[0014] Hereinafter, a wire harness assembly 1 according to an embodiment will be described in detail with reference to the accompanying drawings. Note that the dimensional ratios in the drawings are exaggerated for ease of explanation and may be different from the actual ratios.

[0015] Reference will be made to Figures 1 to 2 describe the first embodiment.

[0016] As Figure 1 shown, the wire harness assembly 1 according to the first embodiment is applied to, for example, a wire harness 3 that electrically connects an electrical component (not shown) to a device or electrically connects a device to a device. The electrical component is, for example, a power source mounted on a vehicle. The wire harness 3 is arranged in a predetermined shape inside an assembly component 5 integrally assembled therewith. The wire harness assembly 1 is assembled to a target component (not shown), such as a door trim of a vehicle.

[0017] As Figure 1 and Figure 2 shown, the wire harness assembly 1 includes a wire harness 3 and an assembly component 5.

[0018] As Figure 1 and Figure 2 shown, the wire harness 3 includes electric wires 7 and connectors 9.

[0019] The electric wires 7 include, for example, coated electric wires in which the outer periphery of a core wire made of a conductive material is coated with an insulating sheath, and a plurality of (four in this embodiment) electric wires 7 are used. The electric wires 7 can be flat cables in which the outer peripheries of a plurality of core wires are coated with an insulating sheath in a state where the plurality of core wires are arranged in parallel. The plurality of electric wires 7 are arranged such that both end portions thereof protrude from the assembly component 5. The plurality of electric wires 7 are arranged such that the end portions on one end side are gathered at one position and the end portions on the other end side branch.

[0020] The connectors 9 include, for example, a housing (not shown) made of an insulating material such as synthetic resin and terminals (not shown) made of a conductive material. The housing can be fitted to a mating housing (not shown) of a mating connector (not shown) electrically connected to an electrical component mounted on a vehicle. The terminals are electrically connected to the end portions of the electric wires 7 and are accommodated in the housing. By fitting the housing to the mating housing, the terminals are electrically connected to mating terminals (not shown) accommodated in the mating housing. A plurality of (five in this embodiment) connectors 9 are used to correspond to the end portions of the plurality of electric wires 7 protruding from the assembly component 5.

[0021] As Figure 1 and 2 shown, the assembled component 5 includes a base portion 11 and a cover portion 13.

[0022] The base portion 11 is made of a foam such as polyurethane or a non-woven fabric such as polypropylene fiber, polyethylene terephthalate fiber, polyester-based fiber, etc., and has sound insulation and heat insulation properties. The base portion 11 is formed in a sheet shape, and its size is set such that the base portion 11 is disposed within the range of the target component, and is assembled to the target component by a fixing method (not shown) such as press fitting. On one surface side of the base portion 11, a plurality of (four in this embodiment) electric wires 7 of the wire harness 3 are arranged in a predetermined shape. The ends of the plurality of electric wires 7 protrude a predetermined length from the outer edge of the base portion 11, each electric wire 7 is disposed on the base portion 11, and the connector 9 is disposed outside the base portion 11.

[0023] The cover portion 13 is made of a film such as vinyl chloride or polyethylene, or a closed-cell foam or open-cell foam such as polyethylene, polypropylene, polystyrene, elastomer, etc., and has sound insulation and heat insulation properties. The cover portion 13 is formed in a sheet shape, and its size is set to be equal to the size of the base portion 11 such that the cover portion 13 is disposed within the range of the target component, and its thickness is set to be smaller than the thickness of the base portion 11. A bonding portion 15 formed by an adhesive is provided on the surface of the cover portion 13 facing the base portion 11. The cover portion 13 is attached to one surface side of the base portion 11 in such a manner that the plurality of electric wires 7 are sandwiched between the cover portion 13 and the base portion 11 through the bonding portion 15. In a state where the cover portion 13 is attached to the base portion 11, the plurality of electric wires 7 arranged in a predetermined shape are held between the base portion 11 and the cover portion 13. Therefore, the assembled component 5 can protect the electric wires 7 of the wire harness 3 and maintain the arranged shape of the electric wires 7.

