Description

  The present invention relates to a protector for a wire harness routed in an automobile.

A large number of wire harnesses are routed in an automobile, and a protector made of a resin molded product is externally attached to the wire harness at a required location in order to protect the wire harness and guide the route of the wire harness.
The protector is composed of a bowl-shaped main body and a lid that is put on the wire harness after the wire harness is inserted into the main body and lock-coupled, and has a closed cross section after the lid is attached. The wiring position of a specific electric wire may be prescribed | regulated among the electric wire groups of the wire harness inserted in a protector. For example, it is specified not to wire an important wire such as an air bag system at a location where the volume is partially reduced in the protector and pressure is easily applied to the wire to be wired. However, after the lid is lock-coupled to the protector main body, the wiring state of the important electric wires in the protector cannot be confirmed.

  In addition, after the protector lid is locked to the main body and fixed to the vehicle body, wires such as cables, harnesses, hoses, etc., to be routed later cannot be inserted into the protector, and they are packaged separately and wired in a separate route. There is a need. For example, after a protector that covers a wire harness routed on a floor panel is fixed to a vehicle body, a parking cable, an opener cable for a fuel tank lid, a luggage opener cable, a hood opener cable, a washer hose, and the like are wired.

  In the protector described in Japanese Patent Application Laid-Open No. 2005-287122 that has been proposed in the past, as shown in FIGS. 5A and 5B, along the outer surface of the side wall 101 of the main body 100, a linear shape made of a washer hose or an electric wire. The second accommodation grooves 102 through which the body W is inserted are arranged in parallel so that the first accommodation grooves 105 provided in the main body 100 and the wire material to be post-wired can be wired in parallel. Further, the lock coupling portion between the lock claw 111 provided on the lid 110 that is locked to the main body 100 and the lock frame 106 provided on the main body side wall 101 is disposed in the upper surface opening of the second accommodation groove 102, so that the second The linear body W wired in the receiving groove 102 is configured to prevent upward slipping.

  As described above, when the second receiving groove is inserted in parallel on the outer surface of the protector, the rear wiring line can be inserted, and the rear wiring cable can be confirmed from above. Is possible.

JP 2005-287122 A

If the second receiving grooves shown in FIG. 5 are arranged so as to protrude from the outer surface of the main body, the width of the protector is widened and the protector cannot be installed when the space for arranging the protector is narrow. Moreover, the 2nd accommodation groove is not closed with the lid | cover only by utilizing the lock | rock coupling | bond part of a main body and a lid | cover as a retaining. Therefore, there is a risk that a sharp external interference material may pierce the electric wire wired in the second accommodation groove and damage the electric wire. In particular, the important electric wire cannot be inserted into the second accommodation groove that is not closed by the lid.
Further, if a linear body made of a thin electric wire or the like is inserted into the second accommodation groove, there is a risk of jumping upward due to vehicle vibration. When the linear body is thick and is securely prevented by the lock coupling portion, the thick linear body cannot be inserted into the second receiving groove from above, and the protector in the length direction from one end to the other end The insertion workability of the linear body to be wired later is deteriorated.

  The present invention has been made in view of the above problems, and the main problem is that when it is necessary to specify a wiring position in a group of electric wires inserted into the protector, the wiring position is locked to the main body after the lid is locked. It is to be able to confirm from.

In order to solve the first problem, the present invention comprises a bowl-shaped main body, and a lid that is covered and locked after inserting a wire harness into the main body,
A partition that divides the passage in the main body in the width direction protrudes from the upper surface of the bottom wall of the main body, and the electric wire inserted into the passage partitioned by the partition is visible on the lid or the side wall of the main body The protector for wire harnesses provided with the through hole is provided.

  If a partition is provided and the passage is divided as described above, the required wire is required by looking inside from the lid above the wire passage where the wiring position needs to be confirmed or the through hole provided in the side wall of the main body. You can confirm that you are wiring to the route. For example, it is preferably used when only the airbag-type electric wire is distinguished from other electric wires and passed through one wiring passage and the other electric wire group is passed through the other wiring passage.

  The protector includes a trunk line insertion portion for inserting a trunk line of a wire harness and a branch line insertion portion branched from the trunk line insertion portion, and the partition line and the through hole are provided in the branch line insertion portion and / or the trunk line insertion portion. ing.

Further, the protector according to the present invention is provided with a wire insertion groove that is rear-routed on the surface of the lid after the lid is locked to the main body, and the wire insertion groove does not protrude from the lid surface in a state where the wire is inserted. Preferably, the through hole is provided in the bottom wall of the wire rod insertion groove, and the pressing claw is protruded from the inner peripheral surface of the opposing position across the opening of the wire rod insertion groove.
Examples of the wires to be routed later include the parking cable, an opener cable for a fuel tank lid, a luggage opener cable, a hood opener cable, a washer hose, and a plurality of separate wire harnesses.

