DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0011] [First embodiment] The wire harness WH shown in Figure 1 is, for example, a component in which multiple wiring materials W used for power supply and signal communication are bundled together to connect various devices installed in a vehicle, and the multiple wiring materials W are connected to each device using connectors or the like.

[0012] The wire harness WH includes a plurality of wiring materials W, a protector 1, and a caterpillar-shaped exterior material C assembled to the protector 1. The wire harness WH may further include a grommet, a fixing device, a connector, and the like.

[0013] The wiring material W is, for example, an insulated electric wire in which a core wire made of a bundle of conductive metal wires is covered with an insulating covering portion. The wiring material W may be a bundle of insulated electric wires. The wiring material W may also be an insulated metal rod in which a conductive metal rod is covered with an insulating covering portion.

[0014] The exterior material C is made of insulating resin material or the like, and is long when multiple pieces are connected together, and is attached to the end of the protector 1 as shown in Fig. 1, and the wiring material W is inserted into it to protect the wiring material W. The wiring material W is connected to movable parts such as a sliding door, a sliding seat, and a sunroof, and its extending direction changes according to the movement of the movable parts. The caterpillar-shaped exterior material C is used as a member that can guide the wiring material W from the protector 1 to the movable parts while holding the wiring material W in a straight or bent state.

[0015] The protector 1 is formed of an insulating resin material or the like, and protects the wiring material W by storing the wiring material W. The protector 1 is fixed to a vehicle and used as a member that regulates the wiring path of the wiring material W. As shown in FIG. 1, the protector 1 includes a base member 10 having a storage space portion 10S through which the wiring material W is inserted, and a cover member 20 that is assembled to the base member 10.

[0016] The protector 1 of this embodiment is structured to hold and store the wiring material W in an appropriate position by providing a positioning portion 200 in the cover member 20, thereby realizing a configuration that can correct the position of the wiring material W when assembled to the base member 10. Each component of the protector 1 will be described in detail below with reference to Figs. 1 to 3.

[0017] In the following explanation, Orthogonal Of the first, second, and third directions, the first direction is referred to as the "length direction X," the second direction is referred to as the "width direction Y," and the third direction is referred to as the "height direction Z." The length direction X, width direction Y, and height direction Z are mutually perpendicular. The length direction X typically corresponds to the insertion direction of the wiring material W into the protector 1, etc. Furthermore, the height direction Z corresponds to the attachment / detachment direction of the cover member 20 with respect to the base member 10, the opening direction of the opening 14 (described later) of the base member 10, etc. Unless otherwise specified, each direction used in the following description will be described as the direction when each part of the protector 1 is assembled.

[0018] In addition, the upper side in the height direction Z corresponds to the side where the cover member 20 is located when each part of the protector 1 is assembled, and the lower side in the height direction Z corresponds to the side where the base member 10 is located when each part of the protector 1 is assembled.

[0019] 1 to 3, the base member 10 includes a bottom wall portion 11 and side wall portions 12, 13 as a wall portion 10K. The base member 10 has a U-shaped cross section along the height direction Z, with the bottom wall portion 11 and the side wall portions 12, 13 being integrated together. Therefore, the base member 10 has a storage space portion 10S (see FIGS. 1 and 3) as an internal space, an opening portion 14 (see FIGS. 1 and 3) that opens in the height direction Z, and insertion opening portions 15A and 15B (see FIG. 2) that open in the length direction X.

[0020] The bottom wall portion 11 extends along the axial direction X and the width direction Y, and is formed in a substantially rectangular plate shape with the height direction Z being the plate thickness direction. The bottom wall portion 11 is disposed opposite the opening 14 at a distance from the opening 14 along the height direction Z, which is the opening direction of the opening 14.

[0021] The side walls 12 and 13 extend along the axial direction X and the height direction Z, are formed in a substantially rectangular plate shape with the width direction Y being the plate thickness direction, and are disposed at an interval along the width direction Y intersecting with the opening direction of the opening 14, and are positioned opposite each other. The side walls 12 and 13 are connected to both ends of the bottom wall 11 in the width direction Y. More specifically, the side wall 12 stands upright from one end of the bottom wall 11 in the width direction Y along the height direction Z, and the side wall 13 stands upright from the other end of the bottom wall 11 in the width direction Y along the height direction Z. The side walls 12 and 13 referred to here each have various shapes including a concave portion, a convex portion, a curved portion, or a bent portion.

[0022] The storage space 10S is a portion partitioned and formed by the bottom wall 11 and a pair of side walls 12 and 13. The protector 1 can route the wiring material W along the length direction X by inserting the wiring material W into the storage space 10S through the insertion openings 15A and 15B located at the ends of the length direction X. The storage space 10S here means a portion that can hold the wiring material W by any of the bottom wall 11, the side wall 12, and the side wall 13. Therefore, the storage space 10S includes a space surrounded by multiple walls, a space partitioned by walls located opposite each other, a space located along a wall surface of one wall, and the like.

