[0022] [Description of embodiments of this disclosure]

[0023] First, let's illustrate the implementation forms of this disclosure.

[0024] The door wiring module disclosed herein is as follows.

[0025] (1) A wiring module for a vehicle door includes: an access cover, comprising a cover body and a path indicator provided on the cover body; a wiring member whose path is restricted to pass through a first position and a second position on the cover body, the path indicator indicating multiple paths of different lengths as the path of the wiring member between the first position and the second position, the wiring member being restricted to pass through any one of the multiple paths. The path indicator indicating multiple paths of different lengths as the path of the wiring member between the first position and the second position, the wiring member being restricted to pass through any one of the multiple paths. Thus, for example, by using the longest wiring member among multiple door specifications and setting its path as any one of the multiple paths, it is possible to accommodate multiple door specifications. Thus, the access cover and the wiring member can be made into a shared component.

[0026] (2) In the door wiring module of (1), the path indicator may include a plurality of slots, which are formed to extend along the plurality of paths on the main surface of the cover body and to house the wiring component. Thus, the wiring component can be easily configured along a predetermined path by being housed in a predetermined slot.

[0027] (3) In the door wiring module of (1) or (2), the path indicator may include a fixing part formed on the main surface of the cover body at a position corresponding to each of the plurality of paths, and fixing the wiring member thereon. Thus, the wiring member is easily held in a state where the path is restricted to a predetermined path by being fixed by the predetermined fixing part.

[0028] (4) In any of the door wiring modules in (1) to (3), the path indicator may include a mark formed on the main surface of the cover body at a position corresponding to each of the plurality of paths. Thus, the wiring components are arranged along the prescribed marks, thereby facilitating their arrangement along the prescribed paths.

[0029] (5) In any of the door wiring modules in (1) to (4), the wiring component may be restricted to a path that passes through a first path among the plurality of paths, and the door wiring module may also include a dedicated wiring component that is restricted to a path that passes through a second path among the plurality of paths. For example, as the wiring component passing through the first and second positions, there may be dedicated wiring components specifically designed for the specifications of the plurality of doors and universal wiring components that are common to the specifications of the plurality of doors. In this case, by changing the path of the universal wiring component, the dedicated wiring component and the universal wiring component can be easily configured along a predetermined path on the access cover.

[0030] (6) Furthermore, the access cover of this disclosure includes a cover body and a path indicator provided on the cover body. The path indicator shows multiple paths of different lengths as paths between the first and second positions of a wiring member arranged to pass through the first and second positions on the cover body. Thus, for example, by using the longest wiring member among multiple door specifications and setting its path as any path selected from the multiple paths, it is possible to accommodate multiple door specifications. Therefore, the access cover and the wiring member can be made into a shared component.

[0031] (7) Furthermore, the manufacturing method of the wiring module for vehicle doors disclosed herein includes: a preparation step, preparing an access cover having a cover body and a path indicator provided on the cover body; and a path limiting step, limiting the path of the wiring component to pass through a first position and a second position on the cover body, wherein the path indicator shows multiple paths of different lengths as paths between the first position and the second position, and in the path limiting step, limiting the path of the wiring component to pass through any one of the multiple paths shown by the path indicator as a path between the first position and the second position. The path indicator shows multiple paths of different lengths as paths between the first position and the second position, and in the path limiting step, limiting the path of the wiring component to pass through any one of the multiple paths shown by the path indicator as a path between the first position and the second position. Thus, for example, by using the longest wiring component among multiple door specifications and setting its path to any one of the multiple paths selected from the multiple paths, it is possible to accommodate multiple door specifications. Thus, the access cover and the wiring component can be made into a shared component.

[0032] [Details of the embodiments of this disclosure]

[0033] Hereinafter, with reference to the accompanying drawings, specific examples of the wiring module for vehicle doors of this disclosure are described. It should be noted that this disclosure is not limited to these examples, but is disclosed by the scope of the claims, and includes all modifications within the scope of the claims.

