The front and rear correspond to the front and rear direction of the vehicle. The case 2 includes a vertical substrate portion 8, a lower horizontal wall portion 9 as a peripheral wall around the substrate portion 8, a front curved wall portion 10, and an upper horizontal short wall portion 11. And a curved wall 12 in the latter half following the upper wall 11.
A narrow mouth portion 13 for leading out a harness is provided on the upper wall portion 11, and one of the wire harnesses 6 is fixed by a fixing portion 14 near the mouth portion 13. The wire harness led out from the opening 13 is connected to a wire harness on the slide door side and an auxiliary device (not shown) by a connector 15. The case 2 is fixed to an inner panel of a slide door (not shown) by fixing means (not shown) such as bolts and locking clips.
The cover 3 is provided in parallel with the substrate 8 in a plate shape, and is fixed to the peripheral walls 10 to 12 by locking means (not shown) such as locking frame pieces and engaging projections. The lower end of the cover 3 is located slightly above the lower wall 9 of the case 2, and a horizontally long slit-shaped opening 16 is formed between the cover 3 and the lower wall 9. The other is drawn out and connected to a wire harness (not shown) on the vehicle body side by a connector 18 via a harness fixing portion (fixing tool) 17 on the vehicle body (fixed structure) side.
The harness fixing portion 17 may have a structure that supports the wire harness 6 so as to be rotatable in the circumferential direction. In addition, a rectangular tubular long or arcuate auxiliary protector extending between the slide door and the vehicle body is provided in place of the harness fixing part 17, and the auxiliary protector is mounted on the vehicle width immediately after the slide door is opened (immediately before full closure). It is also possible to slide and store it on the vehicle body side with the directional movement.
The case 2 and the cover 3 constitute a protector 4. A horizontally long space for storing the harness is formed in the protector 4. The lower opening 16 of the protector 4 extends straight from the front wall 10 of the case 2 to the opening 19 at the rear end. The opening 19 at the rear end may be closed by a vertical wall (not shown).
The sliding contact guide 5 is raised substantially in a mountain shape from the lower wall 9 (the lower end of the substrate portion 8) and the lower end of the cover 3, and is formed symmetrically with the substrate portion 8 and the vertical substrate portion of the cover 3. . The sliding contact guide 5 on the cover 3 is shorter than the substrate 8 by the dimension of the opening 16. The mountain shape of the sliding contact guide 5 may be curved or linearly inclined, and has inclined portions 5a and 5b of approximately the same length as the first half and the second half of the protector 4.
As shown in a sectional view of one embodiment of the sliding contact guide 5 in FIG. 4, the sliding contact guide 5 is formed in a rail shape on the inner surface of the substrate portion 8 of the case 2 and the inner surface of the cover 3. The rail 5 has a curved surface 5d on the upper side for receiving the spherical sliding member 7, and is formed in a substantially triangular cross section. The protruding length of the rail 5 is set to a length that allows the wire harness 6 to be loosely inserted between the pair of rails 5. A space for harness insertion exists between the pair of rails 5.
The spherical sliding member 7 is formed of a synthetic resin material, for example, is divided into two right and left parts, and the wire harness 6 is sandwiched in the inner hollow hole 20. (Not shown). When a synthetic resin corrugated tube 21 (FIG. 1) is attached to the outer periphery of the wire harness 6, the inner ridge of the sliding member 7 is engaged with the circumferential groove of the corrugated tube 21. The sliding member 7 is rotatable in the circumferential direction and is prevented from moving (fixed) in the longitudinal direction of the harness. In FIG. 1, the outer diameter of the sliding member 7 is set to be larger than the width of the lower mouth portion 16 so that the sliding member 7 does not protrude outward from the mouth portion 16.
It is also possible to form two pairs of upper and lower rails 5 and hold the wire harness 6 between the upper and lower rails 5 without falling off. Further, the cross-sectional shape of the rail 5 can be appropriately set according to the shape of the sliding member 7. Further, in a state where the sliding member 7 is not divided and the wire harness 6 is inserted through the center hole 20 (FIG. 4), the wire harness 6 is wound around a projecting piece (not shown) in the harness longitudinal direction by tape winding or the like. It is also possible to fix with. Further, the spherical sliding member 7 can be formed integrally with a protective tube such as a corrugated tube on the outer periphery of the wire harness.
