Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat harness routed to an automobile, and more particularly, to a bent portion of a flat harness which is bent at the time of routing, and to easily identify a bent flat harness circuit arrangement. To make it possible.

[0002]

2. Description of the Related Art In recent years, as a wire harness routed to a place where external force does not act, such as a door, a roof, a trunk room, and a seat lower portion of an automobile, conductors that are parallelly wired at intervals are sandwiched between insulating sheets. Flat harnesses may be used. This flat harness has the advantages of having a small heat-dissipating property, a small wiring space, and a light weight, and tends to increase the number of wiring utilization points.

[0003] As shown in FIG.
Is arranged in such a manner that conductors 2 are arranged at intervals in the width direction, and both sides thereof are laminated as insulating strips 3 and 4 and locked as long strips, and connectors 5 and 6 are connected to both sides thereof. . FIG. 7 shows a state where the upper insulating resin sheet 3 is peeled off.

[0004] The flat harness is formed in a band shape having the same width as shown in FIG. 7 because it can be easily manufactured. However, at the time of wiring, it is necessary to bend along the wiring route. As shown in the figure, the flat harness 1 is bent at a required position so as to follow the wiring route.

[0005]

When the flat harness 1 is bent as shown in FIG. 8, the bending point has a predetermined dimension from the tip of the flat harness. For this reason, it is necessary to measure the dimension from the tip of the flat harness 1 and determine the bending point to perform the bending process.

Further, when the wire is bent, the arrangement of the conductors (A, B, C...) In the flat harness becomes difficult to understand. In addition, the arrangement of the conductors at both ends connected to the connector is very difficult to understand. Therefore, when connectors are connected to both ends of the flat harness after bending, misconnection tends to occur.

[0007] The present invention has been made in view of the above-mentioned problems, and a flat harness to be bent is provided.
It is an object to easily identify a bending position and an arrangement of conductors.

[0008]

In order to solve the above problems, the present invention relates to a flat harness in which conductors which are arranged in parallel in a width direction are laminated with an insulating resin sheet to form a strip having the same width. One of the width directions of the flat harness is defined as a reference side, and only on the reference side, identification portions are provided at a constant pitch over the entire length in the length direction of the flat harness, and the identification portion determines the bending position of the flat harness. Provided is a flat harness that enables identification and identification of an arrangement of conductors in a bent flat harness.

[0009] The identification section is formed of a colored identification mark. This identification mark is preferably attached to the same position on both sides of the flat harness. The identification mark is, for example, marked with a circle or the like by a paint of a color different from that of the flat harness.

As described above, if the identification portions are provided at a constant pitch over the entire length, for example, at a pitch of 50 mm, if the bending position is 300 mm from one end of the flat harness, the identification portion is counted at the sixth position. Can be easily identified as the bending position. In addition, since the identification portion is provided only on one reference side in the width direction of the flat harness, the reference side can be identified at a glance by the presence of the identification portion even if the flat harness is bent many times. It is possible to prevent misalignment with the connector without mistaking the arrangement form. Further, the inspection becomes easy.

[0011] It is preferable that the discriminating portion is constituted by a notch cut into a shallower edge than the reference edge. As described above, when the notch is the identification portion, it can be easily bent from the notch when bending at the position of the identification portion.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment. The flat harness 10 is formed by laminating plate-shaped conductors 11 made of copper foil, which are wired in parallel in the width direction at intervals, with insulating resin sheets 12 and 13 to form a strip having the same width. In the present embodiment, three conductors 11
Circuits A, B, and C are flat harnesses. In addition,
FIG. 1 shows a state where the upper insulating resin sheet 12 is peeled off.

The flat harness 10 has one end side in the width direction as a reference side S. Only the reference side S is spaced from the identification mark 15 at a constant pitch (50 mm in this embodiment) over the entire length of the flat harness 10. Is provided. This identification mark 15 is the flat harness 1
It consists of a round mark applied by applying a paint of a color different from 0, and the insulating resin sheets 12, 1 on both sides of the flat harness.
3 is attached to the same position on the front and back. The circuit C among the circuits A, B, and C is located on the reference side S, and therefore, the circuit C is located on the side where the identification mark 10 is attached.

When the identification mark 15 is attached to the flat harness 10 as described above, as shown in FIG. 3 (A), when bending is required, the bending position is dimensioned from the tip of the flat harness 10. Therefore, the bending position can be easily identified simply by counting the number of the identification marks 15 from one end of the flat harness.

Even in the bent state, since the identification mark 15 is provided on the reference side S where the circuit C is located, the circuit arrangement of the conductors 11 at both ends of the flat harness 10 can be seen at a glance at the position of the identification mark 15. Can be identified. Therefore,
When the connectors 5 and 6 are connected to both ends of the flat harness 10 after being bent, it is possible to prevent erroneous connection due to misalignment.

FIG. 3B shows the case where the flat harness 10 is bent twice, and FIG. 3C shows the case where the flat harness 10 is bent three times. The identification and the arrangement of the conductors of the flat harness 10 can be easily identified.

In the above embodiment, the identification marks 15 are provided on both the front and back surfaces of the flat harness 10, but may be provided only on the front surface.

FIG. 4 shows a second embodiment, in which a notch 20 which is cut shallowly at a constant pitch along the entire length of the reference side S of the flat harness 10 'is formed as an identification portion. The notch 20 is V-shaped in the present embodiment, but FIG.
As shown in FIG. 7, a slit-shaped notch 20 may be used, or (B)
The notch 20 of an arc shape shown in FIG. FIG. 4 shows a state in which the upper insulating resin sheet 12 ′ has been peeled off.

As described above, when the identification portion including the notch 20 is provided, the bending position can be easily identified by the number of the notches 20 from the tip of the flat harness 10 ', as in the first embodiment. In addition, it can be easily bent from the notch 20 at the time of bending, and the workability is good. Furthermore, notch 2
Since 0 is provided only on the reference side S, the reference side S can be determined at a glance by the position of the notch 20 even if it is bent a plurality of times,
The arrangement of the conductors 11 of the flat harness 10 'can be identified at a glance. In particular, the notch 20 is a flat harness 10 '.
The notch 20 is present even in the folded state since it appears on the front and back surfaces of the flat harness, so that the operation of attaching identification marks to both surfaces of the flat harness as in the first embodiment is not required.

[0020]

As is apparent from the above description, according to the present invention, one side in the width direction of the flat harness is set as the reference side, and the reference side has a constant pitch over the entire length in the length direction. Since the identification portion including the identification mark or the notch is provided, the bending position can be easily identified only by counting the number of the identification portion from the front end of the flat harness. In addition, since the identification part is provided only on the reference side, the arrangement of the conductors of the flat harness can be checked at a glance depending on the position of the identification part even if the flat harness is rolled up many times, and connectors are connected to both ends of the flat harness In this case, occurrence of erroneous coupling can be reliably prevented.

Further, when a notch is provided as an identification portion, the notch can be bent from the notch, and the bending workability can be improved.
