Abstract: Rib portions (87) have first rib portions (87a) which abut against outer portions, and second rib portions (87h) which abut against wail portions. They are formed in plural numbers over the entire circumference of an edge portion (82). Pressing portions (88) are disposed on a lid portion (81) so as to be opposed to a relay (2), and, in a state where engaging portions (67) and engaged portions (84) are engaged with each other, elastically deformed to press the relay (2) toward a bottom portion (61).

Abstract: A battery pack controller is provided having electric wires of the main wiring lines of a precharge circuit laid on the front surface of a base plate. LA terminals (i.e., ring terminals) connected to the electric wires are clamped by screws and the main-circuit bus bars to the relay terminal portions of a main relay mounted on the rear surface. Further, each of the LA terminals (i.e., ring terminals) has a wing portion protruding beyond the protuberant height of an electric-wire connection portion. An electric wire is bent and disposed to extend from the front surface side of the base plate toward the relay terminal portion, a terminal accommodation portion in which the LA terminals (i.e., ring terminals) are accommodated is provided at a part extending from the electric-wire bent portion to the relay terminal portion, and bottom grooves are formed in the terminal accommodation portion into which the wing portions are inserted.

Abstract: Provided is a wire holding structure including: a wire; a member, on which the wire is arranged in an arranging direction, and which includes an arranging surface on which the wire is arranged and at least one pair of standing surfaces including a first standing surface and a second surface respectively opposing both sides of the wire; and at least three protrusions including a first protrusion, a second protrusion and a third protrusion, the first and third protrusions protruding from the first standing surface and the second protrusion protruding from the second standing surface.

Abstract: An wire holding structure includes a member and a pair of protrusions. The member includes an arranging surface on which the wire is arranged and at least one pair of standing surfaces respectively opposing both sides of the wire. The protrusions are protruded from the standing surfaces respectively opposing the both sides of the wire. The protrusions are disposed at positions which are shifted each other in the arranging direction, so that a gap between the protrusions is larger than a diameter of the wire and a gap between tips of the protrusions projected in the arranging direction is smaller than the diameter of the wire. A distance between the arranging surface and the protrusions is larger than the diameter of the wire.

Abstract: The assemblability of LA terminals with electric wires is improved. The electric wires of the main wiring lines of a precharge circuit are laid on the front surface of a base plate, LA terminals connected to the electric wires are clamped to the relay terminal portions of a main relay mounted on the rear surface, by screws together with main-circuit bus bars, each of the LA terminals has a wing portion protruded beyond the protuberant height of an electric-wire connection portion, an electric wire is bent and disposed to extend from the front surface side of the base plate toward the relay terminal portion, a terminal accommodation portion in which the LA terminals are accommodated is provided at a part extending from the electric-wire bent portion to the relay terminal portion, and bottomed grooves into which the wing portions are inserted are formed in the terminal accommodation portion.

Abstract: An electric connection box which can easily attach electric components to an attachment portion of box body. The electric connection box includes a box body having the attachment portion attaching the relay on an upper surface of the box body, and a relay fixed on the box body. The attachment portion includes a tube, a plurality of openings and a plurality of holding portions arranged in the opening. The tube inserts the relay into an inside thereof, and stands from the upper surface. The opening passes through the tube 5, and is arranged with a space along a circumferential direction of the tube. The holding portion presses the relay toward the inside of the tube, and holds the relay to the tube. The holding portion includes an arm and a protrusion projecting toward the inside of the tube.
