{First embodiment}
Hereinafter, a method for manufacturing a roof wiring module, a roof wiring module, and an electric wire fixture according to an embodiment will be described.

<Overall configuration of roof wiring module>
FIG. 1 is a schematic exploded perspective view showing the roof wiring module 20 and its incorporation target.

  The body roof 10 that is an object to which the roof wiring module 20 is incorporated is a portion that covers the upper part of the passenger compartment of the vehicle body that forms the basic shape of the vehicle, and is formed in a plate shape from metal or the like. Pillars 12 that support the body roof 10 are provided at the corners and the like of the body roof 10.

  The roof wiring module 20 is attached to the inner surface side (the vehicle inner side) of the body roof 10. The roof wiring module 20 includes a roof panel 22, a wiring part 30, and an electric wire fixture 40.

  The roof panel 22 is a plate-shaped portion formed of a resin or the like, and is a portion called a roof garnish. Here, the roof panel 22 has a plate shape in which a peripheral portion curves downward. The roof panel 22 is attached so as to cover the inner surface side of the body roof 10. The wiring portion 30 and the electric wire fixture 40 are assembled to the surface on the body roof 10 side, which is one main surface side of the roof panel 22. The roof panel 22 is disposed in a space formed between the roof panel 22 and the body roof 10.

  The roof panel 22 has an electrical component mounting opening 23h. Here, an electrical component mounting opening 23h for mounting a room lamp or the like is formed at a position from the front of the central portion of the roof panel 22 and a position from the rear of the central portion. The wiring portion 30 incorporated in the roof panel 22 is used as an electrical wiring to electrical components attached to the roof panel 22 and electrical components around the roof panel 22.

  A plurality of wire fixing tools 40 are fixed to the surface (upper surface) on the body roof 10 side, which is one main surface of the roof panel 22. The wire fixture 40 is a member that is flexible and elastically deformable, and is a member in which at least one slit 44 is formed. The electric wire fixture 40 has a role of keeping the electric wire 32 in a bundled state and keeping the electric wire 32 in a predetermined position. The reason why the electric wire fixture 40 is configured to be flexible and elastically deformable is to allow the electric wire 32 to be easily inserted and held in the slit 44. As a material for manufacturing such an electric wire fixture 40, it is preferable to use a non-woven member and a foamed member (a foamed resin member, a foamed rubber member, etc.). Further, when the electric wire fixture 40 is formed so as to be flexible and elastically deformable, even when one main surface of the roof panel 22 forms a curved surface, the electric wire fixture 40 is surface-bonded to the one main surface of the roof panel 22. There is an advantage that the electric wire fixing device 40 can be accommodated in a compressed state in accordance with the gap shape between the roof panel 22 and the body roof 10, and excellent versatility.

  A more specific example of the wire fixture 40 will be further described later.

  The wiring portion 30 is configured by inserting a plurality of electric wires 32 into the respective slits 44 of the plurality of electric wire fixtures 40 fixed on the roof panel 22 and arranging them on the roof panel 22 while being bound together. Has been. The wiring part 30 may be held linearly in the electric wire fixture 40 or may be held while being branched. In any case, the wiring part 30 is held at a predetermined position on the roof panel 22 by being held by the electric wire fixture 40. In addition, when the plurality of electric wires 32 constituting the wiring unit 30 are inserted into the slits 44, the plurality of electric wires 32 are held in a state of being bundled with those inserted into the same slit 44. However, the wiring part 30 may be fixed on the roof panel 22 by an adhesive tape or the like at a portion other than the electric wire fixture 40 or may be bound.

  The wiring part 30 may be provided with an exterior part. As the exterior parts, a corrugated tube for protecting the wiring part 30, a clamping part for attaching the wiring part 30 to other parts of the vehicle body, and the like are assumed. In FIG. 1, a corrugated tube 38 is attached to a portion of the wiring portion 30 that extends outward from the roof panel 22.

  As described above, the wiring portion 30 is maintained along the predetermined path by the electric wire fixture 40 fixed on the roof panel 22, thereby configuring a wire harness that is a wiring material.

<Wire fixture>
FIG. 2 is a perspective view showing the electric wire fixture 40, and FIG. 3 is a schematic plan view showing a state where the wiring portion 30 is held by the electric wire fixture 40.

