DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.

[0010] [Embodiment] The wire harness WH according to this embodiment is, for example, a component in which a plurality of electric wires W used for power supply and signal communication are bundled together to connect various devices mounted on a vehicle, and the plurality of electric wires W are connected to the devices using connectors or the like. The wire harness WH according to this embodiment includes two electric wires W, a braided body 4, a shield shell 5, a fixing member 6, and an electric wire holding structure V including an electric wire holder 2 and a tape member 3. In addition to these, the wire harness WH may be configured to further include various other components such as a corrugated tube, a grommet, a fixture, and an electric junction box.

[0011] For convenience, in the following description, of the X, Y, and Z directions shown in the drawings, the X direction will be referred to as the "axial direction X" of the wire W, the Y direction will be referred to as the "width direction Y" of the wire holder 2, and the Z direction will be referred to as the "height direction Z" of the wire holder 2. The axial direction X, width direction Y, and height direction Z are perpendicular to one another. In particular, one of the axial directions X will be referred to as the "first axial direction X1," and the other as the "second axial direction X2." Unless otherwise specified, the directions used in the following description will be described as directions in a state in which the various parts are assembled together.

[0012] The electric wire W is, for example, an insulated electric wire in which a core wire formed by bundling a plurality of conductive metal wires is covered with an insulating covering. In this embodiment, the two electric wires W have the same outer diameter. Note that the electric wire W may also be a metal rod in which the outside of a conductive rod-shaped member is covered with an insulating covering.

[0013] The braided body 4 is formed by weaving a braided wire made of a conductive metal material. As shown in FIG. 1 , the braided body 4 is formed in a substantially cylindrical shape along the axial direction X and has a distal portion 41 disposed on the distal side in the axial direction X, a proximal portion 42 disposed on the proximal side in the axial direction X, and a reduced-diameter portion 43 disposed between the distal portion 41 and the proximal portion 42. The size (radial length) of the distal portion 41 is formed to be larger than the size (radial length) of the proximal portion 42. The size (radial length) of the reduced-diameter portion 43 gradually decreases from the distal side to the proximal side in the axial direction X. The braided body 4 is disposed outside the shield shell 5 and is assembled in a state in which the distal portion 41 covers the end of the shield shell 5, thereby allowing a portion of the electric wires W extending from the electric wire holder 2 to be accommodated inside.

[0014] The shield shell 5 is a member that is fastened to the body or the like with fastening members such as bolts when fixing the electric wire holder 2 shown in Fig. 1 to the body or the like of a vehicle. The shield shell 5 is formed from a conductive metal plate such as aluminum or an aluminum alloy. When the shield shell 5 is fastened to the body or the like of a vehicle, the shield shell 5 is electrically connected to the body or the like and is grounded (earthed).

[0015] The fixing member 6 is a shield ring made of a metal material, and is configured by a fastening member such as a metal tie or a crimp ring. As shown in Fig. 1, the fixing member 6 is formed in a substantially cylindrical shape along the axial direction X, and is crimped while being disposed outside the tip end portion 41 of the braided body 4, thereby tightening the tip end portion 41 and fixing it to the end of the shield shell 5.

[0016] The electric wire holding structure V according to this embodiment is applied to the wire harness WH shown in Fig. 1. The electric wire holding structure V includes an electric wire holder 2, which will be described later, and a tape member 3. The electric wire holding structure V holds two electric wires W, and can fix the electric wires W to the vehicle side by being engaged with a shield shell 5 fixed to the vehicle side.

[0017] The electric wire holder 2 is configured to include a pair of divided bodies 2A, 2B of the same shape, and holds two electric wires W in a state where the pair of divided bodies 2A, 2B are combined facing each other.

[0018] Each of the pair of divided bodies 2A, 2B has a main body 10, a wound portion 11, a notch portion 12, and a pair of wire groove portions 15. Each of the divided bodies 2A, 2B is integrally molded from an insulating resin material or the like.

