Abstract: A riveting structure comprises a connector and a metal plate. The proposed riveting structure differs from the prior art in that the connector has an even number of parallel positioning sides and the shape of an opening on the metal plate corresponds to that of a connection member on the connector so that the connector can be positioned in the opening. Moreover, the width of parallel sides of the opening can be properly adjusted to meet the requirement of various different torques.

Abstract: An electric facility includes a board having a number of openings formed in the peripheral portion and a number of conductors applied around the openings. A number of casings are engaged in the openings of the board and electrically coupled to the conductors of the board. A number of terminals each has one end engaged into the casing for being grounded to the board by the casing and the conductors. The casing includes two side panels and one or more end panels for engaging with the terminal. The side panels each has a flap for engaging with and for retaining the terminal in the casing.
