FIG. 5 is a schematic cross-sectional view taken along line VV in FIG. In the present specification, the front view is a position as shown in FIGS. 4 and 5, that is, viewed from the extending direction of the electric wire 12 extending from the end of the protector 20.

  The electric wire module 10 according to the embodiment includes an electric wire 12, a binding member 60, and a protector 20.

  It is sufficient that at least one electric wire 12 is included. The intermediate portion of the electric wire 12 is accommodated in the main body portion 22 of the protector 20. The electric wire 12 is configured such that a covering portion is formed by extrusion coating of resin on the outer periphery of the core wire. Here, an example of an electric wire bundle in which a plurality of electric wires 12 are bundled will be described. An optical fiber or the like may be disposed along the electric wire 12 in the electric wire bundle. The electric wire 12 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 12 is arranged at a location to be arranged on the vehicle or the like. In addition, in FIGS. 1-5, the schematic form of the wire bundle is drawn.

  The binding member 60 includes a band part 62 and a band fixing part 64. The binding member 60 is a member for fixing the electric wire 12 to the protector 20. More specifically, the bundling member 60 is fixed to the band fixing portion 64 in a state where the band portion 62 is wound around the fixing portion 30 of the protector 20 and the electric wire 12, which will be described later. 12 can be fixed.

  The band part 62 is formed in a narrow strip shape longer than the outer peripheral length of the electric wire 12 to be wound. Here, the band 62 is formed so as to extend substantially linearly before being wound around the electric wire 12.

  The band fixing portion 64 is continuous with one end portion of the band portion 62. Moreover, the band fixing | fixed part 64 is formed so that the other side edge part of the band part 62 can be fixed.

  The band part 62 and the band fixing part 64 can be fixed in the following configuration, for example.

  That is, a plurality of recesses are formed on any one of the main surfaces of the band portion 62 at intervals along the longitudinal direction. In addition, an insertion hole 66 through which the band part 62 can be inserted is formed in the band fixing part 64, and a locking projection that can be locked in the recess of the band part 62 is provided on the inner peripheral surface of the insertion hole 66. . The band portion 62 and the band fixing portion 64 are fixed by selectively locking the locking protrusions of the band fixing portion 64 in the plurality of concave portions of the band portion 62 inserted through the insertion hole 66.

  Here, it is formed so that the axial direction of the insertion hole 66 and the extending direction of the band portion 62 are substantially parallel. For this reason, as shown in FIG. 4 or FIG. 5, the base end portion of the band portion 62 and the tip end portion that has passed through the insertion hole 66 are substantially parallel, and an outer guide portion 32 and an inner guide portion 36 of the protector 20 described later. Can be located between.

  However, it is not essential that the axial direction of the insertion hole 66 and the extending direction of the band portion 62 are substantially parallel. For example, it is conceivable that the axial direction of the insertion hole 66 and the extending direction of the band portion 62 are orthogonal to each other. In this case, in the state where the base end portion of the band portion 62 is located between the outer guide portion 32 and the inner guide portion 36 of the protector 20, the tip portion of the band portion 62 that has passed through the insertion hole 66 is exposed to the outside. .

  In addition, the fixing method of the band part 62 and the band fixing | fixed part 64 is not restricted above. For example, a configuration in which a plurality of concave portions are provided on both side surfaces of the band portion 62 and a locking projection that fits into the concave portion projects from the inner peripheral surface of the insertion hole 66 may be adopted.

  The protector 20 includes a main body portion 22, a fixing portion 30, and an outer guide portion 32. Furthermore, the protector 20 is provided with the cover part 50 and the inner side guide part 36 here.

  The main body portion 22 is formed so as to be able to accommodate a middle portion in the longitudinal direction of the electric wire 12. Specifically, here, the main body portion 22 includes a bottom portion 24 and a side wall portion 26.

  The bottom 24 is formed in a shape along the arrangement path of the electric wires 12. Here, the bottom portion 24 is formed in a shape that is partially bent in the same plane along the longitudinal direction thereof, that is, in a two-dimensional shape. But the bottom part 24 may be formed in the linear one-dimensional shape along the longitudinal direction, or the three-dimensional shape along a different surface.

