  • Patent number: 11615935
    Abstract: Flat surfaces out of two flat surfaces of each of flat electrical connection bodies of a relay bus bar and a bus bar of an electronic component are mating surfaces brought into contact with each other by a fixing structure. At least one of the flat electrical connection bodies of the relay bus bar and the bus bar applies a reaction force accompanying the elastic deformation to the other flat electrical connection body, to which the one flat electrical connection body is to be connected, in a state in which the flat electrical connection body of the bus bar at an accommodation completion position in a housing has not been connected to the relay bus bar. The housing includes a receiving portion receiving a force applied to the flat electrical connection body of the bus bar from the flat electrical connection body of the relay bus bar.
