BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat wire harness length adjusting structure, and more particularly, to a copper foil or a small-diameter wire such as an FPC (flexible printed circuit) or an FWC (flexible wire circuit). The length of a flexible flat wire harness having a configuration in which a conductor such as an electric wire is sandwiched by an insulating film can be adjusted.

Conventionally, as shown in FIGS. 13 and 14 (A) and (B), this type of flat wire harness has conductors 1 arranged at a required pitch covered with insulating films 2 and 3 on both sides. doing. FIG. 14A shows an FWC,
(B) is a case of FPC. The flat
When the power supply side and the electrical component side are connected using the wire harness 4, connectors 5 and 6 are attached to both ends in the length direction as shown in FIG.

[0003]

The length L1 of the flat wire harness 4 is equal to the length of the connector 5 connected to both ends.
It is necessary to correspond to the installation interval of 6 and connectors 5 and 6
When the distance between is long, the flat length L1 is long.
It is necessary to use a wire harness. On the other hand, if the distance between the connectors 5 and 6 is short, it is necessary to use a short overall length L1. That is, if the length L1 of the flat wire harness 4 is shorter than the distance between the connectors 5 and 6, it cannot be used naturally. On the other hand, if the length L1 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, and the extra portion drips and other parts And easy to interfere.

[0004] The flat wire harness 4 is manufactured continuously, and is usually sequentially cut to a predetermined length by a cutting machine. Therefore, the total length L1 of the flat wire harness 4 is the length set by the cutting machine. ing. By changing the cutting length of the cutting machine, the total length L1 is, for example, 250 cm or more.
Flat wire harnesses of different lengths are provided in several steps up to 50 cm.

However, the required length of the flat wire harness varies depending on the place of use, and the above-described problem occurs even if a plurality of types of pre-cut flat wire harnesses are selected and used. I do. Changing the cutting length of the flat wire harness to the required length according to the place of use solves the problem, but it is necessary to change the setting of the cutting length of the cutting machine each time,
Poor reality.

The present invention has been made in view of the above-mentioned problems, and has an advantage that the length of a flat wire harness can be expanded and contracted so that a flat wire harness having a fixed length is used in various places where required lengths are different. The purpose is to be able to do it.

[0007]

In order to achieve the above object, the present invention provides a pair of vertical frames which are arranged substantially parallel to each other with an interval larger than the width of the flat wire harness, and a pair of the vertical frames. A length adjusting member consisting of a plurality of horizontal frames arranged at intervals in the length direction of the vertical frame is provided, and one flat wire harness is connected to the horizontal frame of the length adjusting member. While winding and folding, insert the vertical frame from one end to the other end in the longitudinal direction, select the horizontal frame around which the flat wire harness is wound, and change the folding length to reduce the overall length of the flat wire harness. An object of the present invention is to provide a length adjusting structure of a flat wire harness which is adjustable.

The length adjusting member includes a pair of vertical frames and a rectangular outer frame in which the vertical frames are connected by a horizontal frame, and one or more horizontal frames are provided inside the outer frame at intervals. Have been placed.

It is preferable to provide a means capable of moving the horizontal frame in the longitudinal direction with respect to the vertical frame and stopping and holding the horizontal frame at a required position. In this case, even if two horizontal frames are provided,
The length can be adjusted steplessly.

Further, one end of the horizontal frame disposed inside the outer frame of the length adjusting member is fixed to one vertical frame, and the other end is provided with a gap without being connected to the other vertical frame. It is preferable that the flat wire harness can be easily inserted between the horizontal frames through the gap.

[0011]

In the flat wire harness length adjusting structure of the present invention, a flat wire harness having a fixed length is formed by inserting a single flat wire harness into the length adjusting member and folding the required length. It can be adjusted to the required length. In addition, the flat wire harness that has been folded back through the length adjusting member is wound around the horizontal frame and stretched, so that it does not hang down, and therefore does not interfere with other parts. Absent.
