## Abstract

An electrical connector includes an insulating housing; a conductive contact held by the housing, the conductive contact including connection portions exposed on a front side of the housing to be connected to a mating contact of a mating connector and terminal portions protruding from the housing; a cylindrical shell configured to contain the housing, the cylindrical shell including a front shell member and a rear shell member, the front shell member having a fitting portion open forward into which the mating connector is insertable, the rear shell member being provided at the rear of the front shell member so as to protrude the terminal portions therefrom, the rear shell member having a smaller diameter than the front shell member; and an elastically deformable seal member configured to be provided on an outer periphery of the rear shell member.

## Claims

### Claim 1

An electrical connector comprising:
a holding member having an insulation property;
a contact having a conductive property, the contact being held by the holding member, the contact including a connection portion exposed on a front side of the holding member to be connected to a mating contact of a mating connector and a terminal portion protruding from the holding member;
a shell configured to be cylindrical and contain the holding member, the shell including a large diameter portion and a small diameter portion, the large diameter portion having a fitting portion open forward into which the mating connector is insertable, the small diameter portion being provided at the rear of the large diameter portion so as to protrude the terminal portion therefrom, the small diameter portion having a smaller diameter than the large diameter portion; and
a seal member configured to be elastically deformable and be provided on an outer periphery of the small diameter portion, wherein
the shell comprises a front shell member having at least the large diameter portion, and a rear shell member having at least the small diameter portion, the rear shell member being formed as a separate member from the front shell member, and
the front shell member and the rear shell member are electrically connected to each other.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein
the seal member includes a press contact portion configured to protrude laterally relative to the large diameter portion so as to be in press contact with an installation member.

### Claim 3 (depends on 1)

The electrical connector according to claim 1, wherein
the seal member is in contact with a rear end of the large diameter portion.

### Claim 4

(canceled)

### Claim 5

An electrical connector comprising:
a holding member having an insulation property;
a contact having a conductive property, the contact being held by the holding member, the contact including a connection portion exposed on a front side of the holding member to be connected to a mating contact of a mating connector and a terminal portion protruding from the holding member;
a shell configured to be cylindrical and contain the holding member, the shell including a large diameter portion and a small diameter portion, the large diameter portion having a fitting portion open forward into which the mating connector is insertable, the small diameter portion being provided at the rear of the large diameter portion so as to protrude the terminal portion therefrom, the small diameter portion having a smaller diameter than the large diameter portion; and
a seal member configured to be elastically deformable and be provided on an outer periphery of the small diameter portion, wherein
the seal member has a conductive property.

### Claim 6 (depends on 5)

The electrical connector according to claim 5, wherein
the seal member includes a press contact portion configured to protrude laterally relative to the large diameter portion so as to be in press contact with an installation member.

### Claim 7 (depends on 5)

The electrical connector according to claim 5, wherein
the seal member is in contact with a rear end of the large diameter portion.
