Description

  The present invention relates to a harness protector structure, and more particularly, to a harness arrangement to be mounted on a vehicle, and to a protector protector structure that includes a clamp for attaching and holding the harness and protects the harness.

When wiring a harness to a vehicle, it is basically protected by winding a protective tube, and fixed at several points with clamps. In addition, in order to protect the wiring from external impacts and loads at the same time as attaching the harness, the wiring is partially attached and fixed to a base material such as a vehicle body panel or an outfitting part using a protector.
In addition, it is basic to use a dead space so that routing is as inconspicuous as possible, but conversely, it is arranged in a conspicuous place so as not to impair the appearance.
And as a protector provided in such a harness, the main part has a substantially annular harness holding part that is partially open, and the harness holding part is formed to be thin and closed by a flexible hinge. There is a harness protector provided with a lid-integrated clamp in which a lid portion is integrally provided in a main portion. (Patent Document 1 and Patent Document 2)

When the harness protector has surrounding structural parts on the base material to be mounted that prevent the lid from being opened and closed by the thin hinge of the clamp, it is necessary to set the dimensions of each part of the clamp to avoid mutual interference. The size of the part is shortened, or a sufficient height is given to the substantially annular harness holding part that affects the height of the hinge.
On the other hand, when mounting on the vehicle, the mounting of the harness and the mounting of the outfitting parts (for example, peripheral parts of the instrument panel) are performed individually rather than simultaneously. Harnesses that need to be routed throughout the vehicle are mounted at the earliest time, and then relatively large fittings that are mounted inside the vehicle are preferentially mounted. After mounting each, wiring, clamping, and installation work are performed sequentially while wiring the harness.

By the way, when the harness protector with a clamp is accommodated and installed using the internal space of the groove-shaped recess formed in the base material to be attached as an accommodation space, the harness protector should be installed without problems in the process of attaching the harness protector. The harness protector needs to take into account its structure and shape because it is necessary not only to be able to perform the rotation, but also to rotate the clamp lid without inconvenience when performing the subsequent clamping operation.
And when attaching a harness protector, the operation | movement with the position which is easy to have is performed naturally. However, when the harness protector is inserted into the housing space of the recess, the harness protector may be changed or the position may be shifted.
For example, in the case of a mounting structure that simply moves the harness protector straight toward the bottom of the recess, there is no need to change the holding position of the harness protector, and it is not often possible to hold the lid part carelessly. Absent.

However, when the insertion part is provided on the harness protector so as to face the side wall surface of the recess and is attached to the base material, the harness protector is directed to the side wall surface of the recess while being inserted into the housing space of the recess so as to face the bottom surface of the recess. If the work operation on the attachment, such as changing the direction to rotate, becomes necessary, it may happen that the lid portion that is opened carelessly is held. In such a case, there is a high possibility that a catch that cannot be caused by the open lid portion will occur between the surrounding structural portions.
And, when wiring, clamping, and attaching work to parts while wiring the harness after mounting on the vehicle, it becomes difficult to visually confirm the position and state, especially as the work on the lower back side of the instrument panel In the case of work, it is a groping work, and not only does the above-mentioned inconvenience easily occur during the clamping work, but there is a problem that it is difficult to confirm even if it occurs.

  An object of the present invention is to provide a harness protector that can perform a clamping operation without any inconvenience when routing a harness using an internal space such as a groove structure formed in a base material as an accommodation space.

  The present invention comprises a harness protector structure provided with a clamp having an integral lid portion as a main part by a thin hinge, and a harness is fixed by this clamp and held on a base material, while an insertion pin is provided on the harness protector. The engagement portion of the insertion pin is provided in the base material, the arrangement of the insertion pin is provided, and the clamp is provided, and the lid portion of the clamp has a shape along the hinge axis of the thin hinge and the lid portion is opened. In some cases, a rib that contacts the main portion of the clamp is provided.

In the harness protector structure of the present invention, the open lid portion can be prevented from coming into close contact with the main portion of the clamp, and the harness protector is not assembled to the base material without the lid portion being raised.
The harness protector structure according to the present invention can secure a space for inserting a finger by a rib between the open lid portion and the main portion of the clamp, so that the clamp can be fixed easily.
