## Abstract

A connector C is provided with a housing 30 formed with a through hole 39, a rubber plug 60 to be arranged inside the housing 30 and formed with a sealing hole 61, and a dummy plug 10 to be arranged from the through hole 39 to the sealing hole 61. The housing 30 includes recesses 43 open in an inner surface of the through hole 39. The dummy plug 10 includes a plug body 11 to be arranged in the sealing hole 61, an extending portion 12 continuously extending from the plug body 11 and to be arranged in the through hole 39, and protrusions 16 projecting from an outer peripheral surface of the extending portion 12 and arranged to be press-fit into the recesses 43.

## Claims

### Claim 1

A connector, comprising:
a housing formed with a through hole;
a rubber plug to be arranged inside the housing, the rubber plug being formed with a sealing hole communicating with the through hole; and
a dummy plug to be arranged from the through hole to the sealing hole, wherein:
the housing includes a recess open in an inner surface of the through hole, and the dummy plug includes:
a plug body to be held in close contact with an inner surface of the sealing hole by being arranged in the sealing hole;
an extending portion continuously extending from the plug body, the extending portion being arranged in the through hole; and
a protrusion projecting from an outer peripheral surface of the extending portion, the protrusion being arranged to be press-fit into the recess.

### Claim 2 (depends on 1)

The connector of claim 1, wherein a plurality of the protrusions are arranged at intervals in a circumferential direction on the outer peripheral surface of the extending portion.

### Claim 3 (depends on 2)

The connector of claim 2, wherein a pair of the recesses are arranged in the inner surface of the through hole, and the protrusion is arranged to be press-fit into each of the pair of recesses.

### Claim 4 (depends on 1)

The connector of claim 1, wherein the recess is in the form of a groove extending from an inlet for introducing the protrusion toward a side communicating with the sealing hole in the inner surface of the through hole and has a pair of inclined surfaces expanded toward the inlet on a pair of facing side surfaces.

### Claim 5 (depends on 4)

The connector of claim 4, wherein:
the inner surface of the through hole includes a pair of short side portions facing each other and a pair of long side portions facing each other while intersecting the pair of short side portions and longer than the short side portions in the housing,
the recess is open in the long side portion, and
the pair of inclined surfaces are inclined to approach the short side portions toward the inlet on the long side portion.
