BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case mounting structure used for fixing a case such as a fuse block or a relay block to a vehicle body panel or the like.

[0002]

2. Description of the Related Art A conventional case mounting structure is disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 63-34650. In such a structure, the insertion portion projects in a cantilever manner so as to protrude perpendicularly to the mating side mounting surface, so that an external force is easily input to the free end of the insertion portion during the case mounting and the case mounting, as well as during the case mounting. When a large moment acts on the portion, the insertion portion is extremely easily deformed by an external force.

The applicant of the present application has considered a case mounting structure shown in FIGS. In this case mounting structure, a case 5 is mounted via a bracket 3 to a vehicle body panel 1 in an engine room as a mating mounting surface. The bracket 3 has a bent section 7 at the upper and lower middle part, and is formed in a hook-shaped cross section as a whole. The lower part is a fixing part 9 and the upper part is a slide fitting part 11. The fixing part 9 is shown in FIG.
As described above, a predetermined gap S is formed between the slide fitting portion 11 and the vehicle body panel 1 by spot welding or the like. As shown in FIG. 5, the insertion portions 13a and 13b on both sides of the slide fitting portion 11 are bent so as to be offset toward the case 5. The upper ends of the insertion portions 13a and 13b are the slide insertion ends 1.
5a and 15b. A locking hole 1 for locking is provided at the center of the slide fitting portion 11 as positioning means.
7 are provided.

On the other hand, on the case 5 side, a pair of right and left slide fitting portions 19 to be fitted into the slide fitting portion 11 is extended in the vertical direction. This slide fitting portion 19
Open ends 21a and 21b to be inserted into the slide insertion ends 15a and 15b are opened at lower ends of the slide insertion ends 15a and 15b. Further, on the case 5 side, a movable lock arm 23 is provided between the slide fitting portions 19 as positioning means having elasticity with one end being free.
An engaging projection 25 as a positioning means is provided at the center of 3.

When mounting the case 5, first, the slide insertion ends 21a and 21b of the slide fitting portion 19 are opposed to the slide insertion ends 15a and 15b of the bracket 3, and the case 5 is moved downward as it is. . Then, the slide insertion ends 21a and 21b are inserted into the slide insertion ends 15a and 15b, and then the slide engagement portion 19 is entirely fitted into the slide engagement portion 11. At a predetermined position of this fitting, the engaging projection 25 of the movable lock arm 23 is locked in the locking hole 17 of the slide fitting portion 11 and is positioned relative to each other.

Therefore, even when various parts are densely packed and the mounting of the case 5 is limited to moving from above to below along the vehicle body panel 1, the case 5 can be easily mounted on the bracket 3. Things.

[0007]

However, the bracket 3 has the fixing portion 9 on the lower side and the slide fitting portion 11
Is extended upward through the bent portion 7, so that when the case 5 is inserted into the bracket 3 from above, the case 5
The slide fitting portion 11 of the bracket 3 is
An external force is likely to be applied to the tip, and a large moment acts on the bent portion 7 again, which may cause the bent portion 7 to be easily bent as shown in FIG. Further, even if the bracket 3 is not bent when the case 5 is mounted, the external force is applied to the already mounted case 5 when mounting other components around the case 5. The bracket 3 may be bent as shown in FIG. When the length of the bent portion 7 is increased to secure the gap S to some extent during the mounting operation of the case 5, the mounting operation of the case 5 can be performed efficiently. For this reason, there is a problem that the bracket 3 is more easily bent.

In view of the above, the present invention provides a case mounting structure capable of restricting the bending of the bracket when the case is mounted, securing a certain mounting space with respect to the mating mounting surface, and performing the mounting work efficiently. For the purpose of providing.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a case in which a pair of slide fitting portions are provided in a case, and a positioning engagement portion located between the slide fitting portions. A fixed portion and a slide fitting portion provided through a bent portion to the fixed portion, and the slide fitting portion has insertion portions on both sides capable of slidingly fitting the slide fitted portion. And a bracket provided with a positioning locking portion positioned between the two insertion portions and locking the engagement portion, wherein the fixing portion is fixed to a mating side, and the slide fitting portion has In a case mounting structure in which the slide fitting portion is inserted into an insertion portion and the engaging portion is locked by the locking portion to perform positioning, the slide fitting portion includes the bent portion with respect to the fixed portion. Is extended along the mating mounting surface via The width of the bent portion is formed to be smaller than the width of the slide fitting portion extending over the outer edge of the insertion portion, and the bent portion is arranged at the center in the width direction of the slide fitting portion, and the slide fitted portion is bent. The insertion portion is inserted into the insertion portion along the mating side mounting surface from the side of the portion.

