1. A circuit board assembly, comprising:
a bracket; and
a circuit board, wherein the circuit board is formed with a fastened part and a free part, the fastened part is connected to the bracket, the free part is suspended, a surface on which the free part and the fastened part are co-located is a first plane, the free part has an amplitude of swing in a first direction, the first direction is perpendicular to the first plane, the circuit board is configured to plug-connect to a front sub-circuit board, a first connector is plug-connected to a first plug-connection end on the front sub-circuit board and is disposed on the free part, and the amplitude of swing of the free part is capable of enabling the first connector to plug-connect to the first plug-connection end,
wherein the circuit board is connected to the bracket by using a fastener, a first positioning structure is disposed at a location at which the fastener cooperates with the bracket, and/or a second positioning structure is disposed at a location at which the fastener cooperates with the circuit board, the first positioning structure is configured to prevent the circuit board and the fastener from moving relative to the bracket in a direction perpendicular to the circuit board, and the second positioning structure is configured to prevent the circuit board from moving relative to the fastener in a direction parallel to the circuit board,
wherein the first positioning structure comprises a first positioning column disposed on the fastener and a first positioning hole provided on the bracket, an axial direction of the first positioning column is parallel to the circuit board, the second positioning structure comprises a second positioning column disposed on the fastener and a second positioning hole provided on the circuit board, and an axial direction of the second positioning column is perpendicular to the circuit board.
