Description

The present invention relates to a holder and a wire harness.

As an example of a conventional technology related to a wire harness holder, Patent Document 1 discloses a protector that includes a main body having an insertion space inside through which a wiring material is inserted along the axial direction, and a lid that closes the upper open end of the insertion space in the main body.

JP 2009-50106 A

However, in the protector described in the above-mentioned Patent Document 1, for example, multiple insertion spaces are provided inside the main body in a line crossing the axial direction, so there is a risk that the main body will become relatively large.

The present invention was made in consideration of the above circumstances, and aims to provide a holder and a wire harness that can prevent the size from increasing.

To achieve the above object, the holder according to the present invention has a bottom wall and a pair of side walls intersecting the bottom wall, and includes a main body having an insertion space inside the pair of side walls through which a first wiring material is inserted along the axial direction, a cross section intersecting the axial direction formed in a U-shape, a wiring material holding part provided on the outer surface of at least one of the pair of side walls and having a holding space recessed from the outer surface toward the insertion space and holding a second wiring material that is wired along the axial direction, and a fixing member that fixes the first wiring material to the insertion space and fixes the second wiring material to the holding space.

The holder and wire harness according to the present invention can fix a first wiring material in an insertion space provided on the inside of a pair of side walls of the main body, while fixing a second wiring material in a holding space provided on the outer surface of at least one of the side walls constituting the wiring material holding portion. Therefore, the holder and wire harness can be configured to suppress an increase in width in a direction intersecting with the axial direction of the main body. As a result, the holder and wire harness have the effect of suppressing an increase in size.

[Embodiment]
Fig. 1 is a perspective view of a wire harness WH to which a holder 1 according to an embodiment is applied in a first usage mode. The holder 1 of the present embodiment shown in Fig. 1 is incorporated into a wire harness WH to be routed in a vehicle such as an automobile, and is covered with a conductive wiring material W to hold the wiring material W. Here, the wire harness WH is, for example, a collective part in which a plurality of wiring materials W used for power supply and signal communication are bundled together to connect each device mounted on the vehicle, and the plurality of wiring materials W are connected to each device by a connector or the like.

The wire harness WH of this embodiment includes a first wiring material W1 and a second wiring material W2 as wiring materials W, and also includes a third wiring material W3 selectively depending on the specifications of the vehicle to which it is applied. In other words, in a first usage mode depending on the specifications of the vehicle to which it is applied, the wire harness WH of this embodiment includes a first wiring material W1, a second wiring material W2, and a third wiring material W3, a plurality of corrugated tubes C as an exterior material into which each wiring material W is inserted, and a holder 1 that holds the plurality of corrugated tubes C (wiring materials W). In this case, the holder 1 is provided on the first wiring material W1, the second wiring material W2, and the third wiring material W3, and holds the first wiring material W1, the second wiring material W2, and the third wiring material W3.

On the other hand, in the second usage mode (see FIG. 4) according to the vehicle specifications to which the wire harness WH of this embodiment is applied, the wire harness WH includes a first wiring material W1 and a second wiring material W2, a plurality of corrugated tubes C as exterior materials into which the wiring materials W are inserted, and a holder 1 that holds the plurality of corrugated tubes C (wiring materials W). In this case, the holder 1 is provided on the first wiring material W1 and the second wiring material W2, and holds the first wiring material W1 and the second wiring material W2.

In addition, the wire harness WH may further include a protector through which the first wiring material W1, the second wiring material W2, the third wiring material W3, etc. are inserted to protect each of the wiring materials W, a grommet, a fastener, a connector, etc. In this case, the holder 1 may be applied to, for example, the insertion port portion of the protector, or may be provided separately without relation to the protector, etc.

In the following description, the first direction, the second direction, and the third direction intersect with each other, and the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z are approximately perpendicular to each other. The axial direction X typically corresponds to the extension direction of the corrugated tube C held by the holder 1, the insertion direction of the wiring material W into the holder 1, the extension direction of the wiring material W inserted into the holder 1, etc. The width direction Y and the height direction Z correspond to intersecting directions that intersect with the axial direction X. In addition, unless otherwise specified, each direction used in the following description will be described as a direction in a state in which the wiring material W is assembled to the holder 1.

