Description

  The present invention relates to a protector for a wire harness, and more particularly, to a protector for inserting and protecting a wire harness routed in a vehicle, and fixing the wire harness to the protector with good workability.

The wire harness routed in the automobile is inserted into a protector made of a resin molded product for the purpose of protecting the electric wire group from the path regulation and the external interference material.
The protector has a substantially bowl shape provided with a passage of an electric wire group surrounded by a bottom wall and both side walls, projects a tape-wrapped tongue piece from the bottom walls at both ends in the length direction, and the tape-wrapped tongue piece and the wire Adhesive tape is wrapped around the group to secure the wire group to the protector.

  When the wire group that constitutes the wire harness inserted into the protector is inserted through the protector at the entrance portion of the protector, the wire group that is routed from a different route is branched out to the different route. Therefore, when fixing each at the exit part, when changing the path inside the protector, inserting it, inserting the main wire group into the protector, and branching out the branch line from the main line, insert inside the protector in a separate process There are various forms.

  For example, in the protector proposed in Japanese Utility Model Laid-Open No. 2-26321, as shown in FIG. 9, when the branch line 102 is branched and pulled out from the trunk line 101 of the wire harness inserted through the protector 100, the outlet 100a of the trunk line 101 and Separately, a branch line outlet 100c is provided in the vicinity of the outlet of the side wall 100b, a tape winding tongue piece 100d is provided at the branch line outlet 100c, and an adhesive tape T is wound around the branch line 102 and the tape winding tongue piece 100d to be fixed to the branch line outlet 100c. Yes.

As described above, in order to branch and pull out the branch line 102, if the branch line outlet 100c provided with the tape winding tongue piece 100d is provided protruding from the side wall 100b, the shape of the protector 100 becomes complicated and large, and the installation space is increased. There are problems such as being easily subject to restrictions.
In addition, depending on the vehicle type, the branch line 102 may not be branched from the main line 101. In this case, if the protector 100 is shared, useless space will be taken due to the presence of the protruding branch line exit.

  Instead of providing the branch line outlet on the side wall of the protector described above, a partition wall may be erected at the outlet portion of the protector to divide the passage, and a tape winding tongue may be provided at the outlet of each passage. With this configuration, there is an advantage that the protector can be downsized rather than the branch line outlet projecting from the side wall.

  For example, as shown in FIGS. 10A and 10B, when the first wire group 120 and the second wire group 121 that take different routing routes are passed through the protector 130, the partition walls 130 a are respectively provided at the entrance and exit of the protector 130. , 130b is erected from the bottom wall 130c, and two divided wire passages 131 and 132 are provided. In addition, tape winding tongue pieces 131a and 131b and 132a and 132b are provided so as to be arranged adjacent to each other from the opening end of the bottom wall at the entrance / exit for each passage.

  As described above, when the tape winding tongues 131a and 132a are arranged adjacent to each other on the inlet side and the tape winding tongue pieces 131b and 132b are arranged adjacent to each other on the outlet side, when the tape winding operation is performed on one side, the other interferes. It becomes very difficult to do. In particular, when the tape winding operation is performed in a separate process, such as when tape winding through the wire group at the time of wire harness assembly to one tape winding tongue piece, and the other is to wind the tape by inserting the wire group in the automobile assembly line, The portion that has been wound on the tape interferes with the subsequent tape winding operation, making winding very difficult.

In addition, as shown in FIG. 10C, depending on the vehicle model, the first wire group 120 may be inserted through only one passage 131 and the second wire group 121 may not be inserted through the passage 132.
Furthermore, as shown in FIG. 10 (D), it may be inserted into the passage 131, the route is changed at an intermediate position, and pulled out from the passage 132.
As shown in FIGS. 10C and 10D, when the electric wire group is tape-wound only with one tape winding tongue piece among the two tape winding tongue pieces arranged in parallel, the other tape winding tongue piece becomes unnecessary. And since it is unnecessary, since the tape winding tongue piece is located in a line, there exists a problem that the tape winding operation | work to one tape winding tongue piece is difficult to do.

Japanese Utility Model Publication No. 2-26321

  The present invention has been made in view of the above problems, and in the case where a partition wall is provided in the protector to divide the passages, both of them are provided without protruding tape-wrapped tongues side by side from the bottom wall of each passage. When the wire group is inserted into one of the passages, when the wire group is inserted into one of the passages, or when the wire group is inserted into both passages in a separate process, the wire harness protector can be applied to various forms. The task is to make the fixing work easy.

