OVERVIEW OF THE INVENTION TASKS TO BE SOLVED BY THE INVENTION

[0007] For this purpose, the applicant of the present application has proposed a method for directly attaching an insulating sheathing of the electrical conductor and a planar material by welding as a new method for attaching the electrical conductors and the planar outer element.

[0008] When an insulating sheath of an electrical conductor 91 and a planar material 92 are directly welded and attached to each other, as in the cable harness 90 which is in Fig. As shown in Figure 8, it is conceivable to provide a fastening element 93 for attaching the cable harness 90 to the vehicle at an end section of the flat material 92.

[0009] However, if in this case, in a state where the fastening element 93 is as described in Fig. As shown in Figure 9, where a connecting section 91a of an electrical conductor 91 is attached to a vehicle 94, is bent in a direction away from the flat material 92. Because the end section of the flat material 92 is fixed, the bending force tends to act as a force that detaches the electrical conductor 91 from the flat material 92. Furthermore, if the connecting section 91a is bent along its direction of extension (in the example shown in Figure 9), the bending force tends to act as a force that detaches the electrical conductor 91 from the flat material 92. Fig. 9 upwards) from the state of Fig. If the electrical conductor 91 is pulled, the pulling force tends to act as a force that detaches the electrical conductor 91 from the planar material 92. Accordingly, there is a risk that the electrical conductor 91 and the planar material 92 will be separated from each other.

[0010] Therefore, it is an object of the present invention to provide a technology that makes it possible to prevent a separation of electrical conductors and a flat material when a cable harness in which insulating sheaths of the electrical conductors and a flat material are directly welded and fastened is integrated into a vehicle. MEANS OF SOLVING THE TASK

[0011] To solve the above problems, a cable harness equipped with a fastening element, according to a first aspect, comprises a cable harness having an electrical conductor and a planar material with a conductor fastening section welded to an insulating sheath of the electrical conductor arranged on a principal surface of the planar material, wherein the cable harness has a weld area section in which the electrical conductors and the planar material are welded together and a terminal-side section located closer to a terminal section than to the weld area section;and a fastening element attached to the wiring harness and fastened to a vehicle, thereby fastening the wiring harness to the vehicle, wherein, in a state where the fastening element is attached to a fastening object, a bending force is exerted on the connection-side portion, the weld area section has a first portion that follows a bend of the connection-side portion and a second portion that is connected to a side of the first portion opposite the connection-side portion, and which is prevented by the holding force of the fastening element from following the bend of the connection-side portion.

[0012] A cable harness provided with a fastening element according to a second embodiment is the cable harness provided with a fastening element according to the first aspect, wherein, if the conductor fastening section in the first sub-area and in the second sub-area of ​​the planar material is defined as a first conductor fastening section and as a second conductor fastening section respectively, the fastening element is provided in the planar material on the second conductor fastening section or on a lateral extension section that extends laterally from the second conductor fastening section away from the electrical conductors.

[0013] A cable harness provided with a fastening element according to a third embodiment is the cable harness provided with a fastening element according to the first aspect, wherein if the conductor fastening section in the first sub-area and in the second sub-area of ​​the planar material is defined as a first conductor fastening section and as a second conductor fastening section respectively, the fastening element is provided on a front extension section that extends forward from the second conductor fastening section in the planar material.

[0014] A cable harness provided with a fastening element according to a fourth embodiment is the cable harness provided with a fastening element according to the third aspect, wherein the front extension section extends such that it is arranged in the planar material on a front side of a lateral extension section which extends to a lateral side of the second conductor fastening section and is connected to a lateral side of the first conductor fastening section, and a perforated line is formed at a boundary between the front extension section and the first conductor fastening section.

[0015] A cable harness provided with a fastening element according to a fifth embodiment is the cable harness provided with a fastening element according to one of the first to fourth aspects, wherein several spot-welded sections, in which the insulating sheathing and the flat material are partially welded, are formed in the welding area section at intervals along a direction of extension of the electrical conductor.

