DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FPC (Flex
ZIF (Zero I) that can connect a flexible thin plate-shaped circuit member (herein, these are collectively referred to as “FPC”) called an “ible printed circuit” or a flat-type flexible cable with a low operating force.
Insertion Force) type connector.

[0002]

2. Description of the Related Art Conventionally, a flat flexible circuit board, in which a plurality of conductive patterns are arranged on the surface of a flexible thin plate, with respect to a mating connector having a plurality of contacts arranged in parallel, that is, In order to connect the FPC, a reinforcing material is generally fixed to the connection end of the FPC as disclosed in, for example, Japanese Patent Publication No. 57-11105. In this case, a predetermined connection is obtained by inserting the FPC into the mating connector with sliding movement with the contact.

[0003] Also, after fitting to the mating connector,
A number of connectors of this type that obtain contact by driving the contacts of the mating connector or the FPC (this type of connector is referred to as a “ZIF connector” here) have been developed in large numbers. For example, with respect to a mechanical drive type, as an example, an electrical connector device disclosed in Japanese Patent Application Laid-Open No. Hei 3-30273, and as another example, a modified high-density backplane connector disclosed in Japanese Patent Application Laid-Open No. Hei 3-257775. As another example, a connector using a shape memory alloy includes a connector having high density and high signal integrity disclosed in JP-A-4-501338.

[0004]

As described above, when an FPC is connected to a mating connector, it is necessary to repeatedly attach and remove a reinforcing material to the connection end of the FPC, and to repeatedly insert and remove the FPC.
The PC is easily damaged, and if the conductive pattern is damaged, poor contact may be caused. Therefore,
This is difficult to apply when high density contact is to be achieved by arranging FPCs in multiple rows.

On the other hand, there are various problems in the ZIF connector. For example, in the case of the mechanical drive type connector of the above-described example and other examples, since the drive member is moved and the respective contacts are brought into contact after fitting the respective parts, the structure of the connector body becomes large and complicated. Besides, there is a problem that it is difficult to achieve high density with a small size, and there is also a problem that if the number of contacts is large, an operating force is increased and the strength must be increased in consideration of the rigidity of the driving member and the holding member. Further, in the case of another connector, there is an advantage that a mechanism for external operation is not required and the mechanical structure is reduced, but an expensive shape memory alloy is used, and A special heating section or circuit for changing the state is required, so the connector itself becomes expensive and has a different form with additional functions other than its original function. There is also a risk of malfunction.

[0006] In the case of such a connector, two steps are required separately from the insertion and removal of another board to be connected, and it takes time and effort to contact each contact. It is difficult to apply to high-density contact in the case of FPC.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a technical problem of the present invention is that a plurality of FPCs can be stably contacted with a contact of a mating connector with a high density and a low operating force. An object of the present invention is to provide a small FPC connection connector.

Another technical problem of the present invention is that a contact portion on another board can be stably formed at a high density with a low operating force by using a plurality of FPCs without troublesome operation. An object of the present invention is to provide a small-sized FPC connector that can contact a contact.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 and 2 are perspective views showing a basic configuration of an FPC connector according to an embodiment of the present invention before connection to a mating connector. This FPC
The connector for connection is a flat flexible circuit board (or a flat flexible cable) having a plurality of conductive patterns P disposed on one surface of a flexible thin plate, that is, a flat flexible cable, that is, FPCs 3a and 3b. One end is connected to the mating connector 6 provided on the printed circuit board 7. The conductive patterns P extend in parallel with each other at an equal pitch. The mating connector 6 has a plurality of contacts 6a held by insulators 6b in two rows. These contacts 6a are FC
The conductive patterns P3a and P3b are arranged at the same pitch as the conductive pattern P.

This FPC connector is an FPC3
Insulating elastic plates 4a and 4b as lever members, one end of which is fixed to the opposite surface of one end of each of the a and 3b, that is, one end and its vicinity are fixed to the back surface, and the remaining portion extends away from the back surface.
FPCs 3a, 3b are attached to the other ends of these elastic plates 4a, 4b.
Of the FPCs 3a, 3b by the leverage of the elastic plates 4a, 4b to make contact with the conductive contacts 6a of the mating connector 6 for operation. The cam 5, the external insulator 2 fitted outside the insulator 6 b of the mating connector 6, and the internal insulator fitted to the storage groove M of the external insulator 2 while holding a part of the FPCs 3 a and 3 b on the way away from one end. 1 is included. Here, the inner insulator 1 and the outer insulator 2 are simply referred to as an insulator.

