[0009] [Description of Embodiments of the Present Invention] First, embodiments of the present invention will be illustrated.

[0010] The wiring module of the present invention is as follows.

[0011] (1) A wiring module including: a shielded wire having a core wire, a core wire covering portion covering the core wire, a shield portion covering the core wire covering portion, and a shield portion covering portion covering the shield portion; an unshielded wire having an unshielded core wire and an unshielded core wire covering portion covering the unshielded core wire, wherein an end of the unshielded core wire is connected to an end of the core wire; an insulating member covering a connection portion of the unshielded core wire and the core wire; a cylindrical shield member including a cylindrical shield portion and having a rigidity sufficient to hold a path of the unshielded wire, covering the unshielded wire in a state where an end of the shield portion is connected to an end of the cylindrical shield portion; and a water stop member covering a connection portion of the shield portion and the cylindrical shield member in a state where one end is fixed to an end of the shield portion covering portion in a water stop state and the other end is fixed to an end of the cylindrical shield member in a water stop state.

[0012] According to this wiring module, when connecting the unshielded wire and the shielded wire, the cylindrical shield member can impart shielding properties and a path holding function to the conductive path of the unshielded wire. In addition, in a state where one end of the water stop member is fixed to an end of the shield portion covering portion in a water stop state and the other end of the water stop member is fixed to an end of the cylindrical shield member in a water stop state, the water stop member covers the connection portion of the shield portion and the cylindrical shield member, so that water tightness can be imparted to the connection portion of the two wires.

[0013] (2) In the wiring module of (1), the cylindrical shield member may include a metal tube as the cylindrical shield portion.

[0014] Thus, when the cylindrical shielding member includes a metal tube, it is easy to endow the conductive path of the unshielded wire with a path holding function and shielding property through a single component.

[0015] (3) In the wiring module of (1), it is also possible that the cylindrical shielding member includes a cylindrical braid as the cylindrical shielding portion and a resin tube covering the cylindrical braid.

[0016] Thus, shielding property can be endowed by the cylindrical braid, and a path holding function can be endowed by the resin tube.

[0017] (4) In the wiring module according to any one of (1) to (3), it is also possible that the core wire is made of copper or a copper alloy, and the unshielded core wire is made of aluminum or an aluminum alloy.

[0018] Thus, by setting the portion of the wiring path protected by the cylindrical shielding member to an unshielded core wire made of aluminum or an aluminum alloy, cost reduction and weight reduction can be achieved. Regarding the shielded wire, by using a core wire made of copper or a copper alloy, it is easy to bend and the wiring workability is excellent.

[0019] (5) In the wiring module according to any one of (1) to (4), it is also possible that the unshielded core wire is a solid conductor filled inside.

[0020] Thus, miniaturization of the unshielded wire can be achieved, and it is easy for the unshielded wire itself to have a path holding function.

[0021] (6) In the wiring module according to any one of (1) to (5), it is also possible that a metal band is further provided, and the metal band fastens the end portion of the shielding portion and the end portion of the cylindrical shielding portion in a state where the end portion of the metal band overlaps with the outer periphery or the inner periphery of the end portion of the cylindrical shielding portion.

[0022] Thus, the shielding portion and the cylindrical shielding portion can be firmly fixed in an electrically connected state.

[0023] (7) In the wiring module according to any one of (1) to (5), it is also possible that the cylindrical shielding member has a bent portion bent at an intermediate portion in the extending direction, and holds the unshielded wire along the bent path.

[0024] Thus, the unshielded wire can be held along the bent path by the cylindrical shielding member.

[0025] (8) In the wiring module according to any one of (1) to (7), it is also possible that two sets of the shielded wire, the insulating member, and the water stop member are provided, the two shielded wires are connected to both ends of the unshielded wire, and the two insulating members and the two water stop members are respectively provided on both ends of the unshielded wire.

[0026] Thus, even when an unshielded wire is used between portions between two shielded wires, shielding properties and a path maintaining function can be imparted, and water stoppage properties can be imparted to the connection portion of the wires.