[0016] A cable harness provided with a fastening element according to a sixth embodiment is the cable harness provided with a fastening element according to one of the first to fourth aspects, wherein the insulating sheathing and the planar material are continuously welded along one extension direction of the electrical conductor in the welding area section. ADVANTAGEOUS EFFECTS OF THE INVENTION

[0017] According to each embodiment, when the wiring harness, in which the insulating sheaths of the electrical conductors and the flat material are directly welded and fastened, is integrated into the vehicle, the welded section of the flat material is designed such that, when a bending force is applied to the electrical conductors in a state where the fastening element is attached, the fastening element bends in such a way that it follows the bend. Thus, the bending force on the electrical conductors hardly acts as a force that separates the electrical conductors and the flat material. Furthermore, even if the electrical conductors are pulled in a state where the electrical conductors and the flat material are bent, a pulling force tends to act as a shear force between the electrical conductors and the flat material, and hardly acts as a force that separates the electrical conductors and the flat material.Accordingly, it can be prevented that the electrical conductors and the flat material separate from each other.

[0018] According to the second aspect, the electrical conductors can be bent at a position of the fastening element.

[0019] According to the third aspect, the fastening element can be located in a position that is offset from the bending position of the electrical conductors.

[0020] According to the fourth aspect, the perforated line is separated, and the front extension section is separated from the first conductor attachment section, allowing the first conductor attachment section to follow the bend of the electrical conductors of the first sub-area.

[0021] According to the fifth aspect, a qualitative evaluation of each spot weld section can easily be carried out.

[0022] According to the sixth aspect, the welding time can be reduced.

DESCRIPTION OF THE EXECUTION FORMS First embodiment

[0023] A cable harness equipped with a fastening element according to a first embodiment is described below. Fig. Figure 1 is a side view showing a cable harness 1 fitted with a fastening element according to the first embodiment. Fig. Figure 2 is a bottom view showing the cable harness 1 fitted with a fastening element according to the first embodiment.

[0024] The cable harness 1, equipped with a fastening element, has a cable harness 10 and a fastening element 40.

[0025] The wiring harness 10 is used as a cable element that is mounted on a vehicle and electrically connects devices. The wiring harness 10 comprises electrical conductors 20 and a planar (or track-shaped) material 30.

[0026] The electrical conductors 20 are insulated electrical conductors, comprising a core and an insulating sheath enclosing the core. The insulated electrical conductor can be a round conductor or a rectangular conductor.

[0027] The conductor core has one or more strands. Each strand is made of a conductive material, such as copper, a copper alloy, aluminum, or an aluminum alloy, and is arranged in a straight line. If the conductor core has multiple strands, the strands are preferably twisted.

[0028] The insulating sheathing is formed by extrusion molding of a synthetic plastic, such as polyvinyl chloride (PVC) or polyethylene (PE), around the core of the conductor, or by applying an insulating paint, such as enamel paint, around the core of the conductor.

[0029] In the Fig. In the example shown, a connector C is provided at a connection section of the electrical conductors 20. The electrical conductors 20 are connected, for example, via the connector C to a device mounted on a vehicle. The connector C has a connector housing, which is made, for example, of an insulating material, and a terminal that is connected to an end section of the electrical conductors 20 and is received in the connector housing.

[0030] The sheet material 30 is an element with a flexibility that allows bending deformation. The electrical conductors 20 are arranged on a main surface 31 of the sheet material 30. The sheet material 30 is welded to the insulating sheathing of the electrical conductors 20, which are arranged on the main surface 31. Welding positions W are shown by dot-dashed lines in the figures. In particular, there is no restriction regarding a welding method for welding the sheet material 30 and the insulating sheathing; for example, ultrasonic welding is conceivable. In particular, there is no restriction regarding the material that forms the sheet material 30, as long as it is possible to weld it to the insulating sheathing. A material is preferred that, in addition to the PVC and PE described above, contains a plastic, such as...comprising polypropylene (PP) and polyethylene terephthalate (PET), and even more preferably a material comprising the same plastic as that from which the insulating sheath is formed.

[0031] It is conceivable that the sheet material 30 is, for example, extruded and has a uniform cross-sectional shape. The sheet material 30 could also be, for example, a non-woven fabric or a foam board.

[0032] In the example that is in Fig. As shown in Figure 1, the planar material 30 is formed from a single layer. It is also conceivable, of course, that the planar material 30 is formed from two or more layers. If the planar material 30 is formed from two or more layers, a first layer, which has the main surface 31 described above, is a cable fastening layer to which the electrical conductors 20 are welded, and the other layer is selected appropriately in view of the function of the planar material 30.

