BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a box for storing electric equipment which has a branch base for mounting electric equipment therein and which is used for a distribution board or the like.

[0002]

2. Description of the Related Art In a conventional electrical equipment storage box used for a distribution board or the like, as shown in FIG. 6, a branch base 51 for mounting a circuit breaker for branching, a terminal block, etc.
Rails 54 attached to both sides of the back plate portion 53 of the box body 52,
It was common to fix the migration bases 55, 55 between 54 with screws 56. However, in such a conventional one, there is a problem that it takes a long time to assemble because the branch base 51 is screwed at four places or two places. In addition, there is a possibility that the screw may be loosened, so that the structure has a low reliability.

[0003]

The present invention has been completed in order to solve the above problems of the prior art and to provide a box for storing electrical equipment which is easy to assemble and has a high reliability as a structure. is there.

[0004]

[Means for Solving the Problems] The above-mentioned problem is that two crossing bases having long holes parallel to these rails are installed between two rails fixed to the box body, and both end portions of the leg plate portion are installed. It is possible to solve the problem by an electric equipment storage box characterized in that a branch base having outward projections is attached to each of the crossover bases by fitting each projection into a long hole of the crossover base. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to illustrated embodiments. In FIG. 1, reference numeral 1 denotes a box body, and rails 3 for attaching a base and the like are attached to both sides of a back plate portion 2 of the box body 1. Reference numerals 4 and 4 denote two transition bases in which long holes 5 parallel to the rails 3 are arranged in parallel at a required interval. The two transition bases 4 and 4 are intermediate portions of the rails 3 and 3, and Both sides are fixed by screws on the bottom

Reference numeral 6 is a branch base to which a circuit breaker for branching, a terminal block and the like are attached. As shown in FIG. 3, the branch base 6 is provided on both sides of the attachment plate body 7 with the leg plates 8 and 8 facing backwards.
Are formed continuously, support end surfaces 9 and 9 are formed inside and below the tip surfaces of the leg plate portions 8 and 8, and outward projections 10 and 10 are formed at both outer ends of the upper and lower support end surfaces 9 and 9. It was formed.

As shown in FIGS. 2 and 3, these branch bases 6 are fitted with the respective projections 10 in the long holes 5 of the transition bases 4 and 4, and the support end face 9 is brought into contact with the surface of the transition base 4. It is attached in contact. Further, in the embodiment, the long hole 5 is vertically symmetrical so that the crossover base 4 can accommodate both the upward and downward protrusions 10, 10. Further, each long hole 5 is enlarged on both sides of the central portion so that the fitting work of the protrusion 10 can be facilitated.

When the branch base 6 is long, a supporting end surface 9 and a protrusion 10 may be provided in the middle of the leg plate portion 8 as shown in FIG. .

[0009]

In order to attach the branch base 6 thus constructed to the crossover base 4, for example, both sides of one crossover base 4 are attached to the rails 3 and 3 with screws 11, and then one protrusion 10 of the branch base 6 is attached. Are fitted into the long holes 5 provided side by side on the crossover base 4. Then, the other protrusion 10 of the other branch base 6 is fitted into the long hole 5 of the other crossover base 4, and both sides of this crossover base 4 are attached and fixed to the rails 3 and 3 with screws 11. Good. Since no screws are used to attach the branch base 6 and the transition base 4 in this manner, it is possible to reduce the number of screw fastening points and improve the efficiency of the assembly work.

The upper and lower transition bases 4, 4
The rails 3 and 3 may be attached to the rails 3 and 3 after the upward and downward protrusions 10 and 10 of the branch base 6 are fitted into the long holes 5 and 5 of both transition bases 4 and 4. Further, since the branch base 6 does not need to be bent to form a mounting margin for screwing at the tip of the leg plate portion 8, there is also an advantage that the mounting plate main body can be widened. Further, after the upper and lower transition bases 4 and 4 are attached to the rails 3 and 3, the branch base 6 is not likely to come off.

[0011]

As described above, according to the present invention, the branch base is attached to the crossover base by fitting the projection into the long hole, so that the screwing work can be reduced.
There is an advantage that the assembly work efficiency can be improved and a large device mounting area can be secured. Further, according to the present invention, the branch base is not likely to come off after the transition base is attached, and since the screws are not used for attaching the branch base to the transition base, there is no fear of loosening the screw, and the structure is The reliability of the body can be improved. Therefore, the present invention has an extremely great practical value as it eliminates the conventional problems.
