Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness molded protector for accommodating an electric wire bundle of a wire harness and adjusting and disposing the wire harness on the vehicle body or the like. The present invention relates to a clamp attachment structure for a wire harness molded protector for attaching a separate clamp for use with the clamp.

[0002]

2. Description of the Related Art A groove wire molded protector for a wire harness (hereinafter, simply referred to as a molded protector) has a structure in which a separate clamp having a locking head fitted and locked in a fitting hole of a vehicle body is retrofitted to a peripheral wall. Many of these are used, and among them, there is a known example of Japanese Utility Model Laid-Open No. 61-179148 for improving the mountability of the clamp to the molding protector and for securing the mountability of the clamp. That is, in this known example, an insertion window having an elastic locking plate and a locking window communicating with the insertion window are provided on the peripheral wall of the molded protector, and the locking head is erected on the lower side of the base. , A clamp provided with a locking leg that fits on the edge of the locking window, and the locking leg of the clamp is inserted into the insertion window of the molding protector and slidably transferred to the locking window for locking. At the same time, an elastic locking plate on the insertion window side is brought into contact with the locking leg portion in the locking posture to stabilize the mounting posture of the clamp to the molding protector.

[0003]

In the conventional clamp mounting structure described above, when the clamp is mounted on the molding protector, the elastic locking plate is bent downward while being pressed by the clamp and inserted into the insertion window. The work is a troublesome work with considerable insertion force and attention,
In addition, in a wire harness mass production line, since it is continuously performed with a quick processing tact, the operator is likely to be tired and inefficient, the fingertips are often damaged, and an elastic member that inadvertently bends downward is used. There is a problem in terms of quality and workability that damages the stop plate and the edge of the window and may result in improper installation.

Further, in the conventional mounting structure described above, since the structure of the clamp mounting portion of the molding protector is complicated, the cost of the molding die is high and the number of manufacturing days is long, which is one of the high costs of the molding protector. It is a factor.
The present invention provides a mounting structure that solves the above-mentioned drawbacks of the prior art.

[0005]

The clamp mounting structure for the molded protector for the wire harness of the present invention, which solves the above technical problems, is described as "a member for fitting and locking on a base part in a fitting hole of a vehicle body / device. When mounting a separate clamp with a toe installed upright on the outer periphery of the wire harness molded protector in a projecting posture, extend in the longitudinal direction of the wire harness molded protector on the wall portion of the wire harness molded protector. And a clamp track part for mounting the base part of the clamp in a vertically slidable state so as to be slidable, and further, in a sliding posture of the clamp track part of the clamp, a tip of the clamp track part presses against the clamp track part. Stopping and locking machine for the clamp, which includes a locking projection on the base side and a locking hole on the side of the clamp track part that receives the locking projection. The provided structure "is characterized.

[0006] Specifically, the above-mentioned clamp track portion is provided with an opposed inverted L-shaped two-row rail that is bulged on the peripheral wall of the molded protector for the wire harness, and is a main part of the clamp track portion, and between the rails. The structure that mounts the plate-shaped base of the clamp, or the T-shaped single rail that is bulged on the peripheral wall of the molded protector for the wire harness is used as the main part of the clamp track part, and is engaged with the upper flange of the T-shaped rail. A combination structure with a clamp base having a groove, or a slit provided on the peripheral wall of a molded protector for wire harness and a tray-shaped clamp rail formed below the slit. The structure of mounting the clamp base and projecting the locking head of the clamp from the slit is adopted. In the slidable clamp base is mounted vertically retaining state, the locking hole provided in a predetermined position by engaging the locking projection of the clamp, the predetermined position of the molding protector for a wire harness,
The structure is such that the clamp is stopped and locked, and the locking head is in a protruding posture.

[0007]

In the clamp mounting structure of the present invention having the above-described structure, the clamp base is inserted into the clamp track of the molding protector from the inlet of the clamp track and slid,
All that is required is to engage the locking mechanism, and further, the clamp in the sliding posture slides while pressing the locking projection of the base portion against the clamp track portion to reach the predetermined position,
Since the locking protrusion of the locking mechanism engages with the "click" in the locking hole, the locking feeling that the locking mechanism engages is very good, and the work of attaching the clamp to the molding protector is extremely simple. The determination as to whether the locking mechanism is engaged can be made extremely accurately. Therefore, in the mass production process of wire harnesses, even if the clamp mounting work is performed continuously with a fast processing tact, there is very little risk of damaging the members or improper mounting of the clamps. You can

Further, according to the clamp mounting structure of the present invention, the clamp mounted on the molding protector is locked by the clamp track portion in the vertical direction to prevent the clamp from slipping off, and the slide on the clamp track portion has the above-mentioned structure. Since it is locked by the stop mechanism, the mounting posture of the clamp with respect to the molding protector is mechanically stable. The clamp track portion may have a simple shape in which rails having the same cross section are continuous in a straight shape, and the locking hole provided therein may be post-processed if necessary. The shape is simpler than that of the conventional structure, and the molding die for resin molding the same can also be simplified.
