  Drawing 1 is a perspective view showing covering member 1 for wire harnesses concerning an embodiment. FIG. 2 is a side view showing the wire harness covering member 1 when the wire harness covering member 1 is viewed from the first direction DR1 shown in FIG. In FIG. 2, the thickness of the base material 2, the adhesive 4 and the separator 3 included in the wire harness covering member 1 is emphasized so that the structure of the wire harness covering member 1 can be easily understood. 1 is illustrated. Hereinafter, the wire harness covering member 1 is simply referred to as a “covering member 1”.

  As shown in FIGS. 1 and 2, the covering member 1 has a sheet-like shape as a whole, and a base material 2 having a pressure-sensitive adhesive 4 provided on the surface thereof, and is temporarily attached to the base material 2 by the pressure-sensitive adhesive 4. Separator 3 (release paper). When the covering member 1 is attached to the wire harness, the base material 2 is attached to the wire harness with the adhesive 4 and wound after the separator 3 is peeled off from the base material 2.

  FIG. 3 is a perspective view showing a wire harness 100 (hereinafter referred to as “wire harness 100 with a covering member”) around which the base material 2 of the covering member 1 is wound. FIG. 2 is a side view showing the wire harness 100 with a covering member when the wire harness 100 with a covering member is viewed from the extending direction. The wire harness 100 with a covering member according to the present embodiment is arranged in a vehicle such as an automobile, for example.

  The wire harness 100 includes an electric wire bundle 101 composed of a plurality of electric wires. A connector (not shown) is attached to each of both ends of the wire bundle 101. A base material 2 of the covering member 1 is attached to and wrapped around a part of the wire bundle 101 in the longitudinal direction by an adhesive 4. Thereby, the part outer peripheral surface of the wire bundle 101 is covered with the covering member 1, specifically, the base material 2 of the covering member 1.

  The base material 2 is a rectangular sheet-like member, and is formed of, for example, urethane foam. The wire bundle 101 can be protected by winding the base material 2 made of urethane foam around the wire bundle 101, and abnormal noise is generated when a surrounding interference object hits the wire harness 100 with the covering member. Can be suppressed. In addition, you may form the base material 2 with an EPDM foam.

  The substrate 2 includes a first main surface 21 and a second main surface 22 that faces the first main surface 21. The pressure-sensitive adhesive 4 is formed in layers on the entire first main surface 21. Thereby, the 1st main surface 21 of the base material 2 is an adhesion surface. The base material 2 includes a first end 23a and a second end 23b extending along a first direction DR1 perpendicular to the thickness direction, and a second perpendicular to the thickness direction and the first direction DR1. A third end 23c and a fourth end 23d extending along the direction DR2 are provided.

  As shown in FIGS. 3 and 4, the base material 2 is such that the first main surface 21 (adhesive surface) provided with the adhesive 4 is on the inside, and the third end portion 23 c and the fourth end portion 23 d. Is wound around the wire bundle 101 so that the first end portion 23a and the second end portion 23b overlap each other so that the first end portion 23a and the second end portion 23b overlap each other. Thereby, the base material 2 is wound around the wire harness 100 as if it were the rolled sushi where seaweed was wound around vinegared rice. Hereinafter, such a winding method of the base material 2 is referred to as “sushi winding”.

  The separator 3 is a rectangular fill member that is thinner than the substrate 2. The outer dimensions of the separator 3 are the same as the outer dimensions of the substrate 2 except for the thickness dimension. The separator 3 and the base material 2 are laminated | stacked through the adhesive 4 so that the vertical direction and a horizontal direction may respectively correspond. The separator 3 is temporarily attached to the base material 2 with the adhesive 4 and can be peeled off from the base material 2.

  The separator 3 is provided with a notch 30 that extends from one end to the other end in the first direction DR1. The notch 30 is provided along the first direction DR1 at the center of the separator 3 in the second direction DR2, for example. The separator 3 includes a first portion 31 and a second portion 32 that are aligned with the notch 30 in the second direction DR2. The cut 30 may be provided in the separator 3 other than the center in the second direction DR2.

  In the present embodiment, in the base material 2, the adhesive force of the adhesive 4 is stronger at the both ends in the second direction DR <b> 2, that is, at the first end 23 a and the second end 23 b than at other portions. Yes. That is, in the adhesive 4, the adhesive force is stronger in the portions on the first end portion 23a and the second end portion 23b of the base material 2 than in the other portions.

