Insertion Force Connecto
r) connector, in particular, flexible printed circuit (FPC) connector.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Laid-Open No. 10-12331 discloses a connector for a flexible printed circuit (FPC) of this type.

However, in this conventional example, the assembling property is not taken into consideration, and the pressing member 33 and the support plate 26 are not combined.
The sheets must be combined and assembled in the housing. Therefore, it is difficult to apply this conventional example to an automatic assembly machine.

[0004]

However, in the above-mentioned conventional example, when the contact has a large number of cores and the base insulator or the operating element (slider) has a weak spring property, the operating element (slider) moves from the connector fitted state. It has the drawback of coming off and coming off. This is a controller (slider)
When the flexible printed circuit (FPC), that is, the cable is inserted and fitted by rotating and operating the lever to the release position, the reaction force from the contact causes a load or force on the holding portion between the base insulator and the operator (slider). This is because they are added and elastically displaced.

Further, if the spring property of the base insulator or the operator (slider) is strengthened, there is a drawback that the entire connector becomes large.

Therefore, the present invention was created in order to improve such conventional drawbacks, and the technical problem is that the number of cores of the contact is large, and the spring of the base insulator or the operator (slider) is used. It is to obtain a robust and small-sized flexible printed circuit (FPC) connector in which the manipulator (slider) does not come off from the base insulator when the connector is fitted to the connector even if the flexibility is weak, and the assembly property is taken into consideration.

[0007]

In order to solve the problems of the present invention, the following three means are adopted.

(1) A contact, a base insulator for fixedly holding the contact and receiving a flexible printed circuit, and a contact rotatably engaged with the contact between a closed position and an open position to press-contact the flexible printed circuit. A flexible printed circuit connector including a slider for holding the slider in a held state, comprising a pressing member having an arm portion and a main body, the slider having a shaft portion, and the base insulator having the slider. Is provided with a holding portion for receiving and holding the shaft portion of the bearing. The holding portion has a bearing recess for rotatably supporting the slider and an insertion groove for inserting the pressing member outside the bearing recess. The slider is formed in the vicinity of the bearing recess.

The arm part of the pressing member fits in the recess and is inserted in the insertion groove.
Inserted, a connector for a flexible printed circuit to said holding portion, wherein the this <br/> that prevents the elastic displacement.

(2) In the connector for flexible printed circuit according to (1), the pressing member is
The connector for a flexible printed circuit, further comprising a press-fitting portion protruding from the arm portion, the press-fitting portion being fixedly held as a result of being press-fitted into the insertion groove of the base insulator.

[0010]

[0011]

[Function] The base insulator is an operator (slider)
It has a holding part with. This holding portion is elastic and has an insertion groove on the outside and a bearing recess on the inside.

When the slider is assembled into the base insulator, the shaft portion of the slider slides smoothly on the slope of the guiding recess and then fits into the bearing recess with a click feeling. This allows the slider to be rotatably supported or pivotally engaged in the resilient bearing recess.

Next, the arm portion of the pressing member is guided and inserted into the insertion groove. At the same time, the press-fitting portion projecting from the arm portion of the pressing member is press-fitted into the insertion groove. The pressing member acts as a holddown for fixing / holding a holding portion of the base insulator with the operating element (slider). As a result, the spring property of the holding portion of the base insulator with the operating element (slider) is lost, and the holding portion of the bearing recess acts as a rigid member that is not elastically displaced. That is, the shaft portion of the manipulator (slider) acts so as not to come off from the bearing recess of the holding portion of the base insulator.

After the connector is assembled, the shaft portion of the slider is
The base insulator is disposed in the bearing recess as a rigid member, and the pivotally engaged state is reliably maintained. As a result, the slider held by the bearing recess serving as the rigid member is reliably held in the connector fitted state even when the reaction force of the contact is applied in the direction opposite to the fitting direction.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION A flexible printed circuit connector 21 according to an embodiment of the present invention will now be described with reference to FIGS.

A flexible printed circuit connector 21 according to an embodiment of the present invention includes a contact 22 having a pivot portion, a base insulator 23 for holding the contact 22 fixedly and receiving a flexible printed circuit (FPC), and a contact 22. A slider 27 is rotatably engaged with the pivotal portion between a closed position and an open position to hold the flexible printed circuit in a pressed state.

The flexible printed circuit connector 21 includes, as separate parts, an arm portion 29-3a, a press-fitting portion 29-2a, and a pressing member (hold down) 29a having a main body.

The slider 27 includes shaft portions 27-1a and 27-1.
b. Holding portions for receiving and holding the shaft portions 27-1a and 27-1b of the slider 27 are provided at both ends in the longitudinal direction of the base insulator 23, respectively.

A bearing recess 33a-1 for rotatably supporting (i.e., pivotally engaging) the slider 27 and a pressing member 29a outside the bearing recess 33a-1 are inserted into the holding portion of the base insulator 23. Insertion groove 31a
And are formed. A slider 27 is provided on the outer side in the vicinity of the bearing recess 33a-1.
A guiding recess 33a-2 having an inclined surface for easy reception when assembled in the.

When assembling the flexible printed circuit connector of the present invention, as shown in FIGS. 4 to 7, the slider 27 is incorporated in the base insulator 23 along the direction from the bottom to the top.

More specifically, by utilizing the elasticity (elasticity) of the holding portion 33, the shaft portion 27-1a slides smoothly on the slope of the guiding recessed portion 33a-2 of the base insulator 23. After that, the shaft portion 27-1a is inserted into the bearing recess 33a-1 and clicked with a "click" feeling (FIG. 8).

Next, the arm portion 29-3 of the pressing member 29a.
The press-fitting portion 29-2a protruding from a is guided and inserted into the insertion groove 31a and press-fitted. As a result, the holding portion of the base insulator 23 loses its elasticity and becomes rigid, and as a result, the base insulator 23 and the slider 27 are held.
Will be held securely.

[0023]

As described above, the connector for a flexible printed circuit according to the present invention includes the base insulator having the bearing recess for pivotally engaging the shaft portion of the operator (slider), and the outside of the bearing recess. An insertion groove for inserting the pressing member is formed, so that after assembly, a holding portion of the base insulator that does not elastically displace is formed, and the shaft portion does not come off from the bearing recess. Therefore, even if the number of contacts is large,
It is possible to strengthen the support portion of the base insulator, which receives a load when the connector is fitted, with the slider.

As a result, there is an effect that a slider for a flexible printed circuit can be obtained in which the slider does not come off and the assembling property is taken into consideration.

Moreover, it is possible to obtain a small and thin connector for a flexible printed circuit.
