However, as shown in FIG. 4, the connector 10 of the present embodiment is an imaginary center line L1 (see the one-dot chain line in FIG. 4) in the FPC 20 in the imaginary center line L2 with the outer casing 1 (refer to the dotted line in FIG. 4). Before the normal connection position, the FPC 20 can be guided by the inner side wall 1aa. Thereby, the connector 10 of the present embodiment can easily insert the FPC 20 in which the protruding portion 20a is protruded in the width direction into the casing 1. That is, as shown in FIG. 2, the connector 10 of the present embodiment does not necessarily have to have the imaginary center line L1 (see the one-dot chain line in FIG. 2) in the FPC 20 and the imaginary center line L2 in the outer casing 1 (refer to FIG. 2 Dotted line) Insert correctly and consistently.

Further, the inner side wall 1aa of the connector 10 of the present embodiment has the inclined surface which is formed before the FPC 20 is induced to the position where the conductor pattern 21 and the contact portions 3aa and 4aa are pressed, so that the protruding portion 20a and the inner portion are provided. The side walls 1aa do not interfere with each other. Further, as shown in Fig. 4, in the present embodiment, the inner side wall 1aa is formed in a positional relationship in which the protruding portion 20a is not stuck before the FPC 20 is induced to the position where the conductor pattern 21 and the contact portions 3aa and 4aa are pressed. The locking portion 1f is stopped. Thereby, the connector 10 can more easily accommodate the protruding portion 20a of the FPC 20 in the housing recess 1a. Further, in addition to the above, for example, the inner side wall 1aa may be formed as follows. Positional relationship: The protruding portion 20a is not in contact with the outer casing 1 until the FPC 20 is induced to a position where the conductor pattern 21 and the contact portions 3aa and 4aa are crimped.

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

Before the connector 10 is connected to the FPC 20, the rod 5 is placed in the upright position relative to the outer casing 1 as shown in Figs. Thereby, the connector 10 tie rod 5 is located at a position where the FPC 20 is not pushed (hereinafter, also referred to as a non-stop position).

In the non-stopping position, the connector 10 can make the insertion resistance of the FPC 20 inserted into the connector 10 small, and the flexible FPC 20 can be easily inserted into the connector 10. The connector 10 can also bring the first contact portion 3aa of the first joint 3 or the second contact portion 4aa of the second joint 4 into contact with the FPC 20 while the lever 5 is in the non-stop position. The connector 10 can contact the first contact portion 3aa of the first joint 3 or the second contact portion 4aa of the second joint 4 with the FPC 20 even when the lever 5 is in the non-stop position. The FPC 20 is inserted and an electrical connection is established at the same time. Further, in the case where the connector 10 is located at a position where the lever 5 is pressed to push the FPC 20 (hereinafter, also referred to as a stop-off position), the joints 3, 4 maintain the holding force of the FPC 20 in a relatively small state, and thus the FPC 20 is formed in a relative state. The ground is easy to fall off.

When the connector 10 is placed in the non-stop position and the FPC 20 is inserted into the inside of the casing 1 from the side of the opening 1d, the front end of the FPC 20 is still in a state where the FPC 20 and the casing 1 are displaced in the width direction. The inner side wall 1aa guides the FPC 20. That is, the connector 10 is inserted into the FPC 20 along the inclined surface of the inner side wall 1aa constituting the housing recess 1a. In the connector 10, the position of the conductor pattern 21 of the FPC 20 and the first contact portion 3aa or the second contact portion 4aa can be made smaller as the FPC 20 faces the inside of the casing 1.

The FPC 20 inserted into the inside of the connector 10 abuts on the front end side of the FPC 20 to a position determining surface 1s that restricts the insertion of the FPC 20 and performs positioning. With this, The connector 10 can position the front end side of the FPC 20 in the insertion/removal direction of the FPC 20 with respect to the joints 3 and 4. At the same time, the protruding portion 20a of the FPC 20 is housed in the housing recess 1a.

The connector 10 presses the FPC 20 against the first contact portion 3aa of the tab 3b and the second contact portion 4aa of the tab 4a in a state where the lever 5 is rotated to the stop position. The connector 10 holds the FPC 20 between the first contact portion 3aa of the tab 3b and the pressing surface 5c of the lever 5. Further, the connector 10 holds the FPC 20 between the second contact portion 4aa of the tab 4a and the pressing surface 5c of the lever 5. Thereby, the connector 10 is formed in a state in which the first joint 3 and the second joint 4 are electrically connected to the conductor pattern 21 of the FPC 20.

On the other hand, when the connector 10 is rotated from the stop position to the non-stop position, the force of the lever 5 and the first joint 3 and the second joint 4 to hold the FPC 20 is weakened, and the FPC 20 can be easily taken out.

The preferred embodiments of the present invention are described above, but without departing from the spirit and scope of the present invention, that is, without departing from the scope of the patent application, various modifications and variations can be made by those skilled in the art. It goes without saying.