[0027] [Details of Embodiment of the Present Invention] Hereinafter, a specific example of the wiring module of the present invention will be described with reference to the drawings. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0028] [Embodiment 1] Hereinafter, the wiring module of Embodiment 1 will be described. Figure 1 is a front view showing the wiring module 10. Figure 2 is Figure 1 a cross-sectional view taken along line II-II of

[0029] The wiring module 10 includes a shielded wire 20, an unshielded wire 30, an insulating member 40, a cylindrical shielding member 50, and a water stoppage member 60.

[0030] The shielded wire 20 includes a core wire 22, a core wire covering portion 24, a shielding portion 26, and a shielding portion covering portion 28.

[0031] The core wire 22 is a metal linear member formed of copper, a copper alloy, aluminum, an aluminum alloy, or the like. The core wire 22 may be a single-core wire or a stranded wire. In the present embodiment, it is assumed that the core wire 22 is made of copper or a copper alloy. Therefore, the core wire 22 is more easily bent than a core wire formed of aluminum or an aluminum alloy. In addition, it is assumed that the core wire 22 is a stranded wire. Therefore, the core wire 22 is more easily bent than a core wire formed of a single-core wire. The core wire 22 can be used as a transmission medium for transmitting electric power or signals.

[0032] The core wire covering portion 24 is an insulating member that covers the core wire 22. The core wire covering portion 24 is formed, for example, by extrusion-coating a molten resin around the core wire 22.

[0033] The shielding portion 26 is a member that covers the core wire covering portion 24 and is formed of a material capable of electromagnetic shielding. For example, the shielding portion 26 is formed of iron, copper, or aluminum. The shielding portion 26 has a cylindrical shape to cover the entire outer circumference of the core wire covering portion 24. For example, the shielding portion 26 is a braided member formed by braiding metal wires into a cylindrical shape. The shielding portion 26 may also be a shielding portion formed by winding a metal tape such as an aluminum tape around the core wire covering portion 24.

[0034] The shielding portion covering portion 28 is an insulating member that covers the shielding portion 26. The shielding portion covering portion 28 is formed, for example, by extrusion-coating a molten resin around the shielding portion 26 of the core wire 22.

[0035] The above-mentioned core wire covering portion 24, shielding portion 26 or shielding portion covering portion 28 can be either single-layer or have a multi-layer structure. The shielded electric wire 20 can include a plurality of electric wires having a core wire and a core wire covering portion inside the shielding portion 26.

[0036] The non-shielded electric wire 30 has a non-shielded core wire 32 and a non-shielded core wire covering portion 34.

[0037] The non-shielded core wire 32 is a metallic linear member formed of copper, copper alloy, aluminum, aluminum alloy, etc. The non-shielded core wire 32 can be either a single-core wire or a stranded wire. In the present embodiment, it is assumed that the non-shielded core wire 32 is made of aluminum or aluminum alloy. Therefore, the non-shielded core wire 32 is less likely to bend compared to a core wire formed of copper or copper alloy and has excellent path-holding function. In addition, it is assumed that the non-shielded core wire 32 is a single-core wire. Therefore, the non-shielded core wire 32 is less likely to bend compared to a core wire formed of a stranded wire and has excellent path-holding function. The non-shielded core wire 32 can be used as a transmission medium for transmitting electric power or signals. The non-shielded core wire 32 can be either a bus bar formed by processing a metal into a strip shape or a rod-shaped member obtained by extruding and forming a metal into a round shape.

[0038] In the case where the non-shielded core wire 32 is a single-core wire, a bus bar or a rod-shaped member which is an extrusion-molded product of a metal, the non-shielded core wire 32 is a solid conductive body filled inside.

[0039] The non-shielded core wire covering portion 34 is an insulating member covering the non-shielded core wire 32. The non-shielded core wire covering portion 34 is formed, for example, by extruding and covering molten resin around the non-shielded core wire 32. The non-shielded core wire covering portion 34 can also be a heat-shrinkable tube that heat-shrinks in a manner of covering the non-shielded core wire 32, a resin mold molding obtained by molding the non-shielded core wire 32 as an insert, or a resin tube.

