CONNECTION STRUCTURE BETWEEN METAL PLATES

摘要

A connection structure between two metal plates for mutually positioning and electrically connecting the metal plates is provided by a simple press-in process without using an additional connection part. A curved blade plate curving with a curvature smaller than that of a cylindrical inner wall surface of an insertion hole in one of the metal plates in the same direction as that of the cylindrical inner wall is formed on the other metal plate. The curved blade plate is pressed into the insertion hole while being elastically deformed in the curving direction, so that edges along both side edges of a curved outer peripheral surface each make press contact with the cylindrical inner wall surface. The metal plates are thereby fixed and electrically connected to each other.

1. A connection structure between metal plates, comprising:
a first metal plate having an insertion hole formed therein, the insertion hole having an inner surface at least part of which being formed as a cylindrical inner wall surface curving along an arc; and a second metal plate having a contact portion which is inserted into the insertion hole, so as to relatively position the first metal plate and the second metal plate and put the contact portion into contact with the cylindrical inner wall surface to electrically connect the first metal plate and the second metal plate, wherein: the connection portion is made of a curved blade plate curving with a curvature smaller than that of the cylindrical inner wall surface in the same direction as that of the cylindrical inner wall surface; and the curved blade plate is pressed into the insertion hole while being elastically deformed in the curving direction so that edges along both side edges of a curving outer peripheral surface thereof each make press contact with the cylindrical inner wall surface.
