Abstract

PURPOSE:To linearly mount a wire harness on a panel by curving the wire harness along the outer circumference of a curved part in a clamp, and fixing both side parts of the curved part in the wire harness to the bent parts of deflecting leg parts in the clamp. CONSTITUTION:When a clamp 4-1 is mounted on a wire harness W/H, the wire harness W/H is curved along the outer circumference of a curved part 4b, and both side parts of the curved part are fixed to the bent parts 4d of leg parts 4c with an adhesive tape 5. The mounting space L2 between the cramps 4-1 is set to the same as the space L1 between clamp holes in a panel 1 or slightly smaller than it. When the locking part 4a of the clamp 4-1 is engaged with the clamp hole of the panel 1, the wire harness W/H is relatively pulled in the arranging direction by the deflection of the leg parts 4c, and the wire harness W/H between the clamps 4-1 is made linear. Thus, the wire harness W/H never make contact with other parts near the panel 1 because it is never largely snaked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp capable of linearly attaching a wire harness to a panel.

[0002]

2. Description of the Related Art A wire harness for wiring various electric components is attached to a vehicle body panel of an automobile or the like. As shown in FIG. 7, the method of attaching the wire harness is as follows. The clamp holes 1a, 1 are attached to the panel 1 at regular intervals L1.
While opening a, the clamps 2 and 2 are attached to the wire harness W / H at intervals L2 corresponding to the clamp holes 1a and 1a of the panel 1, and the locking portions 2a and 2a of the clamps 2 and 2 are fixed to the above. The wire harness W / H is routed along the panel 1 by inserting and engaging the respective clamp holes 1 a, 1 a of the panel 1.

If the clamps 2 and 2 are attached to the wire harness W / H at an interval L2 that matches the interval L1 between the clamp holes 1a and 1a of the panel 1, the wire harness W / H between the clamps 2 and 2 will be Although it has a straight line shape, normally, in consideration of variations when manufacturing the wire harness W / H, the distance L1 between the clamp holes 1a and 1a (for example, 200 m
m), the distance L2 between the clamps 2 and 2 is set to be slightly wider (for example, 205 ± 5 mm).

Therefore, the clamp holes 1a of the panel 1 are
When the engaging portions 2a and 2a of the clamps 2 and 2 are inserted into and engaged with the clamp 1a, the wire harness W / H between the clamps 2 and 2 is in a slightly meandering state rather than a straight line.

[0005]

However, in the case where the wire harness W / H has a large variation at the time of manufacture and the distance L2 between the clamps 2 and 2 is too wide, as shown in FIG. There is a problem that the wire harness W / H between the clamps 2 and 2 meanders greatly and contacts other parts near the panel 1. As a countermeasure, it is possible to attach a synthetic resin molding protector to the wire harness W / H between the clamps 2 and 2.
Since the distance L2 is long, a large molding protector is required,
It cannot be installed in a narrow space and increases the cost.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a clamp for a wire harness that allows the wire harness to be linearly attached to a panel.

[0007]

In order to achieve the above object, the present invention provides a panel in which clamp holes are formed at regular intervals, and a clamp is attached to a wire harness at intervals corresponding to the clamp holes of the panel. By engaging the clamp protrusion of the clamp with the clamp hole of the panel,
A clamp for attaching a wire harness to a panel, in the vicinity of a clamp protrusion of the clamp, a bending portion that bends the wire harness, and both side portions of the wire harness that are curved by the bending portion are fixed, It is intended to provide a clamp for a wire harness, which is provided with a pair of legs having flexibility in a wire harness installation direction. At least one of the curved portion or the leg portion may be provided with a hook claw portion that can sandwich and fix the wire harness from the side.

[0008]

According to the present invention, the wire harness is curved along the curved portion in the vicinity of the clamp protrusion of the clamp, and both side portions thereof are respectively fixed to the pair of leg portions, and the clamp mounting intervals are set to the panel clamp. Set the hole spacing to be the same or slightly shorter. As a result, the curved portion of both clamps can absorb a large meandering length of the wire harness, and the flexible leg portion pulls the wire harness relatively in the wiring direction. It becomes a straight line. By providing the hook claw portion on the curved portion or the leg portion, the wire harness can be fixed with one touch only by sandwiching it from the side.

