It is formed in a cylindrical shape so as to overlap with a portion (hereinafter, the other side edge portion 51). The protection member 3 includes a hollow portion 30.

  In the present embodiment, the protection member 3 forms a state where the one side edge 41 including the one edge 4 overlaps the other edge 51 including the other edge 5 in the natural state. In the present embodiment, as shown in FIGS. 1 and 2, in the protective member 3 in the natural state, the other side edge is in a state where the one side edge 41 is in contact with the surface of the other side edge 51. The case where it overlaps on the part 51 is shown.

  However, in the protective member 3 in the natural state, the one end edge 41 is placed on the other end edge 51 in a state where a gap is formed between the one end edge 41 and the other end edge 51. It is also possible to overlap. In this case, in the protective member 3 in a state where the electric wire 2 is accommodated, it is preferable that a binding member such as a tape is wound around the protective member 3.

  The protection member 3 in the natural state means the protection member 3 in a state where no external force is applied.

  Moreover, in this embodiment, the one side edge part 41 is a part including the one edge 4 in the overlapping part in the protection member 3. The other side edge 51 is a part including the other edge 5 in the overlapping part of the protective member 3.

  The hollow portion 30 in the protection member 3 is a space in which the electric wire 2 can be inserted. In this embodiment, the cross-sectional shape of the hollow part 30 is circular. However, a case where the cross-sectional shape of the hollow portion 30 is a shape other than a circular shape such as a rounded rectangular shape or a rectangular shape is also conceivable.

  In the protection member 3, the one end edge 4 has a protruding portion 42, which is a portion protruding in the circumferential direction of the protection member 3 from one end portion of both end portions in the axial direction of the hollow portion 30, at one end. On the other end side of the part. Hereinafter, one end portion of the one end edge 4 is referred to as a start point portion 49. Further, the other end portion of the one end edge 4 is referred to as an end point portion 48. The axial center direction of the hollow portion 30 is also a direction that coincides with the extending direction of the electric wire 2 in the electric wire module 100.

  In the present embodiment, a case where the position of the start point portion 49 and the position of the end point portion 48 are the same in the circumferential direction of the protection member 3 will be described. When the position of the start point 49 and the position of the end point 48 are different in the circumferential direction of the protection member 3, the start point 49 may be set closer to the other end edge 5 in the circumferential direction of the protection member 3. preferable.

  In the present embodiment, the one end edge 4 includes a start point portion 49, a protruding portion 42, and an end point portion 48. Further, in the present embodiment, the projecting portion 42 is the most projecting portion 43 that is the most projecting portion of the projecting portion 42 in the circumferential direction, and the middle projecting portion 44 that is a portion that gradually projects toward the most projecting portion 43. , Including.

  Further, in the present embodiment, at the other end edge 5, the end surface is configured as a plane along the axial direction of the hollow portion 30. That is, the contour of the other end edge 5 is formed in a straight line. In addition, the case where the outline of the other edge 5 is a shape other than a linear shape, that is, a curved shape is also conceivable. Details will be described later.

  It is conceivable that the protective member 3 is a resin member, for example.

<Wire module: Protection member (protrusion)>
The protruding portion 42 is a portion of the one end edge 4 that is present on the opposite side to the other end edge 5 side of the starting point portion 49 in the circumferential direction of the protective member 3. Here, in the present embodiment, the start point portion 49 and the end point portion 48 are provided at the same position in the circumferential direction of the protection member 3. As shown in FIGS. 1 and 2, in this embodiment, all the portions of the one end edge 4 except the start point 49 and the end point 48 are in the other end edge of the start point 49 in the circumferential direction of the protective member 3. This is an example in the case of forming the protrusion 42 on the opposite side to the 5 side.

  In the present embodiment, the projecting portion 42 may include a midway projecting portion 44 extending from the start point portion 49 toward the most projecting portion 43 and a midway projecting portion 44 extending from the most projecting portion 43 toward the end point portion 48. It is shown. Hereinafter, if necessary, the intermediate protrusion 44 extending from the start point 49 toward the most protruding part 43 is provided as the intermediate protrusion 441, and the intermediate protrusion 44 extending from the most protruding part 43 toward the end point 48 is provided as the intermediate protrusion 442. They are distinguished from each other.

  The midway protruding portion 44 is a portion that gradually protrudes toward the most protruding portion 43. Here, gradually projecting toward the most projecting portion 43 means approaching from the start point 49 side toward the most projecting portion 43 side in the circumferential direction as it goes toward the most projecting portion 43 side along the axial direction. .

