Abstract

A connector includes a first housing including a first lock part, a second housing including a second lock part that can be locked to the first lock part, and a fitting detection member that can move from an initial position to a fitting assured position with the second lock part locked to the first lock part and includes a third lock part that can ride over the first lock part and the second lock part in succession along with the movement from the initial position to the fitting assured position to be locked to the second lock part at the fitting assured position. The first lock part includes a drawing slope surface inclining from a protruding tip toward a first lock face and a protrusion protruding from the drawing slope surface. The second lock part includes a notch that can house the protrusion.

First claim

What is claimed is:

1. A connector comprising:
a first housing provided with a first terminal and including a first lock part formed to protrude from an outer face;
a second housing provided with a second terminal to be connected to the first terminal, configured to be capable of being fit into the first housing, and including a second lock part capable of riding over the first lock part to be locked to the first lock part while being fit into the first housing; and
a fitting detection member assembled to the second housing, being capable of moving from an initial position to a fitting assured position with the second lock part locked to the first lock part, and including a third lock part capable of riding over the first lock part and the second lock part locked to the first lock part in succession along with the movement from the initial position to the fitting assured position to be locked to the second lock part at the fitting assured position, wherein
the first lock part includes a first lock face locking the second lock part, a drawing slope surface inclining from a side of a protruding tip toward a side of the first lock face, and a protrusion protruding from the drawing slope surface, and
the second lock part includes a guide part facing the first lock part when the second lock part rides on the first lock part, and a notch that is formed in a recessed shape in the guide part and is capable of housing the protrusion.

2. The connector according to claim 1 , wherein
the protrusion protrudes within a space formed between the protruding tip of the first lock part, the drawing slope surface, and the second lock part with the second lock part locked to the first lock part.

3. The connector according to claim 2 , wherein
the second lock part includes a second lock face to be locked to the first lock face of the first lock part, and
the notch is formed along a direction of relative movement of the first lock part and the second lock part when the second lock part rides over the first lock part, extends up to the second lock face, and avoids contact between the second lock part and the protrusion along with the relative movement of the first lock part and the second lock part.

4. The connector according to claim 2 , wherein
the third lock part comes into contact with the second lock part and is regulated movement thereof from the initial position to the fitting assured position with the second lock part not being locked to the first lock part, and rides on the first lock part to be able to move from the initial position to the fitting assured position with the second lock part being locked to the first lock part.

5. The connector according to claim 1 , wherein
the third lock part comes into contact with the second lock part and is regulated movement thereof from the initial position to the fitting assured position with the second lock part not being locked to the first lock part, and rides on the first lock part to be able to move from the initial position to the fitting assured position with the second lock part being locked to the first lock part.

6. The connector according to claim 1 , wherein
the second lock part includes a second lock face to be locked to the first lock face of the first lock part, and
the notch is formed along a direction of relative movement of the first lock part and the second lock part when the second lock part rides over the first lock part, extends up to the second lock face, and avoids contact between the second lock part and the protrusion along with the relative movement of the first lock part and the second lock part.

7. The connector according to claim 6 , wherein
the third lock part comes into contact with the second lock part and is regulated movement thereof from the initial position to the fitting assured position with the second lock part not being locked to the first lock part, and rides on the first lock part to be able to move from the initial position to the fitting assured position with the second lock part being locked to the first lock part.