[0034] [Implementation Method 1]

[0035] The following describes the wiring module for the car door according to Embodiment 1. Figure 1 This is a top view showing the door wiring module 30 of Embodiment 1 and the door panel 20 on which the door wiring module 30 is installed. Figure 2 yes Figure 1A sectional view along line II-II.

[0036] First, let's describe the general outline of the vehicle door 10. The door 10 is formed as a single unit with a flat shape and is a component in the vehicle that separates the interior from the exterior and is designed to be opened and closed. It is conceivable that the door 10 could be a driver's side door, a passenger side door, or a rear seat door, etc. The door 10 includes a door panel 20, exterior trim pieces, and a door wiring module 30.

[0037] The door panel 20 includes an outer panel 21 and an inner panel 22. The outer panel 21 is located in the door 10 facing outwards and forms part of the vehicle's exterior along with the body body. The inner panel 22 is located on the passenger side of the outer panel 21. The inner panel 22 has a side panel portion 23 and a main panel portion 25. The side panel portion 23 is a portion that protrudes from the outer panel 21 toward the passenger interior. The main panel portion 25 is connected to the side panel portion 23, is a portion that is spaced apart from the outer panel 21, and extends along the outer panel 21. A space is formed between the outer panel 21, the main panel portion 25, and the side panel portion 23. A door device provided in the door 10 or a window glass is housed in this space. An access hole 26 is provided in the main panel portion 25 of the inner panel 22. An operator can access the space between the outer panel 21 and the inner panel 22 from the outside of the inner panel 22 through the access hole 26. In this example, an example with two access holes 26 provided in the inner panel 22 will be described. It should be noted that the two access holes 26 can have the same or different planar shapes. Furthermore, the two access holes 26 can be arranged along the front-rear direction of the vehicle, but they can also be arranged along the height direction of the vehicle, or along an inclined direction that intersects with both the front-rear and height directions.

[0038] The exterior trim piece is the portion of the door 10 facing the interior of the vehicle, constituting part of the vehicle's interior appearance. Features such as interior handles and controls for in-vehicle equipment are installed on the exterior trim piece. The portion of the door wiring module 30 that is inserted into the door 10 is positioned between the exterior trim piece and the outer panel 21.

[0039] The door wiring module 30 includes an inspection hole cover 40, wiring components 50, and wiring cover 60.

[0040] A access cover 40 covers the access hole 26. Here, the two access holes 26 are each covered by a different access cover 40. Therefore, the door wiring module 30 here has two access cover 40s. Hereinafter, when it is necessary to distinguish between the two access cover 40s, the symbols A and B are sometimes added, referring to them as access cover 40A and 40B. Furthermore, when it is not necessary to distinguish between the two access cover 40A and 40B, they are sometimes simply referred to as access cover 40. However, it is also possible for one access cover to cover both access holes 26.

[0041] The access cover 40 is a flat resin component that is expanded to the same extent as or larger than the corresponding access hole 26. The access cover 40 is installed to close the access hole 26. With the access cover 40 installed in the access hole 26 of the inner plate 22, this installation is maintained by threaded fastening, locking mechanisms, or bonding. For example, if the portion of the periphery of the access cover 40 that overlaps with the inner plate 22 is bonded to the inner plate 22, the gap between them can be closed as much as possible.

[0042] The access cover 40 separates the interior space between the outer panel 21 and the inner panel 22. This space accommodates window glass exposed to rain, and a slit-like opening for the window glass to pass through is formed above this space. Therefore, this space is susceptible to water intrusion. Furthermore, this space is also potentially connected to the outside environment, making it a space where external noise such as wind noise can easily intrude. Therefore, the access cover 40 can be provided as a component that, together with the inner panel 22, more completely separates the interior space from the exterior space. More specifically, the access cover 40 includes a cover body 41, a frame 42, a flange 43, and a path indicator. For example, the access cover 40 is a component molded from resin such as polypropylene (PP), possessing rigidity that is difficult to bend.