  The electric wire fixture 40 is configured by forming slits 44 in a thick nonwoven material (nonwoven sheet). The non-woven member is formed by intertwining many fibers without being woven. Such a non-woven member exhibits such flexibility that the slit 44 can be widened and the electric wire 32 can be disposed in the slit 44. In addition, in the state where the electric wire 32 is disposed in the slit 44, an elastic force that can be elastically restored so as to close the slit 44 is shown. In addition, since the non-woven member hardly generates sound even when it comes into contact with other members, there is a merit in terms of soundproofing measures.

  The fibers constituting the non-woven member may be any of natural fibers, synthetic resin fibers, glass fibers and the like. As will be described later, considering that the slit 44 of the electric wire fixture 40 is closed by heating, a non-woven member including a basic fiber and a binder resin having a melting point lower than that of the basic fiber is used as the non-woven member. Is preferred. The binder resin may be contained in the nonwoven member in any form of a fiber state, a state covering the basic fiber, and a grain state. When a non-woven member containing such a binder resin is heated at a temperature lower than the melting point of the basic fiber and higher than the melting point of the binder resin, the non-woven members are bonded to each other by the molten binder resin while maintaining a certain degree of flexibility. These contact portions can be joined, and the slit 44 can be closed.

  Here, the electric wire fixture 40 is formed in a rectangular parallelepiped shape, more specifically, a rectangular parallelepiped shape showing a square shape in plan view. The length dimension of one side of the electric wire fixture 40 in plan view may be about 100 mm, and the thickness size of the electric wire fixture 40 may be about 60 mm. The planar view shape of the electric wire fixture may be formed in other polygonal shapes or circular shapes.

  A slit 44 is formed on one main surface of the electric wire fixture 40. Here, the slits 44 are formed radially on one main surface of the wire fixture 40.

  More specifically, the plurality of slit portions 44a extend radially from the center of the wire fixture 40 in plan view. Each slit portion 44 a includes one extending from the center toward the four corners of the wire fixture 40 and one extending toward the center of the four sides of the wire fixture 40. That is, here, the slit 44 includes a slit portion 44 a extending in eight directions from the central portion of the wire fixture 40.

  The slits are not necessarily formed in a radial shape, and may be configured as simple linear or curved slits, or may be formed in a vertical and horizontal matrix. Moreover, even when the slits are formed in a radial pattern, the slits only need to extend radially in three or more directions. Further, as described above, it is not essential that the slit portions 44a extend radially at equal angles.

  The depth dimension of the slit 44 may be a dimension that can be fixed with the wiring portion 30 interposed therebetween. For example, the depth dimension may be about half the thickness dimension of the wire fixture 40. If the thickness dimension of the electric wire fixture 40 is 60 mm as in the above example, the depth dimension of the slit 44 may be 30 mm.

  The wiring portion 30 is maintained in a bundled state by being inserted into the slit 44 of the electric wire fixture 40 and is held at a predetermined position.

  With reference to FIG. 3, the relationship between the shape of the wiring part 30 and the electric wire fixture 40 is demonstrated.

  A slit portion 44a is provided on the opposite side of the center with respect to one slit portion 44a. Further, another slit portion 44a is provided at an angle of 45 °, 90 °, and 135 ° with respect to one slit portion 44a.

  Therefore, when the straight portion of the wiring portion 30 is held by the electric wire fixture 40, the wiring portion 30 may be inserted into the slit portion 44a extending in a straight line. Further, when there is another portion (a portion bent or bent with respect to the predetermined portion) with respect to the predetermined portion of the wiring portion 30, the predetermined portion is replaced with one slit portion 44 a. The other portion is inserted into another slit portion 44a according to the angle.

  Thereby, the other part of the wiring part 30 is held in any of a state in which it forms a straight line with respect to the predetermined part, and a state in which an angle of 45 °, 90 °, or 135 ° is formed. For this reason, the wiring part 30 can be held at a constant angle, or the branch portion of the wiring part 30 can be held at a constant angle.