  That is, the midway protruding portion 44 is inclined in the circumferential direction. Here, when the protection member 3 is viewed from the side, it is considered that the midway protruding portion 44 is a linear or curved portion that intersects the axial direction of the hollow portion 30. In the present embodiment, the midway protruding portion 44 includes an edge that linearly intersects the axial direction of the hollow portion 30 when viewed from the side of the protective member 3.

  And in this embodiment, the protrusion part 42 is the middle protrusion part 441 which protrudes gradually toward the most protrusion part 43 from the start point part 49 side, and the middle part which protrudes gradually toward the most protrusion part 43 from the end point part 48 side. A protrusion 442. The midway protruding portion 441 and the midway protruding portion 442 intersect and are connected at one point. That is, the midway protruding portion 441 and the midway protruding portion 442 are connected at an angle.

  As shown in FIG. 2, in the present embodiment, the end surface of the midway protruding portion 44 is configured to be flat. This is because the midway protruding portion 44 intersects the axial direction of the hollow portion 30 linearly when viewed from the side of the protective member 3. In addition, the case where the end surface of the middle protrusion part 44 is comprised by the curved surface is also considered. In this case, it is conceivable that the midway protruding portion 44 intersects the curve of the axial direction of the hollow portion 30 when viewed from the side of the protective member 3. Details will be described later.

  In the present embodiment, a portion where the midway protruding portion 441 and the midway protruding portion 442 intersect forms the most protruding portion 43. That is, in the present embodiment, the most projecting portion 43 is provided at both end portions in the axial direction, that is, at an intermediate portion between one end portion (start point portion 49) and the other end portion (end point portion 48). ing.

  As shown in FIGS. 1 and 7, in the present embodiment, the dimension from the most projecting portion 43 to the start point portion 49 and the portion from the most projecting portion 43 to the end point portion 48 are the same. The position of the most protruding portion 43 is set. That is, the most projecting portion 43 is provided in the middle of the protection member 3 in the axial direction of the hollow portion 30. Note that the position of the most protruding portion 43 may be a position other than the center of the protection member 3.

  The most protruding portion 43 is a distance from the other end edge 5 in the circumferential direction of the protective member 3 of the protruding portion 42 in the protective member 3 in a state where the one side edge portion 41 and the other side edge portion 51 are formed. Is the largest part.

  As described above, in the present embodiment, the most projecting portion 43 does not have a width in the axial direction of the hollow portion 30. This is because the most projecting portion 43 is an intersection of the midway projecting portion 441 and the midway projecting portion 442. It is also conceivable that the most protruding portion 43 has a width in the axial direction of the hollow portion 30. Details will be described later.

<Wire module: Electric wire>
In this embodiment, it is possible that the electric wire 2 contains an insulated wire provided with a core wire and the insulation coating which covers the circumference | surroundings of a core wire, for example. In this case, the core wire may be a member whose main component is a metal such as copper or aluminum. The insulating coating may be a synthetic resin member mainly composed of polyethylene or vinyl chloride, for example.

  Moreover, in the electric wire module 100, the case where the electric wire 2 contains a some insulated wire or the case where one insulated wire is contained is considered.

  In the present embodiment, the electric wire 2 includes a first-in wire 21 and a last-in wire 22. Note that the first-in wire 21 may include one insulated wire or a plurality of insulated wires. Similarly, the last-inserted electric wire 22 may include one insulated wire or a plurality of insulated wires.

  For example, it is conceivable that the first-in wire 21 is a wire through which a relatively large current flows compared to the last-in wire 22. In this case, the number of insulated wires included in the first-in wire 21 is larger than the number of insulated wires included in the last-in wire 22, or the diameter of the insulated wire included in the first-in wire 21 is included in the last-in wire 22. It is conceivable that it is larger than the diameter of the insulated wire. Moreover, it is conceivable that the last-inserted electric wire 22 is an electric wire accommodated in the protective member 3 when, for example, a new circuit needs to be added.

<Electric wire module: accommodation work of electric wire>
Next, an example of the electric wire accommodation work in the electric wire module 100 of this embodiment is demonstrated, referring FIGS. In addition, in the following description, the case where the post-insertion electric wire 22 is further accommodated in the protection member 3 from the state in which the pre-insertion electric wire 21 is accommodated in the protection member 3 is demonstrated.

