It is a perspective view which shows the modification of the coating | coated member for wire harnesses. It is a figure which shows a mode that a wire harness is put into the elongate curved space of a vehicle.

  FIG. 1 is a perspective view showing a wire harness 100 (hereinafter referred to as “wire harness 100 with a covering member”) around which a covering member 1 for wire harness 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. The wire harness covering member 1 is wound around a part of the electric wire bundle 101 in the longitudinal direction, whereby the part of the outer peripheral surface is covered with the wire harness covering member 1. Hereinafter, the wire harness covering member 1 is simply referred to as a “covering member 1”.

  The covering member 1 has a function of protecting the wire bundle 101 of the wire harness 100 and a function of regulating the path of the wire harness 100. The covering member 1 is composed of a sheet-like resin member 2. The sheet-like resin member 2 is wound around the wire harness 100. Specifically, it is wound around a part of the wire bundle 101 of the wire harness 100 in the longitudinal direction. The sheet-like resin member 2 can be repeatedly bent and plastically deformed. That is, the sheet-like resin member 2 can be repeatedly bent and deformed, and can maintain the deformed shape.

  FIG. 3 is a perspective view showing the covering member 1 before being wound around the wire harness 100. As shown in FIG. 3, the sheet-like resin member 2 constituting the covering member 1 is, for example, a rectangular sheet-like member. The sheet-like resin member 2 includes a first end 20a and a second end 20b 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 20c and a fourth end 20d extending along the direction DR2 are provided. That is, the sheet-like covering member 1 includes a first end portion 10a and a second end portion 10b extending along the first direction DR1 perpendicular to the thickness direction, and the thickness direction and the first direction DR1 perpendicular to the first direction DR1. And a third end portion 10c and a fourth end portion 10d extending along the second direction DR2.

  As shown in FIGS. 1 and 2, the sheet-like resin member 2 includes a first end 20 a and a second end so that the third end 20 c and the fourth end 20 d are along the circumferential direction of the wire bundle 101. It is wound around the wire bundle 101 so as to overlap the portion 20b. In other words, the covering member 1 is configured so that the third end portion 10c and the fourth end portion 10d are along the circumferential direction of the wire bundle 101, and the first end portion 10a and the second end portion 10b overlap each other. It is wound around the bundle 101. Since the sheet-like resin member 2 can be repeatedly bent and plastically deformed, the shape of the sheet-like resin member 2 is maintained when the sheet-like resin member 2 is wound around the wire bundle 101 and bent into a tubular shape. Therefore, it is not necessary to bond the overlapped first end 20a (first end 10a) and second end 20b (second end 10b) with an adhesive tape or the like.

  The sheet-like resin member 2 is formed, for example, by uniaxially stretching a polyolefin resin, specifically, a polyethylene resin 5 to 40 times, and has a thickness of, for example, 0.3 mm. The first direction DR1 described above is the extending direction of the sheet-like resin member 2. The sheet-like resin member 2 has a uniaxial molecular orientation in which molecules are oriented along the first direction DR1 (stretching direction). The sheet-like resin member 2 is easy to bend in the second direction DR2, and is difficult to bend in the first direction DR1. The sheet-like resin member 2 is wound around the wire bundle 101 so as to be bent in the second direction DR2 that is easily bent. In other words, the sheet-like resin member 2 is wound around the wire bundle 101 so as to bend around an axis along the first direction DR1. In other words, the sheet-like resin member 2 is wound around the electric wire bundle 101 so that the extending direction thereof is along the extending direction of the electric wire bundle 101.

  In the sheet-like resin member 2, the tensile elastic modulus in the second direction DR2 is 10 GPa or more (for example, 15.4 GPa). In the sheet-like resin member 2, the tensile strength in the second direction DR2 is 15 MPa or more (for example, 20 MPa). And in the sheet-like resin member 2, the tensile elongation in 2nd direction DR2 is 0.7% or more (for example, 1%).

