  The perspective view of FIG. 1 and sectional drawing of FIG. 2 show typically the protector 1000 for wire harnesses of this embodiment.

  As shown in FIGS. 1 and 2, the wire harness protector 1000 includes a wire harness housing 1020, a lid 1021, a thin hinge 1022, a female lock 1023, a male lock 1024, a leaf spring 1025, and a flange 1026. The wire harness protector 1000 may include a component other than these components.

  The wire harness protector 1000 is preferably a single piece, and more preferably a single piece made of resin. Thereby, the manufacturing cost of the protector 1000 for wire harnesses falls. However, the wire harness protector 1000 may be a combined body of two or more members. Part or all of the wire harness protector 1000 may be made of a material other than resin. For example, part or all of the wire harness protector 1000 may be made of metal, ceramics, or the like.

  The wire harness container 1020 includes a bottom wall 1040, a first side wall 1041, and a second side wall 1042.

  A groove 1060 is formed in the wire harness container 1020. The extending direction of the groove 1060 may be straight or may be curled. As shown in FIG. 2, it is planned to accommodate the wire harness 1080 in the groove 1060. When the wire harness 1080 is accommodated in the groove 1060, the wire harness 1080 extends along the groove 1060.

  Of the four directions perpendicular to the direction in which the groove 1060 extends, three are surrounded by the bottom wall 1040, the first side wall 1041, and the second side wall 1042, and one is an opening 1100. The wire harness 1080 is protected by the bottom wall 1040, the first side wall 1041, and the second side wall 1042.

  The wire harness 1080 is accommodated in the groove 1060 via the opening 1100. Thereby, the protector 1000 for wire harnesses is easily mounted | worn with the wire harness 1080 compared with the case where the wire harness 1080 is passed through a cylindrical thing.

  The lid 1021 can rotate between a state in which the opening 1100 indicated by a solid line in FIG. 2 is closed and a state in which the opening 1100 indicated by a dashed line in FIG. 2 is not closed. When the lid 1021 closes the opening 1100, the first side 1120 of the lid 1021 is disposed along the upper end 1140 of the first side wall 1041, and the second side 1121 of the lid 1021 is the second side. It is disposed along the upper end 1160 of the side wall 1042. When the lid 1021 does not block the opening 1100, the first side 1120 of the lid 1021 is separated from the upper end 1140 of the first side wall 1041, but the second side 1121 of the lid 1021 is the second side wall. It is hardly separated from the upper end 1160 of 1042. The upper end 1140 of the first side wall 1041 and the upper end 1160 of the second side wall 1042 are on both sides of the opening 1100 and extend in the direction in which the groove 1060 extends.

  The lid 1021 rotates around the thin hinge 1022 as an axis. The thin hinge 1022 extends along the upper end portion 1160 of the second side wall 1042 in the direction in which the groove 1060 extends.

  A thin hinge 1022 couples the second side 1121 of the lid 1021 to the upper end 1160 of the second side wall 1042. The second side portion 1121 of the lid 1021 may be coupled to a position slightly away from the upper end portion 1160 of the second side wall 1042.

  The thickness of the thin hinge 1022 is thinner than the thickness of the lid 1021 and the thickness of the second side wall 1042, and the rigidity of the thin hinge 1022 is lower than the rigidity of the lid 1021 and the rigidity and the second side wall 1042. For this reason, the thin hinge 1022 is easily deformed. When the second side portion 1121 of the lid 1021 is coupled to the second side wall 1042 by the thin-walled hinge 1022 that is easily deformed, the lid 1021 can rotate about the thin-walled hinge 1022.

  When the wire harness protector 1000 is a combination of two or more members, the thin hinge 1022 may be replaced with another type of hinge. For example, the thin hinge 1022 may be replaced with a hinge including a shaft and a bearing. The thin hinge 1022 may be omitted. When the thin-walled hinge 1022 is omitted, preferably, a female lock 1023 is coupled to both the first side wall 1041 and the second side wall 1042, and the first side portion 1120 and the second side portion 1121 of the lid 1021 are coupled. A male lock 1024 is coupled to both.

  The female lock 1023 is coupled to the outer surface 1180 of the first side wall 1041. Thereby, the wire harness 1080 and the female lock 1023 do not interfere. However, the female lock 1023 may be coupled to the inner surface 1181 of the first side wall 1041.

  The female lock 1023 includes a hooking portion 1200, a first protruding portion 1201 (not shown in FIG. 2), and a second protruding portion 1202.

  The hook portion 1200 is coupled to the outer surface 1180 of the first side wall 1041 via the first protrusion 1201 and the second protrusion 1202. The hook portion 1200 may be coupled to the outer surface 1180 of the first side wall 1041 through a structure other than the first protrusion 1201 and the second protrusion 1202.

  The first protrusion 1201 and the second protrusion 1202 protrude from the outer surface 1180 of the first side wall 1041. The first protrusion 1201 and the second protrusion 1202 are separated in the direction in which the groove 1060 extends. The hook portion 1200 is bridged from the first protrusion 1201 to the second protrusion 1202. The hook portion 1200 extends in the direction in which the groove 1060 extends. Accordingly, a gap 1220 that penetrates in the direction 9000 in which the male lock 1024 is inserted into the female lock 1023 and the direction 9001 in which the male lock 1024 is removed from the female lock 1023 is formed between the hook portion 1200 and the outer surface 1180 of the first side wall 1041. A direction 9000 is a direction from the opening 1100 toward the bottom wall 1040. A direction 9001 is a direction from the bottom wall 1040 toward the opening 1100.

  The cross-sectional view of FIG. 3 schematically shows the vicinity of the female lock 1023.