  First, as shown in FIG. 3, the most protruding portion 43 of the one end edge 4 of the protection member 3 is separated from the other end edge portion 51, and a gap is formed between the one end edge 4 and the other end edge portion 51. make. Here, in the present embodiment, the most protruding portion 43 is a portion where two midway protruding portions 44 intersect. For this reason, the comparatively narrow area | region in the axial center direction of the hollow part 30 of the one end edge 4 is separated from the other side edge part 51. FIG. In the state where the most projecting portion 43 is separated from the other end edge portion 51, a portion other than the most projecting portion 43 on the one end edge 4, for example, a part of the midway projecting portion 44, a start point portion 49 or an end point portion 48. However, it may be in contact with the other end 51.

  And in the state where the most protruding part 43 was separated from the other side edge part 51, as shown in FIGS. 3 to 5, the newly inserted electric wire 22 is placed between the most protruding part 43 and the other side edge part 51. Is provided. At this time, as shown in FIG. 4, in the place of the most protruding portion 43, the newly inserted wire 22 is sandwiched between both the most protruding portion 43 and the other end edge portion 51.

  On the other hand, for example, at the location of the starting point portion 49, as shown in FIG. 5, the other end edge portion 51 is present on one side of the post-insertion electric wire 22, but the post-insertion electric wire is provided on the other side. There is nothing to cover 22. That is, at the position of the starting point portion 49, a portion on the opposite side to the other side edge portion 51 side of the post-insertion electric wire 22 is exposed.

  In the present embodiment, the protection member 3 is rotated along the circumferential direction of the protection member 3 with the post-insertion electric wire 22 interposed between the most protruding portion 43 and the other end edge portion 51. Here, the protective member 3 has a structure in which the one side edge 41 overlaps the other side edge 51 in the natural state. For this reason, as the protective member 3 rotates, the late-insertion electric wire 22 that is interposed between the most protruding portion 43 and the other-side end edge portion 51 moves to the other end edge 5 side.

  Moreover, in the operation | work which rotates the protection member 3, as FIG. 6 shows, it is also considered that the newly inserted electric wire 22 contacts parts other than the most protrusion part 43 of the one edge 4. As shown in FIG. Here, in the present embodiment, the protection member 3 includes an intermediate projecting portion 44 that gradually projects toward the most projecting portion 43. For this reason, even if the late-inserted electric wire 22 contacts the midway protruding portion 44 at the one end edge 4, the late-inserted electric wire 22 is not caught by the midway protruding portion 44, and the protective member 3 is smoothly hollow with the rotation of the protective member 3. Guided into section 30.

  Therefore, the newly inserted electric wire 22 gradually moves into the hollow portion 30 as the protective member 3 rotates. As a result, a state is created in which the protective member 3 covers the periphery of the later-inserted electric wire 22. Thereby, the electric wire module 100 of this embodiment provided with the electric wire 2 including the first-in wire 21 and the last-in wire 22 and the protection member 3 can be obtained.

<Wire module>
In the electric wire module 100, an electric wire (in this example, the last inserted electric wire 22) is sandwiched between the protruding portion 42 (the most protruding portion 43 in this example) of the one end edge 4 and the other end edge portion 51, and in this state By rotating the protection member 3 in the circumferential direction, it is possible to make a state where the electric wire is inserted into the hollow portion 30 of the protection member 3. For this reason, in this embodiment, one end edge 4 is separated from the other side end edge portion 51 to create a state in which the protective member 3 is opened, and the electric wire is connected while the protective member 3 is kept open. Accommodating is unnecessary. That is, it is possible to insert the electric wire into the hollow portion 30 of the protective member 3 relatively easily as compared with the conventional complicated electric wire housing operation. That is, the protection member 3 can be easily attached with the electric wire. For this reason, it can suppress that the operation | work which attaches the protection member 3 to an electric wire becomes complicated, for example, when the attachment object area | region of the protection member 3 is comparatively long.

  In the present embodiment, the protection member 3 includes a midway protruding portion 44. In this case, the protection member 3 is rotated in the circumferential direction in a state where the electric wire is sandwiched between the most protruding portion 43 and the other end edge portion 51 at the one end edge 4. At this time, even when the electric wire comes into contact with the one end edge 4, the electric wire gradually becomes hollow with the rotation of the protective member 3 by the midway protruding portion 44 that gradually protrudes toward the most protruding portion 43. It is guided in 30. For this reason, in the operation | work which rotates the protection member 3 to the circumferential direction, it can suppress that an electric wire gets caught in the one end edge 4, and can improve the workability | operativity of the operation | work which accommodates an electric wire in the hollow part 30 of the protection member 3. .

