DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary fixing structure of 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 junction box is mounted on a mating structure such as a vehicle body of an automobile, it is fixed to the vehicle body by bolting. In this installation work, it may be necessary to mount the electric connection box in an inclined state, and it is necessary for the operator to manually tighten the bolts while supporting the electric connection box, which makes the work extremely difficult, and There is a problem that the performance is reduced.

In order to facilitate this mounting operation, Japanese Utility Model Laid-Open No. 4-47328 discloses FIGS.
As shown in (1), there has been proposed a temporary fixing structure of an electric connection box which can be attached to a mating panel while the electric connection box is temporarily fixed. In the temporary fixing structure of the electric connection box shown in FIG. 6, a hook piece b is protruded from the upper end of the electric connection box body a, and this hook piece b is brought into contact with the back side of the panel c as the mating structure. Thus, the tilting of the electric connection box main body a is temporarily prevented before the bolting of the mounting operation is performed.

[0004] However, after the electric connection box main body a is fixed by bolting, the hook piece b is located at a position where it comes into contact with a nut e for fastening a bolt d inserted through the panel c. There is a possibility that an abnormal noise is generated due to the vibration during the driving of the automobile, or the hooking piece b is shaved by friction to generate a fine piece, which may enter the electric junction box and cause a failure in the electric circuit. There is a problem that there is.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. The present invention can smoothly mount an electric junction box, and can be mounted on a vehicle body to receive vibration during traveling. In the event of friction,
An object of the present invention is to provide a temporary fixing structure of an electric junction box which is excellent in durability and reliability without generating fine pieces due to wear.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method for fixing an electric connection box to a mating structure by temporarily attaching the electric connection box to a temporary fixing hole provided in the mating structure. In a temporary fixing structure of an electric connection box in which a temporary fixing arm protruding from a box is engaged to temporarily lock the electric connection box to a mating structure, the temporary fixing arm extends to the temporary fixing arm. A locking claw is provided via a portion, and the locking claw is separated from the back surface of the mating structure when the electric connection box is fixed to the mating structure. It is preferable that the temporary locking arm is attached to a temporary fixing bracket provided on a case of the electric connection box (claim 2).

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a side view showing an electric connection box A according to an embodiment of the present invention, and a side sectional view of a panel P as a mating structure on which the electric connection box A is mounted. Electrical junction box A
Is formed by housing various electric components and their wirings inside the upper case 1 and the lower case 2, as shown in FIG.
Fixing brackets 3 and 3 'are attached to the upper right and lower sides of the upper case 1, respectively, and a temporary fixing bracket 4 is attached to the lower right.

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

The temporary locking arm 6 projects from the upper case 1 in a direction substantially perpendicular to the upper wall 1a of the upper case 1 toward the lower case 2.
A locking claw 10 is provided at its free end via the extension 6a. When the electrical junction box A is fixed to the panel P, the length of the extension 6a is
Is formed so as to form a slight gap with the inner surface of the panel P 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 attaching the electric junction box A to the panel P will be described. First, as shown in FIGS. 3A and 3B, the temporary fixing arm 6 of the electric connection box A is inserted into the temporary fixing hole 9 of the panel P, and the locking claw 10 is hooked, thereby temporarily fixing. Keep it.

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

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

[0013]

According to the present invention, since the locking claw is provided via the extension on the temporary locking arm for temporarily locking the electric connection box to the mating panel or the like, the locking claw is provided. When the electric connection box is fixed to the side panel or the like, the locking claw is isolated from the mating panel via the extension. Therefore, even if the electric connection box is subjected to vibration during driving of an automobile or the like, the locking claws come into contact with a mating panel or the like to generate abnormal noise and to reliably prevent the generation of fine pieces due to friction. The durability and reliability of the box are significantly improved.
