  In a wire harness including a plurality of electric wires passing through the same path, there may be an electric wire to which a component such as a ferrite core is attached and an electric wire to which the component is not attached. In such a wire harness, the component may not be correctly attached to the electric wire to which the component is to be attached, or the component may be erroneously attached to the electric wire to which the component should not be attached.

  Therefore, the present invention has been made in view of the above-mentioned points, and regarding a plurality of electric wires passing through the same route, including an electric wire to which the component is attached and an electric wire to which the component is not attached, an error in attaching the component is made. It aims at providing the technique which can be suppressed.

  A wire harness according to a sixth aspect is the wire harness according to the second aspect, wherein the component is fixed to the first electric wire and marking is performed on the first electric wire. In the first electric wire, a tape is wound around a region including a fixed portion to which the component is fixed and is longer than the fixed portion in the extending direction of the first electric wire, or the region is a covering material. Covered with.

  According to the first to sixth aspects, either one of the first and second electric wires is marked, or different markings are made on both the first and second electric wires. The first electric wire to which the component is attached and the second electric wire to which the component is not attached can be identified. Therefore, it is possible to suppress mistakes in attaching components to the electric wires.

  In particular, according to the second aspect, since the marking on the electric wire is performed by winding a tape around the electric wire or covering the electric wire with a covering material, the first electric wire to which the component is attached and the component Can be visually identified by a simple method.

  FIG. 1 is a perspective view showing a wire harness 100 according to an embodiment. The wire harness 100 according to the present embodiment includes a plurality of electric wires 1a to 1c passing through the same route, and is arranged in a vehicle such as an automobile, for example. Several electric wire 1a-1c is arrange | positioned adjacent to each other.

  The electric wires 1a and 1b transmit, for example, an audio signal, and the electric wire 1c transmits, for example, a power supply voltage. The component 2 is attached to the electric wires 1a and 1b that transmit the audio signal, and the component 2 is not attached to the electric wire 1c that transmits the power supply voltage. The component 2 is, for example, a ferrite core. Hereinafter, the component 2 may be referred to as a “ferrite core 2”. Further, an electric wire to which a component is attached, such as the electric wires 1a and 1b, may be referred to as a “component-attached electric wire”, and an electric wire to which no component is attached, such as the electric wire 1c, may be referred to as a “component non-attached electric wire”. is there. By inserting the component mounting wires 1a and 1b into the through holes 2a of the ferrite core 2, the ferrite core 2 is mounted on the component mounting wires 1a and 1b.

  A connector 5 is attached to one end of the electric wires 1a to 1c, and a connector 6 is attached to the other end of the electric wires 1a to 1c. Terminals are attached to both ends of the electric wires 1a to 1b. Terminals attached to one ends of the electric wires 1 a to 1 c are inserted into the connector 5, and terminals attached to the other ends of the electric wires 1 a to 1 c are inserted into the connector 6. The electric wire 1a and the electric wire 1c are formed with the same kind of electric wire material. Accordingly, the electric wire 1a and the electric wire 1c have the same appearance color and the same thickness. Also, the electric wires 1a. 1c and the electric wire 1b are formed of different types of electric wire materials. In FIG. 1 and each figure described later, the same hatching is given to the electric wires 1a and 1c in order to show that the electric wires 1a and 1c are formed of the same kind of electric wire material.

  As described above, in the wire harness 100, the component-attached electric wire and the component non-attached electric wire pass through the same route (route between the connectors 5 and 6). Since the wire harness 100 includes the component-attached electric wire and the component non-attached electric wire, there is a possibility that an attachment error of the component 2 to the electric wire may occur. In particular, when the component-attached electric wire 1a and the component-non-attached electric wire 1c are formed of the same type of electric wire material as in the present embodiment, an error in attaching the component 2 to the electric wire is likely to occur. .

  Therefore, in the present embodiment, in order to identify the component-attached electric wire and the component non-attached electric wire, marking is performed on the electric wire. In the present embodiment, for example, the component-attached wires 1a and 1b and the component-unattached wire 1c are identified by winding the tape 3 together around the two component-attached wires 1a and 1b. The component 2 is attached to the component attachment wires 1a and 1b around which the tape 3 is wound. Thereby, the attachment mistake of the components 2 with respect to an electric wire can be suppressed.

  The tape 3 is made of, for example, PVC (polyvinyl chloride) as a base material, and is wound around portions excluding both ends in the component mounting wires 1a and 1b. Thus, in the component-attached electric wires 1a and 1b, the tape 3 is wound around an area longer than the length of the ferrite core 2 in the extending direction of the component-attached electric wires 1a and 1b. About the winding method of the tape 3 around the electric wires 1a and 1b, a rough winding in which the tape 3 is wound while leaving a gap may be employed, or a half wrap in which the tape 3 is partially overlapped may be employed. good.

