[0029] [Explanation of Embodiments of the Present Disclosure]

[0030] First, an embodiment of the present disclosure will be described by citing the following.

[0031] ​​The wiring member of the present disclosure is described below.

[0032] (1) A wiring member, comprising: a connector housing including a housing main body and a cover attached to the housing main body, the housing main body being formed with a housing groove that is open at one main surface and recessed toward the other main surface; a wire-like transmission member, an end portion of which is housed in the housing groove; and a filling member filled in the housing groove, the housing main body having a bottom wall portion and a side wall portion as wall portions of the housing groove, the cover having a cover main body portion that overlaps the one main surface of the housing main body and covers the housing groove, the filling member being further provided between a portion of the one main surface that is a terminal surface of the side wall portion and the cover main body portion. By providing the filling member also between the end surface of the side wall portion and the cover main body portion, water intrusion from the gap therebetween is also inhibited by the filling member. Thus, the connector in which the end portion of the wire-like transmission member is arranged between a plurality of members can be simply waterproofed.

[0033] (2) In the wiring member of (1), the filling member can also be provided between the bottom wall portion and the wire-like transmission member. Thus, the filling member can cover the entire periphery of the wire-like transmission member.

[0034] (3) In the wiring member of (2), the bottom wall portion can be provided with a gap forming portion that separates the wire-like transmission member from the bottom wall portion, and the filling member can be provided in a gap between the bottom wall portion formed by the gap forming portion and the wire-like transmission member. Thus, even if the filling material of the bottom wall portion and the wire-like transmission member is not prearranged, the filling material that is heated and melted can be caused to enter the gap between the bottom wall portion formed by the gap forming portion and the wire-like transmission member.

[0035] (4) In the wiring member of (2), the portion of the bottom wall portion in which the filling member is provided can be flat in the length direction of the housing groove. Thus, the filling member can be provided between the bottom wall portion and the wire-like transmission member without the gap forming portion, thereby simplifying the shape of the housing main body.

[0036] (5) In the wiring member of (1), the inner surface of the bottom wall portion and the outer surface of the wire-like transmission member can be formed in corresponding shapes, and the bottom wall portion and the wire-like transmission member can be in close contact without the filling member. Thus, even if there is no filling member between the bottom wall portion and the wire-like transmission member, the wiring member can be simply waterproofed.

[0037] (6) In the wiring member of any one of (1) to (5), the connector housing can include a plurality of the housing bodies stacked with the filling member provided between the housing bodies. Thus, the filling member can be used to prevent water from entering between the stacked connector bodies.

[0038] (7) In the wiring member of any one of (1) to (6), the filling member can adhere to the cover and the housing body to fix the cover to the housing body. Thus, a locking mechanism that mechanically fixes the cover to the housing body can be omitted or simplified.

[0039] (8) In the wiring member of (7), the cover and the housing body are adhered via the first and second adhering portions of the filling member. The first adhering portion is a portion where the end surface of the side wall portion and the cover body portion are adhered via the filling member. The second adhering portion has an adhering strength higher than that of the first adhering portion. Thus, the adhering strength of the cover to the housing body is improved, and a locking mechanism that mechanically fixes the cover to the housing body can be omitted or simplified.

[0040] (9) In the wiring member of any one of (1) to (8), the wiring member can further include a locking mechanism that fixes the housing body to the cover. The locking mechanism includes a locking portion provided to the housing body and a locked portion provided to the cover and locked to the locking portion. Thus, even when the filling member cannot be adhered to the cover and the housing body, the locking mechanism can be used to fix the housing body to the cover.

[0041] [Details of Embodiments of the Present Disclosure]

[0042] Examples of the wiring member of the present disclosure will be described below with reference to the drawings. The present disclosure is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the equivalent meaning and scope of the claims.

[0043] [Embodiment 1]

[0044] The wiring member 10 related to Embodiment 1 will be described below. Figure 1 is a perspective view of the wiring member 10 related to Embodiment 1. Figure 2 is a plan view of the wiring member 10 related to Embodiment 1. Figure 3 is a cross-sectional view taken along the III-III line of Figure 2 . Figure 4 is a cross-sectional view taken along the IV-IV line of Figure 2 .

[0045] The wiring member 10 includes a connector housing 20, a wire-like transmission member 40, and a filling member 60. Here, the wiring member 10 further includes a sheet member 70.

[0046] The connector housing 20 includes a housing main body 21 and a cover 30. The housing main body 21 and the cover 30 are members each of which is mold-formed using a resin having insulating properties, such as polybutylene terephthalate (PBT), as a material. The housing main body 21 and the cover 30 are attached after being molded separately from each other.

[0047] The housing main body 21 has three sets of faces toward three directions orthogonal to each other. Hereinafter, the three directions are each referred to as a height direction, a depth direction, and a width direction, and these directions also apply to the connector housing 20. One set of faces facing in opposite directions to each other in the height direction is referred to as one main face 21a and another main face 21b. One set of faces facing in opposite directions to each other in the depth direction is referred to as a front end face 21c and a rear end face 21d. One set of faces facing in opposite directions to each other in the width direction is referred to as a pair of side faces 21e.

