Description

  The present invention relates to a tubular wire harness protector that houses and protects a wire harness routed in a vehicle or the like, and more particularly, to a wire harness protector that can be easily disassembled and taken out.

  In recent years, recycling of vehicle parts is also desired from the viewpoint of environmental protection, and the importance of wire harness recovery technology at the time of vehicle dismantling has increased. For example, for a wire harness routed in a vehicle, it is necessary to protect a necessary portion with a protector, and it is necessary to easily remove the wire harness from the protector.

  Usually, a protector for a wire harness is composed of a bowl-shaped protector main body that can accommodate the wire harness and a lid that closes the opening of the protector main body. With the wire harness accommodated, the lid is attached to the protector main body by a locking means. It is fixed. Therefore, when disassembling the vehicle, if possible, the wire harness is taken out by removing the locking means and opening the lid.

  However, removing the locking means is troublesome, and depending on the location where the locking means exists, the locking means may not necessarily be removed.

Therefore, as described in Patent Document 1 shown in FIG. 8, a hole 140 for hooking a hook such as a winch is provided in the protector 100 itself, the hook is hooked in the hole 140, and the wire harness W together with the protector 100 is forcibly attached. A method of peeling from the vehicle body has been proposed.
Japanese Patent Laid-Open No. 10-80037

  However, the method of forcibly peeling the wire harness W together with the protector 100 from the vehicle body with a winch or the like as described above requires a strong pulling device, and becomes a large-scale mechanism.

  As another method, it is conceivable to cut the peripheral wall of the protector with a cutter, open a part of the peripheral wall, and take out the wire harness from the open part. If the peripheral wall of the protector can be cut with a cutter, the protector can be opened without removing the lock, so that the wire harness can be easily taken out.

  However, the cutting operation with a cutter in a narrow place is not easy because there is a possibility that the cutter cannot be moved along a desired path.

  In consideration of the above circumstances, the present invention provides a protector for a wire harness that can easily cut a peripheral wall by using a cutting tool such as a cutter when disassembling a vehicle body, and can easily take the wire harness out. For the purpose.

  The invention according to claim 1 is a bowl-shaped protector body having a bottom wall and a pair of opposing side walls that stand up from both widthwise ends of the bottom wall and extend upward to secure an opening between the upper ends. In the protector for a wire harness having a lid body that is locked to the protector body in a covered state, a thin tear line extending continuously in the longitudinal direction of the protector is provided on each of the pair of opposing side walls, and each tear Parallel rail-shaped guide ribs for guiding the cutting tool are provided on the outer surfaces of the upper and lower side walls of the line.

  Invention of Claim 2 is a protector for wire harnesses of Claim 1, Comprising: When the said cover body is covered on the said protector main body so that opening may be plugged on the said cover body, the side wall of this protector main body An inner wall inserted inside and an outer wall inserted outside the side wall are provided.

  The invention according to claim 3 is the protector for wire harness according to claim 2, characterized in that a projection that engages between the upper and lower guide ribs is provided on the inner surface of the outer wall.

  A fourth aspect of the invention is the wire harness protector according to the third aspect, wherein any one of the protrusion and the guide rib is formed in a mountain shape in cross section.

  The invention according to claim 5 is the protector for wire harness according to claim 3 or 4, wherein the protrusion is selectively engageable between the guide ribs having different positions in the vertical direction. And

  According to the first aspect of the present invention, the side wall can be cut cleanly and easily along the tear line only by moving the tearing tool (cutter or minus driver) while being guided by the rail-shaped guide rib. That is, if only a thin tear line is provided on the side wall, the tear tool cannot be moved along the tear line well, but according to the present invention, the tear tool can be moved along the upper and lower guide ribs. Therefore, the side wall can be smoothly cut along the thin tear line without losing the tear line. Therefore, it is not necessary to pay special attention to follow the tear line, and even if it is a narrow and difficult place to work, it is necessary only by pulling the tear tool while guiding the guide rib, relying on the sense of the hand. The part can be easily cut. And by cutting the both side walls along the tear line, the protector can be opened greatly without opening the lid, and the wire harness can be easily taken out from the opened part. Demolition can be realized.

