Description

【Technical Field】 , , , , , , 【0005】 【0001】 This invention relates to a power supply device that supplies power to electrical components incorporated in a slide body that slides relative to a vehicle body. 【Background Art】 【0002】 Conventionally, in a slide body that slides relative to a vehicle body, such as a slide door or a slide seat of an automobile, electrical components for improving convenience and comfort have been incorporated. For example, in a slide door of an automobile, electrical components such as a motor for a power window and a speaker for audio are incorporated, and a slide door power supply device for supplying power to these electrical components is provided (see Patent Document 1). 【0003】 Such a slide door power supply device has an electric cable bridged between the vehicle body and the slide door, a slide body side holding portion fixed to the slide door and holding one end side of the electric cable, and a vehicle body side holding portion fixed to the vehicle body and holding the other end side of the electric cable. And since an electric wire connected to an electrical component is connected to the tip of the electric cable fixed to the slide body side holding portion, power can be supplied from the vehicle body to the electrical components incorporated in the slide door. 【0004】 In recent years, due to the tendency for the number of electrical components mounted on vehicles to increase and the provision of storage structures for improving comfort in the vehicle, etc., the space for arranging the vehicle body side holding portion and the slide body side holding portion is limited. Therefore, there is a demand for downsizing of the vehicle body side holding portion and the slide body side holding portion. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】<� Japanese Patent No. 7190084 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0006】 The purpose of this invention is to provide a power supply device that can be made more compact. [Means for solving the problem] 【0007】 This invention relates to a power supply device that supplies power from a vehicle body to an electrical component incorporated in a sliding body that slides relative to the vehicle body, comprising: an electrical cable made of a flexible flat cable and stretched between the vehicle body and the sliding body; a connector connected to the end of the electrical cable, from which an electric wire is led out from the side opposite to the side to which the electrical cable is connected; a sliding body side holding part fixed to the sliding body and holding one end of the electrical cable; and a vehicle body side holding part fixed to the vehicle body and holding the other end of the electrical cable, wherein at least one of the vehicle body side holding part and the sliding body side holding part is provided with a placement part for arranging the connector, and the connector is arranged in the placement part in a direction such that the electric wire is led out along the width direction of the stretching portion of the electrical cable. The electrical cable is constructed by stacking multiple flexible flat cables of the same length in the longitudinal direction, offset from each other in the longitudinal direction. It is characterized by the following: 【0008】 The aforementioned sliding body slides relative to the vehicle body and includes, for example, sliding doors and sliding seats. Note that "sliding relative to the vehicle body" also includes cases where the sliding body slides from the inside to the outside of the vehicle body, or from the outside to the inside. The aforementioned electrical cable includes a configuration consisting of a single flexible flat cable or multiple flexible flat cables stacked on top of each other. 【0009】 This invention makes it possible to make the power supply device more compact. More specifically, the connector to which the electrical cable is connected is positioned in a mounting section provided on at least one of the vehicle body-side mounting section and the slide body-side mounting section. This allows for a reduction in the length of at least one of the vehicle body-side mounting section and the slide body-side mounting section in the thickness direction of the electrical cable, which is composed of a flexible flat cable. Furthermore, since the wires connected to the electrical components are led out along the width direction rather than the thickness direction when the connector is positioned in the mounting section, the protrusion of the wires in the thickness direction can be suppressed. In this way, the vehicle body-side mounting section and the slide body-side mounting section can be made more compact in the thickness direction, and the protrusion of the wires in the thickness direction can be suppressed. Therefore, the vehicle body-side mounting section and the slide body-side mounting section can be installed even in locations where the space for arranging them is limited. 【0010】 Furthermore, the electrical cable is constructed by stacking multiple flexible flat cables, each having the same length in the longitudinal direction, with a slight offset in the longitudinal direction. This allows for the standardization of the lengths of the multiple flexible flat cables that make up an electrical cable, eliminating the need to prepare multiple flexible flat cables of different lengths. Therefore, the work process for connecting each flexible flat cable to a connector can be simplified. Furthermore, when bending one end of a flexible flat cable, all flexible flat cables can be bent at the same position, further simplifying the work process. 【0011】 In one embodiment of this invention, the arrangement portion may be provided with a housing portion that accommodates a bent portion obtained by bending one end of the electrical cable, and also guides the end of the electrical cable beyond the bent portion toward the side from which the electric wire is led out. 