The wiring material W is composed of, for example, a metal rod, an electric wire, a bundle of electric wires, etc. The metal rod is a rod-shaped member having conductivity covered on the outside with an insulating coating. The electric wire is a conductor (core wire) made of multiple conductive metal strands covered on the outside with an insulating coating. The bundle of electric wires is a bundle of such electric wires. The wiring material W of this embodiment includes a first wiring material W1, a second wiring material W2, and a third wiring material W3. Here, the first wiring material W1, the second wiring material W2, and the third wiring material W3 are described as being formed into a substantially circular cross-sectional shape and having substantially the same outer diameter and shape, but are not limited to this.

The corrugated tube C is formed into a flexible cylindrical (tubular) shape using an insulating resin material. Multiple corrugated tubes C (three in this example) are provided, and the first wiring material W1, the second wiring material W2, and the third wiring material W3 are inserted into each of them to protect the first wiring material W1, the second wiring material W2, and the third wiring material W3. The corrugated tube C has a ring-shaped annular recess Ca formed on the outer circumferential surface C1, and the multiple annular recesses Ca are provided along the axial direction X, forming a bellows shape.

The holder 1 is made of an insulating resin material and is formed into a U-shape that is open on one side in the height direction Z as a whole. The first wiring material W1, the second wiring material W2, and the third wiring material W3 are arranged in the holder 1, and the holder 1 holds the first wiring material W1, the second wiring material W2, and the third wiring material W3 while regulating the wiring path of each wiring material W. In this configuration, the holder 1 of this embodiment is provided with an insertion space 13 on the inside of the U-shape through which the first wiring material W1 is inserted, while a holding space 21 is provided on the outside of the U-shape in which the second wiring material W2 and the third wiring material W3 are held. As a result, the holder 1 of this embodiment is configured to suppress the widening in the width direction Y that intersects with the axial direction X. The configuration of the holder 1 will be described in detail below with reference to each figure.

Figure 2 is a perspective view of the holder 1 according to the embodiment. As shown in Figure 2, the holder 1 includes, for example, a main body 10, a wiring material holding portion 20, and a tape 30 (see Figure 3) described below. The main body 10 is a portion through which the first wiring material W1 described above is inserted along the axial direction X and which holds the first wiring material W1.

The main body 10 has a bottom wall 11 and a pair of side walls 12 that intersect with the bottom wall 11, and has a U-shaped cross section that intersects with the axial direction X. The bottom wall 11 and the pair of side walls 12 are structures for partitioning the insertion space 13 described above as the internal space of the main body 10. The insertion space 13 is a space into which the first wiring material W1 is inserted and routed. The bottom wall 11 is formed in a plate shape and extends along the axial direction X. The pair of side walls 12 are formed to protrude along the height direction Z from both ends of the bottom wall 11 in the width direction Y, and extend along the axial direction X.

The main body 10 is formed integrally with a bottom wall 11 and a pair of side walls 12, and the internal space surrounded by the bottom wall 11 and the pair of side walls 12 constitutes the insertion space 13 described above. The inner surface 13a of the insertion space 13 is formed in an arc shape extending along the outer peripheral surface C1 of the first wiring material W1 (corrugated tube C) described above. The main body 10 is made of a synthetic resin material such as polypropylene or nylon.

The main body 10 is provided with an elastic support portion 14 that protrudes from the inner surface 13a of the insertion space 13. The elastic support portion 14 is a portion that elastically supports the first wiring material W1 (corrugated tube C). In this embodiment, the main body 10 is provided with a pair of elastic support portions 14 spaced apart from each other in the width direction Y.

The pair of elastic support parts 14 are formed in a curved shape that is convex from the inner surface 13a of the insertion space part 13 toward the first wiring material W1 side, and extend along the axial direction X. The lower end of the elastic support part 14 is connected to the bottom wall 11 of the main body part 10, and the upper end is connected to the side wall 12 of the main body part 10. In this configuration, in this embodiment, the first wiring material W1 (corrugated tube C) is elastically clamped between the pair of elastic support parts 14, thereby increasing the holding force of the first wiring material W1. The elastic support part 14 is also called a stabilizer, etc.

The wiring material holding portion 20 is a portion in which the second wiring material W2 and the third wiring material W3 are arranged along the axial direction X, and holds the second wiring material W2 and the third wiring material W3. In this embodiment, the wiring material holding portion 20 is provided on each outer surface 12a of the pair of side walls 12.

The wiring material holding portion 20 has a holding space 21 recessed from the outer surface 12a of the side wall 12 toward the insertion space 13. The holding space 21 is a space in which the second wiring material W2 and the third wiring material W3 are routed and held, and is recessed in an arc shape along the outer peripheral surface C1 of the second wiring material W2 and the third wiring material W3 (corrugated tube C).

