Card edge connector with a connection terminal including a resilient contact piece

A card edge connector, comprising:

• a housing;
• a receptacle to be mounted on an end part of a circuit board, the receptacle being fit to the housing;
• a connection terminal including a resilient contact piece to be brought into contact with a surface of the circuit board and a pressure receiving portion for displacing the resilient contact piece in a direction toward the surface of the circuit board by being pressed, the connection terminal being mounted in the housing;
• and
• a pressure holding member to be mounted into the housing, the pressure holding member including a pressing portion for pressing the pressure receiving portion,
• the receptacle including a slope, the pressure holding member being displaced along the slope to increase a pressing stroke of the pressing portion for the pressure receiving portion as the housing is further fit into the receptacle, and
• the resilient contact piece being displaced toward a board accommodating portion for accommodating the circuit board and contacting the surface of the circuit board accommodated in the board accommodating portion while pressing the surface of the circuit board as the pressing stroke increases,
• wherein the connection terminal is formed with a recess, the pressing portion being insertable into the recess in a state where mounting of the connection terminal into the housing is completed.
