DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable used for wiring various electric devices.

[0002]

2. Description of the Related Art A flat cable is formed by punching a conductor foil to form a plurality of lines, and laminating the plurality of conductor foils with a synthetic resin film such as PET so as to integrate a plurality of wirings at once. It is configured to be able to perform. However, recently, the circuit design has become more complicated, and the connectors on the input side and the output side are not limited to one each, and the wiring in the circuit is considerably complicated. For this reason, it becomes necessary to use several types of flat cables, and the design, manufacture, installation, and the like become extremely complicated, resulting in an increase in man-hours, a price, and a decrease in efficiency.

For example, as in a first conventional example shown in FIG. 4, one side of a connector 1 has terminals a1, a2, a3, a
In the arrangement of 4, a5, the connector 2 on the other side has terminals b5, b
In the arrangement of 4, b1, b2, and b3, when it is necessary to connect the connectors 1 and 2 with the same numbers of the terminals a and b using the flat cable 3, a conductor foil is used in the flat cable circuit Fc. The lines of c1, c2 and c3 and the conductor foils c4 and c5 will intersect.

This is because, for example, when the main harness on the vehicle body side of an automobile is shared irrespective of the type of vehicle or the same type of vehicle, the harness in the door is different for each vehicle type or specification. Occurs. That is, terminal a4,
When the unit inside the door connected to a5 is a basic model or specification that is located below the terminals b1 to b3, another unit or specification places it above the terminals b1 to b3 for layout reasons inside the door. There are cases where it has to be done.

In such a case, it is difficult to wire the connectors 1 and 2 with one flat cable Fc.
At least two or more flat cables, that is, terminals a1,
A flat cable having a pattern connecting a2 and a3 to terminals b1, b2 and b3 and a flat cable having a pattern connecting terminals a4 and a5 and terminals b4 and b5 are required.

In the second conventional example shown in FIG.
One terminal is composed of a connector 3 having a terminal arrangement of terminals d1, d2, d3, d4, d5 and d6, and the other terminal is a terminal
Connector 4 composed of an array of e4 and e5 and terminals e3, e1, e2, e6
And a connector 5 having the above arrangement. Similarly, in this case, if wiring is performed using the flat cable 6, the lines cross in the flat cable circuit, so that wiring using a single flat cable is difficult.

That is, the connector 3 is connected to the connectors 4 and 5,
In order to connect with the flat cable 6, the flat cables connecting the terminals d5 and d6 of the connector 3 and the terminals e4 and d5 of the connector 4 respectively, and the terminals d1, d2 and
A flat cable is required to connect d6 to the terminals e3, e1, e2, and e6 of the connector 5, respectively.

[0008]

As described in the above conventional example, when lines cross in a flat cable circuit, it is difficult to wire with a single flat cable, and a plurality of flat cables are required. I do. Further, as the circuit becomes more complicated, the number of flat cables used increases, so that the number of design steps and the number of punching dies increase, and the problem that the flat cable manufacturing process and the mounting process become complicated is caused.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a flat cable in which the number of used flat cables can be reduced and the terminal arrangement order can be changed.

[0010]

In order to achieve the above object, a flat cable according to the present invention comprises a plurality of foil conductors arranged on a plane and covered with an insulating sheet. In the flat cable connecting the portion to the connector, a void is provided in the arrangement of the ends, and a part of the end located outside is folded back together with the insulating sheet and arranged in the void. The arrangement order of the end portions is changed, and these end portions are connected to the connector in a new arrangement order.

[0011]

In the flat cable having the above-described structure, the ends of the plurality of flat conductors of the flat cable are folded back so that the arrangement order of the conductor ends matches the terminal arrangement order of the connector.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a first diagram for conceptual explanation.
In this embodiment, the connector 15 is the same as the connector 1 shown in FIG. 4, and the terminals a1, a2, a3, a4, and a5 are arranged in this order from the top. On the other hand, the terminals of the connector 16 are terminals b5, b4, b
1, b2, b3 are arranged in this order, terminals a1 and b1, a2 and b
2,..., A5 and b5 need to be connected by the flat cable 17.

On the connector 15 side of the flat cable 17, the connector 1 is arranged in the order of conductor foils C1, C2, C3, C4 and C5.
5 are arranged at intervals of a1, a2,..., A5. However, on the connector 16 side, the conductor foils C4 and C5 are branched as flat cables 17 'with respect to the conductor foils C1, C2 and C3. The interval between the conductor foils C1, C2, and C3 and the interval between the conductor foils C4 and C5 match the terminal interval of the connector 16. When the flat cable 17 'is folded over the flat cable 17 around the bending line AA, the conductor foil C4,
C5 is arranged so as to intersect with the conductor foils C1, C2, C3 as shown by the dotted lines, so that the rearranged conductor foils are C5, C4, C1, C2,
C3 is in the order, and the interval between them coincides with the terminal interval of the connector 16.

Accordingly, the terminal arrangement is the same as the terminal arrangement of the connector 2 in FIG. 4, and it is possible to perform wiring with a desired terminal arrangement without crossing lines in one flat cable 17.

FIG. 2 shows a more specific second embodiment,
The terminals of the connectors 20 and 21 are conductive foils F1, F2,.
Is connected to the connector 23 via a flat cable 22 having The connector 20 is arranged in the order of the terminals d3, d1, d2, d6, the connector 21 is arranged in the order of the terminals d4, d5, and the connector 23 is arranged in the order of the terminals e1, e2, e3, e4, e5, e6. . The flat cable 22 is a connector 21
The flat cable 22 ″ is branched on the connector 23 side. The flat cable 22 on the connector 23 side is provided with conductor foils F1, F2 and F6, and the conductor foil F2 and the conductor foil An interval is provided between F6 so that three conductor foils can be inserted therein, and conductor foils F5, F4 and F3 are wired on the flat cable 22 ″.

Here, when the flat cable 22 ″ is folded around the refraction line BB as shown in FIG.
Conductor foils F3, F4, F5 are arranged between conductor foils F2 and F6.

Thus, on the connector 23 side,
Since the conductor foils F1, F2, F3, F4, F5, and F6 can be arranged in a line in this order, the terminals e1, e2, e3, e
Wiring can be performed in accordance with the arrangement of 4, e5, and e6.

[0018]

As described above, in the flat cable according to the present invention, even if one flat cable is used, the terminal arrangement is changed by folding the terminal portion and changing the terminal arrangement order. Can simplify the design and manufacturing processes, contributing to product cost reduction and rationalization.
