Abstract:
An electronic control unit includes a circuit board, a case, and a group of a plurality of bus bars fixed to the case by insert molding. The bus bars each include a terminal portion having a constant-width portion, and a base portion which is wider than the constant-width portion. The base portions of the respective bus bars are arranged parallel to each other in the width direction thereof. Each bus bar is bent at a bent portion of its base portion. The terminal portion of each bus bar extends through the circuit board and is soldered to and electrically connected to a terminal connecting portion of an electrical circuit on the circuit board at a soldered portion. The bent portions of alternate bus bars are offset from the bent portions of the other bus bars in the longitudinal direction of the bus bars, whereby the soldered portions of the respective terminal portions are arranged in a staggered manner.

The waterproof cover includes a first waterproof wall for covering a space above adjacent terminal metals, a second waterproof front wall and second waterproof side walls for partitioning a space between the adjacent terminal metals and a side wall of the casing.
Abstract:
A junction box has a casing assembly including an upper casing and a lower casing, a laminated unit including bus bars and insulation plates, and first and second printed circuit boards contained in the casing assembly. The first printed circuit board is used as a higher current circuit having thick-film conductors. The second printed circuit board is used as a middle or lower current circuit having thin-film conductors with thicknesses smaller than those of the thick-film conductors on the first printed circuit board. Board relays are mounted on a part of different peripheral portions on both sides of the first printed circuit board or a part of peripheral portion of either side of the first printed circuit board. The board relays are disposed in the casing assembly to be opposed to a first heat generating element containing space defined between a front side of the first printed circuit board and an inner surface of a top wall of the upper casing, and a second heat generating element containing space defined between a rear side of the first printed circuit board and an inner surface of a bottom wall of the lower casing.
Abstract:
A wire harness leading-out opening is provided at a junction between an electric connection box and a bottom surface cover which constitute an electric connection box. A cylindrical wire harness leading-out guide is provided on the periphery of the wire harness leading-out opening, and is formed in a way that the both circumferential ends of a half-cylindrical body formed on the electric connection box and a half-cylindrical body formed on the bottom surface cover are coupled to each other. In the inner circumference of a circumferential junction between the peripheral walls of the two half-cylindrical bodies, a concave portion is provided to accommodate a loose portion of an armoring member wrapped around the outer circumference of the wire harness.
Abstract:
One aspect of the present invention can include an electric connection box having a circuit board, a case inside of which said circuit board is housed, a plurality of fitting depressions capable of being fitted with an external electrical component, positioned on a side wall of the case opposing a board surface of the circuit board. Further, an air path inside of said case is defined by the plurality of fitting depressions positioned as an arrayed side by side with a spacing in between, and the air path circulates the air up and down between the plurality of fitting depressions, and an inlet positioned in the case and in communication with the air path, an exhaust outlet is positioned in the case in communication with the air path and positioned above said inlet, and a heat generating component is positioned in the air path.
Abstract:
An electrical junction box includes a box main body and a wiring block. The box main body includes a cassette block. The wiring block includes a first bus bar, a second bus bar, and a fuse. Each bus bar includes an electric parts connecting part and the power source connecting part. The electric parts connecting part is connected to electric parts attached to the cassette block. The power source connecting part includes a fuse connecting piece and a connecting piece. A terminal fitting connected to a power source is connected to the connecting piece. The fuse connects the fuse connecting pieces of the bus bars.
Abstract:
Three printed boards are stored in a case, and a relay connector for connecting the three printed boards is mounted on the second printed board at the middle position. The relay connector is provided with a first terminal storing part, which is long in a vertical direction, and a short second terminal storing part. The relay connector connects a terminal pin of the first printed board at an upper position with a terminal pin of the third printed board at a lower position, via a long first relay terminal stored in the first terminal storing part, while connecting a terminal pin of the first printed board and/or the terminal pin of the third printed board with a conductor of the second printed board, via a short second relay terminal stored in the second terminal storing part.
Abstract:
Providing an electric junction box, which can reduce a cost and the weight with maintaining shield effect, in the electric junction box including an electric unit and a shield case, a panel joint at a panel joining area of a conductive panel is formed with synthetic resin. The shield case can be formed with a thin sheet metal by press forming. The electric unit is received in the shield case, so that the electric junction box can maintain shield effect.
Abstract:
In a heat radiator plate, a mounting bracket extending from a peripheral edge portion of the heat radiator plate, an auxiliary heat radiator plate portion extending along the mounting bracket and positioned between the mounting bracket 39 and a body through a gap and a radiant heat radiator portion formed on a top end of the auxiliary heat radiator plate portion and opposing to the body through the gap are provided. Heat generated by a circuit construction body is conducted from the heat radiator plate, the auxiliary heat radiator plate portion and the radiant heat radiator portion to the gap and radiated to the body through the gap. The heat radiation characteristics of the connector box are improved.