  The side wall portion 26 is erected on the bottom portion 24. Here, the pair of side wall portions 26 is erected from the width direction end portion of the bottom portion 24 in a direction orthogonal to the width direction of the bottom portion 24. However, the standing direction of the side wall portion 26 may be a direction extending obliquely with respect to the width direction of the bottom portion 24.

  In addition, since the bottom part 24 is formed in a semi-arc shape in more detail so that the center in the width direction is recessed here, the main body part 22 is formed in a U shape in a front view. However, it is not essential that the main body portion 22 is formed in a U-shape in front view, and the main body portion 22 may be formed in a front view angle shape.

  Here, the side wall portion 26 is provided with a plurality of pairs of recesses 28 into which protrusions 52 of the lid portion 50 described later are fitted. The concave portion 28 includes a pair of extending pieces 28 a protruding outward from the side wall portion 26 in the longitudinal direction of the electric wire 12, a connecting piece 28 b connecting the pair of extending pieces 28 a, and the side wall portion 26. It is provided in the shape of an enclosed through hole. The pair of recesses 28 is also provided at the longitudinal end of the main body 22. And the extension piece 28a which is the extension piece 28a which comprises one recessed part 28 among the pair of recessed parts 28 provided in the longitudinal direction edge part of the main-body part 22, Comprising: The extension piece 28a provided in the edge part of the main-body part 22 is provided. It extends from the side wall part 26 to the bottom part 24. An outer guide portion 32 described later extends from an extending piece 28 a extending from the side wall portion 26 to the bottom portion 24.

  The fixing part 30 is provided at the end of the main body part 22. The fixing part 30 can fix the electric wire 12 by being wound around the band part 62 together with the electric wire 12.

  Specifically, the fixing portion 30 is formed in such a manner that a part along the circumferential direction of the bottom portion 24 extends in the longitudinal direction of the electric wire 12. The fixed portion 30 is provided so that the inner surface thereof is smoothly continuous with the inner surface of the bottom portion 24. Here, since the bottom portion 24 is formed in a semi-arc shape, the inner surface of the fixed portion 30 is also formed in a front view arc shape.

  Here, the fixing portion 30 is formed to have a substantially constant thickness along the longitudinal direction and the circumferential direction. But the thickness dimension of the fixing | fixed part 30 should just be set so that it may have the rigidity which does not deform | transform in the state wound around the binding member 60 with the electric wire 12. FIG. Similarly, the width dimension of the fixed portion 30 may be set so as to have rigidity so as not to be deformed when wound around the binding member 60 together with the electric wires 12.

  The outer guide portion 32 is provided at an end portion of the main body portion 22 where the fixing portion 30 is provided. The outer guide portion 32 is formed in such a manner that its inner peripheral surface is bent along at least part of the circumferential direction of the electric wire 12 so that the band portion 62 can be guided radially outward of the fixed portion 30. Yes.

  Specifically, the outer guide part 32 is formed in such a manner that a part from one side wall part 26 (extending piece 28 a located outside the side wall part 26) to the bottom part 24 extends in the longitudinal direction of the electric wire 12. Has been. At this time, the inner surface of the outer guide portion 32 is formed by a quarter of the circumference in the circumferential direction. Moreover, the outer side guide part 32 is formed so that it may have substantially constant thickness along the circumferential direction. For this reason, the outer surface of the outer side guide part 32 follows the inner surface of itself, and the outer side guide part 32 is formed in 1/4 arc shape of front view. That is, the extending direction on one end side of the outer guide portion 32 along the circumferential direction of the electric wire 12 is orthogonal to the extending direction on the other end side.

  However, it is not essential that the outer guide portion 32 is formed by a quarter of the circumference in the circumferential direction of the electric wire 12. For example, the outer guide portion 32 may be shorter than a quarter of a circle, such as being formed in the circumferential direction of the electric wire 12 for one sixth or one eighth. Further, for example, the outer guide portion 32 may be longer than a quarter of a circle, for example, formed in the circumferential direction of the electric wire 12 by a half or a third. If the peripheral length of the outer side guide part 32 is set short, the contact area of the binding member 60 and the electric wire 12 will increase, and the electric wire 12 can be fixed more firmly. In addition, when the outer guide portion 32 is set to have a long peripheral length, the amount by which the binding member 60 is guided by the outer guide portion 32 increases, and the winding operation of the binding member 60 becomes easier. In other words, when the outer guide portion 32 is formed by a quarter of the circumference in the circumferential direction of the electric wire 12, the outer guide portion 32 reduces the contact area between the electric wire 12 and the binding member 60 as much as possible and the binding member 60. The amount of guiding can be increased.

