ない。Next, the operation of the mounting guide section 12 will be described. The electronic board 2 is mounted on the holding wall 7 provided on the electrical junction box body 1.
In order to mount the electronic board 2, it is necessary to insert the electronic board 2 between the locking steps 8. However, as shown in FIG. 3, at the time of mounting work, the cover 3 is attached to the board mounting portion of the electrical junction box main body 1 in a state where the end 2 a of the electronic board 2 is slightly shifted and disposed on the introduction slope 7 b. 4b, the mounting guide 1
The front end 12a of the electronic substrate 2 presses the electronic substrate 2, and as shown in FIG. 4, the end 2a of the electronic substrate 2 descends along the introduction slope 7b and is inserted into the locking step 8. At this time, since the holding wall 7 and the electronic substrate 2 are appropriately elastically deformed, there is no problem in the insertion.

きる。As shown in FIG. 5, the position of the end 2a of the electronic substrate 2 is shifted from the introduction slope 7b to the top 7a of the holding wall 7.
a, the cover 12 is erroneously pressed to cover the cover 3, even if the cover 3 is pressed by mistake.
As a result, the end 2a of the electronic substrate 2 pressed against the top 7a of the holding wall 7 abuts and the electronic substrate 2 cannot be lowered.
Therefore, it becomes impossible to push the cover 3 in, so that the position of the electronic substrate 2 can be reliably found to be abnormal.

となるなどの多くの利点がある。According to the electric junction box of the present invention, since the mounting guide portion is protruded from the inner wall of the cover enclosing the electronic board, the mounting guide portion is used when the cover is mounted on the electric junction box body. The electronic substrate is pressed and can be easily mounted at a predetermined position. In particular, by providing the introduction slope on the holding wall that holds the electronic substrate, it becomes possible to mount the electronic substrate smoothly. Also, if the end of the electronic board is off the introduction slope, it will not be possible to cover the cover,
There are many advantages such that a state where the electronic board cannot be mounted can be reliably detected, and a failure due to incomplete mounting can be prevented beforehand.
