  However, when positioning the exterior member with respect to the electric wire using the technique described in Patent Literature 1 or Patent Literature 2, a positioning member other than the electric wire is necessary.

  Then, an object of this invention is to provide the technique which can aim at positioning with an electric wire and an exterior member using an electric wire.

  In order to solve the above problems, an electric wire with an exterior member according to a first aspect includes an electric wire and a main body portion formed so as to be capable of being wound around the electric wire, and the main body portion is formed by being wound around the electric wire. A through hole is formed in the main body, and the electric wire is inserted through the through hole.

  An electric wire with an exterior member according to a second aspect is an electric wire with an exterior member according to the first aspect, wherein a plurality of the through holes are formed in the main body, and the electric wires are inserted into the plurality of through holes. Yes.

  The electric wire with an exterior member according to the third aspect is an electric wire with an exterior member according to the second aspect, and includes a plurality of wires in a direction inclined with respect to a direction connecting both ends of the exterior member wound around the electric wire. The through holes are arranged.

  The electric wire with an exterior member according to the fourth aspect is an electric wire with an exterior member according to any one of the first to third aspects, and includes a plurality of the electric wires, and the plurality of electric wires are connected to the through hole. And a first electric wire and a second electric wire inserted in opposite directions.

  An electric wire with an exterior member according to a fifth aspect is an electric wire with an exterior member according to any one of the first to fourth aspects, comprising a plurality of the electric wires, wherein a part of the plurality of electric wires is the It is inserted through the through hole.

  According to the first to fifth aspects, since the electric wire is inserted through the through-hole, when the main body portion is likely to be displaced in the extending direction of the electric wire with respect to the electric wire, the peripheral edge of the through-hole comes into contact with the electric wire. . Thereby, when a main-body part becomes difficult to position-shift in the extension direction of an electric wire with respect to an electric wire, positioning of an electric wire and an exterior member can be aimed at using an electric wire.

  In particular, according to the second aspect, since the electric wire is inserted into the plurality of through holes, when the main body portion is likely to be displaced in the extending direction of the electric wire with respect to the electric wire, the peripheral edge of each through hole and the electric wire are Abut. Thereby, the effect which becomes difficult to position-shift a main-body part in the extension direction of an electric wire with respect to an electric wire increases.

  In particular, according to the third aspect, since the plurality of through holes are arranged in a direction inclined with respect to the direction connecting the both ends of the exterior member wound around the electric wire, the direction in which the electric wire extends from the end of the exterior member; The direction in which the plurality of through holes are arranged intersects each other. Thereby, the effect that an exterior member becomes difficult to shift in the direction where an electric wire extends from the end of an exterior member increases.

  In particular, according to the fourth aspect, since the plurality of electric wires include the first electric wire and the second electric wire inserted in opposite directions with respect to the through hole, the periphery of the through hole is defined as the first electric wire and the second electric wire. As a result, the effect of making the exterior member difficult to shift is enhanced.

  Particularly, according to the fifth aspect, a plurality of electric wires are provided, and some of the plurality of electric wires are inserted through the through holes. Therefore, since there is an electric wire that is not inserted through the through hole, it is easier to manufacture the electric wire with the exterior member than when all the electric wires are passed through the through hole.

{Embodiment}
Hereinafter, the electric wire with an exterior member according to the embodiment will be described. Drawing 1 is a top view showing electric wire 10 with an exterior member concerning an embodiment. Drawing 2 is a side view showing electric wire 10 with an exterior member concerning an embodiment. FIG. 3 is a plan view showing the exterior member 30 according to the embodiment. FIG. 4 is an explanatory diagram illustrating a state in which the electric wire 20 is disposed on the exterior member 30 according to the embodiment. FIG. 5 is a cross-sectional view taken along line VV in FIG.

  The exterior member-attached electric wire 10 includes an electric wire 20 and an exterior member 30.

  The electric wire 20 is configured such that a covering portion is formed by extrusion coating or the like of an insulating resin on the outer periphery of a conductive core wire. The core wire is formed of, for example, a material mainly composed of copper or aluminum. The electric wire 20 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 20 is arranged at a location to be arranged on the vehicle or the like.

  The exterior member 30 includes a main body 32 formed so as to be wound around the electric wire 20. Here, the main body 32 is formed in a sheet shape using a resin or the like as a material. A main body 32 is wound around the electric wire 20 to form an exterior member 30. A through hole 38 is formed in the main body portion 32. The electric wire 20 is inserted through the through hole 38.

  Here, the main body 32 is described as being formed in a rectangular sheet shape. Below, the extending direction of one edge part 33a is called the 1st direction D1 among two pairs of edge parts 33a and 33b of rectangular sheet form, and the extending direction of the other edge part 33b is called 2nd direction D2.

