[Technical field]
[0001] The present disclosure relates to a protector and a wire harness. [Background technology]
[0002] Conventionally, some wire harnesses include an electric wire member and a protector having a cylindrical portion that covers the electric wire member (see, for example, Patent Document 1). The cylindrical portion has a base portion that covers a part of the circumference of the electric wire member, and a lid that covers the entire circumference of the electric wire member together with the base portion. The base portion has a fitted portion, and the lid has a fitting portion that is fitted into the fitted portion by movement along a direction intersecting the length direction of the cylindrical portion. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2012-235575 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the above protector, the cover is fitted to the fitted part by the movement of the fitting part along a direction intersecting the length direction of the cylindrical part, so that the cover is likely to rattle in the direction in which the fitting part is fitted, specifically, in the direction intersecting the length direction of the cylindrical part relative to the base. Therefore, for example, when the electric wire member is suddenly bent outside the cylindrical part, if the electric wire member applies a force in a direction in which the cover moves away from the base, there is a risk that the cover will be slightly separated from the base. In particular, in a configuration in which the length of the cylindrical part is long and the fitting part is provided at a part of the length direction of the cylindrical part, there is a risk that the end of the cylindrical part in the length direction of the cover will be significantly separated from the base, in other words, will be significantly lifted up. Therefore, there is a risk that the path of the electric wire member will deviate from the normal path, and for example, the electric wire member will come into contact with other surrounding parts.
[0005] An object of the present disclosure is to provide a protector and a wire harness capable of maintaining the path of an electric wire member in a normal path. [Means for solving the problem]
[0006] The protector of the present disclosure has a tubular portion that covers an electric wire member, the tubular portion having a base that covers a portion of the circumference of the electric wire member, a first lid that, together with the base, covers the entire circumference of the electric wire member, and a second lid that is disposed at a position offset from the first lid in the longitudinal direction of the tubular portion and covers the entire circumference of the electric wire member together with the base, the base having a rail portion and a mating portion, the first lid having a sliding portion that fits into the rail portion by sliding movement in a first direction along the longitudinal direction of the tubular portion, and the second lid having a mating portion that is mated into the mating portion by movement along a direction intersecting the longitudinal direction of the tubular portion, and when the mating portion is mated to the mating portion, the mating portion prevents sliding movement of the first lid in a second direction that is opposite to the first direction.
[0007] The wire harness of the present disclosure includes the protector and the electric wire member. Effect of the Invention
[0008] According to the protector and the wire harness of the present disclosure, the path of the electric wire members can be maintained in a normal path. [Brief description of the drawings]

[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The protector of the present disclosure includes: [1] A cylindrical portion that covers an electric wire member, the cylindrical portion having a base that covers a portion of the circumference of the electric wire member, a first lid that covers the entire circumference of the electric wire member together with the base, and a second lid that is offset from the first lid in the longitudinal direction of the cylindrical portion and covers the entire circumference of the electric wire member together with the base, the base having a rail portion and a fitted portion, the first lid having a sliding portion that fits into the rail portion by sliding movement in a first direction along the longitudinal direction of the cylindrical portion, the second lid having a fitting portion that is fitted into the fitted portion by movement along a direction intersecting the longitudinal direction of the cylindrical portion, and when the fitting portion is fitted into the fitted portion, the fitting portion prevents sliding movement of the first lid in a second direction that is opposite to the first direction.
[0011] According to this configuration, the first lid is configured such that the slide portion fits into the rail portion of the base by sliding in the first direction along the length direction of the cylindrical portion, so that the slide portion can be engaged with the rail portion in a direction intersecting the length direction of the cylindrical portion over a long range in the length direction of the cylindrical portion. Therefore, the first lid is prevented from rattling in a direction intersecting the length direction of the cylindrical portion relative to the base. Therefore, even if the first lid receives a force in a direction away from the base due to a bent electric wire member, the first lid is prevented from moving away from the base. Therefore, the electric wire member is prevented from moving away from the base, and the path of the electric wire member can be maintained as a normal path. As a result, for example, it is possible to prevent the electric wire member from coming into contact with other peripheral components. In addition, the second lid is fitted into the fitted portion of the base by moving along a direction intersecting the length direction of the cylindrical portion. Furthermore, when the fitting portion is fitted into the fitted portion, the second lid prevents the first lid from sliding in a second direction, which is the opposite direction to the first direction, thereby preventing the sliding portion fitted into the rail portion from coming out in the second direction.
