[0041] [Description of embodiments of this disclosure]

[0042] The embodiments of this disclosure are first described by listing them.

[0043] For the wiring components of this disclosure, (1) It comprises: an electric wire; and a wire sheath that integrally covers the periphery of the electric wire, wherein multiple wire sheaths are provided at intervals along the axial direction of the electric wire, and each of the multiple wire sheaths has a direction identification part for identifying the orientation of the electric wire in the circumferential direction.

[0044] Based on the structure described in (1) above, the orientation of the sheaths in the circumferential direction of the wire can be easily determined by the direction recognition unit, thus making it easy to ensure that the orientation of each sheath in the circumferential direction of the wire is consistent. Furthermore, when a fixing member is installed on the wire, by setting the direction recognition unit as a marker, a structure can be created that ensures the orientation of the fixing members in the circumferential direction of the wire is consistent. Here, the respective orientation in the circumferential direction of the wire refers to the angular position of the direction recognition unit where the sheaths are positioned when the wire is viewed from the axial direction.

[0045] (2) In the wiring component described in (1) above, it is preferable to include a fixing member mounted on the cable sheath, wherein the direction identification portion is formed as a planar portion intersecting the circumferential direction on the outer peripheral surface of the cable sheath, and the fixing member has a base end portion capable of contacting the surface of the direction identification portion. According to the structure described in (2) above, the base end portion contacts the surface direction of the direction identification portion, thus making it easy to position the fixing member in the circumferential direction of the wire in a state that suppresses rotation.

[0046] (3) In the wiring component described in (2) above, preferably, the fixing member has a strap that extends from the base end and covers the outer peripheral surface of the cable sheath in the circumferential direction, and a protrusion that contacts the strap is provided on the outer peripheral surface of the cable sheath. According to the structure described in (3) above, the protrusion contacts the strap, increasing the contact area between the fixing member and the cable sheath, which increases the frictional resistance between the fixing member and the cable sheath, thus making it difficult for the strap to shift position relative to the cable sheath in the circumferential direction.

[0047] (4) In the wiring component described in (1) above, it is preferable that the outer shape of each of the sheaths is a regular polygonal shape that is the same as each other when viewed from the axial direction. According to the structure described in (4) above, since each sheath is a regular polygonal shape that is the same as each other, it is easier to grasp the angular position of each sheath in the circumferential direction of the wire.

[0048] (5) In the wiring component described in (4) above, it is preferable that each of the wire sheaths is provided with a marking portion, which distinguishes at least one side of the regular polygon shape from the other sides. According to the structure described in (5) above, at least one side of each side can be identified from the other sides in each wire sheath, so it is possible to perform the operation of installing the fixing component on the wire based on the side provided with the marking portion.

[0049] (6) In the wiring component described in (1) above, it is preferable to have a fixing member that integrally covers the periphery of the wire sheath. According to the structure described in (6) above, it is possible to make it difficult for the fixing member to shift relative to the orientation of the wire.

[0050] (7) In any of the wiring components described in (1) to (6) above, it is preferable that the circumferential angular position of the direction identification portion relative to the center of the wire is aligned at the same position in each of the wire sheaths. According to the structure described in (7) above, it is possible to lay wires inside the vehicle body without twisting the wires.

[0051] [Details of the embodiments of this disclosure]

[0052] The following description, with reference to the accompanying drawings, illustrates specific examples of this disclosure. It should be noted that this disclosure is not limited to these examples, as indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0053] <Implementation Method 1>

[0054] In Embodiment 1, the wiring member 10 is installed inside a vehicle body (not shown). It should be noted that the directional reference may not be the same as the directional reference when the wiring member 10 is installed in a vehicle (not shown) or similar object.

[0055] like Figure 1 As shown, the wiring component 10 includes an electrical wire 11, multiple sheaths 12, and multiple fixing components 13. The electrical wire 11 is a known component that surrounds a conductor 11A using a sheath 11B made of insulating synthetic resin. The conductor 11A is, for example, a single-core wire made of a single metal core, or a stranded wire composed of multiple bundled metal wires. The cross-sectional shape of the outer periphery of the sheath 11B is a circle concentric with the conductor 11A (see reference). Figure 4 A marking line 11C extending along the axial direction is attached to the outer peripheral surface covering 11B.