[0033] The three electrical conductors 20 are arranged on the flat material 30, although the number of electrical conductors 20 can also be one, two, four, or more. There is no restriction regarding the path of the electrical conductors 20 arranged on the flat material 30. For example, the electrical conductors 20 can extend in a straight line on the flat material 30 or in a curve. If several electrical conductors 20 are arranged on the flat material 30, they can all extend in the same direction or they can partially extend in different directions. A bending section, at which the electrical conductors 20 branch, can also be formed on the flat material 30.

[0034] In this description, a section of the cable harness 10 where the electrical conductor 20 and the flat material 30 are welded together is referred to as the weld section 12. A section located closer to the connection section (here, the connector C) than weld section 12 is referred to as a connection-side section 16. Accordingly, a section of the electrical conductors 20 that is welded to the flat material 30 is referred to as the weld section 22, and a section located closer to the connection section (here, the connector C) than weld section 22 is referred to as a connection-side section 26. A section of the flat material 30 that is welded to the electrical conductor 20 is referred to as a conductor attachment section 32 ("attachment section 32, to which the electrical conductors are attached").

[0035] The welding area section 12 is a section comprising the welding section 22 of the electrical conductors 20 and the conductor fastening section 32 of the flat material 30. Within the welding area section 12, several spot weld sections W1, at which the insulating sheathing and the flat material 30 are welded section by section, are formed at intervals along one direction of extension of the electrical conductors 20. In the section 12, the welding area section 12 comprises the welding section 22 of the electrical conductors 20 and the conductor fastening section 32 of the flat material 30. Fig. In the example shown, the spot welding sections W1 are formed with a specific distance, although there can also be sections with different distances.

[0036] The connection-side section 16 is an area where the electrical conductors 20 and the flat material 30 are not welded together. Specifically, the connection-side section 16 is an area formed by the connection-side section 26, which extends from an end section of the flat material 30 to an outer surface and to the connector C, which is the connection section in the electrical conductor 20, and which does not include the flat material 30. For example, if the end section of the flat material 30 is not welded to the electrical conductor 20, the connection-side section 16 may also include the flat material 30. Furthermore, a base material of a flat material that is not connected to a base material of the flat material 30 forming the weld area section 12 may be welded to the connection-side section 26.Accordingly, the connection-side sub-area 16 is an area that does not have a planar material which is continuously connected to the planar material 30 which forms the welding area section 12, or an area which has a planar material which is connected to the planar material 30, but which is not welded to the electrical conductors 20.

[0037] The connection-side section 26 of the electrical conductors 20 is not welded to the flat material 30. Therefore, the connection-side sections 26 of the electrical conductors 20 do not interfere with each other before being connected to the connector C. The connection-side sections 26 are used, for example, to insert terminals provided at the end sections of the electrical conductors 20 into a cavity formed in the connector housing.

[0038] The fastening element 40 is used to attach the wiring harness 10 to the vehicle. The fastening element 40 is attached to the wiring harness 10. The wiring harness 10 is attached to the vehicle by attaching the fastening element 40 to the vehicle. The fastening element 40 is provided for the flat material 30. More precisely, the fastening element 40 is provided for a lateral extension section 35 of the flat material 30, which extends along a side of the electrical conductor 20. It is conceivable that the fastening element 40 could be a snap-in element 40, which can be inserted into a hole formed in a fastening object and snapped into place.

[0039] The locking element 40 has a locking piece 42 which can be inserted into and locked into a hole formed in a fastening object such as a vehicle body part, a column part 44 which extends from the locking piece 42, and a retaining part 46 which is provided at one end of the column part 44.

[0040] For example, a pair of locking pieces 42 is configured to extend from the end of the column part 44 to both sides and to be larger than a hole formed in the fastening object. When the pair of locking pieces 42 is inserted into the hole formed in the fastening object, it is elastically deformed so that it contracts, enabling it to pass through the hole, and after passing through the hole, it elastically expands again, thereby engaging a circumferential edge of the hole and snapping into place.

[0041] The column 44 is the part that connects the locking pieces 42 and the retaining part 46. The column part 44 passes through the flat material 30.

[0042] The retaining element 46 prevents the locking element 40 from coming out of the planar material 30. The retaining element 46 is, for example, designed in a plate-like form that is larger than the cross-sectional area of ​​the column part 44 and is located on the side of the planar material 30 that faces the locking elements 42.