  In addition, it is preferable that the opening side portion of the slit 44 is closed in order to prevent the wiring portion 30 from dropping in a state where the wiring portion 30 is inserted into the slit 44 of the electric wire fixture 40. When the wire fixture 40 is formed of a non-woven member containing a binder resin, it is easy to heat the portion of the wire fixture 40 on the opening side of the slit 44 (opening opposite to the bottom of the slit 44). The opening side portion can be closed. This will be described in detail later.

  As shown in FIG. 4, the other main surface of the electric wire fixture 40 (the surface opposite to the one main surface on which the slit 44 is formed) is fixed to the roof panel 22 by a joining member 48. Yes. As the joining member 48, a hot melt adhesive, a pressure-sensitive adhesive, an adhesive, a double-sided tape, or the like can be used.

  As shown in FIG. 5, in a state where the roof panel 22 is fixed to the body roof 10, the wire fixing tool 40 is sandwiched between the roof panel 22 and the body roof 10 and compressed (for example, a thickness of 60 mm). Sized wire fixture 40 is compressed to about 20 mm) and is more securely fixed in place between them in strong interference.

<Method for manufacturing roof wiring module>
A method for manufacturing the roof wiring module 20 will be described. FIG. 6 is a flowchart showing a manufacturing method of the roof wiring module 20, FIG. 7 is an explanatory view showing an example of a manufacturing method of the wire fixture 40, and FIGS. 7 to 10 show each manufacturing process of the roof wiring module 20. It is explanatory drawing.

  First, a plurality of wire fixtures 40 are prepared. The wire fixing tool 40 can be manufactured, for example, as shown in FIG. That is, the nonwoven sheet 40S wound and accommodated in a roll shape is drawn out and cut into a square shape. And the slit 44 is formed in the non-woven member formed in the square shape, and the electric wire fixing tool 40 is formed. The slit 44 can be formed, for example, by pressing a cutting blade against one main surface of the non-woven member and cutting it halfway in the thickness direction.

  The manufacturing method of the roof wiring module 20 includes a wire fixing device fixing step, a wire wiring step, an exterior component mounting step, and a slit closing step (see FIG. 5).

  In the electric wire fixing device fixing step, a plurality of electric wire fixing devices 40 are fixed to one main surface side of the roof panel 22 (see FIG. 8). That is, at the manufacturing work place of the roof wiring module 20, the roof panel 22 is supported at a fixed position with one main surface (the surface on the body roof 10 side) facing upward. Then, the worker P stands around the roof panel 22 and fixes the wire fixing tool 40 to the roof panel 22.

  Here, the case where the wiring part 30 is wired with respect to the roof panel 22 as follows is assumed. That is, the wiring part 30 passes through one side part (the right side in FIGS. 8 and 9) from the center part in the width direction of the longitudinal direction one end part (the end part on the vehicle front side, the lower side in FIGS. 8 and 9). The roof panel 22 is disposed so as to reach the center in the width direction of the other end portion in the longitudinal direction (the rear side of the vehicle, the upper side in FIGS. 8 and 9). Further, a part of the wiring portion 30 is drawn outward from one side portion of the other end portion in the longitudinal direction of the roof panel 22.

  The plurality of electric wire fixtures 40 have a width direction of one end portion in the longitudinal direction of the roof panel 22 (the end portion on the front side of the vehicle, the lower side in FIGS. 8 and 9) so as to hold the wiring portion 30 along the wiring path. Each position of the central part and one side part (right side in FIGS. 8 and 9), the position of the central part in the extending direction of one side part (right side in FIGS. 8 and 9) of the roof panel 22, It is fixed to the roof panel 22 at each position of the widthwise central portion and one side portion (the right side portion in FIGS. 8 and 9) of the other longitudinal end portion (the rear side of the vehicle, the upper side in FIGS. 8 and 9). The electric wire fixture 40 is fixed to the roof panel 22 via a hot melt adhesive or the like as described above.

  In the wire routing step, the plurality of wires 32 are inserted into the respective slits 44 of the plurality of wire fixtures 40, and the plurality of wires 32 are bound and arranged on the roof panel 22.

  The electric wires 32 are in a disjointed state where they are not bound. Terminals 33 may be connected to ends of the plurality of electric wires 32. Moreover, the some electric wire 32 may be combined with the form called the subassembly which comprises a part of one wire harness. For example, the plurality of electric wires 32 may be combined in a form called a sub-assembly by connecting the terminals 33 at the ends of the plurality of electric wires 32 to the common connector 34.