The wiring material holding portion 20 is provided with a protrusion 22 protruding from the inner surface 21a of the holding space portion 21. The protrusion 22 is a portion that engages or fits with the annular recess Ca formed on the outer peripheral surface C1 of the corrugated tube C described above. In this embodiment, the protrusion 22 is provided on each of the pair of wiring material holding portions 20 and is positioned in the center of the wiring material holding portion 20 in the axial direction X.

The convex portion 22 is formed, for example, by curving in an arc along the inner surface 21a of the holding space portion 21 or the bottom of the annular recess Ca (see FIG. 3). In this configuration, in this embodiment, the second wiring material W2 and the third wiring material W3 to which the corrugated tube C is attached can be temporarily fixed to the wiring material holding portion 20 by the engagement between the convex portion 22 and the annular recess Ca. This makes it possible to limit the movement of the second wiring material W2 and the third wiring material W3 in the axial direction X relative to the wiring material holding portion 20 and the movement outward (in the direction of removal) in the width direction Y.

In the holder 1 configured as described above, the first wiring material W1 is inserted from one opening end to the other opening end along the axial direction X into the insertion space 13 formed by the bottom wall 11 and the pair of side walls 12 in the main body 10. In addition, the second wiring material W2 and the third wiring material W3 are arranged in the retention space 21 provided on the outer surface 12a of the pair of side walls 12 in the wiring material holding part 20 from one opening end to the other opening end along the axial direction X. In the holder 1 of this embodiment, the first wiring material W1, the second wiring material W2, and the third wiring material W3 are fixed by a tape 30 (see FIG. 3) described later while being arranged in the insertion space 13 and the retention space 21.

Figure 3 is a cross-sectional view of the wire harness WH to which the holder 1 according to the embodiment is applied in a first usage form. As shown in Figure 3, the tape 30 is a member for fixing the first wiring material W1 to the insertion space portion 13 and fixing the second wiring material W2 and the third wiring material W3 to the holding space portion 21. In the first usage form shown in Figure 3, the tape 30 is formed in a cylindrical shape surrounding the first wiring material W1, the second wiring material W2, and the third wiring material W3. That is, one end side of the tape 30 in the width direction Y is fixed along the outer peripheral surface C1 of the second wiring material W2 (corrugated tube C), the other end side of the tape 30 in the width direction Y is fixed along the outer peripheral surface C1 of the third wiring material W3 (corrugated tube C), and the center side of the tape 30 in the width direction Y is fixed to the outer peripheral surface C1 of the first wiring material W1 (corrugated tube C). The tape 30 is an example of a fixing material.

For example, the tape 30 fixes the first wiring material W1 to the insertion space 13 while pressing it against the pair of elastic support portions 14, and fixes the second wiring material W2 and the third wiring material W3 to the retention space 21 while pressing them against the protrusion 22. In other words, the tape 30 fixes the first wiring material W1 in a state where it does not float up from the insertion space 13 to one side in the height direction Z, and fixes the second wiring material W2 and the third wiring material W3 in a state where they do not float up from the retention space 21 to the outside in the width direction Y (the removal direction).

For convenience, FIG. 3 shows the shape of the pair of elastic support parts 14 in a free state, but in reality, they elastically deform along the outer peripheral surface C1 of the first wiring material W1 (corrugated tube C) inserted into the insertion space 13. That is, when the first wiring material W1 is inserted into the insertion space 13, the pair of elastic support parts 14 are curved in a convex state toward the opposite side to the first wiring material W1, in other words, in a U-shape that opens toward the first wiring material W1 side. The elastic support parts 14 have the function of absorbing errors, for example, between the first wiring material W1 and the corrugated tube C, which have different diameters, by elastically deforming between the insertion space 13 and the first wiring material W1 (corrugated tube C).

Figure 4 is a cross-sectional view of the wire harness WH to which the holder 1 according to the embodiment is applied in a second usage form. In the second usage form shown in Figure 4, the tape 30 is formed in a cylindrical shape surrounding the first wiring material W1 and the second wiring material W2. That is, one end side of the tape 30 in the width direction Y is fixed along the outer surface C1 of the second wiring material W2 (corrugated tube C), the other end side of the tape 30 in the width direction Y is fixed along the outer surface 12a of the side wall 12 of the holder 1, and the center side of the tape 30 in the width direction Y is fixed to the outer surface C1 of the first wiring material W1 (corrugated tube C).

