Unlike the branch handle 5 a, the main handle 4 a protrudes from the outer surface of the main body cover 3. For this reason, the main handle cover 11 is also designed to protrude from the main body cover 3. By comprising in this way, the depth size of places, such as the branch switch 5 in the distribution board 1, can be minimized, and the location which protrudes can be only the 1st opening window 3a vicinity.

  Depending on the application of the distribution board 1, the distribution board 1 may not be provided with the main switch 4. Even in such a case, the main body cover 3 and the main handle cover 11 can be used. Alternatively, a cover having a small protrusion size outward from the main handle cover 11 can be used instead of the main handle cover 11.

  In a state in which the main handle cover 11 is attached to the main body cover 3, the lower projection 11f of the main handle cover 11 enters the first opening window 3a and contacts the lower window wall of the first opening window 3a. Yes. Similarly, the protrusion 11e on the upper portion of the main handle cover 11 enters the first opening window 3a and is in contact with the upper window wall of the first opening window 3a. The protrusions 11e and 11f regulate the position of the main handle cover 11 in the vertical direction. Thus, even when an impact or the like is applied to the main handle cover 11, the protrusion 11f (or the protrusion 11e) is applied to the lower (or upper) window wall of the first opening window 3a. Dropout can be prevented. The protrusions 11e and 11f may have an inclined surface that matches the inclination of the upper or lower window wall of the first opening window 3a. In addition, when the main handle cover 11 is attached upside down, the protrusion 11e is similarly hung on the lower window wall of the first opening window 3a.

FIG. 5B shows a left front perspective view in which the first opening window 3a, the main switch 4 and the main handle 4a are enlarged in the distribution board 1. FIG. Of the four window walls surrounding the first opening window 3a, the third engagement that engages with the first engagement portion 31 on both the first window wall 38a on the right side and the second window wall 38b on the left side. A joining portion 36 and two fourth engaging portions 37 that engage with the second engaging portion 32 are provided. The first window wall 38a and the second window wall 38b provided on the main body cover 3 face each other through the first opening window 3a. The third engagement portion 36 is a recess (notch) that can be engaged with the thin plate-like first engagement portion 31. The fourth engagement portion 37 is a recess (notch) that can be engaged with the cylindrical second engagement portion 32. Further, the third engaging portion 36 and the fourth engaging portion 37 are located at positions corresponding to the first engaging portion 31 and the second engaging portion 32, respectively, when the main handle cover 11 is attached to the main body cover 3. Provided.

  In addition, the shape, the number, and the arrangement of the third engagement portion 36 and the fourth engagement portion 37 are arbitrary, and according to the shape, the number, and the arrangement of the first engagement portion 31 and the second engagement portion 32, Each can be designed. For example, the third engagement portion 36 may be provided only on the first window wall 38a, and the fourth engagement portion 37 may be provided only on the second window wall 38b. Moreover, the uneven | corrugated relationship of a 1st-4th engaging part may be reverse to said example. Further, the third engaging portion 36 and the fourth engaging portion 37 may be provided on the upper and lower window walls of the first opening window 3a. In this case, the first engagement portion 31 and the second engagement portion 32 are provided on either the side surface 11a or the side surface 11b of the main handle cover 11, respectively. Further, when the shape of the first opening window 3a and the main handle cover 11 in a plan view is a square, the third engagement portion 36 and the fourth engagement portion 37 are provided on all the window walls of the first opening window 3a. May be.
