## Abstract

A female terminal includes a hollow contact portion of a substantially quadrangular cross-section for receiving a male terminal through an opening formed in a front end thereof, so as to establish an electrical connection between the male terminal and the female terminal, and a resilient contact piece, formed in the hollow contact portion by folding a tip portion of the bottom plate portion of the hollow contact portion, for biasing the male terminal toward the roof plate portion of the hollow. The resilient contact piece has a first piece portion which extends from the front end of the hollow contact portion so as to be inclined upwards toward the roof plate portion. The female terminal also includes a plurality of protruding portions extending from the bottom plate portion toward the roof plate portion, for supporting thereon the first piece portion while maintaining the elastic deformation of the first piece portion when an excessive force is applied to the first piece portion.

## Claims

### Claim 1

A female terminal comprising:
a hollow contact portion of a substantially quadrangular cross-section for receiving a male terminal through an opening formed in a front end thereof, so as to establish an electrical connection between the male terminal and the female terminal, said hollow contact portion having a roof plate portion and a bottom plate portion;
a resilient contact piece, formed in said hollow contact portion by folding a tip portion of said bottom plate portion, for biasing said male terminal toward said roof plate portion, said resilient contact piece having a first piece portion which extends from said front end so as to be inclined upwards toward said roof plate portion; and
a plurality of protruding portions extending from said bottom plate portion toward said roof plate portion, for supporting thereon said first piece portion while maintaining the elastic deformation of the first piece portion when an excessive force is applied to said first piece portion.

### Claim 2 (depends on 1)

A female terminal as set forth in claim 1, wherein said plurality of protruding portions are so arranged as to be apart from each other at regular intervals in a longitudinal direction of said female terminal, each of said plurality of protruding portions having a height set in accordance with the inclination of said first piece portion.

### Claim 3 (depends on 2)

A female terminal as set forth in claim 2, wherein each of said plurality of protruding portions is formed by bending a portion cut out of said bottom plate portion in a direction substantially perpendicular to said bottom plate portion.

### Claim 4 (depends on 1)

A female terminal as set forth in claim 1, wherein said resilient contact piece has a second piece portion which extends from the tip of said first piece portion so as to be inclined downwards toward said bottom plate portion.
