摘要:
A mobile terminal includes a terminal main body, a circuit board, an antenna device and a connecting portion. The terminal main body has a plurality of members. The circuit board and an antenna device are built in the terminal main body so as to be spaced apart from each other. The connecting portion electrically connects the circuit board and the antenna device to each other. In the mobile terminal, the connecting portion is a conductive pattern formed on one surface of at least one of the members defining an internal space of the terminal main body.

A mobile terminal including a main body having an accommodating chamber; a circuit board mounted at the main body; and connecting terminals disposed on the circuit board to be electrically connected to a battery having terminals. Further, when the battery is mounted in the accommodation chamber, the connecting terminals are pressed by the battery terminals to be elastically deformed. In addition, each of the connecting terminals includes a base portion electrically connected to the circuit board; an elastic portion having a first section extending from the base portion and a second section curved from the first section to have an inclination; and first and second contact portions extending from the second section to be contactable with the battery terminals.
