Fig. 7 is a plan view showing a state in which the end portion 8a of the flat cable 8 is inserted into the connector 2 of the embodiment. When the end portion 8a of the flat cable 8 is inserted into the contact arranging portion 10, the protruding portion 8b is engaged with the locking member 16, thereby preventing the flat cable 8 from being opened to the open portion when the actuator 6 is in the closed state. 9 sides are prolapsed.

8 is a perspective view showing a state in which the actuator 6 is placed in a closed state and a flat cable is fitted, and FIG. 9 is a cross-sectional view thereof. As shown in FIGS. 8 and 9, the actuator 6 rotates around the rotation shaft 6a in a direction in which it is in a closed state, and when the other end portion 6y of the actuator 6 is pushed downward downward, first, actuation is performed. The lower surface 6β of the device 6 is in contact with the curved portion 16c of the locking member 16. When the other end of the actuator 6 is further When the portion 6y is pushed down, the curved portion 16c is opened toward the outside of the contact arranging portion 10, and the upper surface 6α of the actuator 6 is moved to the lower side of the distal end portion 16d (see Fig. 3) of the curved portion 16c. In this case, the distal end portion 16d is returned to the inner side of the contact arranging portion 10 by the elastic force of the coupling portion 16b, and the distal end portion 16d is placed on the upper side of the actuator 6. Thereby, the actuator 6 is locked by the locking member 16 to prevent returning to the open state, and the actuator 6 is locked to the connector 2.

When the actuator 6 is locked to the connector 2, the flat cable 8 is pushed up by the elasticity of the contact member 12, the lower surface 6β of the actuator 6 and the upper surface of the end portion 8a of the flat cable 8 8α (surface opposite to the circuit board) is in contact. Moreover, the lower surface 8β (surface on the circuit board side) of the flat cable 8 is in contact with the contact portion 12b of the contact 12 . Further, the contact portion 12b of the contact 12 is pressed against the lower surface 8β (surface on the circuit board side) of the flat cable 8 by the elastic force of the contact 12 .

That is, as shown in FIG. 10, it is connected to the circuit board via the rotating shaft 6a, the support portion 14, the side wall portion 11a, the wall portion 11b, and the connecting portion 24. On the other hand, the lower surface 8β (surface on the circuit board side) of the flat cable 8 is connected to the circuit board via the board fixing portion 12a of the contact 12 .

Further, when the actuator 6 is locked to the connector 2, the upper surface 6α of the one end portion 6x of the actuator 6 comes into contact with the front end portion 18a of the pressure receiving portion 18, thereby The pressing portion 18 receives the pressing force from the upper direction of the actuator 6. Thereby, it is possible to prevent the one end portion 6x of the actuator 6 from being subjected to the reaction force from the contact member 12 to cause warping deformation.

Further, when the actuator 6 is locked to the connector 2, the contact portion 12b of the contact 12 is pushed downward by the pressing force of the actuator 6 via the flat cable 8. At this time, the contact portion 12b is deflected downward, and the force to be twisted is applied to the holding portion 20 via the substrate fixing portion 12a.

Here, the fixing portion 22 is provided inside the holding portion 20, and the fixing portion 22 is fixed to the circuit board by the connecting portion 22a (see FIG. 9), so that the holding portion 20 can be prevented from being applied by the substrate fixing portion 12a. The force is reversed.

According to the connector 2 of the above-described embodiment, the contact arrangement portion 10 can be viewed while the actuator 6 is in an open state, and the flat cable 8 can be inserted while the actuator 6 is set to the closed state. The elasticity of the locking member 16 is sensed to confirm that the actuator 6 has been locked, so that the flat cable 8 can be electrically connected to the contact member 12 with an easy operation.

Further, since the upper surface 8α (surface opposite to the circuit board) and the lower surface 8β (surface on the circuit board side) of the flat cable 8 can be respectively transferred to the circuit board, even if the flat cable has a double-layer structure It can also be electrically connected.

Further, when the actuator 6 is in the closed state and the contact portion 12b of the contact 12 is pressed by the actuator 6, the substrate fixing portion 12a of the contact member 12 can be made by the fixing portion 22. Fixed so that the holding portion 20 can be prevented from being twisted This in turn causes damage to the insulator 4. Further, by providing the fixing portion 22 inside the holding portion 20, the substrate fixing portion 12a can be fixed without raising the height of the holding portion 20, so that the connector 2 which is thin and difficult to break can be provided.

Further, in each of the above embodiments, a flexible printed circuit (FPC) or a flexible flat cable (FFC) is used as the flat cable 8.

Further, in each of the above embodiments, the casing 11 does not necessarily need to be insert-molded on the insulator 4, and the casing 11 may be assembled to the insulator 4.
