Description

  The present invention relates to a clip for a wire harness. Specifically, the clip is fixed to a component such as a phosphorus hose mounted in an instrument panel of an automobile, and the wire harness is routed along the component or provided on the wire harness. The splice part is fixed.

  Conventionally, a wire harness routed in an instrument panel of an automobile is routed along a phosphorus hose pivoted in the vehicle width direction in the instrument panel.

For example, Japanese Patent Laying-Open No. 2002-220011 (Patent Document 1) provides a wiring structure for a wire harness shown in FIG. In the structure, a groove portion 1a extending in the length direction is formed in the reinforcing member 1 in the instrument panel, and the protector 2 sheathed on the wire harness W / H is accommodated in the groove portion 1a. The clip 2 a is inserted and locked in the locking hole 1 b of the reinforcing member 1.
However, in the case of the above structure, there is a problem in that the specially shaped reinforcing member 1 provided with the groove portion 1a must be provided, resulting in high costs and poor versatility, and the strength of the reinforcing member 1 is reduced.

Further, in Japanese Patent Application Laid-Open No. 2002-176716 (Patent Document 2), a protector 3 having a crescent-shaped cross section shown in FIG. 15 is provided, and a clip 3a provided on the protector 3 is provided with a locking hole provided on the reinforcing member 4. The protector 3 is fixed to the reinforcing member 4 in a state where the protector 3 is aligned with the outer peripheral surface of the reinforcing member 4.
However, in the case of the protector 3 provided in Patent Document 2, the protector 3 externally mounted on the wire harness W / H is merely placed along the reinforcing member 4, so that a large number of locking holes 4 a are used for fixing. Has to be provided on the reinforcing member 4, and there are problems that the manufacturing process of the reinforcing member 4 increases and the strength of the reinforcing member 4 decreases.
Moreover, since the protector provided by the said patent document 1 and the patent document 2 must be attached in the state which cannot see the clip provided in the protector, and the latching hole provided in the reinforcement member, it can attach to the reinforcement member of a protector. There is a problem that makes the work difficult. Furthermore, since the clip is provided on the protector by the clip provided on the protector, it is necessary to cut off the clip part with a tool or pull the wire harness with a considerable force in the dismantling work at the time of disposal of the automobile. Therefore, there is a problem that the wire harness cannot be easily removed.

On the other hand, the present applicant provides a protector 5 that does not require a locking structure on the reinforcing member side in Japanese Patent Application Laid-Open No. 2000-324663 (Patent Document 3). As shown in FIG. 16, the protector 5 includes an arcuate locking spring piece 5a. The protector 5 is fixed to the reinforcing member 6 by sandwiching the reinforcing member 6 from above and below with the locking spring piece 5a. ing.
With the protector 5 provided in Patent Document 3, there is no need to provide a locking structure such as a locking hole in the reinforcing member 6, the cost of the reinforcing member 6 can be reduced and the strength can be increased, and Versatility can be improved.
However, since the wire harness W / H to be inserted into the protector 5 is concentrated in one place, the wire harness W / H protrudes from the reinforcing member 6, and there is room for improvement in this respect.

Japanese Patent Laid-Open No. 2002-220011 JP 2002-176716 A JP 2000-324663 A

  The present invention has been made in view of the above-mentioned problems, enables the wire harness to be fixed without providing a locking structure to a component mounted on an automobile such as a phosphorus hose, and facilitates the fixing work, and It is an object of the present invention to prevent the wire harness attached to the component from locally protruding from the component and to enable the wiring harness to be routed even in a narrow space.

