[0009] Hereinafter, the wire cover according to the 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 can be easily assumed by those skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to FIGS. 1 to 8. This embodiment relates to a wire cover. FIG. 1 is a plan view of the wire cover according to the embodiment, FIGS. 2 to 5 are cross-sectional views of the wire cover according to the embodiment, FIG. 6 is a view showing a small-diameter corrugated tube held by the wire cover, FIG. 7 is a view showing a medium-diameter corrugated tube held by the wire cover, and FIG. 8 is a view showing a large-diameter corrugated tube held by the wire cover.

[0011] As shown in FIG. 1, the wire cover 1 of the present embodiment has an engaging portion 2 that engages with the connector 100 and a cylindrical portion 3. The wire cover 1 is a cylindrical member that protects the wire W drawn out from the connector 100. The wire cover 1 is formed of, for example, an insulating synthetic resin. The material of the wire cover 1 is, for example, polypropylene (PP) or nylon. The connector 100 holds terminals inside. The wire W connected to the terminals extends outside from the outlet portion 110 of the connector 100. The outlet portion 110 has a passage through which the wire W is inserted.

[0012] The engaging portion 2 engages with the outlet portion 110 of the connector 100. The engaging portion 2 may be fitted to the outlet portion 110 from the outside. An electric wire W extending from the connector 100 is inserted through the cylindrical portion 3. As will be described later, the cylindrical portion 3 has a plurality of holding portions 5 for holding the corrugated tube 200. The corrugated tube 200 is a flexible cylindrical exterior member that protects the electric wire W. The corrugated tube 200 is formed of, for example, an insulating synthetic resin.

[0013] The cross-sectional shape of the cylindrical portion 3 is a shape corresponding to the cross-sectional shape of the corrugated tube 200. The corrugated tube 200 of the present embodiment has a cylindrical shape. In this case, the cross-sectional shape of the cylindrical portion 3 is, for example, a cylindrical shape.

[0014] The corrugated tube 200 has a bellows shape. That is, the outer surface of the corrugated tube 200 has convex portions 200a and groove portions 200b that are alternately arranged along the axial direction of the corrugated tube 200. The convex portions 200a and the groove portions 200b are each formed in an annular shape.

[0015] As shown in FIG. 2, the wire cover 1 has a plurality of holding portions 5 for holding the corrugated tube 200. The plurality of holding portions 5 of the present embodiment include a first holding portion 5A, a second holding portion 5B, and a third holding portion 5C. The first holding portion 5A, the second holding portion 5B, and the third holding portion 5C have different diameters of the corrugated tube 200 to be locked. For example, the first holding portion 5A is configured to hold the corrugated tube 200 having the relatively largest diameter. The third holding portion 5C is configured to hold the corrugated tube 200 having the relatively smallest diameter. The second holding portion 5B is configured to hold the corrugated tube 200 having an intermediate diameter.

[0016] As shown in FIG. 2, the cylindrical portion 3 has an insertion port 3a into which the corrugated tube 200 is inserted. In the following description, in the axial direction X of the cylindrical portion 3, the side closer to the insertion port 3a is referred to as the inlet side X1, and the side farther from the insertion port 3a is referred to as the back side X2. The engaging portion 2 is connected to the end portion on the back side X2 of the cylindrical portion 3. The first holding portion 5A is arranged on the most inlet side X1 among the three holding portions 5. The third holding portion 5C is arranged on the most back side X2 among the three holding portions 5.

[0017] As shown in FIG. 3, each holding portion 5 has a holding structure 6. The holding structure 6 is composed of a pair of arms facing each other across the central axis Cx of the cylindrical portion 3. As shown in FIG. 3, the first holding portion 5A has a first holding structure 6A composed of a pair of first arms 10. The first holding portion 5A has two first holding structures 6A arranged in the axial direction X. That is, the first holding portion 5A has four first arms 10.

[0018] The second holding portion 5B has a second holding structure 6B composed of a pair of second arms 20. The second holding portion 5B has two second holding structures 6B arranged in the axial direction X. The third holding portion 5C has a third holding structure 6C composed of a pair of third arms 30. The third holding portion 5C has two third holding structures 6C arranged in the axial direction X.

