At the time of this insertion, the protruding portions 88 of the side surface portions 84 of the FPC 82 abut on the lower sides of the respective protruding portions 56 formed on the one side surface 30 side and the other side surface 32 side of the arrangement portion 52 in the housing 12. When the insertion of the FPC 82 is advanced, the protruding portion 88 of the FPC 82 advances through the gap 60 below the protruding portion 56 along the inclined surface 58 of the protruding portion 56, and the entire FPC 82 is located on the bottom surface 26 side of the placement portion 52, that is, It proceeds on the side adjacent to the contact 62.

  When the insertion of the FPC 82 is further advanced, the distal end side of the FPC 82 comes into contact with the inclined portion 72 of the arm portion 70 of the contact 62. In this state, when the insertion is further advanced, the FPC 82 passes below the protrusion 56 so that the entire FPC 82 moves along the contact 62 side. Therefore, the FPC 82 advances while pressing the inclined portion 72 of the contact 62, The entire portion 70 is elastically deformed about the bent portion 64, and the arm portion 70 moves so as to approach the main body portion 66 (see FIGS. 7B and 8B). At this time, the contact portion 74 of the arm portion 70 comes into contact with the conductor portion 90 of the FPC 82.

  Further, when the insertion of the FPC 82 is further advanced and the projecting portion 88 of the FPC 82 passes through the projection 56, the rear side insertion hole 38, the one notch side surface 42, and the other notch side surface 44 of the notch rear surface 36 of the housing 12. The protruding portion 88 protrudes and is exposed from the side-side insertion hole 46 to the notch 34, reaches a predetermined position, and the protruding portion 56 and the recessed portion 86 of the FPC 82 are arranged at corresponding positions. Then, the FPC 82 that has been moved below the placement portion 52 by the protrusion 56 is pressed upward, that is, toward the upper surface 24 of the housing 12 by the elastic force of the arm portion 70 of the elastically deformed contact 62. Then, the protrusion 56 is fitted into the recess 86 (see FIGS. 1B, 7C, and 8C).

  At this time, the FPC 82 is constantly receiving an upward pressing force by the arm portion 70 of the contact 62, so that the FPC 82 does not move downward, and the protruding portion 56 and the recessed portion 86 are kept in a fitted state. Thus, the protrusion 56 and the protrusion 88 can be fixed, and the connection between the connector 10 and the FPC 82 is completed. When the connection of the FPC 82 to the connector 10 is completed, the protrusion 88 of the FPC 82 is exposed from the notch 34 of the housing 12 (see FIG. 1B). Further, when the FPC 82 moves upward, the projecting portion 88 of the FPC 82 moves along the side surface insertion hole 46 of the one notch side surface 42 and the other notch side surface 44.

  Next, a method for releasing the connection between the connector 10 and the FPC 82 will be described mainly with reference to FIG. As a method of releasing the connection between the connector 10 and the FPC 82, first, the fixation of the FPC 82 connected to the connector 10 is released. This fixing is released by pressing the protruding portion 88 of the FPC 82 exposed from the notch portion 34 of the housing 12 downward, that is, toward the contact accommodating portion 50 (see arrow F1 in FIG. 9A). At this time, the whole FPC 82 moves downward together with the protruding portion 88 of the pressed FPC 82. The movement of the entire FPC 82 causes the arm portion 70 to be pressed together with the contact portion 74 of each contact 62, so that the arm portion 70 moves closer to the main body portion 66 around the bent portion 64. At this time, the protruding portion 88 of the FPC 82 moves along the side surface insertion hole 46 of the one notch side surface 42 and the other notch side surface 44.
