[0003] PRIOR ART DOCUMENTS

[0004] Patent Document 1: Japanese Patent Application Publication No. 10-294146 SUMMARY

[0005] PROBLEMS TO BE SOLVED BY THE INVENTION

[0006] However, the tape winding work takes time and labor, and in addition, when the adhesive force of the tape is weakened due to deterioration over the years, there is a risk that the rubber cover will shift, and for the above reasons, it is desirable that the rubber cover can be installed even without performing the tape winding. Furthermore, when the rubber cover is installed after the connector housing is provided to the electric wire end portion, work of passing the connector housing through the rubber cover is required, so it is desirable to pass the electric wire through the rubber cover before the connector housing is provided to the electric wire end portion.

[0007] Therefore, an object is to provide a technology by which a cover member can be installed even without performing tape winding, and by which a connector housing can be provided to an electric wire end portion after passing the electric wire through the cover member.

[0008] TECHNICAL SOLUTION TO THE PROBLEM

[0009] The wiring member of the present disclosure includes a wire-like transmission member including an electric wire, a connector housing that houses an end portion of the electric wire along a length direction, an outer member that is provided to an intermediate portion of the electric wire along the length direction and is fixed to an outer peripheral portion of the wire-like transmission member, and a cover member that is provided between the connector housing and the outer member along the length direction of the electric wire and is fitted to the outer peripheral portion of the wire-like transmission member, the cover member and the wire-like transmission member being relatively movable along the length direction of the electric wire, and the connector housing and the outer member restricting movement of the cover member along the length direction of the electric wire, the cover member being an elastic member including an elastic cylinder portion that is compressively deformable in the length direction thereof.

[0017] [Explanation of Embodiments of the Present Disclosure]

[0018] First, an embodiment of the present disclosure will be explained.

[0019] The wiring member of the present disclosure is as described below.

[0020] (1) A wiring member, a wire-like transmission member including an electric wire; a connector housing that houses an end portion of the electric wire along a length direction; an outer member that is provided to an intermediate portion of the electric wire along the length direction and is fixed to an outer peripheral portion of the wire-like transmission member; and a cover member that is provided between the connector housing and the outer member along the length direction of the electric wire and is fitted to the outer peripheral portion of the wire-like transmission member, the cover member being relatively movable along the length direction of the electric wire with respect to the wire-like transmission member, and the connector housing and the outer member restricting movement of the cover member along the length direction of the electric wire, the cover member being an elastic member including an elastic cylinder portion that is compressively deformable in a length direction thereof. The cover member is relatively movable along the length direction of the electric wire with respect to the wire-like transmission member, and the connector housing and the outer member restrict movement of the cover member along the length direction of the electric wire, so that the cover member is maintained in a state of being mounted to a predetermined position even without performing a tape winding. In addition, the cover member is an elastic member including an elastic cylinder portion that is compressively deformable in a length direction thereof, so that processing of the end portion of the electric wire becomes easy by compressively deforming the elastic cylinder portion even after the cover member is fitted to the electric wire.

[0021] (2) In the wiring member of (1), it can also be that, when the cover member is intended to move toward the connector housing side along the length direction of the electric wire, the first contact portion provided to one end portion of the cover member contacts the connector housing side contact portion of the connector housing to restrict the movement thereof, and when the cover member is intended to move toward the outer fitting member side along the length direction of the electric wire, the second contact portion provided to the other end portion of the cover member contacts the outer fitting member side contact portion of the outer fitting member to restrict the movement thereof, the natural length of the cover member from the first contact portion to the second contact portion is the same as or longer than the length from the connector housing side contact portion to the outer fitting member side contact portion. Thus, the cover member hardly moves along the length direction of the electric wire.

[0022] (3) In the wiring member of (2), it can also be that the natural length of the cover member from the first contact portion to the second contact portion is longer than the length from the connector housing side contact portion to the outer fitting member side contact portion. Thus, both end portions of the cover member become a state of being pressed by the connector housing and the outer fitting member, and the cover member is less likely to come off.

[0023] (4) In any one of the wiring members of (1) to (3), it can also be that the elastic barrel portion is formed in a corrugated shape in which a large diameter portion and a small diameter portion are alternately and continuously arranged along the length direction, and a diameter expanding portion in which the diameter gradually increases from one side of the small diameter portion toward the other side of the large diameter portion is provided between the small diameter portion and the large diameter portion in the elastic barrel portion, and in a state in which the elastic barrel portion is compressed and deformed, the inclination of the diameter expanding portion increases and the adjacent large diameter portions approach each other. Thus, the elastic barrel portion is easily compressed and deformed in shape.

