The cover plate 310 is overlapped on the frame 110, the cover plate 310 and the housing 100 form a containing cavity 400, and the indicator lamp 200 is installed in the containing cavity 400. The indicator lamp 200 is generally fixed within the receiving cavity 400 by a fixing base, thereby achieving the installation thereof. The fixed base may be a circuit board 600 described later. The cover plate 310 is overlapped on the frame 110, and may be fixedly connected to the frame 110 through other intermediate members, which may be transparent adhesive 500 described later, of course, the intermediate members are not limited to the transparent adhesive 500, as long as the installation manner meets the assembly requirement of the mobile terminal.

In the embodiment of the present invention, the frame 110 includes the light guide portion 111 disposed opposite to the indicator lamp 200, the cover plate 310 is overlapped on the light guide portion 111, and the light guide portion 111 can transmit light of the indicator lamp 200. The cover plate 310 is used for transmitting the light of the indicator lamp 200 guided out by the light guide portion 111, thereby achieving the light of the indicator lamp 200. The arrangement of the light guide 111 and the indicator lamp 200 relative to each other means that the arrangement position of the light guide 111 can be irradiated with the indicator lamp 200 so that the light guide 111 guides the light of the indicator lamp 200. Specifically, the light guide portion 111 may be disposed opposite to the indicator lamp 200, or may be disposed at an angle offset from the indicator lamp 200.

In the operation process of the mobile terminal, the light emitted by the indicator lamp 200 enters the light guide portion 111, and then is emitted from the light guide portion 111 through the cover plate 310, and finally the indicating function is realized by the emitted light.