[0040] At both end portions of the non-shielded core wire covering portion 34, both end portions of the non-shielded core wire 32 are exposed. The end portion of the non-shielded core wire 32 is connected to the end portion of the core wire 22. For example, the end portion of the non-shielded core wire 32 is joined to the end portion of the core wire 22. The joining is performed, for example, by welding such as ultrasonic joining, resistance welding, or brazing such as soldering.

[0041] The insulating member 40 covers the connection portion of the non-shielded core wire 32 and the core wire 22. The insulating member 40 is located on the inner peripheral side of the shielding portion 26 or the cylindrical shielding portion and has the function of insulating the connection portion of the non-shielded core wire 32 and the core wire 22 from the shielding portion 26 or the cylindrical shielding portion. One end portion of the insulating member 40 can also be fixed to the end portion of the core wire covering portion 24 in a water-stopping state, and the other end portion of the insulating member 40 can also be fixed to the end portion of the non-shielded core wire covering portion 34 in a water-stopping state. Thereby, the connection portion of the non-shielded core wire 32 and the core wire 22 can be made to stop water more reliably.

[0042] In the present embodiment, the insulating member 40 is, for example, a heat-shrinkable tube that heat-shrinks in a state of covering the connection portion between the non-shielded core wire 32 and the core wire 22. The end portions of the heat-shrinkable tube cover the exposed portions of the core wire 22 and the non-shielded core wire 32, and are interposed between the core wire 22 and the non-shielded core wire 32 and the shielding portion 26. One end portion of the heat-shrinkable tube fastens the end portion of the core wire covering portion 24, and the other end portion of the heat-shrinkable tube fastens the end portion of the non-shielded core wire covering portion 34. A hot melt adhesive may be provided inside the heat-shrinkable tube, and the hot melt adhesive seals between the heat-shrinkable tube and the covering portions 24 and 34.

[0043] The insulating member 40 is not limited to the above example, and may be an adhesive tape or a resin sheet wound around the connection portion between the non-shielded core wire 32 and the core wire 22, or may be a resin portion formed by molding the connection portion as an insert portion. The insulating member 40 may also be a cylindrical member formed of an elastic material such as rubber.

[0044] The cylindrical shielding member 50 includes a cylindrical shielding portion and has a rigidity sufficient to hold the path of the non-shielded electric wire 30.

[0045] In the present embodiment, the cylindrical shielding member 50 is a metal tube, and the entire cylindrical shielding member 50 is a cylindrical shielding portion. The metal tube is, for example, a tube made of aluminum or aluminum alloy, iron, or stainless steel. In the present embodiment, it is assumed that the metal tube is a tube made of aluminum or aluminum alloy. An insulating layer may be provided on the outer periphery or the inner periphery of the metal tube.

[0046] Since the cylindrical shielding member 50 is formed of a metal tube, it has a rigidity sufficient to hold the path of the non-shielded electric wire 30. The so-called rigidity sufficient to hold the path of the non-shielded electric wire 30 is, for example, the rigidity such that when the two ends of the cylindrical shielding member 50 are supported at constant positions, the rigidity of the cylindrical shielding member 50 and the rigidity of the non-shielded electric wire 30 are combined to hold the initial path bent due to its own weight.

[0047] The cylindrical shielding member 50 covers the non-shielded electric wire 30 in a state where the end portion of the shielding portion 26 is connected to the end portion of the cylindrical shielding member 50 serving as the cylindrical shielding portion.

