Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on a printed circuit board and connects the circuit board with a flexible conductor such as a flexible flat cable (FFC), a flexible printed circuit (FPC), a conductive ink circuit (CIC) or the like. The present invention relates to a flexible conductor connector used for the.

[0002]

2. Description of the Related Art As a connector for connecting a flexible conductor such as FFC, FPC or CIC to a printed circuit board, conventionally, a direct insertion type connector shown in FIG. 8 and a ZIF shown in FIG. 9 have been used.
There was a system connector, a one-touch system connector shown in FIG.

In the direct insertion type connector of FIG. 8, a flexible conductor F reinforced by attaching a reinforcing plate E to an insertion / extraction opening C of a housing B in which a large number of contact pins A are mounted in a row is shown in FIG. When the conductor exposed surface G is inserted in such a manner that the conductor exposed surface G is on the contact pin side, the conductor wire of the flexible conductor F becomes the contact D of the contact pin A as shown in FIG.
They are pressed against each other to make electrical contact with each other.

The ZIF type connector of FIG. 9 is slidable in the front-rear direction (X-X direction in FIG. 9) in an insertion / extraction opening C on the front of a housing B in which a large number of contact pins A are mounted in a row. A slider H is attached, as shown in FIG. 9 (b).
As shown in FIG. 3, with the slider H pulled out forward, the flexible conductor F is inserted from the lower side of the slider H to the back of the insertion / extraction opening C so that the conductor exposed surface G is on the lower side. When the slider H is pushed into the housing B as shown in FIG. 6C, the conductor wire of the flexible conductor F is contacted with the contact pin A by the slider H.
It is pressed against the contact D of the both to electrically contact with each other.

In the one-touch type connector of FIG. 10, the contacts D of the contact pins A mounted in a row in the housing B are projected to the upper surface of the housing B, and a flexible plate E made of metal is attached to the upper surface. When the exposed conductor surface G of the conductor F is pressed, the reinforcing plate E spreads and press-fits the latches I provided at both ends of the housing B in the width direction, and the clamps I are clamped from the outside by the latch I. The conductor wire is electrically contacted with the contact D of the contact pin A.

[0006]

However, each of the above-mentioned connectors has the following problems. ． The direct insertion type connector of FIG. 8 has a simple component structure and is advantageous in that it is inexpensive, but has a high insertion / extraction force when inserting or extracting the flexible conductor F into / from the insertion / extraction port C. Is bad. In particular, the tendency becomes stronger as the number of conductor wires of the flexible conductor F increases. ． When the flexible conductor F is inserted or removed, the conductor surface is easily damaged, and the electrical performance is easily deteriorated. ． Since the flexible conductor F is simply inserted, when the inserted flexible conductor F is pulled, the flexibility may be displaced, resulting in poor electrical contact or the conductor F falling out.

[0007]. In the ZIF type connector of FIG. 9, the slider H is pulled out to insert or remove the flexible conductor F, so that the inserting / withdrawing force is small, but as shown in FIG. 9A, the flexible conductor F is horizontal and parallel to the substrate. The connector mounting position is limited to the edge of the board because it must be plugged into. This problem does not exist in the straight type connector in which the housing B is vertically mounted on the substrate among the ZIF type connectors. ． When the number of conductor wires of the flexible conductor F increases, the pushing force of the slider H increases, and workability is not necessarily good. ． In the case of a connector for a flexible conductor in which the pitch of the conductor wires is narrowed, the connector itself is also small and the slider H becomes small, which makes the operation difficult. ． Since the flexible conductor F is not mechanically held until the slider H is pushed and pressed against the contact D,
The flexible conductor F may not be completely inserted into the back or may be fitted obliquely, and a connection mistake is likely to occur. ． Since one hand is required to operate the slider, the flexible conductor F can only be fitted with one hand, which is difficult to operate.

[0008] The one-touch type connector of FIG. 10 is considerably excellent in terms of operability, disconnection prevention, incomplete fitting (contact shift) prevention, etc., but when the flexible conductor F is pushed and fitted to the contact pin side, Since a force equal to or greater than the reaction force by the contact pin A is required, a considerably large force is required for fitting when the flexible conductor F has a large number of conductor wires. ． The portion holding the flexible conductor F is the housing B.
Since there are only the latches I provided at both ends of FIG.
As shown in (a) and (b), the central portion of the flexible conductor F that receives the reaction force from the contact pin A warps upward and bends, and the contact pressure between the flexible conductor F and the contact pin A in the curved central portion is increased. It becomes smaller and the contact between them becomes insufficient.