  Next, the manufacturing method of the wire harness 100 shown by FIG. 1 is demonstrated. 2-4 is a figure for demonstrating the manufacturing method of the wire harness 100. FIG. As shown in FIG. 2, each of the plurality of electric wire materials is cut into a predetermined length to produce a plurality of electric wires 1 a to 1 c, and terminals 4 are attached to both ends of the plurality of electric wires 1 a to 1 c. Next, as shown in FIG. 3, the tape 3 is wound around the two electric wires 1a and 1b together. And as FIG. 4 shows, the electric wires 1a and 1b by which the tape 3 was wound are passed through the through-hole 2a of the ferrite core 2, and the ferrite core 2 is attached to the electric wires 1a and 1b. Thereafter, the terminal 4 at one end of the electric wires 1a to 1c is inserted into the connector 5 and the terminal 4 at the other end of the electric wires 1a to 1c is inserted into the connector 6, thereby completing the wire harness 100 shown in FIG.

  In the above example, the tape 3 is wound around the two electric wires 1a and 1b. However, the tape 3 may be individually wound around each of the electric wires 1a and 1b.

  Moreover, the marking method with respect to the electric wire for identifying the component attachment electric wires 1a and 1b and the component non-attachment electric wire 1c is not restricted to said example.

  For example, as shown in FIG. 5, instead of winding the tape 3 around the component-attached electric wires 1a and 1b, the tape 3 may be wound around the component-unattached electric wire 1c. In this case, the component 2 is attached to the electric wires 1a and 1b around which the tape 3 is not wound.

  Moreover, as FIG. 6 shows, while tape 3 is wound around component attachment electric wires 1a and 1b, tape 30 may be wound around component non-attachment electric wire 1c. Thus, when marking is performed on both the component-attached wires 1a and 1b and the component-unattached wire 1c, the component-attached wires 1a and 1b and the component-unattached wire 1c are identified in order to identify the component-attached wires 1a and 1b. It is necessary to perform different markings on the electric wires 1a and 1b and the component non-attached electric wires 1c. For example, by making the color of the tape 3 and the color of the tape 30 different, different markings are performed on the component-attached wires 1a and 1b and the component-unattached wire 1c. Further, by adopting rough winding as the winding method of the tape 3 and adopting half wrap as the winding method of the tape 30, the winding method of the tape 3 is different from the winding method of the tape 30. Different markings are made on 1a, 1b and the non-part-attached electric wire 1c.

  Moreover, instead of marking the electric wire by wrapping a tape around the electric wire, the electric wire may be marked by covering the electric wire with a covering material. FIG. 7 is a diagram illustrating a state in which the component-attached wires 1a and 1b are covered with the covering material 10 instead of winding the tape 3 around the component-attached wires 1a and 1b. As the covering material 10, for example, a corrugated tube or a braided tube formed of PET (polyethylene terephthalate) or the like can be used. In the example of FIG. 7, the covering material 10 covers portions excluding both ends of the component-attached electric wires 1 a and 1 b. Thereby, in the component attachment electric wires 1a and 1b, the area | region longer than the length of the component 2 in the extension direction of the said component attachment electric wires 1a and 1b is covered with the coating | covering material 10. FIG.

  In the example of FIG. 7, the component mounting wires 1 a and 1 b are covered together with the covering material 10, but each of the component mounting wires 1 a and 1 b may be individually covered with the covering material 10. Further, instead of covering the component-attached electric wires 1 a and 1 b with the covering material 10, the component non-attaching electric wire 1 c may be covered with the covering material 10. Further, the component-attached electric wires 1 a and 1 b may be covered with the covering material 10, and the component non-attached electric wire 1 c may be covered with a covering material different from the covering material 10. In this case, by changing the color of the covering material covering the component-attached electric wires 1a and 1b and the color of the covering material covering the component-unattached electric wire 1c, the component-attached electric wires 1a and 1b and the component non-attached electric wire 1c are changed. Different markings are made. Alternatively, the component-attached wires 1a and 1b are covered with a braided tube, the component non-attached wire 1c is covered with a corrugated tube, and the shape of the covering material covering the component-attached wires 1a and 1b and the component non-attached wire 1c are covered By making the shape of the material different, different markings are performed on the component-attached wires 1a and 1b and the component-unattached wire 1c.

  Further, when different markings are made on the component-attached wires 1a, 1b and the component-unattached wires 1c, the tape 3 is wound around the component-attached wires 1a, 1b to cover the component-unattached wires 1c with the covering material. 10 may be covered. Or you may cover the component attachment electric wires 1a and 1b with the coating | covering material 10, and may wind the tape 3 around the component non-attachment electric wire 1c.