[0024] (5) In any one of the wiring members of (1) to (4), it can also be that the cover member further includes a holding barrel portion which is more difficult to be compressed and deformed than the elastic barrel portion, and the holding barrel portion is provided at a position adjacent to the elastic barrel portion on the side of the outer fitting member. Thus, the cover member and the outer fitting member easily contact in a proper posture.

[0025] (6) In the wiring member of (5), it can also be that the length of the elastic barrel portion is longer than the length of the holding barrel portion when the cover member is in a natural length. Thus, the length in which the elastic barrel portion can be compressed and deformed can be made longer.

[0026] (7) In the wiring member of (5) or (6), the cover member can further include a ring-shaped protrusion protruding from the inner surface of the holding cylinder toward the wire-like transmission member, and the ring-shaped protrusion can be in contact with the outer peripheral portion of the wire-like transmission member. Thus, water or the like is prevented from being infiltrated between the holding cylinder and the wire-like transmission member.

[0027] (8) In the wiring member of (7), the wire-like transmission member can include a plurality of the electric wires, and at the position of the ring-shaped protrusion, the plurality of the electric wires can be covered by a protective portion, the outer surface of the protective portion can be ring-shaped, and the ring-shaped protrusion can be in contact with the outer surface of the protective portion. Thus, a gap is less likely to be generated between the ring-shaped protrusion and the protective portion having the ring-shaped outer surface.

[0028] (9) In any one of the wiring members of (1) to (8), the wire-like transmission member can include a plurality of the electric wires and a sheath covering the plurality of the electric wires, the portion of the plurality of the electric wires including the end portion accommodated in the connector housing can extend from the end portion of the sheath, and the end portion of the sheath can be located inside the cover member. Thus, the cover member covers the portion of the plurality of the electric wires not covered by the sheath. In addition, the end portion of the cover member on the outer packaging member side is located at the portion having the sheath.

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

[0030] Hereinafter, a specific example of the wiring member of the present disclosure will be described with reference to the drawings. Furthermore, the present disclosure is not limited to these examples, but is intended to include all modifications within the meaning and range equivalent to the claims by the claims.

[0031] [Embodiment 1]

[0032] Hereinafter, the wiring member 10 related to Embodiment 1 will be described. Figure 1 is a side view illustrating the wiring member 10 related to Embodiment 1. Figure 2 is an enlarged view of the region A1 in Figure 1 In Figure 2 , a portion of the outer packaging member 40 and a portion of the cover member 50 are shown in a cross-sectional view.

[0033] The wiring member 10 connects devices in a vehicle and transmits electricity or light. The wiring member 10 can be disposed at any position in the vehicle. Here, the wiring member 10 is described as a wiring member 10 for a running system that connects devices on the vehicle body side and devices of the running system in the vehicle. In Figure 1 , a portion of the wiring member 10 including the end portion on the side of the devices connected to the running system is shown. The wiring member 10 includes a wire-like transmission member 20, a connector housing 30, an outer packaging member 40, and a cover member 50.

[0034] <Linear transmission components>

[0035] The linear transmission component 20 is a linear component that transmits electricity or light. Here, the linear transmission component 20 includes a wire 22. The wire 22 includes a core wire 23 and a sheath 24 (see reference). Figure 4 The core wire 23 is a linear component formed from metal wires such as copper, copper alloy, aluminum, or aluminum alloy. The core wire 23 can be a single wire or a stranded wire composed of multiple wires twisted together. The sheath 24 is an insulating portion covering the periphery of the core wire 23. The sheath 24 is formed, for example, by extruding resin around the core wire 23. The linear transmission component may also include optical fibers for transmitting optical signals.

[0036] The linear transmission component 20 may contain only a single wire 22 or multiple wires 22. Here, the linear transmission component 20 contains multiple (in this case, four) wires 22. The linear transmission component 20 also includes a sheath 26 covering the multiple wires 22. The sheath 26 is formed of resin or the like. The sheath 26 is formed, for example, by extruding resin around the multiple wires 22.

[0037] The wire 22 can be either a signal wire or a power wire. For example, if the wiring component 10 is a wiring component for a running system, the wire 22 can also be a power wire supplying power to an EPB (Electric Parking Brake) or an EMB (Electro-Mechanical Brake). For example, if the wiring component 10 is a wiring component for a running system, the wire 22 can also be a signal wire transmitting signals from sensors used to detect wheel speed in an ABS (Anti-Lock Brake System). The wiring component 10 can also be used as a composite wiring harness containing multiple types of wires 22. As described above, if the wiring component 10 contains wires 22 as power lines and wires 22 as signal lines, the wiring component 10 is a composite wiring harness. In particular, if the wiring component 10 contains a power line for an electric brake and a signal line for vehicle speed detection, the wiring component 10 is a composite wiring harness for brakes.

