Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 and figure 2 As shown, the antenna structure of the mobile terminal of the present invention includes a metal rear shell 1 with an antenna 2, and a metal stud 3 for connecting a PCB board 4 is provided at the antenna 2 in the metal rear shell 1, and the metal stud 3 3 is connected to the antenna 2, and the PCB board 4 is provided with a screw hole 5 corresponding to the position of the metal stud 3, and the area around the screw hole 5 is an exposed copper area 10, which is connected to the antenna 2 as an antenna feed point, Space is saved. A metal shrapnel 6 is provided between the PCB board 4 and the metal stud 3. The metal shrapnel 6 is ring-shaped, preferably circular, and the locking screw 7 passes through the screw hole 5 and the inside of the metal shrapnel 6. The hole is screwed to the metal stud 3, so that ...

The present invention provides a mobile terminal antenna structure. The antenna structure comprises a metal rear housing with an antenna, a metal double-screw bolt configured to connect a PCB is arranged at the antenna in the metal rear housing, the metal double-screw bolt is connected with the antenna, a screw hole is arranged at the position corresponding to the position of the metal double-screw bolt on the PCB, an exposed copper area is arranged at the peripheral region of the screw hole, the PCB is threadedly connected with the metal double-screw bolt through a locking screw to allow the exposed copper area of the screw hole to connect with the metal double-screw bolt, a metal shrapnel is arranged between the PCB and the metal double-screw bolt, the metal shrapnel is connected and conducted with the exposed copper area and the metal double-screw bolt, the metal shrapnel is annular, and the locking screw passes through the metal shrapnel to connect with the metal double-screw bolt. The present invention further provides a mobile terminal and a mobile phone. Compared to the prior art, a metal shrapnel is arranged between the PCB and the metal double-screw bolt to allow the PCB to conduct with the metal double-screw bolt through the metal shrapnel and form elastic connection between the PCB and the metal double-screw bolt so as to improve the connection reliability and avoid generation of the problem bad contact.
Description
technical field [0001] The invention relates to a mobile terminal, in particular to an antenna connection structure of a mobile terminal, a mobile terminal and a mobile phone. Background technique [0002] At present, mobile terminals using metal back shells generally use the frame of the metal back shell as the mobile phone antenna, which can save costs. However, with this structure, it is necessary to connect the metal back shell to the PCB board. In order to save space, screws are usually used to connect the The PCB board is locked to the metal part (metal stud) as the antenna, and the area around the screw hole of the PCB board is set as an exposed copper area, and the PCB board is connected to the metal stud by locking screws. This way the lock The position of the screw and the position of the antenna feed point are combined into one, so a space is saved. However, the disadvantage of this connection method is that the PCB board and the metal stud are locked by the locki...
