Modes for Carrying Out the Invention
[0009] Hereinafter, the wire harness assembly according to this embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from the actual ratios.
[0010] (First Embodiment) The first embodiment will be described with reference to FIGS. 1 and 2.
[0011] As shown in FIG. 1, the wire harness assembly 1 according to this embodiment is applied to a wire harness 3 that electrically connects between electrical components (not shown), such as between a power source mounted on a vehicle and a device, or between devices. The wire harness 3 is arranged in a predetermined shape inside an assembly member 5 that is integrally assembled. The wire harness assembly 1 is assembled to a target member (not shown), such as a door trim of a vehicle.
[0012] As shown in FIGS. 1 and 2, the wire harness assembly 1 includes a wire harness 3 and an assembly member 5.
[0013] As shown in FIGS. 1 and 2, the wire harness 3 includes electric wires 7 and connectors 9.
[0014] The electric wire 7 is, for example, a covered electric wire in which the outer periphery of a core wire made of a conductive material is covered with an insulating coating, and a plurality (here, four) are used. Note that the electric wire 7 may be a flat cable in which a plurality of core wires are arranged in parallel and the outer periphery is covered with an insulating coating. The terminal portions on both sides of the plurality of electric wires 7 are respectively exposed from the assembly member 5 and arranged. The terminal portions on one end side of the plurality of electric wires 7 are gathered and arranged at one location, and the terminal portions on the other end side are arranged so as to branch respectively.
[0015] The connector 9 includes a housing (not shown) made of an insulating material such as synthetic resin and terminals (not shown) made of a conductive material. The housing is capable of fitting with a mating housing (not shown) of a mating connector (not shown) electrically connected to an electrical component mounted on a vehicle, for example. The terminals are electrically connected to the terminal portions of the electric wires 7 and are housed in the housing. When the housing and the mating housing are fitted together, the terminals are electrically connected to mating terminals (not shown) housed in the mating housing. A plurality (here, five) of connectors 9 are used corresponding to the terminal portions of the plurality of electric wires 7 exposed from the assembling member 5.
[0016] As shown in FIGS. 1 and 2, the assembling member 5 includes a base material 11 and a cover material 13.
[0017] The base material 11 is made of, for example, a foam such as urethane, a non-woven fabric such as polypropylene fiber, polyethylene terephthalate fiber, or polyester-based fiber, and has sound insulation and heat insulation properties. The base material 11 is formed in a sheet shape with a size set so as to be disposed within the range of the target member, and is assembled to the target member by fixing means (not shown) such as press-fitting. A plurality (here, four) of electric wires 7 of the wire harness 3 are arranged on one side surface of the base material 11 in a predetermined shape. The terminal portions of the plurality of electric wires 7 arranged on the base material 11 are exposed from the outer edge of the base material 11 with each electric wire 7 having a predetermined length, and the connector 9 is disposed outside the base material 11.
[0018] The cover material 13 is made of, for example, films such as vinyl chloride and polyethylene, and foams such as independent foams and continuous foams of polyethylene, polypropylene, polystyrene, and elastomers, and has sound insulation and heat insulation properties. The cover material 13 is formed in a sheet shape with a size set to be equivalent to that of the base material 11 so as to be disposed within the range of the target member, and a thickness set to be thinner than that of the base material 11. The cover material 13 is attached to one surface side of the base material 11 so as to sandwich the base material 11 and the plurality of electric wires 7 by an adhesive portion 15 made of an adhesive provided on the opposing surface to the base material 11. In a state where the cover material 13 is attached to the base material 11, a plurality of electric wires 7 arranged in a predetermined shape are held inside the base material 11 and the cover material 13. Therefore, the electric wires 7 of the wire harness 3 can be protected by the assembling member 5, and the arrangement shape of the electric wires 7 can be maintained.
[0019] The connector 9 exposed from the assembling member 5 is fitted to a mating connector in a state where the wire harness assembly 1 is assembled to the target member. At this time, since the electric wire 7 has a predetermined length and is exposed from the outer edge of the assembling member 5, the connector 9 can be freely moved, facilitating the fitting of the connector 9 and the mating connector. By fitting the connector 9 and the mating connector, the electrical components are electrically connected.
[0020] Here, in a conventional wire harness assembly, the adhesive portion 15 for attaching the base material 11 and the cover material 13 was provided on the entire surface of the assembling member 5. For this reason, the amount of adhesive used for the adhesive portion 15 was large, resulting in a high cost.
[0021] Therefore, the adhesive portion 15 includes a linear adhesive portion 17. And a non-adhesive region 19 where the adhesive portion 15 is not disposed is provided between the base material 11 and the cover material 13.