[0038] Two of the four electric wires 22, 22A are power supply lines for the EPB. The other two of the four electric wires 22, 22B are signal lines for the ABS sensor. The number of the electric wires 22 in the wire-like transmission member 20 is not limited to this, and can be any number. For example, the wire-like transmission member 20 can include six electric wires. Four of the six electric wires are provided as the power supply lines for the EPB, the signal lines for the ABS sensor, and the remaining two electric wires can be either power supply lines for other devices in the running system of the vehicle such as the EMB or signal lines for other sensors in the running system of the vehicle or for control of other devices.

[0039] The one end portions of the plurality of electric wires 22 are all housed in the same connector housing 30. The portions of the plurality of electric wires 22 including the one end portions housed in the connector housing 30 extend from one end portion of the sheath 26. The one end portion of the sheath 26 is separated from the connector housing 30 in the length direction of the wire-like transmission member 20.

[0040] <Connector Housing>

[0041] The one end portions of the electric wires 22 along the length direction are housed in the connector housing 30. The outer shape of the connector housing 30 is formed, for example, in a rectangular parallelepiped shape. A cavity is formed in the connector housing 30. The cavity penetrates the connector housing 30. One side opening portion of the cavity is formed in the rear end face 31 of the connector housing 30. The rear end face 31 is formed, for example, in a rectangular shape or a square shape, or the like. The one end portions of the electric wires 22 are inserted into the inside of the cavity from the one side opening portion of the cavity. A terminal T (refer to FIG. 2) is provided, for example, at the one end portion of the electric wire 22. The terminal T and the portion of the electric wire 22 connected to the terminal T are housed in the cavity. The portion of the electric wire 22 further from the portion connected to the terminal T toward the other end side extends to the outside of the cavity. The terminal T can be either a male terminal or a female terminal. Figure 4 ). The terminal T and the portion of the electric wire 22 connected to the terminal T are housed in the cavity. The portion of the electric wire 22 further from the portion connected to the terminal T toward the other end side extends to the outside of the cavity. The terminal T can be either a male terminal or a female terminal.

[0042] <Outer Cover Member>

[0043] The outer member 40 is provided to the middle portion of the electric wire 22 in the longitudinal direction. The outer member 40 is fixed to the outer peripheral portion of the wire-like transmission member 20. The outer member 40 can be provided for any purpose. Here, the outer member 40 is a fixing member mounting portion 40. The fixing member mounting portion 40 is a portion that intervenes between the wire-like transmission member 20 and the fixing member B when the fixing member B is fixed to the wire-like transmission member 20 and becomes a base. Here, the fixing member mounting portion 40 includes a main body portion 41 and a rib 42. The main body portion 41 and the rib 42 are provided, for example, in a ring shape. The rib 42 projects outward in the peripheral direction compared to the main body portion 41. The fixing member B is provided to the outer peripheral portion of the main body portion 41. The rib 42 is provided to positions on both sides of the main body portion 41 in the longitudinal direction of the wire-like transmission member 20. The rib 42 suppresses positional displacement of the fixing member B in the longitudinal direction of the wire-like transmission member 20 or detachment from the main body portion 41.

[0044] However, the outer member 40 need not be the fixing member mounting portion 40. For example, the outer member 40 can also be the fixing member B itself. That is, the fixing member mounting portion 40 can be omitted from the wiring member 10, and the fixing member B can be directly fixed to the outer surface of the wire-like transmission member 20. In addition, for example, the outer member can also be a branch maintaining portion. The branch maintaining portion is provided to the branch portions of the plurality of electric wires 22 and maintains the branch shape.

[0045] The outer member 40 can also be provided to the outer peripheral portion of the electric wire 22 in any manner. For example, the outer member 40 can also be a resin molded portion. In addition, for example, the outer member 40 can also be a separate molded member that is molded independently of the wire-like transmission member 20. In the case where the outer member 40 is a separate molded member, the outer member 40 can also be a protection member or the like.

[0046] The resin molded portion is embedded molded with the wire-like transmission member 20 as an embedded member. In the case where the outer member 40 is a resin molded portion, the longitudinal direction middle portion of the wire-like transmission member 20 is buried inside the resin molded portion, and the outer member 40 is fixed to the wire-like transmission member 20. In the case where the outer member 40 is a resin molded portion, it is preferable that the resin of the resin molded portion directly engages with the resin of the outer peripheral portion of the wire-like transmission member 20.