[0024] In a state where the wire harness assembly 1 is assembled to the target component, the connector 9 exposed from the assembled component 5 is fitted to the mating connector. At this time, since the electric wire 7 protrudes a predetermined length from the outer edge of the assembled component 5, the connector 9 can move freely, making it easy to fit the connector 9 to the mating connector. By fitting the connector 9 to the mating connector, the electrical components are electrically connected to each other.

[0025] Here, in a conventional wire harness assembly, the bonding portion for attaching the base portion and the cover portion is provided on the entire surface of the assembled component. Therefore, a large amount of adhesive is used for the bonding portion, resulting in a high cost.

[0026] On the other hand, in this embodiment, the bonding portion 15 includes a bonding portion 17 along the line. A non-bonding region 19 where the bonding portion 15 is not arranged is provided between the base portion 11 and the cover portion 13.

[0027] The along-wire fitting portion 17 is disposed between the base portion 11 and the cover portion 13 of the assembly member 5 along the electric wire 7 disposed inside the assembly member 5. For example, the along-wire fitting portion 17 is formed on the base portion 11 by disposing a shielding sheet (not shown) having the same shape as the base portion 11 and having through holes formed in a portion where the along-wire fitting portion 17 is to be formed on one surface side of the base portion 11, and spraying an adhesive. Note that the along-wire fitting portion 17 may also be formed on the cover portion 13. The along-wire fitting portion 17 fits the portions of the base portion 11 and the cover portion 13 where the electric wire 7 is disposed, so as to integrally attach the base portion 11 and the cover portion 13. By providing the along-wire fitting portion 17 in the portion of the assembly member 5 where the electric wire 7 is disposed, the base portion 11 and the cover portion 13 can be integrated, and the portion of the assembly member 5 where the electric wire 7 is not disposed can be a non-fitting region 19 where the fitting portion 15 is not disposed. Therefore, the amount of adhesive used can be reduced by the same amount as the non-fitting region 19 of the assembly member 5 where the electric wire 7 is not disposed. In addition, by disposing the along-wire fitting portion 17 along the electric wire 7, the electric wire 7 disposed in the along-wire fitting portion 17 can be fitted, and the disposed shape of the electric wire 7 can be stably maintained. In addition, by disposing the along-wire fitting portion 17 along the electric wire 7, the along-wire fitting portion 17 can be used as a guide for disposing the electric wire 7, and the assemblability can be improved.

[0028] The wire harness assembly 1 according to the present embodiment includes a wire harness 3 and an assembly member 5. The wire harness 3 includes an electric wire 7 and a connector 9 electrically connected to an end portion of the electric wire 7, and the wire harness 3 is disposed in the assembly member 5. The assembly member 5 includes a base portion 11 and a cover portion 13 attached to the base portion 11 through a fitting portion 15. The fitting portion 15 includes an along-wire fitting portion 17 disposed along the electric wire 7. A non-fitting region 19 where the fitting portion 15 is not disposed is provided between the base portion 11 and the cover portion 13.

[0029] By providing the along-wire fitting portion 17 in the fitting portion 15, the base portion 11 and the cover portion 13 can be integrated, and the portion of the assembly member 5 where the electric wire 7 is not disposed can be a non-fitting region 19 where the fitting portion 15 is not disposed. Therefore, the amount of adhesive used can be reduced by the same amount as the non-fitting region 19 of the assembly member 5 where the electric wire 7 is not disposed. In addition, by disposing the along-wire fitting portion 17 along the electric wire 7, the electric wire 7 disposed in the along-wire fitting portion 17 can be fitted, and the disposed shape of the electric wire 7 can be stably maintained. In addition, by disposing the along-wire fitting portion 17 along the electric wire 7, the along-wire fitting portion 17 can be used as a guide for disposing the electric wire 7, and the assemblability can be improved.