The inner insulator 1 and the outer insulator 2 are separate components. When the inner insulator 1 is fitted inside the outer insulator 2, they cooperate to form a hole H. The operation rotary cam 5 is inserted into the hole H from the side. The inserted operation rotary cam 5 is rotatably held in the hole H. The operation rotary cam 5 is configured to rotate the elastic plates 4a, 4b during rotation.
Has a cam surface that pushes the other end of the FCP 3a, 3b in a direction approaching the rear surfaces thereof. Each contact 6a has a slightly larger groove or slit 6c so as to loosely receive the front end portion of the FPCs 3a, 3b to which the elastic plates 4a, 4b are fixed.

When connecting the FPCs 3a and 3b to the mating connector 6, first, the internal insulator 1 holding the FPCs 3a and 3b is fitted into the storage groove M of the external insulator 2. At this time, one ends of the FPCs 3a and 3b are inserted into the through-holes 2a and 2b at the bottom of the storage groove M. Then, the operation turning cam 5 is inserted into the hole H from the side. At this time, the operation rotating cam 5 faces the elastic plates 4a and 4b as best shown in FIG.
The posture is controlled so that they are not pushed in a direction approaching the FCPs 3a and 3b.

Next, as shown in FIG. 3, the outer insulator 2 is fitted to the insulator 6b of the mating connector 6, whereby the distal end portion of the FPCs 3a, 3b to which the elastic plates 4a, 4b are fixed is connected to the slit 6c of the contact 6a. Insert In this state, the operation turning cam 5 is turned by about 90 degrees. Then, the other end portions of the elastic plates 4a and 4b are pressed by the cam surface of the operation rotating cam 5, and are pushed and moved in a direction approaching the rear surfaces of the FCPs 3a and 3b with the bending of the elastic plates 4a and 4b. As a result, the elastic plates 4a and 4b
One of the elastic plates 4a and 4b, that is, one end of the elastic plates 4a and 4b, i.e., the other side, according to the principle of leverage, as will be described in detail later, and acts as a lever member having a boundary portion between the portion fixed to the a and 3b and the remaining portion as a substantial fulcrum. The end of the connector 6 inserted into the slit 6c of the contact 6a is pressed against the contact 6a, and the surfaces of the FCPs 3a and 3b are brought into contact with the contact 6a by the above-mentioned fulcrum.
a. As a result, the conductive patterns P on the surfaces of the FCPs 3a and 3b
Are contacted one by one. That is, the FPCs 3a, 3
b is connected to the mating connector 6 at one end.

When the FPCs 3a and 3b have a microstrip line configuration with the back surfaces as ground surfaces, the elastic plates 4a and 4b are formed of conductors, and the portions indicated by reference numeral 6d are insulated from the contacts 6a. By forming a contact as a separate component, a ground can be taken and good transmission characteristics such as impedance matching can be obtained.

Continuing the description, this FPC connector has a pair of FPCs 3 each having one end (a plurality of conductive patterns P are arranged on the surface of an insulating tape).
The middle portions of a and 3b are fixed to the insulator body such that the back surfaces (of the insulating tape) face each other and the ends of the middle portions are aligned with each other. An internal insulator 1 having insulating elastic plates 4a and 4b fixed to each other so as to be opposed to each other at a predetermined distance while being free ends spaced from the back surface (of the insulating tape). And a pair of FPC3

An operation rotating cam 5 which is a driving member inserted between the other ends of the FPCs 4b to expand the other ends and to deform the FPCs 3a, 3b in such a direction that the surface sides of the pair of FPCs 3a, 3b are separated from each other; Can be regarded as including. Incidentally, the internal insulator 1 here has a modularized configuration.

