Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an FPC (Flex).
ZIF (Zero I) capable of connecting a flexible thin plate-shaped circuit member (herein, collectively referred to as “FPC”) called an “Ible Printed Circuit” or a flat type flexible cable with low operation force.
The present invention relates to a connector type connector.

[0002]

2. Description of the Related Art Conventionally, a flat type flexible circuit board having a plurality of conductive patterns arranged on the surface of a flexible thin plate for 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 connecting end of the FPC as disclosed in, for example, Japanese Patent Publication No. 57-11105. In that case, a predetermined connection is obtained by inserting the FPC into the mating connector along with sliding contact.

Also, after fitting the mating connector,
A large number of connectors of this type have been developed (this type of connector is referred to as "ZIF-type connector") by driving the contacts of the mating connector or the FPC. For example, regarding the mechanical drive type, as an example, an electrical connector device disclosed in Japanese Patent Laid-Open No. 3-30273, and as another example, a modified high-density backplane connector disclosed in Japanese Patent Laid-Open No. 3-257775. As another example, as a connector using a shape memory alloy, there is a connector having high density and high signal integrity disclosed in JP-A-4-501338.

[0004]

As described above, when the FPC is connected to the mating connector, if the reinforcing material is simply fixed to the connecting end portion of the FPC, the FPC is repeatedly inserted and removed.
The PC is easily damaged, and if the conductive pattern is damaged, it may cause poor contact. Therefore,
It is difficult to apply when arranging FPCs in multiple rows to achieve high density contact.

On the other hand, the ZIF connector also has various problems. For example, in the case of the mechanical drive type connector of the above-mentioned one example and the other example, since the driving member is moved to bring the respective contacts into contact after fitting the respective parts, the structure of the connector main body becomes large and complicated. In addition to the drawbacks of being small and difficult to achieve high density, there is also a problem that the operating force becomes large when the number of contacts is large and the strength must be increased in consideration of the rigidity of the driving member and the holding member. In addition, in the case of the connector of another example, there is an advantage that the mechanism for operating from the outside is unnecessary and the mechanical structure is downsized, but the expensive shape memory alloy is used and Since a dedicated heating section and circuit for changing the state are required, the connector itself becomes expensive and it becomes a different mode with additional functions other than the original function, and when the temperature changes greatly depending on the usage environment. There is also a risk of malfunction.

[0006] By the way, in the case of such a connector, in addition to the time of inserting / removing the other substrate used for connection, two steps of operations are required and the number of operation steps for contacting each contact is increased, and a plurality of connectors are required. It is difficult to apply it to high-density contact when targeting FPC.

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

Another technical object of the present invention is to use a plurality of FPCs without taking time and effort to operate the contact portions of other boards with high density and stability, and with low operation force, to connect the mating connector. An object of the present invention is to provide a small-sized FPC connection connector that can be brought into contact with a contact.

BEST MODE FOR CARRYING OUT THE INVENTION The FPC connecting connector of the present invention will be described in detail below with reference to the drawings.

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

This FPC connector is used for the FPC3
Insulating elastic plates 4a, 4b as lever members, one end and the vicinity of which are fixed to the opposite surface of one end of a, 3b, that is, the rear surface, and the remaining portion extending apart from the rear surface,
The FPCs 3a, 3b are attached to the other ends of the elastic plates 4a, 4b.
Rotation for operation as a driving member for applying a force in the direction of approaching the back surface of the connector to bring the conductive pattern of the FPCs 3a, 3b into contact with the conductive contact 6a of the mating connector 6 by the lever action of the elastic plates 4a, 4b. The cam 5, the external insulator 2 that fits outside the insulator 6b of the mating connector 6, and the internal insulator that fits into the storage groove M of the external insulator 2 while holding the middle portion of the FPC 3a, 3b away from one end. Including 1 and. Here, the inner insulator 1 and the outer insulator 2 are collectively referred to as an insulator.

