摘要： PURPOSE:To manufacture a box body having sufficient strength and arbitrary dimensions easily by selecting a plurality of ceiling frames, floor frames, and column frames of different dimensions, bending each frame on the side thereof into L-shape or C-shape to form an abutting part, screwing the abutting part by means of bolts and nuts, and then fixing a door to the column frame at the end part. CONSTITUTION:Ceiling frames 1, 2 and floor frames 3, 4 of a plurality of types of dimensions are selected and a plurality of column frames 5-7 are planted therebetween. Each frame 1-7 is then bent, at the side end part thereof, into L-shape or C-shape to form abutting parts (1a), 1b, 3b, 3c, 5a, 5b, (6a) 6b, (7a) 7b. Coupling holes are made at the abutting parts corresponding each other which are them screwed by means of bolts and nuts. Right and left plate metals 9, 11 and a protective plate 10 are also fixed at required points. A door 14 reinforced by a reinforcing metal 15 is fixed to the column frame 5 on the end side. This structure allows easy manufacture of a box body having sufficient strength and arbitrary dimensions without requiring any special tool or welding.

摘要： PURPOSE:To provide planar miniaturized switches with fuses by providing insulating barriers between power side fixed contacts and power side clips, and arranging load switches and fuses on the right and left of the insulating barriers. CONSTITUTION:Insulating support plates 1 are provided with power side clips 13 and load side clips 14 fitting or removing fuses 6 and moving blades 8 contacted with or separated from power side fixed contacts with the rotary shafts connected to the power side clips 13 adjacent to the clips used as fulcrums. Intermediate connection sections 13A, 13B are connected to the power side clips 13 between the power side clips 13 and the load side clips 14 from the rotary shafts of the moving blades 8. Insulating barriers 3 are provided between the power side fixed contacts and the power side clips 13, and load switched 5 and fuses 6 are arranged on the right and left of the insulating barriers 3. Switches with fuses easy to fit can be obtained.