The object of the present invention is to mount a flexible conductor,
Easy to remove and fit, one-handed fitting operation, flexible conductor can be fitted with low fitting force even without slider, the connector mounting position on the printed circuit board is not restricted, and the flexible conductor can be held securely. Therefore, the fitting position of the flexible conductor does not easily shift or come out, the conductor surface of the flexible conductor does not easily get damaged, and the central portion of the flexible conductor in the width direction does not warp due to the reaction force of the contact pin, which enables downsizing. Therefore, it is an object of the present invention to provide a flexible conductor connector that does not make it difficult to perform operations such as connecting and disconnecting a flexible conductor even if the connector is downsized.

In the flexible conductor connector according to the first aspect of the invention, since the housing receiving portion 3 and the contact receiving portion 30 are formed, the following various effects are obtained. ． Conductor line 13 at the insertion end 7 of the flexible conductor 5
Even if the contact pin 4 contacts the contact point 2 of the contact pin 2, the surface of the insertion end portion 7 is in contact with the housing receiving portion 3 and the contact receiving portion 30, so that the insertion end portion 7 is warped by the reaction force of the contact pin 2. And the contact between the conductor line 13 and the contact 4 is secured. ． When the flexible conductor 5 which is inserted into the insertion port 8 obliquely from above is rotated toward the contact pin 2 side, the insertion end 7 is inserted.
Since it rotates on the principle of leverage, the insertion end 7 can be rotated with a weak pressing force, and the flexible conductor 5 can be easily rotated with one hand.
The flexible conductor can be fitted with a low fitting force even without a slider. Further, even if the flexible conductor 5 has multiple cores, the increase in fitting force is small, and the insertion end portion 7 can be easily fitted to the connector with a weak force.

.. Since the insertion end 7 can be easily fitted to the connector with a weak force, the conductor surface of the flexible conductor 5 is less likely to be damaged. ． Since the flexible conductor 5 is inserted into the insertion port 8 obliquely from above, the flexible conductor 5 is surely inserted into the insertion port 8 and the insertion end 7 is rotated in that state, so that the flexible conductor 5 is insufficiently inserted. This eliminates the possibility of connection mistakes. ． Since the flexible conductor 5 is inserted into the insertion port 8 obliquely from above, the mounting position on the printed circuit board is not restricted. ． The flexible conductor 5 can be attached by a one-touch operation only by rotating the flexible conductor 5, and the flexible conductor 5 can be easily removed by expanding the latch 9 to the outside. Workability is improved. ． Since a slider is not required, the connector can be downsized,
It can also be used for high density printed circuit boards. In addition, operability does not deteriorate even with a small number of wires and a connector with a narrow pitch. ． The presence of the latch 9 makes it difficult for the flexible conductor 5 fitted to the connector to be displaced or accidentally pulled out.

In the flexible conductor connector according to the second aspect, since the housing receiving portion 3 is formed, the following various effects are obtained. ． Conductor line 13 at the insertion end 7 of the flexible conductor 5
Contacting the contact 4 of the contact pin 2, since the surface of the insertion end 7 is in contact with the housing receiving portion 3, the insertion end 7 does not warp due to the reaction force of the contact pin 2,
The contact between the conductor line 13 and the contact 4 is ensured. ． Among the effects of claim 1, there are the same effects as the effects of.

In the flexible conductor connector according to the third aspect, since the contact receiving portion 30 is formed, the following various effects can be obtained. ． Conductor line 13 at the insertion end 7 of the flexible conductor 5
Contacting the contact 4 of the contact pin 2, since the surface of the insertion end 7 is in contact with the contact receiving portion 30, the insertion end 7 does not warp due to the reaction force of the contact pin 2, The contact between the line 13 and the contact 4 is ensured. ． Among the effects of claim 1, there are the same effects as the effects of.

According to the flexible conductor connector of the fourth aspect, the fitting concave portion 19 and the pull-out preventing protrusion 20 are fitted to each other, so that the flexible conductor 5 is prevented from being pulled out carelessly even when pulled. The contact between the conductor line 13 of 5 and the contact 4 is reliably ensured.

According to the flexible conductor connector of the fifth aspect, since the latch 9 is provided with the reinforcing member 14,
The latch 9 is less likely to break or sag, and can withstand repeated attachment / detachment of the flexible conductor 5. Further, the creep deformation of the latch 9 can be prevented. Therefore,
It is also possible to prevent the contact force of the connector from being lowered due to creep deformation, prevent contact failure between the connector and the printed circuit board, and reduce the height and size of the connector.