【0012】 This invention allows one end of an electrical cable, which is made of a flexible flat cable, to be bent toward the placement section and housed in the housing section. This prevents the bent portion of the electrical cable from bulging excessively in the longitudinal direction of the cable, thus making the housing section more compact. Consequently, at least one of the vehicle body-side holding section and the slide body-side holding section can be made more compact. Furthermore, by bending one end of the electrical cable and housing it in the housing section, the bent state of the electrical cable can be maintained, and one end of the electrical cable can be protected. 【0013】 In another aspect of this invention, the direction in which the slide body slides relative to the vehicle body is defined as the sliding direction, and a shape restricting portion is provided on one side of the sliding direction in at least one of the vehicle body-side holding portion and the slide body-side holding portion to restrict the bent shape of the electrical cable. 【0014】 This invention allows for a simple configuration to guide a bent electrical cable along a shape-restricting section when the cable is under strong tension. This prevents the electrical cable from being damaged by sharp corners. 【0015】 Furthermore, if the wires leading out from the connectors placed in the mounting section were oriented in the thickness direction, there was a risk of interference between the bent electrical cable and the wires. Therefore, it was necessary to provide a protective member between the electrical cable and the wires. However, since the wires leading out from the connectors placed in the mounting section are oriented in the width direction, there is no risk of interference between the bent electrical cable and the wires, and it is not necessary to provide a protective member between the wires and the electrical cable. Therefore, it is possible to make at least one of the vehicle body-side holding part and the slide body-side holding part more compact in the thickness direction, while also protecting the wires. 【0016】 In another aspect of this invention, a fixing portion for fixing the electrical cable may be provided between the shape restricting portion and the arrangement portion. This invention makes it possible to suppress the separation of the electrical cable in the thickness direction from at least one of the vehicle body-side holding portion and the slide body-side holding portion where the arrangement portion is provided, between the shape-regulating portion and the arrangement portion. As a result, at least one of the vehicle body-side holding portion and the slide body-side holding portion on which the electrical cable is routed can be made more compact in the thickness direction. 【0017】 In another aspect of this invention, the arrangement portion may be provided with an extended fixing portion that extends in the width direction and fixes the connecting body arranged in the arrangement portion. According to the present invention, since the connector is fixed in a state of being disposed in the disposing portion, it is possible to regulate the unintentional movement of the connector. That is, since the movement of the connector in the thickness direction is regulated, it is not necessary to provide an excess length along the thickness direction in the disposing portion, and the length along the thickness direction of the disposing portion can be shortened. Therefore, at least one of the vehicle body side holding portion and the slide body side holding portion can be made more compact. 【0018】 As another aspect of the present invention, the direction in which the slide body is slid with respect to the vehicle body is defined as the slide direction, and the extending fixing portion may be provided at an end portion of the disposing portion in the slide direction. According to the present invention, it is possible to prevent the connector from protruding toward at least one of the slide directions. Therefore, it is possible to achieve the compactification of at least one of the vehicle body side holding portion and the slide body side holding portion along the slide direction. 【Advantages of the Invention】 【0019】 According to the present invention, it is possible to provide a power feeding device that can be made compact. 【Brief Description of the Drawings】 【0020】 [Figure 1] Schematic perspective view of a slide door power feeding device.

[Modes for carrying out the invention] 【0021】 In the following, a sliding door power supply device 1, which supplies power from the vehicle body 100 to electrical components incorporated in a sliding door 200 that slides relative to the vehicle body 100, will be described in detail with reference to Figures 1 to 10. 【0022】 Figure 1 shows a schematic perspective view of the sliding door power supply device 1, Figure 2 shows an explanatory diagram of the electrical cable 2, and Figure 3 shows an explanatory diagram of the connector unit 5 connected to the end of the electrical cable 2. Figure 4 shows an enlarged schematic perspective view of the sliding door side retaining part 4 with the connector case 50 to which one end of the electrical cable 2 is connected. Figures 5 to 7 show explanatory diagrams of the sliding door side retaining part 4, and Figures 8 to 10 show explanatory diagrams of the sliding door side retaining part 4 with the connector case 50 to which one end of the electrical cable 2 is connected. 【0023】 Figures 2, 3, and 5 through 10 will be described in detail. Figure 2(a) shows a schematic plan view of the electrical cable 2, and Figure 2(b) shows a schematic front view of the flexible flat cable 21 viewed from the thickness direction. Figure 3(a) shows a schematic perspective view of the connector case 50, and Figure 3(b) shows a schematic perspective view illustrating the process of manufacturing the connector unit 5 by stacking the connector cases 50. 【0024】 Figure 5(a) shows a schematic perspective view of the sliding door side retaining part 4, and Figure 5(b) shows a schematic plan view of the sliding door side retaining part 4. Figure 6(a) shows a schematic front view of the sliding door side retaining part 4 as seen from the outer side WO, Figure 6(b) shows an enlarged view of part a in Figure 6(a), and Figure 6(c) shows an enlarged view of part b in Figure 6(a). Figure 7(a) shows a cross-sectional view taken along arrow AA in Figure 5(b), and Figure 7(b) shows an enlarged schematic cross-sectional view of the cable housing part 47 in Figure 7(a). Note that Figure 7(b) is a schematic cross-sectional view of the area corresponding to part b in Figure 6(a). 