  However, in the power feeding device 48 using the conventional flexible harness protector 43 for an automobile door, the harness protector 43 is connected to the vehicle body 6 when the door 11 shown in FIG. Therefore, there is a concern that an excessive bending force (stress) is applied to the harness protector 43 and the internal wire harness.

  This is not limited to the automobile door 11 and may occur when the same power supply device is applied to various opening / closing bodies such as a trunk, a back door, or a door other than the automobile. Further, there is a concern that the harness protector may be bent at a small angle not on the vehicle body side but on the case side, depending on the opening / closing angle of the opening / closing body, the assembly angle of the harness protector to the opening / closing body, and the like.

  SUMMARY OF THE INVENTION In view of the above, the present invention has an object to provide a harness protector for an opening / closing body and a power feeding device using the same, which can cause a bending operation to be performed with a large radius without stress concentration when the opening / closing body is rotated. And

In order to achieve the above object, a harness protector for an opening / closing body according to claim 1 of the present invention is formed in a substantially rectangular cylindrical cross section, and two wide walls facing each other have flexibility in the thickness direction. Then, one end side of the wall portion is slidably engaged with the opening / closing body side, the other end side of the wall portion is connected to the body side, a wire harness is inserted inside the wall portion, and when the opening / closing body is opened, In a harness protector for an opening / closing body, in which one end side portion of the wall portion extends straight and the other end portion easily bends to a small diameter, the wall thickness of the wall portion gradually decreases from the other end side to the one end side. It is formed .
The opening / closing body harness protector according to claim 2 is characterized in that, in the opening / closing body harness protector according to claim 1, the thickness of the wall portion is changed stepwise.

  With the above configuration, when opening and closing the open / close body, for example, the other end of the harness protector is easy to bend, and even when trying to bend with a small radius on the body side, the thick plate part of the wall part increases the rigidity and makes it difficult to bend. The harness protector bends with a uniform large radius over the entire length because the thin plate portion on one end side (opening / closing body side) of the protector lowers the rigidity of the wall portion to facilitate bending. This prevents bending stress concentration of the harness protector and the inner wire harness.

The harness protector for an opening / closing body according to claim 3 is formed in a substantially rectangular tube shape in cross section, and two opposed wide wall portions have flexibility in the thickness direction, and one end side of the wall portion is on the opening / closing body side. It engages slidably, the other end of the wall is connected to the body, a wire harness is inserted inside the wall, and one end of the wall extends straight when the opening / closing body is opened. In the harness protector for an opening and closing body in which the other end portion is easily bent to a small diameter, the plurality of grooves in the wall width direction gradually reduce the pitch from the other end side to the one end side of the wall portion. It is characterized by being arranged in parallel .

  With the above configuration, the other end of the harness protector, for example, is easily bent when the opening and closing body is opened and closed, and even when trying to bend with a small radius on the body side, the portion with few or no grooves increases the rigidity of the wall. The harness protector bends with a uniform large radius over the entire length by making it difficult to bend and by making the portion of the harness protector having many grooves on one end side (opening / closing body side) easy to bend by reducing the rigidity of the wall portion. This prevents bending stress concentration of the harness protector and the inner wire harness.

The harness protector for an opening / closing body according to claim 4 is formed in a substantially rectangular tube shape in cross section, and two wide wall portions facing each other have flexibility in the thickness direction, and one end side of the wall portion is on the opening / closing body side. It engages slidably, the other end of the wall is connected to the body, a wire harness is inserted inside the wall, and one end of the wall extends straight when the opening / closing body is opened. in liable closing-body harness protector portion of the other end bent to a small diameter, toward one end from the other end of the wall portion, the wall portion, by increasing the gradual pitch plurality of ribs of the wall portion width direction It is characterized by being arranged in parallel .

  With the above configuration, when opening and closing the opening / closing body, for example, the other end of the harness protector is easily bent, and even when trying to bend with a small radius on the body side, the portion with many ribs increases the rigidity of the wall and makes it difficult to bend, The harness protector bends with a uniform large radius over the entire length by reducing the rigidity of the wall portion and making the wall protector bend easily by bending a portion of the harness protector on one end side (opening / closing body side). This prevents bending stress concentration of the harness protector and the inner wire harness.

Closing-body harness protector according to claim 5 is the closing-body harness protector according to any one of claims 1-4, the two wall portions or wall portions of the bent inwardly claim 1 or A portion in which the plate thickness according to 2 is changed or a groove according to claim 3 or a rib according to claim 4 is provided.