The inner insulator 1 and the outer insulator 2 are separate parts, but when the inner insulator 1 is fitted inside the outer insulator 2, they cooperate to form the hole H. The operation rotation cam 5 is inserted into the hole H from the side surface. The inserted operation rotating cam 5 is rotatably held in the hole H. The rotating cam 5 for operation is provided with elastic plates 4a and 4b when rotating.
Has a cam surface that pushes and moves the other end portion of the FCP 3a, 3b toward the rear surface. Each contact 6a has a groove or slit 6c of a slightly larger size so as to loosely receive the tip end portion of the FPC 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 inner insulator 1 holding the FPCs 3a and 3b is fitted into the housing groove M of the outer insulator 2. At that time, one ends of the FPCs 3a and 3b are inserted into the through groove 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 surface. At this time, the operating rotary cam 5 faces the elastic plates 4a and 4b as best shown in FIG.
The postures thereof are controlled so as not to push them toward the FCPs 3a and 3b.

Next, as shown in FIG. 3, the outer insulator 2 is fitted into the insulator 6b of the mating connector 6 so that the tip portions of the FPCs 3a and 3b to which the elastic plates 4a and 4b are fixed are the slits 6c of the contact 6a. To insert. In this state, the operation rotating cam 5 is rotated about 90 degrees. Then, the other ends of the elastic plates 4a and 4b are pressed by the cam surface of the operation rotation cam 5, and are pushed and moved toward the back surfaces of the FCPs 3a and 3b while the elastic plates 4a and 4b are bent. As a result, the elastic plates 4a and 4b become FCP3.
The elastic plate 4a, 4b has one end, that is, the other side, which acts as a lever member having a boundary between the portion fixed to a and 3b and the rest as a substantial fulcrum, and which will be described in detail later. The end portion of the connector 6 inserted into the slit 6c of the connector 6 is pressed against the contact 6a, and the surfaces of the FCPs 3a and 3b are contacted by the fulcrum described above.
Pressure contact with a. As a result, the conductive pattern P on the surfaces of the FCPs 3a and 3b becomes the contact 6a of the mating connector 6.
Are contacted in a one-to-one correspondence. That is, the FPCs 3a, 3
One end of b is connected to the mating connector 6.

When the FPCs 3a and 3b have a microstrip line structure with their back surfaces as ground planes, the elastic plates 4a and 4b are conductors and the portion indicated by reference numeral 6d is insulated from the contact 6a. By forming the contact as a separate component, it is possible to take a ground and obtain good transmission characteristics such as impedance matching.

Continuing with the description, this FPC connector has a pair of FPCs 3 each having one end side (a plurality of conductive patterns P are arranged on the surface of an insulating tape).
The middle parts of a and 3b are fixed to the insulator main body so that the back surfaces (of the insulating tape) face each other and the orientations of the one end sides thereof are aligned, and one end of each is attached to the back surface near the one end side. An internal insulator 1 in which insulating elastic plates 4a and 4b are fixed so as to be opposed to each other at a predetermined distance while matching the sides and forming the other end as a free end separated from the back surface (of the insulating tape). And a pair of FPC3
a and 3b, one end side of the elastic plates 4a and 4b, and one end side of the elastic plates 4a and 4b, which penetrate the external insulator 2 having a storage groove M for storing and holding the inner insulator 1, and the elastic plates 4a and 4a that face each other. 4b, which is a driving member for inserting the other ends of the FPCs 3b and 3b so that the other ends of the FPCs 3a and 3b are separated from each other and the front ends of the pair of FPCs 3a and 3b are separated from each other. It can be considered as a thing including. Incidentally, the internal insulator 1 here has a modularized structure.

Further, the inner insulator 1 and the outer insulator 2 are combined with the inner insulator 1 and the outer insulator 2 on the side surfaces of the inner insulator 1 and the outer insulator 2 in the direction perpendicular to the direction in which the FPCs 3a, 3b face each other.
Each notch is provided so that the hole H having a diameter larger than the predetermined distance is formed. Since most of the hole H is occupied by the notch formed on the outer insulator 2 side, the hole H may be provided only on the outer insulator 2 side. Further, the operation turning cam 5 has a size portion larger than a predetermined distance between the other ends of the elastic plates 4a and 4b facing each other. In addition, each elastic plate 4a,
On the surface of 4b, there are arranged grounding conductive patterns connected to the grounding conductive patterns of the FPCs 3a and 3b, respectively.