[0012] [2] It is preferable that the second lid has an overlapping portion that overlaps with the first lid in a direction intersecting with the longitudinal direction of the cylindrical portion. According to this configuration, the second lid has an overlapping portion that overlaps with the first lid in a direction intersecting the longitudinal direction of the tubular portion, so that even if the first lid is subjected to a force in a direction moving away from the base, for example, by a bent electric wire member, the first lid is more likely to be prevented from separating from the base.
[0013] [3] It is preferable that the first lid has an engaged portion, and the overlapping portion has an engaging portion that engages with the engaged portion in the first direction and the second direction. According to this configuration, the overlapping portion has an engaging portion that engages with the engaged portion of the first lid in the first direction and the second direction, thereby preventing the sliding portion fitted into the rail portion from slipping out in the first direction and the second direction.
[0014] [4] It is preferable that the base has a terminal portion at an end of the rail portion on the first direction side, the terminal portion preventing movement of the slide portion. According to this configuration, the base has a terminal portion at the end of the rail portion on the first direction side that prevents the slide portion from moving, and the terminal portion prevents the slide portion fitted into the rail portion from slipping out in the first direction.
[0015] [5] It is preferable that the rail portion is provided so as to protrude outward from the base portion. According to this configuration, the rail portion is arranged to protrude outward from the base portion, so that there is no protrusion on the inside of the tubular portion compared to a configuration in which the rail portion protrudes inward, for example, and the electric wire member can be well accommodated in the tubular portion.
[0016] The wire harness of the present disclosure includes: [6] The protector and the electric wire member are included. According to this configuration, the path of the electric wire members in the wire harness can be maintained in a normal path.
[0017] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from one drawing to another. Note that the present disclosure is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this specification, "parallel" and "orthogonal" do not only refer to the cases of strictly parallel and orthogonal, but also generally refer to those within the range in which the action and effect of this embodiment is achieved. Parallel In addition, the terms "circle" and "arc" in this specification do not necessarily mean a strict circle or arc, but also include approximate circles and arcs within the scope of the effects of this embodiment.
[0018] (Overall configuration of the wire harness 10) 1, the wire harness 10 includes an electric wire member 11 and a protector 12. The wire harness 10 electrically connects a plurality of electric devices of a vehicle, for example.
[0019] (Configuration of electric wire member 11) The electric wire member 11 has an electric wire 21 and a corrugated tube 22 as an exterior member covering the electric wire 21. The corrugated tube 22 is formed in a cylindrical shape and has a bellows structure in which large diameter portions 23 and small diameter portions 24 are alternately provided in a row along the length direction.
[0020] (Configuration of Protector 12) The protector 12 has a cylindrical portion 31 that covers the electric wire member 11. The protector 12 of this embodiment has a curved middle portion so as to hold the electric wire member 11 in a bent state, and has cylindrical portions 31 at both ends.
[0021] In detail, the protector 12 has a base 32, two first lids 33, and two second lids . (Configuration of base 32) The base 32 covers a part of the circumferential direction of the electric wire member 11. In this embodiment, the base 32 covers half of the circumferential direction of the electric wire member 11. The cross section of the base 32 perpendicular to the length direction along the extension direction of the electric wire member 11 is arc-shaped, and both ends of the arc shape form open ends 35. The base 32 has a curved portion 36 in the middle in the length direction. The curved portion 36 is the outside of the electric wire member 11 in a bent state, in other words, it covers the side with a larger radius of curvature.
[0022] The base 32 has a rail portion 37 and a fitted portion 38. The rail portion 37 and the fitted portion 38 are provided on both ends of the base 32 in the length direction, respectively. As shown in Figs. 2 and 3, the rail portion 37 is provided adjacent to the open end 35. The rail portion 37 is provided so as to protrude outside the base 32, in other words, radially outward from the tubular portion 31. The rail portion 37 extends along the length of the base 32. The rail portion 37 has a groove 39 extending along the length of the base 32. Also, as shown in Fig. 2, the base 32 has a terminal portion 40 at one end of the rail portion 37. The terminal portion 40 is provided at the end of the rail portion 37 on the curved portion 36 side of the base 32. The terminal portion 40 is provided so as to close the groove 39 of the rail portion 37, and is the terminal end of the groove 39.
[0023] As shown in Fig. 2, the fitted portion 38 is provided closer to the end in the longitudinal direction of the base portion 32 than the rail portion 37. As shown in Figs. 2 and 4, the fitted portion 38 is provided adjacent to the open end 35. The fitted portion 38 is provided to protrude outside the base portion 32, in other words, radially outward from the tubular portion 31. The fitted portion 38 has a fitting hole 41.