[0030] As a result, the cost of the wire harness assembly 1 can be reduced.

[0031] Reference will be made to Figures 3 to 7 describe the second embodiment.

[0032] In the wire harness assembly 101 according to the second embodiment, the assembly part 5 includes a main body part 103 and an extension part 105. The wire 7 is arranged in the main body part 103, the connector 9 is arranged in the extension part 105, and the extension part 105 is formed as a single part continuous with the main body part 103. The fitting part 15 has an avoidance fitting part 107 in the extension part 105, and the avoidance fitting part 107 is arranged at a position avoiding the connector 9 and the wire 7.

[0033] The extension part 105 has a dividing part 109 which can divide the extension part 105 to expose the connector 9.

[0034] Note that the same components as those in the first embodiment will be denoted by the same reference numerals, and since the first embodiment can be referred to, the description of their functions will be omitted. In addition, the actions and effects obtained from the same components are equivalent.

[0035] In this embodiment, as Figure 3 shown, the wire harness 3 includes three wires 7 and four connectors 9. The wire harness 3 is arranged inside the assembly part 5.

[0036] As Figures 3 to 7 shown, the assembly part 5 includes a main body part 103 and an extension part 105.

[0037] The main body part 103 is formed in a rectangular shape, for example. In the main body part 103, a plurality of (three in this embodiment) wires 7 are arranged between the base part 11 and the cover part 13 in a predetermined shape. In the main body part 103, a fitting part 17 along the line of the fitting part 15 is arranged, and the base part 11 and the cover part 13 are integrally joined to each other. In addition, by arranging the fitting part 17 along the line in the main body part 103, the arrangement shape of the wires 7 arranged in the main body part 103 can be stably maintained. In the main body part 103, the part where the fitting part 17 along the line is not arranged is the non-fitting area 19. Therefore, the amount of adhesive used can be reduced by the same amount as the non-fitting area 19 in the main body part 103 where no wires 7 are arranged.

[0038] The extension portion 105 is arranged relative to the main body portion 103 to correspond to each of the plurality of (four in this embodiment) connectors 9. The extension portion 105 extends outward from the outer edge of the main body portion 103 as a single component continuous with the main body portion 103. In the extension portion 105, the end portion of the electric wire 7 and the connector 9 are arranged between the base portion 11 and the cover portion 13. Therefore, the end portion of the electric wire 7 of the wire harness 3 and the connector 9 can be protected by the extension portion 105. By providing the extension portion 105 in the assembled component 5, direct interference between the connector 9 and the peripheral components can be prevented, for example, when the wire harness assembly 101 is packaged or assembled to the target component. For example, when the wire harness assembly 101 is packaged, if the extension portion 105 protrudes from the packaging box, the extension portion 105 can be folded back toward the main body portion 103. Even in such a state, the connector 9 is not exposed to the outside, and direct interference between the connector 9 and the peripheral components can be prevented. For example, when the wire harness assembly 101 is assembled to the target component, the extension portion 105 is removed, and the end portion of the electric wire 7 and the connector 9 are exposed from the assembled component 5. The fitting portion 15 arranged in the extension portion 105 includes an avoidance fitting portion 107.

[0039] The avoidance fitting portion 107 is arranged along the outer edge of the extension portion 105 to avoid the end portion of the electric wire 7 and the connector 9 between the base portion 11 and the cover portion 13 in the extension portion 105. The avoidance fitting portion 107 is formed on the base portion 11, but may also be formed on the cover portion 13. The avoidance fitting portion 107 fits the outer edge of the base portion 11 and the outer edge of the cover portion 13 to integrally attach the base portion 11 and the cover portion 13 in the extension portion 105. In the extension portion 105, the portion where the avoidance fitting portion 107 is not provided is the non-fitting area 19. Therefore, the amount of adhesive used can be reduced by the same amount as the non-fitting area 19 where the end portion of the electric wire 7 and the connector 9 are arranged in the extension portion 105. Since the end portion of the electric wire 7 and the connector 9 are not arranged in the avoidance fitting portion 107, the adhesive of the avoidance fitting portion 107 does not adhere to the end portion of the electric wire 7 and the connector 9. Therefore, in the state where the connector 9 is exposed from the assembled component 5, since the adhesive does not adhere to the connector 9, the connector 9 can be easily mated. The extension portion 105 provided with the avoidance fitting portion 107 has a dividing portion 109.

