Abstract: A connector includes a contact, a housing, and an actuator. The housing holds and fixes the contact. The actuator presses an FPC, an object to be connected, and thereby connects the FPC and the contact. The connector further includes a first member that is fixed to the housing. The housing includes an insertion slot therein the FPC is inserted and thereto an open portion is formed. The first member includes a projection segment that projects toward the open portion of the insertion slot. The projection segment is provided with a chamfered portion on a side facing the open portion of the insertion slot.

Abstract: For connecting an object having protruding portions protruding reverse to each other in a first direction, a connector includes a housing for guiding the object to an inserted position in a second direction perpendicular to the first direction, a contact held by the housing, and an actuator movable in a predetermined direction with respect to the housing so as to bring the object into press contact with the contact. The housing has receiving portions for receiving the protruding portions, respectively. The actuator has cover portions to face the receiving portions and to cover the protruding portions, respectively, when the object is brought into press contact with the contact. The cover portions respectively having slant surfaces to be engaged with the protruding portions of the object, when the object is located at a position deviated from the inserted position, to force the object towards the inserted position following the movement of the actuator to bring the object into press contact with the contact.