  The protector is assembled in advance in a state where the wire harness is inserted into the internal insertion passage surrounded by the lock-coupled main body and the lid, and is attached to the automobile in this state, and is inserted into the wire insertion groove provided on the lid surface of the protector after the attachment. is doing. Since the wire insertion groove is formed by recessing the lid and bulging toward the main body, it can be installed in the space where the protector has been conventionally arranged without increasing the outer shape of the protector. Also, the depth of the wire rod insertion groove does not cause the wire rod to be rearranged from projecting from the insertion port of the insertion groove opening on the lid surface, and even if it is likely to jump out of the opening due to vibration during automobile travel, Since the claw is protruding, it can be prevented from popping out.

  The wire insertion groove provided in the lid is provided to bulge toward the main body side on one side in the width direction of the lid, and protrudes from the partition wall that divides the bulge side and the non-bulge side of the wire material insertion groove into the main body. The wire rod insertion groove bulges to the main body side with a projection amount of 1/2 or more of the depth of the main body, and the wire harness is inserted into the wire passage with the lower portion of the wire rod insertion groove on the non-bulge side as a wiring passage; It is preferable to perform parallel wiring with the wire rod to be rear-routed in the wire rod insertion groove on the surface of the lid.

When the wire rod insertion groove is provided in the lid of the branch wire insertion portion, the volume of the wiring passage is reduced, but a branch wire insertion passage with a small number of wires to be inserted can be secured.
In addition, since the volume of the lower part of the bulging portion of the wire insertion groove is reduced, an electric wire (such as an air bag-type electric wire) that needs to avoid a pressing force load is a non-bulging side main body passage partitioned by the partition wall. The wire can be inserted into the wire to ensure protection of the electric wire.

  Further, if a through hole is provided in the bottom wall of the wire insertion groove provided in the lid, after the lid is locked to the main body, the wire is routed through the through hole from the top of the lid to the passage below the through hole. You can check whether or not. For example, if it is set not to wire the airbag-type yellow exterior wire below the wire rod insertion groove, it can be detected that the wiring of the airbag-type wire is located below the through hole. .

  In addition, when it is an electric wire which does not need to confirm the electric wire penetrated in the main body under the said wire rod insertion groove, it is not necessary to provide the through hole used as a peep hole in the said wire rod insertion groove. Therefore, only the wire insertion groove to be wired later is provided on the lid surface.

  In the protector of the present invention, when a fixing clip is projected from the bottom wall bottom surface of the main body that is in a position opposite to the through hole provided in the lid, the through hole is used as an insertion hole for a jig for releasing the fixing of the clip. Can be used together.

  As described above, in the protector according to the present invention, after the wire harness is inserted into the main body, the lid is put on and locked, the electric wire inserted into the protector is accommodated through a predetermined passage in the protector. Can be easily confirmed through a through hole provided in a lid or the like.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The protector of 1st Embodiment is shown to FIG. 1 (A) (B) (C).
The protector 1 is composed of a bowl-shaped main body 2 and a lid 3 that is covered and locked after the wire harness is inserted into the main body 2. The main body 2 has side walls 2 b and 2 b erected from both edges in the width direction of the bottom wall 2 a, and a thin hinge portion 4 is provided between one side wall 2 b and one side edge of the lid 3. The main body 2 and the lid 3 are integrally formed by connecting one side edge via the thin-walled hinge portion 4, and a lock frame 2 x and a lock claw 3 x are provided on the other side edge, and the wire harness is inserted and locked. .

  A partition wall 8 protrudes from the upper surface of the bottom wall 2a of the main body 2 of the protector 1, and the wiring passage is divided in the width direction to be divided into passages 9A and 9B. The partition wall 8 may be provided partly in the length direction of the protector, or may be provided partially at intervals, or may be provided over the entire length. Only one important wire, for example, an airbag-type yellow exterior wire w1 is wired in one of the divided passages 9A, and another wire w2 of the wire harness is wired in the other passage 9B.

  A through hole 5 is provided in the upper wall of the lid 3 that is located above the passage 9A, and the electric wire w1 passing through the passage 9A can be confirmed by looking down from directly above the through hole 5. The through hole 5 is preferably as small as possible, but has a size that allows the entire width direction of the passage 9A to be seen through the through hole 5 to every corner.

  Since the protector 1 having the above-described configuration is provided with the through hole 5 in the lid 3, the wire harness 10 is inserted into the main body 2 after the wire harness 10 is passed through the main body 2 and the lid 3 is locked to the main body 2. The wiring state of the wire of the harness 10, for example, confirming that the airbag-type wire w <b> 1 is wired in the passage 9 </ b> A and is partitioned from the other wires w <b> 2 by looking into the passage 9 </ b> A from directly above through the through hole 5. be able to.