[0023] The opening 14 is a portion defined and formed by a pair of side walls 12, 13, and is a portion sandwiched between the ends of the side walls 12, 13 located at the upper side in the height direction Z. When the cover member 20 is assembled to the base member 10, the protector 1 of this embodiment closes a portion of the opening 14 with the cover member 20, and covers a portion of the storage space 10S located corresponding to the opening 14. Therefore, the protector 1 has a portion that holds the wiring material W by storing the wiring material W in an internal space surrounded by the wall portion 10K of the base member 10 and the wall portion 20K (described later) of the cover member 20, and a portion that holds the wiring material W only with the wall portion 10K.

[0024] The insertion openings 15A, 15B are portions defined and formed by a pair of side wall portions 12, 13, and are portions sandwiched between the ends of each side wall portion 12, 13 located on the base end side (left side in FIG. 2) and the tip end side (right side in FIG. 2) in the longitudinal direction X.

[0025] On the other hand, the cover member 20 is constituted by a wall portion 20K as shown in Figs. 1 to 3. The cover member 20 extends from one side wall portion 12 to the other side wall portion 13 in a state where it is assembled to the base member 10, and is formed to a size capable of closing the opening 14 of the base member 10 in the width direction Y. The cover member 20 can partially close the opening 14 along the length direction X, and is formed in a plate shape in which the height direction Z is the plate thickness direction in a state where the opening 14 is closed (see Fig. 2, etc.). At this time, the cover member 20 is held in a closing position where the opening 14 of the base member 20 is closed by being locked to each side wall portion 12, 13 of the base member 10 via a locking mechanism 30, and is disposed at an interval from the bottom wall portion 11 along the height direction Z and positioned opposite to it.

[0026] The locking mechanism 30 includes a plurality of locking pieces 31 provided on each of the side walls 12, 13 of the base member 10, and locked pieces 32 provided on the cover member 20 to correspond to each of the locking pieces 31 (see Figs. 1, 3, etc.). The base member 10 can lock the cover member 20 via the locking mechanism 30 by locking a protrusion formed on the locked piece 32 of the cover member 20 with a hole formed in each of the locking pieces 31.

[0027] Next, the configuration of the positioning portion 200 provided on the cover member 20 will be described.

[0028] The positioning portion 200 is a portion formed to protrude from the inner surface side of the cover member 20. The positioning portion 200 has a protruding portion 210 and a pressing flat portion 220 provided at the tip of the protruding portion 210, as shown in FIG.

[0029] The protruding portions 210 extend along the length direction X when the cover member 20 is assembled to the base member 10, and also extend between the pair of side wall portions 12, 13 in the width direction Y. Furthermore, when the cover member 20 is assembled to the base member 10, the protruding portions 210 are formed in the height direction Z along each of the side wall portions 12, 13. Therefore, when the cover member 20 is assembled to the base member 10, the storage space portion 10S of the base member 10 is narrowed by the protruding portions 210.

[0030] When the cover member 20 is assembled to the base member 10, the pressing flat portion 220 extends along the axial direction X and the width direction Y, and is positioned opposite the bottom wall portion 11 of the base member 10. Therefore, when the cover member 20 is assembled to the base member 10, the height of the storage space portion 10S of the base member 10 is narrowed by the pressing flat portion 220 of the protruding portion 210, and the height (the distance from the bottom wall portion 11 to the pressing flat portion 220) is narrowed to a predetermined height through which each of the wiring materials W can be inserted.

[0031] Next, the operation of assembling the protector 1 will be described.

[0032] First, the worker assembles a plurality of wiring materials W to the base member 10. Then, the worker assembles the cover member 20 to the base member 10 with each of the wiring materials W inserted into the storage space portion 10S of the base member 10. At this time, when the positioning portion 200 of the cover member 20 is inserted from the opening portion 14 of the base member 10, the pressing plane portion 220 is abutted against each of the wiring materials W stored in the storage space portion 10S and is pushed toward the bottom wall portion 11 of the base member 10. Therefore, the cover member 20 can move each of the wiring materials W stored in the storage space portion 10S toward the bottom wall portion 11 of the base member 10 via the positioning portion 200. Therefore, according to the protector 1 in which the cover member 20 is assembled to the base member 10 in this manner, each of the wiring materials W is arranged between the positioning portion 200 of the cover member 20 and the bottom wall portion 11 of the base member 10, and the wiring material W is sandwiched between the positioning portion 200 and the bottom wall portion 11, so that the position of the wiring material W in the storage space portion 10S can be corrected. Furthermore, when the cover member 20 is assembled to the base member 10, the height of the storage space portion 10S is narrowed by the pressing flat portion 220 of the protruding portion 210, and the height is narrowed until it becomes equal to the height of the wiring material W. Therefore, in the protector 1, with the cover member 20 assembled to the base member 10, each of the wiring materials W can be arranged side by side along the width direction Y (see FIG. 3).

[0033] Furthermore, when the cover member 20 of the protector 1 is assembled to the base member 10, the positioning portion 200 of the cover member 20 can block the opening 14 of the base member 10 in the width direction Y. Therefore, the cover member 20 can prevent each of the wiring materials W stored in the storage space portion 10S from moving toward the opening 14 and jumping out of the opening 14 to the outside.