[0024] (Configuration of first cover 33) 1 , the first lid 33, together with the base 32, covers the entire circumferential direction of the electric wire member 11. In this embodiment, the first lid 33 covers half of the circumferential direction of the electric wire member 11. The first lid 33 has an arc-shaped cross section perpendicular to the length direction along the extension direction of the electric wire member 11, and both ends of the arc shape form open ends 42.
[0025] As shown in FIG. 2 and FIG. 3, the first lid 33 has a slide portion 43. As shown in FIG. 2, the slide portion 43 fits into the rail portion 37 by sliding in a first direction X1 along the length direction of the cylindrical portion 31. In this embodiment, the first direction X1 is a direction toward the center of the length direction of the base portion 32 and toward the curved portion 36. The slide portion 43 is provided adjacent to the opening end 42. The slide portion 43 is provided protruding inside the first lid 33, in other words, radially inside the cylindrical portion 31. The slide portion 43 is shaped to fit into the groove 39 of the rail portion 37, and the protruding amount, width, and length of the slide portion 43 are set corresponding to the depth, width, and length of the groove 39.
[0026] (Configuration of second cover 34) 1, the second lid 34 is provided at a position offset from the first lid 33 in the longitudinal direction of the tubular portion 31, and covers the entire circumferential direction of the electric wire member 11 together with the base portion 32. The second lid 34 of this embodiment covers half of the circumferential direction of the electric wire member 11. The second lid 34 has an arc-shaped cross section perpendicular to the longitudinal direction along the extension direction of the electric wire member 11, and both ends of the arc shape form open ends 44.
[0027] As shown in Figs. 2 and 4, the second lid 34 has a fitting portion 45. As shown in Fig. 2, the fitting portion 45 is fitted into the fitted portion 38 by movement along a direction Y1 intersecting the length direction of the cylindrical portion 31. In this embodiment, the direction Y1 is the radial direction of the cylindrical portion 31, which is the direction in which the open ends 35, 44 are brought close to each other and aligned. The fitting portion 45 is provided adjacent to the open end 44. The fitting portion 45 is provided protruding outside the second lid 34, in other words, outside the radial direction of the cylindrical portion 31. The fitting portion 45 has a claw 46 that is fitted into and locked in the fitting hole 41 of the fitted portion 38 by movement along a direction Y1 intersecting the length direction of the cylindrical portion 31.
[0028] As shown in FIG. 1, with the fitting portion 45 fitted into the fitted portion 38, the second lid 34 is arranged alongside the first lid 33 in the longitudinal direction of the tubular portion 31, and prevents the first lid 33 from sliding in the second direction X2, which is the opposite direction to the first direction X1.
[0029] The operation of this embodiment will be described. The electric wire member 11 is arranged such that half of the electric wire member 11 in the circumferential direction is covered by the base 32. The first lid 33 is slid in a first direction X1 along the length direction of the cylindrical portion 31, so that the slide portion 43 is fitted into the rail portion 37 of the base 32. The second lid 34 is moved in a direction Y1 intersecting the length direction of the cylindrical portion 31, so that the fitting portion 45 is fitted into the fitted portion 38 of the base 32. As a result, the electric wire member 11 is covered all around by the cylindrical portion 31 formed by the base 32, the first lid 33, and the second lid 34. The electric wire member 11 is held and protected by the protector 12 with the portion corresponding to the curved portion 36 bent.
[0030] Next, the effects of the above embodiment will be described below. (1) The first lid 33 is fitted into the rail portion 37 of the base 32 by sliding in the first direction X1 along the length direction of the cylindrical portion 31. Therefore, the slide portion 43 can be engaged with the rail portion 37 in a direction intersecting the length direction of the cylindrical portion 31 over a long range in the length direction of the cylindrical portion 31. Therefore, the first lid 33 is prevented from rattling in a direction intersecting the length direction of the cylindrical portion 31 relative to the base 32. Therefore, even if the first lid 33 receives a force in a direction away from the base 32 by the bent electric wire member 11, for example, the first lid 33 is prevented from being separated from the base 32. Therefore, the electric wire member 11 is prevented from being separated from the base 32, and the path of the electric wire member 11 can be maintained as a normal path. As a result, for example, the electric wire member 11 can be prevented from coming into contact with other peripheral components. Furthermore, the second lid 34 is moved along a direction Y1 intersecting the longitudinal direction of the cylindrical portion 31, so that the fitting portion 45 is fitted into the fitted portion 38 of the base portion 32. With the fitting portion 45 fitted into the fitted portion 38, the second lid 34 prevents the first lid 33 from sliding in the second direction X2, which is the opposite direction to the first direction X1, and therefore prevents the sliding portion 43 fitted into the rail portion 37 from slipping out in the second direction X2.
