Abstract

The outer peripheral surface of a connector, to which a connector seal structure is applied, is provided with an engaging section that engages with a seal member. A rib of the engaging section locks the seal member in the inserting direction of the connector. The seal member is provided with a cutout section formed by cutting out a part of the rib, or a protruding section that engages with the rib.

First claim

The invention claimed is:

1. A connector sealing structure of a connector provided with a terminal portion that is connected to a connecting object, the connector sealing structure comprising:
the connector includes
a housing main body,
a protruding portion that protrudes from the housing main body toward the connecting object, and
the terminal portion that extends from the protruding portion toward the connecting object,

the connector sealing structure includes
a sealing member that is placed on an outer circumferential surface of the protruding portion; and
an engaging portion that is provided on the outer circumferential surface of the protruding portion and engages the sealing member, wherein
the engaging portion includes
a rib that is formed on the outer circumferential surface of the protruding portion and locks the sealing member in a direction in which the connector is inserted into the connecting object, and
a notch portion that is formed by cutting part of the rib out of at least a site that belongs to a side surface of the protruding portion along the direction and faces the sealing member, the notch portion being substantially flat in a direction perpendicular to the direction,

the sealing member is provided between the housing main body and the rib on the outer circumferential surface of the protruding portion,
in the sealing member, a projection that protrudes toward the connecting object along the direction and engages the notch portion or the rib is provided, and
when viewed from the direction in which the connector is inserted, a thickness in a radial direction of the sealing member in a region where the projection is provided in the sealing member is larger than a thickness in the radial direction of other regions of the sealing member.

2. The connector sealing structure according to claim 1 , wherein
the terminal portion is a plate-like member having a plurality of contact portions provided on a plane, and
at least part of the notch portion is formed on an end side in a longitudinal direction of the plane in the protruding portion.

3. The connector sealing structure according to claim 1 , wherein
rigidity of the projection is higher than rigidity of other regions of the sealing member.

4. The connector sealing structure according to claim 1 , wherein
in the projection, a supporting member that supports the projection is provided.

5. The connector sealing structure according to claim 4 , wherein
the supporting member is provided inside the projection.

6. A connector sealing structure of a connector provided with a terminal portion that is connected to a connecting object, the connector sealing structure comprising:
the connector includes
a housing main body,
a protruding portion that protrudes from the housing main body toward the connecting object, and
the terminal portion that extends from the protruding portion toward the connecting object,

the connector sealing structure includes
a sealing member that is placed on an outer circumferential surface of the protruding portion; and
an engaging portion that is provided on the outer circumferential surface of the protruding portion and engages the sealing member, wherein

the engaging portion includes:
a rib that is formed on the outer circumferential surface of the protruding portion and locks the sealing member in a direction in which the connector is inserted into the connecting object, and
a notch portion that is formed by cutting part of the rib,

the sealing member is provided between the housing main body and the rib on the outer circumferential surface of the protruding portion,
in the sealing member, a projection that protrudes toward the connecting object along the direction and engages the notch portion or the rib is provided.