  In the present embodiment, the most projecting portion 43 is provided at an intermediate portion between both end portions in the axial direction (in this example, the start point portion 49 and the end point portion 48). In this case, the electric wire sandwiched between the most projecting portion 43 of the one end edge 4 and the other end portion 51 is an intermediate projecting portion 441 extending from the most projecting portion 43 to both the start point portion 49 and the end point portion 48. , 442 are guided into the hollow portion 30 of the protective member 3. For this reason, in the operation | work which rotates the protection member 3 to the circumferential direction, it can suppress more that an electric wire is hooked on the one end edge 4, and improves the workability | operativity of the operation | work which accommodates an electric wire in the hollow part 30 of the protection member 3 more. Can do.

However, it is also conceivable that the protruding portion 42C includes a plurality of midway protruding portions 46, that is, formed in a step shape including a step.

  In the present embodiment, the non-projecting portion 45 is a portion that continues to the starting point portion 49, and its end surface is configured as a plane along the axial direction of the hollow portion 30. Therefore, the position of the non-projection part 45 and the position of the start point part 49 are the same in the circumferential direction of the protection member 3C.

  Also in this embodiment, it becomes possible to easily attach the protective member 3C with an electric wire.

<Fifth Embodiment>
Next, an electric wire module 500 according to the fifth embodiment will be described with reference to FIGS. The electric wire module 500 includes a protection member 3D that is different from the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment. FIG. 11 is a side view of an electric wire module 500 according to the fifth embodiment. FIG. 12 is a perspective view showing how the protective member 3D is manufactured. 11 and 12, the same components as those shown in FIGS. 1 to 10 are given the same reference numerals. Hereinafter, differences of the present embodiment from the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment will be described.

  The electric wire module 500 includes an electric wire 2 and a protection member 3D. Since the electric wire 2 has the same structure as that of the first embodiment, the description thereof is omitted.

  And in protection member 3D, the other edge (other edge 5D) is a shape which follows the outline of one edge (one edge 4). Note that the one end edge 4 of the protection member 3D has the same structure as that of the first embodiment, and a description thereof will be omitted.

  In the present embodiment, the other end edge 5 </ b> D has a shape cut into the most protruding portion 43 side of the one end edge 4. That is, the other end edge 5D is the most cut part 53 that is the part that is cut most deeply toward the most protruding part 43 side, and the middle cut that is the part that is gradually cut deeper toward the most cut part 53 Including the insertion portion 54.

  The protection member 3D is obtained, for example, by making a cut along the axial direction of one cylindrical member (cylindrical member 3X) as shown in FIG. More specifically, as shown in FIG. 12, a cut 8 along the edge shape of the one end edge 4 is made in the cylindrical member 3X. In FIG. 12, the cut 8 is indicated by a virtual line (two-dot chain line).

  In the cylindrical member 3X in which the cut 8 is formed, one end edge of the portion sandwiching the cut 8 is formed in a shape protruding to the other end side. The one end edge constitutes one end edge 4 in the protection member 3D. In addition, the other edge of the portion sandwiching the cut 8 is formed in a concave shape that is deeply cut in the opposite side to the one edge 4 side. The other end edge forms the other end edge 5D.

  And the part isolate | separated by the cut | interruption 8 in the cylindrical member 3X is formed in the shape where one edge and another edge overlap with the internal stress which is going to shrink | contract. Thereby, it is possible to obtain the protective member 3D formed in a cylindrical shape in a state where the one end edge 4 overlaps the other end edge 5D.

  Also in this embodiment, it becomes possible to easily attach the protective member 3D with an electric wire.

  In the present embodiment, the other end edge 5 </ b> D has a shape along the contour of the one end edge 4. In this case, the gap that can accommodate the electric wire formed by separating the one end edge portion 41 of the protection member 3D from the other end edge portion 51 can be further increased, and the hollow portion 30 of the protection member 3D can be accommodated. The workability of the work of housing the electric wire can be improved.

<Application example>
In 1st Embodiment, the case where binding members, such as a tape, are further wound around the protection member 3 is also considered. The same applies to the second to fifth embodiments.

  In 1st Embodiment, the case where the electric wire 2 contains only the first-in wire 21 is also considered. In this case, the workability of the work of housing the first-in wire 21 in the protection member 3 can be improved. In addition, the said structure is also applicable to 2nd Embodiment-5th Embodiment.

  The protective member and the electric wire module according to the present invention can be freely combined with each of the embodiments and application examples shown above within the scope of the invention described in each claim, or each embodiment and application example. It is also possible to configure by appropriately modifying or omitting a part.
