In an electronic control unit, a chassis is provided with a plate portion, and a circuit board is secured to a board-side attaching surface of the plate portion with a predetermined space secured relative to the plate portion. The chassis is further provided with a side wall protruding from the circumferential portion of the other surface of the plate portion and is mounted on a surface of a housing incorporating a device therein, with an end surface of the side wall being seated on the surface of the housing. A bus bar is fixed at a fixing portion thereof to the board-side attaching surface between the plate portion and the circuit board and is connected to a terminal of the device which is taken out from the housing. The bus bar is provided at plural free ends thereof with branch portions at which lead portions extend to be joined at end portions thereof to the circuit board. Elastic portions for reducing stresses which are developed at juncture portions of the lead portions to the circuit board as the temperature changes are formed between the base portion and the branch portions alongside the board-side attaching surface.

Electronic control unit

An electronic control unit case is disclosed, wherein a coil is provided on the top surface of a block housing control equipment for operating the same. The case protrudes a sidewall from the circumferential part of a plate portion thereof in which a bus bar is embeded and is secured onto the block with the sidewall resting at its end surface on the block while covering the coil. An electronic control unit is attached to the back surface of the plate portion, a through hole is formed in the plate portion in correspondence to the coil, and a terminal of the coil and a terminal portion of the bus bar are joined to each other in the through hole. In a plane which is parallel to the axis of the coil as well as to a plane in which a portion embeded in the plate portion of the bus bar extends, the terminal portion of the bus bar is bent twice or the terminal portion of the bus bar and the coil terminal are bent both once so that a point where the terminal portion of the bus bar and the coil terminal are joined to each other is offset from the portion embeded in the plate portion of the bus bar in a direction parallel to the coil axis or is further offset from a root portion of the coil terminal in the same direction as the portion embeded in the plate portion of the bus bar extends. Further, the through hole is formed to extend math a thin width in the same direction as said portion embeded in said plate portion of said bus bar extends.

Electronic control unit case

A first electronic control unit () provided with a printed circuit board () and a second electronic control unit (E) having pressure sensors () mounted therein can be assembled with each other. Intermediate connectors () are mounted in the first electronic control unit (), and terminal fittings () are accommodated therein. Each terminal fitting () is provided with a board-side connecting portion () to be soldered to the printed circuit board () and a resilient contact piece () to be resiliently brought into contact with a terminal portion () of the pressure sensor ().

Construction for connecting a circuit board and an electrical part, a brake oil pressure control unit

The invention is directed to an electromagnetic valve unit, which includes a housing for defining therein a first chamber and a second chamber separated by a wall member having at least a communication hole, and a plurality of electromagnetic valves each having at least a terminal. At least a part of each electromagnetic valve is mounted in the first chamber. A circuit board for mounting thereon an electronic control element for controlling the electromagnetic valves is mounted in the second chamber. The valve unit further includes a conductive member, one end portion of which is connected with each terminal of the electromagnetic valves, and the other end portion of which is connected with the circuit board through the communication hole of the wall member. And, a seal member such as a resilient grommet is provided for holding the conductive member in the communication hole of the wall member to provide a seal therebetween. Each of the electromagnetic valves may be provided with a valve portion and a solenoid coil portion which is separable from the valve portion and which has the terminal connected with the conductive member.
