Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a junction box (J / B), a relay box (R / B), an electronic control unit box (ECU / B).
The present invention relates to an electric connection box for automobiles, which is particularly designed to be easily recycled and is applicable according to the vehicle type.

[0002]

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 junction boxes such as a junction box (J / B), a relay box (R / B), and an electrocuni 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.

FIG. 1 shows an example of the structure of a conventional electric junction box.
In the figure, reference numeral 1 denotes an electric connection box, and a fixing leg 3 is integrally formed on an electric connection box main body 2. The electric junction box 1 is provided with a large number of connector connecting portions 4. For the fixing foot 3,
A fixing hole 5 for attaching and fixing the electric junction box body 2 to the vehicle is formed. The electrical junction box 1 is attached and fixed to the vehicle body by fixing means 6 such as bolts, nuts or screws which have been conventionally used.

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 recovered, a pulling device such as a crane is used and the J-shaped hook is hooked on the electric connection box or the wire harness connected thereto. It was removed by pulling it up. However, at the time of removal, in the conventional electric connection box, the main body and the fixing foot are integrally formed, and the part where the fixing foot is provided is also predetermined, and since it was fixed, depending on the vehicle model. , It was often installed in a part that was difficult to remove. In such a case, it is necessary to manually remove the bolts, nuts, etc. used for fixing by the operator's work, and the workability is poor,
A lot of time was spent, resulting in an increase in dismantling costs.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to preferred examples. The electrical junction box according to the embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3. 2 is a perspective view schematically showing the structure of the electric junction box body, and FIG. 3 is an explanatory view of locking and fixing the fixing parts and the electric junction box body (A in FIG. 2).
It is a cross-sectional view taken along line A). The electrical junction box according to this embodiment includes an electrical junction box body 11 and a fixing part 12.
The electric connection box has a large number of connector connecting portions 13 and also has a plurality of fixing part inserting portions 14 for locking and fixing the fixing parts 12. In the example shown in the figure, only two fixing part insertion portions 14 are shown for the sake of simplicity of description, but in actuality, some additional fixing part insertion portions are provided. The fixing part 12 includes a locking fixing part 17 having a locking hole 16 for locking the fixing part lock part 15 of the fixing part insertion part 14 and a fixing hole 18 for fixing to the vehicle body. The vehicle fixed part 1 provided
It is composed of 9 and molded integrally.

The fixing part lock part 15 of the fixing part insertion part 14 provided in the electric junction box body 11 is for locking the locking hole 16 formed in the locking fixing part 17 of the fixing part 12. In addition to having the locking claw 20 of FIG. 3, the fixing part 12 is bent by the insertion of the fixing part 12 in the direction of the arrow in FIG. It is designed to ensure the locking and fixing of. The electrical connection box with the fixing parts 12 locked and fixed is
A fixing hole 18 formed in the fixing portion 19 of the fixing part 12 is fixed to the vehicle body through a fixing means (not shown) conventionally used such as bolts, nuts or screws.

As described above, the electric junction box of the present embodiment is characterized in that the electric junction box body 11 and the fixing parts 12 are separately formed, and that the electric junction box body 11 has a plurality of fixing parts. A parts insertion part 14 is provided so that the fixing parts 12 can be selectively locked and fixed to a part where the electric junction box body 11 can be easily removed when dismantling a discarded vehicle and / or a part corresponding to a vehicle type. Is.

In order to further diversify the fixing form, a plurality of kinds of fixing parts 12 having a shape corresponding to the shape of the part of the vehicle body to be mounted are prepared. It is preferable to make it selectively usable depending on the shape of the region of the vehicle type. Another example shape is shown in FIG. 4, which is, of course, exemplary and can take various forms.

More preferably, the structure of the fixing part 12 is formed so that the electric junction box body 11 can be easily removed when dismantling a discarded vehicle. This easy-to-remove structure is, for example, as shown in FIG.
5 is thinned (FIG. 5 (a) shows the fixing part of the above-mentioned embodiment), or is formed by forming a groove (not shown) which can be easily removed. In this case, the plate thickness and the dimensions of the groove are set so that the fixing to the vehicle body can be maintained.

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 fixing parts and the electric junction box main body are locked and fixed by using the fixing part lock portion, but they are locked and fixed by various conventionally used fixing means such as screwing. be able to.

[0014]

As described in detail above, according to the present invention, the above-mentioned configuration is adopted. Therefore, the fixing parts are prepared separately from the electric junction box body, and the electric junction box body is disassembled when the discarded vehicle is disassembled. Since it can be selectively locked and fixed to a part that is easy to remove and / or a part according to the type of vehicle, the electric connection box can be removed and collected efficiently when disposing of a discarded vehicle, the dismantling time can be shortened, and the dismantling cost can be reduced. In addition, since it is possible to take a flexible locking and fixing form according to the type of vehicle, it is advantageous when the removal method is different depending on the vehicle. Further, since the mounting position of the fixing parts can be selected, the electric junction box body can be shared, and the electric junction box can be designed at low cost.