  The hook portion 1200 is elastically deformed according to the applied stress. When stress in a direction 9002 that is perpendicular to the outer surface 1180 of the first side wall 1041 and is away from the outer surface 1180 of the first side wall 1041 is applied to the hooking portion 1200, as shown by a dashed line in FIG. The hooking portion 1200 is bent and the gap 1220 is wider than the steady distance D. When the stress in the direction 9002 is not applied to the hooking portion 1200 after the hooking portion 1200 is bent in the direction 9002, the deflection of the hooking portion 1200 in the direction 9002 is eliminated as shown by the solid line in FIG. Returns to the steady distance D. The steady distance D is the dimension of the gap 1220 in the direction 9002 when no stress is applied to the hook portion 1200.

  As shown in FIGS. 1 and 2, the male lock 1024 is coupled to the first side 1120 of the lid 1021. The male lock 1024 includes a root portion 1240 and a tip portion 1241. The root portion 1240 is coupled to the first side 1120 of the lid 1021.

  The cross-sectional view of FIG. 4 schematically shows the vicinity of the female lock 1023 and the male lock 1024.

  The maximum value (maximum thickness) of the thickness T1 of the root portion 1240 is thinner than the steady distance D, and the maximum value (maximum thickness) of the thickness T2 of the distal end portion 1241 is thicker than the steady distance D. For this reason, the root portion 1240 can pass through the gap 1220, and the tip end portion 1241 cannot pass through the gap 1220 unless the gap 1220 is expanded beyond the steady distance D.

  The perspective view of FIG. 5 schematically shows the vicinity of the leaf spring.

  As shown in FIG. 5, the leaf spring 1025 is coupled to the first side 1120 of the lid 1021. The leaf spring 1025 is disposed at a position where it hits the flange 1026 when the lid 1021 closes the opening 1100.

  The leaf spring 1025 may be replaced with another type of pressing mechanism. For example, the leaf spring 1025 may be replaced with a coil spring, a rubber piece, a foamed body piece, or the like. However, when the pressing mechanism is the leaf spring 1025, it becomes easy to form the pressing mechanism integrally with the lid 1021, and the manufacturing cost of the wire harness protector 1000 is reduced.

  The flange 1026 is coupled to the upper end 1140 of the first side wall 1041, projects from the upper end 1140 of the first side wall 1041, and is perpendicular to the first side wall 1040. Thereby, the surface pressed by the leaf spring 1025 is widened, and the first side wall 1041 is stably pressed.

  Although the first side wall 1041 is indirectly pressed through the heel 1026, the heel 1026 may be omitted and the first side wall 1041 may be pressed directly. When the first side wall 1041 is pressed directly, the leaf spring 1025 is disposed at a position where it hits the upper end 1140 of the first side wall 1040 when the lid 1021 closes the opening 1100.

  The perspective views from FIG. 6 to FIG. 9 and the cross-sectional view of FIG. 10 schematically show the vicinity of the leaf spring 1025.

  As shown in the dashed line in FIG. 2 and FIG. 6, the male lock 1024 is removed from the female lock 1023 when the lid 1021 does not block the opening 1100.

  When a force for inserting the male lock 1024 into the female lock 1023 is applied in a state where the lid 1021 does not block the opening 1100, the distal end portion 1241 enters the gap 1220 while bending the hook portion 1200 in the direction in which the gap 1220 expands. The tip portion 1241 finally passes through the gap 1220. The male lock 1024 is inserted into the female lock 1023, and the lid 1021 closes the opening 1100.

  As shown by the solid line in FIG. 2 and FIGS. 7 to 9, when the lid 1021 closes the opening 1100, the male lock 1024 is inserted into the female lock 1023, the root portion 1240 is disposed in the gap 1220, and the tip portion 1241 is disposed closer to the bottom wall 1040 than the gap 1220. Since the maximum thickness of the distal end portion 1241 is thicker than the steady distance D, when the lid 1021 closes the opening 1100, the distal end portion 1241 is not in the gap 1220 unless the hook portion 1200 is bent and the gap 1220 is wider than the steady distance D. The male lock 1024 cannot be removed from the female lock 1023. In a state where the lid 1021 closes the opening 1100, the wire harness 1080 is unlikely to deviate from the groove 1060.

  When the male lock 1024 is inserted into the female lock 1023 to the deepest, a gap 1260 is generated between the hook portion 1200 and the tip portion 1241. When there is no gap 1260, the male lock 1024 cannot be inserted into the female lock 1023 with a slight dimensional variation.

  When the lid 1021 closes the opening 1100, the leaf spring 1025 hits the flange 1026 and indirectly presses the first side wall 1041 via the flange 1026. A direction in which the leaf spring 1025 presses the first side wall 1041 is a direction 9001.

  As shown in FIG. 10, when the force for pressing the lid 1021 is not applied in a state where the male lock 1024 is inserted into the female lock 1023, the hook portion 1200 is pressed against the tip portion 1241, and the hook portion 1200 and the tip portion 1241. The gap 1260 between them disappears. Abnormal noise due to rattling is suppressed.

  The wire harness 1080 to which the wire harness protector 1000 is attached is typically attached to an automobile. The wire harness 1080 electrically connects two or more devices mounted on the automobile. The wire harness 1080 to which the wire harness protector 1000 is attached may be attached to a device other than the automobile. For example, the wire harness 1080 to which the wire harness protector 1000 is attached may be attached to a vehicle such as a motorcycle, a copying machine, or the like.

  The wire harness 1080 typically has a branch and electrically connects three or more devices. In some cases, the wire harness 1080 does not have a branch and electrically connects two devices.

  While the invention has been shown and described in detail, the above description is illustrative in all aspects and not restrictive. Accordingly, it is understood that numerous modifications and variations can be devised without departing from the scope of the present invention.
