The opening 12 is provided on the opposite side of the center piece 11 with respect to both opposing pieces 12. Here, both opposing pieces 12 are formed so as to be able to bend when the end 12a is pressed in a direction orthogonal to the projecting direction.

An engaging portion 14 having a tapered portion 14a extends from the end portion 12a of each of the opposing pieces 12 to the inside of the U-shape 15 by integral molding with the opposing pieces 12, and an engaging recess 14b is formed.
Is provided by notching in a direction orthogonal to the projecting direction of both opposing pieces 12. Further, an engaging portion 16 is provided on each of the opposed pieces 12 along the projecting direction in the U-shaped interior 15. Further, a bottom portion 17 is provided in the U-shaped interior 15, and the cutout portions 17 are juxtaposed along both opposed pieces 12.
a, and a concave portion 17b having a substantially U-shaped cross section.

Reference numeral 2 denotes a contact which is a substantially U-shaped contact piece 21 made of elastic copper or copper alloy metal.
And an extension piece 22 extending from the contact piece 21 and formed in a substantially U-shape, and a connection piece 23 connected to the extension piece 22. The extension piece 22 is the concave portion 17b of the housing 1.
Is pressed into the housing 1 so that the contact piece 21 is
Of the housing 1, and are juxtaposed along the opposed pieces 12 in the U-shaped interior 15 of the housing 1.

Reference numeral 3 denotes a flexible printed circuit board. A circuit is formed on one or both sides by metal plating or the like using a flexible resin film, and cutouts 31 are formed on both sides.
A reinforcing plate 31 having a is disposed at one end.

The handling operation of this will be described with reference to FIGS. First, the connection piece 23 of the contact 2 is connected to another printed circuit board 4 by soldering. In this state, the flexible printed circuit board 3 having the reinforcing plate 31 disposed at one end thereof is inserted into the U-shaped interior 15 through the opening 13 of the housing 1 to engage with the central piece 11, and It comes into contact with the tapered portion 14a.

In this state, when the reinforcing plate 31 is pressed, the reinforcing plate 31 rotates around the tip end side as a fulcrum, and the tapered portion 14a is pressed, and the end portions 12a of both opposing pieces 12 bend in the direction perpendicular to the projecting direction. That is, the locking portion 14 moves in the orthogonal direction. Therefore, in a state where the flexible printed circuit board 3 is in contact with the contact piece 21 of the contact 2, both sides of the reinforcing plate 31 are fitted into the locking recesses 14 b and locked and held by the locking portions 14. At this time, in the housing 1, the bending of the opposing pieces 12 is eliminated and the housing 1 returns to the original state, and the engaging portion 16 is engaged with the notch 31 a of the reinforcing plate 31. In this way, the flexible printed circuit board 3 is mounted, and the flexible printed circuit board 3 and another printed circuit board 4 are connected via the contact 2 while facing each other.

In such a connector, as described above, the ends 12a of the opposing pieces 12 can be bent in a direction orthogonal to the projecting direction, and the U-shaped inner portion 1a extends from the ends 12a.
5 is provided, the reinforcing plate 3 is provided.
1 is disposed on the flexible printed circuit board 3.
3 and the central piece 1
Rotating with the tip end side engaged with 1 as a fulcrum, and in contact with the contact piece 21 of the contact 2, it is locked by the locking portion 14 movable in the orthogonal direction, and mounted using the slider portion. Unlike the prior art, it can be easily mounted simply by pressing, and without providing the locking portion 14 as a separate component,
By integrally extending from the end portions 12a of both opposing pieces 12, cost can be reduced.

Further, since the locking portion 14 is provided with the locking concave portion 14b cut out in a direction orthogonal to the projecting direction of the opposed pieces 12, the both sides of the reinforcing plate 31 fit into the locking concave portion 14b to lock. And both opposing pieces 1 of the housing 1
The end 12a of the second member is released from bending and returns to the original state,
The required space in the direction orthogonal to the projecting direction can be reduced.

Further, the reinforcing plate 31 has notches 3 on both sides.
In the case where the flexible printed circuit board 1a is provided, the engaging portion 16 that engages with the cutout portion 31a is provided in the housing 1, so that it is possible to prevent the flexible printed circuit board 3 from being pulled out even if it is pulled, and to be protruded. Positioning in a direction orthogonal to the direction can be accurately performed.

In this embodiment, the flexible printed circuit board 3 provided with the reinforcing plate 31 is mounted and connected to another printed circuit board 4, but as shown in FIG.
The printed circuit board 5 having a larger thickness than the flexible printed circuit board 3 may be mounted without disposing, and there is no limitation. In this case, screws conventionally required for fixing the facing printed circuit boards 4 and 5 can be eliminated.

When the flexible printed circuit board or printed circuit board on which the reinforcing plate is disposed is inserted into the U-shape from the opening and pressed, the contact piece of the contact rotates by pivoting on the tip end side engaged with the central piece. In the state of contact with the slider, it is locked by the central piece and the locking part movable in the orthogonal direction, unlike the conventional mounting using the slider part, it can be easily mounted just by pressing, and the locking part is separated. Without being provided as a component, the components can be integrally extended from the ends of both opposing pieces to reduce costs.

According to the second aspect, in addition to the effect of the first aspect, since the locking portion is provided with a locking recess cut out in a direction orthogonal to the projecting direction of the both opposing pieces, the reinforcing plate or the reinforcing plate is provided. Both sides of the printed circuit board fit into the locking recess and are locked, and the ends of both opposing pieces of the housing are released from bending and return to the original state, so that necessary space in the direction orthogonal to the projecting direction is reduced. Can be smaller.

According to the third aspect, in addition to the effects of the first or second aspect, if the reinforcing plate or the printed circuit board has notches on both sides, the reinforcing plate or the printed circuit board is connected to the notches. Since the mating engaging portion is provided in the housing, it is possible to prevent the flexible printed circuit board or the printed circuit board from being pulled out even if pulled, and to accurately perform positioning in the direction orthogonal to the projecting direction.