  The exterior member-attached electric wire 10 only needs to include at least one electric wire 20. As shown in FIG. 4, the exterior member-attached electric wire 10 includes a plurality of electric wires 20 here. Some of the positioning and fixing wires 22 among the plurality of wires 20 are inserted into through holes 38 provided in the exterior member 30. And the main body part 32 is wound around the other winding object electric wire 28 of the some electric wire 20 in the state which is not penetrated by the through-hole 38. As shown in FIG. The plurality of electric wires 20 are disposed along the first direction D <b> 1 with respect to the main body portion 32. The main body 32 is wound around the plurality of electric wires 20 so that the direction connecting the winding start portion 36 and the winding end portion 37 coincides with the second direction D2. However, there is a case where the winding target electric wire 28 does not exist and all the electric wires 20 are inserted through the through holes 38.

  A plurality of through holes 38 (five in the example shown in FIG. 4) are formed in the main body 32. The positioning and fixing wire 22 is inserted into the five through holes 38. Here, five through holes 38 are formed in a line. Here, the five through holes 38 are formed side by side along the first direction D1. Then, among the five through holes 38 arranged in a row, the positioning is fixed in order from the through hole 38a located at one end along the parallel direction (here, the first direction D1) to the through hole 38 located at the other end. An electric wire 22 is inserted. Here, the five through holes 38 are arranged in a straight line along the parallel direction, but the arrangement of the five through holes 38 is not limited to this. A part of the five through holes 38 may be shifted in the second direction D2, and the five through holes 38 may be formed so as to be arranged in a zigzag shape along the parallel direction, for example.

  Here, the through hole 38 is formed in a circular shape, but this is not essential. The through hole 38 may be formed in, for example, a square shape or a shape in which cuts are formed radially from one point. The shape and size of the through hole 38 may be set as appropriate. Moreover, although the five through-holes 38 are formed in the same shape, this is not essential. The five through holes 38 may be formed in different shapes or sizes.

  The positioning and fixing electric wire 22 includes a first electric wire 23 and a second electric wire 24 that are inserted in opposite directions with respect to the through hole 38. In the example shown in FIG. 4, the first electric wire 23 is inserted from one side along the first direction D1 and the one main surface 34 side of the main body 32 with respect to the through hole 38a, and the other along the first direction D1. Side and the other main surface 35 side. On the other hand, the second electric wire 24 is inserted into the through hole 38a from one side along the first direction D1 and the other main surface 35 side of the main body 32, and the other side and one along the first direction D1. It has come out to the main surface 34 side. Similarly, the 1st electric wire 23 and the 2nd electric wire 24 are inserted in the mutually reverse direction also with respect to the four through-holes 38 located in the other end side along the parallel direction from the through-hole 38a. The operation of inserting the positioning and fixing wire 22 into the through hole 38 may be performed at a stage before the end of the positioning and fixing wire 22 is connected to a connector or the like. In the example shown in FIG. 4, each of the first electric wires 23 and the second electric wires 24 is one, but at least one of the first electric wires 23 and the second electric wires 24 is composed of a plurality of electric wires 20. May be.

  The five through holes 38 are formed at positions close to one of the pair of edge portions 33a along the second direction D2 in the main body portion 32. And the length dimension of the part between the through-hole 38 and the other of a pair of edge part 33a along the 2nd direction D2 among the main-body parts 32 is the circumference | surroundings of the diameter (diameter of electric wire bundle) of the winding object electric wire 28. It is formed larger than the dimension in the direction. Accordingly, when the main body 32 is wound around the electric wire 20 with the one close to the through hole 38 among the pair of edge portions 33 a as the winding start portion 36, the through hole 38 and the positioning and fixing electric wire 22 are connected to the main body 32. Covered by the winding end portion 37. For this reason, the positioning and fixing wire 22 is more reliably protected. Further, as shown in FIG. 2, the positioning and fixing are performed by winding the main body 32 around the electric wire 20 so that the winding start portion 36 including the positioning and fixing electric wire 22 is in close contact with the winding target electric wire 28 and the winding end portion 37. It becomes difficult for the electric wire 22 to come out of the through hole 38.

  However, the positions where the five through holes 38 are formed are not limited to the above, and may be formed closer to the center. Further, it is not essential that the positioning and fixing wire 22 is covered with the winding end portion 37, and the positioning and fixing wire 22 may be exposed without being covered with the winding end portion 37.

