## Abstract

A female connector housing is formed by arranging a fixed terminal holder so as to be fixed on an outer housing and arranging a movable terminal holder so as to be movable in a direction of insertion. The movable terminal holder is held with a front end thereof being ahead of the fixed terminal holder in the direction of insertion. Therefore, when the female connector housing is inserted into a male connector housing, a terminal group arranged on the movable terminal holder is first coupled, and a terminal group arranged on the fixed terminal holder is then coupled. In other words, all the terminals are coupled while divided into two groups at a single inserting stroke.

## Claims

### Claim 1

A connector device for connecting first terminal group mounted with second terminal group, said connector device comprising:
a first connector housing for mounting said first terminal group therein;
a second connector housing for mounting said second terminal group therein comprising:
an outer housing:
a fixed terminal holder having a plurality of terminals and being arranged within said outer housing so as to be fixed;
a movable terminal holder having a plurality of terminals and being arranged within said outer housing so as to be movable in a direction in which said second connector housing is inserted into said first connector housing;
wherein said movable terminal holder is temporarily locked with a front end thereof being ahead of said fixed terminal holder in the connector housing insertion direction.

### Claim 2 (depends on 1)

A connector device as claimed in claim 1, wherein said movable holder are temporarily locked with said fixed holder until the terminals in said movable holder are connected to the terminals of the first terminal group corresponding thereto, whereas the temporal locking is released upon connecting the movable holder to said first connecting housing.

### Claim 3 (depends on 1)

A connector device as claimed in claim 1, wherein said movable holder and said fixed holder respectively include a locking means for temporarily locking said movable holder with said fixed holder, and said first connecting housing includes a locking releasing means for releasing an engagement of said locking means when said movable holder is completely coupled with said first connector housing.

### Claim 4 (depends on 3)

A connector device as claimed in claim 3, wherein said locking means is made of a deformable material.