In order to solve the above-mentioned problem, the present invention firstly is a clip for fixing a wire harness to another component mounted on an automobile,
An inner peripheral wall that is curved into a C-shaped cross section and is provided with a bent portion at one end of an arc;
A C-shaped cross-section that is folded back from the other end of the arc of the inner peripheral wall to the outer periphery via a first hinge portion and surrounds the inner peripheral wall with a space therebetween, and a second hinge between the first hinge portion and the tip An outer peripheral wall provided with a portion;
A lock portion provided between a tip of the outer peripheral wall and an outer surface provided with a required dimension from one end provided with a leading bent portion of the inner peripheral wall;
Protruding from the outer surface of the inner peripheral wall and the inner surface of the outer peripheral wall facing each other with the space therebetween, and comprising partition walls to be locked together,
A clip for a wire harness, characterized in that the wire harness clip is configured to be externally fitted to and attached to the other component in a state in which the wire group constituting the wire harness is distributed and passed through a space between the inner peripheral wall and the outer peripheral wall. providing.

According to the first clip for the wire harness of the present invention, the wire harness electric wire group is dispersed and passed through the space sandwiched between the inner peripheral wall and the outer peripheral wall having a C-shaped cross section. Since the fitting is fixed, the wire harness fixed to the component does not protrude greatly from the component. Thereby, even if there is no sufficient space around the component, the wire harness can be efficiently routed in a narrow space.
Further, since the clip is externally fixed to the component, it is not necessary to provide a locking portion on the clip and fix the clip to the component. Therefore, it is not necessary to provide a locking structure such as a locking hole in the component, and the work can be facilitated even if it is attached at a position where it cannot be seen, and the clip can be easily removed when the automobile is disassembled. it can. Further, when the component is a reinforcing member such as a phosphorus hose, there is no need to provide a locking structure, so that the strength does not decrease.
Furthermore, since the outer peripheral wall is not provided on the outer surface side of the guiding bending portion provided at one end of the inner peripheral wall, and the guiding bending portion is easily bent, when the clip is externally fixed to the component, The guiding bent portion is sufficiently bent, and an opening portion into which the part of the C-shaped clip is inserted is greatly expanded, so that the clip can be easily attached to the part.
Furthermore, because the partition wall partitioning the space between the inner peripheral wall and the outer peripheral wall protrudes from the outer surface of the inner peripheral wall and the inner surface of the outer peripheral wall and is locked together, the clip is difficult to deform in the middle in the circumferential direction, And the electric wire which passed through the said space is not bitten by the partition.

The number of second hinge portions provided between the first hinge portion and the tip of the outer peripheral wall of the clip is not limited to one, and a plurality of second hinge portions may be provided.
Moreover, it is preferable that the position where the second hinge portion is provided is slightly on the tip side of the partition wall portion protruding from the inner surface of the outer peripheral wall.
Further, when a plurality of partition walls are provided, a second hinge portion is provided on the distal end side of the outer peripheral wall for each partition wall, and locking of the partition walls and locking of the lock parts are performed individually rather than collectively. It is preferable that it can be performed. Thereby, the insertion of the electric wire group into the space between the outer peripheral wall and the inner peripheral wall and the locking of the partition wall portion can be performed alternately, and the insertion operation of the electric wire group into the C-shaped clip can be facilitated. it can.

It is preferable that the inner peripheral wall of the clip has an arc shape exceeding 180 degrees and not more than 300 degrees.
Moreover, it is preferable that the width direction of the clip which is the penetration direction of a wire harness is 25-35 mm.
This is because if the width of the clip is smaller than 25 mm, the holding force when fitted to the component is weakened and the clip cannot be attached to the component in a stable state. This is because it becomes difficult and the fitting work becomes complicated.
Furthermore, when a plurality of clips are attached to the component at intervals, the wire harness can be routed along the component between the clips.

In addition, the present invention is secondly a clip for fixing a wire harness to another component mounted on an automobile,
An inner peripheral wall that is curved into a C-shaped cross section and is provided with a bent portion at one end of an arc;

A partition wall partitioning a space sandwiched between the inner peripheral wall and the outer peripheral wall;
A bottom wall portion sandwiched between the inner peripheral wall and the outer peripheral wall and having a bottomed cylindrical shape by closing part or all of the plurality of chambers partitioned by the partition wall;
A terminal splice part in which the ends of a plurality of electric wires are welded or pressure-bonded is inserted into the chamber having a bottomed cylindrical shape, and a water-stopping agent is filled in the chamber, and the terminal splice part is embedded in the water-stopper. In this state, a wire harness clip is provided which is configured to be externally fitted and attached to the other component.

