Abstract

There is provided a connector including: a terminal fitting including a terminal portion, a conductor connection portion, and a connecting portion that connects the terminal portion and the conductor connection portion; a housing including an accommodating chamber that accommodates the terminal fitting from the terminal portion to the connecting portion, and a terminal drawing port that allows the conductor connection portion to be drawn out of the accommodating chamber toward a removal direction of the terminal portion; and a conductive component soldering a conductor to the conductor connection portion inserted into a through-hole, in which the connecting portion includes a first coupling portion that is coupled to the terminal portion, a second coupling portion that is coupled to the conductor connection portion, and a third coupling portion.

First claim

What is claimed is:

1 . A connector comprising:
a terminal fitting including a terminal portion that is fitted into and connected to a counterpart terminal portion, a conductor connection portion, and a connecting portion that connects the terminal portion and the conductor connection portion; a housing including an accommodating chamber that accommodates the terminal fitting from the terminal portion to the connecting portion, and a terminal drawing port that allows the conductor connection portion to be drawn out of the accommodating chamber toward a removal direction of the terminal portion with respect to the counterpart terminal portion; and a conductive component formed as a laminate of a conductor and an insulator with a through-hole, and soldering the conductor to the conductor connection portion inserted into the through-hole and physically and electrically connecting the conductor connection portion and the conductor, wherein the connecting portion includes a first coupling portion that is coupled to the terminal portion, a second coupling portion that is coupled to the conductor connection portion, and a third coupling portion that is elastically deformable and connecting the first coupling portion and the second coupling portion, and the connecting portion in the accommodating chamber allows the conductor connection portion to extend in the removal direction in a state in which a first resilient force due to elastic deformation of the third coupling portion is applied from the terminal portion to a first inner wall portion of the accommodating chamber and in a state in which a second resilient force opposite to the first resilient force due to the elastic deformation of the third coupling portion is applied from the second coupling portion to a second inner wall portion of the accommodating chamber.

2 . The connector according to claim 1 , wherein
the elastic deformation of the third coupling portion in the accommodating chamber allows the second coupling portion to be displaced from an extending direction in a direction intersecting with the removal direction to an extending direction in the removal direction.

3 . The connector according to claim 1 , wherein
the third coupling portion is formed in a crank shape in which the first coupling portion and the second coupling portion are offset in a direction orthogonal to the removal direction.

4 . The connector according to claim 2 , wherein
the third coupling portion is formed in a crank shape in which the first coupling portion and the second coupling portion are offset in a direction orthogonal to the removal direction.

5 . The connector according to claim 3 , wherein
the accommodating chamber includes a first accommodating portion that accommodates the terminal portion and the first coupling portion, and a second accommodating portion that accommodates the second coupling portion, the first accommodating portion includes a third inner wall portion arranged to face the first inner wall portion opposite to an applying direction of the first resilient force, and the second accommodating portion includes a second inner wall portion offset in an applying direction of the second resilient force from the third inner wall portion.

6 . The connector according to claim 1 , wherein
the connecting portion includes a projection portion that protrudes from the second coupling portion, and the accommodating chamber includes a projection locking portion that locks the projection portion opposite to the applying direction of the second resilient force while allowing the conductor connection portion to extend in the removal direction.

7 . The connector according to claim 2 , wherein
the connecting portion includes a projection portion that protrudes from the second coupling portion, and the accommodating chamber includes a projection locking portion that locks the projection portion opposite to the applying direction of the second resilient force while allowing the conductor connection portion to extend in the removal direction.

8 . The connector according to claim 3 , wherein
the connecting portion includes a projection portion that protrudes from the second coupling portion, and the accommodating chamber includes a projection locking portion that locks the projection portion opposite to the applying direction of the second resilient force while allowing the conductor connection portion to extend in the removal direction.

9 . The connector according to claim 5 , wherein
the connecting portion includes a projection portion that protrudes from the second coupling portion, and the accommodating chamber includes a projection locking portion that locks the projection portion opposite to the applying direction of the second resilient force while allowing the conductor connection portion to extend in the removal direction.
