Patent ID: 7404729

Claim:
An electric connector which includes a plug terminal and a connector housing, the plug terminal having a contact portion in one end and an electric wire connecting portion in the other end, the connector housing accommodating the plug terminal, wherein, in said plug terminal, said contact portion and said electric wire connecting portion are connected to each other through an elastic spring, said connector housing accommodates both the plug terminal and a gate member which holds a contact portion of the plug terminal, the contact portion of said plug terminal is held in said connector housing by said gate member while said spring is compressed and pushed in, and said hold state is released to project the contact portion of said plug terminal from said connector housing in coupling the electric connector to the mating connector, wherein the spring of said plug terminal is formed by connecting a plurality of laterally-facing S-shaped spring units in the same plane, and the laterally-facing S-shaped spring units are elastically expanded and contracted in a longitudinal axis direction of said plug terminal, wherein said contact portion is formed in one end portion of the spring including said coupled laterally-facing S-shaped spring units such that said contact portion is projected toward the longitudinal axis direction of said plug terminal, a fixing portion is formed in the other end portion in order to fix the spring to said connector housing, and said electric wire connecting portion is formed in the fixing portion, and wherein said plug terminal includes two types of first and second plug terminals, electric wire connecting portions of said first and second plug terminals are formed at positions where said fixing portions differ from each other, and the first and second plug terminals are alternately fitted in said connector housing.