  In the sheet-like resin member 2, the tensile elastic modulus in the first direction DR1 (stretching direction) is 10 GPa or more (for example, 15.4 GPa). In the sheet-like resin member 2, the tensile strength in the first direction DR1 is 300 MPa or more (for example, 440 MPa). And in the sheet-like resin member 2, the tensile elongation in 1st direction DR1 is 5% or more (for example, 7%).

  Thus, in the sheet-like resin member 2, it is comparatively strong with respect to the tensile force in the first direction DR1, and is comparatively weak with respect to the tensile force in the second direction DR2.

  The sheet-like resin member 2 having the above characteristics can be formed by, for example, “Forte (registered trademark)” which is a product of Sekisui Molding Co., Ltd. Specifically, the sheet-like resin member 2 can be formed of a forte single-layer sheet.

  The sheet-like resin member 2 can be bent into a cylindrical shape by repeating it several tens of times or more around an axis along the first direction DR1 (stretching direction, molecular orientation direction). That is, the sheet-like resin member 2 is bent around the axis along the first direction DR1 and then returned to a flat shape, and then again around the axis along the first direction DR1. It is possible to repeatedly perform the bending process. Therefore, the sheet-like resin member 2 can be repeatedly wound around the wire bundle 101 several tens of times. In other words, the covering member 1 can be repeatedly wound around the wire bundle 101 several tens of times. For example, the covering member 1 can be wound around the wire bundle 101 repeatedly 30 times or more.

  Next, a method for attaching the covering member 1 to the wire harness 100 will be described. First, as shown in FIG. 4, according to the diameter of the wire bundle 101 of the wire harness 100 around which the sheet-like resin member 2 is wound, the first end portion 20a and the second end portion 20b are preliminarily cylindrical. A closed sheet-shaped resin member 2 is prepared. In other words, the sheet-shaped resin member 2 that is bent and deformed in advance into the same shape as that wound around the wire harness 100 is prepared. The sheet-like resin member 2 is bent into a cylindrical shape according to the diameter of the wire bundle 101 by, for example, being wound around a rod-like member having the same diameter as the wire bundle 101. In a manufacturing factory where the covering member 1 is attached to the wire harness 100 (manufacturing factory of the wire harness 100 with a covering member), the covering member 1 is closed in a cylindrical shape in advance as shown in FIG. Delivered).

  Next, as shown in FIG. 5, the operator opens the sheet-like resin member 2 closed in a cylindrical shape with his / her hand or jig or the like in a curved state. That is, the operator opens and deforms the sheet-shaped resin member 2 as much as possible so that the wire harness 100 can be put inside the sheet-shaped resin member 2 so that the cylindrical shape of the sheet-shaped resin member 2 is maintained as much as possible. And as FIG. 6 shows, the electric wire bundle 101 of the wire harness 100 is arrange | positioned inside the sheet-like resin member 2 opened in the curved state. Thereafter, the sheet-like resin member 2 is closed in a cylindrical shape so that the first end portion 20 a and the second end portion 10 b overlap, and the sheet-like resin member 2 is wound around the wire bundle 101. Thereby, the wire harness 100 with a covering member as shown in FIGS.

  In addition, the covering member 1 and the wire harness at the boundary portion between the one end of the covering member 1 and the wire harness 100 in the extending direction of the wire harness 100 so that the attachment position of the covering member 1 with respect to the wire harness 100 is not shifted. You may wind an adhesive tape over 100. At this time, an adhesive tape may be wound over both the covering member 1 and the wire harness 100 also at the boundary portion between the other end of the covering member 1 and the wire harness 100 in the extending direction of the wire harness 100.

  As described above, the covering member 1 according to the present embodiment is provided with the sheet-like resin member 2 that can be repeatedly bent and plastically deformed. Therefore, as shown in FIG. By preparing the sheet-like resin member 2, in other words, by preparing the sheet-like resin member 2 that has been bent and deformed in advance to the same shape as that wound around the wire harness 100, the sheet as described above The sheet-like resin member 2 can be wound around the wire harness 100 simply by opening and closing the resin-like resin member 2. Therefore, the covering member 1 can be easily attached to the wire harness 100.