【0025】 Figure 8 shows a schematic front view of the sliding door side retaining part 4 with the connector case 50 to which one end of the electrical cable 2 is connected. Figure 9(a) shows a schematic plan view of the sliding door side retaining part 4 with the connector case 50 to which one end of the electrical cable 2 is connected, and Figure 9(b) shows a cross-sectional view taken along the arrow BB in Figure 8. Figure 10(a) shows a cross-sectional view taken along the arrow CC in Figure 9(a), and Figure 10(b) shows an enlarged view of part c in Figure 10(a). 【0026】 In Figure 1, the vertical direction is defined as the height direction H, and the longitudinal direction of the vehicle body 100 and the sliding door 200, that is, the direction in which the sliding door 200 slides relative to the vehicle body 100, is defined as the sliding direction L. Note that the sliding direction L and the height direction H are perpendicular to each other. Furthermore, the direction perpendicular to the sliding direction L and the height direction H is defined as the width direction W. 【0027】 Furthermore, in Figure 1, the upper side along the height direction H is designated as upper HU, and the lower side along the height direction H is designated as lower HD. Similarly, the right side along the sliding direction L is designated as front LF, the left side along the sliding direction L is designated as rear LB, the right side along the width direction W is designated as outward WO, and the left side along the width direction W is designated as inward WI. The direction defined in Figure 1 is the same in Figures 4 through 10. 【0028】 As shown in Figure 1, the sliding door power supply device 1 comprises an electrical cable 2, a vehicle body-side retaining part 3, and a sliding door-side retaining part 4. Connector units 5 of the same specifications are connected to both ends of the electrical cable 2. The connector units 5 are fixed to the vehicle body-side retaining part 3 and the sliding door-side retaining part 4 via fasteners 7. Furthermore, on the side of the connector unit 5 opposite to the side to which the electrical cable 2 is connected, a bundle of wires 6 is connected, which is electrically connected to electrical components incorporated into the vehicle body 100 and the sliding door 200 (see Figure 4). 【0029】 The electrical cable 2 is stretched between the vehicle body 100 and the sliding door 200. As shown in Figures 2(a) and 2(b), this electrical cable 2 is made up of multiple flexible flat cables 21 that are overlapped and offset in the longitudinal direction. 【0030】 The flexible flat cable 21 has a structure in which parallel strip-shaped conductive materials are sandwiched between sheet-shaped insulators. As shown in Figure 2(a), connector cases 50 that constitute the connector unit 5 are connected to both ends of the flexible flat cable 21. 【0031】 Furthermore, as shown in Figure 2(b), the flexible flat cable 21 has a bent portion 211 at one end (the side of the sliding door side holding portion 4) which is bent in the direction perpendicular to the longitudinal direction of the flexible flat cable 21, in the direction of the surface width. As a result, one end of the electrical cable 2 along the longitudinal direction is redirected to extend in the direction of the surface width of the flexible flat cable 21 at the connection point between the vehicle body side holding portion 3 and the sliding door side holding portion 4. 【0032】 The electrical cable 2 is made up of flexible flat cables 21 of equal length along their longitudinal direction, which are offset along their longitudinal direction and overlapped in the thickness direction to form a bundle. This bundle of flexible flat cables 21, which are overlapped in the thickness direction, is covered by a flexible cable sheath member 22. 【0033】 In this embodiment, the electrical cable 2 is constructed by stacking eight flexible flat cables 21. Of the eight stacked flexible flat cables 21, the flexible flat cable 21 located on the outermost side in the thickness direction (the lower side in Figure 2(a)) is referred to as flexible flat cable 21a. The flexible flat cable 21 stacked on the other side in the thickness direction of flexible flat cable 21a (the upper side in Figure 2(a)) is referred to as flexible flat cable 21b (see Figure 2(a)). 【0034】 The eight overlapping flexible flat cables 21 have the same length along their longitudinal direction. Therefore, the connector cases 50 (connector case 50a) connected to both ends of the flexible flat cable 21a are positioned on one side along the longitudinal direction of the connector cases 50 (connector case 50b) connected to both ends of the flexible flat cable 21b (see Figure 2(a)). 【0035】 The connector unit 5 connected to both ends of the electrical cable 2 is constructed by stacking multiple connector cases 50. The number of connector cases 50 can be freely changed according to the specifications of the sliding door 200. Specifically, it can be freely changed according to the number of flexible flat cables 21 required. In this embodiment, the connector unit 5 is constructed by stacking nine connector cases 50. 【0036】 As shown in Figure 3, the connector case 50 has a main plate portion 51 which is a roughly rectangular flat plate, and a pair of side plate portions 52 which are erected from both ends of the short side of the main plate portion 51. In the connector case 50, the space enclosed by the pair of side plate portions 52 and the main plate portion 51 is defined as the terminal housing portion 5C. Connection terminals 53 are housed in the terminal housing portion 5C according to the circuits corresponding to the electrical components. 【0037】 The connecting terminal 53 housed in the terminal housing section 5C has a piercing portion 531 provided on one side in the long-side direction of the main plate portion 51 and a barrel portion 532 provided on the other side in the long-side direction. 