[0047] In the case where the outer member 40 is a separate molded member, the material of the outer member 40 is appropriately set in accordance with the purpose of the outer member 40. For example, in the case where the outer member 40 is the fixing member mounting portion 40 or the branch maintaining portion, the outer member 40 can also be a molded member composed of resin or rubber or the like. For example, in the case where the outer member 40 is the fixing member B, the outer member 40 can also be a molded member composed of metal or resin or the like.

[0048] In the case where the outer member 40 is a separate shaped member, a fixing portion that fixes the outer member 40 to the outer peripheral portion of the wire-like transmission member 20 can be provided in the wiring member 10. The fixing portion can be any structure, for example, an adhesive, a tape, or the like.

[0049] Here, the fixing member B is a member for fixing the wiring member 10 to the vehicle. The fixing member B is, for example, a bracket B. The bracket B is formed in a plate shape from resin or metal. A through-hole BH is formed in the bracket B. The bracket B is fixed to the vehicle by fastening a bolt that passes through the through-hole BH to an attaching portion on the vehicle side. The bracket B can also be fixed to the fixing member mounting portion 40 by riveting. The bracket B can also be provided as an insert member when the fixing member mounting portion 40 is insert-molded with the wire-like transmission member 20 as an insert member. In this case, a portion of the bracket B is embedded in the fixing member mounting portion 40.

[0050] The end face 61 of the other end side of the cover member 50 is in contact with the front end face 43 of the connector housing 30 side in the outer member 40. The front end face 43 is provided as a flat face. In addition, the inner edge of the front end face 43 is circular in shape, and the diameter (inner diameter of the outer member 40 at the front end face 43) is the same as the outer diameter of the wire-like transmission member 20 (here, the outer diameter of the sheath 26). In addition, the outer edge of the front end face 43 is circular in shape, and the diameter (outer diameter of the outer member 40 at the front end face 43) is larger than the outer diameter of the cover member 50. The outer diameter of the outer member 40 at the front end face 43 is larger than the sum of the gap between the cover member 50 and the wire-like transmission member 20 (the difference between the inner diameter of the cover member 50 and the outer diameter of the wire-like transmission member 20) and the outer diameter of the end face 61 of the cover member 50.

[0051] < Cover Member >

[0052] The cover member 50 is provided between the connector housing 30 and the outer member 40 along the length direction of the electric wire 22. The cover member 50 is fitted to the outer peripheral portion of the wire-like transmission member 20. The cover member 50 and the wire-like transmission member 20 are relatively movable along the length direction. The cover member 50 is not fixed to the wire-like transmission member 20 by a tape or the like. The connector housing 30 and the outer member 40 restrict the movement of the cover member 50 along the length direction of the wire-like transmission member 20. Thus, in the wiring member 10, the cover member 50 is positioned at a predetermined position. The cover member 50 is an elastic member formed of an elastic body such as rubber. The cover member 50 includes an elastic cylinder portion 51. Here, the cover member 50 also includes a holding cylinder portion 55, a ring-shaped convex portion 57, and a connector cover portion 58.

[0053] The elastic tube portion 51 is able to be compressed and deformed in the length direction thereof. Hereinafter, the state in which the elastic tube portion 51 is at the natural length will be simply referred to as the natural length. The elastic tube portion 51 is formed in a corrugated shape in which the large diameter portion 52 and the small diameter portion 53 are alternately and continuously arranged in the length direction. The large diameter portion 52 is a portion in which the diameter is the largest in the elastic tube portion 51. The small diameter portion 53 is a portion in which the diameter is the smallest in the elastic tube portion 51. In the elastic tube portion 51, the expansion portion 54 is provided between the small diameter portion 53 and the large diameter portion 52. The expansion portion 54 is a portion in which the diameter gradually increases as it proceeds from the side of the small diameter portion 53 toward the side of the large diameter portion 52. In the elastic tube portion 51, the wall thickness of the large diameter portion 52, the small diameter portion 53, and the expansion portion 54 is the same degree. In the state in which the elastic tube portion 51 is compressed and deformed, the inclination of the expansion portion 54 is larger than that in the natural length, and the adjacent large diameter portions approach each other.

[0054] Here, in the natural length, the expansion portion 54 is continued in the length direction as a whole between the large diameter portion 52 and the small diameter portion 53. That is, there is no portion in which the diameter is continuous in the middle between the large diameter portion 52 and the small diameter portion 53. Here, in the expansion portion 54, the diameter increases in a linear function as it proceeds from the side of the small diameter portion 53 toward the side of the large diameter portion 52. For example, the slope (the slope with respect to the axial direction) of the expansion portion 54 can be less than 45 degrees in the natural length and can be more than 45 degrees in the compressed and deformed state. In addition, here, in the natural length, the expansion portion 54 is longer than the large diameter portion 52 and the small diameter portion 53. The large diameter portion 52 is hardly continuous in the length direction with the same diameter. Similarly, the small diameter portion 53 is hardly continuous in the length direction with the same diameter.

