An electrical junction box includes a body having an accommodation space, a first cover attached around a pivot shaft of the body to cover a part of the accommodation space, a second cover attached to the body to cover another part of the accommodation space and a conductor portion to transmit electric power. The first cover includes an interfering portion to move around the pivot shaft in accordance with pivoting of the first cover when the first cover is being opened or closed. The second cover includes an interfered portion to be arranged on a movement locus of the interfering portion when the second cover is closed, and not arranged on the movement locus when the second cover is opened. The conductor portion includes a portion arranged in the part of the accommodation space and to be isolated from the outside by the first cover.

Electrical junction box

An electrical connection box includes an insulating connection box housing and an insulating branch box housing. The insulating connection box housing stores a conductive connection box bus bar therein, and the insulating branch box housing stores a conductive branch box bus bar therein. The branch box housing and the connection box housing are stacked in a vertical direction. The connection box bus bar and the branch box bus bar are electrically connected by bringing connection box bus bar tip portions of the connection box bus bar into direct contact with branch box bus bar tip portions of the branch box bus bar and by jointly fastening the tip portions using bus bar fastening members.

Electrical connection box

An electrical connection box is provided with a conductive bus bar, an insulating housing body, a cover, and a power supply line. The cover opens or closes with respect to the housing body at a fully open position and a fully closed position. The housing body has a connector at a position exposed to the outside, with the connector configured so that a terminal provided at a tip of the power supply line is attachable or detachable to or from the connector. A restriction portion, which restricts the power supply line from moving in the longitudinal direction is provided in the cover. In the state where the terminal is connected to the connector, the tension is created on the power supply line in the longitudinal direction by the restriction portion during moving the cover from the fully closed position to the fully open position side.

A connection structure of an electrical junction box includes: a first housing which is fixed to a vehicle and in which a through hole is formed; and a terminal block that is inserted into the through hole, has a conductor, and is supported by the first housing, wherein the conductor includes a first terminal portion placed on one side of the through hole in a penetrating direction in which the through hole penetrates the first housing, and a second terminal portion that protrudes from the first housing toward the other side in the penetrating direction and that is connected to an electric wire.

Connection structure of electrical junction box

An electrical connection box includes a housing member, a first cover member, a second cover member, a hinge structure between the first and the second cover members, and a detachment prevention structure that disables detachment of the second cover member from the first cover member. The hinge structure includes a rotation shaft of the first cover member, a bearing of the second cover member, and a through hole in the first cover member. The through hole allows the bearing to be inserted from a free end and move in a direction that intersects an insertion direction of the bearing and is perpendicular to the axial direction of the rotation shaft to be fitted to the rotation shaft. The detachment prevention structure includes a rotational retaining section of the bearing and a retainer of the housing member.
