Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary fixing structure for an electric connection box which is effective for mounting an electric connection box mainly used for electric wiring of an automobile.

[0002]

2. Description of the Related Art When an electric connection box is attached to a counterpart structure such as a vehicle body of an automobile, it is fixed to the vehicle body by bolting. This installation work may have to be done with the electric junction box tilted, and it is necessary for the worker to tighten the bolts while manually supporting the electric junction box. There is a problem that it deteriorates.

Therefore, in order to facilitate this mounting work, Japanese Unexamined Utility Model Publication No. 4-47328 discloses a method shown in FIGS.
As shown in FIG. 2, there is proposed a temporary fixing structure for an electrical connection box that allows the mounting work to be performed on the mating panel while the electrical connection box is temporarily fixed. In the temporary fixing structure of the electric junction box shown in FIG. 6, a hooking piece b is provided so as to project from the upper end of the electric junction box main body a, and the hooking piece b is brought into contact with the back side of the panel c as the mating structure. Thus, the electric junction box body a is temporarily prevented from tilting in the state before the bolting for the mounting work.

However, the hooking piece b is in a position where it comes into contact with the nut e or the like for fastening the bolt d penetrating the panel c after the electric connection box main body a is fixed by bolting. , There is a risk that noise will be generated due to vibration when the automobile is running, or that the hook pieces b will be scraped off due to friction to generate fine pieces, which will enter the electric junction box and damage the electric circuit. There are problems such as

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and the mounting work of the electric junction box can be carried out smoothly, and the electric connection box is mounted on the vehicle body to receive vibrations during traveling. When you hit it, abnormal noise is generated due to friction,
An object of the present invention is to provide a temporary fixing structure for an electric junction box, which is excellent in durability and reliability without causing fine pieces due to abrasion.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a temporary fixing hole provided in a mating structure when fixing the electrical junction box to the mating structure. In the temporary fixing structure of the electrical connection box, the temporary locking arm dedicated to the temporary fixing protruding from the box is loosely engaged to temporarily lock the electrical connection box to the mating structure. provided with a top and bottom of the fixing bracket to the junction box, and the upper
The temporary locking arms are provided between the lower fixing brackets, and the temporary locking arms are provided with locking claws directed to the lower fixing brackets via the extension portions, and the temporary locking arms are provided via the fixing brackets. When the electric connection box and the mating structure are fixed to each other, the locking claw is separated from the back surface of the mating structure via a gap. The temporary locking arm is preferably attached to a temporary fixing bracket provided on the case of the electric junction box (claim 2).

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a side view showing an electric junction box A according to an embodiment of the present invention, and a side sectional view of a panel P as a mating structure to which the electric junction box A is attached. Electric connection box A
Includes various electric parts and wirings thereof inside the upper case 1 and the lower case 2, and as shown in FIG.
Is attached, each fixing bracket 3, 3 'in the upper right and lower portion of the upper case 1, temporary fixing bracket 4 is attached to the lower right.

Mounting holes 5 and 5'are formed in the fixing brackets 3 and 3 ', respectively, and a temporary locking arm 6 is provided in a protruding manner on the temporary fixing bracket 4. Reference numeral 7 denotes a connector provided on the upper wall 1a of the upper case 1. The panel P is provided with mounting holes 8 and 8'corresponding to the mounting holes 5 and 5'of the fixing brackets 3 and 3'of the electric junction box A, respectively, to temporarily lock the electric junction box A. A temporary fixing hole 9 formed in the shape of a square hole is opened at a position corresponding to the arm 6.

The temporary locking arm 6 is provided so as to project toward the lower case 2 in a direction substantially perpendicular to the upper wall 1a of the upper case 1,
A bracket for fixing the lower portion to the free end of the extension portion 6a.
A locking claw 10 is provided facing the door. Extension 6a
When the electric junction box A is fixed to the panel P,
The rear surface 11 of the panel P and the inner side surface of the locking claw 10 form a slight gap so that the locking claw 10 is separated from the rear surface 11 of the panel P.

Next, the operation of the temporary locking arm 6 in the process of mounting the electrical junction box A on the panel P will be described. First, as shown in FIGS. 3A and 3B, the temporary locking arm 6 for temporary locking provided in the electric connection box A is inserted into the temporary locking hole 9 of the panel P to loosen the locking claw 10. Temporarily fix by hooking.

Then, the fixing bolt 12 is inserted into the mounting hole 5 of the fixing bracket 3 on the upper right side of the upper case 1, and as shown in FIG. 4A, the panel P having the mounting hole 8 is opened. The nut 13 attached to the back surface 11 is screwed and fastened. In this state, as shown in FIG. 4B, the lower fixing bracket 3'of the upper case 1 and the panel P are not in close contact with each other.

Next, a fixing bolt 12 'is inserted into the mounting hole 5'of the lower fixing bracket 3', and the fixing bolt 12 'is inserted as shown in FIG.
As shown in (a), it is screwed and fastened to a nut 13 'attached to the rear surface 11 of the panel P having the mounting hole 8'opened.
At this time, since the fixing brackets 3 and 3'and the panel P come into close contact with each other, the temporary locking arm 6 deeply penetrates into the temporary fixing hole 9 of the panel P as shown in FIG. Is panel P
It is separated from the rear surface 11 by the extension 6a of the temporary locking arm 6 via a gap. Therefore, even when the electric connection box A is mounted on the vehicle body and subjected to vibrations during traveling, the locking claws 10 do not come into contact with the rear surface 11 of the panel P or the like.

[0013]

According to the present invention, since the temporary locking arm for temporarily locking the electric connection box to the counterpart panel or the like is provided with the locking claw via the extension portion, When the electric connection box is fixed to the side panel or the like, the locking claw is separated from the mating panel via the extension. Therefore, even if the electrical junction box receives vibrations such as when the vehicle is running, the locking claws come into contact with the mating panel, etc., and abnormal noise is generated, and the generation of fine pieces due to friction is reliably prevented. The durability and reliability of the box are significantly improved.
