Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protector for an electric wire used in a wire harness for a vehicle or the like, and in particular, enables to securely fix the electric wire inside the protector even if the amount of the electric wire inserted into the protector is different.

[0002]

[Prior art]

 Conventionally, this type of protector has been formed by resin molding in a gutter shape as shown in FIG. 5 (A), and the wire accommodating portion 1c surrounded by the bottom plate portion 1a and both side plate portions 1b of the protector 1c. A large number of electric wires are pierced through and the protector 1 is fixed to a vehicle body panel (not shown) or the like, and the electric wires W are routed along a required path.

After the electric wire W is inserted through the protector 1, as shown in FIG. 5B, the tape 2 is provided on the outer peripheral surface over the entire length direction from the one end opening 1d to the other end opening 1e. The wire W is wrapped and wrapped, and is held so that the electric wire W does not come out from the upper end opening 1f.

[0004]

[Problems to be solved by the device]

 Although the cross-sectional area of the electric wire accommodating portion 1c of the protector 1 is constant, the number of electric wires W to be inserted differs depending on the wiring location and the vehicle type. Usually, a high grade vehicle type has a large number of electric wires and a low grade vehicle type. Then the number of electric wires is small.

Therefore, as shown in FIG. 5B, when the number of the electric wires W is large and the electric wires W are inserted almost completely into the electric wire accommodating portion 1c, the electric wire W is wound by winding the tape 2. It is fixed in a state of being pushed into the inside of 1c. However, when the number of the electric wires W is small, as shown in FIG. 6, the electric wires W are not fixed in a fixed position inside the electric wire accommodating portion 1c, and the electric wires W are not fixed inside the electric wire accommodating portion 1c due to vibration during traveling of the vehicle. The wire moves, which causes noise, and the outer peripheral surface of the electric wire W is easily damaged.

Therefore, when there are few electric wires W to be inserted as shown in FIG. 6, as shown in FIG. 7, a protector having extension portions 1g protruding from both ends in the length direction of the bottom plate portion 1a is used to extend the extension. The electric wire W on the portion 1g is wrapped with another tape 2'to fix the electric wire W.

In this case, since the tape 2 needs to be wound around the side surface plate portion 1b of the protector 1 as well as around the extension portion 1g, there is a drawback that the number of working steps is very large.

Further, as described above, when the tape 2 is strongly wound around the entire outer periphery of the protector 1 to hold the electric wire, both side plate portions 1b of the protector which are substantially vertical to the bottom plate portion 1a are inclined inward. When the protector 1 is distorted and attached to the vehicle body panel, the protector 1 is attached in an inclined state with respect to the panel, which may cause interference with other interior materials.

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

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a gutter-shaped protector having a bottom plate portion and both side plate portions, and a pair of cutouts facing a part of the both side plate portions with a required interval from the upper end of each. Insert a wire into the wire housing that is surrounded by the bottom plate and both side plates, and then wrap tape around the bottom plate and the outer surfaces of the thin parts on both sides. (EN) An electric wire protector having a structure for fixing an electric wire by tilting it depending on the amount of electric wire that accommodates a thin portion.

It is preferable that the inner surface side of the thin portion is 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 shaved. Further, it is preferable that the thin portion is provided up to the vicinity of the bottom plate portion, and the lower end on the bottom plate portion side is further provided with a thin hinge portion by cutting the outer surface side.

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

[0013]

[Action]

 In the protector described above, 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 in the portion where the thin portion is provided. When this tape is wound, the thin-walled parts on both sides are laid inwardly close to each other. At that time, when the amount of wire is large, the thin-walled parts on both sides are fastened with tape on the upper side of the wire with a small amount of collapse, while when the amount of wire is small, the thin-walled part on the upper side of the wire has a large amount of collapse. The parts are tightened with tape. If the amount of electric wire is very small, tape is tightened with the thin portion wrapped.

In this protector, since the tape is wound only on the thin wall portion, the side plate portion which is originally thick has no deformation such as inclining inward due to the winding with the tape, and the thick side plate portion is attached to the vehicle body. When fixed to the panel, the protector can be prevented from being tilted and fixed to the vehicle body panel.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. The protector 10 is integrally molded of resin and has a gutter shape having a bottom plate portion 11 and both side plate portions 12 and 13 projecting upward from the left and right ends of the bottom plate portion 11, and is provided at the center of the both side plate portions 12 and 13. Thin portions 14 and 15 are provided facing each other.

At both ends in the length direction L of the thin portions 14 and 15, there are cuts 16 and 17 between the thick side plate portions 12 a and 13 a from the upper end to the vicinity of the bottom plate portion 11, respectively. It is separated from the side plate portions 12a and 13a. As shown in FIG. 2, the thin-walled portions 14 and 15 have approximately half the thickness W on the outer side with respect to the thick side plate portions 12a and 13a. Since it is made of resin, the thin-walled portions 14 and 15 have a thickness of about half from the beginning.

Further, at the lower ends of the thin portions 14 and 15, hinge portions 14a and 15a, which are thin on the outer surface side, are 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 tape 2 is wound around the portions where the thin portions 14 and 15 are provided. When the tape 2 is wound, the thin portions 14 and 15 are tilted inward by the hinge portions 14a and 15a and pressed against the upper side of the inserted wire W.

At that time, if there are many electric wires W, the amount of collapse of the thin portions 14, 15 is small, as shown in FIG. 4 (A). On the other hand, if the number of electric wires W4 is small, as shown in FIG. 4 (B), the thinned portions 14 and 15 have a large amount of collapse, and the collapsed thin portions 14 and 15 are pressed onto the small amount of the electric wire W and the tape 2 It is tightened by.

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

[0021]

As is apparent from the above description, when the wire protector according to the present invention is used, the thin portion falls inward according to the wire amount and fixes the wire, so that the wire amount is somewhat concerned. Instead, the electric wire can always be fixed inside the protector so that it cannot be moved.

Moreover, since the tape is wound only on the thin-walled portion of the side plate portion, the tape winding work is reduced, and the side plate portion is not deformed in the portion not wound with the tape because the side plate portion is inclined inward. Therefore, by fixing the undeformed side plate portion to the vehicle body panel, there is also an advantage that the protector can be fixed to the vehicle body panel without tilting.
