Embodiments for Carrying Out the Invention

[0008] [Description of Embodiments of the Present Disclosure] First, the embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes [1] a plurality of shielded electric wires each having a core wire and an electromagnetic shielding member covering the outer periphery of the core wire, a connection portion where the plurality of core wires are connected to each other, an insulating member covering the outer periphery of the connection portion, an underlay member covering the outer periphery of the insulating member, a metal pipe covering the outer periphery of the underlay member, and a water stop plug interposed between the inner peripheral surface of the metal pipe at the end side in the length direction of the metal pipe and the outer peripheral surface of the shielded electric wire. The metal pipe has a shield connection portion that protrudes radially inward at an intermediate portion in the length direction of the metal pipe and is connected to the electromagnetic shielding member while sandwiching the electromagnetic shielding member with the underlay member.

[0009] According to this configuration, since the connection portion is covered by the metal pipe connected to the electromagnetic shielding member, radiation of electromagnetic waves from around the connection portion is suppressed. Further, since the connection portion and the electromagnetic shielding member are housed inside the metal pipe and the water stop plug, waterproofness is ensured. The metal pipe serves both as a member for ensuring the waterproofness of the connection portion and the electromagnetic shielding member and as a member for connecting the electromagnetic shielding members to each other. Therefore, the number of parts can be reduced.

[0010] [2] Preferably, the underlay member is configured to be disposed from the outside of the insulating member. According to this configuration, the underlay member is configured to be disposed from the outside of the insulating member. For example, since it is not necessary to pass the shielded electric wire through in advance like a pipe formed in a cylindrical shape, the assemblability is good.

[0011] [3] Preferably, the underlay member has flexibility and is formed in a C shape. According to this configuration, since it is possible to pass the insulating member inward from the opening of the C shape while bending the underlay member, the underlay member can be easily disposed from the outside of the insulating member.

[0012] [4] Preferably, the shield connection portion constitutes a positioning portion that restricts the movement of the water stop plug in the direction of the intermediate portion in the length direction of the metal pipe. According to the same configuration, the shield connection part also serves as a positioning part. Therefore, since there is no need for a separate member that restricts the movement of the water stop plug in the direction of the middle part in the length direction of the metal pipe, the number of parts can be reduced.

[0013] [5] Preferably, the water stop plug is a rubber plug. According to the same configuration, it can be made to closely adhere to the inner peripheral surface of the metal pipe and the outer peripheral surface of the shielded wire, and good waterproof performance can be ensured.

[0014] [6] Preferably, it is provided with a retainer that prevents the water stop plug from coming off the metal pipe. According to the same configuration, the retainer stably prevents the water stop plug from coming off the metal pipe.

[0015] [7] Preferably, the metal pipe has a retaining portion that protrudes radially inward on the end side of the water stop plug in the length direction of the metal pipe to prevent the water stop plug from coming off the metal pipe.

[0016] According to the same configuration, the retaining portion of the metal pipe stably prevents the water stop plug from coming off the metal pipe. And since there is no need for a retainer that prevents the water stop plug from coming off the metal pipe, the number of parts can be reduced.

[0017] [Details of the Embodiment of the Present Disclosure] A specific example of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be shown exaggeratedly or simplified. Also, the dimensional ratios of each part may be different in each drawing. "Parallel", "orthogonal", and "perfect circle" in this specification include not only the cases of strict parallelism, orthogonality, and perfect circle, but also the cases that are generally parallel, orthogonal, and perfect circle within the scope where the operational effects of the present embodiment are achieved. Note that the present invention is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0018] (Configuration of the wire harness 11) As shown in FIG. 1, the wire harness 11 includes one first shielded wire 12 as a shielded wire and two second shielded wires 13 and 14 as shielded wires. The first shielded wire 12 and the second shielded wires 13 and 14 have core wires 12a to 14a as core wires and inner insulating coatings 12b to 14b covering the outer circumferences of the core wires 12a to 14a. Further, the first shielded wire 12 and the second shielded wires 13 and 14 have electromagnetic shield members 12c to 14c covering the outer circumferences of the inner insulating coatings 12b to 14b and outer insulating coatings 12d to 14d covering the outer circumferences of the electromagnetic shield members 12c to 14c.