[0055] The length dimension and the amount of compression and deformation of the elastic tube portion 51 are set to a length dimension in which the one end portion of the electric wire 22 can be extended by a predetermined amount from the one end portion of the cover member 50 in the state in which the other end portion of the cover member 50 is in contact with the outer cover member 40 and the elastic tube portion 51 is compressed and deformed. The above-mentioned predetermined amount of extension of the electric wire 22 can be appropriately set according to the processing performed on the one end portion of the electric wire 22 after the cover member 50 is assembled. In the case where the processing performed on the one end portion of the electric wire 22 after the cover member 50 is assembled includes the press welding of the terminal T to the electric wire 22 and the insertion of the terminal T into the connector housing 30, for example, the above-mentioned predetermined amount of extension of the electric wire 22 can be set to about 40 mm to 60 mm. At this time, in the case where the other end portion of the cover member 50 at the natural length is in contact with the outer cover member 40 and the front end of the electric wire 22 is located at the same position as the front end of the cover member 50, the elastic tube portion 51 needs to be able to be compressed and deformed by at least about 40 mm to 60 mm.

[0056] The holding cylinder portion 55 is a portion that is less compressively deformed than the elastic cylinder portion 51. The holding cylinder portion 55 is provided at a position adjacent to the elastic cylinder portion 51 on the side of the outer member 40. The base end portion of the elastic cylinder portion 51 side in the holding cylinder portion 55 is continuous at the same diameter. The outer diameter and the inner diameter at the base end portion of the holding cylinder portion 55 are the same degree as the diameter of the small diameter portion 53. A rib 56 is formed on the outer surface of the front end portion of the holding cylinder portion 55. The rib 56 is annularly raised on the outer peripheral side of the holding cylinder portion 55. Thus, the outer diameter of the front end portion of the holding cylinder portion 55 is made large. The inner diameter of the front end portion of the holding cylinder portion 55 is the same as the inner diameter of the base end portion of the holding cylinder portion 55. Thus, the front end portion of the holding cylinder portion 55 is made thicker-walled than the base end portion of the holding cylinder portion 55, and the rigidity is increased. Here, the outer diameter of the rib 56 is the same as or smaller than the outer diameter of the rib 42. Thus, the rear end surface 61 of the holding cylinder portion 55 can be in contact with the front end surface 43 of the outer member 40 in its entirety.

[0057] The length dimension of the holding cylinder portion 55 can be any length dimension. Here, when the cover member 50 is a natural length, the length dimension (dimension D1 in Figure 3 ) of the elastic cylinder portion 51 is longer than the length dimension (dimension D2 in Figure 3 ) of the holding cylinder portion 55. Thus, the compressive deformation amount of the elastic cylinder portion 51 can be increased. For example, the holding cylinder portion 55 is longer than the interval of two large diameter portions 52 continuous in the length direction in the natural length. Also, for example, the holding cylinder portion 55 is shorter than the interval of the outer two of three large diameter portions 52 continuous in the length direction in the natural length. Also, for example, the length of the elastic cylinder portion 51 is longer than the length of the holding cylinder portion 55 in a state where the operator has maximally compressed the elastic cylinder portion 51 within the compressible range.

[0058] The annular convex portion 57 protrudes from the inner surface of the holding cylinder portion 55 toward the wire-shaped transport member 20. The annular convex portion 57 is provided at an intermediate portion of the holding cylinder portion 55 along the axial direction. The annular convex portion 57 is provided with a plurality of (two in this case) at intervals from each other along the axial direction of the holding cylinder portion 55. The annular convex portion 57 can be provided with only one. The annular convex portion 57 is in contact with the outer peripheral portion of the wire-shaped transport member 20. The annular convex portion 57 is in contact with the wire-shaped transport member 20 in its entirety along the circumferential direction. The inner surface of the annular convex portion 57 is annular (circular in this case) in cross section.

[0059] At the position of the annular protrusion 57, the plurality of electric wires 22 is covered by the protection portion 26 whose outer surface is annular (here, circular shape). Thereby, the outer surface of the protection portion 26 is gentle compared to the portion of the plurality of electric wires 22 which is exposed, and a gap is less likely to occur between the protection portion 26 and the annular protrusion 57. Here, the sheath 26 functions as the protection portion 26. However, the protection portion 26 is not limited to the sheath 26. For example, it can be that a portion of the fixed member mounting portion 40 is extended to the connector housing 30 side, and the extended portion is provided as the protection portion 26.

