Abstract: A holding portion in which a power supply distribution unit is inserted and held is formed in a case of an electrical connection structure. Here, the power supply distribution unit includes a main body formed so as to have an approximately twice-rotation symmetrical shape with respect to an imaginary line extending in a first direction. A projection is formed on the main body and/or the holding portion, and a groove into which the projection is inserted, and a restriction wall which interferes with the projection when the power source distribution unit is inversely inserted are formed on the holding portion and/or the main body. Further, a projection side inclined surface capable of guiding the projection into the groove by coming into contact with the restriction wall when the power source distribution unit is inserted in a state of a normal position is formed in the projection.

Abstract: There is provided a method for manufacturing an electric junction box that includes: a first bus bar and a second bus bar having one shape selected from a plurality of types of shapes; a housing that accommodates the first bus bar and the second bus bar; and a plurality of input and output portions to which a terminal connected to an external power supply is connectable. The manufacturing method includes: a first operation of providing the first bus bar and the second bus bar that have one of predetermined shapes selected based on a specification of the electric junction box; and a second operation of accommodating the first bus bar and the second bus bar provided by the first operation in the housing.

Abstract: An electrical connection structure includes: a base unit; and a battery circuit bus bar which is detachably mounted to a battery connection terminal provided in the base unit. Further, the base unit includes: the battery connection terminal; a power source distribution circuit component constituting part of a power source distribution circuit; and one case in which the power source distribution circuit component and the battery connection terminal are held. The battery circuit bus bar includes: a normal bus bar without a relief terminal; and a relief terminal-provided bus bar having the relief terminal. At least one of the normal bus bar and the relief terminal-provided bus bar is selectively mounted to the battery connection terminal.

Abstract: There is provided an electric junction box unit including: an electric junction box having a plurality of stud bolts; a plurality of electric wire with terminals each including a terminal and an electric wire and fastened to a corresponding one of the plurality of stud bolts; and a cover to which at least one of the plurality of electric wire with terminals is assembled. The electric junction box includes an interference portion that interferes with at least a part of the cover when the electric wire with terminals assembled to the cover are disposed at a position different from a normal position where one of the electric wire with terminals is fastened to the corresponding stud bolt.