[0048] At least one (here, a plurality of) accommodation grooves 22 are formed in the housing main body 21. The accommodation grooves 22 are open at one main face 21a and recessed toward another main face 21b. The accommodation grooves 22 extend in the depth direction. Both end portions of the accommodation grooves 22 in the depth direction each reach the front end face 21c and the rear end face 21d. Thus, the accommodation grooves 22 are open on three sides with respect to the housing main body 21. Of the three openings, the opening at one main face 21a is referred to as an upper opening, the opening at the front end face 21c is referred to as a front opening, and the opening at the rear end face 21d is referred to as a rear opening. The wire-like transmission member 40 accommodated in the accommodation groove 22 is drawn out to the outside of the housing main body 21 from the rear opening. The front opening is used to connect the end portion of the wire-like transmission member 40 accommodated in the accommodation groove 22 to an opposite-side transmission member. The plurality of accommodation grooves 22 are arranged in a row in the width direction. The housing main body 21 has a bottom wall portion 23 and a side wall portion 24 as wall portions of the accommodation grooves 22. The bottom wall portion 23 is a wall portion constituting the bottom of the accommodation groove 22. Here, the portion of the bottom wall portion 23 in which the filling member 60 is provided (the portion on the rear end face 21d side) is flat in the length direction of the accommodation groove 22. The portion of the bottom wall portion 23 on the front end face 21c side can also be formed with a protrusion or a recess, or the like, for being engaged with the terminal 50 in the depth direction to prevent detachment. The outer surface of the bottom wall portion 23 toward the side opposite to the accommodation groove 22 is another main face 21b. The side wall portion 24 is a wall portion formed on both sides of the accommodation groove 22. The side wall portion 24 protrudes from the bottom wall portion 23 in the height direction. The plurality of side wall portions 24 are arranged in the width direction. The outer surface of the side wall portion 24 located at the outermost side in the width direction among the plurality of side wall portions 24 is a pair of side faces 21e. In addition, the end face in the height direction of the plurality of side wall portions 24 is one main face 21a.

[0049] The cover 30 is attached to the case main body 21. The cover 30 has a cover main body portion 31. Here, the cover 30 also has a pair of side cover portions 32. The cover main body portion 31 overlaps one main face 21a of the case main body 21 and covers the upper opening of the accommodation groove 22. The end face of the side wall portion 24 and the cover main body portion 31 can be formed with a step portion in at least one of the end face of the side wall portion 24 and the cover main body portion 31 so as to be in contact on the front end face 21c side and separated on the rear end face 21d side. By separating the end face of the side wall portion 24 from the cover main body portion 31 on the rear end face 21d side, a space for placing the substrate B1 (refer to Figure 5 ) described later is ensured. The pair of side cover portions 32 protrude in the height direction from both sides of the cover main body portion 31. The pair of side cover portions 32 cover the pair of side faces 21e of the case main body 21. Here, the side faces 21e and the side cover portions 32 are uniformly flat, but can have a concave-convex shape. It can also be that a portion of the side face 21e along the depth direction protrudes in the width direction more than another portion and is provided with a step portion or the like.

[0050] Here, in order to fix the case main body 21 and the cover 30, a locking mechanism 34 is provided to the connector case 20. The locking mechanism 34 fixes the case main body 21 and the cover 30. The locking mechanism 34 includes a latching portion 35 and a latched portion 36. The latching portion 35 is provided to the case main body 21. The latched portion 36 is provided to the cover 30. The latched portion 36 is latched with the latching portion 35. One of the latching portion 35 and the latched portion 36 is a convex portion, and the other is a concave portion. Here, the latching portion 35 is the convex portion, and the latched portion 36 is the concave portion, but it can be the reverse.

[0051] More specifically, a convex portion is formed in the side face 21e, and a concave portion is formed in the side cover portion 32. The concave portion is formed in a through-hole shape. The convex portion is fitted and latched in the concave portion. Two sets of convex portions and concave portions are provided for one set of side faces 21e and side cover portions 32. The two sets of convex portions and concave portions are provided separately in the depth direction. One set of convex portions and concave portions can be provided for one set of side faces 21e and side cover portions 32.

[0052] The linear transmission member 40 is a member that transmits electricity or light. For example, the linear transmission member 40 is an electric wire 40 that transmits electricity or an optical fiber cable that transmits light. The linear transmission member 40 has a transmission line body 42 and a covering layer 44. The transmission line body is a portion that transmits electricity or light. The transmission line body 42 is, for example, a core wire 42 made of a conductor in the covered electric wire 40 or a core and a cladding in the optical fiber cable. The covering layer 44 is a member that covers around the transmission line body 42. The covering layer 44 can be formed, for example, by extrusion molding of a resin such as polyvinyl chloride (PVC) or polyethylene (PE) around the transmission line body 42. One linear transmission member can have a single transmission line body or a plurality of transmission line bodies. The linear transmission member can be a single wire or a composite of a plurality of wires (a cable in which twisted wires, a plurality of wires, are concentrated and covered with a sheath, etc.). Hereinafter, the linear transmission member 40 is described as the covered electric wire 40 (hereinafter, simply referred to as the electric wire 40).