[0060] The outer diameter of the protection portion 26 is made smaller than the inner diameter of the holding cylinder portion 55. Therefore, the outer surface of the protection portion 26 and the inner surface of the holding cylinder portion 55 face each other with a gap at least in a part along the circumferential direction. The annular protrusion 57 is in contact with the outer surface of the protection portion 26. The inner surface of the annular protrusion 57 is in contact with the outer surface of the protection portion 26 as a whole along the circumferential direction. The inner diameter of the annular protrusion 57 is the same as or smaller than the outer diameter of the protection portion 26. In the case where the inner diameter of the annular protrusion 57 is smaller than the outer diameter of the protection portion 26, the annular protrusion 57 is provided in a state of being elastically deformed in a manner of expanding to the outer circumferential side by the protection portion 26. Thereby, a gap is less likely to occur between the annular protrusion 57 and the protection portion 26.

[0061] The connector cover portion 58 is provided at a position next to the connector housing 30 side with respect to the elastic cylinder portion 51. The connector cover portion 58 covers the portion of the connector housing 30 including the rear end portion. Here, the connector cover portion 58 covers from the rear end portion to the intermediate portion of the connector housing 30. The connector cover portion 58 can also cover from the rear end portion to the front end portion of the connector housing 30. The connector cover portion 58 is formed in, for example, a square tube shape corresponding to the outer shape of the connector housing 30. A through hole is formed at a base end portion 59 in the connector cover portion 58 on the side of the elastic cylinder portion 51. Thereby, the connector cover portion 58 communicates with the elastic cylinder portion 51. The through hole is formed to be smaller than the rear end surface 31 of the connector housing 30. For example, the portion of the elastic cylinder portion 51 or the vicinity thereof in which the small diameter portion 53 is present is connected to the connector cover portion 58. The diameter of the through hole is set to be the same degree of diameter as the inner diameter of the portion of the elastic cylinder portion 51 or the vicinity thereof in which the small diameter portion 53 is present.

[0062] A first contact portion 60 (refer to FIG. 2) is provided at one end portion of the cover member 50. The first contact portion 60 is in contact with the second contact portion 61 of the fixed member 20. The first contact portion 60 is provided at the base end portion 59 of the connector cover portion 58. The first contact portion 60 is provided at the position of the through hole of the connector cover portion 58. The first contact portion 60 is provided at the position of the through hole of the connector cover portion 58. The first contact portion 60 is provided at the position of the through hole of the connector cover portion 58. Figure 3A connector housing-side contact portion 31 is provided on the connector housing 30. When the cover member 50 wants to move towards the connector housing 30 along the length direction of the wire 22, the first contact portion 60 contacts the connector housing-side contact portion 31 to restrict its movement. Here, the first contact portion 60 is the surface of the base end portion 59 of the connector cover portion 58 facing the front end portion of the connector housing 30. The first contact portion 60 is the periphery of the through hole formed in the base end portion 59 of the connector cover portion 58 and is located inside the connector cover portion 58. In addition, the connector housing-side contact portion 31 is the rear end face 31 of the connector housing 30.

[0063] A second contact portion 61 is provided at the other end of the cover member 50. An outer member side contact portion 43 is provided on the outer member 40. When the cover member 50 wants to move towards the outer member 40 along the length direction of the wire 22, the second contact portion 61 contacts the outer member side contact portion 43 to restrict its movement. Here, the second contact portion 61 is the rear end face 61 of the retaining tube portion 55, which faces the outer member 40. In addition, the outer member side contact portion 43 is the front end face 43 of the outer member 40, which faces the cover member 50.

[0064] An elastic cylinder portion 51 is disposed between the first contact portion 60 and the second contact portion 61. The cover member 50 is compressible and deformable between the first contact portion 60 and the second contact portion 61. Due to the compression deformation of the elastic cylinder portion 51, the length from the first contact portion 60 to the second contact portion 61 becomes shorter. In the cover member 50, the length from the first contact portion 60 to the second contact portion 61 is variable. The natural length of the cover member 50 from the first contact portion 60 to the second contact portion 61 (…) Figure 3 The dimension D3) and the length from the connector housing side contact 31 to the outer component side contact 43 ( Figure 5 The dimension D4 in the cover is the same as or longer than that. Here, the natural length of the cover from the first contact portion 60 to the second contact portion 61 is the same as the length from the connector housing side contact portion 31 to the outer component side contact portion 43, except for the case where they are exactly the same length, and also includes the case where they are slightly shorter. That is to say, in addition to the case where the group of the first contact portion 60 and the connector housing side contact portion 31 in the cover component 50 is in contact with the group of the second contact portion 61 and the outer component side contact portion 43, it also includes the case where one group is in contact while the other group is not in contact and is in a slightly separated position.