  Hereinafter, the portion of the adhesive 4 on the first end 23a of the base 2 is referred to as “first strong adhesive region 41”, and the portion of the adhesive 4 on the second end 23b of the base 2 is “ This is referred to as “second strong adhesion region 42”. The first strong adhesion region 41 exists from one end to the other end in the first direction DR1 in the first end portion 23a of the base material 2, and the second strong adhesion region 42 is in the second end portion 23b of the base material 2. The first direction DR1 exists from one end to the other end. Further, the first end portion 23a of the base material 2 may be referred to as a “first strong adhesive end portion 23a”, and the second end portion 23b of the base material 2 may be referred to as a “second strong adhesive end portion 23b”.

  Thus, in the base material 2, since the adhesive force of the adhesive 4 is strong at the first end portion 23a and the second end portion 23b, the separator 3 is bonded to the first end portion 23a. It is difficult to peel off from the base material 2 at the part which is adhered to the second end 23b.

  In addition, in the adhesive 4, the 1st strong adhesion area | region 41 and the 2nd strong adhesion area | region are changed by changing the component mixing | blending in the 1st strong adhesion area | region 41 and the 2nd strong adhesion area | region 42 with the component mixing | blending in another part. The adhesive force of 42 can be strengthened. Alternatively, in the adhesive 4, the first strong adhesive region 41 and the second strong adhesive region 42 are made thicker than the thicknesses of the other portions by making the thickness of the first strong adhesive region 41 and the second strong adhesive region 42 larger. Adhesive strength can be increased.

  Moreover, in this Embodiment, when the base material 2 is bent so that it may become convex on the separator 3 side, the separator 3 will partly peel from the notch 30. In other words, when the base material 2 is bent so that the first main surface 21 and the second main surface 22 thereof are on the outer side and the inner side, respectively, the separator 3 is partially peeled from the cut 30. Furthermore, in other words, the adhesive force in the portion other than the first strong adhesive region 41 and the second strong adhesive region 42 in the adhesive 4 is such that the separator 3 is bent when the base material 2 is bent so as to protrude toward the separator 3 side. It is a grade which peels from the notch 30. FIG. Thereby, when peeling the separator 3 from the base material 2, it can suppress that an operator's hand etc. touch the adhesive 4. FIG. Further, unlike the case where an operator pinches the end portion of the base material 2 and peels the separator 3, the end portion of the base material 2 is prevented from being rounded when the separator 3 is peeled from the base material 2. be able to. Therefore, the base material 2 can be appropriately attached and wound around the wire harness 100.

  Next, a method for attaching the covering member 1 to the wire harness 100 will be described. 5-11 is a figure which shows an example of the attachment method of the coating | coated member 1 with respect to the wire harness 100. FIG. Hereinafter, an example in which the worker manually attaches the covering member 1 to the wire harness 100 will be described. However, the machine may automatically attach the covering member 1 to the wire harness 100.

  First, as shown in FIG. 5, an operator holding the covering member 1 in the direction in which the wire bundle 101 of the wire harness 100 extends and the direction in which the notch 30 provided in the separator 3 of the covering member 1 extends. The covering member 1 is disposed above the wire bundle 101 so that the two are parallel to each other. At this time, the covering member 1 is disposed above the wire bundle 101 so that the separator 3 is positioned on the wire bundle 101 side. Further, the position of the wire bundle 101 is fixed by being supported by a support jig (not shown).

  Next, as shown in FIG. 6, the operator holds both ends of the covering member 1 in the second direction DR2, and both ends of the base member 2 in the second direction DR2, that is, the first strong adhesive end portions. 23a and the second strong adhesion end portion 23b are brought close to each other, and the base material 2 is bent into a U shape so as to protrude toward the separator 3 side. In other words, the operator holds the both end portions in the second direction DR2 of the covering member 1 along the first direction DR1 so that the adhesive surface (first main surface 21) of the base member 2 faces outward. The substrate 2 is bent in a U shape around the axis. As a result, the separator 3 is partially peeled from the cut 30. Specifically, in the separator 3, the first portion 31 on the first strong adhesion end portion 23 a side of the base material 2 with respect to the notch 30 is partially peeled from one end on the notch 30 side, and is more basic than the notch 30. The second portion 32 on the second strong adhesion end portion 23b side of the material 2 is partially peeled from one end on the cut 30 side. At this time, in the separator 3, at least a portion held by the operator, that is, a portion bonded to the first strong adhesive end portion 23a and a portion bonded to the second strong adhesive end portion 23b, Does not peel from material 2.

  Next, as shown in FIG. 7, the worker holds the both ends of the covering member 1 in the second direction DR2 and bends the base material 2 into a U-shape. The part exposed by partially peeling from the notch 30 is attached to the wire bundle 101 of the wire harness 100 by the adhesive 4 on the first main surface 21.

