JP 2001-354085 A

  The protective case employed in the power supply cable device of Patent Document 1 is composed of two members, a case main body and a cover attached in a manner of being superimposed on the case main body. In many cases, such a case has a gap called play between the case body and the cover. The clearance makes it easy to attach the case body to the cover, while the case body and the cover collide when vibrations that occur when the vehicle is running or when the sliding door is opened or closed are propagated to the protective case. There is a risk. Since the collision between the case main body and the cover causes noise, there is room for improvement.

  This invention is made | formed in view of such the actual condition, The objective is to provide the electric power feeding unit apparatus for vehicles which has the noise suppression effect.

  In order to solve the above-described problems, a vehicle power supply unit is provided on a vehicle body side by being deformed as the slide opening / closing body is displaced while being accommodated in a case attached to the slide opening / closing body of the vehicle. And a harness for electrically connecting a power supply target provided to the slide opening / closing body, wherein the case includes a base and a cover overlaid on the base, The base and the cover have attachment portions that are attached to each other by being restricted from being separated from each other in the overlapping direction, and when the base and the cover are attached by the attachment portions, The gist of the invention is that a crushing rib whose front end portion is crushed and deformed is provided on at least one of the base and the cover. .

  According to this configuration, when the base and the cover are attached, the gap between the base and the cover is filled with the crushed ribs that are crushed and deformed. Thereby, when vibration is input to the case, the base and the cover are displaced together. That is, since the collision between the base and the cover is suppressed, the generation of abnormal noise due to the collision is suppressed.

  In the above configuration, the crushing rib has a protruding length longer than a first distance of a gap in the overlapping direction provided between the base and the cover in a state where the base and the cover are attached. It is preferable to provide a first rib.

  According to this configuration, the mutual displacement of the base and the cover in the overlapping direction is suppressed by the cooperation of the crushing deformed first rib and the mounting portion. Thereby, even if the vibration in the overlapping direction is input to the vehicle power supply unit device, the generation of abnormal noise is suppressed.

  The said structure WHEREIN: The said crushing rib is provided with the 2nd rib which has a protrusion length longer than the 2nd distance of the clearance gap in the direction which cross | intersects the said superimposition direction provided between the said base and the said cover. preferable.

  According to this configuration, the displacement of the base and the cover in the direction intersecting the overlapping direction is suppressed by the second deformed rib. Thereby, even if the vibration in the direction crossing the overlapping direction is input to the vehicle power supply unit device, generation of abnormal noise is suppressed.

  The said structure WHEREIN: It is preferable that the said attaching part is a snap fit provided in the outer edge of the said base and the said cover by setting space | interval, and the said crushing rib is provided between the said snap fits.

  Since the base and the cover are in a holding relationship with each other at the portion where the snap fit is provided, the base and the cover are less likely to collide even if vibration is input at the portion where the snap fit is provided. On the other hand, since the base and the cover are separated from each other in a portion where the snap fit is not provided, the base and the cover are likely to collide when vibration is input in the portion where the snap fit is not provided.

  According to this configuration, the crushing rib is provided in a portion where the snap fit is not provided. Since the base and the cover are always in contact with each other at the portion where the crushing rib is provided, the base and the cover are unlikely to collide with each other at that portion. Therefore, even if vibration is input, the generation of abnormal noise is suppressed.

  In the above-described configuration, one of the base and the cover is inserted with respect to the other, and has the crushing rib, and the crushing rib has a linearly continuous tip portion that undergoes crushing deformation. It is preferable to extend in this way.

  According to this configuration, the crushing rib has a shape in which the crushing and deforming front end portion is linearly continuous, so that dimensional management at the time of manufacture is easy.

  The vehicle power supply unit device of the present invention has an effect of suppressing abnormal noise.

Hereinafter, an embodiment of a power supply unit provided on a slide door on the right side of the vehicle will be described with reference to the drawings.
As shown in FIG. 1, the power supply unit 1 includes a case 2 and a wire harness 3 provided inside the case 2.

  As shown in FIGS. 2, 3 (a), 3 (b), 3 (c), and 3 (d), the wire harness 3 has a stroke corresponding to the opening and closing of the slide door 4. One end is exposed from the lower part of the case 2 and is connected to the vehicle body side connecting part 5, and the other end is connected to the sliding door side connecting part 6 provided at the upper part of the case 2. The vehicle body side connection portion 5 is a battery (not shown) provided on the vehicle body, the slide door side connection portion 6 is a motor that functions as a drive source for opening and closing the slide door 4, and a power window opening and closing closer device. Is connected to each power supply target such as a motor that functions as a drive source when operating.

