Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FF used for connecting a flexible flat cable to another connector.
The present invention relates to a C connector and a method for assembling the FFC connector, and more particularly to an FFC connector that uses a conductor of a flexible flat cable (hereinafter abbreviated as FFC) as an external connection terminal and a method for assembling the FFC connector.

[0002]

2. Description of the Related Art Generally, an FFC is a flexible strip-shaped thin conductor integrally molded with a sheet-shaped insulating coating, and is widely used not only in various electronic devices but also in automobile control systems. The conductor of this FFC has a thin strip shape and is easily deformed or broken by an external force, so that the end portion of the conductor is unsuitable for use as it is as an external connection terminal. Therefore, conventionally, there has been proposed what is disclosed as a "continuously molded terminal" disclosed in JP-A-3-17976.

In the cable terminal portion of the FFC 1 having the structure shown in FIG. 17, the conductor 3 exposed by peeling off the insulating coating 2 is ultrasonically welded or crimped to the metallic terminal member 4, and further soldered or crimped. The connection is made by the above method, and each terminal member 4 is sandwiched by the insulating members 5 and 6 which become the housing.

Further, the structure shown in FIG. 18 has the terminal member 1
Continuously molded terminals 13 configured by fixing 1 to a connecting member 12 made of synthetic resin or the like at equal intervals are used as connectors of the FFC 14. The conductor 15 of the terminal portion of the FFC 14 is connected to one end of the terminal member 11 by the same connection method as described above, and the connecting portion and the connecting member 12 are sandwiched by the insulating members 20 and 21 which serve as housings. Also,
Locking means 22 is provided on the insulating member 20, and the locking means 22 is inserted into a locking hole provided in the FFC 14 to insert the FFC 1.
4 is locked so that it cannot be pulled out. Furthermore,
The insulating member 20 is integrally formed with a convex portion 23 that fits into the groove portion 12a of the connecting member 12, and the continuous molding terminal 13 and the FF are formed.
The locking performance of C14 to the housing is good.

[0005]

However, the above-mentioned conventional connector structure has a common problem. That is, in the connector structure shown in FIG.
The conductor 3 of the FFC 1 must be connected to the terminal member 4 by ultrasonic welding, crimping, or the like. Therefore, the terminal member 4 is required, the number of parts is increased, and the connecting step is also essential. Moreover, even in the connector structure shown in FIG. 18, the conductor 15 of the FFC 14 must be connected to the terminal member 11. Therefore, in the same manner as described above, the number of parts is increased, and the connection step is also indispensable, which together contributes to an increase in production cost.

Further, since the strip-shaped thin conductors 3 and 15 are extended as they are to be connected to the terminal members 4 and 11, the pitch between the connection terminals 4 and 11 and the dimension in the width direction are different from each other.
The size in the width direction could not be reduced because it was determined by the number of 15 and the pitch. On the other hand, current electronic devices tend to be smaller and lighter, and especially the control system and the like mounted on an automobile have a limited space, so it is desirable to make the connector as small as possible. But,
In the above-mentioned conventional connector structure, the number of parts is large, and the size corresponds to the number and pitch of the conductors 3 and 15, so there is a limit to miniaturization.

It is an object of the present invention to provide an FFC connector and a method for assembling the FFC connector, which does not require the step of connecting the conductor of the FFC to a terminal and which enables miniaturization of the connection portion with the counterpart connector. .