[0043] It is not necessary to use the locking element 40 as the fastening element 40, and elements other than the locking element 40 can also be used. For example, it is conceivable to use a bolt or double-sided adhesive tape as the fastening element. Even if the locking element is used as the fastening element, there is no restriction regarding the shape described above and the method for attaching the fastening element to the flat material. For example, it is conceivable that the locking element is shaped like an umbrella. It is also conceivable, for example, that the column part does not penetrate the flat material 30, but rather that a base surface of the retaining part is connected to the flat material 30.

[0044] The cable harness 10 is fastened by the fastening element 40 in a state in which a main surface opposite the main surface 31, on which the electrical conductors 20 are arranged, faces the fastening object. Thus, the locking elements 42 of the locking element 40 are located on a side of the main surface opposite the main surface 31, on which the electrical conductors 20 are arranged.

[0045] If the cable harness 10 has the connection-side section 16 described above, and the fastening element 40 is provided near an end section of the weld positions W in the planar material 30 that is welded to the electrical conductors 20, as shown in Fig. In the example shown in Figure 8, when a bending force is applied to the connection-side part 16, it tends to act as a force that separates the electrical conductors 20 and the planar material 30.

[0046] Compared to the one in Fig. In contrast to the example shown in Figure 8, this description changes the position of the fastening element 40 with respect to the weld area section 12, so that when the bending force acts on the electrical conductors 20, the electrical conductors 20 and the planar material 30 are hardly separated from each other. This design is, in addition to the Fig. 1 and Fig. 2, with regard to Fig. 3 described in detail.

[0047] Fig. Figure 3 is a diagram showing a process during the bending of the cable harness 1 equipped with a fastening element according to the first embodiment.

[0048] This describes a process when the bending force is applied to the connection-side section 16 in a state in which the fastening element 40 is attached to a fastening object P (hereinafter referred to as a fastening state). As in Fig. As shown in Figure 3, the connector C is subsequently pulled so that it moves towards an upper side with respect to the fastening object P of the fastening element 40, thereby exerting the bending force on the connection-side section 16. Such a process can occur, for example, when integrating the wiring harness 10 into the vehicle, when the connector C is pulled while the fastening element 40 is being attached to secure the connector C.

[0049] If, as in Fig. As shown in Figure 3, when connector C is pulled and the connection-side section 16 is bent, a first section 13 of the welded area section 12 of the cable harness 10, which is connected to the connection-side section 16, is bent so that it follows the bend of the connection-side section 16. Meanwhile, a second section 14 of the welded area section 12 of the cable harness 10, which is connected on a side opposite the first section 13 (as viewed from the connection-side section 16), is prevented from following the bend of the connection-side section 16. This is achieved by the design in which the fastening element 40 is provided on the lateral extension section 35 of the flat material 30.

[0050] More precisely, a section of the welded section 22 of the electrical conductors 20, forming the first sub-area 13, is defined as a first section 23, and a section forming the second sub-area 14 is defined as a second section 24. Similarly, a section of the conductor fastening section 32 of the planar material 30, forming the first sub-area 13, is defined as a first conductor fastening section 33, and a section forming the second sub-area 14 is defined as a second conductor fastening section 34. The first conductor fastening section 33 is a section to which the first section 23 of the electrical conductors 20 is welded, and the second conductor fastening section 34 is a section to which the second section 24 of the electrical conductors 20 is welded.

[0051] The lateral extension section 35 of the planar material 30 described above, on which the fastening element 40 is provided, is a section that extends laterally from the second conductor fastening section 34 to the electrical conductors 20. In this case, lateral extension sections 35 are provided on both sides of the electrical conductors 20 from the second conductor fastening section 34. The fastening element 40 is provided on each lateral extension section 35.

[0052] In a state where the fasteners 40 are attached, the first conductor fastening section 33 of the planar material 30 has a free end. Thus, a section of the cable harness 10 located closer to connector C than to the first sub-area 13 has a free end. Accordingly, if connector C is, as in Fig. As shown in Figure 3, when the bending force is applied and the connection-side section 26 and the first section 23 of the electrical conductors 20 follow the bend. Subsequently, the first conductor fastening section 33 of the planar material 30 also follows the first section 23 of the electrical conductors 20. Accordingly, the first sub-section 13 follows the bend of the connection-side sub-section 16.