[0056] Multiple sheaths 12 are formed from synthetic resins such as elastomers, silicone rubber, etc. Each sheath 12 is formed in such a way that it integrally covers the periphery of the wire 11. Figure 2As shown, each sheath 12 is cylindrical, extending along the axial direction of the wire 11. Each sheath 12 is spaced at predetermined intervals along the axial direction of the wire 11 (see reference). Figure 1 Each sheath 12 is provided with a cylindrical main body 12A and an expanded diameter portion 12B provided at both ends of the main body 12A and expanding in the radial direction.

[0057] Each main body portion 12A has a direction identification portion 12C that identifies the orientation of the sheath 12 in the circumferential direction of the wire 11. For example, the direction identification portion 12C is a planar portion formed on the outer peripheral surface of the cylindrical main body portion 12A that intersects the circumferential direction of the wire 11 and is parallel to the axial direction of the wire 11. The direction identification portion 12C is formed between a pair of expanded diameter portions 12B. On the outer peripheral surface of the main body portion 12A, on both sides in the circumferential direction separated by the direction identification portion 12C, there are protrusions 12D that protrude radially and extend axially. That is, the direction identification portion 12C is surrounded by a pair of expanded diameter portions 12B and a pair of protrusions 12D.

[0058] When the cable sheath 12 is integrally molded onto the wire 11, the mold for molding the cable sheath 12 is opened, and the wire 11 is positioned on one of the molds, either the fixed side or the movable side. At this time, the marking line 11C on the wire 11 is aligned with the marking engraved on the mold. Then, the mold is closed, and the cable sheath 12 is formed. This operation is repeated at multiple different axial positions on the wire 11. Thus, multiple cable sheaths 12 can be installed at different axial positions on the wire 11. When the cable sheath 12 is integrally molded onto the wire 11, the circumferential angular position of the direction identification portion 12C in each cable sheath 12 relative to the center of the wire 11 is aligned at one point with reference to the marking line 11C of the wire 11 (see reference). Figure 1 ).

[0059] Multiple fixing components 13 have the function of fixing the wire 11 to an installation object in the vehicle body (not shown). For example... Figure 3 As shown, the fixing member 13 has a base end portion 13A and a locking portion 13B. The base end portion 13A has a square cylindrical portion 13C and a strap 13D extending from the square cylindrical portion 13C in a strip shape. The base end portion 13A has the same structure as a so-called known cable tie. A locking protrusion (not shown) is provided on the inner side of the square cylindrical portion 13C. On the surface of the strap 13D, a plurality of recesses (not shown) are formed in an extended direction. When the strap 13D is inserted into the square cylindrical portion 13C, the recesses of the strap 13D engage with the locking protrusion of the square cylindrical portion 13C. The strap 13D is movable relative to the square cylindrical portion 13C in the direction of insertion, but its movement is restricted in the direction of retraction.

[0060] A locking portion 13B protrudes from one of the walls constituting the square tube portion 13C. The locking portion 13B includes: a contact piece 13E, which abuts against one of the walls constituting the square tube portion 13C and extends in a disc-like shape; and a locking portion body 13F, which extends across the contact piece 13E towards a side opposite to the square tube portion 13C. The locking portion body 13F has a plurality of locking pieces 13G that extend obliquely toward the square tube portion 13C. The locking pieces 13G are configured to overlap in the direction in which the locking portion body 13F extends.

[0061] like Figure 4 As shown, when the fixing member 13 is installed on the cable sleeve 12, one of the wall portions constituting the square tube portion 13C is kept in contact with the direction recognition portion 12C, and the cable tie 13D is wound around the outer peripheral surface of the main body portion 12A of the cable sleeve 12 and inserted into the square tube portion 13C. At this time, the square tube portion 13C is in contact with the direction recognition portion 12C located between a pair of expanded diameter portions 12B and a pair of protrusions 12D. That is, the base end portion 13A can contact the direction recognition portion 12C.

