Abstract

A sealing compound consisting of one-part liquid type moisture curing resin is covered airtightly with a permeable wall member forming a container, so as to harden together with the connecting portions of electric wires or the like by exposing the sealing compound to environmental moisture when inserting the connecting portions into the container.

Claims

1. Coating means for coating connected terminal portions of connection members, comprising:

a plastic container formed of a material which does not allow moisture to permeate therethrough, said plastic container having at least one wall member with air passages in the form of one of vent holes, slits and mesh holes;

an inner wall surface of said plastic container overlaid with a moisture-permeable non-woven fabric defining a filling chamber;

a single liquid type moisture curing silicone resin serving as a sealing compound contained in said filling chamber; and

a moisture-proof film enveloping said container to prevent moisture from passing through said air passages.

2. The coating means of claim 1, wherein said plastic container has a cylindrical shape.

3. The coating means of claim 1, further including a slit formed in said plastic container and extending along a longitudinal portion of said plastic container.

4. The coating means of claim 3, wherein a pair of hook members are provided extending along a respective pair of edges of said slit.

5. A coating assembly for coating connected terminal portions of members comprising:

a container having at least one wall member with air passages formed therein;

a moisture permeable material disposed along at least a portion of said wall member such that said moisture permeable material covers said air passages;

a moisture curing resin disposed inside of said container; and

a moisture impervious film enveloping said container to prevent moisture from passing through said air passages.
