To provide a flat-conductor connector that implements, with a simple structure, a function of preventing a flat conductor from coming out thereof. A flat-conductor connector includes a housing including a holding portion into which a flat conductor is inserted to be electrically connected. The housing includes a deformation guiding portion that comes into contact with the flat conductor and that causes a side edge portion of the flat conductor to be curved and deformed in a thickness direction and a retaining engagement portion that is located on a far side of the deformation guiding portion in an insertion direction of the flat conductor and that engages an edge of a recess formed in the side edge portion of the flat conductor that has returned from a state of being curved and deformed to its original shape, in a direction in which the flat conductor is to be pulled.

To reduce the displacement load of a spring portion in order to improve the workability of insertion and extraction of a movable connector. A spring portion has an upper piece portion and a lower piece portion having a linear shape, and is formed in such a square wave shape that an outer vertical piece portion having a linear portion extends from a first end of the upper piece portion, a central vertical piece portion having a linear shape and connected to a first end of the lower piece portion extends from a second end of the upper piece portion, and an inner vertical piece portion having a linear shape extends from a second end of the lower piece portion.

Movable connector

A connector includes a housing that has a fitting chamber with an insertion opening for a flat conductor in the upper surface thereof and whose lower side is placed on a circuit board, a locking spring that locks the flat conductor, and an unlocking member. The locking spring is provided with a housing fixing portion, an elastic arm that is rotationally displaced about the housing fixing portion away from the flat conductor, an engaging piece that engages with a locking portion of a through-shape provided in the flat conductor, and a sliding contact portion that comes into oblique sliding contact with the unlocking member displaced by a pressing operation, rotates the elastic arm, and extracts the engaging piece from the locking portion.

Connector

A first space in which terminals are disposed and that is connected to a first connection and a second space in which ground terminals are disposed and that is connected to a second connection are provided in a housing portion of a flat conductor including a plate. Furthermore, in the thickness direction of the flat conductor including a plate, the second space is formed with a size that is equivalent to or greater than the thickness of a ground plate so as to enable the second connection to the housed therein.

A connector includes a lock lever that is fastened to a flat conductor and that maintains electrical connection between a terminal and the flat conductor. The lock lever includes a fastening portion that, in an interior of a fitting chamber, is fastened to the flat conductor that electrically contacts the terminal, and prevents removal of the flat conductor; an elastic portion that displaces the fastening portion in directions towards and away from the flat conductor; and an operation portion that includes a flat plate portion and a connecting portion, the flat plate portion extending along a front wall, the connecting portion extending from the flat plate portion in the direction away from the flat conductor and connected to the elastic portion. The flat plate portion is pushed along an insertion direction of the flat conductor.

A housing of a linear conductor connection terminal is provided with a first contact point portion having a recessed portion composed of a metal plate and opening inwardly of the housing. The recessed portion allows insertion of a linear conductor inserted into the housing from an insertion port. The housing is further provided with a second contact point portion that supports contact between the linear conductor and the first contact point portion. This allows the linear conductor to reliably conductively contact the first contact point portion and the second contact point portion.

Linear conductor connection terminal

A connector includes a terminal, a housing configured to hold the terminal and having an insertion port for a flat conductor and a fitting chamber where the flat conductor and the terminal are in conductive contact, and an engaging projection with which the flat conductor engages in a removing direction inside the fitting chamber. The flat conductor includes an engaging recess provided in a side edge portion along an inserting direction in the fitting chamber and having an engaging edge portion configured to abut on and engage with the engaging projection in the removing direction, and a projecting piece part located between the engaging edge portion and a distal end part of the flat conductor. The fitting chamber has an escape space. When the flat conductor is removed, the projecting piece part abuts on the engaging projection, and is displaced in the inserting direction to enter the escape space.

An electric connector including a housing having an insertion opening for a flat conductor, a connector terminal that is conductively connected to the flat conductor, an actuator having a pressing surface, and a shaft portion. The connector terminal is provided with a terminal portion that comes in contact with the flat conductor and a base end that supports the terminal portion. The terminal portion is provided with a front terminal that includes a front contact portion that is provided on an insertion opening side with respect to the shaft portion so as to face the pressing surface and a rear terminal that includes a rear contact portion that is provided on the rear side of the housing with respect to the pressing surface and at a position that is closer to the pressing surface with respect to the front contact portion.

Electric connector

Provided is a connector in which a decrease in contact pressure due to the shape degradation of the pressing portions does not occur even if the operation of rotating the pressing member is repeated. Since the connector main body has, at the rear end, supporting portions that rotatably support the pressing portion, the pressing portion rotates while butting the rear ends of the movable pieces and the supporting portions so that the rear ends of the movable pieces are pushed up by the pressing portion, the butting of the pressing portion and the supporting portions is contact between synthetic-resin components, this eliminates the pressing portion being cut off due to contact with the supporting portions even if the rotation of the pressing member is repeated, and hence the shape degradation of the pressing portion can be prevented.

A connector which, when two contacts contact a connection object at positions different from each other in the insertion/extraction direction of the connection object, suppresses deflection of the connection object without increasing a pressing member size. The connector configured so, when the pressing member is rotated to a closed position, a pressing plate is brought into surface contact with the other thickness direction surface of a flexible circuit while pressed by a pressing member pressing portion, and a range including the contact positions between the flexible circuit and first and second contacts is pressed from the side of the other thickness direction surface of the flexible circuit via the pressing plate, so one thickness direction surface of the flexible circuit is brought into press-contact with the first and second contacts. Deflection of the flexible circuit is suppressed by the pressing plate, and the pressing member size need not be increased.
