[Industrial applications]

 The present invention relates to a structure of a mounting portion of an electric connection box which can be easily mounted on a vehicle body.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, when attaching an electric junction box to a vehicle body, a bolt insertion hole 3 of a resin mounting portion 2 provided at an end of the electric junction box 1 and a button of an electric junction box supporting portion 9 of the vehicle body are mounted. The resin insertion part 2 of the electric junction box 1 is overlaid with the bolt insertion hole 10 and the bolt 4 is inserted into both of these overlapped insertion holes 3 and 10 and the tip of the bolt is tightened with the nut 11. It was done by the method.

[Problems to be solved by the device]

 However, both the inner diameter of the bolt insertion hole of the conventional electrical junction box mounting part and the inner diameter of the bolt insertion hole of the vehicle body electrical junction box support part as described above are larger than the outer diameter of the bolt. To do this, for example, hold the electrical junction box in your left hand and align the bolt insertion holes of this electrical junction box mounting part with the bolt insertion holes of the electrical junction box support part of the vehicle body with the electrical junction box mounting part facing down. With the right hand, insert the bolt from above into both of the above-mentioned through holes, and then tighten the nut with the right hand while holding the electrical connection box in the left hand. Was extremely bad.

[Means for solving the problem]

 The present invention has been made as a result of intensive studies in view of such circumstances, and an object of the present invention is to provide a mounting portion structure of an electric junction box which can be easily mounted on a vehicle body. That is, according to the present invention, the bolt of the resin mounting portion provided at the end of the electric connection box is inserted in the structure of the mounting portion of the electric connection box in which the electric connection box is attached to the electric connection box mounting support portion of the vehicle body by the bolt. The inner diameter of at least a portion of the hole is formed to be slightly smaller than the outer diameter of the bolt, and the bolt is press-fitted and fixed in the bolt insertion hole.

The electric junction box mounting portion structure of the present invention is such that a bolt is press-fitted and fixed in the bolt insertion hole of the electric junction box mounting portion, and the press-fitted and fixed bolt is inserted in the bolt of the electric junction box support portion of the vehicle body. By inserting the bolts through the holes, it is possible to eliminate the trouble of aligning the bolts when inserting the bolts into the insertion holes of the electric junction box mounting portion and the electric junction box support portion of the vehicle body. The method of press-fitting and fixing the bolts in the bolt insertion holes of the mounting part of the electrical junction box is to reduce the inner diameter of at least part of the bolt insertion holes of the electrical junction box mounting part to slightly smaller than the outer diameter of the bolt, By utilizing the fact that it is made of resin and has elasticity, the bolt is press-fitted and fixed in the portion of the insertion hole where the diameter is reduced. Therefore, it is preferable to set the bias between the inner diameter of the portion of the insertion hole having a slightly smaller diameter and the outer diameter of the bolt to be about 0.2 to 0.5 mm. If the bias is less than 0.2 mm, the bolt will be sufficiently stable and fixed. However, if it exceeds 0.5 mm, it becomes difficult to press the bolt into the small diameter portion. In the mounting portion structure of the present invention, the bolts can be press-fitted and fixed to the mounting portion of the electrical junction box, so there is no need to separately prepare the bolts, and parts management is easy. The electric junction box is usually manufactured by an injection molding method, and the main body portion and the mounting portion of the electric junction box are integrally made of resin.

[Action]

 In the electric junction box mounting portion structure of the present invention, the bolt for mounting the electric junction box on the vehicle body is press-fitted and fixed in the bolt insertion hole of the electric junction box mounting portion. It is possible to easily install the electric connection box on the vehicle body by omitting the work of overlapping the bolt insertion hole of and the bolt insertion hole of the electric connection box support portion of the vehicle body.

【Example】

 An embodiment of the electric junction box mounting portion structure of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the electric junction box mounting portion structure of the present invention. A mounting portion 2 is provided at an end of the electric junction box 1, and a bolt insertion hole 3 is formed in a central portion of the mounting portion 2. The bolt insertion hole 3 is formed in a shape in which the head 5 of the bolt 4 and the bolt base 6 are fitted together, and the inner diameter of the insertion hole 3 at the portion where the bolt base 6 is fitted is the same as that of the bolt base 6. The diameter is 0.3 mm smaller than the outer diameter. The bolt base 6 is press-fitted and fixed to the reduced-diameter portion 8. The bolt screw portion 7 projects from the insertion hole 3 of the electric junction box mounting portion 2. The protruding bolt screw portion 7 is passed through the bolt insertion hole 10 of the electric junction box support portion 9 of the vehicle body, and the tip of the bolt screw portion 7 is inserted. Tighten with nut 11 to fix.

2A and 2B are vertical cross-sectional views showing examples of the insertion hole shape of the electrical junction box mounting portion of the present invention. The insertion hole 3 formed in the mounting portion 2 of the electric junction box has a shape in which the head and the base of the bolt are inserted, and the diameter-reduced portion 8 is stepwise from the bolt head arrangement side 12 (Fig. A). Alternatively, it is formed in a taper shape (Fig. B) to be gradually narrowed, so that the tip of the bolt screw part can be easily inserted into the insertion hole. 3A and 3B are perspective views respectively showing an embodiment of a bolt constituting a mounting portion of the electric junction box of the present invention. The bolt 4 is composed of a head 5, a base 6 and a screw 7. The surface of the bolt base 6 which is located at the portion where the bolt insertion hole of the electric junction box mounting portion has a small diameter has a smooth surface as shown in FIG. The one shown in Fig. B is one in which the score line is formed in a twill shape so that it can be firmly fixed. The cross section of the bolt head 5 is square or hexagonal, and the head is inserted into a bolt insertion hole formed in the same shape so that the bolt does not rotate idly when tightening the nut.