  The winding end portion 37 of the main body portion 32 is preferably fastened to the main body portion 32 or the electric wire 20 located on the inner peripheral side of the winding end portion 37. As a method of fastening the winding end portion 37, a method such as double-sided tape, adhesive, or welding can be employed. Here, the winding end portion 37 is fastened to the outer surface of the body portion 32 (winding start portion 36) on the inner peripheral side by a double-sided tape 50 as shown in FIG.

  According to such an electric wire 10 with an exterior member, since the positioning and fixing wire 22 is inserted into the through hole 38, the main body portion 32 is positioned in the extending direction of the positioning and fixing wire 22 with respect to the positioning and fixing wire 22. When it is likely to shift, the peripheral edge of the through hole 38 comes into contact with the positioning fixing wire 22. Thereby, positioning of the electric wire 20 and the exterior member 30 using the electric wire 20 is facilitated by making the main body portion 32 less likely to be displaced in the extending direction of the positioning and fixing electric wire 22 with respect to the positioning and fixing electric wire 22. Can do. At this time, since a binding material such as an adhesive tape wound around the electric wire 20 and the exterior member 30 can be omitted, it is possible to reduce the product weight, the member cost, and the like. Further, as compared with the case where the adhesive tape is wound and bound, the work related to the insertion of the positioning and fixing wire 22 is simplified because the adhesive surface need not be considered. Thereby, it becomes easy to respond to automation of manufacture of the electric wire 10 with an exterior member.

  Further, since the positioning and fixing electric wires 22 are sequentially inserted into the plurality of through holes 38, each of the main body portions 32 is likely to be displaced in the extending direction of the positioning and fixing electric wires 22 with respect to the positioning and fixing electric wires 22. The peripheral edge of the through-hole 38 and the positioning fixing wire 22 abut. Thereby, the effect that the main-body part 32 becomes difficult to position-shift in the extending direction of the positioning fixing electric wire 22 with respect to the positioning fixing electric wire 22 increases.

  In addition, since the positioning and fixing electric wire 22 includes the first electric wire 23 and the second electric wire 24 that are inserted in opposite directions with respect to the through hole 38, the periphery of the through hole 38 is connected to the first electric wire 23 and the second electric wire. As a result of the occurrence of a portion sandwiched by 24, the effect of making it difficult for the exterior member 30 to be displaced increases.

  A plurality of electric wires 20 are provided, and some of the positioning and fixing electric wires 22 among the plural electric wires 20 are inserted into the through holes 38. Therefore, since there is the winding target electric wire 28 that is not inserted through the through hole 38, it is easier to manufacture the electric wire 10 with the exterior member than when all the electric wires 20 are passed through the through hole 38.

{Modifications}
The modification of the electric wire 10 with an exterior member which concerns on embodiment is demonstrated. In the description of this modification, the same components as those described in the embodiment are denoted by the same reference numerals and description thereof is omitted.

  First, a modified example of the exterior member 30 will be described. FIG. 6 is a plan view showing an exterior member 130 according to a first modification. FIG. 7 is an explanatory diagram illustrating a state in which the electric wire 20 is disposed on the exterior member 130 according to the first modification.

  The exterior member 130 according to the first modified example is different from the exterior member 30 in that the through holes 138 are arranged with respect to the main body portion 32. In the exterior member 130, the plurality of through holes 138 are arranged in a direction inclined with respect to a direction (here, the first direction D1) connecting both ends of the exterior member 130 wound around the electric wire 20. In the example shown in FIG. 6, the plurality of through holes 138 are formed so as to be aligned along the direction intersecting the first direction D1 and the second direction D2 with respect to the main body portion 32. However, the plurality of through holes 138 may be formed so as to be aligned with the main body portion 32 along the second direction D2, that is, along the direction connecting the winding start portion 36 and the winding end portion 37.

  When the positioning and fixing wires 22 are sequentially inserted into the through holes 138 arranged in this manner from the through holes 138 on one end side in the parallel direction, the result is as shown in FIG. In the example shown in FIG. 7, the first electric wire 23 and the second electric wire 24 are inserted through the through hole 138. In this state, when the exterior member 130 with the positioning and fixing wire 22 is wound around the winding target wire 28, the portion of the positioning and fixing wire 22 inserted through the through hole 138 is the winding target wire. 28 is wound around. In particular, in the example shown in FIG. 7, the positioning and fixing electric wire 22 is spirally wound around the winding target electric wire 28.

  When such an exterior member 130 is used, a plurality of through holes 138 are arranged in a direction inclined with respect to a direction connecting both ends of the exterior member 130 wound around the electric wire 20. And the direction in which the plurality of through holes 138 are arranged cross each other. Thereby, the effect that the exterior member 130 becomes difficult to shift in the direction in which the electric wire 20 extends from the end of the exterior member 130 is enhanced.