[0043] The cover body 41 is a plate-shaped portion that extends slightly smaller than the access hole 26. The frame portion 42 is formed to protrude from the outer edge of the cover body 41 toward a main surface 41a (inside the vehicle interior) of the cover body 41. The flange portion 43 is formed to extend outward from the outer edge of the frame portion 42. The frame portion 42 can be formed as an inclined surface with its height decreasing sequentially from the flange portion 43 toward the cover body 41. When the access hole cover 40 is installed in the designated position of the access hole 26 in the inner panel 22, the cover body 41 is disposed inside the access hole 26 (toward the outer panel 21 than the main panel 25), the flange portion 43 is disposed outside the access hole 26 (toward the inside of the vehicle interior than the main panel 25), and the frame portion 42 connects the two. Thus, the periphery of the cover body 41 and the opening edge of the access hole 26 are closed by the frame portion 42 and the flange portion 43.

[0044] A groove 44 is formed on the main surface (main surface 41a of the cover body 41) of the access cover 40. Here, the groove 44 is formed on the main surface 41a of the access cover 40 facing the interior of the vehicle. The groove 44 may also be formed on the main surface 41b of the access cover 40 facing the exterior of the vehicle. The groove 44 may also be formed on both main surfaces 41a and 41b.

[0045] The slot 44 is sized to accommodate multiple wiring components 50 together. The slot 44 is flat, and its width is greater than its depth. The depth of the slot 44 can be greater than the diameter of the wiring component 50 (the diameter of the largest wiring component 50 in the case of multiple wiring components 50 containing wiring components of different thicknesses). To accommodate wiring components 50 stacked in two or more layers, the depth of the slot 44 can be more than twice the diameter of the wiring component 50 (the diameter of the smallest wiring component 50 in the case of multiple wiring components 50 containing wiring components of different thicknesses). Alternatively, the slot 44 can be formed in multiple rows to accommodate multiple wiring components 50 separately. For example, it can be formed in multiple rows to accommodate wiring components 50 one by one.

[0046] In the main surface 41b opposite to the main surface 41a where the groove 44 is formed, the portion opposite to the groove 44 is provided as a raised section 48. This helps to suppress the reduction in thickness of the portion where the groove 44 is formed. However, in the main surface 41b, the portion opposite to the groove 44 may not be provided as a raised section 48. Alternatively, in the main surface 41b, the portion opposite to the groove 44 and its surrounding portion may be flat.

[0047] The groove 44 of the inspection hole cover 40B functions as a path indicator.

[0048] A through hole 49 is formed in the access cover 40A for the wiring member 50 to pass through. The wiring member 50 passes through the through hole 49 and penetrates the access cover 40. The through hole 49 can be formed in the cover body portion 41 or the frame portion 42 of the access cover 40. Here, the through hole 49 is formed in the frame portion 42. In particular, the through hole 49 is formed at the end of the groove 44 in the frame portion 42. Thus, the wiring member 50, which is housed in the groove 44, can pass through the through hole 49 and penetrate the access cover 40.

[0049] The wiring component 50 connects the door equipment to body equipment installed on the vehicle body, supplying power to the door equipment or transmitting signals between the door equipment and the body equipment. The wiring component 50 may include wires 52. As wires 52, a sheathed wire with a sheath forming around a core wire composed of conductors can be used. The core wire can be a single-core wire or a twisted wire. The type of wire 52 is not particularly limited and may include single-wire, composite wire, etc. A single-wire wire is a wire with one conductive path. A composite wire is a wire with multiple conductive paths. As a composite wire, it can be a wire formed by combining multiple single wires, such as stranded wire or composite cable. The wiring component 50 may include fiber optic cables, etc. The number of wiring components 50 is determined according to the number of door equipment, etc. Typically, multiple wiring components 50 are provided.

[0050] The paths of the multiple wiring components 50 are appropriately set according to the specifications of the door 10. For example, in the case of a typical hinged door where the rotation axis is along the height direction of the vehicle, the multiple wiring components 50 assembled on the hinged door are usually connected to the vehicle body near the door hinge, and branch out to connect to various door devices as they move from the door hinge side toward the opposite side of the door hinge.

