## Abstract

A connector includes a connector housing and a cap. The connector housing has a terminal accommodating portion formed with a bottomed tubular cavity. The cap has a cap body configured to cover an opening portion of the cavity, a tubular portion vertically provided on a rear surface of the cap body and configured to be fitted into a tubular inner surface of the cavity in a fitting direction, a contact portion facing an opening edge portion of the cavity, provided on the cap body, and located outward than a root of the tubular portion in a radial direction of the cap body, and a recessed portion provided on the rear surface of the cap body between the root of the tubular portion and the contact portion.

## Claims

### Claim 1

A connector comprising:
a connector housing comprising a terminal accommodating portion formed with a bottomed tubular cavity, wherein a terminal fitting is provided in the tubular cavity and is configured to be connected to a counterpart terminal fitting of a counterpart connector; and
a cap comprising:
a cap body configured to cover an opening portion of the cavity;
a tubular portion vertically provided on a rear surface of the cap body and configured to be fitted into a tubular inner surface of the cavity in a fitting direction;
a contact portion facing an opening edge portion of the cavity, provided on the cap body, and located outward than a root of the tubular portion in a radial direction of the cap body; and
a recessed portion provided on the rear surface of the cap body between the root of the tubular portion and the contact portion.

### Claim 2 (depends on 1)

The connector according to claim 1, wherein an outer peripheral surface of the tubular portion is provided with a plurality of positioning ribs that extend from the recessed portion in the fitting direction and are arranged at equal intervals in a circumferential direction of the outer peripheral surface of the tubular portion.

### Claim 3 (depends on 1)

The connector according to claim 1, wherein the connector housing has a hood portion that surrounds the terminal accommodating portion;
wherein a space that opens forward is provided all over the entire circumference of the connector housing between the hood portion and the terminal accommodating portion so as to allow a counterpart hood portion of the counterpart connector to enter the space; and
wherein the cap body has a flange portion that covers an opening of the space.

### Claim 4 (depends on 1)

The connector according to claim 1, wherein the cap has a fall prevention strap.