[0053] A terminal crimping portion 46 is provided at the end portion of the electric wire 40. The terminal crimping portion 46 is a portion in which the terminal 50 is crimped to the electric wire 40. The terminal crimping portion 46 includes a core wire crimping portion 47 and a covering crimping portion 48. In more detail, at the end portion of the electric wire 40, the core wire 42 is exposed from the covering layer 44. The terminal 50 is, for example, formed by flexibly deforming a plate material having electrical conductivity. The terminal 50 has a wire barrel 52, an insulating barrel 54, and a counterpart side connecting portion 56. The wire barrel 52 is a portion that is crimped to the core wire 42 exposed from the covering layer 44. The portion of the wire barrel 52 crimped to the core wire 42 is provided as the core wire crimping portion 47. The electric wire 40 and the terminal 50 are electrically connected via the core wire crimping portion 47. The insulating barrel 54 is a portion that is crimped to the covering layer 44. The portion of the insulating barrel 54 crimped to the covering layer 44 is provided as the covering crimping portion 48. The counterpart side connecting portion 56 is a portion that is electrically connected to a counterpart side conductor. Here, the counterpart side connecting portion 56 is formed in a female terminal shape. Of course, the counterpart side connecting portion 56 can be formed in a male terminal shape or the like.

[0054] The end portion of the electric wire 40 is housed in the housing groove 22. Normally, the end portion of the electric wire 40 is inserted into the housing body 21 before the mounting cover 30 from the upper opening of the housing groove 22. The terminal crimping portion 46 is housed on the rear end face 21d side of the housing groove 22. The covering layer 44 extending from the terminal crimping portion 46 protrudes from the rear opening. Here, a portion of the covering layer 44 connected to the terminal crimping portion 46 is also housed on the rear end face 21d side of the housing groove 22. In the case where the counterpart side connecting portion 56 is in a female terminal shape, normally, the counterpart side connecting portion 56 is housed in the housing groove 22 without protruding from the front opening. In the case where the counterpart side connecting portion 56 is in a male terminal shape, normally, it protrudes to the outside of the housing groove 22 from the front opening.

[0055] Further, in Figure 4 In the illustrated example, the end portion of the electric wire 40 is housed in the housing groove 22 in a manner that the bottom portion of the terminal crimp portion 46 is on the bottom wall portion 23 side, but it is not necessary that it be this orientation. For example, it can also be that the end portion of the electric wire 40 is housed in the housing groove 22 in a manner that the bottom portion of the terminal crimp portion 46 is on the lid main body portion 31 side, that is, in an opposite orientation in the height direction. Figure 4 In the illustrated example, the end portion of the electric wire 40 is housed in the housing groove 22 in a manner that the bottom portion of the terminal crimp portion 46 is on the bottom wall portion 23 side, but it is not necessary that it be this orientation. For example, it can also be that the end portion of the electric wire 40 is housed in the housing groove 22 in a manner that the bottom portion of the terminal crimp portion 46 is on the lid main body portion 31 side, that is, in an opposite orientation in the height direction.

[0056] The filling member 60 is filled in the housing groove 22. The filling member 60 is also provided between the end surface of the side wall portion 24 and the lid main body portion 31. The filling member 60 has an inner side portion 62 and an outer side portion 64. The inner side portion 62 is connected to the outer side portion 64.

[0057] The inner side portion 62 is a portion that is located inside each of the plurality of housing grooves 22. The inner side portion 62 has a waterproof portion 63. The waterproof portion 63 plugs a gap between the linear transmission member 40 and the wall portion of the housing groove 22 in a portion of the housing groove 22 along the depth direction to suppress the intrusion of water. The inner side portion 62 can have only the waterproof portion 63, or can have a portion other than the waterproof portion 63. The portion other than the waterproof portion 63 is a portion that is provided in a manner that a gap remains between the linear transmission member 40 and the wall portion of the housing groove 22.

[0058] Here, the waterproof portion 63 plugs a gap between the linear transmission member 40 and the wall portion of the housing groove 22 at a position of the covering layer 44 that extends from the terminal crimp portion 46. The filling material in the waterproof portion 63 is provided at least between the linear transmission member 40 and the side wall portion 24 and between the linear transmission member 40 and the lid main body portion 31. Here, the filling material in the waterproof portion 63 is also provided between the bottom wall portion 23 and the linear transmission member 40. Thus, here, the waterproof portion 63 covers the linear transmission member 40 entirely around. The waterproof portion 63 can also be provided at a position of the terminal crimp portion 46, for example, at a position of the covering crimp portion 48.

[0059] The outer portion 64 is located outside the receiving groove 22. Here, the outer portion 64 has a first outer portion 65 and a second outer portion 66. The first outer portion 65 is located outside a main surface 21a along the height direction of the receiving groove 22. The first outer portion 65 extends along a main surface 21a of the housing body 21. The filling member 60 is formally divided into an inner portion 62 and a first outer portion 65 by the upper opening. A plurality of inner portions 62 are connected via the outer portion 64. A portion of the first outer portion 65 is the portion of the filling member 60 located between the end face of the sidewall portion 24 and the cover body portion 31. The second outer portion 66 is located outside the rear end face 21d along the depth direction. The second outer portion 66 may extend beyond the rear opening in both the height and width directions, and may also contact the edge of the rear opening at the rear end face 21d. The filling member 60 is formally divided into an inner portion 62 and a second outer portion 66 by the rear opening. The second outer portion 66 may also be omitted.