[0009]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 to 3 show the clamp 4-I of the first embodiment. The clamp 4-I is made of synthetic resin and has a locking portion 4a which is inserted into the clamp hole 1a of the panel 1 and engages with the clamp hole 1a. The locking portion 4a is projected from a semicircular substrate 4g. U-shaped curved portion 4b along the peripheral edge of the curved portion 4 and
It has a pair of leg portions 4c, 4c which extend downward from both ends of b and are bent outward. Each of the legs 4c,
4c is bendable in the wiring direction of the wire harness W / H (see a in FIG. 1).

Connect the clamp 4-I to the wire harness W /
To attach to H, as shown in FIG.
The wire harness W / H is curved along the outer periphery of the wire harness W / H, and both side portions of the curved portion of the wire harness W / H are fixed to the bent portions 4d, 4d of the leg portions 4c, 4c with the adhesive tape 5, respectively.

Mounting interval L2 of the clamp 4-I
Is set to be equal to or slightly shorter than the interval L1 (for example, 200 mm) between the clamp holes 1a and 1a of the panel 1 (for example, L2 = 190 to 200 mm).

Further, the engaging portion 4 of each clamp 4-I, 4-I
When a and 4a are inserted into and engaged with the clamp holes 1a and 1a of the panel 1, the wire harness W / H is relatively pulled in the wiring direction due to the flexibility of the legs 4c and 4c, so that both clamps 4- The wire harness W / H between I and 4-I becomes linear.

As a result, the wire harness W / H does not meander significantly, so that it does not come into contact with other parts near the panel 1. Further, since it is not necessary to attach a large-sized molding protector, the cost can be reduced and the wire harness W / H can be routed even if the mounting space is small.

FIG. 4 shows a clamp 4-II of the second embodiment. The difference from the clamp 4-I of the first embodiment is that the hook claw portion 4f, which can fix the wire harness W / H by sandwiching it from the side to the top of the curved portion 4b and the upper portions of the legs 4c, 4c. ..., 4f are provided. As a result, the wire harness W / H can be fixed with one touch simply by sandwiching the wire harness W / H into each hook claw portion 4f from the side.

FIG. 5 shows a clamp 4-III according to the third embodiment. The clamp 4-III extends from a board portion 4g provided with a locking portion 4a to one side (left side in the drawing) and is folded back, and a leg 4c is raised upward from an end of the leg portion 4c. The curved portion 4b and the leg portion 4c extending from the end of the curved portion 4b to the other side (right side in the figure). When the clamp 4-III is used, the wire harness W / H is fixed to the leg portions 4c, 4c with the adhesive tape 5. In the clamp 4-III, only the leg portion 4c on the other side (on the right side in the figure) can bend in the wiring direction a of the wire harness W / H.

FIG. 6 shows a clamp 4-IV of the fourth embodiment. The clamp 4-IV is provided with two locking portions 4a, 4a spaced apart from each other on an elongated base plate portion 4g, and a top portion along the end face of the base portion 4g and curved portions 4b bent from both sides of the top portion. The hook protrusion 4f is provided on the top of the curved portion 4b. When using the clamp 4-IV, the wire harness W
/ H is curved along the inner circumferences of the curved portion 4b and the legs 4c, 4c, and the wire harness W / H of the curved portion 4b is fixed by sandwiching it from the notches 4h, 4h to the hook claw portion 4f. The wire harnesses W / H of the legs 4c and 4c are fixed with the adhesive tape 5, respectively.

In each of the clamps 4-I to 4-IV,
The locking portion 4a and the curved portion 4b are integrally formed, but the curved portion 4b and the leg portion 4c are integrally formed on the board 4g having the locking portion 4a projecting from the locking portion 4a as a separate body. If the molded product is detachably attached, it is possible to select and use one type of locking portion 4a having different curvatures of the curved portion 4b and different lengths of the leg portions 4c.

[0018]

As is apparent from the above description, the wire harness clamp of the present invention bends the wire harness along the bending portion and fixes both side portions of the wire harness to the pair of leg portions. The mounting interval is the same as the interval of the clamp holes on the panel or slightly shorter. Therefore, since the wire harness is pulled relatively in the wiring direction by the flexible legs of both clamps, the wire harness between both clamps becomes linear, so that the wire harness can be linearly attached to the panel. it can.

As a result, the wire harness does not meander greatly, so that it does not come into contact with other parts near the panel. Further, since it is not necessary to attach a large-sized molded protector, the cost can be reduced and the wire harness can be routed even if the mounting space is small.
Further, when the hook claw portion is provided on the curved portion or the leg portion of the clamp, the wire harness can be fixed with one touch only by sandwiching it from the side.