【0038】 The piercing portion 531 is a so-called piercing terminal, and by fastening the flexible flat cable 21 to it, the flexible flat cable 21 and the connection terminal 53 can be electrically connected. The barrel section 532 is a so-called closed barrel, and by crimping the wire 61 that is connected to the electrical components, the wire 61 and the connection terminal 53 can be electrically connected. In this way, the flexible flat cable 21 and the wire 61 are electrically connected via the connection terminal 53. 【0039】 The main plate portion 51 is formed in a substantially rectangular plate shape. Three partition plates 511 are provided on the inner wall surface of the main plate portion 51, arranged at predetermined intervals along the short side in the short-side direction. The partition plates 511 are formed with the highest point in the central portion along the long side in the long-side direction, and an engaging piece 512 is provided at the leading edge of the partition plate 511 extending toward the other side in the long-side direction. 【0040】 Furthermore, the outer wall surface of the main plate portion 51 is provided with a vertical plate extending in the direction of the short side in the central part in the direction of the long side. This vertical plate is formed to have a constant height, and its leading edge is provided with an engaging piece 513 that is configured to be able to lock with an engaging piece 512 provided on the adjacent connector case 50 (see Figure 2). 【0041】 The side plate portion 52 is a roughly plate-shaped side wall erected from both outer edges in the short-side direction of the main plate portion 51. More specifically, the side plate portion 52 has a first side plate portion 521 provided from one outer edge in the long-side direction of the main plate portion 51 to the central portion, and a second side plate portion 522 provided from the first side plate portion 521 to the other outer edge in the long-side direction. 【0042】 The first side plate portion 521 is a side wall erected from one outer edge in the long-side direction of the main plate portion 51. The second side plate portion 522 is a side wall portion having the same plate thickness as the first side plate portion 521 and is positioned further inward in the short-side direction than the first side plate portion 521. That is, the outer edge in the short-side direction of the main plate portion 51 is recessed further inward in the short-side direction on the other side in the long-side direction than on the one side in the long-side direction. For this reason, a step portion 523 is formed between the outer wall of the first side plate portion 521 and the outer wall of the second side plate portion 522. A locking groove 524 is provided in this step portion 523, which is formed by recessing the outer wall of the second side plate portion 522. This locking groove 524 extends from the other side in the long-side direction of the main plate portion 51 toward the first side plate portion 521. 【0043】 The tip of the second side plate portion 522 is provided with a hook-shaped locking portion 525 that protrudes in the direction in which the side plate portion 52 is erected. The locking portion 525 is configured to be able to lock into a locking groove 524 in another stacked connector case 50. The outer wall of the locking portion 525 is flush with the outer wall of the first side plate portion 521. 【0044】 Furthermore, the first side plate portion 521 and the second side plate portion 522 are each provided with a projection 526 that protrudes outward in the short-side direction. The spacing between the projections 526 along the long-side direction is equal to the width of the band portion 71, which will be described later. 【0045】 The method for stacking the connector cases 50 configured in this way will now be explained. First, the flexible flat cable 21 and the electric wire 61 are connected to the connection terminals 53 housed in the terminal housing section 5C. Then, as shown in Figure 3, the connector cases 50 can be stacked by sliding them along the longitudinal direction relative to adjacent connector cases 50. At this time, the engaging piece 512 and the engaged portion 513 are locked together, and the locking portion 525 on the other side is locked together with the locking groove 524 on the other side. 【0046】 As a result, on one side of the long side of the connector unit 5, which is formed by stacking multiple connector cases 50, multiple flexible flat cables 21 connected to each connector case 50 can be stacked. On the other side of the long side of the connector unit 5, the wires 61 extending from each connection terminal 53 can be gathered and bundled together to form a wire bundle 6 (see Figure 2(a)). 【0047】 Here, of the wire bundles 6, the wire bundle 6 that is electrically connected to the electrical equipment incorporated into the vehicle body 100 is designated as the vehicle body side wire 6a, and the wire bundle 6 that is electrically connected to the electrical equipment incorporated into the sliding door 200 is designated as the door side wire 6b. 【0048】 The vehicle-side retaining part 3 holds one end of the electrical cable 2 and is fixed to the vehicle body 100. More specifically, the vehicle-side retaining part 3 is fixed to the floor panel of the vehicle body 100. A connector unit 5 for connecting the electrical cable 2 and the vehicle-side wire 6a is assembled to the vehicle-side retaining part 3. 【0049】 As shown in Figure 4, the sliding door-side retaining part 4 holds the other end of the electrical cable 2 and is fixed to the sliding door 200. More specifically, the sliding door-side retaining part 4 is fixed to the inner panel of the sliding door 200. A connector unit 5 connecting the electrical cable 2 and the door-side wire 6b is fixed to the sliding door-side retaining part 4 with a fastener 7. 【0050】 Here, the fastening device 7 is a so-called fastening band, and comprises a band portion 71 made of a long, strip-shaped body, and a buckle portion 72 to which the base end of the band portion 71 is connected, and which allows the tip of the band portion 71 to be inserted and securely fastened in an annular shape. 