DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector for a wire harness, and more particularly to a protector having a holding portion such as an electric connection box or a connector connected to a branch wire from the wire harness.

[0002]

2. Description of the Related Art FIG. 4 shows a state in which a wire harness is protected by a conventional protector of this type.

The protector comprises a gutter-shaped protector body 1 for accommodating a wire harness W, and a flat cover 3 for closing an opening 4 on the upper surface of the protector body 1. Locking frames 7 are provided on both side walls 2 of the protector body 1, and lock arms 5 are provided on both side edges of the cover 3.
When the lock arm 5 is engaged with the locking frame 7, both are locked, and the cover 3 is fixed to the protector body 1. The lock arm 5 and the locking frame 7 are disposed at both ends in a direction in which the wire harness W extends (hereinafter, this direction is referred to as a “longitudinal direction”) and at an appropriate position therebetween.

At a side edge near one end in the longitudinal direction of the cover 3, a lead-out port 10 for leading a branch wire Wa from the wire harness W to the outside is provided so as to include the opening 4 of the protector body 1. ing. The outlet 10 is formed in a rectangular shape by a notch 10 a provided in the side wall 2 and a notch 10 b provided in the cover 3. A stop frame 7 is arranged.

The side wall 2 at the center in the longitudinal direction of the protector body 1
, A bracket 12 extending toward the cover 3 is provided upright, and the bracket 12 is provided with a connection box holding portion 14 so as to be located above the cover 3. The connection box holding portion 14 detachably holds an electric connection box 18 fitted with a connector 16 provided at a terminal of the branch electric wire Wa.

FIG. 5 is a perspective view showing the connection box holding section 14. As shown in FIG. The connection box holding portion 14 has a box shape with an opening at the top, has a hook wall 14 a defined by two slits 15 communicating with the opening side, and has a side surface 12 a of the bracket 12.
Are provided integrally. On the back side of the electric connection box 18, a frame-shaped mounting portion 19 that can be fitted to the hook wall 14a is provided. When the mounting portion 19 is fitted to the hook wall 14a, the mounting portion 19 It is stored and held in the interior 17 in a locked state.

When the wire harness is protected by such a protector, the wire harness W is housed inside the protector body 1 and then the branch wire Wa is led out of the outlet 10.
The cover 3 is put on the protector main body 1 while being guided to the outside, and the lock arm 5 is engaged with the locking frame 7 to fix the cover 3 to the protector main body 1. Then, the connector 16 provided at the end of the branch wire Wa is fitted into the electric connection box 18, and the electric connection box 18 is held by the connection box holding unit 14.

However, in such a protector, when the branch wire Wa is led out as shown in FIG.
There was a gap between the protector body 1 and the cover 3, from which the electric wire sometimes protruded. In addition, the branch wire Wa
When a strong pulling force acts on the lock arm 5, the locking projection 6 of the lock arm 5 comes off the locking surface 7a of the locking frame 7,
The cover 3 may fall off the protector body 1.

FIG. 7 shows another protector described in Japanese Utility Model Laid-Open No. 2-118415. This protector is provided with an auxiliary cover 31 that can be freely opened and closed by a hinge portion 31a at a part of the cover 3, and the branch wire is led out with the auxiliary cover 31 opened. Locking frames 33 are provided at both ends in the longitudinal direction of the cover 3, and locking protrusions 35 that engage with the locking frames 33 are provided on the protector body 1. On the fixed side of the cover 3, a locking frame 37 for fixing the cover 3 to the protector main body 1 when the auxiliary cover 31 is opened is provided.
Is provided with a locking projection 39.

According to such a protector, the locking frame 3
7 and the locking projection 39, the auxiliary cover 31
Can be prevented and the cover 3 can be prevented from floating even when the branch wire is led out.

[0011]

However, if the protector shown in FIG. 4 is to be prevented from floating by the same method as that shown in FIG. 7, the protector shown in FIG. Lock arm 25 having projection 26 and locking frame 27
Must be additionally provided. For this reason, the number of locks at the time of attaching the cover 3 may increase, and the workability of attaching the cover 3 may be deteriorated.

The present invention has been made in consideration of the above circumstances, and has as its object to provide a protector which has good cover mounting workability and can effectively prevent the cover from floating.

[0013]

According to the present invention, there is provided a protector body for housing a wire harness, and a cover for covering an opening of the protector body, and at least one of the protector body and the cover is branched from the wire harness. A protector provided with an outlet through which an electric wire is led out, a connection box holding portion for holding an electric connection box connected to the branch wire on the side of the protector main body, wherein the outlet is arranged to include the opening; , The connection box holding portion is arranged such that the electric connection box held by the connection box holding portion is close to the surface of the cover around the outlet.

[0014]

In the protector having the above structure, when the electric connection box is held by the connection box holding portion, the electric connection box is close to the surface of the cover around the outlet of the branch wire, so that the rise of the cover is prevented by the electric connection box. Hold down.

[0015]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention.
FIG. 2 is a side view of FIG. In this protector, a connection box holding portion 24 that holds the electric connection box 18 is disposed near the outlet 10. And this connection box holding part 2
4 is located closer to the surface 3a of the cover 3 than the conventional one, and when the electric connection box 18 is held by the connection box holding portion 24, the lower end surface 18a of the electric connection box 18 Cover 3 on the edge opposite to the lock portions 5 and 7 at the end)
In the vicinity of the surface 3a. The other configuration is the same as that of the conventional example shown in FIG. 4, and therefore, the same components are denoted by the same reference numerals and description thereof will be omitted.

According to the protector of this embodiment, when the electric connection box 18 is held by the connection box holding portion 24, the lower end face 18a of the electric connection box 18 is close to the surface 3a of the cover 3, so that the cover 3 Even if the airplane is going to float, the electric junction box 18 holds it down and reliably prevents the airplane from floating. Therefore, there is no possibility that a gap is generated due to the lifting and the wire protrudes. In addition, since the floating can be reliably prevented, it is not necessary to additionally provide a lock arm or a locking frame as shown in FIG. 8, and therefore, the cover 3 can be easily attached without increasing the number of locks. be able to.

In this embodiment, when the electric connection box 18 is held by the connection box holding portion 24, the lower end face 18a of the electric connection box 18 is arranged so as to be close to the surface 3a of the cover 3. The connection box 18 may be arranged so as to directly or indirectly contact or press the surface 3 a of the cover 3.

In this embodiment, the outlet 10 is formed by providing the cutouts 10a and 10b in both the side wall 2 and the cover 3. However, if the outlet 10 is arranged so as to include the opening 4, the present invention is not limited to this. The invention can be applied. That is, the notch 11 is formed only at the upper edge of the side wall 2 of the protector body 1 as shown in FIG.
a may be provided to form the outlet 11 and the cover 3
Only the outlet may be formed.

[0020]

As described above, according to the present invention,
The electric connection box can prevent the cover from floating, and can prevent the electric wires from protruding. Also,
In particular, since it is not necessary to increase the number of locks of the cover, the work of attaching the cover can be easily performed.
