9. A method of mounting a circuit board assembly for a communication device according to any one of claims 1 to 8, wherein: the installation steps are as follows:
A. the protective cover (3) is placed in the inner cavity of the positioning ring groove (20), and the fixing plates (4) on the two sides of the protective cover (3) can drive the fixing rods (5) to extend to the inner cavity of the fastening box body (7) through the limiting holes (6);
B. the reset elasticity of the reset spring (10) can drive the pulling plate (9) and the fixed pin rod (8) to reset, the fixed pin rod (8) can be inserted into the surface of the fixed rod (5), and therefore the fixed pin rod (8) is used for fixing the fixed rod (5) to fix the protective cover (3);
C. after the protective cover (3) is fixed, the brush plate (16) is respectively fixed with the first linkage rod (15) and the second linkage rod (19) in a threaded manner through bolts;
D. an output shaft of the servo motor (11) can drive a threaded rod (12) to rotate, the threaded rod (12) drives a threaded sleeve (13) and a first linkage rod (15) to move, and the first linkage rod (15) slides in an inner cavity of a limiting sliding hole (14), so that a brush plate (16) is driven to move at the top of the protective cover (3), and dust is removed from the top of the protective cover (3);
E. when the protective cover (3) is detached, the brush plate (16) is detached firstly, then the pulling plate (9) is pulled, the pulling plate (9) drives the fixing pin rod (8) to be separated from the fixing rod (5) for insertion, and the protective cover (3) is directly lifted upwards.