According to the rail 5 and the sliding member 7 of FIG. 4, the sliding member 7 is brought into contact (sliding contact) on the rail 5 by utilizing the weight of the wire harness 6, thereby simplifying the structure and reducing the cost. You. FIG. 1 shows the sliding member 7 and the sliding contact guide 5 of the embodiment of FIG.
FIG. 5 shows another embodiment of the sliding contact guide. The sliding contact guide 5 ′ is a mountain-shaped guide hole (cam hole) formed through the substrate portion 8 and the cover 3 of the case 2. . The shaft 22 of the sliding member 7 'is slidably engaged with the guide hole 5'. The front and rear ends (lower ends) of the guide holes 5 ′ do not open to the lower end of the cover 3 so that the shaft portion 22 does not come off from the cover 3.
The sliding member 7 ′ is formed of a synthetic resin material, and is fixed to the wire harness 6 by pinching or engaging with a concave groove of the corrugated tube 21 (FIG. 1). And a pair of shaft portions 22 radially protruding from the portion 23. The annular portion 23 is divided into, for example, left and right and fixed to each other by locking means. Alternatively, it is fixed to the wire harness 6 by a tape or the like with a protruding piece (not shown). Alternatively, it is formed integrally with the protective tube on the outer periphery of the wire harness.
According to the embodiment of FIG. 5, since the sliding position of the sliding member 7 'is accurately defined by the guide hole 5', the contraction of the wire harness 6 in the protector 4 is performed with an accurate diameter, and the sliding member The backlash in the vertical direction of 7 'is also prevented.
When the slide door of FIG. 1 is fully closed, the sliding member 7 is located at the rear end of the sliding contact guide 5 (the lower end side of the rear inclined portion 5a). The wire harness 6 draws a small loop downward in the latter half of the protector 4 while inclining upward from the sliding member 7 along the inclined portion 5 a of the sliding contact guide 5, crosses the wire harness rear portion 21, and forms an upper mouth portion 13. And rises along the rear wall 12 in a curved shape as indicated by reference numeral 6a. The wire harness rear portion 21 is pulled rearward from the lower opening 16 toward the harness fixing portion 17 on the vehicle body side.
When the sliding door of FIG. 2 is half-opened (in a state where the sliding door is opened rearward to about half of the entire stroke), the harness fixing portion 17 on the vehicle body side is immovable, and the protector 4 is integrated with the sliding door for about half a stroke. With the retreat, the sliding member 7 rises along the rear half inclined portion 5 a of the sliding contact guide 5, and is located substantially at the top 5 c of the sliding contact guide 5.
As a result, the wire harness 6 draws a large loop in the front half of the protector 4, and the wire harness 6 does not loosen from the lower opening 16 to the harness fixing portion 17. The wire harness 6 is housed in a loop shape. Thereby, the excess length (slack) of the wire harness 6 between the slide door and the vehicle body when the slide door is half-opened is reliably absorbed.
When the slide door of FIG. 3 is fully opened, the protector 4 retreats integrally with the slide door, and the sliding member 7 descends along the front half inclined portion 5b of the sliding contact guide 5, and is located at the front end of the inclined portion 5b. Accordingly, the wire harness 6 is drawn forward toward the harness fixing portion 17 of the vehicle body while being reduced in diameter in the front half of the protector 4. With the opening and closing of the slide door, the wire harness 6 swings back and forth along the lower opening 16.
As described above, the sliding member 7 (7 ') slides along the substantially mountain-shaped sliding contact guide 5 (5') with the opening and closing of the sliding door, so that the wire harness 6 loops within the protector 4. The wire harness 6 is smoothly and reliably contracted by being pulled out toward the vehicle body while being reduced in diameter while being loop-shaped.
In FIG. 1, the wire harness portion 21 from the sliding member 7 to the harness fixing portion 17 is exposed outside the protector 4, so that a flexible protective tube (exterior member) such as a corrugated tube (substituted by reference numeral 21) is covered. It is preferable to wear it to achieve waterproofing and dustproofing.
Further, it is preferable to increase the rigidity of the wire harness portion from the sliding member 7 to the upper mouth portion 13 in order to bend in a loop shape. (If the wire harness portion is flexible, a loop cannot be drawn smoothly and the loop shape is broken. ). In particular, it is preferable that the rigidity of the wire harness 6 is not reduced when the outside air temperature and humidity are high.
