Terminal structure of electrical equipment

Abstract

To provide a terminal structure of an electrical device that has a plurality of terminals for electrical connection with an external device inside a housing, while enabling the size of the housing to be reduced.SOLUTION: A power conversion device 100 includes bus bars 152 to 154 and a case 101. The case 101 has a tool insertion opening 101c. The connection portions 152a, 153a, 154a of the bus bars 152 to 154 have through holes 152b, 153b, 154b through which bolts for connection are passed. When viewed from one side in the right-left direction, the normal lines Ax152, Ax153, Ax154 of the connection portions 152a, 153a, 154a pass through the tool insertion opening 101c through the points P12 to P14. When the distance between the intersection of the normal line Ax152 and the joint surface of a joint 152a and the intersection of the normal line Ax153 and the joint surface of a joint 153a in the up-down direction is determined as L7, the distance L11 between the point P12 and the point P13 is shorter than the distance L7.SELECTED DRAWING: Figure 7
