ABSTRACT:
The present invention is to provide a terminal having a stable electric contact without reducing supporting force of the terminal. The terminal is force fitted into a through-hole of a circuit board and connected to conductive portions inside the through-hole electrically. The terminal includes resilient contact portions at both sides of escape spaces formed through in the thickness direction of the insertion portion and the resilient contact portions are elastic along the long axis of the through-hole and are connected with the conductive portions inside the through-hole. The terminal also includes a plurality of leaf spring contact pieces in the escape spaces which are resilient in the short axis of the through-hole and connected electrically to the walls of the through-hole. Locking protrusions are formed at tip end of the insertion portion to engage with an edge of the through-hole. The leaf spring contact pieces have the curved faces which are oriented in opposite directions to each other, and contact to the opposing walls of the through-hole.