  Next, as shown in FIG. 8, the operator holds the first end 31 and the second end 32 of the separator 3 while holding one end of both ends of the covering member 1 in the second direction DR2. Among these, the base material 2 is affixed on the wire bundle 101 while pulling down the other end of the two ends. Here, for example, the operator attaches the base material 2 to the wire bundle 101 while pulling down the first portion 31. At this time, the first portion 31 is pulled to attach the base material 2 to the wire bundle 101 as much as possible. In the base material 2, since the adhesive force of the adhesive 4 at the first strong adhesive end portion 23 a is strong, when pulling the first portion 31 and attaching the base material 2 to the wire bundle 101, As shown in FIG. 8, the first portion 31 is in a state of being bonded to the first strong adhesive end portion 23a. That is, the adhesive force of the adhesive 4 at the first strong adhesive end portion 23a (adhesive force of the first strong adhesive region 41 of the adhesive 4) is applied to the wire bundle 101 by pulling the first portion 31. At the time of attachment, the first portion 31 has an adhesive force that does not peel from the first strong adhesive end portion 23a. Therefore, in the process of FIG. 8, the operator attaches the base material 2 to the wire bundle 101 in a state where the first portion 31 is adhered to the first strong adhesion end portion 23 a while pulling the first portion 31. Become.

  In addition, in the state of FIG. 7, when there exists a part adhering to the base material 2 other than the part adhering to the 1st strong adhesion edge part 23a among the 1st parts 31, the said part is When the first portion 31 is pulled down, the first portion 31 is peeled off from the substrate 2.

  Next, the operator pulls the first portion 31 of the separator 3 while holding the end portion on the second strong adhesion end portion 23b side of the both end portions in the second direction DR2 of the covering member 1, The first portion 31 is peeled from the first strong adhesive end portion 23a. Then, as shown in FIG. 9, the worker attaches the first strong adhesion end portion 23 a to the wire bundle 101 of the wire harness 100. Thereby, the half by the side of the 1st strong adhesion edge part 23a in the base material 2 is affixed on the wire bundle 101. FIG.

  Next, as shown in FIG. 10, the operator pulls the base member 2 to the wire bundle 101 while pulling down one of the first portion 31 and the second portion 32 of the separator 3 that has not been pulled down in the step of FIG. 8. Paste to. Here, the operator attaches the base material 2 to the wire bundle 101 while pulling down the second portion 32. At this time, the second portion 32 is pulled so that the substrate 2 is attached to the wire bundle 101 as much as possible. In the base material 2, since the adhesive force of the adhesive 4 at the second strong adhesive end portion 23b is strong, when pulling the second portion 32 and sticking the base material 2 to the wire bundle 101, As shown in FIG. 10, the second portion 32 is in a state of being bonded to the second strong adhesion end portion 23b. That is, the adhesive force of the adhesive 4 at the second strong adhesive end portion 23b (the adhesive force of the second strong adhesive region 42 of the adhesive 4) is applied to the wire bundle 101 by pulling the second portion 32. At the time of attachment, the second portion 32 has an adhesive force that does not peel from the second strong adhesive end portion 23b. Therefore, in the process of FIG. 10, the operator attaches the base material 2 to the wire bundle 101 in a state where the second portion 32 is adhered to the second strong adhesion end portion 23 b while pulling the second portion 32. become.

  In addition, in the state of FIG. 9, when there exists a part adhering to the base material 2 other than the part adhering to the 2nd strong adhesion edge part 23b among the 2nd parts 32, the said part is When the second portion 32 is pulled down, it peels off from the base material 2.

  Next, the operator pulls the second portion 32 of the separator 3 to separate the second portion 32 from the second strong adhesion end portion 23b. Then, as shown in FIG. 11, the operator attaches the second strong adhesion end portion 23 b so as to overlap the portion of the base material 2 that is attached to the wire bundle 101. In this example, the second strong adhesion end portion 23b is attached so as to be overlapped with the first strong adhesion end portion 23a attached to the wire bundle 101. Thereby, the half by the side of the 2nd strong adhesion edge part 23b in the base material 2 is affixed on the wire bundle 101, the attachment of the coating | coated member 1 with respect to the wire harness 100 is completed, and the base material 2 is wound by a stake roll. A wire harness 100 with a covering member is obtained.

  In the above example, when the separator 3 is peeled from the base material 2, the second portion 32 is peeled after the first portion 31 is peeled, but the first portion 31 is peeled after the second portion 32 is peeled off. It may be peeled off.

  In the above example, the covering member 1 is arranged above the wire bundle 101 and the base material 2 is wound around the wire bundle 101. However, the covering member 1 and the wire when the base material 2 is wound around the wire bundle 101 are used. The positional relationship with the bundle 101 is not limited to this. For example, the covering member 1 may be disposed below the wire bundle 101 and the base material 2 may be wound around the wire bundle 101. In this case, the base material 2 is wound around the wire bundle 101 while pulling up the first portion 31 and the second portion 32 of the separator 3.

