A bus bar connecting device according to the invention comprises a clamper for clamping first and second bus bars disposed to extend at an angle with each other. The clamper is preferably electrically conductive to permit passage of an electric current therethrough. The second bus bar may have a hole, and a bolt extends through the clamper and the hole of the second bus bar, and screwed into a nut provided on the opposite side of the second bus bar. As the bolt is screwed into the nut, the clamper is pressed against the bus bars, and also presses the first and second bus bars against each other. Preferably, the clamper has linear protrusions at which it is in contact with the bus bars. Because of the pressure contact along the entire linear protrusions, the area of contact is larger than if the contact is made only at a point. The device is provided with a mechanism to prevent shift of the second bus bar in the lateral direction of the first bus bar. Such a mechanism may consist of a step of the clamper. Such a mechanism may additionally consist of a bent end of the second bus bar or a protrusion provided on the second bus bar. Such a mechanism may alternatively be in the form of an elongated dent or groove provided on the first bus bar with which one of the linear protrusions of the clamper is engaged. |
