DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat wire harness with a connecting member and a method of adjusting the length of the flat wire harness, and more particularly to a flexible printed circuit (FPC) and a flexible wire circuit (FWC). ) And the like, and the length of a flexible flat wire harness having a configuration in which a conductor such as a copper foil or a thin wire is covered with an insulating film can be adjusted.

[0002]

Is the case of FPC. When connecting to the power supply side and the electrical component side using the flat wire harness 4 having the above configuration, connectors 5 and 6 are attached to both ends in the length direction as shown in FIG.

[0003]

The length L of the flat wire harness 4 is determined by the connectors 5, 6 connected to both ends.
When the distance between the connectors 5 and 6 is long, it is necessary to use a flat wire harness with a long overall length L, while the distance between the connectors 5 and 6 is small. If the length is short, it is necessary to use the one with a short overall length L. That is, if the length L of the flat wire harness 4 is shorter than the distance between the connectors 5 and 6, it cannot be used naturally. Conversely, if the length L of the flat wire harness 4 is too long than the distance between the connectors 5 and 6, an extra portion is generated in the flat wire harness,
There is also a danger that the surplus portion drips, interferes with other components, and causes a short circuit.

[0004] The flat wire harness 4 is manufactured continuously, and is usually cut in a predetermined length by a cutting machine. Therefore, the total length L of the flat wire harness 4 is the length set by the cutting machine. ing. In addition, by changing the cutting length by the cutting machine, the total length L is, for example, 250 cm to 50 cm.
Several types of flat wire harnesses are provided, differing in several steps up to cm.

[0005] However, the length of the flat wire harness required in accordance with the place of use is variously different, and the above-mentioned problem is not solved even if a plurality of types of pre-cut flat wire harnesses are selected and used. appear. Changing the cutting length of the flat wire harness to the required length according to the place of use solves the problem, but since the setting of the cutting length of the cutting machine needs to be changed each time, in reality, Near impossible.

The hinge portion 23 is fitted in the groove 20b of the flat wire harness 20, and the opposite ends are formed at both ends. The locking pieces 20a-1 are set so as to be positioned respectively.

In the third embodiment having the above structure, the flat wire harness 20 is folded back in the longitudinal direction, as in the first embodiment, and the groove 20b at the start position and the end position of the folded portion is opposed to each other. And

Next, a connecting member provided with an engaging portion composed of the pair of flat plates 21 and 22 is connected to a double overlapping flat plate.
It is located on both sides of the wire harness 20. Thereafter, the pin 21a of the flat plate 21 is fixed by penetrating through the locking hole 22a of the flat plate 22.

In the above-mentioned fixed state, the flat wire harness 20 which is doubly overlapped between the flat plates 21 and 22 is sandwiched, and the locking pieces 20a-1 of the flat wire harness 20 are provided at both ends of the annular portion 23. positioned. Therefore, even if an external force is applied to the flat wire harness 20, the engagement piece 20a-1 does not abut on the annular portion 23, and no displacement occurs.

[0030]

As is apparent from the above description, in the flat wire harness according to the present invention, the flat wire harness is folded in the length direction, and both end faces of the double wire harness are overlapped with each other. The flat wire harness can be adjusted in length because it is sandwiched and fixed by a pair of engaging flat members. Therefore, since the flat wire harness does not drop, it does not interfere with other parts.

A pin protruding from one flat plate of the connecting member penetrates the flat wire harness and the other flat plate,
Alternatively, since the locking pieces protruding from both side end faces of the flat wire harness are located on both side end faces of the flat plate, even if an external force is applied to the flat wire harness in the fixed state described above, the flat wire harness itself is not affected. It is securely fixed without any deviation.