  Here, the outer surface of the outer guide portion 32 is formed so as to be partially continuous with the outer surface of the main body portion 22. For this reason, the protruding amount of the protector 20 is suppressed.

  The inner guide portion 36 is provided so as to partially face the outer guide portion 32 on the radially inner side of the outer guide portion 32.

  Specifically, the outer surface of the inner guide portion 36 is formed along the inner surface of the outer guide portion 32 in a state of being spaced from the inner surface of the outer guide portion 32 in the radial direction of the electric wire 12. Here, the distance between the outer surface of the inner guide portion 36 and the inner surface of the outer guide portion 32 along the radial direction of the electric wire 12 is equal to or larger than the thickness dimension of the band portion 62 (here, slightly more than twice). Large) is set. Thereby, the band part 62 can be inserted between the inner guide part 36 and the outer guide part 32.

  Further, here, the inner surface of the inner guide portion 36 is formed so as to be smoothly continuous with a surface obtained by extending the inner surface of the fixed portion 30 along the circumferential direction of the electric wire 12. Accordingly, when the binding member 60 is wound around the electric wire 12 and the fixing portion 30 in a state where the electric wire 12 is in contact with the fixing portion 30, the inner guide portion 36 is also in contact with the electric wire 12 and is bound around the electric wire 12. The member 60 is wound. That is, the inner side guide part 36 bears a part of force concerning the fixing | fixed part 30, and assists the fixing | fixed part 30 fixing the electric wire 12. FIG.

  In addition, here, the end in the circumferential direction of the inner guide portion 36 and the end opposite to the fixed portion 30 side is along the circumferential end of the outer guide portion 32 and the height direction of the side wall portion 26. Are set to the same position. Thereby, the surface in which the opening which can penetrate the band part 62 was formed in the edge part of the inner side guide part 36 and the edge part of the outer side guide part 32 is comprised. As shown in FIG. 4 or 5, the band fixing portion 64 is positioned on this surface, so that the positional deviation of the band fixing portion 64 can be suppressed. At this time, if the distance between the inner guide portion 36 and the outer guide portion 32 is set to be twice or more the thickness of the band portion 62, the tip of the band portion 62 fixed by the band fixing portion 64 is also the inner guide portion. 36 and the outer guide portion 32 can be accommodated. Thereby, it can suppress that the band fixing | fixed part 64 protrudes outside.

  Here, an outer wall portion 40 that connects the fixed portion 30, the outer guide portion 32, and the inner guide portion 36 is provided at the outer edge in the longitudinal direction of the electric wire 12. Thereby, the intensity | strength of the fixing | fixed part 30, the outer side guide part 32, and the inner side guide part 36 can be raised, respectively. Further, the distance between the main body portion 22 and the outer wall portion 40 is set to be equal to or larger than the width dimension of the band portion 62 (here, slightly larger). Thereby, it can suppress that the band part 62 inserted between the outer side guide part 32 and the inner side guide part 36 from opening is displaced along the longitudinal direction of the electric wire 12. FIG.

  Here, the main body 22 is formed by a method of pulling a pair of molds into one and the other, so-called top and bottom punching. That is, the fixed portion 30, the outer guide portion 32, and the inner guide portion 36 are also formed by removing the top and bottom. A configuration that enables the fixing portion 30, the outer guide portion 32, and the inner guide portion 36 to be formed by vertically removing will be described below.

  That is, the fixed portion 30 and the outer guide portion 32 are formed at positions apart from each other when viewed from a certain direction. Further, in the portion where the inner guide portion 36 and the outer guide portion 32 overlap each other when viewed from the one direction, the inner guide portion 36 is provided with a gap 38 along the circumferential direction of the electric wire 12, and the outer guide portion 32. Among them, the width dimension of the portion facing the gap 38 is set to be equal to or smaller than the width of the gap 38. Thereby, the main-body part 22 can be extracted up and down along the said one direction.

