Abstract: An electronic device includes an integrated connector, a printed circuit board (PCB), a case, and a cover. The integrated connector has a connector pin having a first end and a second end. The first end of the connector pin is soldered to the PCB and the second end is arranged so that it is exposed to the outside of the case via a through hole. The second end is loosely fitted to the case so that it is movable in the axial direction. Stresses are less likely to occur in the connector pin even when components of the electronic device expand or contract.

Abstract: In an electronic circuit unit having more than two electric connectors, at least one of the connectors gets to have a group of connector pins, penetration-type connector housing, which the group of connector pins can be passed through with clearances, a plate to support the connector pins. This connector can be installed in the printed wiring board easily. Especially, when the electronic circuit unit has many electric connectors and some connectors are the above type, they can be installed in the printed wiring board easily and securely at the same time.

Abstract: An electronic control device includes first and second ceramic substrates housed in a case. The first ceramic substrate has electronic components including a semiconductor component mounted on its surface. The second ceramic substrate is fixed to the top face of the semiconductor component. The second ceramic substrate has electronic components mounted on its bottom surface. A connecting member having wiring members is arranged between the first and the second ceramic substrates. The first ceramic substrate is electrically connected with the second ceramic substrate via the wiring members.

Abstract: The bonding area of an outer contact terminal of a connector and the bonding area of an inner contact terminal are rectangular and different in width. The bonding area of the outer terminal is wider than that of the inner terminal. A single aluminum wire is used for connecting the bonding area of the inner terminal to a substrate, and two aluminum wires are used for connecting the bonding area of the outer terminal to the substrate. The outer terminals generate more heat and are located near the periphery of the connector to facilitate heat removal.