  On the other hand, a covering member made of a soft sheet-like member that cannot be repeatedly bent plastically deformed (hereinafter referred to as a “soft sheet-like covering member”) or a covering made of a soft tubular member When the wire harness 100 is covered with a member (hereinafter referred to as a “tubular covering member”), it is difficult to easily attach the covering member to the wire harness 100.

  When covering the wire harness 100 with the soft sheet-like covering member, for example, the soft sheet-like covering member is folded in half with the wire harness 100 interposed therebetween so that the both end portions thereof are aligned, The parts are bonded with a double-sided adhesive tape. At this time, it is necessary to attach both ends carefully so as not to shift. And after the edge part of the soft sheet-like coating member bonded together is bent, an adhesive tape is wound around the boundary part of a soft sheet-like coating member and the wire harness 100.

  Moreover, when using a tubular covering member, it is necessary to pass each of the some electric wire which comprises the electric wire bundle 101 of the wire harness 100 through a tubular covering member. At this time, when passing each electric wire through the tubular covering member with the terminal inserted into the connector attached to the end of each electric wire, carefully connect each electric wire so that the tubular covering member is not damaged by the terminal. Needs to pass through the tubular covering member.

  Thus, when using a covering member such as a soft sheet-like covering member or a tube-like covering member, it is difficult to easily attach the covering member to the wire harness 100. In this Embodiment, since the coating | coated member 1 provided with the sheet-like resin member 2 which can be repeatedly bent plastically deformed is used, the coating | coated member 1 can be easily attached to the wire harness 100 as mentioned above.

  Moreover, since the sheet-like resin member 2 can maintain the cylindrical closed state, the sheet-like resin member 2 is placed in the predetermined direction with respect to the wire harness 100 as in the present embodiment. By winding so that both ends overlap, it is possible to eliminate the need for a process of winding an adhesive tape around the sheet-shaped resin member 2 in order to prevent the sheet-shaped resin member 2 from opening and the wire harness 100 from being exposed. It becomes. Therefore, in this case, workability when attaching the covering member 1 to the wire harness 100 is improved.

  In addition, in order to suppress that, when the sheet-like resin member 2 wound around the wire harness 100 becomes easy to open by arranging the wire harness 100 with the covering member in a place where vibration in the vehicle is large, etc. An adhesive tape may be wound around the sheet-like resin member 2.

  Moreover, when using the above-mentioned tubular covering member, a connector is attached to the end of the electric wire bundle after passing each electric wire of the electric wire bundle through the tubular covering member. The wire bundle 101 can be covered with the covering member 1 with the connector attached to the end.

  Moreover, when making the attachment position of the covering member 1 with respect to the wire harness 100 not shift | deviate, it adheres to the boundary part of the wire harness 100 and the covering member 1 in the state in which the covering member 1 is wound with respect to the wire harness 100. Since the tape can be wound, the operation is easy.

  In the above example, the covering member 1 is composed of one sheet-like resin member 2, but a sheet-like resin member obtained by laminating a plurality of sheet-like resin members 2 having the above-described characteristics is a wire. It may be wound around the harness 100. In this case, it is desirable to laminate a plurality of sheet-like resin members 2 so that the extending directions (molecular orientation directions) of the two lower-layer and upper-layer sheet-like resin members 2 laminated with each other are orthogonal to each other. For example, when three sheet-like resin members 2 are laminated, the extending directions of the first and second sheet-like resin members 2 are orthogonal to each other, and the second and third sheet-like resin members 2 Stretch directions are orthogonal. When the four sheet-like resin members 2 are laminated, the extending directions of the first and second sheet-like resin members 2 are orthogonal to each other, and the second and third-layer sheet-like resin members 2 The stretching directions are orthogonal, and the stretching directions of the third-layer and fourth-layer sheet-like resin members 2 are orthogonal. As a result, it is possible to obtain a sheet-like resin member that is strong against pulling in both the first direction DR1 and the second direction DR2 and is easily bent in both the first direction DR1 and the second direction DR2.