As in the first usage form, the tape 30, for example, fixes the first wiring material W1 to the insertion space 13 while pressing it against the pair of elastic support portions 14, and fixes the second wiring material W2 to the retention space 21 while pressing it against the protrusion 22. In this way, the protector of this embodiment is configured to allow parts to be shared between the first usage form having the first wiring material W1, the second wiring material W2, and the third wiring material W3, and the second usage form having only the first wiring material W1 and the second wiring material W2.

As described above, the holder 1 and the wire harness WH of this embodiment have a bottom wall 11 and a pair of side walls 12 intersecting the bottom wall 11, and a main body 10 having a U-shaped cross section intersecting the axial direction X, with an insertion space 13 provided inside the pair of side walls 12 through which the first wiring material W1 is inserted along the axial direction X, a wiring material holding part 20 provided on the outer surface 12a of at least one of the pair of side walls 12 and provided with a holding space 21 recessed from the outer surface 12a toward the insertion space 13 side and holding the second wiring material W2 that is routed along the axial direction X, and a tape 30 (fixing material) that fixes the first wiring material W1 to the insertion space 13 and fixes the second wiring material W2 to the holding space 21.

With this configuration, the holder 1 and the wire harness WH can fix the first wiring material W1 in the insertion space 13 provided on the inside of a pair of side walls 12 in the main body 10, while fixing the second wiring material W2 in the holding space 21 provided on the outer surface 12a of at least one of the side walls 12 that constitute the wiring material holding portion 20. Therefore, the holder 1 and the wire harness WH can be configured to suppress the increase in width of the main body 10 in the width direction Y, compared to a conventional structure in which multiple insertion spaces 13 are provided inside the main body 10 in a line in the width direction Y that intersects with the axial direction X. As a result, the holder 1 and the wire harness WH can be prevented from becoming large and can be made lighter.

The fixing material is not limited to the tape 30 described above, but may be, for example, a cable tie that fixes the first wiring material W1 to the insertion space 13 and fixes the second wiring material W2 to the retention space 21.

In addition, in the holder 1 and wire harness WH of this embodiment, the wiring material holding portion 20 is provided on each of the pair of side walls 12. With this configuration, the holder 1 and wire harness WH can share parts between a first usage form having the first wiring material W1, the second wiring material W2, and the third wiring material W3, and a second usage form having only the first wiring material W1 and the second wiring material W2. As a result, the holder 1 and wire harness WH can reduce the effort and cost required for manufacturing the holder 1 and wire harness WH.

In addition, in the holder 1 and wire harness WH of this embodiment, the main body 10 is provided with an elastic support portion 14 that protrudes from the inner surface 13a of the insertion space portion 13 and elastically supports the first wiring material W1. With this configuration, the holder 1 and wire harness WH can absorb errors in the first wiring material W1 with different diameters, for example, by elastic deformation of the elastic support portion 14, and can therefore be configured to be capable of fixing first wiring materials W1 of multiple specifications with different diameters.

The elastic support portion 14 is not limited to the pair of shapes described above, and may be configured, for example, to be provided in a state in which it protrudes from one of the pair of side walls 12 of the main body portion 10, and the first wiring material W1 may be configured to be elastically clamped between the one elastic support portion 14 and the other side wall 12. Also, for example, it may be configured so that an elastically deformable intervening member made of rubber, resin, or the like is provided between the main body portion 10 and the first wiring material W1.

In addition, in the holder 1 and the wire harness WH of this embodiment, the second wiring material W2 is fitted with a corrugated tube C provided with an annular recess Ca, and the wiring material holding portion 20 is provided with a protrusion 22 that protrudes from the inner surface 21a of the holding space portion 21 and engages with the annular recess Ca. With this configuration, the holder 1 and the wire harness WH can temporarily fix the second wiring material W2 to which the corrugated tube C is attached to the wiring material holding portion 20 by engaging the annular recess Ca with the protrusion 22, and thus can limit the movement of the second wiring material W2 in the axial direction X relative to the wiring material holding portion 20 and the movement outward (in the width direction Y). As a result, the holder 1 and the wire harness WH can make it easier or smoother to fix the first wiring material W1 and the second wiring material W2 using, for example, the tape 30.

Although the above is an example of an embodiment of the present invention, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications of each configuration, shape, etc. (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