In the case of this FPC connection connector, the inner insulator 1 and the outer insulator 2 are combined, and the operation rotating cam 5 is inserted in the hole H between the other ends of the elastic plates 4a, 4b on the side of the narrow width thereof. In the state in which the FPC 3 is inserted as shown in FIG. 2, each FPC 3 is accommodated in the accommodation groove M of the external insulator 2 capable of accommodating the mating connector 6 as shown in FIG.
Since one end sides of a and 3b and one end sides of the elastic plates 4a and 4b are respectively projected, these respective parts can be fitted into the respective contacts 6a of the mating connector 6. Therefore, the mating connector 6 is housed in the housing groove M so that each FPC
After fitting one end side of 3a, 3b and one end side of each elastic plate 4a, 4b into each contact 6a, the operation rotation cam 5
Is rotated about 90 degrees so that the long side of the elastic plate 4a, 4b is sandwiched between the other ends of the elastic plates 4a, 4b. As shown in FIG. The pattern P is brought into contact with a plurality of contacts 6a arranged in parallel on the mating connector 6, respectively.

The contact at this time is performed based on the principle of leverage, and both ends of each elastic plate 4a, 4b contact the operation rotary cam 5 and the contact 6d, respectively, and in the directions of the thick arrows from these positions. In addition to receiving the drag forces F1 and F3, the fulcrum mentioned above presses the conductive pattern P on the surface of the FPCs 3a and 3b against the contact 6a and receives the drag force F2 in the direction of the thick arrow from this press contact point (however, in the figure, FPC
3a and elastic plate 4a only). Here, with respect to each elastic plate 4a, 4b, from the other end side and the contact point of the operation rotation cam 5, the tip end on one end side and the contact 6a.
Is L, the distance from the contact point of the other end side and the operation rotary cam 5 to the contact point of the one end side and the contact 6a is x, and the contact point of the one end side and the contact 6a From the location to the tip on one end side and the contact 6a
Assuming a relationship of L = x + y where y is the distance to the contact point, each drag force F1, F2, F3 and each distance L,
F1 × L = F due to the relation of rotational moment between x and y
The relationship of 2 × y, F1 × x = F3 × y holds. As a result, two relational expressions F1 = F2 · y / L and F1 = F3 · y / x are obtained with respect to the drag force F1 when the operation cam 5 is operated. These relational expressions suggest that by increasing x and L with respect to y, the drag forces F2 and F3 related to the required contact force can be obtained with a small drag force F1.
Therefore, the contact here is stably performed with a low operation force.

By the way, such contact is not caused by the operation turning cam 5, but is not provided with a notch portion for forming the hole H on the side surfaces of the inner insulator 1 and the outer insulator 2, and may be formed by another structure. Can be done. For example, as shown in FIG. 4 showing another embodiment of the present invention, a case where the insertion portion 8a formed integrally with the lid member 8 is used as a driving member will be described.

The lid member 8 is positioned by fitting it into the outer insulator 2 ', and when fitting, the insertion portion 8a is inserted into the through hole defined by the guide surface 1a' of the inner insulator 1 '. It is inserted, and the position is made movable 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 rear surfaces of the FPCs 3a and 3b when the position is moved.

Also with this configuration, as shown in FIG. 5, one side of each FPC 3a, 3b and each elastic plate 4a,
After fitting one end side of 4b to each contact 6a of the mating connector 6, the lid member 8 is pushed down to insert the insertion portion 8a between the other ends of the elastic plates 4a and 4b and push the other ends. When expanded, the plurality of conductive patterns P on one end side of each of the FPCs 3a and 3b become the mating connectors 6 as illustrated.
Are contacted with a plurality of contacts 6a arranged side by side. The contact at this time is also performed according to the leverage principle similar to that described with reference to FIG. Therefore, it is possible to obtain stable contact with a low operating force.

In the case of the above FPC connecting 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 one end. Another embodiment of a configuration in which a plurality of connecting portions arranged side by side on another substrate is indirectly contacted with each contact 6a of the mating connector 6 by using a segment shape having a side and the other end side Multi-row FPC