[0048] The connection between the end of the cylindrical shielding member 50 and the end of the shielding portion 26 is performed as follows, for example. The end of the shielding portion 26 extends beyond the end of the shielding portion covering portion 28 and covers the outer periphery of the end of the cylindrical shielding member 50 in an overlapping manner. And, a metal band 58 is fastened at the overlapping portion between the end of the cylindrical shielding member 50 and the end of the shielding portion 26. The metal band 58 is formed of, for example, copper, aluminum, iron, stainless steel, or various alloys. The metal band 58 is, for example, an annular member that can be plastically deformed, or a member that is plastically deformed in such a manner as to fasten the shielding portion 26 to the outer peripheral side of the cylindrical shielding member 50. The metal band 58 can also be, for example, a member that presses the shielding portion 26 against the outer periphery of the cylindrical shielding member 50 by the fastening action of a screw. The connection between the end of the cylindrical shielding member 50 and the end of the shielding portion 26 is not limited to the above structure and can also be performed by welding, tape, etc.

[0049] The water stop member 60 covers the connection portion between the shielding portion 26 and the cylindrical shielding member 50 in a state where one end is fixed to the end of the shielding portion covering portion 28 in a water-stop state and the other end is fixed to the end of the cylindrical shielding member 50 in a water-stop state. The other end of the water stop member 60 is located at a position closer to the center of the cylindrical shielding member 50 than the metal band 58.

[0050] The water stop member 60 can also be, for example, a cylindrical cover formed of an elastic material such as rubber. The water stop member 60 can also be a molded product of an elastic material by die molding.

[0051] Both end portions of the water stop member 60 can be formed into a cylindrical shape having an inner diameter capable of fastening the end portion of the shielding portion covering portion 28 and the end portion of the cylindrical shielding member 50. Thus, the inner peripheral surfaces of both end portions of the water stop member 60 are in close contact with the outer peripheral surfaces of the end portion of the shielding portion covering portion 28 and the end portion of the cylindrical shielding member 50, and water is difficult to infiltrate between them.

[0052] Both end portions of the water stop member 60 can also be fastened by a bundling member 68. The bundling member 68 is, for example, a member formed of resin and called a bundling band (band or tie). By the bundling member 68, both end portions of the water stop member 60 are strongly pressed by the end portion of the shielding portion covering portion 28 and the end portion of the cylindrical shielding member 50, and water is even more difficult to infiltrate between them. The bundling member 68 can be an adhesive tape or the like, or can also be a metal band.

[0053] The middle part in the extending direction of the water-stop member 60 may also be shaped to have an inner diameter corresponding to the outer diameter of the connection part of the shielded wire 20 and the unshielded wire 30. For example, the outer diameter of the part where the insulating member 40 and the metal strip 58 are provided in the connection part of the shielded wire 20 and the unshielded wire 30 is larger than the outer diameter of other parts. Therefore, the inner diameter of the middle part in the extending direction of the water-stop member 60 may also be formed larger than the inner diameter of the two end regions, and further, the inner diameter of the part for accommodating the metal strip 58 may also be formed larger than the inner diameter of other parts. The water-stop member 60 may also be a heat-shrinkable tube or the like.

[0054] In addition, in the present embodiment, the wiring module 10 includes two shielded wires 20, and an unshielded wire 30 is disposed between the two shielded wires 20. It can also be understood that a part in the middle of the shielded wire 20 is replaced by the unshielded wire 30.

[0055] The wiring module 10 includes two sets of insulating members 40 and water-stop members 60 in order to connect the shielded wires 20 to both ends of the unshielded wire 30 respectively.

[0056] The connection structures of the above-mentioned core wire 22 and the unshielded core wire 32, the connection structure of the shielding part 26 and the cylindrical shielding member 50, and the connection structure including the insulating member 40 and the water-stop member 60 are respectively applied to both ends of the unshielded wire 30, and the shielded wires 20 are connected.

[0057] According to the wiring module 10 configured as above, when connecting the unshielded wire 30 to the shielded wire 20, the cylindrical shielding member 50 can endow the conduction path of the unshielded wire 30 with shielding property and path-holding function. In addition, with one end of the water-stop member 60 fixed to the end of the shielding part covering part 28 in a water-stop state, and the other end of the water-stop member 60 fixed to the end of the cylindrical shielding member 50 in a water-stop state, the water-stop member 60 covers the connection part of the shielding part 26 and the cylindrical shielding member 50, so the connection part of the two wires 20 and 30 can be given water-tightness. Therefore, when connecting the unshielded wire 30 to the shielded wire 20, the conduction path of the unshielded wire 30 can be given shielding property and path-holding function, and the connection part of the wires 20 and 30 can be given water-tightness.

