Card edge connector with terminal fitting configured to pivot in a housing in response to differential thermal expansion for avoiding abrasion of contact portion of terminal fitting

A card edge connector, comprising:

• terminal fittings each including a body and a resilient tongue continuously formed in the body, the resilient tongue having a contact portion, the contact portion being resiliently deflectable while projecting outward from the body;
• a harness-side connector including a harness-side housing, the terminal fittings being accommodated in a plurality of cavities formed side by side in the harness-side housing;
• and
• a board-side connector including a board-side housing, a circuit board being mounted in the board-side housing;
• the contact portion resiliently contacting the circuit board when the harness-side housing is connected to the board-side housing, whereby a part of the body on an opposite side in a deflection direction of the resilient tongue serves as an abutting part to be pressed into contact with an inner wall of the cavity,
• wherein one of the body and the inner wall of the cavity is formed with an escaping portion with respect to the inner wall of the cavity formed laterally to the abutting part in an arrangement direction of the cavities such that the terminal fitting pivots with the resiliently deflectable contact portion and the circuit board serving as a supporting point when there is a thermal expansion difference in the arrangement direction of the cavities between the circuit board and the harness-side housing.