  An intermediate portion of the wire harness 3 is fixed by a clamp 7 provided in the case 2. The pre-length portion of the wire harness 3 is provided in a portion between the vehicle body side connection portion 5 and the clamp 7. A pre-length portion of the wire harness 3 provided between the vehicle body side connection portion 5 and the clamp 7 is defined as a pre-length portion 3a. In addition, the part of the sliding door side connection part 6 from the clamp 7 of the wire harness 3 is arrange | positioned so that the base 3rd edge part 14 of the protector base 10 mentioned later may be followed (FIG.3 (c) and FIG.3). (See (d)).

Since the vehicle body side connection part 5 is located behind the clamp 7 when the slide door 4 is fully closed, the wire harness 3 extends so that the pre-length portion 3a is smoothly curved upward.
As the sliding door 4 is displaced from fully closed to fully opened, that is, as the sliding door 4 is displaced rearward, the clamp 7 is displaced rearward. Thereby, the wire harness 3 slides in the case 2 while curving so that the curve of the pre-length portion 3a gradually becomes steep. Accordingly, the pre-length portion 3a of the wire harness 3 is curved so as to be steepest when the slide door 4 is fully opened.

  Thereby, the battery and the power supply target are always electrically connected regardless of the open / close position of the slide door 4. Thereby, each function provided in the slide door 4 such as the opening / closing operation of the slide door 4 and the opening / closing operation of the power window can be used regardless of the opening / closing position of the slide door 4.

  The case 2 includes a protector base 10 and a protector cover 20 attached by being superimposed on the protector base 10. The protector base 10 and the protector cover 20 are made of an elastically deformable material. In addition, the overlapping direction of the protector base 10 and the protector cover 20 in this example coincides with the vehicle width direction.

  As shown in FIG. 4, the protector base 10 has a base main body portion 11 having a triangular plate shape with rounded corners as a whole. In addition, the base main-body part which extends the edge part extended in the front-back direction of the base main-body part 11 so that it goes gradually upwards as it goes to the front from the rear end part of the base 1st edge part 12 and the base 1st edge part 12. 11 is defined as the base second edge 13. Further, the edge of the base body 11 that connects the front end of the base first edge 12 and the front end of the base second edge 13 is defined as a base third edge 14. The connecting portions of these edge portions are smoothly continuous.

  As shown in FIG. 5, the base second edge 13 and the base third edge 14 are peripheral walls that are bent from the base body 11 toward the protector cover 20, that is, outward in the vehicle width direction. The base second edge portion 13 and the base third edge portion 14 are provided with engagement convex portions 15 for snap fit at predetermined intervals. Further, the protector base 10 has a crushing rib 16 provided at an intermediate position between adjacent engaging projections 15.

  As shown in FIG. 6 (a), the crushing rib 16 includes a first rib 17 provided on the base body 11, and inner peripheral surfaces of both edges of the base second edge 13 and the base third edge 14. And a second rib 18 provided on the outer surface.

  The first rib 17 is a triangular prism extending in the vehicle width direction while the first rib 17 is directed toward the plate surface direction of the base main body 11 intersecting the vehicle width direction, more precisely toward the second rib 18. The first rib 17 and the second rib 18 are provided in such a manner that the top portion 17a of the first rib 17 and the top portion 18a of the second rib 18 are orthogonal to each other and continuous. Therefore, the crushing rib 16 is provided in an L shape as a whole.

  The protruding length of the crushing rib 16, that is, the dimension between the plate surface of the base main body 11 and the top 17 a of the first rib 17, and the inner peripheral surface of the base second edge 13 or the base third edge 14. And the top portion 18a of the second rib 18 are set to a protruding length S + that is slightly longer than a gap size S described later. It should be noted that the top portion 17a of the first rib 17 and the top portion 18a of the second rib 18 correspond to tip portions that are crushed and deformed.

  As shown in FIG. 7, the protector cover 20 has a cover main body portion 21 that has a triangular plate shape with rounded corners as a whole. In addition, the cover main-body part which extends the edge part extended in the front-back direction of the cover main-body part 21 so that it goes to the front gradually from the cover 1st edge part 22 and the rear-end part of the cover 1st edge part 22 toward the front. 21 is defined as a cover second edge 23. Further, the edge of the cover body 21 that connects the front end of the cover first edge 22 and the front end of the cover second edge 23 is defined as a cover third edge 24. The connecting portions of these edge portions are smoothly continuous.