[0053] Due to the holding force of the fastening element 40, which is provided on the lateral extension section 35 extending laterally from the second conductor fastening sections 34, the second conductor fastening section 34 tends to remain in the same position. The planar material 30 is bent at a position between the first conductor fastening section 33 and the second conductor fastening section 34 such that the plane of the main surface 31 of the first conductor fastening section 33 intersects the plane of the main surface 31 of the second conductor fastening section 34. At this point, the second section 24 of the electrical conductor 20 is attached to the second conductor fastening section 34, causing the second section 24 of the electrical conductor 20 to also tend to remain in the same position.Accordingly, the holding force of the fastening element 40 prevents the second sub-area 14 from following the bend of the connection-side sub-area 16.

[0054] Accordingly, when the bending force is applied to the connection-side section 16, the first section 13 follows the bend of the connection-side section 16. In contrast, the holding force of the fastening element 40 prevents the second section 14 from following the bend of the connection-side section 16. In other words, the position of the fastening element 40 relative to the weld area section 12 is determined such that a section of the weld area section 12, where the electrical conductors 20 and the flat material 30 are welded, can follow the bend of the connection-side section 16. In this case, the first section 13 has three spot weld sections W1, but there is no restriction on the number of spot weld sections W1. The number of spot weld sections W1 can be one or two, or four or more.As the number of conductors increases, the electrical conductors 20 and the flat material 30 hardly separate from each other when the cable harness 10 is bent.

[0055] According to the wiring harness 1 with fastening element and the configuration described above, when the wiring harness 10, in which the insulating sheaths of the electrical conductors 20 and the flat material 30 are directly welded and fastened, is integrated into the vehicle, the welded section 12 is designed such that, when a bending force is applied to the connection-side section 16 in a state where the fastening element 40 is attached, it bends in such a way that it follows the bend. Thus, the bending force acts on the connection-side section 16 as a force that barely separates the electrical conductors 20 and the flat material 30.Furthermore, even if the connection-side section 16 is pulled in a state where the weld area section 12 is bent, the pulling force tends to act as a shear force on the electrical conductors 20 and the flat material 30, and acts as a force that hardly separates the electrical conductors 20 and the flat material 30. Accordingly, the separation of the electrical conductors 20 and the flat material 30 can be prevented.

[0056] The fastening element 40 is provided on the lateral extension section 35, which extends laterally from the second conductor fastening section 34 in the planar material 30 to the electrical conductors 20, allowing the electrical conductors 20 to be bent at the position of the fastening element 40.

[0057] The spot weld sections W1 are formed at intervals along the direction of extension of the electrical conductors 20, thus facilitating a qualitative evaluation of each spot weld section W1. More precisely, when a welding section is formed, welding conditions, such as the welding power of a welding machine and a welding time, are generally defined. By forming the spot weld sections W1 at this stage, it is easier to manage the welding conditions at each location, and errors can therefore be reduced, for example, compared to the case where the welding area section 12 is formed continuously. Thus, the qualitative evaluation of each spot weld section W1 can be easily performed.

[0058] It is of course also conceivable that the insulating sheathing and the flat material 30 are continuously welded along the direction of extension of the electrical conductors 20 without forming the spot weld sections W1. This means that it is also conceivable, as with a cable harness 1A equipped with a fastening element according to the in Fig. In the modification example shown in Figure 4, a continuous weld section W2 is formed, which is continuous within a welding area section 12A. Forming this weld section requires the process of inserting a part to be welded into the welding machine, welding it, and then releasing it. When forming the multiple spot weld sections W1, it is necessary to repeat the processes of inserting the parts to be welded into the welding machine and releasing them.In contrast, when forming the continuous weld section W2 in the welding area section 12A described above, the process of inserting the part to be welded into the welding machine and the process of releasing it from the machine is not repeated several times, compared to the case where several spot weld sections W1 are formed, thus reducing the welding time. Second embodiment

[0059] A cable harness equipped with a fastening element according to a second embodiment is described. Fig. Figure 5 is a bottom view showing a cable harness 101 fitted with a fastening element according to the second embodiment. In the description of the present embodiment, the same reference numerals are assigned to the same component elements described above, and a further description of these is omitted.

[0060] In the cable harness 101 provided with fastening element according to the second embodiment, the position of the fastening element 40 and the shape of the flat material 130 differ from the position of the fastening element 40 and the shape of the flat material 30 of the cable harness 1 provided with fastening element according to the first embodiment.

