2. Description of the Related Art As is well known in the art, in order to form a circuit for connecting a wire harness to electrical components in an automobile,
Electrical connection boxes such as a junction box (J / B), a relay box (R / B), and an electronic control unit box (ECU / B) are attached. These electric junction boxes have electric circuits (formed of metal bus bars) such as circuits for power distribution inside the case,
A plurality of connector connecting portions for electrical connection are formed on the outside of the case. The electric connection box is provided with fixing feet for mounting and fixing to the vehicle body, and is fixed by bolts, nuts, screws or the like. These electric connection boxes are attached to a reinforcement provided in front of the vehicle, a foot portion inside the vehicle compartment, an engine room, a metal bracket (stay), and the like.

FIG. 1 shows an example of a conventional fixing structure for an electric junction box of this type. 1A is a front view and FIG. 1B is a side view. The illustrated example is a case where fixing is performed by using reinforcement. Reference numeral 11 in the drawing denotes an electric connection box, and fixing feet 3A and 3B for attaching the electric connection box 1 to the reinforcement 2 are provided on the upper and left sides of the electric connection box.
Fixing holes 4A and 4B are formed in the fixing feet 3A and 3B at the same position in the vertical direction. On the other hand, on the reinforcement 2 side, bolts 5A and 5B for fixing the electric junction box 1 are attached to the left and right at the same position in the vertical direction. Then, the bolts 5A and 5B are inserted into the fixing holes 4A and 4B of the fixing feet 3A and 3B, and the nuts 6A and 6B are tightened and fixed.
It was being attached to Rinforce 2. In addition, 7 is an instrument panel and F is a hook of a lifting device such as a crane.

On the other hand, recently, the recognition of environmental problems has increased,
Effective recycling of resources has become a major issue. Such issues are no exception for discarded vehicles. Not only wire harnesses used by electronic vehicles but also electric connection boxes connected to them use a large amount of metal materials such as copper, so that recycling cannot be ignored at present.

By the way, in dismantling a discarded vehicle, when the electric connection box is removed from the vehicle body and collected, a pulling device such as a crane is used, and the J-shaped hook is hooked on the electric connection box and pulled up to remove. It will be.
However, at the time of removal, the electric junction box is firmly fixed to the vehicle body with bolts, nuts, etc., so the electric junction box will not withstand pulling and will not come off, or if strong force is applied, the electric junction box will be destroyed, There were many cases of scattering. Therefore, if it is firmly fixed, the operator must manually remove the bolts, nuts, etc., which is poor workability and consumes a lot of time.
It caused an increase in dismantling costs.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to preferred examples. FIG. 2 shows an electric connection box according to an embodiment of the present invention, FIG. 3 (a) is a front view showing a state in which the electric connection box is attached with a reinforcement, and FIG. 3 (b) is a disassembled vehicle disassembly. A side view showing how the electric connection box is detached with a hook of a lifting device such as a crane at a time. Reference numeral 11 in the drawings denotes an electric connection box, and fixing feet 13A and 13B for fixing the electric connection box 11 to the reinforcement 12 are provided on the upper and left sides of the electric connection box. The lengths of the fixing legs 13A and 13B in the vertical direction are different from each other on the left and right, and the fixing holes 14A and 14B are formed at different positions in the vertical direction, that is, offset positions. The vertical offset amounts of the fixing holes 14A and 14B are determined by the hook F of a lifting device such as a crane when the electric connection box 11 is removed during vehicle disassembly.
When applying a pulling force with
The force is appropriately distributed at A and 13B so that the short fixing foot 13B is destroyed first, and then the long fixing foot 13A is destroyed. This offset amount depends on the size and shape of the electric junction box 11, but is generally 15 to 30 m.
It is preferably about m. On the reinforcement 12 side, corresponding to the fixing holes 14A and 14B of the electric junction box 11,
Bolts 15A and 15B for fixing the electric junction box 11 are attached to the left and right from positions offset in the vertical direction. And these bolts 15A, 15B
Is inserted into the fixing holes 14A and 14B of the fixing feet 13A and 13B, and tightened and fixed with the nuts 16A and 16B, whereby the electric junction box 11 is fixed to the reinforcement 12. In addition, 17 is an instrument panel.

With the structure as shown in FIG. 1, since the fixing portion of the electric junction box 1 with respect to the reinforcement 2 is at the same position on the left and right, a machine that is acted by the hook F of the lifting device such as a crane when dismantling a discarded vehicle. The force is fixed on the feet 3A and 3
It was added evenly with B, and it withstood firm fixing with bolts and nuts, and the recovery of the electrical junction box 1 did not go smoothly.
However, with the configuration as shown in FIGS. 2 and 3, when a pulling force is applied by the hook F, the force is sequentially transmitted to both the fixing feet 13B and 13A, and the short fixing feet 13B.
Is first destroyed, and then the long fixing foot 13A having a bending allowance is destroyed, so that the removal and recovery can be smoothly performed, and the problems of the prior art can be solved.

Although the present invention has been described in detail based on one embodiment, the present invention is not limited to the above embodiment, and various modifications and changes can be made. For example, in the above, the case where the electric connection box is attached to the reinforcement has been described, but the technique of the present invention is to attach the electric connection box to the vehicle body such as the foot of the vehicle compartment, the engine room, and the metal bracket (stay). It can be applied to the attachment and fixing of the electrical junction box in various parts. In particular, it is effective for mounting and fixing to a place where the force to be removed is evenly transmitted in the conventional mounting and fixing of the electric junction box. Also, in the above, the vertical length of the fixing foot was changed to offset the left and right fixing holes in the vertical direction, but the vertical length of the fixing foot is the same, and The positions of the holes may be different in the vertical direction and may be offset. Further, in the above, the bolts are provided on the vehicle body (reinforce) side and the nuts are tightened and fixed. However, conversely, the receiving screw holes are formed on the vehicle body (reinforce) side to fix the electrical connection box side. You may insert a bolt from the foot fixing hole side and tighten and fix it. In addition, various conventionally known fixing methods can be used.

[0011]

As described above in detail, according to the present invention, the fixing portion of the fixing leg of the electric junction box is offset to the left and right in the vertical direction and is attached to the vehicle body. When a pulling force is applied by a hook of a lifting device such as a crane during dismantling work, the force is sequentially transmitted to the left and right fixing feet, the short fixing feet are destroyed first, and then the long fixing feet are It will be destroyed and can be removed smoothly. Therefore, the efficiency of the dismantling work can be improved, the dismantling time can be shortened, and the dismantling cost can be reduced.
