2. Description of the Related Art FIG. 5 shows a conventional example of this type of connector. This connector has a flexible cable 140
The housing 120 includes a housing 120 inserted as indicated by a two- dot chain line, a plurality of contacts 130 fixedly held at a predetermined pitch in the housing 120, a slider 150 inserted into the contact 130, and the like. The contact 130 is a soldering portion which is connected to a branch piece 131 formed on the insertion side of the slider 150, a contact spring piece 132, and a land formed on the printed board when mounted on a printed board (not shown). 133.

[0003] The connection procedure of the flexible cable 140 in the conventional example having such a configuration is as follows.
First, as shown in FIG. 5A, the flexible cable 140 is inserted into the opening of the housing 120 which is opened to the left in the drawing until the tip of the flexible cable 140 contacts the inside of the opening.
To be served. Next, as shown in FIG. 5B, the slider 150 is pushed into the inside of the opening of the housing 120. Thereby, the flexible cable 140 is pushed into the inside of the opening of the housing 120 together with the slider 150, and the conductor pattern exposed at one end of the flexible cable 140 is connected to the contact spring piece 132 of the contact 130.

However, since the conventional flexible cable connector has a structure in which the slider is inserted horizontally and the flexible cable is pushed in, the operator checks whether the slider is completely inserted. It is difficult, and many have to rely on intuition. For this reason, the slider may not be completely inserted, and the fitting of the slider may be insufficient, which may result in poor contact between the flexible cable and the contact. In addition, it is difficult to push the slider into the housing while holding the flexible cable with one hand, and there is a problem that the workability is poor because the operator has to work with both hands.

[0005] Therefore, an object of the present invention is to provide a one-touch connector for a flexible cable in which it has been found that the flexible cable has been securely connected to the connector and this connection can be easily performed.

[0006]

One-touch connector for a flexible cable of the present invention SUMMARY OF THE INVENTION comprises a housing having a receiving portion for receiving a flexible cable, it juxtaposed in a predetermined direction in the housing, inserted the flexible to the receptacle includes a plurality of contacts in contact with the cable, and a pressing member for pressing the inserted said flexible cable to said receptacle to said contact, each contact, the conductor pattern of the flexible cable is pressed by the front Symbol pressing member In the one-touch connector for a flexible cable integrally having a contact spring piece that comes into contact with the pressing member, the pressing member pivots around the rotation axis parallel to the predetermined direction at the opening-side end of the receiving portion. The flexiv is provided when it is rotated to a predetermined position. The cable is adapted to be pressed to the contact, the further the pressing member said rotary shaft
A first engaging portion protruding outward with respect to the contact portion, wherein the contact extends in the receiving portion so as to face the contact spring piece.
A second engaging portion is formed integrally with the branching piece, and the second engaging portion is provided before the pressing member rotates to the predetermined position. The first engagement portion is engaged with the first engagement portion in one of the rotation directions to generate an operation feeling , and after the pressing member rotates to the predetermined position.
Is configured to engage with the first engagement portion in the other direction of the rotation direction to lock the pressing member at the predetermined position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A one-touch connector for a flexible cable according to an embodiment of the present invention will be described below with reference to FIGS. Referring to these drawings, the one-touch connector for a flexible cable (FPC) of the present embodiment includes a housing 2, a plurality of contacts 3,
It is configured to include the pressing member 5 and is used to connect the FPC 4.

The contact 3 is made of a conductive metal, is exposed at the tip of the upper surface of the FPC 4, and has the same pitch as a plurality of conductor patterns (not shown) arranged in a direction perpendicular to the plane of FIG. Are juxtaposed. Each contact 3 has a soldered portion 3 projecting outward from the housing 2.
3. It is composed of a lower branch piece 31 branched on the opposite side of the soldering portion 33, an upper contact spring piece 32, and the like. An engagement portion (second engagement portion) 31 a protruding upward is formed at the tip of the branch piece 31. At the tip of the contact spring piece 32, a contact portion 32a protruding downward is formed. The contact portion 32a contacts the conductor pattern of the FPC 4.

The housing 2 is made of an insulating synthetic resin, and a receiving portion 21 for receiving the FPC 4 is formed inside the housing 2.

The pressing member 5 is made of an insulating synthetic resin. As is apparent from FIGS. 2 to 4, an engaging portion (first engaging portion) 52 protruding downward is provided below the pressing member 5. Are formed. The pressing member 5 is located at the opening-side end of the receiving portion 21 of the housing 2. A rotating shaft 51 is provided on both sides of the pressing member 5.
Are rotatably supported at both ends of the housing 2. Due to this structure, the pressing member 5 is configured as shown in FIG.
It is configured to rotate as shown in FIG.

A connection procedure of the FPC 4 in the flexible cable one-touch connector of the present embodiment having the above configuration will be described. First, as shown in FIG. 2, with the pressing member 5 raised, the tip of the FPC 4 is inserted into the receiving portion 21 of the housing 2. Next, the pressing member 5 is
It is rotated downward in FIG. 2 about the axis C of the rotating shaft 51. Obviously, such a pivoting operation can be performed by an operator with one hand.

Here, during this rotation, the engaging portion 52 of the pressing member 5 comes into contact with the engaging portion 31a of the contact 3, and then, as shown in FIGS. get over. Further, by the engagement between the engaging portion 31a and the engaging portion 52, the operator can feel the operation feeling before the pressing member 5 presses the FPC 4 against the contact 3 to reach the state shown in FIG. 4, the pressing member 5 is locked in a state where the upper surface of the FPC 4 is pressed against the contact 3, thereby improving the contact between the conductor pattern on the upper surface of the FPC 4 and the contact portion 32a. And by the above operation feeling,
Since the worker can sense that the insertion work (rotation work) of the pressing member 5 has been completed, it is possible to prevent a contact failure between the contact portion of the contact and the conductor pattern of the FPC due to insufficient insertion of the slider as in the related art. Is done.

[0013]

As described above, the one-touch connector for a flexible cable according to the present invention has a feeling of operation when connecting a flexible cable. Therefore, it is possible to reliably connect the flexible cable to the connector by relying on this feeling. it can. In addition, the one-touch connector for a flexible cable of the present invention can perform a connection operation of a flexible cable with one hand with one touch, and is excellent in workability.
