An integrated circuit for a vehicle, vehicle which is formed in the shape of a case and which includes a pair of circuit boards, and a connector electrically connected to another connector. Each circuit board includes a metal circuit board main body, defining an outer portion of the case, an insulating layer formed on the entire inner surface of the circuit board main body, a conductive layer formed on the insulating layer in a predetermined circuit pattern, and a plurality of circuit elements electrically connected to a predetermined portion of the conductive layer. The connector includes a connector housing fixed to the circuit boards and having a recess for receiving the other connector, a plurality of through holes being formed in the connector housing, and a plurality of connector pins, one-end portions of which are connected to connecting terminals formed at an edge portion of the conductive layer, middle portions of which extend through the through holes formed in the connector housing, and the other-end portions of which project into the recess and are contactable with the other connector.

Integrated circuit for vehicle

An integrated circuit of this application includes a circuit board in which a conductive layer of a desired pattern is formed on a metal substrate through an insulating layer, a circuit element mounted on the insulating layer, and first and second connectors for connecting at least the circuit element and an external device. The circuit element is nondetachably mounted on the insulating layer, and has a nonvolatile content which can be rewritten by an external operation. The first connector connects at least the circuit element to a portion to be controlled, and the second connector connects the circuit element and an external processing device via a path different from that of the first connector so as to process a storage content of the circuit element.

Integrated circuit having metal substrate

In a vehicle control unit structure, a pair of first and second circuit boards in each of which conductive layers are adhered on a metal substrate through an insulating layer, and a circuit element is fixed to each of the conductive layers are arranged so that the conductive layers are connected to each other through a connecting substrate and are arranged to oppose each other. A third circuit board is located between the first and second circuit boards. The foregoing vehicle control unit structure is arranged into a closed case-like shape, thus preventing dust contamination and direct access by an operator and achieving a low cost, compact unit. A circuit element is mounted on the third circuit board.

Vehicle control unit structure

In a connector structure for a hybrid integrated circuit, two hybrid integrated circuit boards each include a conductive layer having a predetermined pattern formed thereon and a plurality of circuit elements attached onto the conductive layer. The two integrated boards are separated from each other so that the conductive layers of the circuit boards oppose each other. The connector structure is provided with a pair of connecting pin support members which are fixed to the two hybrid integrated circuit boards, and on which a plurality of connecting pins connected to the conductive layers are attached. A connector housing has a fitting hole in which the connecting pin support members are fitted while overlapping each other.