[0040] For example, the dividing portion 109 is formed by making a cut (notch) in the base portion 11 and the cover portion 13 located in the extension portion 105. In the extension portion 105, the dividing portion 109 is arranged at a position where the end portion of the electric wire 7 is exposed by a predetermined length when the extension portion 105 is removed. By dividing the extension portion 105 with the dividing portion 109, the extension portion 105 can be easily removed, and the connector 9 can be easily exposed from the assembled component 5. Therefore, it is not necessary to cut the extension portion 105 with a jig or the like to expose the connector 9 from the assembled component 5, and the assemblability can be improved. When the extension portion 105 does not protrude from the target component, the dividing portion 109 may be provided only in the cover portion 13. The dividing portion 109 provided in the cover portion 13 divides the portion to be removed of the cover portion 13 when the cover portion 13 is peeled off from the base portion 11 in the extension portion 105. Therefore, when exposing the connector 9, it is not necessary to press or cut the cover portion 13 at a predetermined position with a jig or the like, and the assemblability can be improved.

[0041] In the wire harness assembly 101 according to the present embodiment, the assembled component 5 includes a main body portion 103 and an extension portion 105. The electric wire 7 is arranged in the main body portion 103, and the connector 9 is arranged in the extension portion 105. The extension portion 105 is formed as a single component continuous with the main body portion 103. The fitting portion 15 has an avoidance fitting portion 107 in the extension portion 105, and the avoidance fitting portion 107 is arranged at a position to avoid the connector 9 and the electric wire 7.

[0042] By providing the extension portion 105 in the assembled component 5, the connector 9 can be protected. Therefore, it is possible to prevent, for example, direct interference between the connector 9 and peripheral components when the wire harness assembly 101 is packaged or assembled to the target component. Further, in the extension portion 105, since the fitting portion 15 has the avoidance fitting portion 107 arranged at a position to avoid the connector 9 and the electric wire 7, the portion where the avoidance fitting portion 107 is not arranged can be a non-fitting area 19. Therefore, the amount of adhesive used can be reduced as much as the non-fitting area 19 where the electric wire 7 and the connector 9 are arranged in the extension portion 105. Further, since the electric wire 7 and the connector 9 are not arranged in the avoidance fitting portion 107, the adhesive of the avoidance fitting portion 107 does not adhere to the electric wire 7 and the connector 9. Therefore, in a state where the connector 9 is exposed from the assembled component 5, since the adhesive does not adhere to the connector 9, the connector 9 can be easily mated.

[0043] The extension portion 105 has a dividing portion 109 that can divide the extension portion 105 to expose the connector 9.

[0044] By dividing the extension portion 105 with the dividing portion 109, the extension portion 105 can be easily removed, and the connector 9 can be easily exposed from the assembled component 5. Therefore, there is no need to cut the extension portion 105 with a jig or the like to expose the connector 9 from the assembled component 5, and the assemblability can be improved.

[0045] In the above embodiment, the number of the electric wires 7 in the wiring harness 3 is three or four, but the present invention is not limited thereto, and the number of the electric wires 7 may be two or less or may be five or more. In the above embodiment, one end sides of the plurality of electric wires 7 are gathered into one connector 9, but the present invention is not limited thereto, and the connector 9 may be provided on each end side of the plurality of electric wires 7.

[0046] Although specific embodiments have been described, these embodiments are disclosed only by way of example and are not intended to limit the scope of the present invention. In fact, the novel embodiments described herein can be implemented in various other forms; in addition, various omissions, substitutions, and changes in the forms of the embodiments described herein can be made without departing from the spirit of the present invention.