[0065] Here, the natural length of the cover member 50 from the first contact portion 60 to the second contact portion 61 is ( Figure 3 The dimension D3 is greater than the length from the connector housing side contact 31 to the outer component side contact 43. Figure 5the size D4) is long. Thus, the elastic cylinder portion 51 is compressed and deformed, and the second contact portion 61 comes into contact with the outer member side contact portion 43 while the first contact portion 60 is in contact with the connector housing side contact portion 31, and the elastic cylinder portion 51 is restricted from recovering. At this time, the force to be recovered acts on the connector housing side contact portion 31 and the outer member side contact portion 43 from the cover member 50, and the reaction force thereof acts on the cover member 50.

[0066] The end portion of the sheath 26 is located inside the cover member 50. When the cover member 50 is in the natural length, the end portion of the sheath 26 can be located inside the cover member 50, or can be located at any position inside the cover member 50. For example, when the cover member 50 is in the natural length, the end portion of the sheath 26 can also be located inside the elastic cylinder portion 51. In this case, as shown in Fig. 6, when the cover member 50 is compressed and deformed so that the second contact portion 61 in the cover member 50 comes into contact with the outer member side contact portion 43, the end portion of the sheath 26 can be located inside the elastic cylinder portion 51 as it is, or can be located inside the connector cover portion 58, or the end portion of the sheath 26 can extend from the end portion of the cover member 50. It is preferable that, when the cover member 50 is in the natural length, the end portion of the sheath 26 is preferably located at a position closer to the connector housing 30 side than the annular protrusion 57. Thus, the annular protrusion 57 can come into contact with the sheath 26. Figure 4

[0067] <Manufacturing Method>

[0068] An example of a manufacturing method of the wiring member 10 will be described with reference to Figs. 9A to 9D. Figures 3 to 5 Figures 3 to 5 Fig. 9A is a view showing a state in which the cover member 50 is inserted into the sheath 26.

[0069] First, the wire-like transmission member 20 is passed through the cover member 50. At this time, as shown in Fig. 9B, the front end portion of the wire-like transmission member 20, to which the outer member 40 is fixed in advance, is passed through the cover member 50. At this time, when the cover member 50 is inserted, the second contact portion 61 of the cover member 50 soon collides with the outer member side contact portion 43 of the outer member 40, and thus it is possible to inhibit the cover member 50 from being excessively inserted. Further, in the example shown in Fig. 9B, the wire-like transmission member 20 is passed through the cover member 50 in a state in which the front end portion of the sheath 26 is peeled off, but the front end portion of the sheath 26 can be peeled off after the wire-like transmission member 20 is passed through the cover member 50. Figure 3 Figure 3

[0070] ​​​​Next, the end portion of the electric wire 22 is processed. At this time, as shown in Figure 4 , the cover member 50 is compressed and deformed, and the end portion of the electric wire 22 extends from the cover member 50 by a predetermined length. The cover member 50 is maintained in the state of being compressed and deformed, and the end portion of the electric wire 22 extending from the cover member 50 is processed. As the processing of the end portion of the electric wire 22, the fitting of the terminal T and the insertion of the terminal T are conceivable. The fitting of the terminal T is to provide the terminal T to the end portion of the electric wire 22. For example, the terminal T can be press-welded to the end portion of the electric wire 22, or can be press-bonded or welded to the end portion of the electric wire 22. In the case of press-welding the terminal T, it is preferable to press-weld the terminal T after peeling the covering portion 24 at the end portion of the electric wire 22. The insertion of the terminal T is to insert the terminal T connected to the end portion of the electric wire 22 into the cavity of the connector housing 30.

[0071] When the terminals T of all the electric wires 22 are inserted into the cavity of the connector housing 30, the state of Figure 5 is obtained. Then, the compression and deformation of the cover member 50 is released, and the elastic cylinder portion 51 is elastically restored to be elongated. Thus, the connector cover 58 covers the rear end portion of the connector housing 30, and the wiring member 10 shown in Figure 1 is formed. At this time, the first contact portion 60 of the cover member 50 is in contact with the connector housing side contact portion 31.

[0072] Effects of Embodiment 1 and the Like

[0073] According to the wiring member 10 configured as described above, the cover member 50 and the wire-like transmission member 20 are relatively movable along the length direction of the electric wire 22, and the connector housing 30 and the outer cover member 40 restrict the movement of the cover member 50 along the length direction of the electric wire 22, so that the state of the cover member 50 being mounted to the predetermined position can be maintained even without performing the tape winding. In addition, the cover member 50 is an elastic member including the elastic cylinder portion 51 that is compressively deformable in the length direction, so that the processing of the end portion of the electric wire 22 becomes easy even after the cover member 50 is fitted to the electric wire 22 by being compressively deformed by the elastic cylinder portion 51.

