Les parties d'extension supérieure et inférieure (132a-132d et 142a-142d) de chaque borne supérieure/inférieure ne sont pas partagées avec d'autres bornes supérieures/inférieures. Des parties d'extension tournantes (143a-143d) sont disposées au niveau de l'extrémité avant ou d'un côté de parties de contact supérieures et inférieures (131a-131d et 141a-141d) des bornes supérieures/inférieures. Les deux rangées de bornes supérieures et inférieures peuvent être distendues de manière arbitraire entre différents circuits ou dans la mesure où les circuits ni ne se croisent ni ne se chevauchent, ce qui permet de réduire la difficulté d'un procédé de fabrication et celle d'un procédé d'assemblage, et en même temps de réduire les coûts de fabrication et les coûts d'assemblage du connecteur électrique.