[0058] In addition, the requirement to connect the unshielded wire 30 to the shielded wire 20 may arise, for example, in the following situations. That is, the shielded wire 20 is used in power transmission applications. As the shielded wire 20 for power use, for example, a shielded wire having a copper core wire as the core wire 22 is selected. However, the copper core wire used for power transmission is thicker and the amount of copper used is larger, so the shielded wire 20 is also likely to become expensive. Therefore, there is a requirement to replace a part of the shielded wire 20 with a cheaper unshielded wire 30. As the cheaper unshielded wire 30, for example, it is assumed to have a core wire made of aluminum or aluminum alloy.

[0059] However, if only a part of the shielded wire 20 is replaced with the unshielded wire 30, the shielding function is lacking. In addition, water may intrude into the connection part.

[0060] In such a case, according to the present embodiment, the tubular shielding member 50 can impart shielding property to the conduction path of the unshielded wire 30 and can impart water stoppage property to the connection part.

[0061] In addition, generally, copper can be used in places where the feature of being more easily bendable than aluminum or aluminum alloy is effectively utilized. As a place where the shielded wire 20 having a copper core wire is replaced with the unshielded wire 30 having an aluminum core wire or an aluminum alloy core wire, a place where bending operation is not required during laying, that is, a place where the path is constant is suitable. The path holding function is imparted by the tubular shielding member 50, and thus the path portion of the unshielded wire 30 can be maintained as a constant path.

[0062] In addition, by using the metal band 58 as the tubular shielding member 50, the path holding function and shielding property can be imparted to the conduction path of the unshielded wire 30 by a single member.

[0063] In addition, by making the portion protected by the tubular shielding member 50 in the wiring path be the unshielded core wire 32 made of aluminum or aluminum alloy, the wiring module 10 can be made low-cost and lightweight. Regarding the shielded wire 20, by using a core wire made of copper or copper alloy, it is easily bendable and the wiring workability is excellent.

[0064] In addition, if the unshielded core wire 32 is a solid conductor filled inside, the diameter of the unshielded wire 30 can be reduced, and it is easy for the unshielded wire 30 itself to have a path holding function.

[0065] In addition, if the end of the shielding portion 26 and the outer periphery of the end of the tubular shielding member 50 which is a tubular shielding portion overlap, and the end of the shielding portion 26 and the end of the tubular shielding member 50 are fastened by the metal band 58, the shielding portion 26 and the tubular shielding member 50 can be firmly fixed in an electrically connected state.

[0066] In addition, if two shielded wires 20 are connected to both ends of the unshielded wire 30, and two insulating members 40 and two water stoppage members 60 are respectively provided at both ends of the unshielded wire 30, even when the portion between the two shielded wires 20 is replaced with the unshielded wire 30, shielding property and path holding function can be imparted, and water stoppage property can be imparted to the connection part of the wires 20 and 30.

[0067] [Embodiment 2] The wiring module of Embodiment 2 will be described. Figure 3It is a cross-sectional view showing the wiring module 110 of Embodiment 2. In addition, in the description of this embodiment, the same reference numerals are assigned to the same components as those described in Embodiment 1, and their descriptions are omitted.

[0068] In this embodiment, as a member for fixing the shielding portion 26 to the end of the cylindrical shielding member 50, a tape 158 is used instead of the metal band 58. The tape 158 may also have an adhesive layer formed on one surface of the strip-shaped base material. The tape 158 may be a metal tape such as an aluminum tape or a resin tape such as a PVC tape. The tape 158 is wound in a spiral shape from the end of the shielding portion 26 to the end of the cylindrical shielding member 50. By fastening the end of the shielding portion 26 toward the cylindrical shielding member 50 with the tape 158 and pasting it to the outer surface of the end of the shielding portion 26 and the outer surface of the end of the cylindrical shielding member 50, the shielding portion 26 is maintained in a state of being in electrical contact with the cylindrical shielding member 50 and is maintained in a state of being fixed to the cylindrical shielding member 50.

