Elektrisches Verbindungsgehäuse, Verbindungskonstruktion, Fixiervorrichtung für Sammelschienen und Anschlussklemme

To accommodate an electronic circuit board in an electrical connection box without accommodating it in a container. An electronic circuit board 14 is placed above a portion of insulation plates 19 and busbars 13 stacked on a lower casing 11. Circuit portions 14a of the circuit board 14 are electrically connected with the busbars 13 via connection terminals 17. There are provided housings 16 for retaining the connection terminals 17 in terminal chambers arranged side by side therein. The connection terminals 17 are connected with the circuit portions 14a by fitting the housings 16 to the periphery of the circuit board 14 sideways. The circuit board 14 is placed on the upper faces of supports 11c projecting from the lower casing 11 while the connection terminals are fitted to the tabs of the busbars from above. An upper casing 12 is lockingly fixed with the lower casing 11, thereby pressingly fixing the upper surfaces of the housings 16 mounted on the circuit board 14 by shoulder portions 12c provided at the upper casing 12.