[0051] More specifically, consider the following scenario: one end of multiple wiring components 50 is bundled together, passing through a portion of the door 10 (in... Figure 1 In the example shown, the side panel 23 on the hinge side of the door extends from the door 10, is guided into the vehicle body, and connects to body equipment via a common connector C1 or the like, or to a relay connector provided at the end of a wiring component extending from the body equipment. The aforementioned body equipment is not particularly limited, and examples such as an electronic control unit (ECU) or a battery are conceivable. A cable ring G is typically installed on the portion of the plurality of wiring components 50 extending between the door 10 and the vehicle body. Figure 1 In the example shown, the cable loop G is a so-called through-type cable loop that is inserted and locked into a through hole formed in the side plate portion 23. This prevents water from seeping through the through hole. The cable loop G can also be a so-called non-through type cable loop that fits into a recess formed at the edge where the side plate portion 23 and the main plate portion 25 intersect. Multiple wiring components 50 extend from the cable loop G midway from one end to the other, branching and extending toward the door equipment that becomes their respective connection destination. Connectors C2 and C3 corresponding to the door equipment that becomes the connection destination are installed at the other ends of the multiple wiring components 50. Each connector C2 and C3 connects to, for example, connectors C4 and C5 on the door equipment side. Figure 1 and Figure 2 The diagram illustrates connectors C4 and C5 on the two door device sides, and wires 52A and 52B connected to connectors C4 and C5 via connectors C2 and C3. Connector C4 is, for example, a connector for a footlight. Connector C5 is, for example, a connector for an actuator used to lock and unlock the door 10.

[0052] exist Figure 1 and Figure 2 In the description of the door wiring module 30, connectors other than connectors C1-C3 and the wires 52A and 52B connected to them, as well as wiring components 50, are omitted. Of course, the door wiring module 30 may include connectors other than connectors C1-C3, and may also include wiring components 50 other than wires 52A and 52B. Hereinafter, when it is not necessary to distinguish between wires 52A and 52B, they may be referred to simply as wire 52.

[0053] The section of wire 52 extending between the grommets G and the access cover 40 can be configured as a bundled section bound by a bundling member. Figure 1In the example shown, adhesive tape T is wound into a spiral shape, and multiple wires 52 are bundled together. The bundling component can be a bundling strap, a flexible sheet, or a corrugated tube, etc. The bundling component can bundle multiple wires 52 in a flexible manner.

[0054] The wire 52 passes through the insertion hole 49 and through the access cover 40A midway from the portion with the grommets G toward the connectors C2 and C3, and moves toward the interior side of the inner panel 22 closer to the vehicle interior than the access cover 40A. The wire 52 can also pass through holes other than the access hole 26 in the inner panel 22 midway from the portion with the grommets G toward the connectors C2 and C3, and move toward the interior side of the inner panel 22 closer to the vehicle interior.

[0055] The section of wire 52 extending along the access cover 40 is positioned closer to the interior side of the vehicle than the access cover 40. Furthermore, the path of the section of wire 52 extending along the access cover 40 is restricted within the access cover 40. Restricting the path of wire 52 means that the path of wire 52 is maintained within a predetermined path.

[0056] The section of the wire 52 extending along the access cover 40A is accommodated in three slots 44A1, 44A2, and 44A3. Each slot 44A1, 44A2, and 44A3 is formed along the path of the wire 52 relative to the access cover 40A. Slot 44A1 is formed from the front of the access cover 40 towards the rear along the vehicle's longitudinal direction. When viewed from the passenger compartment side, slot 44A1 is formed as a straight line extending along the vehicle's longitudinal direction. Slots 44A2 and 44A3 branch from the ends of slot 44A1. Slot 44A2 is formed as a straight line extending along the vehicle's longitudinal direction. Slot 44A3 is formed as a straight line extending along the vehicle's height direction. Each slot 44 does not need to extend in a straight line on the main surface 41a of the cover body; it can also extend in a curved manner on the main surface 41a of the cover body.

