Female connector terminal with internal plate spring

1. A female connector terminal into which a rectangular male connector terminal can be inserted, comprising:

a hollow conductor having a rectangular engagement portion capable of receiving the inserted male connector terminal, the inserted male connector terminal comprising two sides of a contact surface facing in a direction parallel to an insertion direction of the inserted male connector terminal;

a protrusion disposed at the engagement portion of the conductor and brought into contact with the inserted male connector terminal; and

a plate spring disposed at the conductor engagement portion to face the protrusion so that the inserted male connector terminal can be sandwiched between the plate spring and the protrusion,

wherein the plate spring comprises at least two plate members which form abutment portions configured into a predetermined shape by bending plate members and brought into abutment with the two sides of the contact surface of the male connector terminal,

and a plurality of fins aligned in a direction normal to an insertion direction of the male connector terminal bent in a direction similar to the bending of the plate members and support the contact surface of the male connector terminal, thereby suppressing a slide movement of the male connector terminal relative to the female connector terminal in the direction normal to the insertion direction of the inserted male connector terminal.

2. The female connector terminal according to claim 1 , wherein each abutment portion is formed by bending one plate member in a direction opposed

to a bending direction of a second plate member.

3. The female connector terminal according to claim 1 , wherein each abutment portion has a peripheral edge brought into contact with one of two side surfaces of the engagement portion.

4. A female connector comprising the female connector terminal according to claim 1 .