[0062] Then, the strap 13D extending from the square tube portion 13C is stretched until it contacts the outer peripheral surface of the cable sheath 12. At this time, the protrusion 12D contacts the wall portion of the square tube portion 13C to which the strap 13D is connected. Then, the strap 13D extending from the square tube portion 13C is cut. In this way, the fixing member 13 is installed relative to each cable sheath 12. The fixing member 13 installed on each cable sheath 12 contacts the direction recognition portion 12C surface through one of the wall portions of the square tube portion 13C, so that the protruding direction of the locking portion 13B is aligned in the same direction (see reference). Figure 1 In other words, the angular positions of the circumferential locking portions 13B of the wire 11 are aligned at one point. The square tube portion 13C is restricted from disengaging from the direction identification portion 12C in the circumferential and axial directions of the wire 11 by a pair of expanding portions 12B and a pair of protrusions 12D.

[0063] As described above, the wiring member 10 of this embodiment 1 includes an electric wire 11 and a sheath 12 that integrally covers the periphery of the electric wire 11. Multiple sheaths 12 are provided at intervals along the axial direction of the electric wire 11. Each of the multiple sheaths 12 has a direction recognition portion 12C for recognizing the circumferential orientation of the electric wire 11.

[0064] According to this structure, the orientation of the sheaths 12 in the circumferential direction of the wire 11 can be easily determined using the direction recognition unit 12C, and the orientations of each sheath 12 in the circumferential direction of the wire 11 can be easily aligned. In addition, when the fixing member 13 is installed on the wire 11, by installing the fixing member 13 while marking it with the direction recognition unit 12C, a structure can be achieved in which the orientation of the fixing member 13 relative to the wire 11 is consistent.

[0065] The wiring member 10 includes a fixing member 13 that is mounted on the cable sheath 12. The direction identification portion 12C is a portion formed on the outer peripheral surface of the cable sheath 12 in a planar shape intersecting the circumferential direction. The fixing member 13 has a base end portion 13A that can contact the surface of the direction identification portion 12C. With this structure, the base end portion 13A contacts the surface of the direction identification portion 12C, thus facilitating the positioning of the fixing member 13 in the circumferential direction of the wire 11 in a state that suppresses rotation.

[0066] The fixing member 13 has a strap 13D extending from the base end 13A and covering the outer peripheral surface of the cable sheath 12 in the circumferential direction. A protrusion 12D is provided on the outer peripheral surface of the cable sheath 12, which contacts the strap 13D. According to this structure, the contact area between the protrusion 12D and the strap 13D increases, thereby increasing the frictional resistance between the fixing member 13 and the cable sheath 12. Therefore, it is difficult for the strap 13D to shift position relative to the cable sheath 12 in the circumferential direction.

[0067] The circumferential angular position of the direction identification portion 12C relative to the center of the wire 11 is aligned at the same position at each wire sleeve 12. According to this structure, installation can be performed with the fixing member 13 aligned with the wire 11 at an angular position, thereby allowing the wire 11 to be installed inside the vehicle body without twisting it.

[0068] <Implementation Method 2>

[0069] The orientation identification part 112C of the wiring member 20 in Embodiment 2 has a different shape than that in Embodiment 1. Everything else is the same as in Embodiment 1; the same reference numerals are used for the parts that are the same as in Embodiment 1, and repeated descriptions are omitted.

[0070] like Figure 5 As shown, the wiring component 20 includes an electrical wire 11, multiple sheaths 112, and multiple fixing components 13. The multiple sheaths 112 are formed from synthetic resins such as elastomers or silicone rubber. Each sheath 112 is integrally formed with the electrical wire 11.

[0071] like Figure 6 As shown, each sheath 112 is cylindrical, extending along the axial direction of the wire 11. Each sheath 112 is spaced at predetermined intervals along the axial direction of the wire 11 (see reference). Figure 5 Each sheath 112 is provided with a cylindrical main body 112A and an expanded diameter portion 12B provided at both ends of the main body 112A and radially expanded.

[0072] Each sheath 112 has a main body 112A that, when viewed from the axial direction, is an identical regular octagonal shape, a regular polygon. In other words, the portion of each sheath 112 sandwiched between a pair of expanded diameter portions 12B is formed by eight planes P. These planes P are direction identification portions 112C that identify the circumferential orientation of the wire 11. The direction identification portions 112C are formed between a pair of expanded diameter portions 12B.

