ABSTRACT:
A terminal for charging with large current, used for charge of an electric vehicle for example, is provided, wherein unequal deformation of leaf spring pieces acting as contacts on a female terminal side is prevented for attaining sure electrical contact between a male terminal and a female terminal. The terminal includes: a female terminal having a terminal accommodating chamber with an inlet portion having a larger diameter formed at an inlet thereof for accommodating a rod-like male terminal; a contact spring member with a lot of arced leaf spring pieces integrally linked at one side to form a substantially cylindrical shape and a fixing rib projecting in a radial direction to abut on an inlet wall portion of the inlet portion; and a cap having a terminal insertion hole to put the male terminal therethrough and attached to the inlet portion to hold the fixing rib for fixing the contact spring member in the terminal accommodating chamber. Thus, each of free ends of the leaf spring pieces is capable of freely sliding on a surface of the terminal accommodating chamber in the axial direction upon insertion or pulling-out of the male terminal so that each of the leaf spring pieces surely gets in contact with an outer surface of the male terminal for attaining sure electrical contact between the male and female terminals.