According to the second clip for a wire harness of the present invention, the terminal splice portion can be easily fixed to the outer surface of the component in a narrow space around the component.
In addition, like the first wire harness clip, there is no need to provide a locking structure on the component side.
Further, like the first clip for the wire harness, the inner peripheral wall of the clip preferably has an arc shape exceeding 180 degrees and not more than 300 degrees, and the width direction of the clip is preferably 25 to 35 mm.
Furthermore, among the plurality of chambers sandwiched between the inner peripheral wall and the outer peripheral wall and partitioned by the partition wall portion, a chamber having no bottom wall portion is provided with a wire harness as in the first wire harness clip. You may make the electric wire group to comprise penetrate.

The wire harness clips of the first and second inventions are preferably molded from polypropylene (PP), polyamide (PA), and ABS resin.
The wire harness clip of the second invention may be formed of an elastomer, high hardness EPDM or silicon.

Examples of other components mounted on the automobile include a phosphorus hose, pipes, hoses, and a wire harness that are pivoted in the vehicle width direction in the instrument panel.
In particular, as the component to which the second wire harness clip is attached, a wire harness trunk line in which an electric wire provided with a terminal splice portion to be inserted into the clip chamber is branched.

It is preferable that the inner surface of the inner peripheral wall is provided with ribs for absorbing gaps between the anti-slip and mating parts, and / or the inner surface of the inner peripheral wall is provided with anti-slip texture.
According to the above configuration, the clip can be prevented from sliding in the width direction or rotating in the circumferential direction with respect to the part by the ribs and / or the embossing on the inner surface of the inner peripheral wall of the clip, and the clip can be prevented from being fixed to the part. It can be positioned and held in position.
The rib also functions to absorb a gap between the component and the inner surface of the inner peripheral wall, and can absorb the intersection of the components.

It is preferable that a fixing piece for winding a tape on a wire harness or attaching a tie band protrudes from one end face in the circumferential direction of the inner peripheral wall or outer peripheral wall.
According to the said structure, a clip can be easily attached to a wire harness by fixing a wire harness to the said fixed piece with a tape or a tie band.

A plurality of chambers sandwiched between the inner peripheral wall and the outer peripheral wall and partitioned by the partition wall portion are distributed through the main wires of the wire harness or the branch wires.
In addition, a terminal splice portion in which a plurality of electric wire ends are welded or crimped is inserted into a part or all of the plurality of chambers sandwiched between the inner peripheral wall and the outer peripheral wall and partitioned by the partition wall, and The terminal splice part is embedded in the waterproofing agent by filling the waterproofing agent.
As described above, one clip is provided with a chamber that allows the wire harness of the wire harness to pass therethrough and a chamber that accommodates the terminal splice portion, so that one clip can have various functions.

As described above, according to the present invention, the electric wire group of the wire harness is dispersed and inserted in the space sandwiched between the inner peripheral wall and the outer peripheral wall of the C-shaped cross section, and / or the terminal splice portion of the electric wire group is dispersed. Since it is externally fitted and fixed to a component mounted on the vehicle in the accommodated state, the wire harness fixed to the component does not protrude greatly from the component. Thereby, even if there is no sufficient space around the component, the wire harness can be efficiently routed in a narrow space.
Further, since the clip is externally fixed to the component, it is not necessary to provide a locking portion on the clip and fix the clip to the component. Therefore, it is not necessary to provide a locking structure such as a locking hole in the component, and the work can be facilitated even if it is attached at a position where it cannot be seen, and the clip can be easily removed when the automobile is disassembled. it can. Further, when the component is a reinforcing member such as a phosphorus hose, there is no need to provide a locking structure, so that the strength does not decrease.
Furthermore, since the lead-in bending portion that is easily bent at one end of the inner peripheral wall is provided, when the clip is externally fixed to the part, the lead-in bending part is sufficiently bent so that the clip is attached to the part. Work can be facilitated.