[0060] The range of the filling member 60 along the depth direction can be appropriately set, but here the range of the filling member 60 along the depth direction is set to the range from the rear end face 21d to the terminal crimping portion 46. In particular, here the range of the filling member 60 along the depth direction is set to the range from the rear end face 21d to the covered crimping portion 48.

[0061] The filler component 60 is a resin substrate B formed in sheet form (see reference). Figure 5 The resin material is heat-deformed into a shape corresponding to the receiving groove 22. This resin material is not particularly limited and can be appropriately set. Preferably, the melting point of the resin material of the filling member 60 is lower than that of the resin material of the connector housing 20. The melting point of the filling member 60 may also be lower than that of the coating layer 44 of the linear transmission member 40. The resin material of the filling member 60 may also be the same material as the coating layer 44 of the linear transmission member 40. The resin material of the filling member 60 may also be a different material from the coating layer 44 of the linear transmission member 40. The resin material of the filling member 60 may also be a resin material used in hot melt adhesives.

[0062] The sheet 70 holds the multiple wires 40 in a side-by-side arrangement. Each wire 40 is fixed to the sheet 70 while the multiple wires 40 are in this side-by-side arrangement, thereby maintaining this arrangement. For example, at the ends of the sheet 70, the multiple wires 40 can be arranged in the same order as in the connector housing 20. This facilitates the easy convergence of the ends of the multiple wires 40 into the corresponding receiving slots 22.

[0063] The fixing method of the sheet 70 to the electric wire 40 is not particularly limited, and for example, can be fusion, can be adhesion via an adhesive or a double-sided tape or the like, or can be mechanical fixation using a clip or a rivet or the like. In the case where the sheet 70 is fused to the electric wire 40, the sheet 70 preferably includes a fusion layer. The sheet 70 can have a one-layer configuration of only the fusion layer, or can have a multi-layer configuration of an additional layer stacked on the fusion layer. In the case where the sheet 70 has a multi-layer configuration of the fusion layer and the additional layer, it is sufficient that the fusion layer is exposed on at least one of the main surfaces 21a of the sheet 70.

[0064] The fusion layer is a layer that can be fused to the covering layer 44 of the linear transmission member 40. The fusion layer contains a resin material, and preferably contains a thermoplastic resin material. The resin material of the fusion layer is softened and fused to a fusion object. The kind of the resin material is not particularly limited, and PVC, PE, polypropylene (PP), polyethylene terephthalate (PET), or the like can be used. Preferably, the fusion layer and the covering layer 44 contain the same kind of resin material.

[0065] The additional layer is formed of a different material from the fusion layer, or has a different configuration. The additional layer improves the function that the fusion layer has, or adds a function that the fusion layer does not have to the sheet 70. In addition to the above-described materials explained for the fusion layer, the material constituting the additional layer can be a metal or the like. The configuration of the additional layer can be any of the above-described configurations explained for the fusion layer. The additional layer can be one layer, or two or more layers.

[0066] The configuration of each layer in the sheet 70 is not particularly limited. Each layer in the sheet 70 can be appropriately selected from, for example, a sheet having a uniform full section (also referred to as a non-foamed sheet or a solid sheet, or the like), a foamed sheet, a fiber material sheet, or the like. The fiber material sheet is a sheet in which fibers are combined, and is, for example, a woven cloth, a knitted cloth, or a non-woven fabric, or the like.

[0067] The sheet 70 can be a soft member. The sheet 70 can have flexibility that can conform to the flexure of the linear transmission member 40. The sheet 70 can be such that, in a spread state, flexure in the thickness direction (flexure around an axis parallel to the main surface of the sheet 70) is easy, and flexure in a direction intersecting the thickness direction (flexure around an axis perpendicular to the main surface of the sheet 70) is difficult.

[0068] The linear transmission member 40 is arranged on the fusion-bonded layer in the sheet 70. The linear transmission member 40 is fusion-bonded to the fusion-bonded layer. Thus, the linear transmission member 40 is held in a state of being arranged on the sheet 70 along a predetermined path. The predetermined path of the linear transmission member 40 on the sheet 70 is, for example, a path corresponding to a wiring path of the linear transmission member 40 in the vehicle. In this way, the linear transmission member 40 is held in a state of extending in correspondence with the path in the vehicle by the sheet 70, and thus, when the wiring member 10 is assembled in the vehicle, the linear transmission member 40 is easily arranged along the predetermined wiring path.