【0051】 The sliding door side retaining part 4 will be described in detail below. As shown in Figures 5(a) and 5(b), the sliding door side retaining portion 4 is a long block body in plan view, with the front side LF end formed in an arc shape. This sliding door side retaining portion 4 is integrally composed of a tip portion 41 located on the front side LF, an intermediate portion 42 located on the rear side LB of the tip portion 41, and a base portion 43 located on the rear side LB of the intermediate portion 42. 【0052】 The tip portion 41 is formed in a semi-cylindrical shape with a base that is approximately semicircular in plan view. The base of this tip portion 41 has a diameter that is slightly longer than the short side of the main plate portion 51. In addition, the height of the tip portion 41 is longer than the width of the flexible flat cable 21. 【0053】 The intermediate section 42 is a rectangular prism in its base view, having a short side with a width equal to the diameter of the tip section 41 and a long side that is approximately three times the diameter of the base of the tip section 41. The height of this intermediate section 42 is equal to the height of the tip section 41. As shown in Figures 5 and 6, the intermediate section 42 is provided with a pair of bolt fixing parts 44 for bolting it to the inner panel of the sliding door 200, and two through holes 45 that penetrate the intermediate section 42 in the height direction H. 【0054】 The bolt fixing portion 44 is a flat plate that rises from the intermediate portion 42 along the height direction H, and is provided with bolt holes 441 that penetrate in the thickness direction at predetermined locations. By aligning these bolt holes 441 with predetermined locations on the inner panel of the sliding door 200 and inserting bolts into the bolt holes 441, the sliding door side holding portion 4 can be fixed to the sliding door 200. 【0055】 The bolt fixing portion 44 configured in this way is provided on the outer side WO and the inner side WI of the central portion in the sliding direction L of the intermediate portion 42. Here, the bolt fixing portion 44 provided on the outer side WO is referred to as the first fixing portion 44a, and the bolt fixing portion 44 provided on the inner side WI is referred to as the second fixing portion 44b. 【0056】 As shown in Figures 5(b) and 6, the first fixing portion 44a extends downward from the end of the outer WO in the intermediate portion 42 toward the lower HD. This first fixing portion 44a protrudes slightly outward from the outer wall of the outer WO in the intermediate portion 42. The second fixing portion 44b extends downward from the end of the outer WO in the intermediate portion 42 toward the lower HD. The second fixing portion 44b is flush with the outer wall of the inner WI in the intermediate portion 42. 【0057】 The through-hole 45 is formed by penetrating the vicinity of the end of the outer WO in the intermediate portion 42 along the height direction H. The length of the through-hole 45 along the sliding direction L is slightly longer than the width of the band portion 71 and shorter than the width of the buckle portion 72. Therefore, the band portion 71 can be inserted through the through-hole 45. Two such through-holes 45 are provided at both ends of the second fixing portion 44b along the sliding direction L. 【0058】 As shown in Figures 5 and 6, the base end portion 43 is a rectangular prism in a bottom view, having a short side with a width equal to the diameter of the tip portion 41 and a long side longer than the length along the stacking direction of the connector unit 5 formed by stacking connector cases 50. The height of this intermediate portion 42 is equal to the height of the tip portion 41. More specifically, the length of the base end portion 43 along the sliding direction L is approximately equal to the length along the stacking direction of the connector unit 5 plus the length along the stacking direction when four connector cases 50 are stacked. 【0059】 As shown in Figures 5 and 6, an extension portion 46 is provided on the upper surface of the base portion 43 configured in this way. In addition, as shown in Figures 6 and 7, a plurality of cable housing portions 47 are provided on the outer side WO of the base portion 43, through which cables are inserted inward. 【0060】 The extension section 46 is a hollow, frame-like body that is rectangular in plan view and penetrates along the width direction W, extending from the rear end LB at the base end 43 toward the upper end HU. More specifically, the extension section 46 consists of a first extension wall 461 erected from the base end 43 toward the upper end HU, a second extension wall 462, an upper end connecting wall 463 connecting the first extension wall 461 and the second extension wall 462, a central connecting wall 464, and an inner connecting wall 465. 【0061】 The first extension wall 461 is a flat plate erected from the end of the rear side LB at the base end 43 toward the upper side HU, and has a height slightly longer than the long side of the main plate portion 51. The length of the first extension wall 461 along the width direction W is approximately the same as the short side of the main plate portion 51. The thickness of the first extension wall 461 is equal to the length from the first side plate portion 521 to the tip of the locking portion 525. 【0062】 The second extension wall 462 is a flat plate with substantially the same shape as the first extension wall 461, and is erected at a distance from the first extension wall 461 that is substantially equal to the width of the band portion 71. In the upper HU of the second extension wall 462 configured in this way, a case locking groove 466 is formed, recessed inward in the width direction W, so that the locking portion 525 can be locked into it. 【0063】 The upper end connecting wall 463 is a flat plate that connects the upper ends of the first extension wall 461 and the second extension wall 462 in the sliding direction L. The central connecting wall 464 is a flat plate that connects the central portions of the first extension wall 461 and the second extension wall 462 in the sliding direction L at the lower end portion of the case locking groove 466. The main surfaces of the upper end connecting wall 463 and the central connecting wall 464 are parallel to the upper surface of the sliding door side holding portion 4. 