BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire protector used for a wire harness for a vehicle or the like, and more particularly, to a wire protector which can be securely fixed inside a protector even if the amount of wires inserted through the protector is different. It is to be.

[0002]

2. Description of the Related Art Conventionally, a protector of this type is shown in FIG.
As shown in FIG. 1, a large number of electric wires are passed through a wire accommodating portion 1c surrounded by a bottom plate portion 1a and both side plate portions 1b of the protector 1, and the protector 1 is attached to the body panel. (Not shown) or the like, and the electric wire W is routed along a required route.

[0005] After the electric wire W is inserted into the protector 1, as shown in FIG. 5 (B), the tape 2 is applied to the outer peripheral surface over the entire lengthwise direction from the one end opening 1 d to the other end opening 1 e.
Is wrapped and wound so that the electric wire W does not come out of the upper end opening 1f.

[0004]

The cross-sectional area of the wire housing 1c of the protector 1 is constant, but the wire W
The number of cables differs depending on the wiring location and the type of vehicle. Generally, a high-grade vehicle has a large number of electric wires, and a low-grade vehicle has a small number of electric wires.

Therefore, as shown in FIG. 5 (B), when the number of the electric wires W is large and the electric wire W is almost fully inserted into the electric wire accommodation portion 1c, the electric wire W is wound around the tape 2 so that the electric wire W is not inserted. It is fixed while being pushed inside. However, when the number of the electric wires W is small, as shown in FIG. 6, the electric wire W is not fixed in a fixed position inside the electric wire accommodation portion 1c, and the electric wire moves inside the electric wire accommodation portion 1c due to vibration during running of the vehicle. This causes noise and causes the outer peripheral surface of the electric wire W to be easily damaged.

Accordingly, when the number of electric wires W to be inserted is small as shown in FIG. 6, the protector provided with extension portions 1g projecting from both ends in the longitudinal direction of the bottom plate portion 1a as shown in FIG. The electric wire W on the portion 1g is wound around with another tape 2 'to fix the electric wire W.

In this case, it is necessary to wind the tape 2 around the side plate 1b of the protector 1 and also around the extension 1g.

Further, as described above, when the electric wire is held by strongly wrapping the tape 2 around the entire outer periphery of the protector 1, both side plates 1b of the protector which are substantially perpendicular to the bottom plate 1a are inclined inward. When the protector 1 is attached to the vehicle body panel, there is a problem that the protector 1 is attached in a state of being inclined with respect to the panel, and interference with other interior materials easily occurs.

The present invention is intended to solve the above-mentioned conventional problems. Even if the amount of electric wires to be inserted into the protector is different, these electric wires can be securely fixed, and when the tape is wound around the entire protector. The purpose is to eliminate the distortion of the protector that occurs.

[0010]

In order to achieve the above object, the present invention provides a gutter-shaped protector having a bottom plate portion and both side plate portions. A pair of cuts are made at intervals, and a thin portion is formed between these cuts, and after inserting the electric wire into the electric wire accommodating portion surrounded by the bottom plate portion and both side plate portions, a tape is applied to the outer peripheral surface of the bottom plate portion and both side thin portion portions. To provide an electric wire protector having a configuration in which the electric wire is wound and fixed in such a manner that the electric wire is fixed according to the amount of electric wire for accommodating the thin portions on both sides.

It is preferable that the thin portion has the inner surface side flush with the inner surface of the thick side plate portion in a state where the outer surface side of the side plate portion is cut off. Further, it is preferable that the thin portion is provided up to the vicinity of the bottom plate portion, and a hinge portion which is further thinned by cutting the outer surface side is provided at the lower end on the bottom plate portion side.

Further, the position where the thin portion is provided is arbitrary in the longitudinal direction. Further, the number of the thin portion may be one, or a plurality of the thin portions may be provided at a required interval.

[0013]

In the above protector, after inserting the electric wire into the electric wire accommodating portion, the tape is wound around the outer peripheral surface including the bottom plate portion around the portion where the thin portion is provided. When this tape is wound, the thin portions on both sides are fallen inward close to each other. that time,
When the amount of wire is large, the thin portions on both sides are tightened with tape on the upper side of the wire with a small amount of fall, while when the amount of wire is small, the thin portion on the top of the wire with a large amount of fall is taped Be tightened. When the amount of the electric wire is very small, the thin portion is fastened with a tape in a wrapped state.

In the present protector, since the tape is wound only on the thin portion, the original thick side plate portion is not deformed such as being inclined inward by winding with the tape, and the thick side plate portion is attached to the vehicle body. When the protector is fixed to the panel, the protector can be prevented from being inclined and fixed to the vehicle body panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. The protector 10 is integrally formed of resin and has a gutter shape having a bottom plate portion 11 and both side plate portions 12 and 13 projecting upward from both left and right ends of the bottom plate portion 11. Thin portions 14 and 15 are provided to face each other.

At both ends of the thin portions 14 and 15 in the length direction L, there are cuts 16 and 17 between the thick side plates 12a and 13a from the upper end to the vicinity of the bottom plate 11, respectively. It is separated from the side plates 12a and 13a. Each thin part 1
As shown in FIG. 2, 4 and 15 are thick side plate portions 1 on the outer surface side.
The thickness W is approximately half of that of 2a and 13a in a state where the outer surface side is cut off. Since the thin portions 14 and 15 are formed by resin molding, the thickness of the thin portions 14 and 15 is substantially half from the beginning.

At the lower end of each of the thin portions 14 and 15, hinge portions 14a, 1
5a is provided to make it easy to fall inward.

As shown in FIG. 3, after the electric wire W is inserted into the protector 10 having the above structure, the thin portion 14,
The tape 2 is wound around the portion provided with the reference numeral 15. The tape 2
The thin portions 14 and 15 become hinged portions 14
a, 15a, and is pressed down above the inserted wire W.

At this time, if the number of the electric wires W is large, as shown in FIG. On the other hand, if the number of the electric wires W4 is small, as shown in FIG.
5 has a large amount of fall, and the thinned portions 14 and 15 that have fallen are tightened by the tape 2 while being pressed onto the small electric wire W.

In the above embodiment, only one thin portion 14, 15 is provided in the length direction. However, when the protector is long, it is preferable to provide a plurality of the protectors at a required interval. When fixing the protector 10 to a vehicle body panel, it is preferable to fix a thick side plate portion which is not a thin portion to the panel.

[0021]

As is clear from the above description, when the electric wire protector according to the present invention is used, the thin portion falls down inward according to the amount of the electric wire to fix the electric wire. The wire can always be immovably fixed inside the protector.

Moreover, since the tape is wound around only the thin portion of the side plate, the operation of winding the tape is reduced, and the portion where the tape is not wound is not deformed because the side plate is inclined inward. Therefore, by fixing the undeformed side plate portion to the vehicle body panel, the protector can be fixed to the vehicle body panel without being inclined.