[0061] The fastening element 40 is provided on a front extension section 36 of the planar material 30, which extends from the second conductor fastening section 34 to a front side of the second section 24 of the electrical conductors 20. The front extension section 36 extends such that it connects to a front side of the lateral extension section 35, which extends laterally from the second conductor fastening sections 34. The front extension section 36 is located on a lateral side of the first conductor fastening section 33. A slot 37 is formed at a boundary between the front extension section 36 and the first conductor fastening section 33. That is, the front extension section 36 and the first conductor fastening section 33 have a shape in which a base material, forming the planar material 130, is divided by the slot 37.More precisely, the electrical conductors 20 are attached to a central section of a base material, which forms the planar material 130 in the width direction, and a slot 37 is formed on both sides of the electrical conductors 20 from an end edge section to a central section of the base material in a longitudinal direction, whereby the first conductor attachment section 33, the second conductor attachment section 34, the lateral extension section 35 and the front extension section 36 are formed in a base material.

[0062] It is conceivable that the position of the fastening element 40 is the same as the position in the Fig. The conventional example shown in section 8 is shown. In comparison to the one in Fig. In contrast to the conventional planar material shown in Figure 8, the shape of the planar material 130 is modified here, so that when the bending force is applied to the connection-side section 16, it acts in such a way that the electrical conductors 20 and the planar material 30 are hardly separated. This design is described in detail, in addition to Fig. 5, referring to Fig. 6 described. Fig. Figure 6 is a diagram showing a process during the bending of the cable harness 101 equipped with a fastening element according to the second embodiment.

[0063] If, as in Fig. As shown in Figure 6, when the connector C is pulled as in the first embodiment and the connection-side section 16 is bent, the first section 13, which is connected to the connection-side section 16 in the welded area section 12 of the cable harness 110, is bent so that it follows the connection-side section 16. Meanwhile, a second section 14 of the welded area section 12 of the cable harness 110, which is connected to a side opposite the first section 13 to the connection-side section 16, is prevented from following the bend of the connection-side section 16. This is because the fastening element 40 is provided in the respective front extension section 36, which is separated from the first conductor fastening section 33 in the flat material 130 by a slot 37.

[0064] More precisely, the first conductor fastening section 33 in the flat material 130 is separated from the front extension section 36 by the slots 37 in a state in which the fastening elements 40 provided on the front extension section 36 are attached to the fastening object P, thus giving the first conductor fastening section 33 a free end with respect to the second conductor fastening section 34. Therefore, a section of the cable harness 110 located closer to the connector C than to the first sub-section 13 is a free end. Accordingly, when the connector C is pulled and the bending force is applied, the terminal-side section 26 and the first section 23 of the electrical conductors follow the bend. Then, the first conductor fastening section 33 of the flat material 30 also follows the first section 23 of the electrical conductors 20.Accordingly, the first sub-section 13 follows the bend of the connection-side sub-section 16.

[0065] The second conductor fastening section 34 tends to remain in the same position due to the holding force of the fastening element 40, which is provided on the front extension section 36 and extends to the front side of the second conductor fastening section 34 via the lateral extension section 35. At this point, the planar material 30 is bent such that the plane of the main surface 31 of the first conductor fastening section 33 intersects the plane of the main surface 31 of the second conductor fastening section 34. The second section 24 of the electrical conductors 20 is attached to the second conductor fastening section 34, thus also keeping the second section 24 of the electrical conductors 20 in the same position. Accordingly, the holding force of the fastening element 40 prevents the second sub-section 14 from following the bend of the connection-side sub-section 16.

[0066] In the cable harness 1, equipped with a fastening element and having the configuration described above, the first section 13 follows the bend of the connection-side section 16 when the bending force is applied to the connection-side section 16. In contrast, the holding force of the fastening elements 40 prevents the second section 14 from following the bend of the connection-side section 16. In other words, the shape of the flat material 130 and the position of the fastening elements 40 are defined such that a portion of the welded area section 12, where the electrical conductors 20 and the flat material 130 are welded, can follow the bend of the connection-side section 16.

[0067] According to the cable harness 101 equipped with a fastening element, the fastening element 40 can be located at a position offset from the bending position of the electrical conductors 20. Accordingly, one degree of freedom is increased in the positioning of the fastening element 40.