Embodiments of the present invention will be described with reference to the drawings.
FIGS. 1 to 5 show a first embodiment of the present invention, in which a C-cylinder-shaped clip 10 includes a group of electric wires W constituting a wire harness W / H routed in an instrument panel in chambers S1 and S2. In such a state, it is fitted to the phosphorus hose 30 that is a cylindrical reinforcing member pivoted in the vehicle width direction in the instrument panel. As shown in FIG. 1, a plurality (two in this embodiment) of clips 10 are attached to the phosphorus hose 30 at intervals in the length direction of the phosphorus hose 30, and the wire harness W / H between the clips 10 is connected to the phosphorus hose 30. We route along.

  As shown in FIG. 2, the clip 10 is curved in a C-shaped cross section, and has an inner peripheral wall 11 provided with a bent portion 11 a at one end of an arc, and a first hinge portion 12 from the other end of the arc of the inner peripheral wall 11. A C-shaped cylinder comprising an outer peripheral wall 13 having a second hinge portion 13a provided between the first hinge portion 12 and the tip, and having a C-shaped cross section that is folded back to the outer periphery via the inner space 11 and surrounds the inner peripheral wall 11 with a space S therebetween. It has a shape. An L-shaped locking piece 14 provided with a locking claw 14a on the inner surface of the front end protrudes from the outer surface of the inner peripheral wall 11 where the leading bent portion 11a is provided with a required dimension. Is provided with a latching claw 15a that latches with the latching claw 14a of the latching piece 14 on the inner surface and a latching frame 15 that covers the tip of the latching piece 14. The lock portion 16 including the locking piece 14 and the locking frame 15 can open and close the inner peripheral wall 11 and the outer peripheral wall 13 with the first hinge portion 12 and the second hinge portion 13a as fulcrums.

On the outer surface of the inner peripheral wall 11 and the inner surface of the outer peripheral wall 13 of the clip 10, partition walls 17 and 18 are provided so as to partition the space S sandwiched between the inner peripheral wall 11 and the outer peripheral wall 13 at opposing positions. A locking claw 18a projecting on both sides is provided at the tip of the partition wall 18 provided on the inner surface of the outer peripheral wall 13, while the partition wall 17 provided on the outer surface of the inner peripheral wall is a pair of wall portions sandwiching the partition wall 18 of the outer peripheral wall 13. The latching claw 17a is provided on the inner surface at the front end of each wall portion. The partition wall portion 18 of the outer peripheral wall 13 is inserted between the wall portions of the partition wall portion 17 of the inner peripheral wall 11 so that the locking claw 18a and the locked claw 17a are locked to each other. A space S sandwiched between the inner peripheral wall 11 and the outer peripheral wall 13 is divided into chambers S1 and S2.
The partition portions 17 and 18 are provided on the first hinge portion 12 side with respect to the second hinge portion 13a, and the inner peripheral wall with the second hinge portion 13a as a fulcrum in a state where the partition portions 17 and 18 are locked to each other. 11 and the one end side provided with the lock portion 16 of the outer peripheral wall 13 can be opened and closed.

The leading bent portion 11a of the inner peripheral wall 11 has an arc having the same diameter as that of the other portion of the inner peripheral wall 11 on the base side close to the locking piece 14, while the distal end is bent outwardly. The opening part which becomes the insertion port becomes wider so that the phosphorus hose 30 can be guided into the interior surrounded by the inner peripheral wall 11. A plurality of grooves 11b are provided in the outer surface of the leading bent portion 11a and the outer surface of the inner peripheral wall 11 on the other end facing the leading bent portion 11a, and the phosphorus hose 30 is clipped. When the inner peripheral wall 11 is inserted into the inner peripheral wall 11, the inner peripheral wall 11 at the portion where the groove 11 b is provided is bent outward.
On the inner surface of the inner peripheral wall 11, the wire harness W / H is inserted in a total of three locations, one end side where the leading bent portion 11 a is provided, the other end side where the first hinge portion 12 is provided, and the intermediate position thereof. A rib 19 for absorbing a gap with the anti-slip and counterpart component having a triangular cross-section extending in the corresponding width direction is projected, and a non-slip texture 20 is applied between the ribs 19 on both sides. .

