Connection terminal chain and method of production thereof

A method of producing a connection terminal chain comprising the steps of:

• punching a development out of an electrically-conductive metal plate, said development including at least two flatly-developed terminal-connecting portions, each of said at least two terminal connecting portions having two major and two minor side walls such that said major side walls are greater in width than said minor side walls, a connecting strip to which said at least two terminal-connecting portions are connected forming a chain through a connecting portion extended from any one of said two minor side walls of each of said at least two terminal-connecting portions;
• folding said development to form said at least two terminal-connecting portions into a box-shape being rectangular in cross section, wherein said folding step includes bending said connecting strip into a V-shaped configuration;
• and
• cutting said connecting strip at predetermined positions.

• folding said development to form said at least two terminal-connecting portions into a box-shape being rectangular in cross section, wherein said folding step includes:
• folding an electric contact piece through an angle of slightly less than 180 degrees so that said electric contact piece will be within said terminal-connecting portion when folding is commenced;
• mating an engaging flap with an engaging slit for a first and second terminal connecting-portion;
• mating a fixing wall with an engaging slit for a third terminal-connecting portion;
• and
• bending said connecting strip into a V-shaped configuration;
• and cutting said connecting strip at predetermined positions.