For this reason, as shown in FIG. 6, for example, as shown in FIG. 6, the insulating coating 26 covering the core wire 25 of each electric wire 24 forming the wire harness 6 is formed of a material which is hardly affected by temperature, such as polyethylene or fluorine resin, or As described above, it is preferable that the protective tube 28 surrounding the plurality of electric wires 24 ′ (wire bundle) is formed of a material whose rigidity does not decrease with temperature or humidity as in FIG. 6. It is also effective to simultaneously employ the configurations shown in FIGS. 6 and 7 (using the insulating coating 26 and the protective tube 28 simultaneously).
6 and 7 (stiffness stable resin material) is not limited to the wire harness portion 6b extending from the sliding member 7 (FIG. 1) to the inside of the protector 4, but the wire harness portion extending from the sliding member 7 to the outside of the protector 4. (Substituted by reference numeral 21) can also be applied integrally.
As shown in FIGS. 8 (a) and 8 (b), a curved (arc-shaped) rigid member 29 made of synthetic resin or metal is provided on the bent outer surface of the loop-shaped bent portion (loop portion) 6b of the wire harness 6. It is also effective to make the wire harness 6 easy to loop. The rigid member 29 is configured by connecting a pair of curved plates 30 so as to be rotatable (openable and closable) at a central hinge (fulcrum) 31. The curved plate 30 may also be curved in the width direction (wire harness radial direction). The curved plate 30 is fixed to the wire harness 6 with a tape 32 or the like.
When the rigid member 29 is a synthetic resin material, the hinge 31 may be a thin hinge. The rigid member 29 also functions as an auxiliary protector that protects the wire harness 6 from friction with the inner surface of the protector 4. The shape of the rigid member 29 is not limited to the plate shape, but may be a curved rod shape.
When the slide door is fully closed or fully opened, as shown in FIG. 8 (a), the wire harness 6 is reduced in diameter and the rigid member 29 is rotated in the closing direction to secure the loop shape of the wire harness 6, and the slide door is closed. When the wire harness 6 is partially opened, the rigid member 29 rotates in the opening direction while the diameter of the wire harness 6 is greatly increased as shown in FIG. As described above, the loop shape of the wire harness 6 is accurately maintained by the rigid member 29, and the extra length of the wire harness 6 accompanying opening and closing of the slide door is reliably absorbed.
9 to 11 show a second embodiment of the power supply device according to the present invention. The power supply device 33 is provided vertically (vertically) in a slide door (slide structure) of an automobile. FIG. 9 shows a state in which the slide door is fully closed, and FIG. 10 shows a state in which the slide door is half-open. 11 shows a state where the slide door is fully opened. The same components as those in the embodiment of FIG. 1 are denoted by the same reference numerals, and detailed description is omitted.
As shown in FIG. 9, the power supply device 33 includes a case 34 made of a synthetic resin whose height is kept low, a cover 35 made of a synthetic resin attached to the case 34 (indicated by a chain line), the case 34 and the cover.

And a slidable sliding member 7.
The case 34 and the cover 35 constitute a protector 36. A horizontally long space for storing the harness is formed in the protector 36. The case 34 is formed in a horizontally long and substantially rectangular shape, and has a curved portion 40 along the loop-shaped bent portion 6b of the wire harness 6 above the front and rear wall portions 38 and 39. The front and rear wall portions 38 and 39 follow the upper and lower parallel wall portions 41 and 42, and the peripheral walls around the vertical substrate portion 43 are formed by the respective wall portions 38 to 42, and are formed by the lower end of the cover 35 and the lower wall 42. A horizontally long harness leading-out (swinging) opening 44 is formed therebetween, and a harness leading-out (fixing) narrow opening 45 is formed at a lower portion of the rear wall 39. One 21 of the wire harness 6 is routed from the horizontally long mouth portion 44 to the vehicle body side through the harness fixing portion 17, and the other 6 d of the wire harness 6 is fixed to the vicinity of the rear mouth portion 45 while facing the slide door side. Be routed.
The sliding guide 37 is linearly inclined, and the upper end 37a of the sliding guide 37 is located inside the upper part of the rear wall 39 of the protector 36, and the lower end 37b of the sliding guide 37 is located inside the lower part of the front wall 38. I have. The sliding member 7 is fixed to the wire harness 6, and the sliding member 7 moves up and down while moving forward and backward along the sliding contact guide 37.
The sliding contact guide 37 and the sliding member 7 can use the forms shown in FIGS. 4 and 5 as they are. That is, the spherical sliding member 7 of the wire harness 6 is slidably engaged with a pair of left and right inclined rails of the case 34 of the protector 36 and the cover 35 as shown in FIG. 4, or the case of the protector 36 as shown in FIG. The shaft portion 22 of the annular sliding member 7 'of the wire harness 6 is slidably engaged with the inclined guide hole 5' of the cover 34 and the cover 35. FIG. 9 shows the configuration of FIG.