[0019] Taking the first arm 10 as an example, the structure of each arm will be described. As shown in FIG. 4, the first arm 10 has an arm body 10a, a first locking protrusion 11, and a second locking protrusion 12. The arm body 10a protrudes from the inner surface 3b of the cylindrical portion 3 toward the central axis Cx of the cylindrical portion 3. The arm body 10a is formed to have flexibility and is elastically deformable. The arm body 10a has a curved shape that extends toward the back side X2 in the axial direction X as it approaches the central axis Cx from the inner surface 3b.

[0020] For each of the arms 10, 20, 30, the height L from the inner surface 3b of the cylindrical portion 3 to the tip of the arm body is set. The value of the height L of the first arm 10 is set to L1.

[0021] The first locking projection 11 and the second locking projection 12 project from the arm body 10a. The illustrated locking projections 11, 12 are integrally formed with the arm body 10a. The first locking projection 11 locks the corrugated tube 200 when the corrugated tube 200 to be held is inserted into the cylindrical portion 3. The second locking projection 12 locks the tip of the inserted corrugated tube 200 when the diameter of the corrugated tube 200 inserted into the cylindrical portion 3 is larger than the diameter of the corrugated tube 200 to be held.

[0022] The first locking projection 11 projects from the tip of the arm body 10a. The second locking projection 12 projects from a base portion close to the inner surface 3b of the arm body 10a. The shapes of the first locking projection 11 and the second locking projection 12 are tapered shapes whose widths become narrower toward the tip in the protruding direction from the arm body 10a. The tip of the first locking projection 11 may be chamfered. The first locking projection 11 having a chamfered shape is less likely to damage the electric wire W when the first locking projection 11 contacts the electric wire W.

[0023] The first locking projection 11 has a locking surface 11s. The locking surface 11s is a surface facing the back side X2 in the axial direction X. The locking surface 11s locks the convex portion 200a of the corrugated tube 200. The second locking projection 12 has a locking surface 12s. The locking surface 12s is a surface facing the inlet side X1 in the axial direction X. The locking surface 12s locks the tip of the corrugated tube 200. The locking surface 12s is, for example, a surface orthogonal to the central axis Cx.

[0024] The two first arms 10 constituting the first holding structure 6A are arranged with the first locking projections 11 facing each other. The first locking projection 11 of one first arm 10 projects toward the first locking projection 11 of the other first arm 10. Also, the two first arms 10 constituting the first holding structure 6A are arranged with the second locking projections 12 facing each other.

[0025] As shown in FIG. 5, the basic configuration of the second arm 20 and the basic configuration of the third arm 30 are the same as the configuration of the first arm 10. The second arm 20 has an arm body 20a, a first locking projection 21, and a second locking projection 22. The arm body 20a protrudes from the inner surface 3b of the cylindrical portion 3 toward the central axis Cx of the cylindrical portion 3. The arm body 20a is formed to have flexibility and is elastically deformable. The arm body 20a has a curved shape that curves toward the back side X2 in the axial direction X as it approaches the central axis Cx from the inner surface 3b. The value of the height L of the second arm 20 is L2.

[0026] The first locking projection 21 protrudes from the tip of the arm body 20a. The second locking projection 22 protrudes from the base of the arm body 20a. The first locking projection 21 has a locking surface 21s facing the back side X2. The second locking projection 22 has a locking surface 22s facing the entrance side X1.

[0027] The third arm 30 has an arm body 30a, a first locking projection 31, and a second locking projection 32. The arm body 30a protrudes from the inner surface 3b of the cylindrical portion 3 toward the central axis Cx of the cylindrical portion 3. The arm body 30a is formed to have flexibility and is elastically deformable. The arm body 30a has a curved shape that curves toward the back side X2 in the axial direction X as it approaches the central axis Cx from the inner surface 3b. The value of the height L of the third arm 30 is L3.