  The cover second edge portion 23 and the cover third edge portion 24 are peripheral walls that are bent from the cover main body portion 21 toward the protector base 10 side. The dimensions of the cover second edge 23 and the cover third edge 24 in the vehicle width direction are set to be slightly larger than the outer diameter of the wire harness 3. The cover second edge portion 23 and the cover third edge portion 24 are provided with engagement recesses 25 for snap fit at every set interval so as to correspond to the engagement protrusions 15 provided on the protector base 10. ing.

  As shown in FIGS. 8 and 9, the dimension of the cover first edge 22 in the extending direction is set equal to the dimension of the base first edge 12 in the extending direction. The dimension of the cover second edge 23 in the extending direction is slightly shorter than the dimension of the base second edge 13 in the extending direction, and the dimension of the cover third edge 24 in the extending direction is the base third edge. 14 is set slightly shorter than the dimension in the extending direction. For this reason, when the protector cover 20 is overlapped with the protector base 10, the cover second edge 23 and the cover third edge 24 of the protector cover 20 are the base second edge 13 and the base third edge of the protector base 10. It is located slightly inside the portion 14. A dimension between the cover second edge 23 and the cover third edge 24 and the base second edge 13 and the base third edge 14 is defined as a gap dimension S. The gap dimension S corresponds to each of the first gap distance and the second gap distance.

Next, the assembly of the case 2 and the operation and effect of the power supply unit 1 will be described.
Next, assembly of the case 2 will be described.
As shown in FIG. 8, the case 2 includes a base first edge portion 12, a cover first edge portion 22, a base second edge portion 13, a cover second edge portion 23, and a base third edge portion 14. And the cover third edge 24 are made to correspond to each other, the protector base 10 and the protector cover 20 are brought close to each other so as to overlap each other. Note that the overlapping direction in this example coincides with the vehicle width direction.

  Here, the dimension of the cover second edge 23 in the extending direction is slightly shorter than the dimension of the base second edge 13 in the extending direction, and the dimension of the cover third edge 24 in the extending direction is the base third edge. Each dimension is set slightly shorter than the dimension in the extending direction of the portion 14. For this reason, when the protector cover 20 is superposed on the protector base 10, the protector cover 20 is inserted into the protector base 10. Thereby, the engagement convex part 15 and the engagement recessed part 25 which comprise a snap fit each engage. Thereby, the displacement to the direction which the protector base 10 and the protector cover 20 mutually spaces apart is controlled. Further, since the engagement convex portion 15 and the engagement concave portion 25 constituting the snap fit are provided so as to surround the plate surfaces of the base main body portion 11 and the cover main body portion 21, the plurality of engagement convex portions 15 and the engagement concave portions 15 are provided. By the cooperation of the mating recess 25, the displacement of the protector base 10 and the protector cover 20 in the plate surface direction (direction intersecting the overlapping direction) is also restricted.

  The cover second edge 23 and the cover third edge 24 of the protector cover 20 and the base second edge 13 and the base third edge 14 of the protector base 10 are separated by a gap dimension S.

  Here, as shown in FIGS. 5 and 6A, crushing ribs 16 are provided on the base second edge 13 and the base third edge 14 of the protector base 10. The protruding length S + of the crushing rib 16 is longer than the gap dimension S (S +> S).

  Therefore, as shown in FIGS. 6B and 9, when the protector base 10 and the protector cover 20 are attached, the tops of the crushing ribs 16, more precisely, the tops 17 a and 17 a of the first ribs 17. The top portion 18a is crushed and deformed. Thereby, in the vicinity where the crushing ribs 16 are provided, gaps provided between the cover second edge 23 and the cover third edge 24 and the base second edge 13 and the base third edge 14 are filled.

  Further, the cover second edge 23 and the cover third edge 24 that are in contact with the first rib 17 are directed away from the base second edge 13 and the base third edge 14, that is, the cover main body 21. The plate surface is elastically deformed so that it is slightly pressed and narrowed. Further, the cover main body portion 21 in contact with the second rib 18 is elastically deformed so as to be slightly pushed and expanded in a direction away from the base main body portion 11, that is, outward in the vehicle width direction.

