Electrical Junction Box

Abstract

To provide an electrical connection box having a good connection workability.SOLUTION: An electrical connection box includes a power supply-side electrical connection structure 70 which electrically and mutually connects a power supply-side electric wire WB outside a frame 40, an internal conductive member 60 inside the cylinder of a cylinder part 41, and a circuit branching component 20 outside the frame. The internal conductive member has a first electrical connection 61 and a second electrical connection 62 that physically and electrically connect an electronic component 10 inside the cylinder of the cylinder part. The circuit branching component has a power supply connection 22 and a load connection 23. The power supply side-electrical connection structure includes a male screw member 71 that protrudes a male screw part in a vehicle upward direction when mounted on a vehicle and a female screw member 73 screwed onto the male screw part. The male screw part is inserted into through holes TBa, 62a, 22a which are provided in a power supply-side terminal fitting TB of a terminal of the power supply-side electric wire, the second electrical connection of the internal conductive member, and the power supply connection of the circuit branching component, respectively, and the female screw member is screwed onto the male screw part, Thus, the power supply-side terminal fitting, the second connection of the internal conductive member, and the power supply connection of the circuit branching component are fastened together.SELECTED DRAWING: Figure 4