  With the above configuration, when the thicknesses of both opposing wall portions are changed, or when grooves or ribs are provided on both wall portions, the action of the harness protector being bent uniformly with a large radius is promoted. In addition, even when the thickness of only the inner wall portion of the bend is changed, or even when the groove or rib is provided only on the inner wall portion of the bend, the change of the plate thickness, groove or rib only on the outer wall portion of the bend. The harness protector bends evenly with a large radius more accurately than when applied. In addition, the cost is reduced by applying the plate thickness change and the grooves and ribs to only one of the walls.

A power supply device comprising the opening / closing body harness protector according to claim 6 is the power supply device including the opening / closing body harness protector according to any one of claims 1 to 5 , wherein one end side of the wall portion is provided. This portion is slidably engaged with the case, and the slack of the wire harness is absorbed in the case.

  With the above configuration, the harness protector is pulled out together with the wire harness from the case when the opening / closing body is opened, and the harness protector is pulled into the case integrally with the wire harness when the opening / closing body is closed. The wire harness is bent into a loop shape, an S shape, a wave shape, or the like in the case to absorb slack (excess length). Since the harness protector bends uniformly with a large radius when the opening and closing body is opened and closed, an excessive bending force is not applied to the harness protector and the wire harness, and the drawing and retracting operation with respect to the case is smoothly performed without being caught.

According to the first or second aspect of the invention, since the thick plate portion of the harness protector is reinforced and bent with a large radius when the opening / closing body is opened and closed, the harness protector and the inner wire harness are bent and stress concentrated. Is prevented, the bending durability of the harness protector and the wire harness is increased, and the reliability of the constant power supply from the body to the opening / closing body is improved.

According to the third aspect of the invention, when the opening / closing body is opened / closed, the portion with a small groove of the harness protector reinforces the portion that is easily bent and bends with a large radius. It is prevented, the bending durability of the harness protector and the wire harness is increased, and the reliability of the constant power supply from the body to the opening / closing body is improved.

According to the fourth aspect of the invention, when the opening and closing body is opened and closed, the portion where the ribs of the harness protector are easily bent is reinforced and bent at a large radius, so that the harness protector and the inner wire harness are not bent or concentrated in stress. It is prevented, the bending durability of the harness protector and the wire harness is increased, and the reliability of the constant power supply from the body to the opening / closing body is improved.

According to the invention described in claim 5 , when the wall thickness change and grooves or ribs are applied to both opposing wall portions, the uniform bending of the harness protector is promoted, and the effect described in claim 1 is promoted. . In addition, even when plate thickness changes or grooves or ribs are applied only to the inner wall of the bend, the harness protector can be uniformly bent and the cost for applying plate thickness changes and grooves and ribs can be reduced. Is done.

According to the invention described in claim 6, since the harness protector bends uniformly with a large radius when the opening and closing body is opened and closed, an excessive bending force is not applied to the harness protector and the wire harness, and the pulling and retracting operation with respect to the case is not caught. The opening / closing operation of the opening / closing body is smoothly and reliably performed with a small force.

  FIG. 1 is an exploded perspective view showing an embodiment in which a power supply device equipped with a harness protector for an opening / closing body according to the present invention is applied to an automobile door, and FIGS. 2 to 3 show a first embodiment of the harness protector for an opening / closing body. It is sectional drawing shown.

  As shown in FIG. 1, the power supply device 1 includes a flexible harness protector 2 and a case 3 that guides and accommodates the harness protector 2 in a slidable manner. Since the configuration other than the harness protector 2 is the same as that of the conventional example, the same reference numerals are given and detailed description is omitted.

  The harness protector 2 is preferably formed of a flexible synthetic resin material such as PET (polyethylene terephthalate). In the harness protector 2, a portion pulled out from the case 3 is bent in a curved shape (arc shape), and a portion drawn into the case 3 slides straight along the inner surface of the case.

  As shown in FIG. 2 (a cross-sectional view of the harness protector 2 as viewed from above), the harness protector 2 is composed of two flexible resin plates on the left and right, and the two resin plates are provided on both wall portions (side walls) 21 thereof. The upper and lower end portions are joined (adhered or welded) with a gap (harness insertion space) 22 in between, and the like is formed into a cylindrical shape (cylindrical shape elongated in the vertical direction) having a substantially rectangular cross section. Instead of joining the upper and lower end portions, it is possible to form the upper and lower narrow wall portions (not shown). However, in this case, the flexibility cannot be denied.