On the side surface of the internal insulator 1 and the external insulator 2 in the direction perpendicular to the direction in which the FPCs 3a and 3b face each other, the internal insulator 1 and the external insulator 2 are combined.
Notches are provided so as to form holes H having a diameter larger than the predetermined distance described above. Since most of the hole H is occupied by the cutout formed on the outer insulator 2 side, the hole H may be provided only on the outer insulator 2 side. Further, with respect to the operation rotary cam 5, each elastic plate 4a, 4b has a portion larger than a predetermined distance between the other ends facing each other. In addition, each elastic plate 4a,
On the surface of 4b, a grounding conductive pattern connected to the grounding conductive pattern of each FPC 3a, 3b is provided.

In the case of this FPC connector, the inner insulator 1 and the outer insulator 2 are combined, and the operation rotary cam 5 is sandwiched between the other ends of the elastic plates 4a and 4b in the hole H with the narrow dimension side thereof. When the FPC 3 is inserted into the storage groove M of the external insulator 2 in which the mating connector 6 can be stored as shown in FIG.
Since one end sides of the a and 3b and the one end sides of the elastic plates 4a and 4b are respectively protruded, these parts can be fitted to the respective contacts 6a of the mating connector 6. Then, the mating connector 6 is housed in the housing groove M and each FPC
After fitting one end side of 3a, 3b and one end side of each elastic plate 4a, 4b to each contact 6a,
Is rotated about 90 degrees so that the long dimension side is sandwiched between the other ends of the elastic plates 4a and 4b, as shown in FIG. 3, a plurality of conductive members on one end side of each of the FPCs 3a and 3b. The pattern P comes into contact with a plurality of contacts 6a arranged in parallel with the mating connector 6, respectively.

The contact at this time is performed by the principle of leverage, and both ends of each elastic plate 4a, 4b come into contact with the rotating cam 5 for operation and the contact 6d, respectively, and from these places in the direction of the thick arrow. The fulcrum presses the conductive pattern P on the surface of the FPCs 3a and 3b against the contact 6a, and receives the drag F2 in the direction of the thick arrow from the press-contact point (the FPC in the figure).
3a and only the elastic plate 4a are shown). Here, with respect to each of the elastic plates 4a and 4b, the tip of the other end and the contact 6a
The distance from the contact point of the other end and the operation rotary cam 5 to the middle part of the one end and the contact point of the contact 6a is x, and the middle part of the one end and the contact of the contact 6a. From one end to the other end and contact 6a
Assuming a relationship of L = x + y, where y is the distance to the contact point, each drag F1, F2, F3 and each distance L,
x, y, F1 × L = F
The relationship of 2 × y, F1 × x = F3 × y is established. Thereby, two relational expressions of F1 = F2 · y / L and F1 = F3 · y / x are obtained with respect to the drag F1 when the operation rotary cam 5 is operated. These relational expressions suggest that if x and L are increased with respect to y, the drags F2 and F3 relating to the necessary contact force can be obtained with a small drag F1.
Therefore, the contact here is performed stably with a low operating force.

Incidentally, such a contact is not made by the operation rotary cam 5, without providing a cutout for forming a hole H on the side surface of the inner insulator 1 and the outer insulator 2, and by another configuration. Can be done. For example, as shown in FIG. 4 showing another embodiment of the present invention, a case where an insertion portion 8a formed integrally with a lid member 8 is used as a driving member will be described.

The lid member 8 is positioned by being fitted to the outer insulator 2 '. At the time of the fitting, the insertion portion 8a is inserted into a through hole defined by the guide surface 1a' of the inner insulator 1 '. It is inserted and can be moved along the guide surface 1a '. The insertion portion 8a has a cam surface that pushes the other ends of the elastic plates 4a and 4b toward the back surfaces of the FPCs 3a and 3b when moving.

With this configuration, as shown in FIG. 5, one end side of each FPC 3a, 3b and each elastic plate 4a,
After one end of 4b is fitted to each contact 6a of the mating connector 6, the lid member 8 is pressed down to insert the insertion portion 8a between the other ends of the elastic plates 4a and 4b and push the other ends together. As shown in the figure, the plurality of conductive patterns P on one end side of each of the FPCs 3a and 3b
Is contacted with a plurality of contacts 6a arranged side by side. The contact at this time is also performed by the same principle of lever as described with reference to FIG. Therefore, stable contact can be obtained with a low operating force.

In the above-described FPC connection connector, one end side of the multi-row FPC is directly contacted with each contact 6a of the mating connector 6, but the multi-row FPC is connected to one end.