[0057] The branching points of wires 52A and 52B on the access cover 40A split from a main line into two branch lines. The main line is the parallel section of wires 52A and 52B. The two branch lines are individual extensions of wires 52A and 52B. The main line is housed in slot 44A1, and the two branch lines are housed in slots 44A2 and 44A3, respectively. Slots 44A1 and 44A2 can be used to hold wires 52A connected to door devices installed towards the lower part of the door 10, such as footlights. Slots 44A1 and 44A3 can be used to hold wires 52B connected to door devices installed towards the rear of the door 10, such as door locking and unlocking actuators. The size of slot 44A1, which houses the main line, in the cross-sectional view can be made larger than the size of slots 44A2 and 44A3, which house the branch lines, in the cross-sectional view.

[0058] Wire 52B extends from access cover 40A toward access cover 40B. Wire 52B is housed in slot 44 within access cover 40B. Slots 44B1 and 44B2 are formed in access cover 40B. Furthermore, three slots 44B3, 44B4, and 44B5 are formed in access cover 40B, connecting slots 44B1 and 44B2 with different path lengths. Slot 44B3 connects slots 44B1 and 44B2 with the shortest distance. Slot 44B4 connects slots 44B1 and 44B2 with a path length longer than slot 44B3. Slot 44B5 connects slots 44B1 and 44B2 with a path length longer than slot 44B4. Slots 44B1 and 44B2 are the first and second positions on the cover body 41. Furthermore, slots 44B3, 44B4, and 44B5 are examples of path indicators that show multiple paths of different lengths as paths for the wire 52 between the first and second positions. The path indicator is formed to extend along multiple paths on the main surface 41a of the cover body 41, and includes multiple slots 44B3, 44B4, and 44B5 that accommodate the wiring member 50.

[0059] The path of wire 52B is restricted by passing through slots 44B1 and 44B2. The two ends of the section of wire 52B extending along the access cover 40B are respectively received in slots 44B1 and 44B2. Between slots 44B1 and 44B2, the path of wire 52B is restricted by passing through any one of multiple paths selected from among them. The middle portion of the section of wire 52B extending along the access cover 40B is received in any one of slots 44B3, 44B4, and 44B5. It is not necessary to provide three paths between slots 44B1 and 44B2; two or more paths may be provided. Furthermore, here, as a path between slots 44B1 and 44B2, relative to the shortest path (slot 44B3), two or more other circuitous paths (slots 44B4 and 44B5) are arranged on one side. As a path between slots 44B1 and 44B2, it is also possible to separate and arrange two or more other detour paths on both sides relative to the shortest path (slot 44B3).

[0060] Multiple wires 52 are housed freely within the slot 44. "Freely housed" means the multiple wires 52 are not bundled by any binding member. The multiple wires 52 are arranged individually within the slot 44. The sections of the multiple wires 52 that are positioned on the access cover 40 are housed within the slot 44 and covered by the wiring cover 60, thus becoming bundled. The multiple wires 52 can also be housed within the slot 44 while being bundled by a binding member.

[0061] A wiring cover 60 is fixed to an access panel cover 40. The wiring cover 60 closes the opening of the slot 44. The wiring cover 60 is configured, for example, in a plate-like shape, spanning the upper part of the slot 44. The first end 61 and the second end 62 of the wiring cover 60 protrude to both sides of the slot 44, respectively. The intermediate portion 63 of the wiring cover 60, which connects the first end 61 and the second end 62, covers the top of the slot 44. The first end 61 and the second end 62 are mounted to the main surface 41a of the access panel cover 40 by bonding or heat application, etc.

[0062] <Example of Specification Change>

[0063] Figure 3 This is a top view showing a first specification modification example of the door wiring module 30 according to Embodiment 1 and a door panel 20X equipped with the first specification modification example. Figure 4 This is a top view showing a second specification modification example of the door wiring module 30 of Embodiment 1 and a door panel 20Y equipped with the second specification modification example.