[0019] The main body 10 constitutes the main component for accommodating and holding two electric wires W in each of the divided bodies 2A, 2B. As shown in FIG. 3, the main body 10 forms two electric wire insertion holes 2a adjacent in the width direction Y when the pair of divided bodies 2A, 2B are combined facing each other. The electric wire insertion holes 2a are formed so that the electric wire grooves 15 face each other when the pair of divided bodies 2A, 2B are combined facing each other. When the pair of divided bodies 2A, 2B are combined facing each other, the main body 10 engages with the mating main body 10.

[0020] The wound portion 11 extends from the main body 10 along one side of the axial direction X of the electric wire W (first axial direction X1) when the electric wire holder 2 is in a holding state in which the electric wire W is held, and is formed so as to cover the outer peripheral surface Wa of the electric wire W, and is a portion around which the tape member 3 is wound. The wound portion 11 has a J-shaped cross section when viewed from the axial direction X. The wound portion 11 is formed so that an inner surface 11b formed on the opposite side of the outer surface 11a faces the outer peripheral surface Wa of the electric wire W when the electric wire holder 2 is in a holding state in which the electric wire W is held. The wound portion 11 is composed of a flat portion 21 and a curved portion 22. The flat portion 21 and the curved portion 22 are integrally formed in the wound portion 11.

[0021] The outer surface 11a of the portion corresponding to the flat portion 21 is not curved but forms a flat surface. The flat portion 21 extends along the width direction Y and is formed in a flat plate shape. One end of the flat portion 21 in the width direction Y is connected to the curved portion 22. When the wire holder 2 is viewed from the height direction Z in the above-mentioned holding state, the other end of the flat portion 21 in the width direction Y is formed in a position that covers only one of the two electric wires W without covering the other side.

[0022] The curved surface portion 22 is formed such that the outer surface 11a of the portion corresponding to the curved surface portion 22 is not flat but curved. The curved surface portion 22 is formed along the outer peripheral surface Wa of one of the electric wires W when the electric wire holder 2 is in a holding state in which the electric wire W is held by the electric wire holder 2. When the electric wire holder 2 is viewed from the width direction Y in the above-mentioned holding state, the curved surface portion 22 is formed at a position where one end in the height direction Z covers approximately half of the electric wire W in the height direction Z (radial direction). In other words, when the electric wire holder 2 is viewed from the width direction Y in the above-mentioned holding state, the wound portion 11 is formed so as to cover a part of the outer peripheral surface Wa of the electric wire W on one of the sides.

[0023] The cutout portion 12 is a portion where the outer peripheral surface Wa of the electric wire W is exposed as an electric wire exposed surface Waa in the wound portion 11. When the main body 10 is viewed from the height direction Z, the cutout portion 12 is formed adjacent to the wound portion 11 in the width direction Y. When the pair of divided bodies 2A, 2B are combined facing each other and viewed from the height direction Z, the cutout portion 12 exposes the inner surface 11b of the wound portion 11 in one of the divided bodies (for example, divided body 2B in FIG. 3 ).

[0024] The wire grooves 15 are each formed to correspond to the wires W, and are recessed from the wire side toward the main body in the height direction Z of the main body 10. The wire grooves 15 are open at both ends in the axial direction X of the main body 10, and have a U-shaped or semicircular cross section as viewed from the axial direction X. The wire grooves 15 form wire insertion holes 2a facing each other in the height direction Z when the pair of segments 2A, 2B are assembled facing each other.

[0025] The tape member 3 is formed in a strip shape from an insulating resin material or the like, and is a member that is wound around the electric wire W from the electric wire holder 2 when the electric wire holder 2 holds the electric wire W, thereby restricting movement of the electric wire W in the axial direction X relative to the electric wire holder 2. As shown in Fig. 2 , the tape member 3 of this embodiment is wound in a continuous spiral shape without gaps, with parts of the tape member 3 overlapping each other.

[0026] As shown in FIG. 2, the tape member 3 has a first wound portion 31 and a second wound portion 32 in a wound state in which the tape member 3 is wound from the electric wire holder 2 to the electric wire W.

