NOVELTY - The current collection box (10) has cover body (22) arranged to cover an opening of a housing. A first coupling portion (20) is formed on side surface of housing. A second coupling portion (24) is formed protruding by inner surface of cover body in a position opposing first coupling portion. An inner cover (25) has a notch penetrating second coupling portion and formed in a position corresponding to second coupling portion. An inner cover part (30) is formed in the notch of inner cover. The first coupling portion in inner cover part is located opposite second coupling portion of cover body.    USE - Current collection box used in collecting electric power from power supplies e.g. solar cells.    ADVANTAGE - Ensures improved safety and reduced risk of failure of electronic component since a user does not receive an electric shock, and is prevented from touching an electronic component when manually operating the opening and closing switch. Ensures easy operation and assembly since a screw or a bolt are used to couple the housing and cover body of the current collection box. Prevents the coupling components from being lost since the coupling components can be set without being removed from the current collection box. Prevents formation of a gap between the cover body and housing since the notch opening for allowing passage through the coupling part formed in the inner cover portion is blocked by the first coupling portion and coupling component formed in the cover body. Ensures easy manual detachment or attachment of the coupling component without using a special tool or technique. Ensures easy operation of the current collection box such that the current collection box interrupts electricity supply during an emergency, e.g. earthquake, fire. Ensures reduced material cost and manufacturing cost of the current collection box due to the use of metal and resin in respectively making the inner cover and cover body of the current collection box.    DETAILED DESCRIPTION - The housing is provided with an opening and closing switch (15) which can be operated with an input terminal and an output terminal, and which can be operated by manual control. An opening (28) is formed between the cover body and housing, and opposite the operation part (16) of the opening and closing switch. The inner cover part has a side wall formed except for the open end part and bottom face.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the current collection box.
