Pressing Device and Electrical Connection

An electrical connection assembly, comprising:

• a circuit board having a front surface and a back surface opposite in a thickness direction of the circuit board;
• a connector installed on the front surface of the circuit board;
• and
• a pressing device including a bottom plate and a pressing rod member, an elastic buckle is formed on the bottom plate, the pressing rod member is rotatably connected to the bottom plate and is rotatable between a closed position of pressing the connector onto the circuit board and an open position of releasing the connector, the elastic buckle engages with the pressing rod member when the pressing rod member is rotated to the closed position, the elastic buckle engaged with the pressing rod member locks the pressing rod member in the closed position, the bottom plate is fixed to the front surface of the circuit board, the pressing device applies a predetermined pressing force on the connector, such that the connector is pressed against the front surface of the circuit board.