The inner peripheral wall 11 of the clip 10 has an arc shape of 280 degrees, and the width L1 of the opening for inserting the phosphorus hose 30 is made smaller than the diameter L2 of the phosphorus hose 30.
Furthermore, the width of the clip 10 in the wire harness W / H insertion direction is set to 30 mm.

Next, a method for inserting the wire harness W / H into the clip 10 will be described.
First, as shown in FIG. 4A, the inner peripheral wall 11 and the outer peripheral wall 13 are opened with the first hinge portion 12 and the second hinge portion 13a of the clip 10 as fulcrums.
Next, as shown in FIG. 4B, the wire harness W / H is placed in the space closer to the first hinge portion 12 than the partition walls 17 and 18 in the space S sandwiched between the inner peripheral wall 11 and the outer peripheral wall 13. A part of the electric wire group W <b> 1 is configured, and in this state, the outer peripheral wall 13 is rotated toward the inner peripheral wall 11 with the first hinge portion 12 as a fulcrum, and the partition walls 17 and 18 are locked to each other. Thus, the electric wire group W1 is inserted into one chamber S1 surrounded by the inner peripheral wall 11, the outer peripheral wall 13, and the partition walls 17 and 18.
Finally, as shown in FIG. 4C, the wire harness W / H is configured in the space S between the inner peripheral wall 11 and the outer peripheral wall 13 and closer to the lock part 16 than the partition parts 17 and 18. In this state, the outer wall 13 is rotated to the inner wall 11 side, and the lock unit 16 is engaged with the lock. Thereby, the electric wire group W2 is inserted into the other chamber S2 surrounded by the inner peripheral wall 11, the outer peripheral wall 13, and the partition walls 17 and 18.
The wire group W (W1, W2) of the wire harness W / H inserted through the clip 10 is a trunk line of the wire harness W / H or a branch line branched from the trunk line.

Next, a method for attaching the clip 10 to the phosphorus hose 30 through the wire harness W / H will be described.
As described above, the clip 10 is attached to the phosphorus hose 30 in the instrument panel while the wire harness W / H is passed through the clip 10.
Specifically, as shown in FIG. 5 (A), by inserting the phosphorus hose 30 into the opening between one end and the other end of the inner peripheral wall 11 of the clip 10 where the guiding bending portion 11a is provided, the guiding bending portion 11 is inserted. As shown in FIG. 5B, the phosphorus hose 30 is pushed into the inner peripheral wall 11, and the clip 10 is externally fitted and attached to the phosphorus hose 30. At this time, the tip of the rib 19 projecting from the inner surface of the inner peripheral wall 11 abuts on the outer peripheral surface of the phosphorus hose 30 to prevent the clip 10 from sliding in the length direction and the circumferential direction of the phosphorus hose 30, and the phosphorus hose 30. Dimensional tolerances are absorbed.
In the phosphorus hose 30 of the present embodiment, only the tip of the rib 19 is in contact with the outer peripheral surface of the phosphorus hose 30 out of the inner peripheral surface of the clip 10, but when the clip 10 is externally fitted to a phosphorus hose having a large diameter. The entire inner peripheral wall 11 bends outward, so that not only the rib 19 but also the inner peripheral surface of the inner peripheral wall 11 that has been subjected to the graining 20 abuts the outer peripheral surface of the phosphorus hose 30.

