Electric connector for circuit board

摘要

A fitting portion 21 of a terminal 20 is formed in an inverted U character shape along an outer surface and an upper surface of a housing sidewall portion and an interior of a receptacle groove 16; an elastic arm portion 22 bends and extends from the fitting portion to form a U character shape; the bent portion reaches a bottom portion 14B of the receptacle groove in a connector fitting direction; the elastic arm portion extends upward inside the receptacle groove from the bent portion and has elasticity in an area up to a free edge; the elastic arm portion has a contact portion 22A slightly protruding from the inner side surface 14C of the fitting recess portion; the fitting recess portion 14 forms a space between the inner side surface and an opposite inner side surface for receiving a fitting contact portion of the mating connector; the fitting contact portion of the mating connector presses the contact portion 22A of the terminal toward inside the receptacle groove 16; and a distal portion of the fitting contact portion in a connector fitting direction enters toward a bottom portion of the fitting recess portion up to a position substantially the same as that of the bent portion of the terminal.