  Each part of the protector cover 20 that is elastically deformed causes the protector base 10 and the protector cover 20 to be connected to each other by the cooperation of the elastic force to be elastically restored and the engaging convex part 15 and the engaging concave part 25 constituting the snap fit. The relationship is sandwiched in the width direction (overlapping direction), the front-rear direction (direction intersecting the overlapping direction), and the vertical direction (direction intersecting the overlapping direction).

  Note that the case 2 is attached to the slide door 4 as shown in FIG. 1 through a fastener that is inserted into a fastening hole that is appropriately provided in the protector base 10 and the protector cover 20.

  As described above, the protector base 10 and the protector cover 20 are held in the vehicle width direction, the front-rear direction, and the up-down direction, and thus the protector base 10 and the protector cover 20 are integrally displaced. For this reason, even if it attaches to a vehicle and the vibration by driving | running | working of a vehicle or opening / closing of the sliding door 4 is input into the case 2, the collision with the edge part of the protector base 10 and the edge part of the protector cover 20 does not generate | occur | produce easily. Therefore, it is difficult for abnormal noise accompanying the collision to occur.

  In addition, the position where the crushing rib 16 is provided is an intermediate position between the engaging convex portions 15 constituting the snap fit. Thereby, since the site | part which the protector base 10 and the protector cover 20 always contact is scattered on the whole outer periphery of both, the protector base 10 and the protector cover 20 do not collide more easily, and it is hard to generate noise.

  A gap dimension S is provided between the cover second edge 23 and the cover third edge 24 of the protector cover 20 and the base second edge 13 and the base third edge 14 of the protector base 10. Thus, the dimensions of each edge are adjusted. Thereby, it is easy to insert the protector cover 20 into the protector base 10. Therefore, it is easy to attach the protector base 10 and the protector cover 20 so as to overlap each other.

In addition, you may change the said embodiment as follows.
In the above embodiment, the first rib 17 and the second rib 18 are triangular prisms so that the top portions 17a and 18a are continuous in a linear shape, but the top portions do not have to be continuous in a linear shape. For example, a protrusion etc. may be sufficient. In addition, by employ | adopting the shape where the top parts 17a and 18a continue in linear form, it is easy to manage the protrusion dimension of the 1st rib 17 and the 2nd rib 18, and manufacture is easy. In addition, the shape of the crushing rib 16 does not need to be a triangular prism, and may be a semi-cylindrical shape or the like. Different shapes may be employed for the first rib 17 and the second rib 18.

  In the above embodiment, as shown in FIG. 10, the surface of the second rib 18 that is not continuous with the first rib 17, that is, the surface on the protector cover 20 side, is gradually increased toward the base body 11. It is good also as the inclined surface 19 which inclines so that protrusion length may become long.

By configuring in this way, the outer periphery of the protector cover 20 inserted into the protector base 10 is easily guided to the inner periphery of the protector base 10.
-In above-mentioned embodiment, although the crushing rib 16 had two, the 1st rib 17 and the 2nd rib 18, what is necessary is just to have any one.

  Further, the top portion 17a of the first rib 17 and the top portion 18a of the second rib 18 do not necessarily have to be continuous. In other words, the positions where the first ribs 17 and the second ribs 18 are provided may be different.

  In the above embodiment, the crushing rib 16 is provided at an intermediate position between the engaging convex portions 15 constituting the snap fit, but is not necessarily provided at the intermediate position. The crushing rib 16 may be provided near either one of the engaging convex portions 15 or may be provided so as to overlap the engaging convex portion 15. Further, a plurality of engagement projections 15 may be provided.

  -Although the snap fit was illustrated as an attachment part in the said embodiment, you may employ | adopt attachment parts other than this. In addition, if it is a snap fit, since both can be attached only by bringing the protector base 10 and the protector cover 20 close, assembling is easy.

In the above embodiment, the engaging convex portion 15 is provided on the protector base 10 and the engaging concave portion 25 is provided on the protector cover 20, but this relationship may be reversed.
In the above embodiment, the overlapping direction coincides with the vehicle width direction, but does not necessarily need to coincide. Therefore, the direction intersecting the overlapping direction need not be the vertical direction and the front-rear direction.

Next, the technical idea conceived from the embodiment and the other examples will be described.
(A) In the vehicular power supply unit having the above-described configuration, the first rib and the second rib are provided so that the respective leading ends thereof coincide with each other in the overlapping direction.