[0019] The electromagnetic shield members 12c to 14c suppress the radiation of electromagnetic waves from the core wires 12a to 14a. The electromagnetic shield members 12c to 14c in the present embodiment are, for example, braided wires in which conductive strands such as aluminum alloy are braided into a cylindrical shape.

[0020] At the ends of the first shielded wire 12 and the second shielded wires 13 and 14, the core wires 12a to 14a are provided so as to be exposed to the outside. Also, at the ends of the first shielded wire 12 and the second shielded wires 13 and 14, the electromagnetic shield members 12c to 14c are provided so as to be exposed to the outside.

[0021] At the ends of the first shielded wire 12 and the second shielded wires 13 and 14, first the outer insulating coatings 12d to 14d are peeled off, then the electromagnetic shield members 12c to 14c are folded back, and then the inner insulating coatings 12b to 14b are peeled off. As a result, the electromagnetic shield members 12c to 14c are exposed and the core wires 12a to 14a are exposed. Note that the electromagnetic shield members 12c to 14c exposed to the outside can be folded, bundled, or deformed, and are schematically illustrated in each figure.

[0022] The wire harness 11 also includes a crimp terminal 15 that forms a part of the connection portion and an insulating member 16. (Configuration of the crimp terminal 15) The crimp terminal 15 is made of, for example, a conductive metal plate material. The crimp terminal 15 is provided at a site where the respective core wires 12a to 14a exposed from the respective electromagnetic shield members 12c to 14c in the first shielded wire 12 and the second shielded wires 13 and 14 are aggregated. The crimp terminal 15 is crimped while surrounding the core wires 12a to 14a together to connect the core wires 12a to 14a. Note that the wire harness 11 is for electrically connecting, for example, a battery and two electrical devices. The first shielded wire 12 and the second shielded wires 13 and 14 are provided such that one first shielded wire 12 extends in one direction (left direction in FIG. 1) and two second shielded wires 13 and 14 extend in the other direction (right direction in FIG. 1) with the crimp terminal 15 as the center.

[0023] (Configuration of the insulating member 16) The outer periphery of the crimp terminal 15 is covered with an insulating member 16. The insulating member 16 is configured to be disposed from the outside of the crimp terminal 15. The insulating member 16 of the present embodiment is an insulating tape and is wound around the outside of the crimp terminal 15. The insulating member 16 is provided so as to cover all of the core wires 12a to 14a exposed from the inner insulating coatings 12b to 14b. Note that since the insulating member 16 is a flexible insulating tape, it does not necessarily become a perfect cylindrical state when wound around the outside of the crimp terminal 15, but is schematically illustrated as a cylindrical shape in FIG. 1 and the like.

[0024] The wire harness 11 further includes an underlay member 17, a metal pipe 18, water stoppers 19 and 20, and retainers 21 and 22. (Configuration of the underlay member 17) The underlay member 17 covers the outer periphery of the insulating member 16. The underlay member 17 is made of metal. The underlay member 17 is configured to be disposed from the outside of the insulating member 16.

[0025] Specifically, as shown in FIG. 2, the underlay member 17 is formed in a C shape. In other words, the underlay member 17 is formed in a shape obtained by cutting out a part in the circumferential direction from a cylindrical shape. The underlay member 17 has flexibility. The underlay member 17 can be bent so that the C-shaped opening 17a expands, and the crimp terminal 15 and the insulating member 16 can be passed through the C-shaped opening 17a from the inside. Therefore, the underlay member 17 can be disposed at a position covering the outer periphery of the insulating member 16 from the outside of the insulating member 16.

