Abstract: A coaxial connector and a method for providing a normal force in an electrical connector. The coaxial connector includes a first terminal having a first contact portion and a second terminal having a second contact portion. Before an external device is inserted into the coaxial connector for the first time, the first contact portion and the second contact portion form a first relative positional relationship.