[0064] The door wiring module 30X in the first specification variation example and the door wiring module 30Y in the second specification variation example are manufactured using the same wire 52B and access cover 40B as the door wiring module 30. In the three door wiring modules 30, 30X, and 30Y, the path of the wire 52B in the access cover 40B is different. This difference in the path of the wire 52B is due to the difference in specifications of the three doors 10, 10X, and 10Y. As a simplified example of the difference in specifications of the aforementioned doors 10, 10X, and 10Y, we will explain this by taking the example that the length dimensions of the three door panels 20, 20X, and 20Y in the front-rear direction of the vehicle are different.

[0065] Compared to door panel 20, door panel 20X is longer in the longitudinal direction of the vehicle. Door panel 20Y is also longer in the longitudinal direction of the vehicle compared to door panels 20 and 20X. Therefore, the required length of wire 52B becomes the longest when installed in door panel 20Y. Therefore, the length of wire 52B is set to the length envisioned when installed in door panel 20Y. Furthermore, due to the commonality of wire 52B, wire 52B with a length corresponding to door panel 20Y is also suitable for door wiring modules 30 and 30X installed in door panels 20 and 20X. Consequently, in door wiring modules 30 and 30X, excess length of wire 52B is generated, which is absorbed at the access cover 40B. At this time, the path indicator shows three paths (including paths that do not require excess length absorption) that can appropriately absorb the excess length of wire 52B as paths corresponding to door panels 20, 20X, and 20Y. According to the manufactured door wiring module 30, 30X, 30Y, wire 52B is configured along one of the multiple paths indicated by the path indicator.

[0066] More specifically, in the door wiring module 30Y, the wire 52B is restricted to pass through the shortest path length of slot 44B3 among the three slots 44B3-44B5 connecting slots 44B1 and 44B2 in the access cover 40B. Furthermore, in the door wiring module 30X, the wire 52B is restricted to pass through the second shortest path length of slot 44B4 among the three slots 44B3-44B5 connecting slots 44B1 and 44B2 in the access cover 40B. Moreover, in the door wiring module 30, the wire 52B is restricted to pass through the longest path length of slot 44B5 among the three slots 44B3-44B5 connecting slots 44B1 and 44B2 in the access cover 40B.

[0067] Of course, the difference in door specifications caused by different paths of the wire 52B in the access cover 40B is not limited to this example. As long as it is within the range that can be handled by the shared components (wire 52B and access cover 40B), it can be arbitrary. For example, the difference in door specifications could be due to differences in the path of the part of the wire 52B that is closer to the connector C1 than the part whose path is restricted by the access cover 40B.

[0068] <Manufacturing Method>

[0069] Next, the manufacturing method of wiring modules 30, 30X, and 30Y for the car doors will be explained. Figure 5 This is a diagram illustrating the manufacturing method of the wiring module 30 for car doors.

[0070] The manufacturing method of the wiring modules 30, 30X, and 30Y for vehicle doors includes a preparation process and a path restriction process. The preparation process involves preparing an access cover 40, which includes a cover body 41 and a path indicator provided on the cover body 41. The path restriction process is a process of restricting the path of the wiring member 50 by passing through a first position and a second position on the cover body 41. Here, the path indicator in the access cover 40 indicates multiple paths of different lengths as the path between the first and second positions. In the path restriction process, the wiring member 50 is restricted to pass through any one of the multiple paths indicated by the path indicator as the path between the first and second positions.

[0071] Specifically, here, an access cover 40B with slots 44B1-44B5 is prepared. Slots 44B1 and 44B2 are formed at positions corresponding to a first position and a second position on the cover body 41. Wiring members 50 are restricted in their path by passing through slots 44B1 and 44B2. Slots 44B3-44B5 are provided as path indicators. Wiring members 50 are restricted in their path by passing through any one of slots 44B3-44B5 as a path between slots 44B1 and 44B2. For example, during manufacturing... Figure 1 In the case of the door wiring module 30 shown, the wiring member 50 is restricted in its path by passing through slot 44B5 as a path between slots 44B1 and 44B2. For example, in manufacturing... Figure 3 In the case of the door wiring module 30X shown, the wiring member 50 is restricted in its path by passing through slot 44B4 as a path between slots 44B1 and 44B2. For example, in manufacturing... Figure 4 In the case of the door wiring module 30Y shown, the wiring member 50 is restricted in its path by passing through the slot 44B3 as a path between slots 44B1 and 44B2. Through the above, door wiring modules 30, 30X, and 30Y are manufactured in which the wire 52B is arranged on the access cover 40B along an appropriate path according to its remaining length.

