The FPC 20 can be guided by the inner wall 1aa up to a position where it is normally connected. Thereby, the connector 10 of this embodiment can make it easy to insert the FPC 20 with the protruding portion 20a protruding in the width direction into the housing 1. That is, as shown in FIG. 2, the connector 10 of the present embodiment includes a virtual center line (see the one-dot chain line in FIG. 2) in the FPC 20 and a virtual center line (see the chain line in FIG. 2) in the housing 1. It is not always necessary to insert them so that they match exactly.

  Further, the inner wall 1aa of the connector 10 of the present embodiment has the inclined surface that does not cause the protruding portion 20a and the inner wall 1aa to interfere until the FPC 20 is drawn into a position where the conductor pattern 21 and the contact portions 3aa, 4aa are in pressure contact with each other. Have. As a result, the connector 10 can more smoothly accommodate the protruding portion 20a of the FPC 20 in the accommodation recess 1a.

  Hereinafter, an operation when the FPC 20 is inserted into and removed from the connector 10 of the present embodiment will be described.

  Before connecting the FPC 20, the connector 10 is disposed at a position where the lever 5 is raised with respect to the housing 1 as shown in FIGS. 1 and 2. Accordingly, the connector 10 is in a position where the lever 5 does not press the FPC 20 (hereinafter also referred to as a non-preventing position).

  The connector 10 can reduce the insertion resistance when the FPC 20 is inserted into the connector 10 in the non-removable position, and the soft FPC 20 can be easily inserted into the connector 10. The connector 10 may be such that the first contact portion 3aa of the first contact 3 and the second contact portion 4aa of the second contact 4 are in contact with the FPC 20 in a state where the lever 5 is in the non-removable position. The connector 10 is electrically connected to the FPC 20 at the same time as the FPC 20 is inserted when the first contact 3 aa of the first contact 3 and the second contact 4 aa of the second contact 4 are in contact with the FPC 20 even when the lever 5 is in the non-removable position. Connection can be established. Note that the connector 10 has a relatively small holding force for the contacts 3 and 4 to hold the FPC 20 as compared with the case where the lever 5 is in a position where the lever 5 presses the FPC 20 (hereinafter also referred to as a retaining position). Therefore, the FPC 20 is in a state that is relatively easily removed.

  When the FPC 20 is inserted into the housing 1 from the opening 1d side with the lever 5 placed in the non-removable position, the connector 10 has the tip of the FPC 20 even when the FPC 20 and the housing 1 are displaced in the width direction. The FPC 20 is guided along the inner wall 1aa. That is, in the connector 10, the FPC 20 is inserted along the inclined surface of the inner wall 1aa constituting the housing recess 1a. The connector 10 can reduce the positional deviation between the conductor pattern 21 of the FPC 20 and the first contact portion 3aa or the second contact portion 4aa as the FPC 20 moves toward the inside of the housing 1.

  The FPC 20 inserted into the connector 10 comes into contact with the positioning surface 1s on which the front end side of the FPC 20 restricts the insertion of the FPC 20 and performs positioning. Accordingly, the connector 10 can position the position of the front end side of the FPC 20 in the insertion / extraction direction of the FPC 20 with respect to the contacts 3 and 4. At the same time, the projecting portion 20a of the FPC 20 is housed in the housing recess 1a.

  In the state where the lever 5 is rotated to the retaining position, the FPC 20 is pressed against the first contact portion 3aa of the contact piece 3b and the second contact portion 4aa of the contact piece 4a. The connector 10 sandwiches the FPC 20 between the first contact portion 3aa of the contact piece 3b and the pressing surface 5c of the lever 5. In addition, the connector 10 sandwiches the FPC 20 between the second contact portion 4aa of the contact piece 4a and the pressing surface 5c of the lever 5. As a result, the connector 10 is in a state where the first contact 3 and the second contact 4 are electrically connected to the conductor pattern 21 of the FPC 20.

  On the other hand, when the lever 10 is rotated from the retaining position to the non-preventing position, the connector 10 weakens the force with which the lever 5 and the first contact 3 and the second contact 4 hold the FPC 20, thereby facilitating pulling out the FPC 20. Is possible.
