Connectors are delivered with a lock lever opened. You do not have to operate the lock lever before inserting FPC. (picture ① ) Please do not re-flow with the lock lever closed condtion. Please close the lock-lever with inserting FPC, otherwise the contact gap become narrower and FPC insertion force will rise. (picture ② ) picture ① Please do not load (0.3N×pin Min.) from the top of the lock lever. (figure ① ) And please do not load (0.3N×pin Min) toward the opposite direction of the lock lever, (figure ② ) otherwise the lock lever may be broken or contacts may be deformed. 0.3N×pin Min. 0.3N×pin Min. figure ② figure ① 2．FPC Insertion Please insert FPC to the pattern side up.(picture ③④ ) Please insert FPC straight to the connector. Due to the semi-reteining mechanism, some insertion force is necessary when inserting FPC. Please make sure whether FPC is inserted fully.
