JP 2011-234474 A

By the way, in the case of the above conventional protector, since a lid member is required as a component part in addition to the main body member, there is a situation that the number of parts is increased and management is troublesome. In view of this, it is also possible to omit the lid member and wind the tape around the body member and the wire harness from the outside with the wire harness housed in the housing groove of the body member, and fix the wire harness around the body member by tape winding. It is. However, if the shape of the protector becomes complicated due to reasons such as vehicle layout and a step in the height direction is formed at the bottom, the wire harness will rise in the height direction, making it difficult to perform tape winding work. There is.

The present invention has been completed based on the above situation, and an object of the present invention is to provide a protector capable of maintaining the holding state of electric wires without increasing the number of parts.

The protector according to the present invention has a form extending in a wiring direction of the electric wires, and has a mounting surface on which the electric wires are mounted, and an insertion in which the electric wires are inserted on the side facing the mounting surface. A protector comprising a protector main body opened as a mouth, wherein the protector main body rises from the placement surface to the insertion port side, and is arranged in a plurality in a direction intersecting a wiring direction of the electric wires, and the alignment direction Between the adjacent ones, a plurality of side walls each having a substantially U-shaped holding groove for receiving the electric wires inserted into the insertion port, and a plurality of the side walls from the inner surfaces of the side walls in the holding grooves. It is characterized in that it has a protruding shape and has a protrusion that bends the electric wires so that the electric wires meander and are arranged when viewed from the insertion port side.

Since the electric wires meander and are bent and held by the protrusions, the electric wires can be prevented from floating from the protector even if the lid member or the like is omitted. Therefore, the holding state of the electric wires can be maintained without increasing the number of parts.

It is a perspective view of the protector of Example 1 of the present invention. It is the perspective view which looked at the protector from another angle. It is a principal part top view of the holding groove of a protector. FIG. 3 is a sectional view taken along line AA in FIG. 2. It is a perspective view showing the use condition of a protector.

The present invention may have the following aspects.
The protrusions are alternately arranged on the side wall portions adjacent in the arrangement direction when viewed from the insertion port side. Thereby, electric wires can be smoothly meandered.

The protector body has a substrate part having the mounting surface described above and a pair of side plate parts rising from both ends in the width direction of the substrate part, and the side plates are the pair of side plate parts and the pair of side plate parts. And at least one partition plate rising from an intermediate position in the width direction of the substrate portion. Thereby, a plurality of electric wires can be arranged in the protector body in parallel in the width direction and meandered.

The holding groove is arranged only at a midway position in the length direction of the protector body. Thereby, it can arrange | position only to the location which requires a holding groove, and can further simplify the structure of a protector.

The protector main body has a flat portion having the mounting surface as a flat surface, and the holding groove is arranged in the flat portion. If it carries out like this, since it can control reliably that electric wires float from a holding groove, the holding reliability by each protrusion of a holding groove can be improved.

The protector main body has a step portion which is inclined in the height direction adjacent to the plane portion and intersecting the plane portion. If such a stepped portion exists, the electric wires are likely to be lifted, so that the merit of suppressing the lifting of the electric wires in the flat portion is great.

In the protector body, an attachment portion attached to the member to be attached is formed so as to protrude in a direction intersecting the length direction, and the attachment portion is disposed adjacent to the holding groove. Although there is a situation that it is difficult to wind the tape when such a mounting portion exists, according to the present invention, since the lifting of the electric wires can be suppressed by the protrusions of the holding grooves, it is not necessary to wind the tape around the mounting portion. It can be.

The electric wires are individually accommodated in the holding grooves, and among the protrusions, the terminal protrusions positioned at the drawing end portions of the electric wires in the holding grooves are all Of the side wall portions adjacent in the arrangement direction, the side wall portions are arranged on the same side wall portion in the arrangement direction. According to this, the electric wires pulled out from each holding groove can be synchronized and smoothly bent to the side wall portion where the terminal protrusion is located.

Each of the protrusions has a rib shape extending in the rising direction of the side wall portion. According to this, even if the electric wires are loosely moved in the depth direction of the holding groove, each protrusion can be reliably engaged with the electric wires.

Each projection has an arc-shaped cross section. According to this, it can prevent that the outer peripheral surface of electric wires is damaged by each protrusion.

