Abstract: A connector housing apparatus includes a main body section that has a plurality of connectors confronting a plurality of external connectors of an external housing and a moving guide section that guides movement of the main body section toward the external housing. The moving guide section has a latching section that latches the moving guide section on the external housing. The main body section is connected to the moving guide section so as to be movable in a fitting direction of the plurality of connectors. The latching section latches the moving guide section on a position at which the plurality of connectors are fitted to the plurality of external connectors. The main body section moves along the moving guide section in the fitting direction of the plurality of connectors, and thereby the plurality of connectors are fitted to the plurality of external connectors.

Abstract: In an electronic device, when a 48 V feed system is shifted to a 12 V feed system, in order to supply the same electric power, a current of fourth times needs to flow into a backplane. Also, in an anteroposterior intake and exhaust system, there is a need to form a ventilator through which a cooling air passes in the backplane. Further, there arises a problem that a mechanical strength is deteriorated by provision of the ventilator in the backplane. There is provided a structure in which a pinnate projection is provided on a feed bus bar, and a cooling air is applied to the feed bus bar. Also, the feed bus bar is brought into close contact with an overall surface of the backplane, and electrically and mechanically connected thereto at multiple points, to thereby perform both of cooling and the suppression of stiffness deterioration.

Abstract: A simple configuration for cooling comprises a front-back air supply and exhaust system. A first circuit board is located in front of a relay circuit board. A cooling unit and a second circuit board are placed behind the relay circuit board in a chassis. A first air passage allows intake air through an intake hole in a front side of the first circuit board unit to pass through the first circuit board and then through an opening in the relay circuit board to the cooling unit. A second air passage allows intake air through an intake hole in a front face of the chassis to pass through a lateral side of the first circuit board and then through a vent hole in a partition provided at the lateral side of the first circuit board. The second circuit board is placed in the second air passage.
