Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness clamp guide, and more particularly to a clamp guide for positioning and attaching a wire harness consisting of a large number of electric wires to a clamp provided on a vehicle body panel of an automobile. Even if the outer diameter of the wire harness changes, the wire harness is closely fitted to the wire harness so that the wire harness can be immovably fixed.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, when a wire harness W / H composed of a large number of electric wires is held by an annularly curved clamp 1 attached to a vehicle body panel of an automobile, the wire harness W / H is A clamp guide 2 for positioning and holding is attached to the outer peripheral surface of H, and the clamp 1 is wound around the outer periphery of the clamp guide 2 to route the wire harness W / H inside the automobile.

The clamp guide 2 is made of resin, and as shown in FIG. 7, a cylindrical member having flanges 2a and 2b for guides at both ends is divided in half to divide a pair of semi-cylindrical members 2c and 2d. Is integrally formed in a state in which one end of is connected by a thin hinge 2e.

The clamp guide 2 is connected to the wire harness W.
8A, the tape 3 is wound around the clamp guide mounting position of the wire harness W / H a required number of times, as shown in FIG.
The outer diameter of H is set to be substantially the same as or slightly larger than the inner diameter of the clamp guide 2. Then, the other end of the pair of semi-cylindrical members 2c and 2d is opened with the hinge 2e as a fulcrum, and is fitted onto the outer peripheral surface of the wire harness W / H as shown in FIG. 8B. Is held in pressure contact with the clamp guide 2 and the wire harness W /
It is fixed so that H does not move. In this state, the clamp 1 formed by annularly forming a plate material is spread and wound around the outer peripheral surface between the collar portions 2a and 2b of the clamp guide 2, and the tip of the clamp 1 is placed near the winding start point around the clamp guide 2. The wire harness W / H is positioned and arranged on the vehicle body panel by fixing with a screw.

[0005]

As described above, since the conventional clamp guide 2 has a constant inner diameter, when the outer diameter of the attachment position of the wire harness W / H is small, the wire inside the clamp guide 2 is small. The harness W / H moves and the mounting position is displaced. On the other hand, when the outer diameter of the wire harness W / H is large, the clamp guide 2 cannot be attached to the outer circumference of the wire harness W / H. Therefore,
A plurality of types of clamp guides having different inner diameters are provided, and the tape 3 is wound around the clamp guide mounting position to adjust the outer diameter of the wire harness to correspond to the inner diameter of the clamp guide 2 as described above. However, since tape winding is a manual operation, variations easily occur.

Therefore, the tape winding operation must be performed while confirming the number of times the tape 3 is wound using a check gauge so that the outer diameter of the mounting position accurately corresponds to the inner diameter of the clamp guide 2. The workability is very poor. Further, since a plurality of types of clamp guides 2 having different inner diameters are required, the number of parts is increased, which causes a problem of high cost.

The present invention has been made in view of the above problems, and in a clamp guide for positioning and holding a wire harness consisting of a large number of electric wires in a clamp provided on a vehicle body panel, the outer diameter of the wire harness is It is an object of the present invention to provide a clamp guide that can easily hold a wire harness in a fixed state even if it changes.

The present invention provides a clamp guide for a wire harness.

According to the above-described wire harness clamp guide, the semi-cylindrical members are externally fitted to the clamp guide mounting position of the wire harness in an open state in which the ends of the respective semi-cylindrical members are separated from each other with the thin hinge serving as a fulcrum, and the hinge is used as a fulcrum. The end portion of the semi-cylindrical member is operated in the closing direction, and the locking piece protruding from the divided one end of the collar portion is selected and locked to the locked portion at the other end.
That is, the diameter of the clamp guide corresponding to the wire harness diameter can be increased or decreased by selecting the locking position between the locking piece and the locked portion. Therefore, unlike the conventional example, the tape winding work for making the wire harness diameter correspond to the inner diameter of the clamp guide becomes unnecessary.

A sawtooth-shaped locking portion is continuously formed on the locking piece, while a sawtooth-shaped locking groove is continuously formed on the outer peripheral surface of the collar portion at the other end as the locked portion. There is. (Claim 2) According to the clamp guide, by operating the pair of semi-cylindrical members in the closing direction, the locking portion of the locking piece and the locking groove of the locked portion formed in a sawtooth shape are required. Since it is selectively locked at the position, mounting workability is improved.

The locking piece is formed in a thin band shape, and the locking hole is provided in parallel with the band-shaped locking piece, while the locking projection is provided on the outer peripheral surface of the collar portion at the other end. (Claim 3) According to the clamp guide, the pair of semi-cylindrical members is operated in the closing direction to lock the wire harness in the locking hole at the position corresponding to the locking protrusion while the outer periphery of the wire harness is clamped. Thus, the cylindrical member made of the semi-cylindrical member can be attached to the wire harness in close contact with it.

At least one of the pair of semi-cylindrical members is provided with a bellows portion which expands and contracts in the circumferential direction. (Claim 4) According to the clamp guide, the range corresponding to the wire harness diameter is widened by expanding and contracting the bellows portion.

A large number of small projections are provided on the inner peripheral surfaces of the pair of semi-cylindrical members. (Claim 5) According to the clamp guide, since the small protrusion is in contact with the wire harness, the wire harness is less likely to slip,
Even when the wire harness vibrates due to vibration or the like that occurs during traveling in the state of being installed in the automobile, the wire harness does not move easily, and the positional deviation of the wire harness can be more reliably prevented.