  The electric wire 32 is inserted into the slits 44 of the plurality of electric wire fixtures 40 along a predetermined wiring path. Here, the electric wire 32 is inserted into the slit 44 so as to bend at an angle of 90 degrees with respect to the electric wire fixture 40 at the center in the width direction at both longitudinal ends of the roof panel 22. Further, with respect to the electric wire fixture 40 on one side in the width direction (lower right side in FIG. 9) at one longitudinal end of the roof panel 22, the electric wire 32 is inserted into the slit 44 so as to be bent at an angle of 135 degrees. Is done. Moreover, the electric wire 32 is inserted in the slit 44 so that it may become linear form with respect to the electric wire fixing tool 40 of the intermediate part of the one side part (right side center part of FIG. 9) of the roof panel 22. FIG. Furthermore, the electric wire 32 is inserted into the slit 44 so as to bend at an angle of 90 degrees with respect to the electric wire fixture 40 on one side (upper right side in FIG. 9) of the other longitudinal end of the roof panel 22. At the same time, some of the electric wires are inserted into the slit 44 so as to extend outward at an angle of 135 degrees with respect to the other electric wires.

  The electric wires 32 are inserted into the slits 44 of the electric wire fixtures 40 so as to be kept in a bundled state and supported at a fixed position on the roof panel 22, thereby forming the wiring portion 30. The As described above, the plurality of electric wires 32 may be bound by an adhesive tape or the like at other portions, or may be fixed to the roof panel 22.

  The exterior component mounting process is a process of mounting the exterior component on the electric wire 32. Here, as described above, the corrugated tube 38 is mounted as an exterior part. Here, the corrugated tube 38 is attached to a portion of the wiring portion 30 that extends outward from one side portion of the other longitudinal end portion of the roof panel 22.

  The corrugated tube 38 may be attached to another part of the wiring part 30. Moreover, a clamp part for fixing the wiring part 30 to the vehicle body, a grommet for waterproofing, or the like may be attached to the wiring part 30.

  This exterior component mounting step may be performed during the operation of inserting the electric wires 32 into the slits 44 of the plurality of electric wire fixtures 40 or may be performed after the operations are completed.

  As described above, the roof panel 22 is handled in the same manner as a kind of wire harness assembly drawing board, and the electric wires 32 in a separate state are directly assembled to the roof panel 22 and bundled into a predetermined wiring form. Since the wiring is performed, the roof wiring module 20 can be easily manufactured.

  In the slit closing step, the openings of the slits 44 of the plurality of electric wire fixtures 40 (opening on the near side in the insertion direction of the electric wires 32 with respect to the slits 44, that is, the opening on the one main surface side of the electric wire fixture 40) are closed. Go. Here, the slit 44 is closed as shown in FIGS. That is, using the heating device 60 having a heating surface that has the same extent as the one main surface of the electric wire fixture 40, the one main surface of the electric wire fixture 40 is heated while being pressed. The heating device 60 includes a square-shaped heating plate 62 having the same size as the one main surface of the electric wire fixture 40 and a support portion 64 that supports the heating plate 62. The heating plate 62 is heated to a temperature equal to or higher than the melting point of the binder resin of the wire fixture 40 by a heater or the like. And in the state which inserted the electric wire 32 to the back of the slit 44, the said support part 64 is supported by the operator etc., and the heating plate 62 is pressed on one main surface of the electric wire fixture 40. FIG. Then, the one main surface of the electric wire fixture 40 is heated while the opening of the slit 44 is closed on the one main surface side of the electric wire fixture 40. As a result, the binder resin is melted mainly on one main surface of the electric wire fixture 40, and the melted binder resin joins the portions of the non-woven member to both sides of the opening of the slit 44. As a result, the opening of the slit 44 is closed.

  The opening of the slit 44 may be closed with another hot melt adhesive or the like. In this case, it is not necessary to block all the openings of the slits 44, and only the openings of the slits 44 into which the electric wires 32 are inserted may be blocked.

