Patent attributes
The present invention is intended to provide a waterproof grommet structure which can be taken apart into its constituent pieces, i.e., a grommet, a connector, a terminal, etc., even after filled with waterproofing agent, to allow its maintenance to be performed. A waterproofing agent tank 2c is isolated from a hollow portion 2b which is consecutively arranged with a connector rib 2a, to form a separate compartment. The waterproofing agent tank 2c comprises an inlet 2d formed as an aperture thereon and configured to feed waterproofing agent therethrough; a first through-hole 2e penetrating between the inside of the tank 2c and the hollow portion 2b to form a link therebetween; and a second through-hole 2f penetrating between the inside of the tank 2c and an external environment to form a link therebetween. An electrical wire 4 is positioned in a manner that, after passing through the hollow portion 2b, it is positioned in a manner that, after passes through both the first through-hole 2e and second through-hole 2f while tightly adhered to the first through-hole 2e and second through-hole 2f, and then passes through the waterproofing agent tank 2c.
