Description

[Detailed Description of the Invention] The present invention relates to a harness protector used for electrical wiring in a vehicle.

A harness made of multiple single wires covered with a spring or an outer jacket is used for wiring to electrical equipment in a vehicle.The harness is wired along the inner wall of the engine compartment, the interior wall of the vehicle, and the inner wall of the rear of the vehicle body, and is used for positioning, fixing, and direction. Regulations are done using clips that are attached to the vehicle body, but the intermediate parts between the clips are loose and may rub against the inner wall due to engine vibration or running vibration, which is not desirable in terms of protecting the harness. Contact with the inner wall of the harness may generate a scraping sound, causing noise.

In order to cope with the above problems, it has been conventionally done to support the harness at the appropriate place with a protector, and the protector is formed of a short rubber tube and has ring-shaped flanges near both ends in the axial direction, and the protector is attached to the harness. The tape is inserted into the necessary parts of the protector, and the tape is wound around the extension part, which has a plurality of axial slits extending from both ends of the flange part of the protector, to tightly connect the extension part and the circumference of the harness adjacent thereto. Perform longitudinal fixation. A locking clip in the form of a band of steel plate provided on the wall of the vehicle body is wound in a loop around the flange portions of the protector fixed around the circumference of the harness, and the protector is supported on the wall surface of the vehicle body.

Such conventional means require the work of winding a clip provided on the vehicle body wall between the flange portions of the protector in a loop shape, and the winding also needs to be done accurately, making the work cumbersome and complicated. Since this is done on the assembly line, improvements are desirable. In particular, since the clip is simply wrapped around the flange of the protector, the loop may loosen over time due to repeated vibrations, and the clip may go over the flange and cause the protector to shift.
There is a risk that it may come off, so improvement is desirable in this respect as well.

This invention was developed with the above considerations in mind when it comes to mounting and supporting the harness protector on the vehicle body.The purpose of this invention is to securely support the mounting of the harness protector on the vehicle body side clip, and to prevent vibrations and the passage of time. It does not come off even when twisted, and the clips are easy to attach to the protector.
To provide a harness protector which prevents the occurrence of incomplete attachment or attachment that is likely to come off.

In order to achieve the above object, the present invention provides a flange portion near both ends of a tube-shaped main body that covers the outer periphery of the harness, and also provides a bridge portion in the axial direction between a part of the circumference of the flange portion. The gist is that a slit that is open in the circumferential direction is provided in a part of the outer periphery of the main body, and a band-shaped clip on the vehicle body side is inserted and locked into the slit.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional side view of the protector 1, and FIG. 2 is a partially broken end view.

The main body 2 of the protector 1 is made of rubber or synthetic resin and has a tube shape. The slits 204... having a length in the axial direction open to the axial direction are provided, and the slits 204... are provided radially at both ends 202, 203 at equal angular intervals of four slits, and the slits 204... It forms a land shape that is separated by , making it easy to bend in the direction of diameter reduction.

In front of both ends 202, 203 of the main body 2, ring-shaped flanges 3, 4 projecting radially outward.
The flange portions 3 and 4 are provided at an intermediate portion of the main body 2 and spaced apart from each other in the axial direction. Flange parts 3, 4
A narrow bridge 5 is provided in the axial direction between a part of the circumference of the main body 2 so as to connect the flange parts 3 and 4, and an outer periphery 205 between the bridge 5 and the flange parts 3 and 4 of the main body 2 is provided.
A slit 6 which opens both sides in the tangential direction is provided between.

In the above, the protector 1 is fitted to the outer periphery of the harness 7 at a proper position, and both axial ends 2 of the protector 1 are fitted.
02,203 An adhesive tape (not shown) is wound around the outer periphery of the protector 1 and the outer periphery of the portion adjacent thereto.
to the harness 7. In each of FIGS. 3 to 5, for convenience of explanation, both ends 202 and 203 are shown in a bare state without being wrapped with tape.

3 to 5 show an example of mounting and supporting the protector 1 on a vehicle body.

In FIG. 3, for example, one end 801 of a band-shaped clip 8 made of a thin steel plate is welded or the like to the inner wall of the engine compartment, and the clip 8 is attached to the periphery of the intermediate portion between the flange portions 3 and 4 of the protector 1. Bend it into a loop 802 and wrap it around the leftover piece 80
3 through the slit 6 and press the bent portion 802 to reduce the diameter, and adjust the outer diameter of the bent portion 802 to the flange portions 3 and 4.
be smaller than the outer diameter of This state is shown in FIG.

In Figure 4, the clip 9 with one end 901 welded to the vehicle body side is not wrapped half-wound around the outer periphery of the protector 1 as described above, but the length of the clip 9 is shortened, and the middle or tip of the clip 9 is slitted. 6 and bent into a V-shape on the side to attach and support the protector 1. In the embodiment, a wide locking portion 9 is provided at the tip of the clip 9 to prevent it from slipping out from the slit 6.
02 was established.

FIG. 5 shows the base 1 attached to the vehicle body side via the holder 103.
01 is attached and supported, the clip 10 is wrapped 102 around the outer periphery between the flange parts 3 and 4, and the tip of the clip 10 is inserted into the slit 6.

As described in detail above, according to the present invention, when attaching and supporting the intermediate portion of the harness to the vehicle body, etc., the clips are inserted into the slits of the protector and engaged with the slits of the protector, instead of simply bending the clips. Even if the winding becomes loose or goes beyond the flange, it will not come off or shift, and the harness protector can be stably mounted and supported over a long period of time. The work is easy, as all you have to do is bend it, wrap it around the outside, and then insert it into the slit.Furthermore, even if you don't have to be very precise when wrapping the clip, you can get a clip that will not interfere with the installation and retention, making it easy to assemble the vehicle. It has many advantages such as being convenient for line work.
