Further, the movable lid 30 is provided with a one-side guide plate 31 which is provided in a space between the wings 32, and the movable lid 30 is pulled to be separated from the insulating body 20. When the inclination angle is obtained through the rotation, the guide plate 31 is separated from the inside of the fitting groove 21 of the insulating body 20, and the opening of the fitting groove 21 is completely exposed, so that the wiring fitting work is performed. Becomes easier. When the wiring is fitted into the fitting groove 21 of the insulating main body 20, that is, the work of electrically connecting is completed, and then the movable lid 30 and the insulating main body 20 are aligned and positioned. 31 is used to enter the inside of the fitting groove 21 of the insulating body 20, and the wiring is fixed in the fitting groove 21 of the insulating body 20.
However, in the connector of the flexible circuit board having the known structure as described above, the pivot structure between the insulating body and the movable lid is formed by sliding grooves formed on both sides of the insulating body and shafts and projections formed by the wing plate. The movable lid, which has a zigzag shape, has long left and right wing plates in a long plate shape, and a protruding structure such as the shaft forms a pivotal relationship with the insulating body. Therefore, the left and right sides of the movable lid should not be too thick, but this would result in insufficient strength to resist deformation and bending, and as a result, there would be no There is a problem that the wiring is not fixed stably and a contact failure is likely to occur.