  The left and right wall portions 21 of the harness protector 2 are formed by changing the plate thickness stepwise. That is, in FIG. 1, the portion (a portion that is most easily bent) 2a connected to the vehicle body 6 is formed to be the thickest, and the portion 2b that enters and engages the case 3 is formed to be the thinnest. Are gradually formed thin from the vehicle body 6 side to the case 3 side (door 11 side). In this example, the intermediate portion is formed in two stages, and the thickness of the harness protector is changed in four stages (wall parts 21a to 21d having four stages of different thicknesses are formed).

  As a result, the harness protector 2 has high rigidity near the vehicle body 6 and low rigidity near the case 3 (from the door 11). The high rigidity portion is difficult to bend and the low rigidity portion is easily bent. This part is not bent with a small radius as in the prior art, but is bent with a large radius like the part near the case.

  How to change the plate thickness, how much to change the plate thickness, how much to change the length ratio of the wall portions 21a to 21d having different plate thicknesses, etc. It is appropriately set according to the length, the mounting form, the opening / closing angle of the door (opening / closing body) 11 and the like. Reference numerals 21a to 21d are collectively referred to as portions where the plate thickness is changed.

  In this example, the plate thickness is changed in four stages, and the amount of reduction in the plate thickness (how much the thickness is reduced) is substantially the same for each plate thickness. Further, the lengths of the wall portions 21a to 21d having different plate thicknesses are not the same, and in this example, the thickest wall portion 21a and the thinnest wall portion 21d are formed to be relatively short with substantially the same length. The two wall portions 21b and 21c are formed to have the same length and are relatively long.

  The lengths and thicknesses of the four wall thicknesses 21a to 21d are the same in the pair of left and right resin plates (21), and the wall thicknesses 21a to 21d of the respective thicknesses are located opposite to each other. A narrow space is located between the left and right wall portions 21a with a large thickness, and a wide space is located between the left and right wall portions 21d with the smallest thickness. Even if it is said to be a narrow space, it has a sufficient area to allow the wire harness 23 to be inserted therethrough.

  Each wall part 21a-21d from which plate | board thickness differs is followed by each level | step-difference part 24 by the inner surface side. The shape of each stepped portion 24 may intersect at right angles or may intersect obliquely (tapered). It is also possible to gradually change the plate thickness by inclining the inner surfaces of both wall portions 21 from the distal end to the proximal end instead of forming the wall portions 21a to 21d in a staircase shape.

  As described above, the connecting part side of the harness protector 2 to the vehicle body 6 is thickest, the entry side to the case 3 is thinnest, and the intermediate part is gradually thinned from the vehicle body side to the case side. When the door is fully opened, the harness protector 2 bends in an arc shape with a uniform radius as shown in FIG. 3, so that bending at a small radius on the connecting portion side with the vehicle body 6 is prevented, and the harness protector 2 and the internal wire harness 23 Bending stress concentration is prevented, and the bending durability (life) of the harness protector 2 and the wire harness 23 is improved.

  The wire harness 23 is preferably a flat wire harness in which a plurality of electric wires are connected in parallel, or a flat wire harness in which a plurality of conductive circuits are arranged in parallel between insulating resin sheets. Even when the wire harness 23 is formed not in a flat shape but in a circular cross section, the harness protector 2 having the cross sectional shape in FIG. 2 can be applied (the harness protector is not thin but formed in, for example, a rectangular cross section). The same applies to other embodiments described later. It goes without saying that the wire harness 23 is integrally continued to the wire harness 18 on the case 3 side in FIG.

  In FIG. 1, the distal end portion of the harness protector 2 is fixed to the vehicle body 6 via a connecting member 10 or a locking clip, and the proximal end portion of the harness protector 2 is slidably inserted into the guide portion 3 a of the case 3. Match. The harness protector 2 and the case 3 constitute the power feeding device 1. The flat wire harness in the harness protector 2 is bundled in a circular cross section in the circular extra length absorbing portion 3b of the case 3 and wound in a loop shape, and is led out of the case 3 to be supplied to the door side electrical equipment 27 and auxiliary equipment. 28 etc.

  In the embodiment of FIG. 2, the step thickness 24 is provided on the inner surface of the both wall portions 21 of the harness protector 2 to change the plate thickness. However, the step thickness is provided on the outer surface of the both wall portions 21 to change the plate thickness. It is also possible. However, in this case, it is preferable to form the stepped portion 24 in a tapered shape in consideration of the slidability to the case 3.

  Alternatively, the step portions 24 may be provided only on one of the left and right wall portions 21 to form the wall portions 21a to 21d having different plate thicknesses. If anything, it is preferable to change the thickness of the wall portion 21 on the inside of the bend in order to make the bend smoothly.