[0031] (2) The base 32 has a terminal end 40 at the end of the rail portion 37 on the first direction X1 side, which prevents the slide portion 43 from moving, and the terminal end 40 prevents the slide portion 43, which is fitted into the rail portion 37, from slipping out in the first direction X1.
[0032] (3) Since the rail portion 37 is provided so as to protrude outward from the base portion 32, it is possible to provide a configuration in which there is no protrusion on the inner side of the tubular portion 31 compared to a configuration in which the rail portion 37 is provided so as to protrude inward, and the electric wire member 11 can be accommodated well in the tubular portion 31.
[0033] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.
[0034] In the above embodiment, the rail portion 37 is provided so as to protrude outward from the base portion 32. However, this is not limited to this, and the rail portion 37 may be configured so as to protrude inward from the base portion 32. 5 and 6, the rail portion 51 may be configured to protrude inside the base 32, in other words, radially inward of the cylindrical portion 31. The rail portion 51 extends along the length of the base 32. The rail portion 51 has a groove 52 extending along the length of the base 32. The slide portion 53 of the first lid 33 is provided to protrude outside the first lid 33, in other words, radially outward of the cylindrical portion 31.
[0035] 7, the second cover 34 in this example is provided with a fitting portion 45 only on one opening end 44 side, and the other opening end 44 side is connected to the base 32 by a thin hinge portion 54. Even in this case, the same effects as the effects (1) and (2) of the above embodiment can be obtained.
[0036] The second lid 34 in the above embodiment may have an overlapping portion that overlaps with the first lid 33 in a direction intersecting with the length direction of the cylindrical portion 31 . For example, it may be modified as shown in FIG. 8. The first lid 33 in this example has a recess 61 on the outer surface of the end portion on the second lid 34 side. The second lid 34 in this example has an overlapping portion 62 that overlaps with the first lid 33 while fitting into the recess 61. The recess 61 may be provided on the entire circumferential direction of the first lid 33 or on a part of the circumferential direction. The overlapping portion 62 may be provided on the entire circumferential direction of the second lid 34 or on a part of the circumferential direction. In this way, for example, even if the first lid 33 receives a force in a direction in which it moves away from the base 32 due to the bent electric wire member 11, it is more likely that the first lid 33 will be prevented from moving away from the base 32.
[0037] Also, for example, it may be modified as shown in Fig. 9. The first lid 33 in this example has a recess 71 on the outer surface of the end on the second lid 34 side. The first lid 33 in this example has an engaged portion 72 recessed deeper into the recess 71. The second lid 34 in this example has an overlapping portion 73 that fits into the recess 71 and overlaps with the first lid 33. The overlapping portion 73 has an engaging portion 74 that fits into the engaged portion 72 and engages with the engaged portion 72 in the first direction X1 and the second direction X2.
[0038] Even in this case, for example, even if the first lid 33 receives a force in a direction in which the first lid 33 moves away from the base 32 due to the bent electric wire member 11, the first lid 33 is further prevented from moving away from the base 32. Also, the engaging portion 74 prevents the sliding portion 43 fitted in the rail portion 37 from coming off in the first direction X1 and the second direction X2. Note that, in this example, the base 32 may be configured not to have the terminal portion 40.
[0039] In the above embodiment, the protector 12 has two cylindrical portions 31, but is not limited thereto, and may have only one cylindrical portion 31, or may have three or more cylindrical portions 31. In addition, the protector 12 has one curved portion 36, but is not limited thereto, and may have two or more curved portions 36. In addition, the degree of curvature of the protector 12 shown in FIG. 1, more specifically, the degree of curvature of the curved portion 36, may be changed.
[0040] In the above embodiment, the electric wire member 11 has the electric wire 21 and the corrugated tube 22 as an exterior member, but is not limited thereto. For example, the exterior member may be a cylindrical member other than the corrugated tube 22. In addition, the electric wire member 11 may have a plurality of electric wires 21, and the plurality of electric wires 21 may be covered with the corrugated tube 22. [Explanation of symbols]