  In the covering member 1, a sheet-like abnormal noise suppressing member may be laminated and attached to the sheet-like resin member 2. FIG. 7 is a perspective view showing the wire harness 100 with a covering member around which the covering member 1 including the sheet-like resin member 2 and the sheet-like abnormal noise suppressing member 3 stacked on each other is wound. FIG. 8 is a side view showing the wire harness 100 with a covering member when the wire harness 100 with a covering member shown in FIG. 7 is viewed from its extending direction. Hereinafter, the covering member 1 shown in FIGS. 7 and 8 is referred to as a “covering member 1A”. The wire harness 100 around which the covering member 1A is wound is referred to as “wire harness 100A”, and the wire harness 100 with the covering member around which the covering member 1A is wound is referred to as “wire harness 100A with covering member”. FIG. 9 is a perspective view showing the covering member 1A before being wound around the wire harness 100A.

  As shown in FIG. 9, the covering member 1 </ b> A has a sheet shape as a whole. In the covering member 1 </ b> A, the sheet-like abnormal noise suppressing member 3 is laminated and attached to the sheet-like resin member 2. The sheet-like abnormal noise suppressing member 3 is a member for suppressing the generation of abnormal noise when the wire harness with covering member 100A hits a surrounding interference object. The sheet-like abnormal noise suppressing member 3 is softer than the sheet-like resin member 2 and has elasticity. The sheet-like resin member 2 is formed of, for example, a crosslinked foamed resin. As this crosslinked foamed resin, for example, crosslinked foamed polyethylene can be employed. Such a sheet-like abnormal noise suppressing member 3 can be formed of, for example, “Softlon (registered trademark) S” which is a product of Sekisui Chemical Co., Ltd.

  Similarly to the sheet-like resin member 2, the sheet-like abnormal noise suppressing member 3 is a rectangular sheet-like member. The outer dimensions of the sheet-like abnormal noise suppressing member 3 are the same as the outer dimensions of the sheet-like resin member 2 except for the thickness dimension. The thickness of the sheet-like abnormal noise suppressing member 3 is larger than the thickness of the sheet-like resin member 2.

  The sheet-like abnormal noise suppressing member 3 and the sheet-like resin member 2 are laminated with each other so that the vertical direction and the horizontal direction coincide with each other. The sheet-like abnormal sound suppressing member 3 and the sheet-like resin member 2 are bonded to each other by welding, for example. In this example, since each of the sheet-like abnormal sound suppressing member 3 and the sheet-like resin member 2 is made of polyethylene, it is possible to easily weld them. As welding at the time of bonding the sheet-like abnormal sound suppressing member 3 and the sheet-like resin member 2, thermal welding or ultrasonic welding can be employed. The sheet-like abnormal noise suppressing member 3 and the sheet-like resin member 2 may be bonded to each other by an adhesive instead of welding.

  The covering member 1A having such a structure can be repeatedly wound around the wire bundle 101 several tens of times. The covering member 1A can be repeatedly wound around the wire bundle 101, for example, 30 times or more. As shown in FIGS. 7 and 8, the covering member 1 </ b> A has the third end portion 10 c and the fourth end portion 10 d along the circumferential direction of the wire bundle 101, and the first end portion 10 a and the second end portion 10 b. Are wound around the wire bundle 101 with the sheet-like noise suppressing member 3 facing outward. Thereby, the electric wire bundle 101 can be protected by the hard sheet-like resin member 2 on the inner side, and the generation of abnormal noise can be suppressed by the outer soft sheet-like noise suppressing member 3. In addition, unlike the sheet-like resin member 2, the sheet-like abnormal noise suppressing member 3 cannot be repeatedly bent and plastically deformed alone.