In order to solve the above problems, the present invention is a protector in which an electric wire passage is formed by a bottom wall and side walls protruding from both end edges in the width direction of the bottom wall,
A partition wall that divides the electric wire passage is erected on the distal end side in the length direction of the bottom wall, the partition wall extends outward from the distal end, a fixing piece for fixing the electric wire group is provided, and the partitioned A protector for a wire harness is provided in which a fixed piece is not protruded from an opening end of a bottom wall of an electric wire passage.

As described above, the protector of the present invention uses the partition wall that partitions the electric wire passage, and extends the partition wall so as to protrude outward from the longitudinal end of the protector. A fixing piece is provided as an attachment piece.
When the fixing piece is an attachment piece for a fastening band, a band through hole is provided, and the band is fastened to the electric wire group through the fastening band. When winding the tape, the fixing piece and the electric wire group are attached by winding an adhesive tape.

In the protector of the present invention, when a wire group is inserted into the wire passages on both sides, a band piece of one fastening band is wound and fastened around the wire groups on both sides, or an adhesive tape is sandwiched between the fixing pieces. Then, continuously wind the outer circumference of the wire group on both sides and fix it with tape.
Moreover, the electric wire group of the electric wire channel | path of any one side of the said fixing piece is being fixed with the fastening band adhesive tape.

As described above, in the present invention, the fixing pieces formed of the tape-wrapped tongue pieces are not arranged adjacent to the bottom wall of the protector, but are formed by extending the partition walls at the boundary positions of the passages divided by the partition walls. A piece is provided. Since the fixing piece protrudes from the boundary position of the both-side passage, the electric wire group to be inserted into the passage on both sides can be fixed using one fixing piece, and when the electric wire group is inserted only into one of the passages, The wire group can be fixed using the fixing piece.
In addition, it is possible to eliminate the difficulty of performing the tape winding operation that occurs when the tape winding tongue piece is provided side by side from the conventional bottom wall.

  The protector is not limited to dividing into two passages by one partition wall, and when dividing into three passages by providing two partition walls, further dividing into four passages by providing three partition walls. In such a case, the partition wall may be extended from the opening end to be a fixed piece.

Furthermore, the present invention is a protector in which an electric wire passage is formed by a bottom wall and side walls protruding from both end edges in the width direction of the bottom wall,

In the protector having the above-described configuration, since the fixing pieces are provided by protruding the side walls on both sides, the fixing pieces on both sides are located apart from each other, and the electric wire group is fixed to one fixing piece by winding a tape or a fastening band. During the work, the other fixing piece does not interfere, and the electric wire group can be fixed with good workability.
The fixing piece may be a flat plate projecting only from the side wall, or may be a fixing piece having an L-shaped cross section by extending the corner of the bottom wall along the side wall. Also in this case, since the portion protruding from the bottom wall is dimensioned, the other fixing piece does not get in the way when the wire harness is attached to one fixing piece.

In any of the protectors of the present invention, the partition wall is erected on both sides in the length direction of the bottom wall, the fixing pieces are provided so as to project from the partition walls on both sides, and the central portion of the bottom wall is provided. It is preferable that the passage of the electric wire group can be changed without providing a partition wall.
In addition, the protector may be covered with a lid that closes the upper surface opening, or the tape is wrapped around the outer periphery of the protector, the upper surface is covered with the tape, and the tape that prevents the wire group housed inside the protector from being wrapped is prevented. May be.
When a lid is provided, the lid may be molded integrally with the protector, and the lid may be connected via a thin hinge, or the lid may be molded separately.

  As described above, in the protector provided with the partition wall for dividing the passage of the present invention, the partition wall extends outward from the opening end instead of protruding the tape winding tongue piece from the opening end of the bottom wall for each passage. Because it is a fixed piece, when the wire group is inserted into the passages on both sides, when the wire group is inserted through only one of the passages, the wire group is fixed with tape or a fastening band using the fixed piece Can be fixed to the protector with good workability.

  In addition, when the fixed piece is projected with the side wall extended, the relatively large size is provided between the side walls. Therefore, when the electric wire group is attached to one fixed piece, the other fixed piece is obstructive. Can be prevented.

Hereinafter, embodiments of a protector of the present invention will be described with reference to the drawings.
The protector of 1st embodiment is shown in FIG. 1 thru | or FIG.

The protector 1 is made of a resin molded product. As shown in FIGS. 1A and 1B, the protector 1 includes a bottom wall 2, and side walls 3 and 4 projecting from both end edges in the width direction of the bottom wall 2, thereby It is formed and has a bowl shape with a long length L.