【0064】 As shown in Figures 6(b) and 7, the inner connecting wall 465 is a flat plate that connects the first extension wall 461 and the second extension wall 462 so as to straddle the inner side WI. More specifically, the inner connecting wall 465 is a flat plate having a main surface along the sliding direction L and the height direction H, and connects the upper end connecting wall 463 slightly below HD along the sliding direction L. A gap approximately equal to the width of the band portion 71 is provided between the lower end of the inner connecting wall 465 and the central connecting wall 464. 【0065】 In other words, communication holes are formed in the upper end and central portions of the extension portion 46, connecting along the width direction W, so that the band portion 71 can be inserted. Here, the communication hole in the upper HU is designated as the first communication hole 467, and the communication hole in the central portion is designated as the second communication hole 468. 【0066】 As shown in Figures 6(c) and 7, the cable housing portion 47 is a slit formed by cutting out the base end portion 43 so as to straddle the side surface of the outer WO of the base end portion 43 and the upper surface of the upper HU. More specifically, the cable housing portion 47 is a slit formed by cutting out the upper surface of the upper HU of the base end portion 43 toward the lower HD, and has a housing portion 471, a protruding portion 472 provided at the upper end of the housing portion 471, and a support portion 473 provided at the central part of the housing portion 471 in the height direction H. 【0067】 The housing portion 471 is a slit cut out in plan view from the end of the outer WO of the base portion 43 to near the end of the inner WI, forming a housing space S inside the base portion 43 that can accommodate the bent portion 211 (see Figure 7(b)). The length of this housing portion 471 along the width direction W and the height direction H is sufficiently longer than the width of the flexible flat cable 21. Also, the length of the housing portion 471 along the sliding direction L is about four times the plate thickness of the flexible flat cable 21. 【0068】 The projection 472 protrudes from the upper end of the front side LF of the housing 471 toward the rear side LB. The outer end WO of this projection 472 is arc-shaped in plan view, moving toward the inward side WI as it moves toward the rear side LB (see Figure 5(b)). The length of the projection 472 along the sliding direction L is slightly less than twice the thickness of the flexible flat cable 21. That is, an opening is formed on the rear side LB of the projection 472, having a length of approximately twice the thickness of the flexible flat cable 21. 【0069】 The support portion 473 is a projection that extends from the end face of the front side LF toward the rear side LB in the central part of the height direction H of the housing portion 471, and has the same shape as the projection portion 472. The cable housing section 47 has an insertion opening 474 formed on the side surface of the outer WO at the base end 43 and an outlet opening 475 formed on the upper surface of the upper HU at the base end 43 (see Figures 5(b) and 6). 【0070】 The cable housing sections 47 configured in this way are arranged in eight equal intervals along the sliding direction L, corresponding to the number of flexible flat cables 21. Furthermore, the distance between adjacent cable housing sections 47 is approximately equal to the height of the stacked connector cases 50. 【0071】 Next, we will briefly explain how to secure the electrical cable 2, to which the connector unit 5 is connected, to the sliding door side retaining part 4 configured in this way. As shown in Figures 8 to 10, the bent portion 211 is inserted through each insertion opening 474 such that the tip of the bent portion 211 emerges from each outlet 475 provided along the sliding direction L. This allows the bent portion 211 to be housed in the storage space S. 【0072】 Here, as shown in Figures 9 and 10, the bent portion 211 housed in the housing space S is supported by the protruding portion 472 and the support portion 473, so that the flexible flat cable 21 can be reliably guided out from the outlet 475 to the upper HU, and the bent shape of the bent portion 211 can be maintained. In addition, since the outer side WO of the protruding portion 472 and the support portion 473 is arc-shaped, the flexible flat cable 21 can be easily housed from the insertion opening 474 without deforming the bent portion 211. 【0073】 Furthermore, when the bent portion 211 is housed in the cable housing portion 47, the tip end of the bent portion 211 leads out from the outlet 475 towards the upper HU. Therefore, the connector unit 5 to which the tip of the bent portion 211 is connected can be placed on the upper surface of the base end portion 43 so that the door-side electric wire 6b leads out towards the upper HU. 【0074】 At this time, the connector unit 5 can be locked and fixed to the extension portion 46 by engaging the locking portion 525 of the connector case 50 located on the rear side LB with the case locking groove 466. In this state, the band portion 71 is inserted through the first communication hole 467, wrapped around between the protruding pieces 526 to form a ring, and locked and fixed to the buckle portion 72. As a result, the connector unit 5 is securely fixed to the extension portion 46 via the fastener 7 (see Figure 8). 【0075】 Similarly, the door-side wire 6b, which is led out from the connector unit 5 toward the upper HU, is curved toward the upper HU of the extension portion 46, and the band portion 71, which is inserted through the second communication hole 468, is wrapped around the outer surface of the door-side wire 6b and secured to the buckle portion 72. This ensures that the door-side wire 6b is securely fixed to the extension portion 46 (see Figure 8). 【0076】 Thus, the connector unit 5 is fixed to the upper HU at the base end 43. In other words, the sliding door side retaining portion 4 can be shaped to match the width (length in the width direction W) of the connector unit 5 located at the base end 43, making the sliding door side retaining portion 4 compact in the width direction W. Therefore, the sliding door side retaining portion 4 can be installed even in locations where the space for installing the sliding door side retaining portion 4 is limited. 