[0074] In addition, the natural length of the cover member 50 from the first contact portion 60 to the second contact portion 61 (the dimension D3 in Figure 3 is the same as or longer than the length from the connector housing side contact portion 31 to the outer cover member side contact portion 43 (the dimension D4 in Figure 5 ). Thus, the cover member 50 hardly moves along the length direction of the electric wire 22. In particular, the natural length of the cover member 50 from the first contact portion 60 to the second contact portion 61 (the dimension D3 in Figure 3 is longer than the length from the connector housing side contact portion 31 to the outer cover member side contact portion 43 (the dimension D4 in Figure 5The dimension D4) is longer than the dimension D1) in the state where the elastic cylinder portion 51 is not compressed. Thus, the both end portions of the cover member 50 become a state of being pressed by the connector housing 30 and the outer member 40, and the cover member 50 is not easily loosened.

[0075] Further, in the state where the elastic cylinder portion 51 is compressed, the inclination of the diameter-enlarged portion 54 is large, and the adjacent large diameter portions 52 approach each other. Thus, the elastic cylinder portion 51 is easily compressed in shape.

[0076] Further, the holding cylinder portion 55 is provided at a position adjacent to the elastic cylinder portion 51 on the side of the outer member 40. Thus, the cover member 50 and the outer member 40 easily come into contact in a proper posture.

[0077] Further, in the state where the cover member 50 is in the natural length, the length (the dimension D1) of the elastic cylinder portion 51 is longer than the length (the dimension D2) of the holding cylinder portion 55. Thus, it is possible to make the length of the elastic cylinder portion 51 in which compression is possible longer. Figure 3 Figure 3 Further, the annular convex portion 57 comes into contact with the outer peripheral portion of the wire-like transmission member 20. Thus, it is possible to suppress water or the like from being infiltrated between the holding cylinder portion 55 and the wire-like transmission member 20. Further, the annular convex portion 57 comes into contact with the outer surface of the protection portion 26. Thus, it is not easy to generate a gap between the annular convex portion 57 and the protection portion 26 in which the outer surface is annular.

[0078] Further, the end portion of the sheath 26 is positioned inside the cover member 50. Thus, the portion of the plurality of electric wires 22 which is not covered by the sheath 26 is covered by the cover member 50. Further, the end portion of the cover member 50 on the side of the outer member 40 is positioned at the portion where the sheath 26 is present.

[0079] Further, the end portion of the sheath 26 is positioned inside the cover member 50. Thus, the portion of the plurality of electric wires 22 which is not covered by the sheath 26 is covered by the cover member 50. Further, the end portion of the cover member 50 on the side of the outer member 40 is positioned at the portion where the sheath 26 is present.

[0080] [Modified Example]

[0081] Hitherto, the structure in which the cover member 50 includes the holding cylinder portion 55 has been described, but this is not a necessary structure. For example, the holding cylinder portion 55 can be omitted from the cover member 50, and the elastic cylinder portion 51 can extend to the other end portion of the cover member 50.

[0082] Further, hitherto, the structure in which the cover member 50 includes the annular convex portion 57 has been described, but this is not a necessary structure. For example, the cover member 50 can not include the annular convex portion 57. In this case, a gap can be generated between the holding cylinder portion 55 and the wire-like transmission member 20. Further, the holding cylinder portion 55 itself can come into contact with the wire-like transmission member 20 on the entire circumference.

[0083] Further, hitherto, the structure in which the annular convex portion 57 comes into contact with the protection portion 26 has been described, but this is not a necessary structure. For example, the annular convex portion 57 can come into contact with the plurality of electric wires 22. ​

[0084] Further, while the structure in which the wire-like transmission member 20 includes the sheath 26 that covers the plurality of electric wires 22 has been described so far, this is not a necessary structure. The wire-like transmission member 20 can also not include the sheath 26. In this case, the plurality of electric wires 22 can be gathered by a tape or the like, or the plurality of electric wires 22 can not be gathered. Further, even in the case where the wire-like transmission member 20 includes the sheath 26 that covers the plurality of electric wires 22, it is not a necessary structure for the end portion of the sheath 26 to be located inside the cover member 50. For example, the end portion of the sheath 26 can also be located inside the branch maintaining portion that is the outer member.

[0085] Further, the structures described in each of the embodiments and each of the modified examples described above can be appropriately combined as long as they do not contradict each other.