<Example 1>
A first embodiment of the present invention will be described with reference to FIGS. The protector according to the first embodiment is made of a synthetic resin, and includes a protector body 10 that extends along the direction in which the cable 60 is routed.

As shown in FIGS. 1 and 2, the protector body 10 has a shallow saddle shape, and includes a strip-like substrate portion 11 and a pair of side plate portions 12 that rise from both ends in the width direction of the substrate portion 11. Yes. The upper surface of the protector body 10 is opened as an insertion port 13 into which each cable 60 as an electric wire is inserted. The upper surface of the board portion 11 is a placement surface 26 on which a plurality of cables 60 are placed in parallel in the width direction, and each cable 60 is arranged so as to fit between the side plate portions 12. Yes.

The protector body 10 has a flat portion 14 in the middle of the length direction (the direction in which the cable 60 is routed), and a step portion at a position adjacent to the flat portion 14 on both sides in the length direction across the flat portion 14. 15. The flat surface portion 14 is configured by the substrate portion 11 that makes the placement surface 26 of the cable 60 a flat surface, and the step portion 15 inclines the placement surface 26 of the cable 60 in the height direction with respect to the flat surface. A substrate unit 11 is used.

A flat cover 16 is attached to one end of the protector body 10 in the length direction. The cover 16 is integrally connected to a rising end of one of the side plate portions 12 through a flexible hinge 17 so that the insertion port 13 of the protector body 10 can be opened and closed.

Further, the protector body 10 is formed with a plurality of attachment portions 18 at intervals in the length direction. The mounting portion 18 is configured to protrude from the one side plate portion 12 in the width direction (the direction intersecting the cable 60 wiring direction and the arrangement direction of the side plate portions 12 and the partition plate portions 22 described later). The side plate portion 12 is integrally connected. The mounting portion 18 having the largest protruding dimension among the mounting portions 18 is arranged in parallel adjacent to the flat surface portion 14 in the width direction.

A mounting hole 19 is provided in the mounting portion 18, and as shown in FIG. 5, the protector is mounted and fixed to a mounted member 80 such as a vehicle floor panel via a mounting tool 20 inserted into the mounting hole 19. It has come to be. In the illustrated case, the protector is turned upside down and attached so that the insertion port 13 faces the attached member 80. Thereby, each cable 60 is arrange | positioned between the protector main body 10 and the to-be-attached member 80, and is protected from the outside by the protector main body 10. FIG.

Further, as shown in FIG. 4, the protector body 10 is formed with a holding groove 21 having a U-shaped cross section that can accommodate the cable 60, specifically, a substantially square U-shaped cross section. A plurality of the holding grooves 21 are arranged in parallel in the width direction in the plane portion 14, and are arranged at two positions spaced apart in the length direction of the protector body 10 as shown in FIGS. 1 and 2. Among these, each holding groove 21 disposed on the flat surface portion 14 on one end side in the length direction is disposed adjacent to the mounting portion 18 in the width direction. Each cable 60 is individually accommodated in each holding groove 21.

Specifically, as shown in FIG. 4, the holding groove 21 is partitioned by the substrate portion 11, the side plate portions 12, and a plurality of partition plate portions 22 disposed between the side plate portions 12. Each partition plate portion 22 is configured to rise substantially vertically upward from the substrate portion 11, and is arranged to be thinner than the side plate portion 12 and substantially parallel to the side plate portion 12. The gap between the partition plate portions 22 at both ends in the width direction and the side plate portions 12 is made larger than the gap between the adjacent partition plate portions 22, that is, the groove width of the holding grooves 21 at both ends in the width direction is between them. The groove width of the holding groove 21 is larger.

As shown in FIGS. 3 and 4, a plurality of protrusions 23 are provided on the side wall (inner surface) of each partition plate portion 22 and both side plate portions 12 (hereinafter referred to as side wall portions 12, 22) that divide the holding groove 21. It has been. Each projection 23 has a substantially arc shape in cross section, and has a rib-like shape extending over substantially the entire length in the height direction of the

side wall portions

12, 22, in other words, in the depth direction of the holding groove 21. The distance between the protruding end of each protrusion 23 and the inner surfaces of the

side wall portions

12 and 22 facing each other is substantially the same as the diameter of the cable 60 inserted into the corresponding holding groove 21.

