Connector for a flexible printed circuit

A connector comprising:

• a housing having an insertion portion into which a flexible substrate is inserted;
• and
• a contact having a contacting portion to be in contact with a connection terminal of the flexible printed circuit having been inserted into the insertion portion, wherein
• a lock part for locking an inserted state of the flexible printed circuit having been inserted into the insertion portion is provided in the housing on both sides of the insertion portion in a width direction,
• each of the lock parts has an arm portion and a projected portion which is formed on an inner side portion of the arm portion in the width direction and protruded into the insertion portion, where the arm portion has a cantilever shape with a stationary end and a free end, extends, in a depth direction orthogonal to the width direction, to the free end from an insertion side portion on a side from which the flexible printed circuit is inserted, and can be elastically deflected outward in the width direction,
• the projected portion has a tilted portion toward the free end and a tilted portion toward the insertion side portion, the tilted portions being tilted relative to the depth direction, and is detachably engaged with a notch provided on a side of the flexible printed circuit in the width direction when the flexible printed circuit is an inserted state,
• the arm portion is curved in a U shape at the insertion side portion,
• the arm portion has a turned-back portion at the insertion side portion on the side from which the flexible printed circuit is inserted, the turned-back portion being between the stationary end and the free end and being curved in the U shape;
• and
• the turned-back portion of the arm portion is exposed from the housing at the insertion side portion on the side from which the flexible printed circuit is inserted.
