Mobile terminal

Abstract

The invention provides a mobile terminal and relates to the technical field of communication. The mobile terminal comprises a shell and a card tray. An insertion slot for egress and ingress of the card tray is set on the shell. The mobile terminal also comprises a blocking door, a sliding block, a compression spring and a spring stopping block. The blocking door is mounted at the inner side of theshell in an egress and ingress direction of the card tray. The spring stopping block is fixed on the shell and is located at the end of a sliding direction of the sliding block away from a blocking slot. The compression spring is mounted between the sliding block and the spring stopping block. When the card tray is inserted into the insertion slot, the card tray pushes the sliding block to move to a first position away from the insertion slot. When the blocking door withdraws from the blocking slot, the blocking door is opened. When the card tray withdraws from the insertion slot, the compression spring pushes the sliding block to move to a second position close to the insertion slot. When the blocking slot blocks the blocking door, the blocking door is closed. According to the mobile terminal, the blocking door is blocked by the blocking slot on the sliding block and the blocking door is prevented from being opened, so a foreign matter is prevented from entering the terminal, the risk of damaging the terminal is reduced, and the disassemble maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a mobile terminal. Background technique [0002] With the continuous development of mobile terminals (such as mobile phones), they have gradually become indispensable and practical tools in people's daily life, and their application scenarios are becoming more and more complex. It is a common design for mobile terminals to provide a slot on the housing of the mobile terminal to accommodate the card tray. figure 1 It is a schematic structural diagram of a common mobile terminal housing, and the card tray 10 is inserted or removed through the slot 111 on the housing body 11 . [0003] However, when the above housing structure is applied, when the card tray 10 is taken out from the slot 111 on the housing body 11, the slot 111 on the housing body 2 will appear as an open hole, which will directly move The internal space of the terminal is connected with the exte...
