the base fitting portion (32), the connector unit (10) and the base unit (30) are combined in a state in which the antenna body is positioned with respect to the connector unit (10).

Description

technical field [0001] The present invention relates to a coil device for an antenna. Background technique [0002] In recent years, a smart electronic key system installed in a vehicle and using a coil device for an antenna has been put into practical use. In the smart electronic key system, when the driver holding the electronic key approaches the vehicle and enters the communication range of the system, the antenna coil device communicates with the electronic key, and the control circuit on the vehicle side connected to the antenna coil device is Will allow the driver to unlock the doors and start the engine. In addition, when the driver holding the electronic key is away from the vehicle and comes out of the communication range of the system, the control circuit on the vehicle side will drive the door to lock again. [0003] Japanese Patent Document 1 and Patent Document 2 clearly describe such an antenna coil device. In the antenna coil device of Japanese Patent Docu...