[0068] The slots 37 are formed in the planar material 130, whereby the first conductor fastening section 33, the second conductor fastening section 34 and the front extension sections 36 can be formed in a base material which forms the planar material 130.

[0069] The slots 37 described above must be formed whenever the cable harness 101, equipped with the fastening element, is bent in the state in which the fastening element 40 is attached. In other words, the slots 37 can also be formed only after the cable harness 1, equipped with the fastening element, has been manufactured and only when the cable harness 101, equipped with the fastening element, is bent in the state in which the fastening element 40 is attached. In this case, the slots may only be necessary once the vehicle has reached an assembly plant. However, forming the slots 37 in the vehicle assembly plant in a state where the slots 37 have not yet been formed at all leads to problems. Consequently, it is conceivable to form a perforated line 38 instead of the slots 37, as in the example in Fig. 7 is shown.

[0070] In a flat material 130A of the cable harness 101A equipped with fastening element according to a in Fig. In the modification example shown in Figure 7, the perforated lines 38 are formed in place of the slots 37 at the positions of the slots 37 in the planar material 130 described above. If, in this case, the cable harness 101 equipped with a fastening element is transported to the vehicle assembly plant, and the perforated lines 38 are cut before or during the integration of the cable harness 110A into a vehicle, the slots 37 are formed in the portion of the perforated lines 38.

[0071] In each perforated line 38, several small slots 38a are formed at intervals between them. In particular, there are no restrictions regarding the shape of the perforated line 38, such as the size and spacing of the small slots 38a. For example, it is conceivable that the perforated line 38 is formed in a corresponding shape when it is cut. This means that the perforated line 38 can be designed such that it is cut by the bending force when bending the cable harness 110A, or a process for cutting the perforated line 38 can be provided before the bending process. In the first case, it is preferred that the perforated line 38 is designed such that the force required to cut the perforated line 38 is less than the force that separates the electrical conductors 20 and the planar material 130A from each other.In the latter case, for example, it is preferred that the perforated line 38 is formed by such material properties that it can be cut by hand, so that a worker can separate the flat material with his / her hands.

[0072] According to such a cable harness 101A equipped with a fastening element, the front extension section 36 is separated from the first conductor fastening section 33 by opening the perforated lines 38 to form the slots 37, allowing the first sub-section 13 to follow the bend of the terminal-side sub-section 16. Conversely, the holding force of the fastening elements 40 prevents the second sub-section 14 from following the bend of the terminal-side sub-section 16. According to the cable harness 101A equipped with a fastening element, the movement of the first sub-section 13 can be limited until the perforated lines 38 are opened. Modification example

[0073] In the description of the first embodiment, the fastening element 40 is provided on the lateral extension section 35, although this configuration is not mandatory. For example, it is also conceivable that the fastening element 40 is provided in the second conductor fastening section 34. It is also conceivable, for example, that the fastening element 40 is provided between the electrical conductors 20 and the electrical conductors 20 in the second conductor fastening section 34.

[0074] Even if the fastening element 40 is provided in the lateral extension sections 35, it is not necessary that the lateral extension sections 35 be formed from the same planar material 30 as the second conductor fastening section 34. For example, it is also conceivable that the base material of the planar material forming the lateral extension sections 35 differs from the base material of the planar material forming the second conductor fastening section 34, and that both are joined together.

[0075] In the description of the second embodiment, the fastening element 40 is provided in the front extension sections 36, which are connected to the front side of the lateral extension sections 35, although this configuration is not necessary. For example, it is also conceivable that a base material of the planar material, which is different from the base material of the planar material forming the conductor fastening section 32, is connected to the second conductor fastening section 34, and a fastening element 40 is provided on each of the front extension sections, which are designed to extend forward from the second conductor fastening section 34.

[0076] The embodiments described in the embodiments and the modification examples thereof can be suitably combined as long as they do not contradict each other. For example, in the example shown in the second embodiment, several spot-welded sections W1 are formed, although instead of the spot-welded sections W1, a continuous welded section W2 can also be formed, as described in the first embodiment.

[0077] Although the present invention has been described in detail, the preceding description is in all aspects exemplary and not to be interpreted as limiting. It is therefore understood that numerous modifications and variations can be derived without deviating from the scope of the invention.