[0069] The predetermined path of the linear transmission member 40 on the sheet 70 includes one or both of a straight section and a curved section. The predetermined path of the linear transmission member 40 on the sheet 70 can include two straight sections and a curved section therebetween. In the case where a plurality of linear transmission members 40 are included, the paths of the plurality of linear transmission members 40 can be all the same, or the paths of a part of the linear transmission members 40 can be different from the paths of another part of the linear transmission members 40. In the case where the paths of a part of the linear transmission members 40 are different from the paths of another part of the linear transmission members 40, a branch portion at which a part of the linear transmission members 40 branches from another part of the linear transmission members 40 can be provided on the sheet 70. By providing the branch portion on the sheet 70, a part including the branch portion can also be held on the predetermined path. In the case where a plurality of linear transmission members 40 are included, a crossing portion at which the linear transmission members 40 cross each other can also be provided on the sheet 70.

[0070] The planar shape of the sheet 70 can be formed in a shape corresponding to the predetermined path of the linear transmission member 40 on the sheet 70. In the case where the predetermined path of the linear transmission member 40 includes a curved section, the planar shape of the sheet 70 can also be bent in correspondence with the curved section. In addition, in the case where the predetermined path of the linear transmission member 40 includes a branch portion, the planar shape of the sheet 70 can also be branched in correspondence with the branch portion. The sheet 70 can be formed such that a dimension along an extension direction of the linear transmission member 40 is larger than a dimension along a width direction of the linear transmission member 40.

[0071] The fusion-bonded portions of the sheet 70 and the linear transmission member 40 can be provided at a plurality of positions spaced apart in the extension direction of the linear transmission member 40. Each of the fusion-bonded portions in this case is a point fusion-bonded portion in the extension direction of the linear transmission member 40. The fusion-bonded portions of the sheet 70 and the linear transmission member 40 can be provided in a row in the extension direction of the linear transmission member 40.

[0073] Reference Figure 5 and Figure 6 An example of a manufacturing method of the wiring member 10 will be described.Figure 5 and Figure 6 is a schematic view showing a case where the wiring member 10 according to Embodiment 1 is manufactured. Figure 5 is an exploded perspective view of members constituting the wiring member 10.

[0074] In manufacturing the wiring member 10, first, as shown in Figure 5 , a tape-wired body, a base material B, a housing main body 21, and a cover 30 are prepared. In the tape-wired body, a plurality of electric wires 40 are fixed to a sheet 70 in a side-by-side state, and the end portions of the electric wires 40 are crimped with terminals 50. Further, although it is not necessary to fix the plurality of electric wires 40 to the sheet 70 in the side-by-side state to form the tape-wired body, by using the tape-wired body, it is easy to house the end portions of the electric wires 40 in the housing main body 21. The base material B is a member that is heat-deformed to become the filling member 60. The base material B is formed in a sheet shape. Here, two kinds of base materials Bl, B2 are prepared. The base material Bl has a length dimension (a dimension in a width direction of the housing main body 21) having a dimension corresponding to a width dimension of the housing main body 21 (here, the same dimension), and one piece is prepared. The base material B2 has a width dimension that is the same as or smaller than a width dimension of the housing groove 22, and a plurality of pieces are prepared.

[0075] The plurality of base materials B2 are placed on the bottom wall portions 23 of the plurality of housing grooves 22, respectively. In each of the housing grooves 22, the end portions of the electric wires 40 are placed on the base material B2. Then, the base material Bl is overlapped with one main face 21a of the housing main body 21. Then, the cover 30 is overlapped with the housing main body 21 and the locking mechanism 34 is locked. At this time, by the step portion provided to the connector housing, the end face of the side wall portion 24 is separated from the cover 30 on the rear end face 21d side, and thus, even if the base material Bl is provided between the end face of the side wall portion 24 and the cover 30, the locking mechanism 34 can be securely locked. As described above, the assembly work of the connector before heating of the base material B is completed, and as shown in Figure 6 , a state where the end portions of the electric wires 40 are sandwiched between the base materials Bl, B2 is obtained. In addition, a state where the base material Bl is sandwiched between the end face of the side wall portion 24 and the cover main portion 31 is obtained. Further, a part of the base materials Bl, B2 can also be compressed in the height direction.

[0076] In this state, as shown in Figure 6 , a gap is generated between the covering layer 44 and the side wall portion 24, and the like. In order to fill the gap, the base material B in the housing groove 22 is heated. Although the heating method is not particularly limited, for example, the base material B in the housing groove 22 can be heated by a heating device 80 from the outside of the connector housing 20 toward the rear opening of the housing groove 22 to perform hot air heating. In addition, for example, the base material B in the housing groove 22 can be heated by heating the connector housing 20 and conducting heat from the connector housing 20.

[0077] The substrate B in the heated accommodation groove 22 eventually softens and flows as indicated by an arrow to fill the gap between the coating layer 44 and the side wall portion 24. Then, as indicated by an arrow, the substrates Bl, B2 fuse and adhere to the side wall portion 24 and the coating layer 44 of the accommodation groove 22 and solidify, thereby forming a waterproof portion 63. In addition, even if the substrate Bl softens and flows, a portion between the end surface of the side wall portion 24 and the cover main body portion 31 remains and forms a first outer portion 65. Figure 6 Figure 3 As indicated by an arrow, the substrates Bl, B2 fuse and adhere to the side wall portion 24 and the coating layer 44 of the accommodation groove 22 and solidify, thereby forming a waterproof portion 63. In addition, even if the substrate Bl softens and flows, a portion between the end surface of the side wall portion 24 and the cover main body portion 31 remains and forms a first outer portion 65.