[0072] <Effects of Implementation Method 1, etc.>

[0073] According to the door wiring modules 30, 30X, and 30Y configured as described above, the path indicator shows multiple paths of different lengths as the paths for the wire 52B between the first and second positions. The wire 52B is restricted to pass through any one of the multiple paths selected. Therefore, for example, by using the longest 52B among the specifications of multiple doors 10, 10X, and 10Y, and setting its path as any one of the multiple paths selected, the specifications of multiple doors 10, 10X, and 10Y can be accommodated. Thus, the access cover 40B and 52B can be made into a common component.

[0074] Furthermore, the path indicator includes multiple slots 44B3-44B5, which are formed to extend along multiple paths on the main surface 41a of the cover body 41 to accommodate the wire 52B. Thus, the wire 52B can be easily arranged along a predetermined path by being housed in the predetermined slots of the multiple slots 44B3-44B5.

[0075] Furthermore, in the access cover 40B configured as described above, the path indicator shows multiple paths of different lengths as the paths between the first and second positions of the wire 52B, which is arranged to pass through the first and second positions on the cover body 41. Thus, for example, by using the longest wire 52B among the specifications of multiple doors 10, 10X, and 10Y, and setting its path to any path selected from the multiple paths, it is possible to accommodate the specifications of multiple doors 10, 10X, and 10Y. Therefore, the access cover 40B and the wire 52B can be made into a shared component.

[0076] Furthermore, according to the manufacturing method of the door wiring modules 30, 30X, and 30Y configured as described above, the path indicator shows multiple paths of different lengths as paths between the first and second positions. In the path limiting process, the wire 52B is path-limited by passing through any one of the multiple paths indicated by the path indicator as the path between the first and second positions. Thus, for example, by using the longest wire 52B among the specifications of multiple doors 10, 10X, and 10Y, and setting its path as any one of the multiple paths selected, the specifications of multiple doors 10, 10X, and 10Y can be accommodated. Therefore, the access cover 40B and the wire 52B can be made into a shared component.

[0077] [Variation Example]

[0078] Figure 6 This is a top view showing a first modified example of the wiring module 30 for the car door. Figure 7 This is a partially enlarged perspective view of the door wiring module 130 of the first modified example.

[0079] The door wiring module 130 in the first modification differs from the door wiring module 30 in that the path indicator provided on the access cover 140B is not a slot 44B3-44B5. In the door wiring module 130, the path indicator is provided as a fixing part 45. The fixing part 45 is formed on the main surface 41a of the cover body 41 at positions corresponding to multiple paths. The fixing part 45 is provided in a manner that allows the wiring member 50 to be fixed. Figure 7 An example is shown where a protrusion for attaching the wiring component 50 is provided as a fixing part 45. The fixing part 45 has a post 46a and a head 46b. The post 46a protrudes from the main surface 41a. The wiring component 50 is attached to the post 46a. The head 46b is located at the front end of the post 46a. The head 46b protrudes outward from the post 46a, preventing the wiring component 50 from falling off.

[0080] However, the fixing part does not necessarily have to be a protrusion. For example, the fixing part can be a clamping hole or the like. The clamping member installed on the wiring component 50 is fitted and fixed in the clamping hole, thereby fixing the wiring component 50 to the access cover.

[0081] It should be noted that, here, fixing parts 45 are provided in the paths where the excess length of wire 52B is absorbed, that is, in the paths corresponding to door panels 20 and 20X, respectively. Fixing parts 45 are not provided in the paths where the excess length of wire 52B does not need to be absorbed, that is, in the path corresponding to door panel 20Y. Fixing parts 45 can also be provided in the path corresponding to door panel 20Y.

