Par conséquent, il n'est pas nécessaire pour l'élément électriquement conducteur (3) d'avoir une force élastique ; l'élément électriquement conducteur (3) peut ainsi être conçu à partir d'un matériau ayant une conductivité électrique élevée, ce qui permet d'accroître la conductivité électrique d'un connecteur électrique (1). En outre, il n'est pas nécessaire pour le manchon (2) d'être électriquement conducteur ; le manchon (2) peut ainsi être conçu à partir d'un matériau ayant une force élastique suffisante.