  As described above, in the wire harness 100 including the component-attached wire and the component-unattached wire, either one of the component-attached wire and the component-unattached wire is marked, or both the component-attached wire and the component-unattached wire are marked. It is possible to distinguish between a component-attached electric wire and a component non-attached electric wire by marking differently. Therefore, it is possible to suppress an erroneous attachment of the component 2 to the electric wire, that is, the component 2 is not correctly attached to the component-attached electric wire or the component 2 is erroneously attached to the non-component-attached electric wire. Even if the component-attached wire 1a and the component-unattached wire 1c are formed of the same type of wire material as in the present embodiment, the component-attached wire 1a and the component-unattached wire 1c are clearly defined. Since it can identify, it can suppress that the component 2 is accidentally attached with respect to the component non-attached electric wire 1c.

  In addition, as in this embodiment, by marking the electric wire by wrapping the electric wire with a tape or by covering the electric wire with a covering material, the component-attached electric wire and the component non-attached electric wire can be easily obtained. Can be identified visually.

  Moreover, when the wire harness 100 includes a plurality of component mounting wires 1a and 1b as in the present embodiment, by winding the tape 3 around the plurality of component mounting wires 1a and 1b, or By covering the plurality of component mounting wires 1a and 1b together with the covering material 10, it is possible to prevent them from being separated when the component 2 is mounted on the plurality of component mounting wires 1a and 1b. Therefore, it becomes easy to attach the component 2 to the plurality of component mounting wires 1a and 1b.

  In the present embodiment, in the component-attached electric wire, is the tape 3 wound around an area longer than the length of the component 2 in the extending direction of the component-attached electric wire (see FIGS. 1 and 6) or Since the region is covered with the covering material 10 (see FIG. 7), it is possible to suppress the tape 3 or the covering material 10 from being hidden by the component 2 in a state where the component 2 is attached to the component mounting wire. Therefore, in the finished product of the wire harness 100, it can be visually confirmed whether the component 2 is correctly attached to the component-attached electric wire.

  In addition, when the wire harness 100 includes a plurality of component non-attached wires, and when marking the plurality of component non-attached wires, tape is attached to the plurality of component non-attached wires together. Alternatively, the plurality of non-part-attached electric wires may be wound together and covered with a covering material. FIG. 8 is a diagram illustrating a state where the tape 3 is wound around the two component non-attached wires 1c and 1d when the wire harness 100 includes the two component non-attached wires 1c and 1d. FIG. 9 is a diagram illustrating a state in which the two component non-attached wires 1c and 1d are covered with the covering material 10 together when the wire harness 100 includes the two component non-attached wires 1c and 1d.

  As described above, when the wire harness 100 includes a plurality of component non-attached wires, the tape 3 is wound around the plurality of component non-attached wires together, or the plurality of component non-attached wires are covered together. When the component 2 is attached to the component-attached electric wire, the plurality of component-non-attached electric wires can be prevented from being separated. When the component 2 is attached to the component-attached electric wire, if the plural non-component-attached electric wires are separated, the component 2 can be erroneously attached to a part of the plural non-component-attached electric wires. Therefore, it is possible to prevent the component 2 from being erroneously attached to a part of the plurality of component non-attached wires by suppressing the plurality of component non-attached wires from being separated. be able to.

  Further, the component 2 may be fixed to the component-attached electric wire by using a fixing member. In this case, the component mounting electric wire includes a fixed portion to which the component 2 is fixed, and the tape 3 is wound around a region longer than the fixed portion in the extending direction of the component mounting electric wire, or the region Is covered with a covering material.

  FIG. 10 includes a fixed portion 50 to which the component 2 is fixed in the component-attached wires 1a and 1b to which the component 2 is fixed, and is longer than the fixed portion 50 in the extending direction of the component-attached wires 1a and 1b. It is a figure which shows a mode that the tape 3 was wound around the marking area | region 60. FIG. In FIG. 10, the external shape of the component 2 fixed to the component attachment electric wires 1a and 1b is shown by a wavy line. Instead of winding the tape 3 around the marking area 60 of the component mounting wires 1a and 1b, the marking area 60 may be covered with a covering material.

  As described above, in the case where the component 2 is fixed to the component mounting wire, the component mounting wire includes a fixed portion to which the component 2 is fixed and is longer than the fixed portion in the extending direction of the component mounting wire. On the other hand, by wrapping the tape 3 or covering the area with a covering material, a marking is present immediately adjacent to the component 2 in a state where the component 2 is fixed to the component mounting wire. Therefore, in the finished product of the wire harness 100, it can be more easily confirmed by visual observation or the like whether the component 2 is correctly attached to the component-attached electric wire.
