## Abstract

A connector includes: a terminal fitting; a housing containing the terminal fitting inside and provided with a fitting portion inserted and fitted into inside of a hole-shaped counterpart fitting portion of a counterpart wall member; a shield shell including a cylindrical portion covering, from outside, a projecting portion of the housing, a flange portion projecting outer than an outer circumferential surface of the cylindrical portion, and a fixed portion bent from an end portion of the flange portion and fixed on an end surface of the counterpart wall member; and an annular water stop member attached to the flange portion and pressed between the flange portion and the wall surface of the counterpart wall member. The shield shell is provided with a through hole provided in a bent portion between the flange portion and the fixed portion and causing inside and outside thereof to communicate with each other.

## Claims

### Claim 1

A connector comprising:
a terminal fitting attached to a terminal of an electrical wire;
a housing containing the terminal fitting inside and provided with a fitting portion inserted and fitted into inside of a hole-shaped counterpart fitting portion of a counterpart wall member;
a shield shell including a cylindrical portion, a flange portion, and a fixed portion, the cylindrical portion covering, from outside, a projecting portion of the housing projecting from the counterpart fitting portion on a side opposite to an insertion direction of the fitting portion into the counterpart fitting portion, the flange portion projecting outer than an outer circumferential surface of the cylindrical portion and disposed opposite to a wall surface of the counterpart wall member with a space therebetween, the fixed portion being bent from an end portion of the flange portion and fixed on an end surface of the counterpart wall member; and
an annular water stop member attached to the flange portion and pressed between the flange portion and the wall surface of the counterpart wall member, wherein
the shield shell is provided with a through hole provided in a bent portion between the flange portion and the fixed portion and causing inside and outside thereof to communicate with each other.

### Claim 2 (depends on 1)

The connector according to claim 1, wherein
the through hole is disposed opposite to the water stop member without any space therebetween in an insertion/extraction direction of the fitting portion with respect to the counterpart fitting portion, and provided with a space from the water stop member except the oppositely disposed portion.

### Claim 3 (depends on 1)

The connector according to claim 1, wherein
the through hole is formed to extend to the flange portion and extend to the fixed portion.

### Claim 4 (depends on 2)

The connector according to claim 2, wherein
the through hole is formed to extend to the flange portion and extend to the fixed portion.

### Claim 5 (depends on 1)

The connector according to claim 1, wherein
the through hole is provided in a place located inside a curve of the bent portion and having a minimum distance from the water stop member before the through hole is provided.

### Claim 6 (depends on 2)

The connector according to claim 2, wherein
the through hole is provided in a place located inside a curve of the bent portion and having a minimum distance from the water stop member before the through hole is provided.

### Claim 7 (depends on 3)

The connector according to claim 3, wherein
the through hole is provided in a place located inside a curve of the bent portion and having a minimum distance from the water stop member before the through hole is provided.

### Claim 8 (depends on 4)

The connector according to claim 4, wherein
the through hole is provided in a place located inside a curve of the bent portion and having a minimum distance from the water stop member before the through hole is provided.