【0077】 Next, the electrical cable 2 is placed along the intermediate section 42, and the band section 71, which has been inserted through the through hole 45, is wrapped around the cable sheath member 22 and inserted into the buckle section 72 to lock and secure it. This allows the electrical cable 2 to be fixed to the intermediate section 42 via the fastener 7 between the tip section 41 and the base section 43 (see Figure 8). In other words, it is possible to prevent the electrical cable 2 from separating from the outer side WO of the intermediate section 42. 【0078】 Finally, the electrical cable 2 is bolted to the inner panel of the sliding door 200 via the bolt fixing part 44, and the vehicle body side holding part 3, to which the other end of the electrical cable 2 is connected, is fixed to the floor panel of the vehicle body 100. This allows the electrical cable 2 to be stretched between the vehicle body 100 and the sliding door 200. 【0079】 As described above, the electrical cable 2 stretched between the vehicle body 100 and the sliding door 200 is flexible and can follow the sliding movement of the sliding door 200 relative to the vehicle body 100. Here, if the sliding door side retaining part 4 is located on the forward side LF of the vehicle body side retaining part 3 (see Figure 1), the electrical cable 2 will be wound back. In this case, since the electrical cable 2 is wound back along the tip 41 which is arc-shaped in plan view, the electrical cable 2 will not come into contact with the sliding door side retaining part 4 at an angle, and damage to the electrical cable 2 can be prevented. 【0080】 Furthermore, if the sliding door side retaining part 4 is located on the forward side LF of the vehicle body side retaining part 3, the electrical cable 2 will be routed on the inner side WI of the sliding door side retaining part 4 (see Figure 1). If the door side wire 6b, which is led out from the connector unit 5 located at the base end 43, is led out toward the inner side WI, there is a risk of interference between the door side wire 6b and the electrical cable 2. For this reason, it was necessary to provide a protective member between the door side wire 6b and the electrical cable 2 in the sliding door side retaining part 4. However, since the door side wire 6b, which is led out from the connector unit 5 located at the base end 43, is led out in the height direction H, there is no risk of interference with the bent electrical cable 2. Therefore, there is no need to provide a protective member between the door side wire 6b and the electrical cable 2, and the sliding door side retaining part 4 can be made more compact in the width direction W. 【0081】 The sliding door power supply device 1 configured in this way supplies power from the vehicle body 100 to electrical components incorporated in the sliding door 200, which slides relative to the vehicle body 100. This sliding door power supply device 1 is composed of a flexible flat cable 21 and includes an electrical cable 2 stretched between the vehicle body 100 and the sliding door 200, a connector unit 5 connected to the end of the electrical cable 2 and from which the door-side wire 6b is led out from the side opposite to the side to which the electrical cable 2 is connected, a sliding door side holding part 4 fixed to the sliding door 200 and holding one end of the electrical cable 2, and a vehicle body side holding part 3 fixed to the vehicle body 100 and holding the other end of the electrical cable 2. A base end portion 43 is provided on the sliding door side holding part 4 for positioning the connector unit 5, and the connector unit 5 is positioned on the base end portion 43 in a direction in which the door-side wire 6b is led out along the width direction (height direction H) of the stretched portion of the electrical cable 2. 【0082】 This makes it possible to make the sliding door power supply device 1 more compact. More specifically, the connector unit 5 to which the electrical cable 2 is connected is positioned at the base end 43 provided on the sliding door side retaining part 4. This shortens the length of the sliding door side retaining part 4 in the width direction W of the electrical cable 2, which is composed of a flexible flat cable 21. In addition, the door side wire 6b connected to the electrical equipment is led out along the height direction H rather than the width direction W when the connector unit 5 is positioned at the base end 43, thus suppressing protrusion in the width direction W. In this way, the sliding door side retaining part 4 can be made more compact in the width direction W, and the protrusion of the door side wire 6b in the width direction W can be suppressed. Therefore, the sliding door side retaining part 4 can be installed even in locations where the space for installing the sliding door side retaining part 4 is limited. 【0083】 Furthermore, the base end portion 43 is provided with a cable housing portion 47 that accommodates a bent portion (bent portion 211) obtained by bending one end of the electrical cable 2, and also guides the end of the electrical cable 2 beyond the bent portion to the upper HU, which is the side from which the door-side electric wire 6b is led out. 【0084】 In the sliding door power supply device 1 configured in this way, one end of the electrical cable 2, which is made of a flexible flat cable 21, can be bent toward the base end 43 and housed in the cable housing section 47. This prevents the bent portion of the electrical cable 2 from bulging excessively in the sliding direction L, and makes the cable housing section 47 more compact. Therefore, the sliding door side holding section 4 can be made more compact. In addition, by bending one end of the electrical cable 2 and housing it in the cable housing section 47, the bent state of the electrical cable 2 can be maintained, and one end of the electrical cable 2 can be protected. 