Description

[Detailed description of the invention] (Industrial application field) The present invention is an electrical component box (hereinafter simply referred to as a box) that accommodates electrical components such as relays and fuses, and is used in a bracket attached to the body of an automobile, etc. Regarding the structure to be assembled into.

(Prior Art) Conventionally, as a structure for assembling the above-mentioned box to the body of an automobile, for example, the structure shown in FIG. 3 is known.

That is, in the figure, 1 is a box in which electrical parts such as relays and fuses are housed, 2 is a bracket attached to a body such as a vehicle body (not shown), and box 1 is a flange portion 1b extending from the back plate 1a. It is fixed to the bracket 2 by inserting the protruding clip 3 into the fixing hole 4 provided in the bracket 2, and if necessary, a bolt or nut ( After inserting the bolt 5 into the hole 6 provided in another flange 1c extending from the back plate 1a of the box 1, tighten a nut or bolt (nut in the case shown) 7 to the bolt 5. It is a structure that can be assembled to the body.

(Problem that the invention aims to solve) However, the box 1 is usually installed in a narrow space in the car body, and the installation is done blindly by groping, so the clip 3 does not fit into the fixing hole 4. If it is inserted in a half-fitted state, or if multiple clips 3 are inserted into box 1 (usually 2)
When a plurality of fixing holes 4 provided in the bracket 2 are fitted into each of the fixing holes 4, even if a portion of the fitting between the clip 3 and the fixing holes 4 is partially missing, it may not be noticed. In such a case, there are problems in that the box 1 vibrates due to vibrations when the vehicle is moving, causing breakage of the box 1, circuit breakage due to falling of internal electrical parts, and generation of noise due to chattering.

The present invention was developed by focusing on the problems of conventional box mounting structures, and aims to provide an assembly structure that can securely and efficiently fix a box to a bracket attached to a body even when working blindly. shall be.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a pair of locking parts protruding from the back plate of a box to a pair of fixing parts of a bracket attached to the body of a vehicle, etc. In the assembly structure, a guide piece having a convex portion is provided protruding from the back plate of the electrical component box between the pair of locking parts, and the guide piece is fitted to the bracket. A structure is adopted in which a slide engaging portion is provided with a recessed portion corresponding to a convex portion of the slide engaging portion.

(Function) When assembling the box, by sliding the guide piece by engaging its convex portion with the concave portion of the bracket, the pair of locking portions and the fixed portion of the bracket are positioned, and the pair of locking portions are positioned. The stop part is easily and reliably fitted into the fixing part.

(Example) The present invention will be described in detail below based on the accompanying drawings.

FIG. 1 shows an embodiment of the box assembly structure according to the present invention in a partially cutaway perspective view before assembly.

Note that the same parts as in the conventional assembly structure shown in FIG. 3 will be designated using the same reference numerals.

In the figure, the assembly structure of the present invention is an assembly structure in which a box 1 is fixed to a bracket 2 attached to a body such as a vehicle.
The box 1 is fixed to the bracket 2 by having a guide piece 8 protruding from the bracket 2 and a locking part 9 provided on the bracket 2 so that the guide piece 8 is fitted into the engaging part 9.

In the above configuration, the back plate 1a of the box 1
A clip 3 as a locking portion having a locking piece 3a is provided on the flange portion 1b extending from the flange portion 1b, and
A hole 6 is provided in the other extended flange portion 1c of the back plate 1a as necessary, and a fixing hole 4 as a fixing portion into which the clip 3 is fitted is provided in the bracket 2. Hole 6 in the body (not shown)
It is similar to the conventional assembly structure in that the bolt 5 inserted through the box is fixed, but in the present invention, the guide piece 8 is attached to the back plate 1a of the box 1 (including its extended flange portion 1b). A protruding engaging portion 9 is provided on the bracket 2 to which the guide piece 8 is fitted and locked.

The guide piece 8 and the engaging part 9 may have any shape as long as they can easily guide the box 1 to a predetermined fixed position of the bracket 2 even when working blindly. In the embodiment shown in FIG. is constituted by a plate bent into a cross-sectional shape having a convex portion 8a, and the engaging portion 9 is formed by bending the convex portion 8a of the guide piece 8.
It has a recess 9a into which it is fitted.

Further, in the embodiment shown in FIG. 2, the guide piece 8' is constituted by a plate bent into a cross-sectional shape having a recess 8a', and the engaging part 9' provided on the bracket 2 fits into the recess of the guide piece 8'. Convex portion 9 into which 8a' can fit
It has a′.

Also, the mounting position of the guide pieces 8, 8' with respect to the box 1 and the engaging portions 9, 9' with respect to the bracket 2.
The forming positions of the boxes 1 and 2 are respectively set at positions corresponding to predetermined fixed positions of the bracket 2.

The operation of the assembly structure of the present invention will be explained below with reference to the embodiment shown in FIG.

First, the convex portion of the guide piece protruding from the box 1 is engaged with the concave portion of the bracket from below, and the bracket is pushed in the clip fitting direction. This work can be done blindly (by hand).
By this operation, the clip 3 protruding from the flange portion 1b of the box 1 is attached to the bracket 2.
They are guided via guide pieces 8 so as to accurately oppose the predetermined positions of the fixing holes 4 provided in the respective fixing holes 4 .

Then, when the box 1 is further pressed against the bracket 2, the locking piece 3a of the clip 3 locks into the fixing hole 4.
The box 1 is fixed to the bracket 2 by being fitted and locked to the bracket 2. In this case, by providing at least two clips 3 and at least two fixing holes 4, the box 1 can be sufficiently fixed to the bracket 2, but if necessary, as in the case of the conventional structure, bolts 5 fixed to the body (not shown) can be attached. By inserting the nut 7 through the hole 6 provided in the flange 1c of the box 1 and screwing the nut 7 onto the bolt 5, the box 1 can be fixed even more firmly. In this case, the guide piece 8 also acts as a guide for positioning the through hole 6 of the bolt 5 to face it.

In addition, by setting the fit play between the convex part 8a of the guide piece 8 and the concave part 9a of the bracket 2 to be smaller, each clip 3 can be attached to each fixing hole 4.
This allows for a more secure fit.

(Effects of the invention) Since the assembly structure of the box of the present invention is as explained in detail above, the pair of clips 3 provided on the box 1 are inserted into the predetermined fixing holes 4 provided on the bracket 2 with the guide pieces. 8 and the engaging portion 9 are automatically guided, so that it can be securely and easily fixed even in a blind operation, and the advantage is that the workability of assembling to the body can be greatly improved. Furthermore, the problem that only one of the pair of clips does not fit is eliminated, and damage to the box and generation of abnormal noise due to vibrations when the vehicle is running is prevented.
