1. A card edge connector, comprising:
a housing including a board accommodation space, a circuit board being inserted into the board accommodation space; and
a connection terminal including a resilient contact piece configured to contact the circuit board inserted into the board accommodation space, the connection terminal being mounted into the housing,
wherein:
the connection terminal mounted in the housing is movable between a connection position where the resilient contact piece is in contact with a surface of the circuit board inserted into the board accommodation space and a retraction position where the resilient contact piece is separated from the circuit board,
the resilient contact piece includes a contact portion configured to contact the circuit board,
an interference preventing portion to be contacted by the contact portion is interposed between an entire region of a moving path of the resilient contact piece and an inserting end part of the circuit board inserted in the board accommodation space,
the interference preventing portion restricts the interference of the resilient contact piece and the inserting end part of the circuit board inserted into the board accommodation space in a moving process of the connection terminal, and
a contact point portion in contact with the circuit board, out of the contact portion, is located within a thickness range of the circuit board in a plate thickness direction of the circuit board with the connection terminal located at the retraction position and the inserting end part of the circuit board inserted in the board accommodation space.