[0028] The first locking projection 31 protrudes from the tip of the arm body 30a. The second locking projection 32 protrudes from the base of the arm body 30a. The first locking projection 31 has a locking surface 31s facing the back side X2. The second locking projection 32 has a locking surface 32s facing the entrance side X1.

[0029] In the wire cover 1 of the present embodiment, the values L1, L2, and L3 of the height L of the arms 10, 20, and 30 are set as in the following formula (1). That is, the third arm 30 protrudes to a position closer to the central axis Cx than either the first arm 10 or the second arm 20. Also, the second arm 20 protrudes to a position closer to the central axis Cx than the first arm 10. L1 < L2 < L3 (1)

[0030] In other words, the interval between the pair of first arms 10 in the first holding structure 6A is the widest, and the interval between the pair of third arms 30 in the third holding structure 6C is the narrowest. Therefore, the first holding structure 6A can hold a corrugated tube 200 with a relatively large diameter, and the third holding structure 6C can hold a corrugated tube 200 with a relatively small diameter. Also, the second holding structure 6B can hold a corrugated tube 200 with an intermediate diameter.

[0031] FIG. 6 shows a small-diameter corrugated tube 200S held by the wire cover 1. The corrugated tube 200S is the corrugated tube 200 to be held by the third holding structure 6C. The corrugated tube 200S has a diameter D3. The value of the diameter D3 is such that the corrugated tube 200S can pass through the first holding structure 6A and the second holding structure 6B and is held by the third holding structure 6C.

[0032] The corrugated tube 200S is inserted into the cylindrical portion 3 from the insertion port 3a toward the back side X2. The electric wire W is inserted through the corrugated tube 200S in advance. In other words, the tip portion of the electric wire W exposed from the corrugated tube 200S is connected to the connector 100. Thereafter, the wire cover 1 is attached to the connector 100, and the corrugated tube 200S is inserted into the wire cover 1. The wire cover 1 may be attached to the connector 100 so as to sandwich the outlet portion 110 of the connector 100. In this case, the wire cover 1 may be composed of two members or may be divided into two parts connected via a hinge or the like.

[0033] The first holding structure 6A allows the corrugated tube 200S to advance to the back side X2 beyond the first holding structure 6A. In the illustrated wire cover 1, the interval between the pair of first arms 10 is larger than the diameter D3 of the corrugated tube 200S. The second holding structure 6B allows the corrugated tube 200S to advance to the back side X2 beyond the second holding structure 6B. In the illustrated wire cover 1, the interval between the pair of second arms 20 is slightly smaller than the diameter D3 of the corrugated tube 200S. In this case, the second arm 20 allows the passage of the corrugated tube 200S by elastically deforming.

[0034] The third holding structure 6C is configured to hold the corrugated tube 200S. The interval between the pair of third arms 30 is smaller than the diameter D3 of the corrugated tube 200S. The corrugated tube 200S is inserted between the pair of third arms 30 while deflecting the third arms 30. At this time, the first locking protrusion 31 of the third arm 30 overrides the convex portion 200a of the corrugated tube 200S while deforming the arm body 30a, and engages with the groove portion 200b. When the corrugated tube 200S is further pushed into the back side X2, the first locking protrusion 31 overrides the next convex portion 200a and engages with the next groove portion 200b. Therefore, when the corrugated tube 200S is inserted between the pair of third arms 30, a sense of moderation is generated. Thus, it is easily recognized that the third arm 30 is engaged with the corrugated tube 200S.

[0035] The first locking protrusion 31 engaged with the groove portion 200b of the corrugated tube 200S locks the corrugated tube 200S by the locking surface 31s. The locking surface 31s restricts the movement of the corrugated tube 200S toward the inlet side X1 and serves as a retaining means against the removal of the corrugated tube 200S. The third holding structure 6C holds the corrugated tube 200S by sandwiching the corrugated tube 200S between a pair of third arms 30. The third holding portion 5C has two third holding structures 6C arranged in the axial direction X. The third holding portion 5C can stably hold the corrugated tube 200S by the two third holding structures 6C. Further, the third holding portion 5C can appropriately lock the corrugated tube 200S by the four first locking protrusions 31.

