    摘要: An overhead installed communication system includes a cabinet body which includes an electronic circuit device and a door which is supported by the cabinet body through a hinge so that the door can be opened and closed. The system is installed overhead and external cables are introduced into the system. A box is provided inside the door, and the box is sealed in a condition where a lid is closed. A connector is provided in the box, electric wires extending from the electronic circuit device are connected to the connector and the external cables are connected to the connector after being introduced into the system.

    摘要: A cooling structure for LSI or the like devices to be mounted in a small size electronic apparatus housing. A main printed circuit board has mounted thereon first electronic devices with low heat generation; at least one auxiliary printed circuit board has mounted thereon a second electronic device with high heat generation, which is connected with one edge of the main printed circuit board (1) through a flexible printed circuit tape (5); a holder (6) fixed on the main printed circuit board (1) for resiliently supporting the auxiliary printed circuit board (2) at a distance above the former when the latter is turned over and is above the main printed circuit board (1) by bending the flexible printed circuit tape (5) so that a heat conductive surface of the second electronic device (4) is exposed outside. This printed circuit board assembly (A) is accommodated in a housing (B) made of a heat conductive material so that the heat conductive surface of the second electronic device (4) is brought into close and resilient contact with the inner wall (14) of the hosing (B).

    摘要: In a connector mounting structure, a printed-wiring board has a cut portion, a modular connector connecting pattern provided adjacent to the cut portion, and a connecting pattern provided isolated from the modular connector connecting pattern and connecting an SFP connector. Also, the printed-wiring board and a front board are combined in order that the cut portion faces a plane of an opening which the front board has. When a modular connector is inserted into the opening, the modular connector is supported by the opening and the cut portion and concurrently the modular connector is electrically contacted with the modular connector connecting pattern. When an SFP front cage is inserted into the opening, the SFP front cage is supported by the opening and the cut portion and concurrently an SFP module becomes connectable to the SFP connector through the SFP front cage.