[0078] In addition, the range of softening and flowing of the substrate B is determined according to a heating condition or the like, and the shape of a portion other than the waterproof portion 63 in the inner portion 62 is not particularly limited in a range of at least avoiding a shape that becomes an obstacle to electrical connection between the counterpart side connecting portion 56 and the counterpart side conductor and electrical connection between the wire barrel 52 and the conductor-made core wire 42. For example, in the portion other than the waterproof portion 63 in the inner portion 62, the substrates Bl, B2 can also be a portion that fuses similarly to the waterproof portion 63. In the portion other than the waterproof portion 63 in the inner portion 62, the substrates Bl, B2 can also be a portion that does not fuse and remains.

[0079] Effects of Embodiment 1 and the like

[0080] According to the wiring member 10 configured in the above-described manner, by also providing the filling member 60 between the end surface of the side wall portion 24 and the cover main body portion 31, water is also suppressed from being infiltrated from the gap by the filling member 60. Thus, it is possible to easily waterproof the connector in which the end portion of the wire-like transmission member 40 is disposed between the housing main body 21 and the cover 30.

[0081] The waterproof portion 63 can adhere to the wall portion of the accommodation groove 22 and the cover main body portion 31. If the waterproof portion 63 adheres to the wall portion of the accommodation groove 22 and the cover main body portion 31, water is further suppressed from being infiltrated between the wall portion of the accommodation groove 22 and the cover main body portion 31 and the waterproof portion 63. Similarly, the waterproof portion 63 can adhere to the outer surface of the coating layer 44. If the waterproof portion 63 adheres to the outer surface of the coating layer 44, water is further suppressed from being infiltrated between the outer surface of the coating layer 44 and the waterproof portion 63. The waterproof portion 63 in the filling member 60 can be formed, for example, by heating and melting the sheet-like substrate B.

[0082] In addition, the filling member 60 is also provided between the bottom wall portion 23 and the wire-like transmission member 40. Thus, the filling member 60 can cover the entire periphery of the wire-like transmission member 40. ​

[0083] In addition, the portion of the bottom wall portion 23 in which the filling member 60 is provided is flat in the length direction of the accommodation groove 22. Thus, even if the gap-forming portion is not provided, the filling member 60 is provided between the bottom wall portion 23 and the linear transmission member 40, and the shape of the case main body 21 can be simplified. For example, in a state in which the end portion of the linear transmission member 40 is disposed on the base material B2 provided in advance to the bottom wall portion 23, the base material B2 can be heated and melted to form the filling member 60. In addition, for example, it can be that the linear transmission member 40 in which the base material B2 is wound is accommodated in the accommodation groove 22, and the base material B2 is heated and melted to form.

[0084] In addition, the locking mechanism 34 that fixes the case main body 21 and the lid 30 is further provided. Thus, even if the filling member 60 is difficult to adhere to the case main body 21 and the lid 30, the case main body 21 and the lid 30 can be fixed by the locking mechanism 34. Further, the fixation of the locking mechanism 34 can also be used for temporary holding between the case main body 21 and the lid 30 at the time of heating of the base material B.

[0085] [Embodiment 2]

[0086] The wiring member relating to Embodiment 2 will be described. Figure 7 is a cross-sectional view that shows the wiring member 110 relating to Embodiment 2. Figure 8 is a schematic view that shows a case where the wiring member 110 relating to Embodiment 2 is manufactured. In addition, in the description of the present embodiment, the same components as those described so far are denoted by the same reference numerals and the description thereof is omitted. The same applies to the description of each of the following embodiments.

[0087] The wiring member 110 of the present example differs from the above-described wiring member 10 in that the connector is a stacked connector. The connector housing 120 includes a plurality of case main bodies 21, 121. The plurality of case main bodies 21, 121 are stacked. The lid 30 is attached to the uppermost case main body 121. With respect to the case main body 21 below that, the case main body 121 stacked above replaces the lid 30.

[0088] At this time, the lowermost housing body 21 can be the same as the housing body 21 in Embodiment 1. The upper housing body 121 is configured to also serve as a cover for the lower housing body 21. That is, the housing body 121 has a main body portion 27 and a cover portion 28. The main body portion 27 is formed with the same shape as the housing body 21. The cover portion 28 is formed with the same shape as the side cover portion 32 in Embodiment 1 and is provided on the side of the main body portion 27. A locking portion 35 is provided in the main body portion 27 and a locked portion 36 is provided in the cover portion 28. The locking portion 35 of the main body portion 27 is locked with the locked portion of the upper housing body or the locked portion 36 of the cover 30. The locked portion 36 of the cover portion 28 is locked with the locking portion 35 of the lower housing body 21.

[0089] In addition to being disposed between the housing body 21 and the cover 30, the filling member 60 is also disposed between the housing bodies 21 and 121. The filling member 60 disposed between the housing bodies 21 and 121 can be formed with the same structure as the filling member 60 disposed between the housing body 21 and the cover 30.

