Abstract

A female terminal for being connected to a male terminal comprises a terminal body having an opening through which the male terminal is inserted, and a wire connecting part for being connected to a wire. A flexible element is mounted on the terminal body, for pressing the male terminal inserted into the terminal body, against the terminal body. In order that the flexible element is flexed beforehand to facilitate insertion of the male terminal, a pair of engaging projections are integrally formed on the flexible element, while a pair of engaging sections are formed on the terminal body in order that the pair of engaging projections are engaged respectively with the pair of engaging sections.

Claims

1. A female terminal for being connected to a male terminal, comprising:

a terminal body having an opening through which said male terminal is inserted in an inserting direction, and a wiring connecting part for being connected to a wire;

a flexible element disposed in said terminal body, for pressing against said male terminal inserted into said terminal body; and

stop means provided in said terminal body for restraining a center portion of said flexible element in a preloaded condition prior to the insertion of said male terminal into said terminal body so as to reduce the initial insertion force of said male terminal therein, and wherein said center portion is restrained against substantial deflection in a flexing direction away from said male terminal.

2. A female terminal for being connected to a male terminal, according to claim 1, wherein

said flexible element is comprised of a leaf spring having a curved section at both ends,

wherein said restraining means comprises a pair of fixing projections formed integrally with one of the ends of said leaf spring, a pair of preliminary-displacement projections formed on the curved section of said leaf spring at said center portion thereof, a pair of fixing engaging sections formed in said terminal body for being engaged respectively with said pair of fixing projections, and a pair of preliminary-displacement engaging sections formed in said terminal body for being engaged respectively with said pair of preliminary-displacement projections, each of said projections and each of said engaging sections being so arranged as to preload said flexible element so as to reduce the initial insertion force of said male terminal into said terminal body after said flexible element is mounted on said terminal body.

3. A female terminal for being connected to a male terminal, according to claim 1, wherein

said flexible element is comprised of a leaf spring having a curved section at both ends, and

said means for flexing said flexible element prior to the insertion of said male terminal into said terminal body comprises an abutting portion formed on the both ends of said flexible element to abut against said terminal body, a pair of engaging projections formed on the curved section of said flexible element, and a pair of engaging sections formed on said terminal body for being engaged respectively with said pair of engaging projections, said engaging projections and said engaging sections being so arranged as to urge said abutting portion against said terminal body and to flex said flexible element so as to reduce the initial insertion force of said male terminal into said terminal body after said flexible element is mounted on said terminal body.

4. A female terminal for being connected to a male terminal according to claim 1, wherein said restraining means comprises a pair of laterally-extending projections provided at said center portion of said flexible element, and a pair of recesses formed in said terminal body for receiving said projections.