  In addition, the guide rib protruding from the outer surface of the side wall can be used when fixing or positioning the wiring harness to the wiring jig panel for wiring the wire harness. It can also be used for positioning when fixing to a vehicle). In addition, since the guide rib has a reinforcing action, the rigidity of the side wall can be increased. In addition, if the number of upper and lower and left and right guide ribs is different, it is possible to identify the vertical and horizontal directions.

  Moreover, since the tear line is a thin-walled part, it is possible to widen the opening between the upper ends of the side walls by utilizing the flexibility of the part, and by doing so, the wire harness is routed to the protector body. The workability at the time can be improved. For example, in the case of a protector with a narrow width between the side walls, it is difficult to insert the wire harness, but the opening of the wire harness can be widened to facilitate the insertion of the wire harness. In addition, at that time, the guide ribs interfere with each other, so that excessive bending can be restricted.

  In addition, since the height of the protector body can be reduced by bending the pair of side walls inward with a thin tear line, the amount of packing material when the protector body is packed can be reduced. In this case, the side wall can be folded to a lower height if the thin tear line is provided as close to the bottom wall as possible.

  According to the invention of claim 2, since the side wall of the protector main body is sandwiched between the inner wall and the outer wall provided on the lid, the side wall of the protector main body that is easily bent due to the thin tear line is prevented. Can be done and the side walls can be reinforced. In particular, when the side wall of the protector body is bent inward at the time of packaging, the side wall may be bent, but the bent can be corrected by the inner wall.

  According to the invention of claim 3, the lid body can be locked to the protector body by engaging the protrusions on the inner surface of the outer wall of the lid body between the guide ribs on the outer surface of the side wall of the protector body. Therefore, it is possible to omit another locking means.

  According to the invention of claim 4, since either the lid-side protrusion or the guide rib that engages between the guide ribs is formed in a mountain-shaped cross section, the protrusion is engaged between the guide ribs by the action of the slope of the mountain-shaped cross section. It is easy to disengage.

  According to the fifth aspect of the present invention, the fitting amount of the lid body with respect to the protector body can be adjusted by changing the meshing position (engagement position) between the protrusion and the guide rib. Therefore, rattling of the wire harness can be prevented by setting an optimal fitting amount according to the diameter of the wire harness.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  That is, if only the thin tear line 12a is provided on the side wall 12, the tear tool M cannot be moved well along the tear line 12a. However, in this protector, the tear tool is cut along the upper and lower guide ribs 13. Since M can be moved, the side wall 12 can be smoothly cut along the thin tear line 12a without detaching the tear line 12a.

  Therefore, it is not necessary to pay special attention to follow the tear line 12a, and even in a narrow and difficult place to work, it is possible to simply pull the tear tool M while guiding the guide rib 13 while relying on the sense of the hand. The necessary part can be easily cut.

  And as shown in FIG. 4, the upper part of a protector can be open | released largely, without opening the cover body 20 by cutting the both-sides wall 12 along the tear line 12a. Therefore, the wire harness can be easily taken out from the opened portion, and easy disassembly can be realized.

  In addition, the guide rib 13 protrudingly provided on the outer surface of the side wall 12 can be used for fixing and positioning to a wiring jig board for wiring the wire harness, and the wire harness is mounted on the vehicle ( It can also be used for positioning when the protector is fixed to the vehicle. In addition, since the guide rib 13 has a reinforcing action, the rigidity of the side wall 12 can be increased. Further, if the number of the upper and lower or left and right guide ribs 13 is different, it is possible to identify the upper, lower, left and right directions.

  Moreover, since the tear line 12a is a thin part, it is also possible to widen the opening between the upper ends of the side walls 12 by utilizing the flexibility of the part, and by doing so, the wire harness is connected to the protector body 10. Workability at the time of routing can be improved. For example, as shown in FIG. 5, in the case of a protector with a narrow width between the side walls 12, it is difficult to insert the wire harness, but the opening of the wire harness can be widened to facilitate the insertion of the wire harness. In addition, when the guide ribs 13 interfere with each other, excessive bending can be restricted.

  Further, as shown in FIGS. 6A and 6B, the height of the protector body 10 can be reduced by bending the pair of side walls 12 and 12 inward (in the direction of arrow B) with a thin tear line 12a. And the quantity of the packing material at the time of packing the protector main body 10 can be reduced. In this case, the side wall 12 can be folded to a lower height if the thin tear line 12a is provided as close to the bottom wall 11 as possible.
