Abstract

A female terminal includes a male terminal inserting tube portion constituting a connecting portion by an inner surface to be press-fit by a male terminal, a pair of overlapping plate portions connected to a pair of first divided portions of the male terminal inserting tube portion, separated from each other and projecting outward, and a clip having a coupling plate portion, a pair of sandwiching plate portions and an insertion opening between projecting end parts of the pair of sandwiching plate portions. The pair of overlapping plate portions press-fit between the pair of sandwiching plate portions through the insertion opening of the clip are biased to be overlapped each other between the pair of sandwiching plate portions by resilient restoring forces of the pair of sandwiching plate portions.

First claim

What is claimed is:

1. A female terminal, comprising:
a female terminal fitting including a connecting portion to be conductively connected to a male terminal;
a male terminal inserting tube portion provided in the female terminal fitting, the male terminal inserting tube portion constituting the connecting portion by an inner surface to be press-fit by the male terminal;
a pair of first divided portions provided by dividing the male terminal inserting tube portion over an entire length in an axial direction at one circumferential position,
a pair of overlapping plate portions connected to the pair of first divided portions, the pair of overlapping plate portions being and separated from each other and projecting outward;
a pair of second divided portions provided by dividing the male terminal inserting tube portion over the entire length in the axial direction at another circumferential position;
a pair of extending plate portions connected to the pair of second divided portions and projecting outward; and
a clip held on the female terminal fitting, the clip including a coupling plate portion and a pair of sandwiching plate portions projecting in directions approaching each other from both side edge parts of the coupling plate portion such that a clearance serving as an insertion opening is provided between projecting end parts of the pair of sandwiching plate portions,
wherein:
the pair of overlapping plate portions press-fit between the pair of sandwiching plate portions through the insertion opening of the clip are pressed by resilient restoring forces of the pair of sandwiching plate portions such that the pair of overlapping plate portions come into contact with each other between the pair of sandwiching plate portions,
the male terminal inserting tube portion is resiliently deformed in a diameter expanding direction due to the resilient restoring forces of the pair of sandwiching plate portions to cause the male terminal to be press-fit into the male terminal inserting tube portion when the male terminal is press-fit into the male terminal inserting tube portion,
the first divided portions and the second divided portions are provided at positions separated by 90° in the circumferential direction of the male terminal inserting tube portion, and
the overlapping plate portion and the extending plate portions are configured to project in directions orthogonal to each other.

2. The female terminal according to claim 1 , wherein the clip is held on the female terminal fitting by engagement of lock holes provided in either the pair of sandwiching plate portions or the pair of overlapping plate portions, the pair of sandwiching plate portions being respectively overlapped on the pair of overlapping plate portions, and lock claws provided on the others.

3. The female terminal according to claim 1 , wherein:
extending end parts of the pair of extending plate portions are connected to a wire crimping portion provided in a base end part of the female terminal fitting and the pair of extending plate portions are arranged to face each other across a clearance over an entire length.

4. The female terminal according to claim 1 , wherein tip parts in a projecting direction of the pair of overlapping plate portions are sandwiched between the pair of sandwiching plate portions of the clip, and both side end parts in a width direction of the tip parts of the pair of overlapping plate portions are bent toward sides opposite to overlapping directions, thereby providing pairs of protection wall portions arranged outwardly of the pair of sandwiching plate portions of the clip in the width direction.

5. The female terminal according to claim 4 , wherein outer surfaces of the pairs of protection wall portions constitute contact supporting surfaces to be brought into contact with and supported by an inner surface of a housing into which the female terminal fitting is accommodated.
