Description

Technical Field

[0001] The present invention relates to a branch protection member and a branch protection member with a wire harness.

Background Art

[0002] As a branch protection member for protecting a branch portion of a wire harness, for example, wire harness protection materials of Patent Documents 1 and 2 have been proposed. The wire harness protection material of Patent Document 1 is composed of an upper case and a lower case that protect a branch portion. Further, insertion holes for inserting branch wires of the wire harness are formed on the side surfaces of the upper case and the lower case by butting against each other. On the inner surface of the insertion hole, a groove portion that fits with a corrugated tube covering the branch wire is provided so that the branch wire does not shift in position. However, in the wire harness protection material of Patent Document 1 described above, since the diameter of the insertion hole is predetermined, there is a risk that the branch wire cannot be inserted into the insertion hole depending on the diameter of the branch wire, and the applicable branch portion is restricted, resulting in poor versatility.

[0003] The wire harness protection material of Patent Document 2 is composed of a substrate and a cover plate that sandwich a branch portion, and a plurality of connecting portions that connect these substrate and cover portions with a space therebetween. The branch wire of the wire harness is led out of the space between the connecting portions to the outside between the substrate and the cover plate. However, the wire harness protection material of Patent Document 2 has a problem that there is no structure for preventing the displacement of the branch wire, and displacement occurs.

Embodiments for Carrying out the Invention

[0010] Specific embodiments of the present invention will be described below with reference to each figure.

[0011] As shown in FIGS. 1 and 2, the branch protection member 1 with a wire harness includes a wire harness WH and a branch protection member 2 that protects the branch portion WHd of the wire harness WH.

[0012] In this embodiment, as shown in FIG. 2, an example will be described in which a branched portion WHd of a wire harness WH, where eight branch wires Wb branch off from a main wire Wt, is the object to be protected.

[0013] The branch protection member 2 includes a base 3 (first plate portion), a lid 4 (second plate portion), a column portion 5, and a plurality of wall portions 61 to 66. The base 3, the lid 4, the column portion 5, and the plurality of wall portions 61 to 66 are preferably each formed of a synthetic resin material such as PP (polypropylene).

[0014] As shown in FIGS. 1 and 2, the base 3 and the lid 4 position the branched portion WHd of the wire harness WH between them. Also, as shown in FIGS. 3 to 5, the base 3 and the lid 4 are provided with the same size and the same shape, and are formed in a disc shape in this embodiment. Note that the shapes of the base and the lid 4 are not limited to circular, and may be square or the like. The diameters of the base 3 and the lid 4 are set to be larger than the branched portion WHd of the wire harness WH.

[0015] The column portion 5 is provided in a substantially cylindrical shape, and as shown in FIG. 4, stands upright from the center of the disc-shaped base 3 toward the lid 4. As shown in FIG. 1, the base 3 and the column portion 5 are composed of separate parts, and the column portion 5 is provided by being fitted into the base 3. More specifically, a cylindrical mounting boss 31 that is fitted into one end of the column portion 5 stands upright at the center of the base 3. A lower recess 51 (second insertion hole) into which the mounting boss 31 is fitted is provided at the end of the column portion 5 on the base 3 side (lower side). An upper recess 52 that fits into the lid 4 described later is provided at the end of the column portion 5 on the lid 4 side (upper side).

[0016] Also, a through hole 32 (first insertion hole) into which a cylindrical mounting boss 7 (protrusion) for attaching to the vehicle body is fitted and inserted is provided at the center of the base 3. The through hole 32 is provided to penetrate from the lower surface of the base 3 to the upper surface of the mounting boss 31. The mounting boss 7 is provided to be approximately the same length as the through hole 32, and when fitted into the through hole 32, it is inserted into the lower recess 51.

