Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a protector for protecting a wire harness used for electric wiring of an automobile,
More specifically, it relates to a protector for a wire harness having a branch line.

(Prior Art) Conventionally, as this type of protector, a protector as shown in FIG. 5 is generally used. In the case of the same figure, the protector
20 is formed in a gutter shape with a lid so that the main line of the wire harness 21 can be stored, and a cutout groove is formed in a part of it.
22 is opened so that a branch line 23 can be drawn out from this.

(Problems to be solved by the invention) For example, a connector or the like is often provided at the tip of the branch line 23. However, when the branch line 23 is connected to another electric device or the like, the branch line 23 is considered in consideration of work convenience. It is better to draw out the extra amount. However, if the branch line 23 is pulled out more than necessary in consideration of the work allowance, the branch line 23 will be connected in a loose state. Therefore, in the conventional case, there is a risk of interference with surrounding members, and there is a problem that the coating may be broken if it interferes with a member having a sharp edge portion. It suffices to push it into the protector 20 after connection, but this is not easy, and in the end the branch line had to be left loose.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to prevent a slack in a branch line of a wire harness and prevent interference with other peripheral members. Is to provide.

(Means for Solving the Problems) In order to solve the above problems, the protector of the wire harness in the present invention is configured as follows.

That is, in the protector body formed so that the wire harness having the branch line can be housed, a window portion for drawing out the branch line is provided along the longitudinal direction of the wire harness. An elastic holding piece for holding the branch line, which also extends along the longitudinal direction of the wire harness and has one end thereof as a free end, is provided in the window portion so as to be elastically bendable and deformable inward and outward of the protector body. . The amount of flexural deformation of the elastic holding piece is set so that the branch line can be pulled out by at least the length required for the connecting work.

(Operation) Store the main line and branch line of the wire harness in the protector body in advance. At this time, the branch line is held by the elastic holding piece.

Next, the protector is fixed to the body of the automobile or the like. After that, when connecting the branch line, the elastic holding piece is pulled out while flexing outward, and is released after the completion of the connection work, the elastic holding piece returns, and as a result, the branch line does not bend and is almost in a tension state. Will be wired.

(Example) An example will be described with reference to the drawings.

1 to 4, the protector 1 is integrally formed of a synthetic resin material, and the main body 2 is formed in a gutter shape so as to accommodate a wire harness 4 having a branch line 3. A lid 6 is formed on the opening edge on one side of the main body 2 via a hinge edge 5. The lid 6 can cover the opening portion of the main body 2, and a pair of locking claws 7 are provided on the edge of the free end side opposite to the hinge edge 5, and the corresponding outer surface on the main body 2 side is provided. It is detachable from the receiving portion 8 provided. Further, a window portion 9 for drawing out the branch line 3 of the wire harness 4 is provided on the surface on which the receiving portion 8 is provided. In the window portion 9, an elastic holding piece 10 for holding the branch line 3 by binding it with tape T or the like is formed laterally along the side surface of the main body 2.
The elastic holding piece 10 is allowed to bend outward with the side from which the branch line 3 is pulled out as a free end. Also, the window 9
At the free end side of the elastic holding piece 10 in FIG.
It is open as 11.

Reference numeral 12 is a connector connected to the tip of the branch line 3.

When the wire harness 4 is attached to the protector 1 having the above configuration, the wire harness 4 is stored in the main body 2 with the lid 6 opened. At this time, the branch line 3 is pulled out from the outlet 11, and the branch line 3 is bound to the elastic holding piece 10 by using tape T or the like. Then, the lid 6 is closed and both the locking claws 7 are engaged with the receiving portions 8 to lock the lid 6.

Next, the protector 1 is attached to the body using an appropriate fixing means.

On the other hand, in the work of connecting the connector 12 of the branch wire 3 to the electric device W to which the branch wire 3 is to be connected, when the branch wire 3 is pulled toward the electric device side, the elastic holding piece 10 bends outward, whereby the third wire. As shown in FIG. 4 and FIG. 4, the wiring length S1 when the branch line 3 is connected is added to the length (work allowance) S2 required to perform the connection work with a space,
This branch line can be drawn out. Therefore, the connection work can be performed without any trouble as in the conventional case.

When the branch line 3 is released after the connection work is completed, the elastic holding piece 10 returns to its original position by its elasticity (fourth position).
(Figure state). Along with this, the branch line 3 that was tied up
Is accommodated in the protector body 2, and as a result, the above-mentioned work allowance is absorbed and the branch line 3 is wired in a substantially tensioned state.

(Effect of the Invention) According to the present invention, when the branch line is pulled out from the inside of the protector body for the connection work, the branch line is attached to the elastic holding piece of the protector body for a predetermined length,
This elastic holding piece can be pulled out while bending. Therefore, the branch line can be smoothly pulled out from the inside of the protector main body and a predetermined connection work can be performed without forcibly deforming the elastic holding piece. Further, after the connection work is completed, the work amount of the extra branch line is absorbed by the elastic return of the elastic holding piece, and the branch line is held in a properly stretched state with almost no slack.