  In order to change the plate thickness of the wall portion 21 of the harness protector 2, for example, it is preferable to form a molding die (not shown) in a stepped shape in advance during resin molding with the harness protector 2 deployed. Alternatively, the wall portion 21 of the harness protector 2 can be permanently deformed by pressing it in a step shape with a press (not shown).

  FIGS. 4-5 shows 2nd embodiment of the harness protector for opening / closing bodies which concerns on this invention. The material and overall shape of the harness protector 31 and the mounting form of the automobile door 11 in FIG.

  The harness protector 31 does not change the plate thickness but changes the bending rigidity over the entire length by providing grooves 32 in the direction perpendicular to the length (vertical direction or width direction) in the wall portion 33 at appropriate intervals. is there.

  The grooves 32 are rectangular in cross section and have the same size, length, and shape, and the pitch of the grooves 32 is gradually smaller on the side of the harness protector 31 shown in FIG. Are closely provided, and the pitch of the grooves 32 is gradually increased on the side of the harness protector 31 that is disposed closer to the vehicle body 6, and the grooves 32 are provided roughly or not provided at all. That is, the pitch of the grooves 32 of the harness protector 31 is set gradually larger from the case 3 side to the vehicle body 6 side.

  The portion of the harness protector 31 having a large number of grooves 32 is weak, this portion (portion near the case 3 in FIG. 1) 31b is easily bent, and the portion having few or no grooves 32 has high rigidity. The portion 31a near the vehicle body 6) is difficult to bend. Accordingly, when the automobile door 11 is fully opened, the portion near the case 3 of the harness protector 31 is flexibly bent, and the portion near the vehicle body 6 is bent with a radius larger than the conventional one, so that the harness protector 31 as a whole (over the entire length). B) Bend with a uniform large radius. Thereby, it is prevented that the harness protector 31 bends with a small radius near the vehicle body, and the bending durability of the harness protector 31 and the wire harness 23 is improved.

  The number, pitch, and the like of the grooves 32 are appropriately set according to the length and attachment form of the harness protector 31, the opening / closing angle of the door (opening / closing body) 11, and the like. The shape of the groove 32 is not limited to a rectangular cross section, but may be a triangular cross section or a trapezoidal shape.

  In this example, the groove 32 is provided only on the inner wall portion (wall portion on the side where the bending radius is small) 33 of the left and right flexible resin plates (wall portions) 33 and 33 ′ of the harness protector 31. The groove 32 is not provided in the wall portion 33 'on the outer side of the bend (the wall portion on the side with the larger bend radius) 33'. By providing the groove 32 on the bent inner wall 33, the groove 32 expands (the opening width of the groove 32 increases) when the wall 33 is bent as shown in FIG. By being easily bent, the outer wall portion 33 ′ can be easily bent following that, and the bending rigidity can be reliably reduced.

  Conversely, when a groove is provided only in the outer wall portion 33 ′ (not shown), the opening width of the groove is reduced during bending, and the rigidity of the inner wall portion 33 interferes with the bending, Flexibility tends to decrease. It is also possible to provide the same number of grooves 32 on both walls 33 and 33 'so as to face each other.

  In order to form the groove 32 in the wall portion 33 of the harness protector 31, for example, a groove forming rib (not shown) is previously formed in a molding die (not shown) when resin molding is performed in a state where the harness protector 31 is unfolded. It is preferable to make it protrude. Alternatively, the wall 33 of the harness protector 31 can be pressed with a rib of a press (not shown) to be recessed into a groove shape (permanently deformed).

  FIGS. 6-7 shows 3rd embodiment of the harness protector for opening / closing bodies which concerns on this invention. The material and overall shape of the harness protector 35 and the mounting form of the automobile door 11 shown in FIG.

  This harness protector 35 is not provided with a groove, but is provided with ribs 36 in the direction perpendicular to the length (vertical direction or width direction) on the inner surface of the wall portion 37 at appropriate intervals, thereby changing the bending rigidity over the entire length. It is.

  The ribs 36 are rectangular in cross-section and have the same size, length and shape. In FIG. 1, the pitch of the ribs 36 is gradually increased on the side of the harness protector 35 disposed near the case 3, and the ribs 36 are provided roughly. The pitch of the ribs 36 is gradually smaller on the side of the harness protector 35 that is disposed closer to the vehicle body 6 and the ribs 36 are densely provided. The pitch of the ribs 36 of the harness protector 35 is set gradually smaller from the case 3 side to the vehicle body 6 side. The arrangement is completely opposite to the groove 32 of the previous example.