[0036] FIG. 7 shows a medium-diameter corrugated tube 200M held by the wire cover 1. The corrugated tube 200M is the corrugated tube 200 to be held by the second holding structure 6B. The corrugated tube 200M has a diameter D2. The diameter D2 is larger than the diameter D3 of the corrugated tube 200S. The value of the diameter D2 is such that the corrugated tube 200M can pass through the first holding structure 6A, is held by the second holding structure 6B, and the insertion of the corrugated tube 200M into the third holding structure 6C is restricted.

[0037] The corrugated tube 200M is inserted into the cylindrical portion 3 from the insertion port 3a toward the back side X2. The first holding structure 6A allows the corrugated tube 200S to advance to the back side X2 beyond the first holding structure 6A. In the illustrated wire cover 1, the interval between the pair of first arms 10 is slightly smaller than the diameter D2 of the corrugated tube 200M. In this case, the first arms 10 allow the passage of the corrugated tube 200M by elastically deforming.

[0038] The second holding structure 6B is configured to hold the corrugated tube 200M. The distance between the pair of second arms 20 is smaller than the diameter D2 of the corrugated tube 200M. The corrugated tube 200M is inserted between the pair of second arms 20 while deforming the second arms 20. At this time, the first locking protrusion 21 of the second arm 20 gets over the convex portion 200a of the corrugated tube 200M while deforming the arm main body 20a and engages with the groove portion 200b. When the corrugated tube 200M is further pushed into the deeper side X2, the first locking protrusion 21 gets over the next convex portion 200a and engages with the next groove portion 200b. Therefore, when the corrugated tube 200M is inserted between the pair of second arms 20, a sense of moderation is generated. Thus, it is easily recognized that the second arm 20 is engaged with the corrugated tube 200M.

[0039] The first locking protrusion 21 engaged with the groove portion 200b of the corrugated tube 200M locks the corrugated tube 200M by the locking surface 21s. The locking surface 21s restricts the movement of the corrugated tube 200M toward the inlet side X1 and serves as a retaining means against the corrugated tube 200M. The second holding structure 6B holds the corrugated tube 200M by sandwiching the corrugated tube 200M between the pair of second arms 20.

[0040] The second locking protrusion 32 of the third holding structure 6C functions as a stopper for locking the corrugated tube 200M. As shown in FIG. 7, the locking surface 32s of the second locking protrusion 32 faces the tip of the corrugated tube 200M in the axial direction X and locks the tip. By the corrugated tube 200M being locked by the locking surface 32s, it is recognized that the corrugated tube 200M has reached the deepest position X2 where it can be inserted.

[0041] FIG. 8 shows a large-diameter corrugated tube 200L held by the wire cover 1. The corrugated tube 200L is the corrugated tube 200 to be held by the first holding structure 6A. The corrugated tube 200L has a diameter D1. The diameter D1 is larger than the diameter D2 of the corrugated tube 200M. The value of the diameter D1 is such that the corrugated tube 200L is held by the first holding structure 6A and the insertion of the corrugated tube 200L into the second holding structure 6B is restricted.

[0042] The corrugated tube 200L is inserted into the cylindrical portion 3 from the insertion port 3a toward the back side X2. The first holding structure 6A is configured to hold the corrugated tube 200L. The distance between the pair of first arms 10 is smaller than the diameter D1 of the corrugated tube 200L. The corrugated tube 200L is inserted between the pair of first arms 10 while deforming the first arms 10. At this time, the first locking projection 11 of the first arm 10 gets over the convex portion 200a of the corrugated tube 200L while deforming the arm body 10a and engages with the groove portion 200b. When the corrugated tube 200L is further pushed into the back side X2, the first locking projection 11 gets over the next convex portion 200a and engages with the next groove portion 200b. Therefore, when the corrugated tube 200L is inserted between the pair of first arms 10, a sense of moderation is generated. Thus, it is easily recognized that the first arm 10 is engaged with the corrugated tube 200L.