[0027] The first winding portion 31 is a portion wound around the outer surface 11a and the exposed wire surface Waa of the wound portion 11 in a wound state in which the tape member 3 is wound from the wire holder 2 around the electric wire W. The first winding portion 31 is located on the side of the second axial direction X2 with respect to the second winding portion 32, and is continuous with the second winding portion 32. The first winding portion 31 is a portion of the tape member 3 wound around the outer surface 11a and the exposed wire surface Waa of the wound portion 11 in the divided body B, and the outer surface 11a and the exposed wire surface Waa of the wound portion 11 in the divided body A. The first winding portion 31 includes an inner winding portion 33 and an outer winding portion 34.

[0028] As shown in Fig. 6, the inner winding portion 33 is a portion where the tape member 3 is wound around the outer surface 11a and the exposed electric wire surface Waa of the wound portion 11 of one of the segments 2B. In the inner winding portion 33, when the electric wires W are housed in the electric wire groove portion 15 of the segment B, the tape member 3 is wound around the outer surface 11a of the wound portion 11 of the segment B, the exposed electric wire surface Waa, and the outer peripheral surfaces Wa of the two electric wires W. The inner winding portion 33 corresponds to the winding start side of the first winding portion 31, and the tape member 3 is wound around the outer surface 11a of the wound portion 11 of the segment B, the exposed electric wire surface Waa, and the outer peripheral surfaces Wa of the two electric wires W. In the inner winding portion 33, the tape member 3 is wound around the outer surface 11a of the wound portion 11 of the segment B, the exposed electric wire surface Waa, and the outer peripheral surfaces Wa of the two electric wires W about 1 to 3 times in a direction perpendicular to the axial direction X.

[0029] The outer winding portion 34 is a portion where the tape member 3 is wound around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the other segment 2A. After the inner winding portion 33 is formed by the tape member 3, the outer winding portion 34 is formed by winding the tape member 3 around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the segment A in a state where the segment A is combined with the segment B. In the outer winding portion 34, the tape member 3 is wound around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the segment A about 1 to 3 times in a direction perpendicular to the axial direction X.

[0030] The second winding portion 32 is continuous with the first winding portion 31 and is wound down from the first winding portion 31 onto the outer peripheral surface Wa of the electric wire W located on one side in the axial direction X of the wound portion 11. In the second winding portion 32, the tape member 3 is wound continuously in a spiral shape without any gaps, with parts of the tape member 3 overlapping each other.

[0031] Next, a method for manufacturing the wire harness WH configured as described above (wire harness manufacturing method) will be described with reference to Figures 1, 2, 4, 5, 6, 7, and 8. In the following description, explanations will be given based on the flowchart in Figure 5, and other figures will be referred to as appropriate. The method for manufacturing the wire harness WH described below may be performed manually by an operator using various devices, equipment, jigs, etc., or may be performed automatically by various manufacturing devices.

[0032] The manufacturing method of the wire harness WH of this embodiment includes an accommodation step (step S1), a first tape winding step (step S2), an assembly step (step S3), a second tape winding step (step S4), and a third tape winding step (step S5), as shown in Fig. 5. Note that the manufacturing method of this wire harness WH will be described as being performed manually by a worker.

[0033] First, as an accommodation step, an assembly worker accommodates the electric wire W in the electric wire groove portion 15 of one of the divided bodies 2B of the electric wire holder 2 (step S1), as shown in Fig. 4. Here, the electric wire W is accommodated in each of the electric wire groove portions 15 of the divided body 2B.

[0034] Next, after the accommodation step, the assembly worker winds the tape member 3 around the divided body 2B and the electric wires W as a first tape winding step (step S2), as shown in Fig. 6. Here, the tape member 3 is wound as the inner winding portion 33 around the outer surface 11a of the wound portion 11 of one divided body 2B and the electric wire exposed surface Waa. In a state in which the electric wires W are accommodated in the electric wire groove portion 15 of the divided body B, the tape member 3 is wound around the outer surface 11a of the wound portion 11 of the divided body B, the electric wire exposed surface Waa, and the outer peripheral surfaces Wa of the two electric wires W, thereby easily fixing the two electric wires W to the divided body 2B.