[0022] The along-wire bonding part 17 is arranged along the electric wire 7 disposed inside the assembling member 5 between the base material 11 and the cover material 13 of the assembling member 5. The along-wire bonding part 17 is formed on the base material 11, for example, by disposing a masking sheet (not shown) having the same shape as the base material 11 and having through holes formed in the portion of the along-wire bonding part 17 on one side of the base material 11 and spraying an adhesive. Note that the along-wire bonding part 17 may be formed on the cover material 13. The along-wire bonding part 17 bonds the portions of the base material 11 and the cover material 13 where the electric wire 7 is disposed, and attaches the base material 11 and the cover material 13 integrally. By providing the along-wire bonding part 17 at the portion of the assembling member 5 where the electric wire 7 is disposed, the base material 11 and the cover material 13 can be made integral, and the portion of the assembling member 5 where the electric wire 7 is not disposed can be made a non-bonding region 19 where the bonding part 15 is not disposed. For this reason, the amount of the adhesive used for the non-bonding region 19 where the electric wire 7 of the assembling member 5 is not disposed can be reduced. In addition, by arranging the along-wire bonding part 17 along the electric wire 7, the electric wire 7 disposed on the along-wire bonding part 17 can be bonded, and the arrangement shape of the electric wire 7 can be stably held. Furthermore, by arranging the along-wire bonding part 17 along the electric wire 7, the along-wire bonding part 17 can be used as a guide for arranging the electric wire 7, and the assemblability can be improved.
[0023] In such a wire harness assembly 1, there is provided a wire harness 3 having an electric wire 7 and a connector 9 electrically connected to the terminal part of the electric wire 7, and an assembling member 5 in which the wire harness 3 is disposed inside. The assembling member 5 has a base material 11 and a cover material 13 attached to the base material 11 via a bonding part 15. Further, the bonding part 15 has an along-wire bonding part 17 arranged along the electric wire 7. And a non-bonding region 19 where the bonding part 15 is not disposed is provided between the base material 11 and the cover material 13.
[0024] By having the connecting portion 15 with the along-line adhesive portion 17, the base material 11 and the cover material 13 can be integrated, and the non-adhesive region 19 where the adhesive portion 15 is not arranged can be set as the portion where the electric wire 7 of the assembling member 5 is not arranged. Therefore, the amount of the adhesive used for the non-adhesive region 19 where the electric wire 7 of the assembling member 5 is not arranged can be reduced. In addition, by arranging the along-line adhesive portion 17 along the electric wire 7, the electric wire 7 arranged at the along-line adhesive portion 17 can be adhered, and the arranged shape of the electric wire 7 can be stably held. Furthermore, by arranging the along-line adhesive portion 17 along the electric wire 7, the along-line adhesive portion 17 can be used as a guide for arranging the electric wire 7, and the assemblability can be improved.
[0025] Therefore, in such a wire harness assembly 1, the cost can be reduced.
[0026] (Second Embodiment) The second embodiment will be described with reference to FIGS. 3 to 7.
[0027] The wire harness assembly 101 according to the present embodiment includes an assembling member 5 having a main body portion 103 in which the electric wire 7 is arranged inside, and an extending portion 105 formed of a member continuous with the main body portion 103 and having a connector 9 arranged inside. And the adhesive portion 15 has an avoidance adhesive portion 107 arranged at a position avoiding the connector 9 and the electric wire 7 in the extending portion 105.
[0028] In addition, the extending portion 105 is provided with a dividing portion 109 capable of dividing the extending portion 105 so as to expose the connector 9.
[0029] Note that the same symbols are used for the same configurations as those in the first embodiment, and the functional description is omitted with reference to the first embodiment. However, since the configurations are the same, the obtained operations and effects are equivalent.
[0030] In the present embodiment, as shown in FIG. 3, the wire harness 3 is composed of three electric wires 7 and four connectors 9. This wire harness 3 is arranged inside the assembling member 5.
[0031] As shown in FIGS. 3 to 7, the assembling member 5 includes a main body portion 103 and an extending portion 105.
[0032] The main body portion 103 is formed, for example, in a rectangular shape. Between the base material 11 and the cover material 13 in the main body portion 103, a plurality (here, three) of electric wires 7 are arranged in a predetermined shape. In the main body portion 103, a linear adhesive portion 17 of the adhesive portion 15 is arranged, and the base material 11 and the cover material 13 are integrally attached. In addition, by arranging the linear adhesive portion 17 along the main body portion 103, the arranged shape of the electric wires 7 arranged in the main body portion 103 can be stably held. In the main body portion 103, a portion where the linear adhesive portion 17 is not arranged becomes a non-adhesive region 19. Therefore, the amount of adhesive used in the non-adhesive region 19 where the electric wires 7 of the main body portion 103 are not arranged can be reduced.
