1-pole male connector (housing) with book tabs 22
23 is provided upright and connected to a female connector (not shown) to supply power. However, since the female connector of the other party becomes relatively large in relation to the current capacity, the corresponding male connector 23 also inevitably becomes large, and the overall thickness of the electrical junction box B increases, which makes installation of the electrical junction box possible. It will require a large space. Moreover, the tab 22 for connecting the power source
Since it is larger than the tabs 22 'of other ordinary connectors 23', the length at the time of punching and expanding from a conductive metal plate is also long, which makes it difficult to design. In addition, if a connector is used for power supply connection, the allowable current value that can be passed through one tab 22 is regulated, so it is necessary to add another connector. With the increase in this connector, the number of joints (branch connection) in the wire harness is increased. And the number of wiring patterns becomes plural.

あるから、共回り防止手段を設ける必要がある。Therefore, there is a method of directly connecting the bus bar in the electric junction box and the external terminal (or bus bar) by bolting instead of connecting the power supply circuit to the connector. In this case, if the inner bus bar co-rotates due to the bolt tightening, there is a risk that it may come into contact with other bus bars or be damaged, so it is necessary to provide co-rotation preventing means.