[0082] In the door wiring module 30 of this example, the path indicator includes a fixing part 45. As a result, the wiring member 50 can be easily maintained in a state where the path is restricted in a predetermined path by fixing it to the fixed part 45.

[0083] Figure 8 This is a top view showing a second variation of the wiring module 30 for the car door.

[0084] The second variation of the door wiring module 230 differs from door wiring modules 30 and 130 in that the path indicator provided on the access cover 240B is neither a slot 44B3-44B5 nor a fixing part 45. In the door wiring module 230, the path indicator is a marker 47. The marker 47 is formed on the main surface 41a of the cover body 41 at positions corresponding to multiple paths. The marker 47 does not have the function of accommodating wiring components 50 like slots 44B3-44B5, nor the function of fixing wiring components 50 like the fixing part 45; it only functions as a mark. In this case, the wiring components 50 can be installed at the position of the marker 47 by means of a wiring cover 60 or an adhesive tape or other mounting component.

[0085] It should be noted that, here, markings 47 are provided on the paths where the excess length of the wire 52B is absorbed, that is, on the paths corresponding to door panels 20 and 20X, respectively. Markings 47 are not provided on the paths where the excess length of the wire 52B is not absorbed, that is, on the path corresponding to door panel 20Y. A fixing part 45 may also be provided on the path corresponding to door panel 20Y.

[0086] In the door wiring module 230 of this example, the path indicator includes a mark 47. Therefore, the wiring component 50 is arranged along the designated mark 47, thus facilitating its arrangement along the designated path.

[0087] Figure 9 This is a top view showing a third variation of the wiring module 30 for the car door.

[0088] The third variation of the door wiring module 330 differs from the door wiring module 30 in that it passes through different wiring components in two or more of the multiple paths indicated by the path indicator.

[0089] In addition to the aforementioned wiring component 50, the door wiring module 330 also includes a dedicated wiring component 54. The wires 52B in the wiring component 50 are restricted in their path by passing through a first path among multiple paths. The dedicated wiring component 54 is restricted in its path by passing through a second path among multiple paths.

[0090] The dedicated wiring component 54 is a wiring component specially designed according to the specifications of the door 10. Therefore, the second path taken by the dedicated wiring component 54 is usually the shortest path. The connector C6 at the end of the dedicated wiring component 54 is connected to the corresponding door device.

[0091] Wire 52B is a universal wiring component installed regardless of the specifications of doors 10, 10X, and 10Y. In the door wiring module 330, the first path through which wire 52B passes is longer than the second path. As described above, wire 52B is set to a length corresponding to the longest path length among the specifications of the multiple doors 10, 10X, and 10Y. Therefore, in the door wiring module 330 for doors 10 and 10X with a path length shorter than the longest path length among the specifications of the multiple doors 10, 10X, and 10Y, wire 52B passes through the path with a path length longer than the shortest path among the multiple paths, and the remaining length is absorbed. Figure 9 The door wiring module 330 shown is similar to the door wiring module 30, illustrating an example of a specification applicable to the door 10.

[0092] It should be noted that in the door wiring module of the specification of door 10Y, which is the longest path length among the specifications applicable to multiple doors 10, 10X, and 10Y, the wire 52B is restricted in the same way as the dedicated wiring component 54, by passing through the first path, which is the shortest path.

[0093] In this example, the door wiring module 330 also includes a dedicated wiring component 54. The wire 52B is restricted to a first path among multiple paths, and the dedicated wiring component 54 is restricted to a second path among multiple paths. For example, the wiring components that pass through the first and second positions sometimes include dedicated wiring components specifically designed for the specifications of multiple doors 10, 10X, and 10Y, and universal wiring components that are common to the specifications of multiple doors 10, 10X, and 10Y. In this case, the dedicated wiring component 54 and the wire 52B can be easily arranged on the access cover 40B along a predetermined path by changing the path of the wire 52B, which is a universal wiring component.

[0094] It should be noted that the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other. For example, the slots 44B3-44B5 and the fixing part 45 can also be provided as path indicator parts.