[0026] For example, as shown in FIG. 4 from the state shown in FIG. 3, the underlay member 17 is bent so that the C-shaped opening 17a expands, and the insulating member 16 is passed through the C-shaped opening 17a from the inside, thereby being disposed at a position covering the outer periphery of the insulating member 16. In the states shown in FIGS. 3 and 4, the electromagnetic shield members 12c to 14c exposed to the outside are folded back while being gathered and separated from each other.

[0027] As shown in FIGS. 1 and 5, the electromagnetic shield members 12c to 14c of the first shield wire 12 and the second shield wires 13 and 14 are arranged on the outer peripheral surface of the underlay member 17. The electromagnetic shield members 12c to 14c of the present embodiment are braided wires as described above, and a part of them is arranged on a part in the circumferential direction on the outer peripheral surface of the underlay member 17. That is, after the underlay member 17 is assembled to the insulating member 16 in a folded state as shown in FIGS. 3 and 4, the electromagnetic shield members 12c to 14c are deformed again so as to come into contact with the outer peripheral surface of the underlay member 17 as shown in FIG. 5.

[0028] (Configuration of the metal pipe 18) As shown in Fig. 1, the metal pipe 18 covers the outer circumference of the underlaying member 17. The metal pipe 18 is made of a conductive metal such as an aluminum alloy, for example. The length of the metal pipe 18 along the extending direction of the wire harness 11 is set to be longer than the length of the underlaying member 17. The metal pipe 18 has a shield connection portion 18a that protrudes radially inward at an intermediate portion in the length direction of the metal pipe 18 and sandwiches and connects to the electromagnetic shield members 12c to 14c with the underlaying member 17.

[0029] Specifically, as shown in Figs. 3 and 4, the metal pipe 18 has a cylindrical shape with a constant diameter in the material state before the shield connection portion 18a is formed. And when the crimp terminals 15 are crimped to the respective core wires 12a to 14a, the metal pipe 18 is arranged in a state where the first shielded wire 12 is passed through so as to surround the outer circumference of the first shielded wire 12 in the material state already. Then, as shown in Fig. 5, the metal pipe 18 is relatively moved in the extending direction of the wire harness 11 and arranged at a position covering the electromagnetic shield members 12c to 14c in a state where the electromagnetic shield members 12c to 14c are in contact with the outer peripheral surface of the underlaying member 17. And as shown in Fig. 1, the intermediate portion in the length direction of the metal pipe 18 is caulked radially inward to form the shield connection portion 18a, and the shield connection portion 18a sandwiches the electromagnetic shield members 12c to 14c with the underlaying member 17 during its deformation.

[0030] (Configuration of the water stop plugs 19, 20) The water stop plugs 19, 20 are rubber plugs made of rubber. The water stop plugs 19, 20 are provided inside both ends in the length direction of the metal pipe 18. Specifically, one water stop plug 19 is interposed between the inner peripheral surface at one end in the length direction of the metal pipe 18 and the outer peripheral surface of the first shielded wire 12, specifically, the outer peripheral surface of the outer insulating coating 12d. Also, the other water stop plug 20 is interposed between the inner peripheral surface at the other end in the length direction of the metal pipe 18 and the outer peripheral surfaces of the second shielded wires 13, 14, specifically, the outer peripheral surfaces of the outer insulating coatings 13d, 14d.

[0031] As shown in FIG. 3, when the crimp terminal 15 is crimped to each of the core wires 12a to 14a, one of the water stops 19 is arranged with the first shielded wire 12 passed therethrough so as to already surround the outer periphery of the first shielded wire 12. When the crimp terminal 15 is crimped to each of the core wires 12a to 14a, the other water stop 20 is arranged with the second shielded wires 13 and 14 passed therethrough so as to already surround the outer peripheries of the second shielded wires 13 and 14. Then, as shown in FIG. 1, the water stops 19 and 20 are relatively moved in the extending direction of the wire harness 11 with the shield connection portion 18a formed on the metal pipe 18 and are arranged inside both ends of the metal pipe 18. The movement of the water stops 19 and 20 in the direction of the middle portion in the length direction of the metal pipe 18 is restricted by the shield connection portion 18a. That is, in the present embodiment, the shield connection portion 18a constitutes a positioning portion that restricts the movement of the water stops 19 and 20 in the direction of the middle portion in the length direction of the metal pipe 18.