[0033] The extending portion 105 is arranged corresponding to each of a plurality (here, four) of connectors 9 with respect to the main body portion 103. The extending portion 105 is a member continuous with the main body portion 103 and extends outward from the outer edge of the main body portion 103. Between the base material 11 and the cover material 13 in the extending portion 105, the terminal portion of the electric wire 7 and the connector 9 are arranged. Therefore, the extending portion 105 can protect the terminal portion of the electric wire 7 and the connector 9 of the wire harness 3. By providing the extending portion 105 on the assembling member 5, for example, direct interference between the connector 9 and peripheral members can be prevented when the wire harness assembly 101 is packaged or assembled to a target member. Incidentally, for example, when the wire harness assembly 101 is packaged, if the extending portion 105 protrudes from the packaging box, the extending portion 105 may 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 peripheral members can be prevented. The extending portion 105 is removed, for example, when the wire harness assembly 101 is assembled to a target member, and the terminal portion of the electric wire 7 and the connector 9 are exposed from the assembling member 5. The adhesive portion 15 arranged in the extending portion 105 includes an avoidance adhesive portion 107.
[0034] The avoiding adhesion part 107 is arranged along the outer edge of the extending part 105 so as to avoid the terminal part of the electric wire 7 and the connector 9 between the base material 11 and the cover material 13 of the extending part 105. Note that the avoiding adhesion part 107 is formed on the base material 11, but it may also be formed on the cover material 13. The avoiding adhesion part 107 adheres the outer edges of the base material 11 and the cover material 13 in the extending part 105, and attaches the base material 11 and the cover material 13 integrally. In the extending part 105, the portion where the avoiding adhesion part 107 is not arranged becomes the non-adhesion area 19. Therefore, the amount of adhesive used in the non-adhesion area 19 where the terminal part of the electric wire 7 and the connector 9 of the extending part 105 are arranged can be reduced. Since the terminal part of the electric wire 7 and the connector 9 are not arranged in the avoiding adhesion part 107, the adhesive of the avoiding adhesion part 107 does not adhere to the terminal part of the electric wire 7 and the connector 9. Therefore, in the state where the connector 9 is exposed from the assembling member 5, since no adhesive adheres to the connector 9, the fitting of the connector 9 can be easily performed. A dividing part 109 is provided in the extending part 105 where the avoiding adhesion part 107 is arranged.
[0035] The dividing part 109 is formed, for example, by making cuts (notches) in the base material 11 and the cover material 13 located in the extending part 105. The dividing part 109 is arranged in the extending part 105 at a position where the terminal part of the electric wire 7 is exposed with a predetermined length when the extending part 105 is removed. By dividing the extending part 105 at the dividing part 109, the extending part 105 can be easily removed, and the connector 9 can be easily exposed from the assembling member 5. Therefore, when the connector 9 is exposed from the assembling member 5, it is not necessary to cut the extending part 105 with a jig or the like, and the assembling property can be improved. Note that when the extending part 105 does not protrude from the target member, the dividing part 109 may be provided only on the cover material 13. The dividing part 109 provided on the cover material 13 divides the portion of the cover material 13 to be removed when the cover material 13 is peeled off from the base material 11 in the extending part 105. Therefore, when the connector 9 is exposed, it is not necessary to hold or cut the cover material 13 at a predetermined position with a jig or the like, and the assembling property can be improved.
[0036] In such a wire harness assembly 101, the assembling member 5 has a main body portion 103 in which the electric wire 7 is disposed inside, and an extending portion 105 formed of a member continuous with the main body portion 103 and in which the connector 9 is disposed inside. And the adhesion portion 15 has an avoidance adhesion portion 107 disposed at a position avoiding the connector 9 and the electric wire 7 in the extending portion 105.
[0037] Since the assembling member 5 has the extending portion 105, the connector 9 can be protected. For this reason, for example, direct interference between the connector 9 and peripheral members can be prevented when the wire harness assembly 101 is packaged or assembled to a target member. Further, in the extending portion 105, since the adhesion portion 15 has the avoidance adhesion portion 107 disposed at a position avoiding the connector 9 and the electric wire 7, a non-adhesion region 19 can be formed in a portion where the avoidance adhesion portion 107 is not disposed. For this reason, the amount of adhesive used in the non-adhesion region 19 where the electric wire 7 and the connector 9 of the extending portion 105 are disposed can be reduced. Furthermore, since the electric wire 7 and the connector 9 are not disposed in the avoidance adhesion portion 107, the adhesive of the avoidance adhesion portion 107 does not adhere to the electric wire 7 and the connector 9. For this reason, in a state where the connector 9 is exposed from the assembling member 5, since no adhesive adheres to the connector 9, the connector 9 can be easily fitted.
[0038] Further, the extending portion 105 is provided with a dividing portion 109 capable of dividing the extending portion 105 so as to expose the connector 9.
[0039] By dividing the extending portion 105 at the dividing portion 109, the extending portion 105 can be easily removed, and the connector 9 can be easily exposed from the assembling member 5. For this reason, when the connector 9 is exposed from the assembling member 5, it is not necessary to cut the extending portion 105 with a jig or the like, and the assemblability can be improved.
[0040] As described above, although the present embodiment has been described, the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment.
[0041] For example, the wires of the wire harness are three or four, but not limited thereto, and the number of wires may be two or less, or five or more. In addition, one end side of a plurality of wires is aggregated into one connector, but not limited thereto, and a connector may be provided for each of one end sides of the plurality of wires.
