Abstract

A connector includes a housing including a terminal accommodating chamber to accommodate a terminal, and a tubular portion to surround an insertion opening, through which the terminal enters the terminal accommodating chamber, the tubular portion including an opening portion, a water stop member to prevent water from passing through the insertion opening and a holding member to be inserted from the opening portion such that the water stop member is placed between the insertion opening and the holding member, the holding member retaining the water stop member inside the tubular portion. The holding member includes a projection on an outer surface of the holding member toward an inner peripheral surface of the tubular portion at an end portion of the holding member, the end portion is close to the opening portion of the tubular portion when the holding member is fitted in the tubular portion.

First claim

What is claimed is:

1. A connector comprising:
a housing comprising a terminal accommodating chamber configured to accommodate a terminal connected to an end of an electric wire, and a tubular portion provided so as to surround an insertion opening, through which the terminal enters the terminal accommodating chamber, the tubular portion comprising an opening portion;
a water stop member configured to be inserted from the opening portion of the tubular portion, the water stop member configured to prevent water from passing through the insertion opening; and
a holding member configured to be inserted from the opening portion such that the water stop member is placed between the insertion opening and the holding member, the holding member retaining the water stop member in position inside the tubular portion,
wherein the holding member comprises a pair of projections protruding from an outer surface of the holding member toward an inner peripheral surface of the tubular portion at an end portion of the holding member, the end portion being closer to the opening portion of the tubular portion than another end portion of the holding member is to the opening portion of the tubular portion when the holding member is fitted in the tubular portion,
wherein the pair of projections are configured to contact, when the holding member is fitted in the tubular portion, in a pressing manner with the inner peripheral surface of the tubular portion; and
wherein the holding member comprises a locking projection, and the locking projection is located between the pair of projections.

2. The connector according to claim 1 ,
wherein each of the pair of projections comprises an inclined surface extending away from the outer surface of the holding member in a direction opposite to a direction in which the holding member is to be inserted to the tubular portion.

3. A connector comprising:
a housing comprising a terminal accommodating chamber configured to accommodate a terminal connected to an end of an electric wire, and a tubular portion provided so as to surround an insertion opening, through which the terminal enters the terminal accommodating chamber, the tubular portion comprising an opening portion;
a water stop member configured to be inserted from the opening portion of the tubular portion, the water stop member configured to prevent water from passing through the insertion opening; and
a holding member configured to be inserted from the opening portion such that the water stop member is placed between the insertion opening and the holding member, the holding member retaining the water stop member in position inside the tubular portion,
wherein the holding member comprises a projection protruding from an outer surface of the holding member toward an inner peripheral surface of the tubular portion at an end portion of the holding member, the end portion being closer to the opening portion of the tubular portion than another end portion of the holding member is to the opening portion of the tubular portion when the holding member is fitted in the tubular portion,
wherein the projection is configured to contact, when the holding member is fitted in the tubular portion, in a pressing manner with the inner peripheral surface of the tubular portion, and
wherein the holding member has a columnar shape corresponding to a shape of the inner peripheral surface of the tubular portion, and the projection is provided on at least one corner portion of the holding member.

4. The connector according to claim 1 ,
wherein each of the pair of projections has a ridge shape extending about a periphery of the holding member.

5. The connector according to claim 1 ,
wherein each of the pair of projections contacts in a pressing manner with the inner peripheral surface of the tubular portion in an outward direction from the outer surface of the holding member.

6. The connector according to claim 1 ,
wherein each of the pair of projections contacts the inner peripheral surface of the tubular portion in a vertical direction.

7. The connector according to claim 6 ,
wherein the holding member includes a third projection that contacts the inner peripheral surface of the tubular portion in a width direction.

8. A connector comprising:
a housing comprising a terminal accommodating chamber configured to accommodate a terminal connected to an end of an electric wire, and a tubular portion provided so as to surround an insertion opening, through which the terminal enters the terminal accommodating chamber, the tubular portion comprising an opening portion;
a water stop member configured to be inserted from the opening portion of the tubular portion, the water stop member configured to prevent water from passing through the insertion opening; and
a holding member configured to be inserted from the opening portion such that the water stop member is placed between the insertion opening and the holding member, the holding member retaining the water stop member in position inside the tubular portion,
wherein the holding member comprises a projection protruding from an outer surface of the holding member toward an inner peripheral surface of the tubular portion at an end portion of the holding member, the end portion being closer to the opening portion of the tubular portion than another end portion of the holding member is to the opening portion of the tubular portion when the holding member is fitted in the tubular portion,
wherein the projection is configured to contact, when the holding member is fitted in the tubular portion, in a pressing manner with the inner peripheral surface of the tubular portion, and
wherein the projection contacts the inner peripheral surface of the tubular portion on an upper and a lower surface in a vertical direction and on opposing side surfaces in a width direction.
