Embodiments of the present invention provide a wireless terminal device, including: a subscriber card holder, a mainboard, a secondary board, and a housing, where the mainboard, the secondary board, and the subscriber card holder are located in the housing, the subscriber card holder is disposed on the secondary board, the secondary board is fixed to the housing so that the subscriber card holder is separated from the mainboard spatially, and the secondary board is connected to the mainboard in a low thermal conductivity manner. According to the wireless terminal device disclosed in the embodiments of the present invention, a subscriber card and a subscriber card holder are fixed to a housing, so that the subscriber card and the subscriber card holder are isolated from a mainboard spatially. This effectively prevents heat generated by an exothermic component on the mainboard from being conducted to the subscriber card, thereby preventing deformation of the subscriber card. |