[0073] Each directional identification section 112C is provided with a marking section 112E. For each marking section 112E, text, numbers, symbols, etc., are formed in a convex or concave shape relative to the directional identification section 112C. For example, the marking section 112E is pre-engraved in a mold for molding the cable sheath 112 and is transferred to the directional identification section 112C through the molding of the cable sheath 112. The marking sections 112E in each directional identification section 112C are different from each other. For example, in this embodiment, the letters A, B, C, D, E, F, G, and H are transferred to the directional identification section 112C as marking sections 112E. It should be noted that E, F, G, and H are not shown. Each directional identification section 112C can be distinguished from other directional identification sections 112C by the marking section 112E.

[0074] When the cable sheath 112 is integrally molded onto the wire 11, the wire 11 is positioned in the mold on one of the fixed or movable sides of the mold in the open state of the molded cable sheath 112. At this time, the marking line 11C in the wire 11 is aligned with the mark engraved in the mold. Then, the mold is closed to form the cable sheath 112. When the cable sheath 112 is integrally molded at different positions in the axial direction of the wire 11, the marking portion 112E of each cable sheath 112 is aligned at an angular position in the circumferential direction of the wire 11 with reference to the marking line 11C. For example, the angular position of the "A" of the marking portion 112E is aligned at a point with reference to the marking line 11C.

[0075] For example, such as Figure 7 As shown, when the fixing member 13 is installed on each wire sheath 112, the direction identification part 112C for surface contact of the square tube portion 13C of the fixing member 13 is indicated by the marking part 112E in each wire sheath 112. Therefore, the angular position of the fixing member 13 in the circumferential direction of the wire 11 can be set in 45-degree increments.

[0076] Each sheath 112 has the same regular octagonal shape when viewed from the axial direction of the wire 11. Because of this structure, it is easier to determine the angular position of each sheath in the circumferential direction of the wire 11, as each sheath 112 has the same regular octagonal shape.

[0077] Each cable sheath 112 is provided with a marking portion 112E, which distinguishes each side of the regular octagonal shape from the other sides. According to this structure, in each cable sheath 112, the direction identification portion 112C can be identified from the other direction identification portions 112C, so it is possible to perform the operation of installing the fixing member 13 on the wire 11 with the side provided with the marking portion 112E as a reference.

[0078] [Other embodiments of this disclosure]

[0079] It should be considered that the above-disclosed embodiments 1 and 2 are illustrative rather than restrictive in all respects.

[0080] Alternatively, unlike Embodiment 1 described above, it can be configured without protrusions.

[0081] Alternatively, unlike Embodiment 1 described above, multiple protrusions may be provided on the outer peripheral surface of the main body. In this case, when the cable tie is arranged to cover the outer peripheral surface of the cable sheath, the protrusions contact the inner peripheral surface of the cable tie.

[0082] Alternatively, unlike Embodiment 2 described above, the shape of the cable sleeve is not limited to the same regular octagon; it can be any regular polygon.

[0083] Alternatively, unlike Embodiment 2 described above, text, numbers, or symbols may be printed on the identification parts in each direction as marking parts, or a tape printed with text, numbers, or symbols may be pasted on.

[0084] Alternatively, unlike Embodiment 2 described above, a structure can be adopted in which the marking portion is provided only in a portion of the multiple direction identification portions. That is, a marking portion can also be provided in each protective sleeve, which distinguishes at least one side of each side of the regular polygonal shape from the other sides.

[0085] Alternatively, unlike embodiments 1 and 2 described above, the central portion of the direction recognition part may be bent and recessed toward the wire, or a pear-skin-shaped bump and groove may be provided.

[0086] Alternatively, unlike embodiments 1 and 2 described above, a structure can be adopted that includes a fixing member that integrally covers the periphery of the cable sheath. Specifically, the shape of the locking portion is pre-carved in a mold for molding the cable sheath, and the cable sheath and the locking portion are integrally molded. With this structure, the orientation of the fixing member can be prevented from shifting relative to the wire. In this case, the locking portion functions as a direction recognition part.

[0087] Furthermore, in this case, for the locking part (direction recognition part), the circumferential angular position of the direction recognition part relative to the center of the wire is aligned at the same position at each wire sleeve, so that the wire can be laid inside the vehicle body without twisting the wire.

[0088] Alternatively, unlike embodiments 1 and 2 described above, the direction recognition part can be formed on the outer peripheral surface of the cylindrical main body in a planar structure that intersects the circumferential direction of the wire.