According to the above configuration, since the clip 10 is externally fitted and fixed to the phosphorus hose 30 mounted on the vehicle in a state in which the wire group W of the wire harness W / H is dispersed and passed through the space S in the clip 10, The wire harness W / H fixed to the phosphorus hose 30 is routed substantially uniformly on the outer peripheral surface of the phosphorus hose 30 and does not protrude locally from the phosphorus hose 30. Thereby, even if there is no sufficient space around the phosphorus hose 30, the wire harness W / H can be efficiently routed in a narrow space.
Moreover, since the clip 10 is externally fitted and fixed to the phosphorus hose 30, it is not necessary to provide a locking portion on the clip 10 and fix it to the phosphorus hose 30. Therefore, it is not necessary to provide a locking structure such as a locking hole in the phosphorus hose 30, and the strength of the phosphorus hose 30 does not decrease. Moreover, even if it is the attachment in the state which cannot see the clip 10 to the phosphorus hose 30, an operation | work can be made easy and the clip 10 can be easily removed at the time of dismantling of a motor vehicle.

Furthermore, since the guiding bent portion 11a provided at one end of the inner peripheral wall 11 is sufficiently bent when attached to the phosphorus hose 30, the opening portion of the clip 10 into which the phosphorus hose 30 is inserted is greatly expanded, and the clip 10 is connected to the phosphorus hose 30. Installation work can be facilitated.
Furthermore, the partition walls 17 and 18 that partition the space S sandwiched between the inner peripheral wall 11 and the outer peripheral wall 13 protrude from the outer surface of the inner peripheral wall 11 and the inner surface of the outer peripheral wall 13 and are locked to each other. It is difficult to deform in the middle of the circumferential direction, and the wire group W that has passed through the space S is not bitten by the partition walls 17 and 18.
In the present embodiment, the clip 10 is provided with two chambers, but a plurality of partition walls may be provided to provide three or more chambers.

FIG. 6 shows a first modification of the first embodiment.
In this modified example, fixing pieces 21 and 22 for tape winding or tie band attachment are projected from one end face in the width direction corresponding to the insertion direction of the wire harness W / H of the clip 10. One fixed piece 21 protrudes at a position corresponding to the chamber S <b> 1 of the inner peripheral wall 11, while the other fixed piece 22 protrudes at a position corresponding to the chamber S <b> 2 of the outer peripheral wall 13.
After passing the electric wire group of the wire harness through the clip 10, a tape or a tie band is wound around the electric wire group together with the fixing pieces 21 and 22 to fix the clip 10 to the electric wire group.
According to the said structure, the clip 10 can be easily attached to the required location of an electric wire group.

Specifically, as shown in FIG. 8 and FIG. 9, a bottom wall portion 23 projects from one end in the width direction of the inner peripheral wall 11 corresponding to the chamber S2 toward the outer peripheral wall 13 side. When the inner peripheral wall 11 and the outer peripheral wall 13 are in a closed state, one end of the chamber S2 is closed by the bottom wall portion 23.

That is, the chamber S2 is in a state where only the other end opposite to the closed one end is opened, and the terminal splice portion 24 in which the end of the wire group W2 is resistance-welded is accommodated in the chamber 2 through the opening. Yes. After that, as shown in FIG. 9, the water stop agent 25 made of silicon is filled in the chamber 2, and the terminal splice portion 24 is embedded in the water stop agent 25 to stop the water.
Moreover, the electric wire group W1 is penetrated to the other chamber S1 as in the first embodiment.
The terminal splice part 24 may be formed by ultrasonic welding of the electric wire terminal, or a crimp terminal may be co-crimped.

According to the said structure, the terminal splice part 24 provided in the terminal of the electric wire group W2 can also be easily fixed to the phosphorus hose 30. FIG.
In this modified example, only one of the chambers is closed at one end, but all the chambers may be closed at one end and used as a clip exclusively for accommodating the terminal splice part.
In addition, since other configurations and operational effects are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted. Also in this modified example, a fixing piece similar to the second modified example may be provided.