[0043] The first locking projection 11 engaged with the groove portion 200b of the corrugated tube 200L locks the corrugated tube 200L by the locking surface 11s. The locking surface 11s restricts the movement of the corrugated tube 200L toward the entrance side X1 and serves as a retaining means for the corrugated tube 200L. The first holding structure 6A holds the corrugated tube 200L by sandwiching the corrugated tube 200L between the pair of first arms 10.

[0044] The second locking projection 22 of the second holding structure 6B functions as a stopper for locking the corrugated tube 200L. As shown in FIG. 8, the locking surface 22s of the second locking projection 22 faces the tip of the corrugated tube 200L in the axial direction X and locks the tip. When the corrugated tube 200L is locked by the locking surface 22s, it is recognized that the corrugated tube 200L has reached the deepest position X2 where it can be inserted.

[0045] When a corrugated tube 200 having a diameter larger than the diameter to be held by the first holding structure 6A is inserted into the cylindrical portion 3, the locking surface 12s of the first arm 10 functions as a stopper for locking the inserted corrugated tube 200.

[0046] As described above, the wire cover 1 of the present embodiment has an engaging portion 2 that engages with the connector 100, a cylindrical portion 3, and a plurality of holding portions 5. The wire W extending from the connector 100 is inserted through the cylindrical portion 3. The holding portion 5 is configured to be able to hold the corrugated tube 200 inserted into the cylindrical portion 3. The plurality of holding portions 5 have different diameters of the corrugated tubes 200 to be held. Each holding portion 5 has a holding structure 6 composed of a pair of arms 10, 20, 30 facing each other with the central axis Cx of the cylindrical portion 3 interposed therebetween. The arms 10, 20, 30 have flexible arm bodies 10a, 20a, 30a and locking projections protruding from the arm bodies 10a, 20a, 30a. The arm bodies 10a, 20a, 30a protrude from the inner surface 3b of the cylindrical portion 3 toward the central axis Cx. The arms 10, 20, 30 lock the corrugated tube 200 by the locking projections.

[0047] The arm of the holding structure 6 that holds the relatively small-diameter corrugated tube 200 protrudes to a position closer to the central axis Cx compared to the arm of the holding structure 6 that holds the relatively large-diameter corrugated tube 200. The cylindrical portion 3 has an insertion port 3a into which the corrugated tube 200 is inserted. The holding structure 6 that holds the relatively small-diameter corrugated tube 200 is arranged on the far side X2 from the insertion port 3a in the cylindrical portion 3 compared to the holding structure 6 that holds the relatively large-diameter corrugated tube 200. The wire cover 1 of the present embodiment has a plurality of holding portions 5 for holding corrugated tubes 200 with different diameters, so that it can correspond to corrugated tubes 200 with different thicknesses.

[0048] The locking protrusions of the arms 10, 20, 30 include first locking protrusions 11, 21, 31 and second locking protrusions 12, 22, 32. The first locking protrusions 11, 21, 31 engage with the groove portion 200b of the corrugated tube 200 when the corrugated tube 200 to be held is inserted into the cylindrical portion 3 to lock the corrugated tube 200. The second locking protrusions 12, 22, 32 lock the tip of the inserted corrugated tube 200 when the diameter of the corrugated tube 200 inserted into the cylindrical portion 3 is larger than the diameter of the corrugated tube 200 to be held. The arms 10, 20, 30 having the first locking protrusions 11, 21, 31 and the second locking protrusions 12, 22, 32 can position the inserted corrugated tube 200 at an appropriate position.

[0049] Note that the number of the holding portions 5 of the wire cover 1 is not limited to the three exemplified. For example, the wire cover 1 may have two holding portions 5 or may have four or more holding portions 5. The number of the locking protrusions of the arms 10, 20, 30 is not limited to two. For example, each of the arms 10, 20, 30 may have three or more locking protrusions. The wire cover 1 may have a stopper that functions in the same manner as the second locking protrusions 12, 22, 32. In this case, the stopper may be provided independently of the arms 10, 20, 30.

[0050] The content disclosed in the above embodiments can be executed in appropriate combination.
