Abstract

The embodiment of the present application discloses a conductive brush, an antenna assembly, and a mobile terminal. The conductive brush is used to electrically connect the circuit board and the antenna of the mobile terminal. The conductive brush includes one or more conductive plates, and A plurality of elastic conductive fiber threads; the elastic conductive fiber thread includes a fixed end and a free end, the fixed end of the elastic conductive fiber thread is fixed on the conductive plate, and the free end of the elastic conductive fiber thread is used for connecting with The antenna is electrically connected, and the elastic conductive fiber filament produces a first deformation when subjected to a first pressure from the antenna, and the first deformation recovers after the first pressure disappears. Therefore, the elastic conductive fiber has good flexibility, and can be bent after being subjected to external pressure, and the stress after bending is small, so as to avoid damage to the antenna in contact with it due to excessive stress, and the elastic conductive fiber is bent under pressure After that, it can be spread out, which increases the contact area of ​​the contacts and improves the electrical connection performance.

Description

technical field [0001] The embodiments of the present application relate to the field of electronic devices, and in particular, to a conductive brush, an antenna assembly, and a mobile terminal. Background technique [0002] With the explosive growth of information traffic in today's society, people have higher and higher requirements for the communication capabilities of mobile terminals such as mobile phones. Therefore, more new frequency band antennas and MIMO antennas need to be added to mobile terminals to meet this demand. However, the area suitable for placing the antenna on the mobile terminal is limited, and it is also becoming less and less with the trend of ID and the development of display screen technology. Therefore, antenna designers hope that the antenna can be placed on the back cover or the cover above the display screen. [0003] Traditional mobile terminal antennas mostly realize the connection between the circuit board and the antenna through metal shee...