[0032] (Configuration of the retainers 21 and 22) The retainers 21 and 22 prevent the water stops 19 and 20 from coming off the metal pipe 18. Specifically, both ends of the metal pipe 18 of the present embodiment have a plurality of locking holes 18b penetrating in the radial direction in the circumferential direction. The retainers 21 and 22 have disk-shaped main body portions 21a and 22a that come into contact with the surfaces located in the direction of coming off the metal pipe 18 of the water stops 19 and 20, and locking claws 21b and 22b that extend from the outer edges of the main body portions 21a and 22a and fit into the locking holes 18b from the outside in the radial direction of the metal pipe 18.

[0033] As shown in FIG. 3, when the crimp terminal 15 is crimped to each of the core wires 12a to 14a, one of the retainers 21 is arranged with the first shielded wire 12 passed therethrough so as to already surround the outer periphery of the first shielded wire 12. When the crimp terminal 15 is crimped to each of the core wires 12a to 14a, the other retainer 22 is arranged with the second shielded wires 13 and 14 passed therethrough so as to already surround the outer peripheries of the second shielded wires 13 and 14. Then, as shown in FIG. 1, the retainers 21 and 22 are relatively moved in the extending direction of the wire harness 11 with the water stops 19 and 20 arranged at the ends of the metal pipe 18 and are locked to both ends of the metal pipe 18.

[0034] Next, the operation of the wire harness 11 configured as described above will be described. The first shielded wire 12 and the second shielded wires 13 and 14 have electromagnetic shield members 12c to 14c that cover the outer peripheries of the core wires 12a to 14a via the inner insulating coatings 12b to 14b. Therefore, the radiation of electromagnetic waves from the first shielded wire 12 and the second shielded wires 13 and 14 is suppressed. Further, the connection portion including the crimp terminals 15 to which the core wires 12a to 14a are connected is covered by the shield connection portion 18a of the metal pipe 18. Therefore, the radiation of electromagnetic waves from around the connection portion is suppressed.

[0035] Next, the effects of the above embodiment will be described below. (1) Since the crimp terminals 15 that form part of the connection portion are covered by the metal pipe 18 connected to the electromagnetic shield members 12c to 14c, the radiation of electromagnetic waves from around the crimp terminals 15 is suppressed. Further, since the crimp terminals 15 and the electromagnetic shield members 12c to 14c are housed inside the metal pipe 18 and the water stoppers 19 and 20, waterproofness is ensured. The metal pipe 18 serves both as a member for ensuring the waterproofness of the crimp terminals 15 and the electromagnetic shield members 12c to 14c and as a member for connecting the electromagnetic shield members 12c to 14c to each other. That is, in the prior art, a dedicated caulking member was used only for connecting the electromagnetic shield members 12c to 14c to each other, but in this embodiment, the caulking member is not required. Therefore, the number of parts can be reduced.

[0036] (2) The underlay member 17 is configured to be disposed from the outside of the insulating member 16, and for example, it is not necessary to pass the first shielded wire 12 through in advance like a pipe formed in a cylindrical shape, so the assemblability is good.

[0037] (3) The underlay member 17 has flexibility and is formed in a C shape. Therefore, since it is possible to pass the insulating member 16 through the C-shaped opening 17a from the inside while bending the underlay member 17, the underlay member 17 can be easily disposed from the outside of the insulating member 16.

[0038] (4) The shield connection part 18a also serves as a positioning part that restricts the movement of the water stop plugs 19 and 20 in the direction of the middle part in the longitudinal direction of the metal pipe 18. Therefore, since there is no need for a separate member to restrict the movement of the water stop plugs 19 and 20 in the direction of the middle part in the longitudinal direction of the metal pipe 18, the number of parts can be reduced.