  The portion 35a having a large number of ribs 36 of the harness protector 35 has high rigidity, and this portion (the portion close to the vehicle body in FIG. 1) is difficult to bend, and the portion 35b having few or no ribs 36 has low rigidity. The portion near the case 1) is easy to bend. Therefore, when the automobile door 11 is fully opened, the portion 35a of the harness protector 35 closer to the vehicle body is bent with a larger radius than before, and the harness protector is bent with a large radius (over the entire length). This prevents the harness protector 35 from being bent at a small radius near the vehicle body, and the bending durability of the harness protector 35 and the inner wire harness 23 is improved.

  The number, pitch, and the like of the ribs 36 are appropriately set according to the length and attachment form of the harness protector 35, the opening / closing angle of the door (opening / closing body) 11, and the like. The shape of the rib 36 is not limited to a rectangular cross section, and may be a triangular cross section or a trapezoidal shape.

  A wide concave groove 38 is formed between the ribs 36. The width of the groove 38 is smaller as the pitch of the rib 36 is smaller and larger as the pitch of the rib 36 is larger. The pitch of the rib 36 and the width of the groove 38 are proportional. The large width of the groove 38 has the same effect as the large number of the grooves 32 in the previous example (FIG. 4), and therefore the rigidity of the wide groove width portion (the portion where the ribs 36 are small) 35b is weak and easy to bend. A narrow portion (a portion having a large number of ribs) 35a corresponds to a portion having a small number of grooves 32 in the previous example, has high rigidity, and is difficult to bend.

  In this example, the rib 36 is provided only on the inner wall portion (the wall portion on the side having the smaller bending radius) 37 of the left and right flexible resin plates (wall portions) 37, 37 ′ of the harness protector 35. In addition, the rib 36 is not provided on the outer bent wall portion (the wall portion on the side with the larger bending radius) 37 ′. By providing the rib 36 on the inner wall 37, the groove 38 between the ribs 36 expands (the opening width of the groove 38 increases) when the wall 37 is bent as shown in FIG. Since the wall portion 37 is easily bent, the outer wall portion 37 ′ can be easily bent following it.

  On the contrary, when the rib 36 is provided only on the outer wall portion 37 ′, the opening width of the groove 38 between the ribs 36 is narrowed at the time of bending and the inner wall portion 37 (rigidity) obstructs the bending. And the flexibility is inferior. It is also possible to provide ribs 36 opposite to both wall portions 37 and 37 ′.

  In order to form the rib 36 on the wall portion 37 of the harness protector 35, for example, a rib forming groove (not shown) is previously formed in a molding die (not shown) at the time of resin molding in the deployed state of the harness protector 35. It is preferable to form it.

  In addition, although the rib 36 of this embodiment was formed in the longitudinal orthogonal direction of the harness protector 35, the rigidity of the harness protector is increased by forming the rib in the longitudinal direction instead of the longitudinal orthogonal direction and gradually increasing the number of ribs. It is also possible to increase it gradually.

  Further, in the above embodiments, the rigidity of the portions 2a, 31a, 35a near the vehicle body 6 of the harness protectors 2, 31, 35 is increased and the rigidity of the portions 2b, 31b, 35b near the case is decreased. If the portions 2b, 31b, 35b near the case rather than the vehicle body are easily bent with a small radius due to the mounting angles of the 2, 31, 35, etc., the harness protectors 2, 31, 35 The rigidity of the portions 2a, 31a, and 35a can be reduced, and the rigidity of the portions 2b, 31b, and 35b near the case can be increased to cope with this.

  If the harness protectors 2, 31, 35 are easily bent at a small radius between the harness protectors 2, 31, 35, that is, between the vehicle body 6 and the case 3, the harness protectors 2, 31, 35 are used. The rigidity of the intermediate part in the longitudinal direction can be increased, and the rigidity of the parts 2a, 31a, 35a closer to the vehicle body and the parts 2b, 31b, 35b closer to the case can be reduced to cope with this. Needless to say, the change in rigidity is made by changing the thickness of the plate and the grooves 32 and ribs 36 in each example.

  In addition, in the power supply device 1 of FIG. 1, instead of providing the case 3 on the door panel 12, a portion corresponding to the case 3 (portion corresponding to the guide portion 3 a and the extra length absorbing portion 3 b) is replaced with, for example, a synthetic resin door trim 13. It is also possible to form it integrally. Further, the structure of the surplus length absorbing portion 3b is not necessarily limited to that in which the wire harness 18 is bent (expanded / contracted) in a loop shape. For example, the wire harness 18 or the flat wire harness 23 may be bent in a substantially S shape or a wave shape. Alternatively, the wire harness 18 can be routed in an inverted V shape along the door panel 12 and can be swung around the top portion as a fulcrum.