[0017] As shown in Fig. 4, the plurality of wall portions 61 to 66 are arranged along a circle centered on the column portion 5. In the present embodiment, six wall portions 61 to 66 are provided and arranged along the circular periphery of the base 3. The plurality of wall portions 61 to 66 are provided in a long shape along the arrangement direction of the plurality of wall portions 61 to 62, that is, along the circumferential direction of the base 3. The side surfaces of the plurality of wall portions 61 to 66 on the column portion 5 side are provided on a curved surface that protrudes toward the column portion 5. The side surfaces of the plurality of wall portions 61 to 66 on the side away from the column portion 5 are provided in a shape along the periphery of the base 3.

[0018] In the present embodiment, the plurality of wall portions 61 to 66 are provided integrally with the base 3. However, similar to the column portion 5, the wall portions 61 to 66 and the base 3 may be provided as separate parts so that the wall portions 61 to 66 can be fitted into the base 3. Further, recesses 67 that fit into a lid 4 described later are provided on the upper surfaces of the plurality of wall portions 61 to 66. In the present embodiment, the recess 67 is provided in a rectangular shape in a top view.

[0019] The lid 4 is provided in a disk shape, protrudes from the center toward the base 3, and has a cylindrical central boss 41 that is fitted into the upper recess 52 of the column portion 5, and a rectangular columnar peripheral boss 42 that is arranged so as to surround the central boss 41 and is fitted into the recesses 67 provided in the wall portions 61 to 62.

[0020] Next, with reference to FIG. 2, the assembly procedure of the branch protection member 1 with a wire harness will be described. First, place the base 3 on the workbench, fit the mounting boss 31 provided on the base 3 into the lower recess 52 of the column portion 5, and attach the column portion 5 to the base 3. Next, arrange the branch portion WHd of the wire harness WH from above the base 3. Specifically, pass the trunk line Wt of the wire harness WH between the wall portion 61 and the wall portion 62. Thereby, when the lid 4 is attached to the base 3, the trunk line Wt of the wire harness WH is introduced from between the wall portion 61 and the wall portion 62 into the space between the base 3 and the lid 4. Further, after at least a part of the eight branch lines Wb branched from the trunk line Wt contacts the column portion 5 and is bent around the column portion 5 (that is, after being hooked on the column portion 5), it is passed between the other wall portion 62 and the wall portion 63, between the wall portion 63 and the wall portion 64, between the wall portion 64 and the wall portion 65, and between the wall portion 66 and the wall portion 61. Thereby, when the lid 4 is attached to the base 3, the branch line Wb of the wire harness WH is led out from between the other wall portions 62, 63, 64, 65, 66 and the wall portions 63, 64, 65, 66, 61 to the outside of the space between the base 3 and the lid 4.

[0021] After that, attach the lid 4 to the base 3. Specifically, fit the central boss 41 provided on the lid 4 into the upper recess 52 of the column portion 5, and fit the peripheral boss 42 into the recess 67 of the wall portions 61 to 66. Next, fit the mounting boss 7 provided on the vehicle body into the through hole 32 provided on the base 3, and attach the branch protection member 1 with a wire harness to the vehicle body.

[0022] According to the above-described embodiment, the trunk line Wt and the branch line Wb of the wire harness WH can be introduced into and led out from the inside and outside of the base 3 and the lid 4 from between the wall portions 61 to 66 arranged so as to surround the column portion 5 and between the wall portions 61 to 66. Thereby, it is possible to cope with branch portions WHd of all shapes, and the versatility is excellent. The branch line Wb of the wire harness WH is bent in contact with the column portion 5. Thereby, the displacement of the branch line Wb of the wire harness WH can be suppressed.

[0023] Further, according to the above-described embodiment, the plurality of wall portions 61 to 66 are provided to be long along the arrangement direction of the plurality of wall portions 61 to 66, and are provided on a curved surface whose side surface on the column portion 5 side protrudes toward the column portion 5. Thereby, even if the side surfaces of the wall portions 61 to 66 interfere with the branch wires Wb of the wire harness WH, damage to the branch wires Wb can be reduced.