When the slide door of FIG. 9 is fully closed, the sliding member 7 is located at the rear upper end 37a of the sliding contact guide 37, and the wire harness 6 is bent into a horizontally long loop with a large diameter in the horizontally long protector 36. 7, extending from the rear end side of the horizontally long mouth portion 44 to the vehicle body side while hanging down along the rear wall 39 of the protector 36.
When the slide door of FIG. 10 is half-opened, the protector 36 retreats integrally with the slide door, the position of the harness fixing portion 17 on the vehicle body side remains unchanged, and the slide member 7 moves about halfway along the sliding contact guide 37. Then, the wire harness 6 is located at a middle portion in the longitudinal direction of the sliding contact guide 37, the wire harness 6 is bent to a smaller diameter than when fully closed in FIG. 9, and the loop portion 6 b is located in the front half of the protector 36. The wire harness portion 6d following the loop portion 6b extends straight in the horizontal direction along the lower wall 42 of the protector 36, and reaches a mouth portion 45 at the rear end on the harness fixing side.
When the slide door of FIG. 11 is fully opened, the protector 36 moves to the rear of the vehicle integrally with the slide door, and accordingly, the sliding member 7 descends while moving forward along the slide contact guide 37 and descends. 10, the loop portion 6b of the wire harness 6 is reduced in diameter to a smaller diameter than the half-open state in FIG. A harness portion 6d following the loop portion 6b extends straight along the lower wall 42 of the protector 36. With the opening and closing of the sliding door, the wire harness portion 21 extending from the sliding member 7 to the outside of the protector swings back and forth along the elongated opening 44.
Thus, with the opening and closing operation of the slide door, the wire harness 6 expands and contracts in the horizontal direction while bending in a loop shape in the horizontally long protector 36 to absorb the extra length. For this reason, the protector 36 is made compact in the height direction, unlike the conventional leaf spring in which the excess length of the wire harness is absorbed upward.
The structure for increasing the rigidity of the electric wire 24 shown in FIG. 6, the structure for increasing the rigidity of the wire harness 6 shown in FIG. 7, and the structure of the rigid member shown in FIGS. 7 (a) and 7 (b) are shown in FIGS.

By maintaining it, smooth and reliable extra length absorption can be achieved.
The power supply device according to each of the above-described embodiments can be applied to various types of slide doors other than the slide door of an automobile, and a slide structure such as a slide sheet of an automobile described below. In this case, the harness wiring structure from the vehicle body to the slide door is a harness wiring structure from the fixed structure to the slide structure.
Further, if resin molding is possible, the cases 2 and 34 and the covers 3 and 35 may be formed as integral protectors 4 and 36. Further, the sliding guides 5 and 37 can be formed separately from the protectors 4 and 36 instead of being integrated with each other and fixed to the protectors 4 and 36. Also, the sliding members 5, 5 ', 37 may be formed not in a pair but in the case 2, 34 or the cover 3, 35, and the sliding members 7, 7' may be guided by one sliding guide. It is possible. In this case, assuming that the sliding contact guides 5, 5 ', 37 are provided on the cases 2, 34, it is preferable that the sliding members 7, 7' contact the inner surfaces of the covers 3, 35 without play. Further, a guide groove can be used instead of the guide hole 5 'as the sliding contact guide. Further, the sliding contact guide 37 in FIG. 9 may have a curved inclination instead of a linear inclination. In this case, unlike the sliding contact guide 5 of FIG. 1, one end 37a of the sliding contact guide 37 is located higher than the other end 37b, and the intermediate portion is always located lower than the one end 37a. Gradually decrease from one end to the other end. Further, the sliding member 5 is not limited to a spherical shape, and may have a concave groove portion for sliding engagement with the pair of rails 5 even if it is spherical.
Further, since the wire harness 6 constitutes one product, that is, the power supply devices 1 and 33 while being housed in the protectors 4 and 36, the wire harness 6 can be regarded as a component of the power supply devices 1 and 33. Further, the protectors 4 and 36 can be provided not on the sliding door but on the vehicle body side. In this case, the protectors 4 and 36 may be placed horizontally and horizontally on the vehicle body side, and the lower walls 9 and 42 of the cases 2 and 34 may be opened to form the horizontally long mouth portions 16 and 44 for harness leading and swinging. is there.
