Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting posture of a wire harness mounted on the outer periphery of a wire harness, and a projecting locking head is locked in a fitting hole of a vehicle body / equipment to dispose the wire harness on the vehicle body. The present invention relates to a wire harness clamp used to arrange and hold a wire.

[0002]

2. Description of the Related Art A wire harness clamp is provided with a locking head that is locked to a locking portion such as a fitting hole of a vehicle body or a device at a mounting portion mounted on the outer periphery of a wire harness by tape winding or a winding band. It has a basic shape that is set up, is attached at a required interval in the longitudinal direction of the wire harness, and the locking head is locked to the vehicle body / device to arrange and hold the complicated layout shape of the wire harness. It is supposed to do.

However, the span of the locking head (the distance between the locking heads of the wire harness clamps attached to the wire harness and adjacent to each other) does not match the distance between the locking portions of the vehicle body or the like. However, it is unavoidable that it will be practically difficult and that a slight “deviation” will occur between the two. Therefore, it is preferable to make the locking head span and the standing position of the locking head adjustable, and there are known examples disclosed in Japanese Utility Model Laid-Open No. 63-99091 and Japanese Utility Model Laid-Open No. 4-109275.

That is, the former known example is a combination of a mounting member having a long groove guide groove formed in the longitudinal direction of the wire harness and a clip member having a locking head for the vehicle body. Has a structure in which the locking head span and the like can be adjusted by moving the guide groove along the guide groove. The latter one is a combination of a mounting member and a clip member, and is provided in the mounting member. Guide rail as a rail,
The back plate of the clip member is configured to be movable, and similarly has a structure that enables span adjustment and the like.

[0005]

A wire harness to be mounted on a vehicle body / equipment is bent and bent in a complicated three-dimensional posture along a narrow mounting route provided along a wall surface of the vehicle body and locked. Therefore, a strong external torsional force may be applied during installation, and it may be locked and held in the vehicle body or the like in the twisted posture.

The above-mentioned known wire harness clamp attached to the twisted wire harness has the following problems. That is, since the known example has a structural feature of guiding and sliding the clip member along the long guide portion on the side of the attachment member, the attachment member attached to the outer periphery of the wire harness is By the twist, the guide part also exhibits a twisting posture that follows,
The sliding movement of the clip member may be difficult or impossible, and in the latter one, there is a risk that the clip member may be disengaged from the mounting member and lose the clamping function due to the twist of the long rail-shaped guide portion.

The present invention solves the above-mentioned drawbacks of the prior art, and provides a clamp for a wire harness in which the adjustment of the locking head span and the adjustment of the locking head standing position can be performed easily and accurately.

[0008]

A wire harness clamp according to the present invention which solves the above technical problems has a structure in which a locking head for a vehicle body / device is provided upright in the center of a rectangular board, and the length of the board is long. A clamp member whose both end portions on the side are formed into a pair of attaching plate portions, and a connecting portion which slidably fits the attaching plate portion slidably in the long side direction, and to the wire harness. Consisting of a fixing member provided with a fixing means of
The structure is such that one of the pair of attachment plate portions is provided with a stopper portion for restricting the relative slide amount of the connection portion and the attachment plate portion in the connection posture ".

Then, both ends of the clamp member are loosely fitted and connected to the connecting portion of the fixing member for fixing to the wire harness, and the clamp member is attached in the longitudinal direction of the wire harness.
By moving within the restricted slide stroke, the clamp span between the adjacent wire harness clamps is adjusted, and the standing position of the locking head with respect to the wire harness is adjusted.

The fixing member is formed into a crocodile-shaped connecting portion so as to be engaged and connected from a side edge of the clamp member, or a short tubular connecting portion is fitted from an end edge of the clamp member. The connection mode is adopted, and the fixing to the wire harness is performed by a winding band wound around the outer periphery of the wire harness or a tape winding wound together with the wire harness.

[0011]

In the wire harness clamp of the present invention having the above structure, the attachment plate portions at both ends of the clamp member are slidably connected to the connecting portion of the pair of fixing members for fixing the wire harness, and Since only one of the attachment plate portions regulates the slide amount, the clamp member whose both ends are loosely fitted and held by the pair of fixing members becomes movable in the longitudinal direction of the wire harness within the regulated slide stroke, It is possible to freely adjust the clamp span and the locking head position.

Even if the wire harness disposed on the vehicle body / apparatus is twisted and deformed, and the relative position of the connecting portion of the pair of fixing members fixed to the outer periphery of the wire harness collapses,
Since the joint length between the connecting portion and the attachment plate portion of the clamp member is relatively small, the influence on the slidability of the clamp member due to the collapse is small, and further, the connecting portion and the attachment plate portion. Since the loose fitting amount of the portion can be set to an appropriate amount in advance, it is extremely unlikely that the slide adjustment of the clamp member will be obstructed when the expected deformation of the wire harness after the arrangement is performed. Can be effectively secured.

Further, the fixing member and the clamp member are
Since they are interconnected by means of through loose fitting and are prevented from coming off by the stopper portion, the connection posture is mechanically stable, and even if the wire harness is twisted and deformed after being mounted on the vehicle body / device. The clamp function is stable because there is no danger that the clamp member will come off the fixing member.