[0010]

In the bracket 3, the fixed portion 9 has the slide fitting portion 11
And is fixed to the mating side mounting surface 1. The slide fitting portions 19 are attached to the slide insertion ends 15a, 15b formed on both sides of the upper end of the slide fitting portion 11 on the fixed portion side.
If the sliding insert ends 21a and 21b are opposed to each other and the case 5 is moved downward as it is, the slide insert ends 21a and 21b are firstly inserted into the slide insert ends 15a and 15b.
Then, the slide fitting portion 19 is entirely and slide-fitted into the slide fitting portion 11. At predetermined positions of the fitting, the positioning means 17 and 25 perform positioning between the slide fitted portion 19 and the slide fitted portion 11.

In this mounting operation, even if a force acts on the bracket 3 from the case 5, the slide fitting portion 11 is fixed to the fixing portion 9.
Since it is located below and is downward, the force acting on the bracket 3 from the case 5 directly acts on the bent portion.
Therefore, the moment acting on the bent portion itself is small, and the deformation of the bracket 3 can be suppressed. Also, even if an external force is applied to the case 5 after mounting, the deformation of the bracket 3 is similarly suppressed. In addition, for example, when a downward external force acts on the case 5, the slide fitting portion 11 is displaced in a direction approaching the mating mounting surface.
The movement is regulated, and the deformation is suppressed. Further, since the bracket 3 is hardly deformed, a certain mounting space between the slide fitting portion 11 and the mating side mounting surface 11 can be secured.

[0012]

Embodiments of the present invention will be described below.

FIGS. 1 to 3 relate to an embodiment of the present invention, and the same components as those of the above embodiment are denoted by the same reference numerals, and redundant description will be omitted.

First, FIG. 1 is a perspective view showing a relationship between the case 5 and the bracket 3 before fitting, FIG. 2 is a perspective view showing a state after fitting, and FIG. It is sectional drawing which shows the state after joining.

The engaging projection 25 as the engaging portion of the movable lock arm 23 is locked in the locking hole 17 as the locking portion, and the slide fitting portion 19 is positioned with respect to the slide fitting portion 11.

As described above, since the slide fitting portion 11 is mounted downward, even if a relatively large force is applied to the bracket 3 when the case 5 is mounted, the deformation of the bracket 3 is regulated, and the case 5 can be correctly mounted. .
Also, after the case 5 is mounted, even if external force acts on the case 5 when mounting other components around the case 5, the deformation of the bracket 3 is similarly restricted, and the case 5 is maintained in a properly mounted state. I can do it. In addition, due to the structure of the bracket 3 that is not easily deformed, the gap S serving as a mounting space between the slide fitting portion 11 and the vehicle body panel 1 can be increased to some extent as shown in FIG. Efficiency can be significantly improved.

FIG. 4 relates to another embodiment. The same components as those in the above embodiment are denoted by the same reference numerals and described.

a and 13b are flat surfaces without offset. The fixing portion 9 has a structure that is fixed to the vehicle body panel 1 by bolts 27. The case 5 can be attached to the bracket 3 thus fixed by the same operation as described above. Therefore, in addition to having substantially the same operation and effect as the above-described embodiment, if the mounting position of the bolt 27 is changed, the gap S can be changed, and it is possible to cope with various working modes.

[0019]

As is apparent from the above description, according to the structure of the present invention, the slide-fitted portion on the case side is aligned with the bent portion of the slide-fitted portion, and the slide-fit portion is inserted as it is and slide-fitted from the bent portion side. As a result, the moment acting on the bent portion due to external force during or after work can be reduced, and deformation of the bracket can be suppressed. In addition, it is possible to secure a certain gap between the slide fitting portion and the mating side mounting surface, and it is possible to remarkably increase the work efficiency. In addition, when inserting, the insertion can be performed while performing positioning with the bent portion having a width smaller than the width of the slide fitting portion including the outer edge of the insertion portion as a guide, and the insertion of the slide fitting portion into the slide fitting portion can be performed. It becomes very easy.