  In addition, after looking through the through hole 5 and confirming the wiring state, it is preferable to close the through hole 5 by adhering an adhesive tape to the surface of the lid 3 where the through hole 5 is provided.

FIG. 2 shows a modification of the first embodiment.
In this modification, instead of providing a through hole in the lid 3, a through hole 5 is provided in one side wall 2b of the main body 2 surrounding the passage 9A. In this way, by looking into the main body 2 from the through hole 5 provided in the side wall 2b, it can be confirmed whether or not a predetermined electric wire is wired in the passage 9A.

3A and 3B show a second embodiment of the present invention.
The protector 1 including the main body 2 and the lid 3 has a T shape as a whole, and includes a trunk line insertion part 1A on the horizontal axis side and a branch line insertion part 1B branched from the middle of the trunk line insertion part 1A. The trunk line 10A of the wire harness 10 is inserted into the trunk line insertion part 1A, and the branch line 10B branched from the trunk line 10A is inserted into the branch line insertion part 1B.

  As shown in FIG. 3B, the cross-sectional shape of the branch line insertion portion 1B has a relatively shallow bottom and a wide width direction. The branch line insertion portion 1B has a portion in which a recess 3c is provided on one side in the width direction of the lid 3 in order to avoid interference with an external interference material (not shown) in a part of the length direction. The recess 3c is provided with a through hole 5 through which the lower part can be seen.

On the other hand, the main body 2 of the branch line insertion portion 1B includes a width side on the bulging side of the depression 3c from the bottom wall 2a at a position corresponding to the depression 3c, and the other side in the width direction on the non-bulging side. A partition wall 8 for partitioning is projected. The bulging side passage 9B defined by the partition wall 8 is a passage through which no electric wire is inserted. The passage 9A on the non-bulging side is a passage through which an electric wire such as an important electric wire passes. In addition, when there are few branch lines 10B which penetrate the branch line insertion part 1B, all the branch lines 10B are inserted in the said channel | path 9A.
The reason why the side of the passage 9A is used as the branch wiring passage as described above is that the recess 3c bulges out in the passage 9B, and there is a risk of pressing the electric wire by the recess 3c.

  Also in the protector 1, after the wire harness 10 is passed through the main body 2 and the lid 3 is locked to the main body 2, the branch wire 10B is not wired to the passage 9B of the branch wire insertion portion 1B. You can check it out.

The wire insertion groove 15 is a groove into which the cable 11 of the rear wiring line is inserted after the protector 1 is fixed to the vehicle body, and protrudes so as to bulge out toward the main body 2 as shown in FIG. Yes.
In the present embodiment, there is one cable 11 to be inserted into the wire rod insertion groove 15, and in a state where the cable 11 is inserted into the wire rod insertion groove 15, the cross-sectional arc shape has a volume that prevents the cable 11 from protruding from the surface 3 a of the lid 3. Yes.
And the control claw 6 (6A, 6B) protrudes from the inner peripheral surface of the opposing position that sandwiches the insertion opening of the upper end opening of the wire rod insertion groove 15 with an interval in the length direction.

The cross-sectional shape of the branch wire insertion portion 1B is a horizontally long shape with a relatively shallow bottom and a wide width direction as shown in FIG. It extends in the direction.
A through hole 5 is provided at the bottom of the wire rod insertion groove 15. The through hole 5 has a long hole shape in this embodiment. Similar to the first embodiment, the through hole 5 serves as a peephole for confirming the wiring state of the branch line 10B inserted into the branch line insertion portion 1B. The smaller the through hole 5, the better. However, the size is such that the passage 9B can be seen from every corner. When the cable 11 is inserted into the wire insertion groove 15, the through hole 5 serving as a peep hole can be hidden.
Further, when a fixing clip (not shown) is projected from the lower surface of the main body bottom wall 2a of the branch line insertion portion 1B, the through hole is used as an insertion hole for a clip locking release jig. can do.

In the main body 2 of the branch line insertion portion 1B, a partition wall 8 is erected from the center in the width direction of the bottom wall 2a at a position facing the through hole 5 provided in the lid 3, and the branch line insertion portion 1B is extended in the width direction. Divided into two. The partition wall 8 may be provided at a required portion, but may be provided over the entire length in the length direction of the branch line insertion portion 1B.
Of the passages divided by the partition wall 8, the bulging-side passage 9B in which the wire insertion groove 15 bulges downward and the volume is reduced is not used as the branch passage, but the other passage on the non-bulging side. 9A is used as an insertion path for the branch line 10B.

  It can be confirmed through the through hole 5 that the branch line 10B is not inserted into the passage 9B. In addition, the cable 11 that is inserted and wired in the wire insertion groove 15 on the surface of the lid 3 and the branch line 10B that is wired in the passage 9A surrounded by the lid 3 and the main body 2 are wired in parallel to provide a protector. 1 branch line insertion portion 1B can be flattened.