[0039] (5) The water stop plugs 19 and 20 are rubber plugs. Therefore, they can be well adhered to the inner peripheral surface of the metal pipe 18 and the outer peripheral surfaces of the outer insulating coatings 12d to 14d, and good waterproof performance can be ensured.

[0040] (6) Retainers 21 and 22 are provided to prevent the water stop plugs 19 and 20 from coming off the metal pipe 18. Therefore, the water stop plugs 19 and 20 are stably prevented from coming off the metal pipe 18. This embodiment can be implemented with the following modifications. This embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0041] · In the above - described embodiment, the retainers 21 and 22 are configured to have locking claws 21b and 22b that fit into the locking holes 18b from the outside in the radial direction of the metal pipe 18, but it is not limited to this, and other configurations that can be locked to the metal pipe 18 may also be used.

[0042] For example, as shown in FIG. 6, the retainers 23 and 24 may be configured to have a main body part 23a and 24a and locking claws 23b and 24b that extend from the outer edge of the main body part 23a and 24a and fit into the locking holes 18b from the inside in the radial direction of the metal pipe 18.

[0043] · In the above - described embodiment, the wire harness 11 is configured to include the retainers 21 and 22, but if the water stop plugs 19 and 20 can be prevented from coming off the metal pipe 18, a configuration without the retainers 21 and 22 may also be used.

[0044] For example, as shown in FIG. 7, the metal pipe 18 may be configured to have a retaining portion 18c that protrudes radially inward on the end side of the water stoppers 19 and 20 in the longitudinal direction of the metal pipe 18 to prevent the water stoppers 19 and 20 from coming off the metal pipe 18. Note that the retaining portion 18c is a caulked portion formed by caulking or a swaged portion formed by swaging in a state where the water stoppers 19 and 20 are disposed inside the metal pipe 18.

[0045] By doing so, retainers 21 and 22 for preventing the water stoppers 19 and 20 from coming off the metal pipe 18 become unnecessary, so that the number of parts can be reduced. · In the above embodiment, the underlay member 17 is formed in a C shape and is configured to be disposed from the outside of the insulating member 16, but is not limited thereto. For example, it may be a pipe formed in a cylindrical shape.

[0046] · In the above embodiment, the shield connection portion 18a also serves as a positioning portion that restricts the movement of the water stoppers 19 and 20 in the direction of the middle portion in the longitudinal direction of the metal pipe 18, but is not limited thereto. For example, the positioning portion that restricts the movement of the water stoppers 19 and 20 may be formed on the metal pipe 18 separately from the shield connection portion 18a, or may be provided as a separate member.

[0047] · In the above embodiment, the water stoppers 19 and 20 are rubber stoppers made of rubber, but are not limited thereto, and may be water stoppers made of other materials. For example, as a resin-made water stopper, one that ensures waterproofness with an adhesive may be used.

[0048] · In the above embodiment, the insulating member 16 is an insulating tape wound around the outside of the crimp terminal 15, but is not limited thereto, and may be changed to other insulating parts. For example, the insulating member 16 in the above embodiment may be changed to a heat-shrinkable tube formed in a cylindrical shape. Note that since the heat-shrinkable tube formed in a cylindrical shape is not configured to be disposed from the outside of the crimp terminal 15, for example, it is necessary to pass the first shielded wire 12 through the heat-shrinkable tube in advance.

[0049] · In the above embodiment, the wire harness 11 is provided with one first shielded wire 12 and two second shielded wires 13 and 14, but it may be configured to include four or more shielded wires.

[0050] · In the above embodiment, the connection portion to which the core wires 12a to 14a are connected has a crimp terminal 15, but the connection portion is not limited thereto. For example, the core wires 12a to 14a may be connected by welding. That is, the connection portion may have a welded portion instead of the crimp terminal 15.
