Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a flexible printed wiring cable (hereinafter referred to as "t").
The present invention relates to a connector connection FPC suitable for connecting a connector to a terminal end thereof.

[Prior art]

An example of a conventionally used FPC for connector connection will be explained with reference to the drawings.

Figure 1 is a cross-sectional view of the FPC, showing the insulating film l.

This figure shows a structure called a single-sided FPC, which has a printed wiring conductor 2 on one side.

Fig. 2 is a perspective view showing a pair of connectors for connecting the FPC to another circuit, and both the cable-side connector 3 and the receiver-side connector 40 that connect to the single-sided FPC have one row of connector terminals. It shows an example. However, in reality, from the point of view of cost and implementation efficiency,
At least the receiver is a side connector and the terminal arrangement is 2.
row connector (an example of which is shown as 4' in Figure 3)
is used as standard.

When the EPC is fitted to the above-mentioned connector side connector with two rows of terminal arrangement, the method of connecting the FPC and the cable side connector is as shown in Fig. 4 (f), separately. Prepared FPCs 5 and δ' are connected to cables with one row of terminal arrangement (l [method for connecting to connector 3, or
As shown in Fig. 40, a sub-FPC 6' is provided with electrical continuity through a wire 7 to the main FPC 6, and a cable-side connector 3 with a single row of terminals is connected to this FPC 6, 6'. A method was used to connect each.

However, the former method of preparing a separate FPC has the problem of increasing the number of parts and increasing the man-hours for parts management, and the latter method of connecting the main FP/C and the sub-FPC However, there is a problem in that the number of assembly steps for connection increases, and the connection reliability decreases due to the increase in the number of connection points. The purpose of this is to solve the above-mentioned problems in connecting the conventional FP/C and the cable side connector when the FPC is mated to the side connector with two rows of terminal arrangement. What?
The purpose of the present invention is to provide an FPC for connector connection.

[Summary of the invention]

The main point of the present invention is to provide an F-PC for connector connection.

so that each has approximately the same number of printed wiring conductors.

It is divided into two parts near the tip, and the two parts are shaped so that they can be overlapped with each other, and one connector connection FPC is connected through two cable connectors with a single row of terminal arrangement. The point is that the receiver having two rows of terminals is connected to the side connector.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 5 shows a connector connection FP that is an embodiment of the present invention.
FIG. 6 is a perspective view showing a state in which the FPC for connector connection is folded in order to fit into a side connector.

As clearly shown in FIG. 6, in this embodiment, two protruding parts 9 for connecting connectors are provided at the end of the connector connecting FPC 5 having a printed wiring conductor 2 on one side of the insulating film 10. ing. The part between the two overhanging parts 90 has a large cutout shape, and the connector connecting FPC 8 is folded into the shape shown in FIG. 6 around the fold line 10 at the center of the cutout part. Makes it easy to operate.

When fitting the connector connecting FPC 8 of this embodiment to a receiver side connector having two rows of terminal arrays, as shown in FIG. Using the folding line 10 in the direction substantially perpendicular to the end face of the connector as a fold, fold the connector connecting FPC 5 so that the connector 3 overlaps with the folding line 10, as shown in FIG.

According to this embodiment, the terminal arrangement of the two rows of receivers is in the side connector 4.
’, there is no need to connect between FPCs or prepare a separate FPC, which is effective in reducing assembly man-hours, improving connection reliability, and reducing parts management man-hours. be.

In the above embodiment, two protruding parts 9 are formed at the ends of the FPC 8 for connector connection in such a manner that the direction of the printed wiring conductor changes approximately at right angles, but the extending direction of the protruding parts 9 is The angles are not necessarily limited to those shown in the above embodiments. .

Note that the same applies to the cut shape and dimensions of the cut portion between the two overhang portions 90. The front and rear of the central folding line 10 of the upper notch may be processed into a serpentine shape, for example, to facilitate bending.

〔Effect of the invention〕

According to the present invention as described above, an FPC for connector connection
is divided into two near the tip so that each has approximately the same number of printed wiring conductors, and the two halves are shaped so that they can be overlapped with each other, and one FPC for connector connection is arranged in a terminal arrangement. Since the receiver with two rows of terminal arrangement is connected to the side connector via two cable connectors with one row of terminals, there is no increase in parts management man-hours or assembly man-hours. A receiver with two rows of terminals has the remarkable effect of realizing a connector connecting FPC that can be fitted into a side connector.