[0090] When manufacturing wiring component 110, such as Figure 8 As shown, the number of sheet wiring components and substrate B prepared is the same as the number of layers in the laminated connector. Then, similar to the wiring component 10 described above, the connector can be assembled before heating the substrate B, and then the substrate B is heated and melted to become the filler component 60.

[0091] According to the wiring component 110 in this example, the connector is a stacked connector, and a filling component 60 is also provided between the housing bodies 21 and 121, so that the layers of the stacked connector can be waterproofed by the filling component 60.

[0092] [Implementation Method 3]

[0093] The wiring components involved in Embodiment 3 will be described. Figure 9 This is a cross-sectional view showing the wiring component 210 according to Embodiment 3. Figure 10 This is a schematic diagram illustrating the case of manufacturing the wiring component 210 according to Embodiment 3.

[0094] In this example, the filling member 260 has adhesiveness. The filling member 260 adheres to the lid 230 and the case main body 221 to fix the lid 230 to the case main body 221. Thus, the locking mechanism 34 that mechanically fixes the lid 230 to the case main body 221 can be omitted or simplified. Here, the case main body 221 and the lid 230 are fixed by the locking mechanism 34 on the front end face 21c side and are fixed by the filling member 260 having adhesiveness on the rear end face 21d side. As in Embodiment 1, the fixing by the locking mechanism 34 can also be used to temporarily hold the lid 230 to the case main body 221 when the base material B is heated.

[0095] For example, in the portions of the lid 230 and the case main body 221 that are fixed by the locking mechanism 34 and the portions that are adhered by the filling member 260, the fixing force of the former can be smaller than that of the latter, or the fixing force of the latter can be smaller than that of the former. The fixing force refers to the force with which the lid 230 and the case main body 221 are separated when a force in the opposite direction is applied to them in the height direction. The fixing force of the portion fixed by the locking mechanism 34 and the fixing force of the portion adhered by the filling member 260 can be measured in a state where the fixing of either is performed and the fixing of the other is not performed. It is also possible to omit the locking mechanism 34 on the front end face 21c side and fix the case main body to the lid by the filling member 260 having adhesiveness.

[0096] At this time, the wiring member 210 is provided with a first adhered portion BP1 and a second adhered portion BP2 where the lid 230 and the case main body 221 are adhered by the filling member 260. The first adhered portion BP1 is a portion where the end face of the side wall portion 24 and the lid main body portion 31 are adhered by the filling member 260. The second adhered portion BP2 is a portion having a higher adhesive strength than that of the first adhered portion BP1. Thus, the adhesive strength of the lid 230 to the case main body 221 is increased, and the locking mechanism 34 that mechanically fixes the lid 230 to the case main body 221 can be omitted or simplified. As a case where the locking mechanism 34 is simplified, for example, a structure having a smaller locking force can be employed as the locking mechanism 34. In addition, for example, a positioning mechanism can be employed instead of the locking mechanism 34.

[0097] In this example, the first adhesive portion BP1 is the part where the end face of the sidewall portion 24 between the plurality of receiving grooves 22 is bonded to the cover body portion 31 via the filling member 60. The second adhesive portion BP2 is located outside the outermost receiving groove 22 in the width direction. Here, a flange 29 is provided on the housing body 21. The flange 29 is configured to protrude from a pair of side surfaces 21e in the width direction. A flange 33 is also provided on the cover 30 at a position corresponding to the flange 29. The part where the two flanges 29 and 33 are bonded via the filling member 60 is the second adhesive portion BP2. In both the first adhesive portion BP1 and the second adhesive portion BP2, the filling member 60 is made of the same material. Therefore, in both the first adhesive portion BP1 and the second adhesive portion BP2, the adhesive strength per unit area is the same. However, the area per unit length along the depth direction of the opposing portions of the two flanges 29 and 33 is greater than the area per unit length along the depth direction of the portion of the sidewall portion 24 opposite to the cover body portion 31. Therefore, the bonding area of ​​the second bonding part BP2 is larger than that of the first bonding part BP1. Even if the bonding strength per unit area is the same, the larger the bonding area, the higher the bonding strength.

[0098] Alternatively, by using a different adhesive in the first bonding portion BP1 and the second bonding portion BP2, the bonding strength per unit area can also be improved. Alternatively, by providing a recess in the second bonding portion BP2 where a fluid adhesive can penetrate and a cured adhesive can be held, the bonding strength can also be improved.

[0099] When manufacturing wiring component 210, such as Figure 10 As shown, a sheet-type wiring assembly, substrates B2 and B3, a housing body 221, and a cover 230 are prepared. Here, the length dimension of substrate B3 (the dimension in the width direction of housing body 221) in this example is longer than the length dimension of substrate B1 in Embodiment 1. In this example, substrate B3 has a length dimension corresponding to the width dimension of the portion of housing body 221 in which a pair of flanges 29 are formed. Then, similar to the wiring assembly 10 described above, the connector can be assembled before heating substrates B2 and B3, and then substrates B2 and B3 can be heated and melted to become a filling member 260.

