## Abstract

It is aimed to provide a terminal fitting and a connector capable of ensuring connection reliability. A terminal fitting includes a terminal connecting portion to be connected to a mating terminal fitting and a board connecting portion to be connected to a circuit board. The terminal connecting portion is provided in a first member. The board connecting portion is provided in a second member different from the first member. The first member and the second member are so coupled that relative positions of the terminal connecting portion and the board connecting portion are displaceable. A housing includes a supporting portion for rotatably supporting the first member and the second member.

## Claims

### Claim 1

A connector, comprising:
a terminal fitting; and
a housing for disposing the terminal fitting,
the terminal fitting including:
a first fitting including:
a terminal connecting portion to be connected to a mating terminal fitting; and
a second fitting including:
a base portion extending in a front-rear direction;
a resilient portion provided on a front end portion of the base portion and including a bearing portion;
an extending portion extending downward from a rear end portion of the base portion; and
a board connecting portion provided on an end portion of the extending portion, extending in the front-rear direction, and to be connected to a circuit board,
wherein:
the first fitting is provided with a shaft portion to be fit into the bearing portion of the resilient portion of the second fitting,
the first fitting is rotatably coupled to the second fitting such that relative positions of the terminal connecting portion and the board connecting portion are displaceable with respect to each other, and
the housing includes a supporting portion for rotatably supporting the first and second fittings.

### Claim 2 (depends on 1)

The connector of claim 1, wherein a center of gravity of the terminal fitting is located on the second fitting.

### Claim 3 (depends on 1)

The connector of claim 1, wherein the relative positions of the board connecting portion and the terminal connecting portion are displaceable in a direction orthogonal to a direction in which the resilient portion is deflected and deformed.

### Claim 4 (depends on 1)

The connector of claim 1, wherein the board connecting portion contacts the circuit board, and
the relative positions of the terminal connecting portion and the board connecting portion are displaceable with respect to each other in response to deformation of the circuit board.
