When the connecting assembly on the side plate 210 is inserted into the connecting assembly on the side plate 310 from top to bottom, the buckle a23 pushes the side plate 310 outwards through the lower end of the second inclined surface, and meanwhile, the buckle a33 pushes the side plate 210 outwards through the lower end of the second inclined surface, so that the side plate 210 and the side plate 310 are more tightly meshed and are not loosened in the vertical direction, and finally, the mini fuse box 200 and the micro fuse box 300 are firmly connected and are not easily loosened.

It should be noted that the connection between the fuse boxes of the present invention may be the interconnection between the fuse boxes of the same type, or the interconnection between the fuse boxes of different types; can be interconnect between two fuse boxes, also can be interconnect between the fuse box more than two, the utility model discloses do not do the restriction to the type of the fuse box that connects and fuse box quantity of every type, can set up according to actual need.

While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
