[0026]
Here, since the upper jaw 71 is in contact with the lower surface of the upper plate 53 and the bending in the Z1 direction is limited, the lower contact arm 72 is reliably bent, and the contact pressure is reliably obtained. .
[0027]
Further, as shown in FIG. 4 (D), the operation unit 82 fits into the concave portion 60a by clicking and fits in the housing portion 60. This prevents an accident that the actuator 80 is inadvertently rotated in the CC direction, and the height of the connector device 50 is the same as the height of the housing 51, so that the connector device 50 has a low profile.
[0028]
The connection of the flexible printed circuit board 40 is released by removing the operation unit 82 from the housing unit 60 and turning the actuator 80 in the CC direction to be inclined, releasing the pinch, and pulling the flexible printed circuit board 40. You.

[0034]
The actuator 90 has a substantially L-shape as shown in FIG. 6, and has a cam portion 91 and an operation portion 92 on the Y2 direction side. The cam portion 91 has a configuration in which the upper surface is a cam surface 93 that is inclined so that the Y2 direction side is higher, and the lower surface is a jagged surface 93 that is obliquely pointed in the Y2 direction. That is, the cam portion 91 has a tapered shape that is narrow on the Y2 side and wide on the Y1 side. The inclined cam surface 93 comes into contact with the upper jaw 71 side. The lower side of the operation unit 92 is an inclined surface 94.
[0035]
As shown in FIG. 6, the actuator 90 fits lateral pins 95, 96 into the grooves 100, 101 on the inner side surfaces of the side plates 54, 55 of the housing 51A from the Y2 side, and the grooves from the Z2 side. The fitting is restricted by the metal fitting 110 for reinforcing the mounting of the connector device 50A inserted and fixed in the insides 103 and 104, and Y1-Y2 is limited to the insertion opening 56 side of the inside of the housing 51A in a limited narrow range. It is movably supported in the direction. The actuator 90 has a degree of freedom in the Z1-Z2 direction within a limited narrow range.
[0036]

The distance a1 between the surface 93 and the contact portion 72a is slightly larger than the thickness t10 of the end of the flexible printed wiring board 40. As shown in FIG. 7B, in a state where the actuator 90 is moved in the Y2 direction and a high portion of the cam surface 93 hits the upper jaw 71, the above-described interval dimension b1 is smaller than that of the flexible printed wiring board 40. It becomes smaller than the thickness t10 of the end.
[0037]
The operation of connecting the flexible printed wiring board 40 is performed as follows. In a state where the actuator 90 is moved to the position where the operating portion 92 hits the housing 51A in the Y1 direction as shown in FIG. 8A, the flexible printed wiring board 40 is moved by the inclined surface 94 as shown in FIG. 8B. The flexible printed circuit board 40 is guided and inserted into the connector device 50A up to the position where it hits the stopper 59, and then the flexible printed wiring board 40 is slightly pulled in the Y2 direction. That is, the operation is a one-action operation.
[0038]
Since the jagged surface 93 is obliquely pointed in the Y2 direction, when the flexible printed wiring board 40 is moved in the Y2 direction, the flexible printed wiring board 40 bites into the jagged surface 93, and FIG. As shown in (2), the actuator 90 is moved in the Y2 direction. When the actuator 90 is moved in the Y2 direction, the tapered cam portion 91 enters the lower side of the upper jaw 71 from its narrow side, and the space between the actuator 90 and the contact portion 72a is reduced, and the flexible printed wiring is formed. The board 40 is sandwiched between the cam section 91 of the actuator 90 and the contact section 72a, the lower contact arm section 72 is bent in the Z2 direction, and the flexible printed wiring board 40 is firmly sandwiched and fixed, and You will not be able to pull.

[0040]
The operation of connecting the flexible printed wiring board 40 as described above is completed by the operation of inserting and pulling the flexible printed wiring board 40, and there is no need to operate the actuator 90, so that the operability is good.
[0041]
In the state shown in FIG. 8C, the operation unit 92 is pushed in the Y1 direction to move the actuator 90 in the Y1 direction, the distance between the actuator 90 and the contact unit 72a is widened, and the operation unit 92 is pushed. By pulling the flexible printed wiring board 40 in the Y2 direction as it is, the flexible printed wiring board 40 is pulled out and detached from the connector device 50A.
[0042]
The positional relationship between the upper jaw and the lower contact may be reversed, that is, the positional relationship between the lower jaw and the upper contact.
[0043]
【The invention's effect】