Further, as shown in FIG. 3, each projection 23 is alternately arranged along the length direction of the protector body 10 on each of the

side wall portions

12 and 22 adjacent in the width direction when viewed from the insertion port 13 side. Arranged in a staggered pattern. Furthermore, each protrusion 23 is arrange | positioned in the same position regarding the length direction of the protector main body 10 in the

side wall parts

12 and 22 located in the same side in the width direction among the

side wall parts

12 and 22 adjacent in the width direction. . For this reason, among the protrusions 23, the terminal protrusions 23A located at the lead-out ends of the cable 60 are arranged coaxially in the width direction on the

side wall parts

12 and 22 located on the same side in the width direction. It has become so.

Now, when the cable 60 is inserted into each holding groove 21 from the insertion port 13, each inserted cable 60 bends in the width direction while meandering between the projections 23 of each holding groove 21 as shown in FIG. Are arranged. In this case, each cable 60 is urged by a force to return to the original straight traveling state, and is pressed tightly against each protrusion 23 from the width direction so as to be held between the protrusions 23 in a retaining state. It has become. For this reason, even if there is a situation that the step portion 15 is formed in the protector main body 10, the state in which each cable 60 is placed on the substrate portion 11 without being lifted in the flat portion 14 is reliably maintained. It has become.

Further, each cable 60 shown in the figure is bent toward the

side wall portions

12 and 22 where the end projections 23 are located. At this time, the end projections 23A arranged in parallel in the width direction come into contact with the bent portion of the cable 60, so that the bending operation of each cable 60 is synchronized and smoothly guided.

Thereafter, a tape (not shown) is wound around the protector body 10 and each cable 60 from the outside. Thereby, each cable 60 is firmly fixed to the protector body 10. While the tape winding operation is performed, the protrusions 23 of the holding grooves 21 prevent the cables 60 from being lifted, so that the smoothness and quickness of the operation can be ensured. In addition, since the holding state of the cable 60 is maintained by the projections 23 of the holding grooves 21, it is possible to eliminate the need for tape winding around the locations where the holding grooves 21 are formed.

As described above, according to the first embodiment, the protrusions 23 are alternately arranged in the zigzag along the length direction on the

side wall portions

12 and 22 adjacent in the width direction, so that the cable 60 is Since the protrusions 23 meander and bend and hold, the cable 60 can be prevented from being lifted from the protector without the cover member for closing the insertion port 13 of the protector body 10. Therefore, the holding state of the cable 60 can be maintained without increasing the number of parts.

Further, since the holding groove 21 is disposed only in a part of the protector body 10 in the length direction and is disposed only in a required portion, the structure of the protector is further simplified.

Moreover, since the protector body 10 has the flat portion 14 that makes the mounting surface 26 of each cable 60 a flat surface, and each holding groove 21 is disposed in the flat portion 14, each cable 60 is connected to each holding groove 21. It is possible to reliably control the floating. In this case, since the protector body 10 has the step portion 15 that is adjacent to the plane portion 14 and intersects with the plane portion 14, there is a great merit that the lifting of the cables 60 can be suppressed in the plane portion 14.

Furthermore, since the protector body 10 has an attachment portion 18 attached to the attached member 80, and the attachment portion 18 protrudes in the width direction and is disposed adjacent to the holding groove 21, it is difficult to wind the tape at the attachment portion 18. However, according to the first embodiment, since the cable 60 is prevented from being lifted by the protrusions 23 of the holding groove 21 in the flat surface portion 14, it is possible to eliminate the need for tape winding around the attachment portion 18. . As a result, the work burden of winding the tape is reduced and the cost can be reduced.

The present invention is not limited to the first embodiment, and may be, for example, as follows.
(1) The holding groove may accommodate an electric wire that is generally smaller in diameter than the cable as electric wires instead of the cable.
(2) A plurality of electric wires may be accommodated in one holding groove.
(3) The protector may have only one holding groove.
(4) The holding groove may extend over the entire length of the protector.
(5) If the cable or the electric wire is firmly fixed to the holding groove by each protrusion, the tape winding operation can be made unnecessary.
