Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to an improvement of a molded protector for protecting a wire harness installed in an automobile or the like.

(Problems to be solved by conventional technology and ideas) In the wiring of wire harnesses for automobiles, etc., due to the diversification of vehicle specifications, the number of wires in the wire harness used varies depending on the grade of the same car model. Therefore, there is considerable variation in the diameter of the harness.

Therefore, if you use one type of protector to handle various wire harnesses with different numbers of wires,
When the number of wires is small, the wires move inside the protector and cause abnormal noise when driving the car.
When the number of wires is large, it becomes difficult to accommodate the required number of wires in the protector during harness assembly and wiring.

In the past, in order to eliminate this problem, protectors of different sizes were prepared depending on the number of wires, but this had disadvantages such as increasing the number of parts and man-hours for parts arrangement and parts management. It was hot.

(Means for solving the problems) The present invention was created in view of the above-mentioned conventional drawbacks.
It is an object of the present invention to provide a protector that can appropriately adjust the wire housing space in the protector according to the number of wires of various types.

The protector of the present invention is a molded protector for a wire harness consisting of a main body having a substantially U-shaped cross section and a lid that closes an upper opening of the main body. It is characterized by having an appropriate number of notches, and a wire holding plate bent to be accommodated in the notch hole in the main body and suspended from both side walls of the main body.

If the bent electric wire holding plate is in a curved state, it is preferable that the overall thickness is appropriately thinner than that of the main body, and if it is bent, it is preferable that the bent portion is made thinner. .

It is preferable that the wire holding plate accommodated in the main body in a bent state be expanded to a shape equivalent to the maximum outer diameter of the main body when the wire bundle is accommodated.

(Function) The wire holding plate is bent and molded so that it fits inside the main body while hanging from both side walls of the main body.
The wire accommodating space of the main body after molding is smaller than the accommodating space of the original protector having a U-shaped outer shape. However, even when a harness with a diameter exceeding the accommodation space is inserted, the accommodation space can be expanded by pushing the bent wire holding plate downward. In that case, if it is a curved wire holding plate, it can be made to have a moderately thin overall shape so that it can bend downward more easily, and if it is a bent wire holding plate, the bent part can be made thin so that the bent part can act as a hinge. This makes it easier to expand the holding plate.

In addition, the pushed down holding plate itself has an elastic action that tries to return to the state when it was molded, and the wire bundle housed in the protector is pushed upward by the holding plate, but the upper opening of the main body is closed by the lid. Since the wire bundle is closed by the body, the wire bundle is compressed between the holding plate and the lid body within the body and is properly fixed within the body.

When the wire holding plate is expanded to a shape equivalent to the maximum main body outer diameter when accommodating the wire bundle, the wire accommodating space can also be changed to the same maximum main body inner diameter.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. In FIG. 1, reference numeral 1 denotes a main body that houses a wire bundle therein, and a lid 3 that closes the upper opening of the main body 1 is connected to the main body 1 via a hinge part 7. ing.

The locking claw 8 of the lid body 3 is inserted into a locking hole 9 provided in the upper part of the outer wall of one side 2' of the main body 1, and the locking surface 10 of the locking claw 8 is located at the lower opening edge of the locking hole 9. 11, and the lid body 3 is fixedly locked to the upper opening of the main body.

An appropriate number of notches (three in this embodiment) are made at appropriate locations in the longitudinal direction of the main body 1 from the bottom surface 4 to the side walls 2, 2', and the notch holes 5 are provided with the side walls 2, 2'.
A wire holding plate 12 which is suspended and bent into a substantially W-shaped cross section is provided at the cutout end 6 of the wire holding plate 2'.

The protector having the wire holding plate is molded in the state shown in FIG.
The connecting portions 13 and 15 of both side walls and the bent portion 14 of the center portion of the holding plate are formed to be slightly thinner than the main body.

FIG. 2 shows a cross-sectional view of the wire bundle 20 housed in the protector shown in FIG. 1. Due to the wire holding plate 12, the wire accommodating space of this protector is narrower than that of a conventional U-shaped protector that does not have a holding plate, but even if a bundle of wires with a harness diameter exceeding the space is accommodated, Since the thin bent portion 15 can be expanded and the holding plate 12 can be expanded downward until it can completely accommodate the harness, a storage space can be set according to the harness diameter.

Even if the harness diameter becomes thicker and the wire holding plate is pushed down, an upward elastic force acts on the holding plate to return to its original molded state, pushing the wire bundle upwards, causing the holding plate to lower. The wire bundle 20 is firmly fixed between the holding plate 12 and the lid 3 without creating an extra gap between the wire bundle and the lid.

As shown in Fig. 3, the wire holding plate 12 of this embodiment can be expanded to the same size as the maximum U-shaped outer shape, and the wire accommodating space can be expanded in multiple stages up to the same maximum body diameter depending on the diameter of the wire bundle. Can be stretched. The shape of the wire holding plate of the present invention is not limited to that of this embodiment, and various shapes can be considered. For example, as shown in FIG. 4, the four locations of the side wall connecting portions 16, 19 and the chevron-shaped bent portions 17, 18 of the holding plate may be formed into a thin chevron shape with a substantially trapezoidal cross section; As shown in FIG. 5, the entire wire holding plate may be formed into a thin and curved shape, and the holding plate may be pressed down while being bent.

Even if the shape of the wire holding plate is changed, the wire accommodating space within the protector changes appropriately according to the harness diameter, and the wire bundle is clamped between the lid and the holding plate and fixed within the protector.

(Effects of the invention) According to the protector of the invention, the wire housing space can be changed appropriately according to the harness diameter to be accommodated, so even if the number of wires changes, it can be handled with one type of protector, and parts arrangement, It requires less administrative effort.

The wire bundle housed in the protector is firmly fixed between the wire holding plate and the lid, so even when the number of wires is small, the wire bundle will not move inside the protector, causing abnormal noise during operation. can be prevented.
