Description

  The present invention relates to a wire harness wiring direction restricting material, and in particular, restricts interference with an external interference material in a cross wiring region of the wire harness.

  For example, in an engine traverse part that routes a wire harness from an automobile body to an engine, as shown in FIG. 9, the wire harness W is fixed to the vehicle body panel P and the engine E with clips 1 and 2, respectively. Curved in the space. In this engine rubber section, the wire harness vibrates as the engine E swings, so that the extra length is provided between the fixing points of the clips 1 and 2.

  After being manufactured, the wire harness W is stored in a wound state and transported to a car maker, and is assembled in an automobile. In many cases, the wire harness W is bent before being installed in the automobile. In the wire harness provided with the extra length as described above, how to meander and route in the automobile is difficult, but it is difficult to predict, and the swing width of the harness W due to the swing of the engine E is also considered. There is a need. Therefore, as indicated by a dotted line in the figure, it is necessary to secure a meandering space around the wiring line of the harness W in advance.

  However, there is a problem in that the layout of the peripheral component 3 is restricted by securing a meandering space for the wire harness W in a narrow engine room. Further, if the wire harness W bends unexpectedly and interferes with peripheral equipment (external interference material), and it is repeated according to vibration, there is a risk of disconnection.

On the other hand, various protectors have been proposed as members for the purpose of harness protection and wiring direction regulation.
For example, in Japanese Utility Model Laid-Open No. 4-101216 (Patent Document 1), as shown in FIGS. 10A and 10B, a first focusing member 4A and a second focusing member in which a plurality of focusing portions 5 are connected at a predetermined interval. 4B, and the locking projection 7b formed on the connecting portion 6b of the second focusing member 4B is inserted and locked into the locking hole 7a formed on the connecting portion 6a of the first focusing member 4A. There is provided a protector 4 that connects the second converging members 4A and 4B and inserts a harness 9 therein to condense. In the protector 4, the locking projection 7 b is locked in the locking hole 7 a so as to be relatively movable in the arrangement direction of the converging portions 5.

  As shown in FIG. 10 (B), the protector 4 locks and fixes the clip 8 protruding at both ends in the length direction of the first focusing member 4A to a fixing member (not shown). However, it is said that the harness 9 can be easily bent and routed by relatively moving in the locking hole 7a.

If the harness 9 is curved and routed in the engine traverse portion using this protector 4, the routing direction can be regulated and it is considered unnecessary to secure the harness meandering space. However, it is considered that the protector 4 is easily separated from the harness 9 when the first converging member 4A and the second converging member 4B are easily separated and subjected to severe vibration. In addition, the protector 4 covers the harness 9 over the entire length of the bent portion, and the harness 9 becomes thicker when the protector 4 is attached.
Furthermore, the protector 4 is easy to bend two-dimensionally on either the first focusing member 4A side or the second focusing member 4B side, but it is curved and arranged three-dimensionally. It is difficult to do, and there are restrictions on the routing design.

Japanese Utility Model Publication No. 4-101216

  The present invention has been made in view of the above problems, and by restricting the wiring direction of the wire harness to a required curved path, the harness disconnection due to swinging is prevented, and the wire harness meanders around the wiring path. There is no need to secure a space, and it is an object of the present invention to provide a wiring harness routing direction regulating material that can improve space saving and routing design freedom.

In addition, since it is not necessary to secure a meandering space for the harness around the required routing route, it is possible to contribute to space saving and increase the degree of freedom in designing the layout of peripheral devices.

  In addition, the band part that spans the outer periphery of the wire harness is merely provided at a predetermined interval in the band material, and the influence of the bending deformation of the band material can be absorbed at the band part non-formation place. Each band portion can maintain a stable lock connection against vibration and bending deformation of the band member, and the band member can be bent not only in the two-dimensional direction but also in the three-dimensional direction such as the torsional direction. It can cope with various wiring designs of wire harnesses. Moreover, the thickening of the wire harness due to the installation of the wiring direction regulating material can be suppressed.

  The clip has a shaft portion protruding from a base provided on the back surface of the band material at both ends in the length direction, and a folded blade portion is projected on both sides from the shaft portion tip. It is preferable that a locking step portion is provided and the locking step portion is locked and fixed to an inner peripheral surface of a locking hole provided in the fixing member.

With the rib, the bending of the harness to other than the required route can be reliably regulated, and the swing width of the harness can be minimized, so that more accurate routing design and peripheral device layout design are possible.

  The band material where the band part is provided is provided with a support wall protruding from both ends in the width direction to provide a recess for penetrating the wire harness, and the band is provided at the tip of one support wall via a thin hinge. The locking portion made of a locking claw may be provided at the tip of the band, and the locked portion made of a lock frame may be provided at the tip of the other support wall.

  As described above, according to the present invention, since the wiring direction of the wire harness can be regulated to a required curved wiring direction, it is possible to prevent disconnection of the harness caused by bending or swinging the wire harness in an unexpected direction. In addition, since it is not necessary to secure a meandering space for the harness around the required routing route, the space can be used effectively and the degree of freedom in the layout design of peripheral devices can be increased.

  In addition, since the band part that spans the outer periphery of the wire harness is provided at a necessary interval in the band member, the band part is not easily unlocked even if it is subjected to vibration or the band member is bent and deformed, and Since the material can be bent not only in the two-dimensional direction but also in a three-dimensional direction such as a twisting direction, it is possible to increase the degree of freedom in wiring design of the wire harness. Furthermore, the thickening of the wire harness due to the installation of the routing direction regulating member of the present invention can be suppressed, and from this point, it is possible to cope with space saving.

It is connected to the upper end of one support wall 12 through a thin hinge 16 so that it can be opened and closed in the circumferential direction of the wire harness.
A lock claw 17 is formed at the tip of the band portion 15, and a lock frame 18 for locking the lock claw 17 is formed at the upper end of the other support wall 13.

Of the wire harness penetrating recesses 14, the wire harness penetrating recesses 14 </ b> A formed at both ends in the length direction of the strip 11 are corrugated on the inner peripheral surface thereof as shown in FIGS. 1 and 3B. A rib 19 that fits into the valley portion Ta of the tube T is projected in an arc shape.
In addition, ribs 20 that fit into the valley portions Ta of the corrugated tube T are also provided on the inner peripheral surfaces of the band portions 15 </ b> A formed at both ends in the length direction of the band material 11. .

  As shown in FIG. 4, the clip 21 includes a base 22 that is integrally provided on the back side of both ends in the length direction of the strip 11, and a shaft portion 23 that protrudes from the back side of the base 22. And a blade portion 24 that is folded back from the tip of the shaft portion 23 to both sides. A locking step portion 25 is formed at the tip of the blade portion 24.