  More specifically, here, the direction perpendicular to the width direction of the bottom portion 24, that is, the direction along the extending direction of the side wall portion 26 is set to be a direction in which the main body portion 22 is vertically removed. Hereinafter, the extending direction of the side wall portion 26 is referred to as the up-down direction.

  That is, here, the fixed portion 30 and the outer guide portion 32 are formed at positions separated from each other so as not to overlap each other when viewed in the vertical direction. Further, here, in the portion where the inner guide portion 36 and the outer guide portion 32 overlap each other when viewed in the vertical direction, the inner guide portion 36 is provided with a gap 38 along the circumferential direction of the electric wire 12, and the outer guide portion. The width dimension of the portion of 32 facing the gap 38 is set to be equal to or smaller than the width of the gap 38.

  More specifically, a gap 38 along the circumferential direction is provided in the middle portion of the inner guide portion 36 in the longitudinal direction of the electric wire 12. However, a gap 38 is provided at one end of the inner guide portion 36 in the longitudinal direction of the electric wire 12, that is, at a connection portion between the inner guide portion 36 and the main body portion 22 or a connection portion between the inner guide portion 36 and the outer wall portion 40. May be provided.

  The width of the portion of the outer guide portion 32 that faces the gap 38 when viewed from the top (hereinafter referred to as the facing portion 33) is equal to or smaller than the width of the gap 38 (here, about half the width of the gap 38). ) Is set. From another viewpoint, the through-hole 34 is formed in a portion of the outer guide portion 32 that overlaps with the inner guide portion 36 remaining after the gap 38 is provided, when viewed from the vertical direction. That is, here, through holes 34 are formed in a part of the outer guide portion 32 that is continuous with the main body portion 22 and a portion that is continuous with the outer wall portion 40. Thus, the outer guide portion 32 and the inner guide portion 36 are formed so as not to overlap each other when viewed in the vertical direction.

  At this time, the width of the facing portion 33 may be set to have sufficient rigidity to guide the band portion 62. The width dimension of the gap 38 may be set to be equal to or larger than the width dimension of the facing portion 33. At this time, the width dimension of the gap 38 is preferably set smaller than the width dimension of the band portion 62. If the width dimension of the gap 38 is set to be smaller than the width dimension of the band section 62, the band section 62 is prevented from falling off the gap 38 when the band section 62 is wound around the outer periphery of the inner guide section 36. can do.

  Here, the inner guide portion 36 and the fixed portion 30 are formed at intervals in the circumferential direction. In this case, the outer surface and the inner surface of the inner guide portion 36 are formed so as to be smoothly continuous with a surface obtained by extending the outer surface and the inner surface of the fixing portion 30 along the circumferential direction of the electric wire 12. The inner guide portion 36 and the fixed portion 30 are formed in a shape that extends from the main body portion 22 and is formed in a shape in which an extension piece formed in a front view arc shape is separated by a slit formed in a middle portion in the circumferential direction. Yes.

  The distance between the inner guide part 36 and the fixed part 30 is set to be larger than the distance between the outer guide part 32 and the fixed part 30 when viewed in the vertical direction. For this reason, the outer side guide part 32 is formed so that it may be connected integrally from the main-body part 22 to the outer wall part 40 in the edge part by the side of the fixing | fixed part 30. FIG. Thereby, the intensity | strength of the outer side guide part 32 can be increased.

  The lid 50 is provided so as to close the opening of the main body 22. Specifically, the lid portion 50 is formed in a shape along the bottom portion 24, and the dimension in the width direction is set to be approximately the same as the interval between the pair of side wall portions 26. The lid 50 is provided with a plurality of pairs of protrusions 52 at intervals along the extending direction. The pair of protrusions 52 are provided so as to protrude from the both ends in the width direction of the lid 50 toward the bottom 24. By fitting the projection 52 into the concave portion 28 of the main body 22 described above, the lid 50 is fixed to the main body 22.