[0069] In addition, in this embodiment, a water stop member 160 that is heat-shrunk by a heat-shrinkable tube is used instead of the water stop member 60. One end of the water stop member 160 covers the end of the shielding portion covering portion 28, and the other end of the water stop member 160 covers the outer periphery of the end of the cylindrical shielding member 50. The other end of the water stop member 160 is located at a position closer to the center of the cylindrical shielding member 50 than the tape 158.

[0070] In the heat-shrunk state, one end of the water stop member 160 fastens the end of the shielding portion covering portion 28, and the other end of the water stop member 160 fastens the end of the cylindrical shielding member 50. A hot melt adhesive may be provided inside the water stop member 160, and the hot melt adhesive seals between the heat-shrinkable tube and the shielding portion covering portion 28 or the cylindrical shielding member 50.

[0071] Through this wiring module 110, as with the above-mentioned wiring module 10, when connecting the non-shielded wire 30 and the shielded wire 20, the conductive path of the non-shielded wire 30 can be given shielding properties and a path holding function, and water tightness can be given to the connection portion of the wires 20 and 30.

[0072] [Embodiment 3] The wiring module 210 of Embodiment 3 will be described. Figure 4 It is a cross-sectional view showing the wiring module 210. In addition, in the description of this embodiment, the same reference numerals are assigned to the same components as those described in Embodiment 1, and their descriptions are omitted.

[0073] In the present embodiment, the cylindrical shielding member 250 is used instead of the cylindrical shielding member 50. The cylindrical shielding member 250 includes a cylindrical braid 252 as a cylindrical shielding portion and a resin tube 254 covering the cylindrical braid. The cylindrical braid 252 is a member formed by braiding metal wires into a cylindrical shape. The resin tube 254 may be a cylindrical resin component formed by extrusion molding or the like, or a component formed by combining semi-cylindrical components formed by die molding in a manner to form a cylinder.

[0074] The cylindrical braid 252 covers the unshielded electric wire 30. The resin tube 254 covers the cylindrical braid 252. Shielding property is obtained by the cylindrical braid 252. A path holding function is obtained by the resin tube 254. The resin tube 254 has a protection function and an insulating function with respect to the cylindrical braid 252.

[0075] The cylindrical braid 252 extends from the end of the unshielded electric wire 30 and covers the end of the shielding portion 26. In a state where the end of the shielding portion 26 overlaps with the inner periphery of the cylindrical braid 252 as the cylindrical shielding portion, the metal band 258 fastens the end of the shielding portion 26 and the end of the cylindrical braid 252. As the metal band 258, the same member as the above-described metal band 58 can be used.

[0076] According to this example, shielding property can be imparted to the unshielded electric wire 30 by the cylindrical braid 252, and a path holding function can be imparted by the resin tube 254.

[0077] In addition, also in the same manner as the above-described wiring module 10, by this wiring module 210, when connecting the unshielded electric wire 30 and the shielded electric wire 20, shielding property and a path holding function can be imparted to the conductive path of the unshielded electric wire 30, and water stoppage property can be imparted to the connection portion of the electric wires 20 and 30.

[0078] [Modification Example] In the above-described wiring module 10, as Figure 5 shown, the cylindrical shielding member 350 corresponding to the cylindrical shielding member 50 may also have a bent portion 352 bent at the intermediate portion in the extending direction. In Figure 5 , the intermediate portion of the cylindrical shielding member 350 has two bent portions 352 bent in opposite directions. The both end portions of the cylindrical shielding member 350 extend along the same direction, and the intermediate portion of the cylindrical shielding member 350 extends in a direction crossing the both ends. Therefore, by the cylindrical shielding member 350, the unshielded electric wire 30 can be held along a bent path. The cylindrical shielding member 250 of the third embodiment may also have a bent portion.