[0035] Next, after the first tape winding step, the assembler assembles one divided body 2B and the other divided body 2A together as an assembly step, as shown in FIG. 7 (step S3).

[0036] Next, after the assembling process, the assembler winds the tape member 3 around the divided body 2B and the divided body 2A as a second tape winding process (step S4), as shown in Fig. 8. Here, the tape member 3 is wound as the outer winding portion 34 around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the other divided body 2A. After the inner winding portion 33 is formed by the tape member 3, the tape member 3 is wound around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the divided body A in a state where the divided body A is combined with the divided body B, whereby the tape member 3 can easily fix the divided body A to the divided body B in the accommodated state.

[0037] Next, after the second tape winding step, as shown in Fig. 2, the assembly worker winds and unwinds the tape member 3 around the wire holder 2 and the electric wire W as a third tape winding step, thereby completing the manufacturing method of the wire harness WH. Here, the tape member 3 is continuous with the first winding portion 31 and is wound and unwound from the first winding portion 31 onto the outer peripheral surface Wa of the electric wire W located on one side of the wound portion 11 in the axial direction X. Next, the assembly worker attaches the braided body 4, the shield shell 5, and the fixing member 6 to the wire holder 2, and then tightens the fixing member 6 to fix the braided body 4 to the shield shell 5, thereby manufacturing the wire harness WH shown in Fig. 1.

[0038] In the wire harness WH, the wire holding structure V, and the method for manufacturing the wire harness WH described above, the wire holder 2 includes a pair of divided bodies 2A, 2B, each of which has a wire groove 15 for accommodating an electric wire W, and which, when assembled face to face, holds the electric wire W by inserting it into the wire insertion hole 2a formed by the opposing wire grooves 15. With this configuration, when assembling the wire harness WH, two electric wires W can be easily assembled to the pair of divided bodies 2A, 2B. Furthermore, the divided bodies 2A, 2B have a wound portion 11 around which the tape member 3 is wound, and a cutout portion 12 in the wound portion 11 that exposes the outer circumferential surface Wa of the electric wire W as an electric wire exposed surface Waa. With this configuration, in the wire harness WH, the exposed wire surface Waa of the electric wires W and the outer surface 11a of the wound portion 11 on the wire holder 2 side are continuous in the circumferential direction of the wire holder 2, so compared to conventional wire harnesses, the contact area between the exposed wire surface Waa and the tape member 3 can be increased by winding the tape member 3 in the circumferential direction without winding it spirally. As a result, the wire harness WH, wire holding structure V, and wire harness WH manufacturing method described above can improve the holding force between the wire holder and the electric wires by winding the tape.

[0039] In the wire harness WH, the wire holding structure V, and the wire harness WH manufacturing method, the first winding portion 31 has an inner winding portion 33 formed by the tape member 3, which is wound around the outer surface 11a of the wound portion 11 of one of the segments 2B and the exposed electric wire surface Waa. With this configuration, the first winding portion 31 can easily fix the two electric wires W to the segment 2B by the tape member 3. In the wire harness WH, the wire holding structure V, and the wire harness WH manufacturing method, the first winding portion 31 has an outer winding portion 34 formed by the tape member 3, which is wound around the outer surface 33a of the inner winding portion 33 and the outer surface 11a of the wound portion 11 of the other segment 2A. With this configuration, the first winding portion 31 can easily fix the segment A to the segment B in a housed state with the electric wires W housed in the electric wire grooves 15 by the tape member 3.

[0040] In the above embodiment, the electric wire holder 2 is configured to hold two electric wires W of the same diameter, but is not limited to this. For example, the electric wire holder 2 may be configured to hold two electric wires W of different diameters, or may be configured to hold three or more electric wires W of the same diameter.

[0041] In the above embodiment, the pair of divided bodies 2A, 2B constituting the electric wire holder 2 have the same shape, but this is not limitative and they may have different shapes.

[0042] Furthermore, in the above embodiment, the notch 12 is formed in each of the pair of divided bodies 2A, 2B, but it may be formed in only one of them. [Explanation of symbols]