  But it is not essential that the protector 20 is provided with the cover part 50, and it is possible that the cover part 50 is not provided. Even when the protector 20 includes the lid portion 50, it is not essential that the lid portion 50 is provided with the projection 52 and the main body portion 22 is formed with the concave portion 28 into which the projection 52 is fitted. The lid 50 and the main body 22 may be fixed by, for example, tape winding.

<Operation>
Next, the operation of housing the electric wire 12 in the protector 20 and fixing the protector 20 and the electric wire 12 by the binding member 60 will be described.

  First, the lid part 50 of the protector 20 is opened, and the longitudinal direction intermediate part of the electric wire 12 is accommodated in the main body part 22. At this time, the protector 20 is positioned at a predetermined position with respect to the longitudinal direction of the electric wire 12.

  When the electric wire 12 is accommodated in the main body portion 22, the band portion 62 of the binding member 60 is inserted between the outer guide portion 32 and the inner guide portion 36 from the tip. At this time, the band portion 62 extends straight in the longitudinal direction thereof, and the inner peripheral surface of the outer guide portion 32 is bent in the circumferential direction of the electric wire 12. The part eventually comes into contact with the inner peripheral surface of the outer guide part 32. Then, when the operator further inserts the band part 62 in a state where the front end edge of the band part 62 is in contact with the inner peripheral surface of the outer guide part 32, the front end edge of the band part 62 becomes the outer guide part. It moves automatically in the circumferential direction of the electric wire 12 along the inner peripheral surface of 32, and eventually comes out of the fixed portion 30 along the width direction of the bottom portion 24 from the radially outer side of the fixed portion 30.

  The length of the portion of the band portion 62 that is located outside the fixed portion 30 when viewed from the top and bottom is such that it can be wound around the entire remaining portion of the wire 12 (here, the circumferential length of the wire 12). Over about three quarters) until the band fixing part 64 reaches the end of the outer guide part 32, the operator winds the band part 62 around the electric wire 12, and the tip is attached to the band fixing part. The band portion 62 is fixed to the band fixing portion 64 through the 64 insertion holes 66. At this time, it is preferable to leave a margin to the extent that the band fixing portion 64 can be moved in the circumferential direction of the electric wire 12.

  Finally, the band fixing part 64 is brought into contact with the end surfaces of the outer guide part 32 and the inner guide part 36, and the band fixing part 64 is tightened so that the band fixing part 64 is not displaced. Is fixed.

  According to the electric wire module 10 and the protector 20 according to the embodiment, the band portion 62 is provided at the end portion of the main body portion 22 where the fixing portion 30 is provided, so that the band portion 62 can be guided radially outward of the fixing portion 30. In order to provide the outer guide portion 32 formed so that the inner peripheral surface thereof is bent along at least a part of the circumferential direction of the electric wire 12, the band portion 62 is arranged along the inner peripheral surface of the outer guide portion 32. By winding, the band part 62 can be easily wound and fixed around the electric wire 12.

  Further, since the inner guide portion 36 is further provided so as to face the outer guide portion 32 on the radially inner side of the outer guide portion 32, the tip of the band portion 62 is formed between the outer guide portion 32 and the inner guide portion 36. When intervening, the band part 62 becomes difficult to move in the radial direction, so that the movement of the band part 62 in the circumferential direction is stabilized, and the band part 62 can be easily wound around the electric wire 12.

  Further, the fixed portion 30 and the outer guide portion 32 are formed at positions separated from each other when viewed in the vertical direction, and the inner guide portion 36 and the outer guide portion 32 overlap with each other when viewed from the vertical direction. The inner guide portion 36 is provided with a gap 38 along the circumferential direction of the electric wire 12, and the width dimension of the portion facing the gap 38 of the outer guide portion 32 is set to be equal to or smaller than the width of the gap 38. When the protector 20 is manufactured using the above, the protector 20 can be easily manufactured by removing the pair of molds in the vertical direction.

  Further, since the outer guide portion 32 is formed by a quarter of the circumference in the circumferential direction, the band portion 62 is automatically placed on the outer guide portion 32 to automatically make a quarter turn with respect to the electric wire 12. By being able to wind, the band part 62 can be easily wound around the electric wire 12.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
