Terminal for charging with large current
First Claim
1. A terminal for charging with large current, comprising:
- a female terminal having a terminal accommodating chamber to accommodate a rod-like male terminal, the terminal accommodating chamber having an inlet portion with a larger diameter formed at an inlet thereof;
a contact spring member consisting of a plurality of arced leaf spring pieces integrally linked at one side thereby to form a shape corresponding to an outer diameter of the male terminal and to an inner diameter of the terminal accommodating chamber of the female terminal, and having a fixing rib projecting in a radial direction from the one side integrally linked so as to abut the fixing rib on an inlet wall portion provided on an inner end of the inlet portion of the female terminal; and
a cap having a terminal insertion hole to put the male terminal therethrough and attached to the inlet portion of the female terminal to hold the fixing rib of the contact spring member so as to fix the contact spring member in the terminal accommodating chamber of the female terminal;
wherein each of ends on the other side, being not integrally linked, of the leaf spring pieces of the contact spring member is capable of freely sliding on a surface of the terminal accommodating chamber in an axial direction thereof upon insertion or pulling-out of the male terminal so that each of the leaf spring pieces is in contact with an outer surface of the male terminal, thereby attaining secure electrical contact between the male terminal and the female terminal.

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.

4. A terminal for changing with large current, comprising:
-
a female terminal having a terminal accommodating chamber to accommodate a rod-like male terminal, the terminal accommodating chamber having an engaging recess formed near an inlet thereof; and a contact spring member consisting of a plurality of arced leaf spring pieces integrally linked at one side thereby to form a shape corresponding to an outer diameter of the male terminal and to an inner diameter of the terminal accommodating chamber of the female terminal, and having a plurality of engaging pieces on the one side integrally linked so as to engage the engaging recess on the female terminal; wherein each of ends on the other side, being not integrally linked, of the leaf spring pieces of the contact spring member is capable of freely sliding on a surface of the terminal accommodating chamber in an axial direction thereof upon insertion or pulling-out of the male terminal so that each of the leaf spring pieces is in contact with an outer surface of the male terminal, thereby attaining secure electrical contact between the male terminal and the female terminal. - View Dependent Claims (5, 9, 10)