  Next, the exterior member according to the second modification will be described. FIG. 8 is a plan view showing an exterior member 230 according to a second modification.

  The exterior member 230 according to the second modification differs from the exterior member 30 according to the embodiment in that a slit 39 that connects the peripheral edge of the through hole 38 and the edge portion 33a of the main body portion 32 is formed. The slit 39 is formed so as to connect the edge 33 a close to the through hole 38 in the edge 33 a of the main body 32 and the periphery of the through hole 38. In the example shown in FIG. 8, the slit 39 is formed in a straight line, but the present invention is not limited to this. For example, the slit may be formed in a curved line shape or a bent line shape.

  When such an exterior member 30 is used, an intermediate portion of the positioning and fixing wire 22 can be disposed in the through hole 38 through the slit 39. Thereby, it is not necessary to pass the positioning and fixing wire 22 from the end portion through the through hole 38, and the positioning work of the positioning and fixing wire 22 with respect to the main body portion 32 is facilitated.

  In addition, in the embodiment, the main body 32 of the exterior member 30 has been described as being formed in a sheet shape, but this is not essential. It is also conceivable that the main body is formed in a shape in which at least a part along the second direction D2 is curved.

  Next, a modified example of how the positioning fixing electric wire 22 is passed through the through hole 38 in the exterior member 30 will be described. FIG. 9 is an explanatory view showing a modification of how to pass the positioning and fixing wire 22 into the through hole 38. FIG. 10 is an explanatory view showing another modified example of how to pass the positioning and fixing wire 22 through the through hole 38.

  In the embodiment, one positioning and fixing electric wire 22 is inserted in the opposite direction with respect to the adjacent through hole 38, but this is not essential. As shown in FIG. 9, one positioning and fixing wire 22 may be inserted in the same direction with respect to the adjacent through hole 38. Specifically, in the example shown in FIG. 9, after the positioning and fixing electric wire 22 is inserted into the through hole 38 a from the one main surface 34 side and comes out to the other main surface 35 side, the edge portion 33 a is reached and then the edge portion is reached. Crosses 33a and again extends to the one main surface 34 side. Then, after passing again from the one main surface 34 side to the through hole 38b adjacent to the through hole 38a and coming out to the other main surface 35 side, the edge 33a is reached, and then across the edge 33a, the one main surface 34 again. Extends to the side. Thereafter, by repeating this, the positioning and fixing wire 22 extends outward from the main body portion 32 from the through hole 38 located on the other end side.

  In the embodiment, one positioning and fixing wire 22 is inserted in order without returning along the direction in which the through holes 38 are arranged (here, the first direction D1), but this is not essential. As shown in FIG. 10, there may be a portion where the positioning and fixing electric wire 22 returns along the direction in which the through holes 38 are arranged (here, the first direction D1). Specifically, in the example shown in FIG. 10, after the positioning and fixing wire 22 is inserted into the through hole 38 a from the other main surface 35 side and pulled out to the one main surface 34 side, it returns to the edge portion 33 b and then returns to the edge portion 33 b. Is again extended to the other main surface 35 side. Then, after passing through the through hole 38b adjacent to the through hole 38a from the other main surface 35 side and coming out to the one main surface 34 side, it returns to the through hole 38a and then passes through the through hole 38a from the one main surface 34 side. Is extended to the other main surface 35 side. Thereafter, by repeating this, the positioning and fixing wire 22 extends outward from the main body portion 32 from the through hole 38 located on the other end side.

  Further, as shown in FIG. 11, it is conceivable that the positioning fixing electric wire 22 is provided with a retaining portion 25 larger than the through hole 38 in a part of the positioning fixing electric wire 22. In the example shown in FIG. 11, the retaining portions 25 are formed at the base portions of the positioning and fixing electric wires 22 extending from the through holes 38 located at both ends to the outside of the main body portion 32. As a result, when the positioning and fixing electric wire 22 is likely to be displaced with respect to the main body portion 32, the retaining portion 25 is caught by the peripheral edge of the through hole 38, and the displacement is hardly caused.

  In the example shown in FIG. 11, the retaining portion 25 is formed by brazing a part of the positioning and fixing wire 22 in a ring shape. The retaining portion 25 brazed in a ring shape is formed, for example, by heating the electric wire 20 together with the core member in a state where the electric wire 20 is wound around the core member. However, it is not essential that the clasp 25 is formed by being brazed. For example, the retaining portion 25 may be formed such that a part of the positioning and fixing electric wire 22 is tied or knitted.

  In addition, each structure demonstrated by the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  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.
