A plate-shaped connector sealing device made of a water-resistant and elastic insulating material used between the other connector provided with a receiver,
The sealing device for a connector has holes through which the respective blades are inserted, and is recessed from one surface side so as to individually surround the holes or to surround all of the plurality of holes in a housed state. And an annular contact portion protruding toward the other surface.

In the connector seal device thus constructed, the blade of one connector is inserted into the hole of the connector seal device and inserted into the blade receiver of the other connector. The annular abutment individually surrounds the blades of the one connector or collectively surrounds each of the blades, and is formed between the one connector and the other connector by the annular abutment. The gap can be closed elastically.

In the sealing device for a connector constructed as described above, the annular recess blocks the intrusion of the liquid or the like due to the capillary phenomenon between the annular contact portion and the connector in contact with the annular recess. To work.

Further, in order to achieve the above object, a connector seal according to the present invention has a one-side connector having a plurality of blades and a blade receiver corresponding to each of the blades. A connector seal for a plate made of a water-resistant and elastic insulating material used between the other connector and the connector seal, the connector seal having holes through which the respective blades are inserted, and The peripheral edge of the hole is an annular protrusion protruding from one surface side.

In the connector sealing device having the above-described structure, the blade of one connector is inserted into the hole of the connector sealing device, and is inserted into the blade receiver of the other connector. The annular protrusion surrounds each blade of the one connector, and the annular protrusion can elastically close a gap formed between the one connector and the other connector.
