It is arranged and attached to the housing 60 by screwing a screw 63 into the attachment hole 54 and the attachment wall 61. The mobile terminal antenna 10 is inserted into the cylindrical portion 51 of the holder 50 so as to be extendable and retractable, and can be pulled out from the housing 60 and accommodated in the housing 60. When the mobile terminal antenna 10 is pulled out, the contact portion 331 of the contact conducting portion 33 slides on the elastic contact piece 52, and the stopper portion 332 of the contact conducting portion 33 comes into contact with the proximal end surface of the cylindrical portion 51, thereby contacting the contact conducting portion. The elastic contact piece 52 contacts the contact portion 331 so as to urge the contact portion 331 of 33. The holder 50 is supplied with power from a power supply unit (not shown), and the contact between the elastic contact piece 52 and the contact unit 331 supplies power to the contact conduction unit 33 and the second antenna element 31, and further from the second antenna element 31. Power is supplied to the first antenna element 21 via the first connector 41, the second connector 42, and the contact conducting tube 24.

上記アンテナ構造は、ホルダー５０の略対向位置に配置されている弾性接触片５２が接触導通部３３の接触部３３１を略対応して付勢するので、アンテナ１０をバランス良く保持することができると共に、接触導通部３３の接触部３３１と弾性接触片５２との接触性、導通性を確実にし、安定化することができる。また、筒部５１や弾性接触片５２を有するホルダー５０をプレス加工で製造することができるので、低コスト化を実現できる。また、ホルダー５０に別部材のバネ材を設ける必要がないことから、部品点数を減らしてアンテナ構造を低コスト化することができると共に、ホルダー内にバネ材を収容する作業を無くし、労力低減を図ることができる。   In the antenna structure described above, the elastic contact piece 52 disposed substantially at the position facing the holder 50 biases the contact portion 331 of the contact conducting portion 33 in a substantially corresponding manner, so that the antenna 10 can be held in a well-balanced manner. The contact property and conductivity between the contact portion 331 of the contact conduction portion 33 and the elastic contact piece 52 can be ensured and stabilized. Moreover, since the holder 50 having the cylindrical portion 51 and the elastic contact piece 52 can be manufactured by press working, cost reduction can be realized. In addition, since it is not necessary to provide a separate spring material for the holder 50, the number of parts can be reduced to reduce the cost of the antenna structure, and the work for housing the spring material in the holder can be eliminated, reducing labor. Can be planned.

本発明は、例えば携帯電話等の携帯端末のアンテナ構造として利用することができる。   The present invention can be used as an antenna structure of a mobile terminal such as a mobile phone.