[0100] [Implementation Method 4]

[0101] The wiring components involved in Embodiment 4 will be described. Figure 11 This is a cross-sectional view showing the wiring component 310 according to Embodiment 4. Figure 12 This is a schematic diagram illustrating the case of manufacturing the wiring component 310 according to embodiment 4.

[0102] In this example, in the waterproof section 363, there is no resin material forming a filler member 360 between the bottom wall portion 323 and the linear transmission member 40. In the waterproof section 363, by ensuring the bottom wall portion 323 is in close contact with the linear transmission member 40, waterproofing is possible even without the resin material forming a filler member 360 between the bottom wall portion 323 and the linear transmission member 40. Therefore, waterproofing can be easily achieved even without the resin material forming a filler member 360 between the bottom wall portion 323 and the linear transmission member 40.

[0103] More specifically, in the housing body 321, the inner surface of the bottom wall portion 323 is formed into a shape corresponding to the outer surface of the linear transmission member 40. Here, both the inner surface of the bottom wall portion 323 and the outer surface of the linear transmission member 40 are formed into circular shapes. Furthermore, the bottom wall portion 323 and the linear transmission member 40 are not tightly attached to each other via the resin material constituting the filling member 360.

[0104] Here, the inner surface of the bottom wall portion 23 is in close contact with the outer surface of the covering layer 44. Alternatively, the rubber stopper can be placed over the linear transmission member 40, so that the inner surface of the bottom wall portion 23 is in close contact with the outer surface of the rubber stopper.

[0105] In manufacturing the wiring component 310, in addition to the sheet wiring body, the housing body 321, and the cover 30, the base material such as Figure 12 As shown, substrate B2 is omitted and only substrate B1 is prepared. Then, similar to the wiring component 10 described above, the connector can be assembled before substrate B1 is heated, and then substrate B1 is heated and melted to become filler component 360.

[0106] [Variation Example]

[0107] Figure 13 and Figure 14 This is a cross-sectional view showing a modified example of the wiring component 10.

[0108] exist Figure 13 The wiring component 410 shown and Figure 14 In the wiring component 510 shown, gap forming portions 25 and 26 are provided on the bottom wall portion 23 to separate the linear transmission member 40 from the bottom wall portion 23. A filling member 60 is provided in the gap between the bottom wall portion 23 formed by the gap forming portions 25 and 26 and the linear transmission member 40. Therefore, even if no filling material (e.g., the aforementioned substrate B2) is pre-placed between the bottom wall portion 23 and the linear transmission member 40, a material formed by heating and melting the filling material (e.g., the aforementioned substrate B1) can be inserted into the gap between the bottom wall portion 23 formed by the gap forming portions 25 and 26 and the linear transmission member 40.

[0109] Figure 13The illustrated example is one in which the gap-forming portion 25 is a rib portion 25. In this case, the gap between the bottom wall portion 23 formed by the gap-forming portion 25 and the wire-shaped transmission member 40 is a portion located adjacent to the rib portion 25 in the depth direction. Further, in the illustrated example, the gap-forming portion 26 is a groove 26. In this case, the groove 26 itself is the gap between the bottom wall portion 23 formed by the gap-forming portion 26 and the wire-shaped transmission member 40. Figure 13 In the illustrated example, the rib portion 25 is provided only one, but the rib portion 25 can be provided two or more spaced apart in the depth direction. Figure 14 The illustrated example is one in which the gap-forming portion 26 is a groove 26. In this case, the groove 26 itself is the gap between the bottom wall portion 23 formed by the gap-forming portion 26 and the wire-shaped transmission member 40. The gap-forming portions 25, 26 can form a gap at a position of the covered layer 44 extending out of the terminal crimping portion 46 in the wire-shaped transmission member 40. In the case where the gap-forming portion 25 is a rib portion 25, the rib portion 25 can be formed at a position of the covered layer 44 extending out of the terminal crimping portion 46.

[0110] The gap-forming portions 25, 26 can be configured to form a gap between the wire-shaped transmission member 40 and the bottom wall portion 23 and between the wire-shaped transmission member 40 and the side wall portion 24. For example, the rib portion 25 and the groove 26 can be provided in series along the circumference of the inner surface of the accommodation groove 22. That is, the rib portion 25 and the groove 26 can extend from the end portion of one side wall portion 24 to the end portion of the other side wall portion 24 via the bottom wall portion 23. The height dimension of the rib portion 25 and the depth dimension of the groove 26 are not particularly limited as long as they are sizes into which the flowing filler member 60 can be immersed, and can be appropriately set. The gap-forming portions 25, 26 can be configured to form a gap at least between the wire-shaped transmission member 40 and the bottom wall portion 23, and the rib portion 25 and the groove 26 can be formed only in the bottom wall portion 23.

[0111] Further, both the rib portion 25 and the groove 26 can be provided as the gap-forming portion in one housing body. For example, two rib portions 25 can be formed spaced apart in the depth direction, and a groove 26 can be formed between the two rib portions 25.

[0112] Further, the structures explained in the above-described embodiments and modifications can be appropriately combined as long as they do not contradict each other.