[0024] Further, according to the above-described embodiment, the mounting boss 7 protruding from the vehicle body is inserted through the insertion hole 32 provided in the base 3 to the lower recess 51 provided in the column portion 5. Thereby, the length of the mounting boss 7 can be made sufficiently long, and the branch protection member 2 can be firmly attached to the vehicle body.

[0025] Further, according to the above-described embodiment, the base 3 and the column portion 5 are formed of separate parts, and the column portion 5 is provided by being fitted into the base 3. Thereby, it is possible to replace the column portion 5 with a size and shape that match the branch portion WHd of the wire harness WH, and further improve the versatility.

[0026] For example, when the number of branch wires Wb is small or thin and displacement is likely to occur, it is possible to replace the column portion 5 that can further suppress the displacement. As the column portion 3 that can further suppress the displacement, for example, those shown in FIGS. 6 and 7 can be considered.

[0027] Next, a branch protection member 2 showing another embodiment shown in FIG. 6 will be described. The differences between the branch protection member 2 shown in FIG. 1 and the branch protection member 2 shown in FIG. 6 are the shape of the base 3 and the shape of the column portion 5. The base 3 shown in FIG. 6 is not provided with the mounting boss 31, and a through hole 33 (first insertion hole) is provided at the center of the base 3. The column portion 5 is provided in a cylindrical shape, and one end is fitted into the through hole 33. Further, the column portion 5 is provided with a through hole 53 (second insertion hole) into which the mounting boss 7 provided on the vehicle body or the center boss 41 of the lid 4 is fitted. An uneven surface is provided on the outer surface of the column portion 5. This uneven surface increases the catching effect of the branch wire Wb, and further suppresses displacement.

[0028] Next, the branch protection member 2 shown in FIG. 7 will be described. The differences between the branch protection member 2 shown in FIG. 1 and the branch protection member 2 shown in FIG. 7 are the shape of the base 3 and the shape of the column portion 5. The base 3 shown in FIG. 7 is not provided with a mounting boss 31, and a through hole 34 (first insertion hole) is provided at the center of the base 3. Further, a concave portion 35 for fitting a plate portion 54 (to be described later) that is larger than the through hole 34 is provided at the center of the upper surface of the base 3.

[0029] The column portion 5 has, for example, a disk-shaped plate portion 54 (third plate portion) that is stacked on the base 3, a plurality of column portion main bodies 55 that protrude from the plate portion 54 toward the lid 4, and a mounting boss 56 that protrudes from the plate portion 54 toward the side opposite to the lid 4. One column portion main body 55 is provided at the center of the disk-shaped plate portion 54. Further, a plurality of column portion main bodies 55 are arranged so as to surround the central column portion main body 55. The mounting boss 56 is provided to protrude from the center of the disk-shaped plate portion 54, is fitted into the insertion hole 34 of the base 3, and the column portion 5 is attached to the base 3. A through hole 57 that penetrates from the lower end of the mounting boss 56 to the upper end of the central column portion main body 55 is provided in the column portion 5. The mounting boss 7 and the central boss 41 are fitted into this through hole 57.

[0030] As shown in FIG. 7, by providing a plurality of column portion main bodies 55, the catching effect of the branch line Wb is increased, and displacement can be further suppressed. Further, it can be easily replaced with the column portion 5 provided with a plurality of column portion main bodies 55.

[0031] Note that the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. can be made as appropriate. In addition, the material, shape, dimensions, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

[0032] For example, in the above-described embodiment, the plurality of wall portions 61 to 66 are arranged side by side along the circular periphery of the base 3, but the present invention is not limited to this. The wall portions 61 to 66 may be provided so as to surround the column portion 5, and may be erected from the inside of the edge portion of the base 3.

[0033] Also, in the above-described embodiment, the column portion 5 was erected from the center of the area surrounded by the plurality of wall portions 61 to 66, but it is not limited to this. The column portion 5 may not be erected from the center as long as it is within the area surrounded by the plurality of wall portions 61 to 66.