  In the above example, the base material 2 is wound around the wire bundle 101 by squeezing. However, the adhesive 4 side surface of the first strong adhesive end portion 23a and the adhesive 4 of the second strong adhesive end portion 23b are used. The base material 2 may be wound around the wire bundle 101 so that the side surface is bonded. Thereby, the base material 2 is wound around the wire harness 100 as if both arms at the time of a palm. Hereinafter, such a method of winding the base material 2 is referred to as “pasting”.

  When winding the base material 2 around the wire bundle 101 by worshiping, the operator simultaneously removes the first portion 31 and the second portion 32 of the separator 3 from the state shown in FIG. 7 as shown in FIG. The substrate 2 is attached to the wire bundle 101 as much as possible while pulling down. At this time, in the state of FIG. 7, if there is a portion bonded to the base material 2 other than the portion bonded to the first strong adhesion end portion 23 a in the first portion 31, the portion Is peeled off from the base material 2 when the first portion 31 is pulled down, and is bonded to the base material 2 except for the portion of the second portion 32 that is bonded to the second strong adhesion end portion 23b. If there is a portion, the portion will peel from the substrate 2 when the second portion 32 is pulled down.

  Next, the operator pulls the first portion 31 to separate the first portion 32 from the first strong adhesion end portion 23a, and pulls the second portion 32 to pull the second portion 32 to the second strong strength. Peel from the adhesive end 23b. And as FIG. 13 shows, an operator bonds the surface by the side of the adhesive 4 of the 1st strong adhesion edge part 23a, and the surface by the side of the adhesive 4 of the 2nd strong adhesion edge part 23b. And the base material 2 is affixed on the part in which the base material 2 is not yet affixed among the parts which should be covered with the base material 2 in the wire bundle 101. Thereby, the wire harness 100 with the coating | coated member by which the wire bundle 101 was covered with the base material 2 and the base material 2 was wound by adhering is obtained.

  As described above, in the present embodiment, when the base material 2 is bent so as to be convex toward the separator 3, the separator 3 is partially peeled off from the cut 30. It can suppress that an operator's hand etc. touch the adhesive 4 at the time of peeling. Moreover, since it is not necessary to pinch the edge part of the base material 2 and peel off the separator 3, it can suppress that the adhesive surfaces adhere | attach at the said edge part, and the said edge part bends and becomes round. Therefore, the base material 2 can be appropriately attached and wound around the wire harness 100.

  Further, when the separator 3 does not have the notch 30 and the thickness of the base material 2 is very thin, it is difficult to peel the separator 3 from the end. However, in the present embodiment, the thickness of the base material 2 is extremely high. The separator 3 can be easily peeled off.

  Moreover, in this Embodiment, since the adhesive force of the adhesive 4 in the 1st edge part 23a of the base material 2 has become strong, the 1st part 31 of the separator 3 is pulled as mentioned above, and the base material 2 Can be attached to the wire harness 100. Therefore, when the base material 2 is affixed to the wire harness 100, it is possible to prevent the operator's hand from touching the adhesive 4. As a result, the base material 2 can be more appropriately attached and wound around the wire harness 100.

  Similarly, in the present embodiment, since the adhesive force of the adhesive 4 at the second end portion 23b of the substrate 2 is strong, the substrate 3 is pulled by pulling the second portion 32 of the separator 3 as described above. 2 can be attached to the wire harness 100. Therefore, when the base material 2 is affixed to the wire harness 100, it is possible to prevent the operator's hand from touching the adhesive 4. As a result, the base material 2 can be more appropriately attached and wound around the wire harness 100.

  Note that the adhesive force of the adhesive 4 does not have to be increased at the first end portion 23 a of the substrate 2. In this case, it becomes difficult to stick the substrate 2 to the wire harness 100 by pulling the first portion 31 of the separator 3. Therefore, in this case, the first portion 31 is entirely peeled off before the half on the first end portion 23a side of the base material 2 is attached to the wire harness 100, and then the first end portion 23a side of the base material 2 is provided. The half is affixed to the wire harness 100 so as to be pressed against the wire harness 100 from the second main surface 22 side of the substrate 2 by hand.

  Further, the adhesive force of the adhesive 4 may not be increased at the second end portion 23b of the substrate 2. In this case, it becomes difficult to stick the substrate 2 to the wire harness 100 by pulling the second portion 32 of the separator 3. Therefore, in this case, the second portion 32 is entirely peeled off before the half of the base 2 on the second end 23b side is attached to the wire harness 100, and then the second end 23b side of the base 2 is removed. The half is affixed to the wire harness 100 so as to be pressed against the wire harness 100 by hand from the second main surface 22 side.