[0034] The wire harness WH described above includes a conductive wiring material W, a storage space 10S formed by a wall portion 10K and through which the wiring material W is inserted, a base member 10 having an opening 14 connecting the storage space 10S with the outside, and a protector 1 having a cover member 20 that closes the opening 14 by being assembled to the base member 10. The cover member 20 has a positioning portion 200 that is formed to protrude toward the storage space 10S side when assembled to the base member 10 and abuts against the wiring material W stored in the storage space 10S, and the positioning portion 200 can correct the position of the wiring material W when assembled to the base member 10.

[0035] According to this configuration, the wire harness WH and the protector 1 can press each of the wiring materials W stored in the storage space 10S from the opening 14 side by pushing the positioning portion 200 of the cover member 20 through the opening 14 of the base member 10. Therefore, the wire harness WH and the protector 1 can hold and store the wiring materials W at appropriate positions in the storage space 10S.

[0036] Furthermore, the wire harness WH and the base member 10 of the protector 1 described above include, as the wall portion 10K, a bottom wall portion 11 located opposite the opening 14 along the opening direction (height direction Z) of the opening 14, and a pair of side wall portions 12, 13 extending from both ends of the bottom wall portion 11 and facing each other along a width direction Y that intersects with the height direction Z. In addition, the positioning portion 200 has a protrusion portion 210 that extends between the pair of side wall portions 12, 13 in the width direction Y and is formed along each of the side wall portions 12, 13 in the height direction Z when the cover member 20 is assembled to the base member 10, and a pressing flat portion 220 that is provided at the tip of the protrusion portion 210 and faces the bottom wall portion 11 when the cover member 20 is assembled to the base member 10, and arranges each of the wiring materials W between the pressing flat portion 220 and the bottom wall portion 11 in the width direction Y when the cover member 20 is assembled to the base member 10. According to this configuration, the wire harness WH and the protector 1 can move each of the wiring materials W stored in the storage space portion 10S toward the bottom wall portion 11 through the protrusion portion 210 of the positioning portion 200, thereby preventing the wiring materials W from moving toward the opening 14 and jumping out of the opening 14 to the outside. In addition, the wire harness WH and the protector 1 can correct the position of the wiring material W via the pressing flat portion 220 of the protruding portion 210 so that each of the wiring materials W is arranged along a predetermined direction in the storage space portion 10S. Therefore, the wire harness WH and the protector 1 can prevent the wiring materials W from becoming entangled with each other due to the movement of each wiring material W in the storage space portion 10S when the movable part to which the wiring material W is connected is operated. Therefore, the wire harness WH and the protector 1 can hold and store the wiring material W in the appropriate position in the storage space portion 10S.

[0037] [Second embodiment] Next, a wire harness WHA according to a second embodiment will be described. The wire harness WHA differs from the wire harness WH and the protector 1 according to the first embodiment in the shape of a positioning portion 200A provided on a cover member 20A of a protector 1A. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0038] The positioning portion 200A is a portion formed to protrude from the inner surface side of the cover member 20A. The positioning portion 200A has a protruding portion 210 and a notched portion 230 provided on the tip side of the protruding portion 210, as shown in FIG.

[0039] The cutout portion 230 is a groove portion formed from the tip side toward the base end side of the protrusion portion 210, and is formed from the bottom wall portion 11 side of the base member 10 toward the opening portion 14 side when the cover member 20 is assembled to the base member 10. The protrusion portion 210 in which the groove portion is formed has a U-shaped cross section along the height direction Z, and a pair of protrusions are formed on both sides of the cutout portion 230. Therefore, when the cover member 20 is assembled to the base member 10, the storage space portion 10S of the base member 10 is narrowed by the protrusion portion 210, and the storage space portion 10S becomes a space portion surrounded by the cutout portion 230 (the inside of the cutout portion 230).

[0040] According to such a structure, the wire harness WHA and the protector 1A guide each of the wiring materials W stored in the storage space 10S of the base member 10 to the inside of the cutout portion 230 and move it toward the center of the storage space 10S, thereby preventing the wiring materials W from moving toward the opening 14 and jumping out of the opening 14. Therefore, the wire harness WHA and the protector 1A can hold and store the wiring materials W at an appropriate position in the storage space 10S.

[0041] The protectors 1, 1A and the wire harnesses WH, WHA according to the above-described embodiments of the present invention are not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.

[0042] For example, the positioning portion has been described as being formed in the longitudinal direction X and extending from one insertion opening formed by the base member to the other insertion opening when the cover member is assembled to the base member, but the position of the positioning portion with respect to the longitudinal direction X is not particularly limited.

[0043] Furthermore, the positioning portion does not have to have a flat pressing portion, and does not have to have a notch portion.

[0044] The protector and the wire harness according to this embodiment may be configured by appropriately combining the components of the embodiment and modified examples described above. [Explanation of symbols]