  The covering member 1A can be wound around the wire harness 100A in the same manner as the covering member 1 shown in FIG. First, according to the diameter of the wire bundle 101 of the wire harness 100A around which the covering member 1A is wound, the covering member 1A in a state of being closed in a cylindrical shape in advance so as to overlap the first end portion 10a and the second end portion 10b is prepared. (See FIG. 4). In other words, the covering member 1A that is bent and deformed in advance into the same shape as that wound around the wire harness 100A is prepared. The covering member 1A is delivered to the manufacturing plant where the covering member 1A is attached to the wire harness 100A in a state in which the covering member 1A is closed in a cylindrical shape (a state in which the covering member 1A is brazed).

  Next, the operator opens the covering member 1 </ b> A, which is closed in a cylindrical shape, with his / her hand or jig (see FIG. 5). And the electric wire bundle 101 is arrange | positioned inside the coating | coated member 1A opened in the curved state (refer FIG. 6). Thereafter, the covering member 1A is closed in a cylindrical shape so that the first end 10a and the second end 10b overlap, and the covering member 1A is wound around the wire bundle 101. Thereby, the wire harness 100A with a covering member as shown in FIGS. 7 and 8 is completed.

  Thus, since the covering member 1A is provided with the sheet-like resin member 2 that can be repeatedly bent and plastically deformed, the covering member 1A is opened by preparing the covering member 1A that is closed in a cylindrical shape in advance. The covering member 1A can be wound around the wire harness 100A simply by closing. Therefore, the covering member 1A can be easily attached to the wire harness 100A.

  In addition, since the covering member 1A can maintain a closed state in a cylindrical shape, the covering member 1A is wound around the wire harness 100A so that both end portions in a predetermined direction overlap each other. In order to prevent the wire harness 100 </ b> A from being exposed due to the opening of 1 </ b> A, it is possible to eliminate the process of winding an adhesive tape around the covering member 1 </ b> A. Therefore, in this case, workability when attaching the covering member 1A to the wire harness 100A is improved.

  In addition, as in this example, the sheet-like resin member 2 and the sheet-like noise suppressing member 3 are made by attaching the sheet-like noise suppressing member 3 in advance to the sheet-like resin member 2 as a single component. At the same time, it can be wound around the wire harness 100A. Therefore, workability is improved.

  Moreover, in the manufacturing factory which manufactures the wire harness 100A with a covering member, the sheet-like resin member 2 and the sheet-like abnormal noise suppression member 3 are attached to each other and delivered as one component. Makes parts management easier.

  In addition, as in this example, by welding the sheet-like abnormal noise suppressing member 3 to the sheet-like resin member 2, the sheet-like abnormal noise suppressing member 3 is hardly peeled off from the sheet-like resin member 2.

  The covering member 1A can be wound around the wire harness 100 regardless of where the wire harness 100 is routed. However, the wire harness is inserted from the end into an elongated bent space in the vehicle. It is particularly effective to wrap around 100.

  As shown in FIG. 10, when the wire harness 100 is routed by putting the wire harness 100 into an elongated curved space 500 in the vehicle from its end, if the wire harness 100 is soft, the wire harness 100 is placed in the back of the space 500. It becomes difficult to insert until. Since the relatively hard sheet-like resin member 2 that can be repeatedly bent and plastically deformed is provided on the covering member 1A, the wire harness 100 can be hardened by winding the covering member 1A around the wire harness 100. Therefore, it becomes easy to route the wire harness 100 in the space by using the covering member 1A so as to be wound around the wire harness 100 inserted from the end with respect to the long and narrow space in the vehicle. Further, since the sheet-like noise suppressing member 3 is laminated on the relatively hard sheet-like resin member 2, even if the wire harness 100 around which the covering member 1A is wound is arranged in a long and narrow space, the noise Can be prevented from occurring. In addition, as an elongate curved space in a vehicle, the space between an outer plate | board and an inner panel in a back door is mentioned, for example.