【0085】 Furthermore, the direction in which the sliding door 200 slides relative to the vehicle body 100 is defined as the sliding direction L, and a tip portion 41 that restricts the bending shape of the electrical cable 2 is provided on one side of the sliding door side holding portion 4 in the sliding direction L. 【0086】 This allows the bent electrical cable 2 to follow the tip 41 even when it is pulled strongly, thus preventing the electrical cable 2 from being damaged by contact with a corner, while maintaining a simple configuration. 【0087】 Previously, if the door-side wire 6b, which is led out from the connector unit 5 located at the base end 43, were led out in the width direction W, there was a risk of interference between the door-side wire 6b and the electrical cable 2, requiring the provision of a protective member between the electrical cable 2 and the door-side wire 6b. However, since the door-side wire 6b, which is led out from the connector unit 5 located at the base end 43, is led out in the height direction H, there is no risk of interference with the bent electrical cable 2, and therefore, there is no need to provide a protective member between the door-side wire 6b and the electrical cable 2. As a result, at least one of the vehicle body-side retaining part 3 and the sliding door-side retaining part 4 can be made more compact in the width direction W, and the door-side wire 6b can be protected. 【0088】 Furthermore, an intermediate section 42 is provided between the tip 41 and base 43 of the sliding door side retaining section 4, for securing the electrical cable 2 via a fastener 7 inserted through a through hole 45. This prevents the electrical cable 2 from separating from the sliding door side retaining section 4 in the width direction W between the tip 41 and base 43. Therefore, the sliding door side retaining section 4, through which the electrical cable 2 is routed, can be made more compact in the width direction W. 【0089】 Furthermore, the base end portion 43 is provided with an extension portion 46 that extends in the height direction H and fixes the connector unit 5 that is positioned on the base end portion 43. This allows the connector unit 5 to be fixed in place on the base end portion 43, thereby restricting unintended movement of the connector unit 5. In other words, since the movement of the connector unit 5 in the width direction W is restricted, there is no need to provide an excess length in the width direction W of the base end portion 43, and the length of the base end portion 43 in the width direction W can be shortened. Therefore, the sliding door side holding portion 4 can be made more compact in the width direction W. 【0090】 Furthermore, the sliding direction L is defined as the direction in which the sliding door 200 slides relative to the vehicle body 100, and the extended portion 46 is provided at the end of the base portion 43 in the sliding direction L. This prevents the connector unit 5 from protruding toward the rear side LB. Therefore, the sliding door side holding portion 4 can be made more compact along the sliding direction L. 【0091】 Furthermore, the electrical cable 2 is constructed by stacking multiple flexible flat cables 21, each having the same length in the longitudinal direction, with a longitudinal offset. Therefore, the lengths of the multiple flexible flat cables 21 constituting the electrical cable 2 can be standardized, eliminating the need to prepare multiple flexible flat cables 21 of different lengths. Consequently, the process of connecting each flexible flat cable 21 to the connector unit 5 can be simplified. Additionally, when bending one end of a flexible flat cable 21, all flexible flat cables 21 can be bent at the same position, further simplifying the work process. 【0092】 In the correspondence between the structure of this invention and the above-described embodiment, the vehicle body of this invention corresponds to the vehicle body 100, The sliding body is compatible with the 200 sliding door. The power supply device corresponds to the sliding door power supply device 1. The flexible flat cable is compatible with the flexible flat cable 21. The electrical cable corresponds to electrical cable 2. The wire corresponds to the door-side wire 6b. The connector corresponds to connector unit 5, The sliding body side retaining part corresponds to the sliding door side retaining part 4. The vehicle body side retaining part corresponds to the vehicle body side retaining part 3, The arrangement part corresponds to the base end 43, The width direction corresponds to the height direction H. The housing section corresponds to the cable housing section 47. The sliding direction corresponds to the sliding direction L. The shape-regulating section corresponds to the tip section 41, The fixing part corresponds to the intermediate part 42, The extended fixing portion corresponds to the extended portion 46, but this invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained. 【0093】 For example, in this embodiment, the base end portion 43 is provided on the sliding door side retaining portion 4, but the vehicle body side retaining portion 3 may have the same configuration as the sliding door side retaining portion 4. Also, both the vehicle body side retaining portion 3 and the sliding door side retaining portion 4 may have the same configuration. Furthermore, the connector unit 5 is located on the upper HU of the base end portion 43, but it may also be located on the lower HD. 【0094】 Furthermore, in this embodiment, the sliding door power supply device 1 is attached to a sliding door 200 that slides relative to the vehicle body 100, but it is not limited to this as long as it can slide relative to the vehicle body 100. For example, the sliding door power supply device 1 may be attached to a sliding seat that slides relative to the vehicle body 100. Note that sliding relative to the vehicle body 100 includes sliding from the inside to the outside of the vehicle body 100, or from the outside to the inside. 【0095】 In this embodiment, the electrical cable 2 is configured by overlapping multiple flexible flat cables 21, but as described above, the number of flexible flat cables 21 can be changed as appropriate. For example, the number of flexible flat cables 21 may be just one. In this case, the length of the base end 43 along the sliding direction L can also be changed as appropriate.