  However, as described above, if the heating device 60 having a heating surface having the same extent as the one main surface of the wire fixture 40 is used, all the openings of the radially formed slits 44 can be blocked together. it can. For this reason, it is convenient because the operation of closing the openings of the slits 44 can be performed collectively without worrying about which slit 44 the electric wire 32 is inserted into.

<Effects>
According to the manufacturing method of the roof wiring module 20 configured as described above, the roof wiring module 20, and the wire fixing tool 40, the plurality of wires 32 are fixed to the roof panel 22 on the roof panel 22. If it inserts in the slit 44 of the fixing tool 40, since the bundling and wiring operation | work of the some electric wire 32 can be performed, the roof wiring module 20 can be manufactured easily.

  That is, as a method of wiring electric wires on the roof panel, for example, a wire harness in which a plurality of electric wires are bundled in a form corresponding to a predetermined wiring form on a wire harness assembly work table is manufactured, and this is applied to the roof panel. The method of developing and assembling above is assumed. In this case, the work of spreading and binding the electric wires on the wire harness assembly work table and the work of deploying the wire harness on the roof panel and fixing it to the roof panel are performed as separate work in different places. There was a need. In particular, since the electric wires 32 arranged in the roof tend to be long, it is troublesome to handle a wire harness including such long electric wires as described above.

  However, according to the present embodiment, the bundling operation and the fixing operation can be performed by spreading the electric wires 32 directly on the roof panel 22 so that the roof panel 22 is used as a kind of wire harness assembly work table. For this reason, the roof wiring module 20 can be manufactured easily.

  Moreover, since the electric wire fixture 40 is comprised by the non-woven member, the said electric wire fixture 40 can be easily manufactured by cut | disconnecting a non-woven member suitably. In addition, the electric wire fixture 40 formed of a non-woven member can be easily deformed according to the degree of bending of the roof panel 22, the gap between the roof panel 22 and the body roof 10, etc., and thus has excellent versatility.

  Further, by closing the opening of the slit 44 of the wire fixing tool 40, it is possible to suppress the drop of the electric wire 32 from the wire fixing tool 40. In particular, when the wire fixing tool 40 is formed of a non-woven member containing a binder resin, the opening of the slit 44 can be easily blocked by heating the wire fixing tool 40 while maintaining the flexibility of the wire fixing tool 40. Can do.

  In addition, since the slits 44 are radially formed in the wire fixing tool 40, the wires 32 can be branched and bent in various directions by selectively inserting the wires 32 into the radially extending slit portions 44a. The electric wire 32 can be held in a predetermined wiring form corresponding to the shape easily. Also from this point, the electric wire fixture 40 is used as a versatile component.

  Moreover, the roof wiring module 20 with exterior parts can also be easily manufactured by attaching exterior parts, such as the corrugated tube 38, to the electric wire 32 on the roof panel 22.

  Moreover, the electric wire fixture 40 itself is a versatile component, and various roof wiring modules 20 can be manufactured by appropriately changing the fixing position of the electric wire fixture 40 according to the wiring form. .

  For example, as shown in FIG. 12, the length dimension of the roof panel 122 corresponding to the roof panel 22 is larger than the length dimension of the roof panel 22, and other electrical components are mounted on the roof panel 122. Even in such a case, it is possible to easily cope with the problem by increasing the interval between the wire fixing tools 40 or increasing the number of installation locations of the wire fixing tools 40. In the example shown in FIG. 12, the distance between the wire fixing tools 40 is increased in the longitudinal direction of the roof panel 122. In addition, an electric wire fixture 40 is additionally provided on the other side portion (the left side portion in FIG. 12) in the middle portion in the longitudinal direction of the roof panel 122.

  Further, as shown in FIG. 13, even when the length dimension of the roof panel 222 corresponding to the roof panel 22 is smaller than the length dimension of the roof panel 22, the distance between the electric wire fixtures 40 is reduced, or It is possible to easily cope with the problem by reducing the number of installation places of the wire fixing tool 40. In the example shown in FIG. 13, the electric wire fixture 40 is omitted in the longitudinal intermediate portion of the roof panel 222.

  In addition, even when the wiring paths of the electric wires 32 are different, it is possible to easily cope with the wiring paths of the other paths by appropriately changing the installation position of the electric wire fixture 40.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
